This approach ensures that missions can extend beyond the limits of human endurance.

Regarding financial constraints, traditional manned missions entail significant costs related to life support systems, spacecraft designed for human occupancy, and extensive training programs.

Combining VR technology with robots not only reduces mission costs but also facilitates a more scalable approach to space exploration. Robots, controlled remotely, become versatile assets, adapting to diverse mission objectives.

In summary, the challenges in human space exploration are profound and necessitate innovative solutions. The integration of virtual reality (VR) with robotic systems could present in my view a transformative opportunity to overcome critical technical barriers and usher in a new era of space exploration. Let’s delve now into the underlying technical foundations of this integration and its potential impact on the future of space exploration.

Introduction to the concept of integrating VR and robotics for remote space exploration

As we face the challenges of exploring outer space, a groundbreaking solution arises at the convergence of virtual reality (VR) and robotics, with potential to transform our approach to cosmic exploration.

What are the technical foundations and theoretical framework of merging VR technology with robotic systems for remote space travel?

Virtual Reality (VR) is a technology that enables the simulation of a three-dimensional environment, allowing users to immerse themselves in a simulated reality. This is accomplished through the use of specialized headsets, motion-tracking controllers, and realistic audio feedback. By using VR technology to explore space, operators on Earth can experience extraterrestrial environments through the eyes of a robot, overcoming the limitations of distance.

This approach is using robotics as exploratory agents. Robotics in space exploration help deploy autonomous or remotely controlled robots with advanced sensors, manipulators, and communication modules. By integrating VR with robotic systems, they become our surrogates in the vastness of space. Operators can direct the movements and interactions of robotic explorers on distant celestial bodies with precision. That’s basically the concept.

The technical foundation involves integrating advanced controllers, similar to those used in motion capture technology, to enable precise manipulation of robotic limbs. These controllers capture complex hand and gesture movements to translate them into robotic actions.

Within the conceptual framework, operators wearing VR headsets and equipped with motion-capture controllers can extend their senses to control the precise motor movements of robots. This synergy enables delicate and context-specific interactions within the extraterrestrial environment.

However, communication in space is characterized by significant latency, which presents challenges for real-time control. Critical components include satellite networks, data compression algorithms, and efficient protocols. We need to create a durable communication infrastructure that permits real-time control of robots despite communication setbacks. This infrastructure fosters seamless interaction between operators and robotic explorers, spanning even vast interplanetary distances.

AI algorithms will be essential for autonomous decision-making by robots, allowing them to perform routine tasks independently, while human intervention would be reserved for nuanced decision-making.

In essence, the integration of VR and robotics for remote space exploration creates a symbiotic relationship between humans and machines, overcoming the challenges of human space travel and opening new frontiers in scientific discovery, education, and potential experiences beyond our planetary boundaries. The following sections will explore the technical intricacies, advantages, and potential challenges of this innovative approach.

Technical framework

The integration of VR with robot vision represents an interesting alternative for immersive and remote space exploration. Here is a summary of the technical framework to make it possible.

The use of VR headset for the operator on earth. VR headsets with high-resolution displays offer a stereoscopic view that simulates the depth perception of human vision. This immersive experience is crucial for operators to perceive their extraterrestrial environment with precision.

The use of robot-mounted stereoscopic cameras. They capture the surrounding terrain in 3D, and transmit the visual data to the VR headset. The operator, who wears the VR headset, perceives the alien landscape as if physically present, thus enabling a profound sense of spatial awareness.

Integration-wise, robot-mounted cameras would live stream video feeds to Earth, using advanced communication infrastructure to reduce latency. Operators would then be able to remotely control the robot, although with inevitable communication delays dictated by the vast distances in space. In scenarios where the robot is positioned on one of Jupiter’s satellites, for example, the transmission of signals would encounter substantial latency, resulting in a delay of several minutes between the robot’s actions and the operator’s perception.

Inside-out tracking systems on VR headsets capture the precise movements of the operator’s head and body. Motion controllers equipped with sensors track hand movements and gestures in real-time. The robot’s movements and the operator’s control inputs are synchronized through motion tracking. The VR system translates the operator’s head and hand movements into corresponding movements of the robotic explorer, creating a seamless and intuitive control interface.

Robots are equipped with sensors, such as cameras, lidar, and infrared sensors, which allow for a comprehensive understanding of the surrounding environment. By combining data from various sensors on the robot, sensor fusion algorithms create a holistic representation of the environment. The combined data is then sent to the VR headset to enhance the operator’s perception with comprehensive details of the surroundings, barriers, and weather conditions.

AR overlays integrate virtual information onto the real-world display. This technology improves the operator’s understanding of the environment by providing data that is specific to the context. Relevant information, such as navigation data or scientific measurements, can be overlaid onto the system for integration.

Requirement of advanced controllers for hand and gesture control

Integrating virtual reality (VR) with robot exploration requires the use of very advanced controllers for hand and gesture control. Here is a summary of the key technologies to master before any robotic space exploration with VR remote control.

Advanced controllers would incorporate haptic feedback mechanisms that replicate the sense of touch, enabling operators to remotely interact with their surroundings. In extraterrestrial settings, the operator’s control precision and situational awareness are improved by the ability to sense surface texture or object resistance.

The controllers are equipped with Gesture Recognition Technology, a technical innovation which allows the system to interpret intricate hand movements and gestures. The user would then be able to communicate intricate commands through gestures, allowing the robot to complete tasks with a level of precision comparable to human interactions.

Force feedback systems in controllers would mimic the resistance or force experienced in virtual environments, conveying the physical characteristics of remote locations to the operator. When the robot encounters obstacles or exerts force during a task, force feedback provides the operator with a tactile understanding of the robot’s interactions, aiding in precise control.

The controllers are designed with adaptive ergonomics that allow for a comfortable and intuitive interface, making it a technical innovation with operational significance. The ergonomic design enables operators to engage in extended control sessions comfortably, enhancing the efficiency of remote exploration.

Comparison between 3D rendering and motion capture technologies in animation

The integration of VR with robotic systems is influenced by the advanced technologies used in 3D rendering and motion capture in the field of animation. A comparison of these technologies offers insight into the technical underpinnings that enable immersive remote space exploration.

The integration of VR and robots combines robot vision and VR technologies to simulate extraterrestrial environments that offer a

realistic experience for operators on Earth. 3D rendering techniques in animation facilitate the recreation of lifelike environments for characters and scenes, promoting a sense of realism.

However, while operators make decisions by using the (delayed) visual feed from the robot’s sensors, animators manipulate characters and scenes in real-time using motion capture technology, making creative decisions as they work.

Advantages of robotic exploration

In the relentless pursuit of understanding our cosmos, the integration of virtual reality (VR) with robotic systems heralds a transformative approach to space exploration, offering numerous advantages over traditional manned missions.

Robotic exploration mitigates the risks to human health and safety posed by the unforgiving nature of space, which is characterized by high radiation levels and prolonged exposure to microgravity. Robotic exploration addresses the issue of human presence in hazardous environments by removing the need for astronauts. Operators are able to control robots remotely while immersed in virtual reality, thereby effectively mitigating the inherent dangers, such as radiation-induced health concerns, to human life. Additionally, this facilitates exploration in environments that would be otherwise perilous.

Traditional manned space missions come also with astronomical costs that involve among others, life support systems, spacecraft designed for human occupancy, and extensive training programs for astronauts. Robotic exploration provides a relative more cost-effective alternative as it reduces the complexity and expenses associated with ensuring human safety and well-being during space travel (outside the initial capital investment to mature the technology). The saved financial resources can be used to advance technology, extend mission durations, and broaden the scope of scientific objectives in the long run.

In addition, robotic explorers can endure the harsh conditions of space, including microgravity, without compromising human physiology, which may suffer physical toll. From navigating difficult terrains and withstanding extreme temperatures, robots offer an optimal solution for missions that would pose serious survival challenges to humans. Their resilience allows for more extensive and prolonged exploration, pushing the boundaries of our understanding of the universe.

As a conclusion, we can already understand the long-term benefits of robotic exploration, enhanced by VR integration, compared to human space exploration. By leveraging robotic systems, humans can explore further into the cosmos, uncovering its mysteries while also safeguarding the health and safety of explorers. This shift in space exploration marks a new era of discovery, where the capabilities of machines complement the curiosity and ingenuity of the human mind.

If sufficient intelligent species exist on the Universe, they would probably use this type of technique rather than biological forms.

Challenges and limitations

Integrating virtual reality (VR) with robotic systems offers a revolutionary approach to space exploration. However, there are significant challenges and limitations that must be addressed to ensure the success and efficacy of remote missions. It is imperative to navigate these issues carefully.

One of the primary obstacles for remote space exploration is the considerable communication lag resulting from great distances. When robots are located on far-off celestial bodies, such as a satellite orbiting Jupiter, signal travel time produces considerable delays that hamper real-time control. The delay poses a challenge to the idea of immediate responses, affecting the operator’s capacity to handle the robot with the promptness essential for specific tasks, especially ones necessitating quick decision-making.

The inherent communication lag results in tardy responses for robotic functions, especially in cases where swift intervention is crucial. During critical situations, such as when navigating around obstacles or responding to changes in the environment, delays can lead to less-than-optimal decision-making. This presents a potential risk, as untimely responses to unexpected challenges can endanger the success of the mission or cause damage to the robotic explorer. To mitigate these risks, it becomes crucial to strike a balance between autonomy and human intervention.

Finally, the incorporation of artificial intelligence (AI) in robotic systems creates intricate dynamics between autonomy and human control. AI-powered algorithms can improve a robot’s capacity to manoeuvre and execute habitual tasks independently. However, the effectiveness of these algorithms in responding dynamically to unforeseen obstacles would be under close observation. To establish the correct level of autonomy and the appropriate thresholds for human intervention, it is crucial to carefully evaluate the situation. The challenge is to develop AI systems that strike a balance between adaptive decision-making and human operator control over critical aspects of the mission.

To address these challenges and limitations, the VR-integrated robotic exploration field must navigate the delicate trade-offs between autonomy, control considering lags, and human intervention. Finding solutions to these challenges is crucial for realizing the complete potential of robotic exploration in the expansive and unpredictable terrains of our solar system and beyond.

Educational applications for Virtualians

The integration of virtual reality (VR) with robotic systems has potential for scientific exploration and educational opportunities, providing immersive experiences that go beyond conventional learning. That is in essence what I am interested in that topic keeping in mind the benefits for the Virtualia ecosystem.

VR immersion enables students and enthusiasts to experience the role of operators controlling robots on faraway planets. The inclusion of educational content in VR environments allows for interactive learning experiences.

Moreover, virtual reality technology provides students with the opportunity to explore alien landscapes, comprehend the difficulties of extraterrestrial terrain, and observe the complexities of scientific experiments conducted by robotic explorers. This first-hand experience promotes a deeper understanding of space science, sparking curiosity and passion for STEM (Science, Technology, Engineering, and Mathematics) fields.

Virtual Reality technology enables the development of virtual tours and educational simulations, providing a simulated journey to other planets. For instance, individuals can take virtual tours of Martian landscapes or the icy moons of distant gas giants, experiencing the awe of space exploration from the comfort of their homes. This not only engages the public in scientific endeavors but also opens avenues for space tourism in an educational context, expanding the horizons of experiential learning.

Robotic explorers would be equipped with 360-degree cameras to record their surroundings. These recordings would transport viewers to remote locations when viewed through VR headsets, allowing users to explore the surroundings in all directions and providing an unparalleled sense of presence and immersion. Such recordings will serve as valuable educational resources, offering a unique glimpse into the uncharted territories of our solar system.

In summary, VR-integrated robotic exploration has immense potential for educational applications that far surpass conventional learning methods. This innovative approach can inspire a new generation of space enthusiasts by leveraging immersive technologies. As a result, the Virtualia ecosystem would be the most appropriate place to develop such applications for educational institutions, space agencies, and content creators would probably be stimulated by such a deep appreciation of the wonders of the cosmos. These applications would enhance formal education and democratize access to space exploration experiences, rendering the cosmos a captivating and accessible realm for learners of all ages. This is very well aligned with the mission of Virtualia.

Human training considerations for remote operations

The shift toward remote operations in space exploration requires a comprehensive approach to training. Operators must be equipped to navigate challenges, such as communication delays, slow movements, and collaborative interactions with robotic systems.

Astronauts training to operate robots on far-off planets would undergo specialized training that blends traditional spaceflight preparation with immersive virtual reality experiences. This training could include using advanced controllers, understanding the complexities of robotic vision systems, and developing skill in interpreting the delayed signals of interplanetary communication (the most critical of all).

Astronauts trained in robotic control would then develop a comprehensive understanding of the technical aspects of the systems they will operate. This training is vital in promoting adaptability, enabling astronauts to move effortlessly between human spaceflight tasks and the complexities of remote robotic control, ensuring a complete skill set for extraterrestrial missions.

To adapt to communication delays and slow movements, scenarios during training could simulate communication delays experienced during remote space missions, enabling operators to adjust to signal transmission lags. Slow-motion simulations of robotic movements would prepare operators for reduced responsiveness while controlling in real-time. The training would promote patience and strategic thinking, allowing operators to effectively control robots even when immediate responses are not possible due to the limitations of interplanetary distance.

The training program should emphasize human-robot collaboration as a means to enhance efficiency. Training scenarios would include collaboration strategies to decide when human intervention is crucial or where tasks can be autonomously executed by robots. The operational significance of such training lies in understanding the strengths and limitations of both humans and robots, which allow operators to develop collaborative strategies that maximize efficiency. This entails task delineation based on each entity’s capabilities, creating a seamless interplay between human decision-making and autonomous robot actions for optimal mission outcomes.

To conclude, the training of astronauts for remote operations in robotic exploration is a multifaceted process that combines technical proficiency, adaptability, and collaborative skills. As humans transition from explorers in space to operating alongside robots, it is crucial to maintain continual training and development to achieve successful outcomes.

Ethical considerations on robotic exploration

As humanity enters the era of robotic space exploration, it is important to consider the ethical implications that arise alongside the pursuit of scientific knowledge and technological advancement. The integration of virtual reality (VR) with robotic systems presents a number of ethical dimensions, which are discussed in the following points.

The pursuit of scientific knowledge drives space exploration, but ethical concerns require a conscientious balance between discovery and the protection of extraterrestrial environments. To avoid unintentional harm to alien ecosystems, robotic missions must minimize disturbances. As such, our ethical responsibility is to establish protocols that prioritize non-intrusive exploration, prevent contamination of celestial bodies with terrestrial microbes, and avoid inadvertent disruption of potential extraterrestrial life. Balancing scientific curiosity with respect for the unknown and the preservation of the environments being studied is crucial. At some point of human exploration advances, a special committee made of world experts would take such role.

Ethical considerations must address intentional contamination, unauthorized interference with other nations’ missions, and responsible technology use to avoid adverse consequences or conflicts in space.

In brief, ethical considerations must be inexorably integrated into mission planning and execution as we venture into the frontier of robotic exploration. A harmonious balance between scientific curiosity, and ethical responsibilities, will ensure that the pursuit of knowledge beyond our world adheres to ethical principles.

Conclusion

In the pursuit of unraveling the enigmas of our universe, the convergence of virtual reality (VR) and robotic systems presents an innovative paradigm, heralding a new chapter in space exploration. This expedition is characterized by several advantages, including the reduction of risks to human health, cost-efficiency, and the capacity to overcome hostile environments through sturdy robotic explorers.

However, this approach has its challenges. Communication delays, slow response times, and the need for a delicate balance between human intervention and AI autonomy highlight the complexities of navigating space through remote-controlled robotic missions.

The potential impact on future space exploration is significant. VR-integrated robotic systems expand scientific inquiry and facilitate immersive learning experiences and innovative applications.

Introduction

In the fast-changing world of retail, technology is transforming established norms, and supermarkets are no different. By deploying Internet of Things (IoT) technologies, specifically Radio-Frequency Identification (RFID), supermarkets embracing technology would be poised to embark on a new epoch that will revolutionize the shopping experience from product ingress to quick checkout. Of course, traditional supermarkets would exist alongside providing more a human touch to the shopping experience. Nevertheless, a certain number of shoppers would be interested by speeder checkouts. But not only.

Supermarkets have faced inventory management, theft prevention, and the need for quick checkouts as perennial challenges. However, with the advent of IoT, they can now address these challenges comprehensively. As we explore this transformative approach, it becomes clear that the role of the cashier is going through a significant shift.

The traditional checkout counter, where cashiers scan each item, may soon be a thing of the past. Instead, a seamless and efficient checkout system powered by RFID technology is set to revolutionize the customer experience in supermarkets. Though this transition could make the traditional cashier role unnecessary during checkout, it offers a chance for cashiers to transition to more value-added tasks within the larger supermarket system.

In this article, I discuss implementing RFID technology in supermarkets, specifically for tracking individual product packages and smart shopping carts. Cashiers will focus on optimizing product placement, streamlining logistics, and enhancing overall supermarket efficiency. I will cover some of the technical aspects of RFID implementation to ensure clarity and precision. As we delve into the intricacies of real-time inventory management, theft prevention measures, and the lightning-fast checkout process enabled by IoT, we must also contemplate the wider ramifications for the workforce and the ever-changing dynamics of the supermarket industry. Embracing innovation is not the only aspect of the transition into this IoT-powered supermarket future, but reimagining roles and responsibilities to achieve an even more efficient and secure retail environment is also of worth considering.

The role of RFID in real-time inventory management

RFID technology basics

Radio Frequency Identification (RFID) is at the forefront of the technological revolution that’s transforming supermarket inventory management. RFID tags are tiny electronic devices with a unique identifier and microchip. They communicate wirelessly with RFID readers, using radio frequency signals to facilitate data exchange without requiring direct line-of-sight. The tags are available in different forms- passive and active- each possessing unique functions in the RFID ecosystem.

Passive RFID tags do not have internal power sources hence they rely on energy from the RFID reader’s signal for operation. They are cost-effective and lightweight, which makes them suitable for some applications. On the other hand, active RFID tags have built-in power sources that increase their range of functionality and data processing abilities. The variety of RFID tags enables a nuanced approach to real-time inventory management, accommodating the diverse needs of the supermarket environment.

RFID readers and antennas are crucial to the success of real-time inventory management, working in tandem with the RFID tags. To activate nearby RFID tags, readers positioned strategically throughout the supermarket emit radio frequency signals. The readers capture the unique identifier transmitted by the tags to initiate a seamless flow of information. The efficiency and accuracy of this process rely on deploying antennas responsible for emitting and receiving RFID signals.

Antennas would vary in shapes and sizes to cater to specific requirements of the supermarket space. High-frequency antennas work well for short-range applications, like point-of-sale stations we would find in Virtualian supermarkets. Ultra-high frequency antennas, on the other hand, are excellent for long-range scenarios and are ideal for tracking products across very large supermarkets (for instance those found in Asia). By orchestrating RFID readers and antennas, a dynamic network is created, allowing for a real-time data exchange infrastructure that forms the backbone of modern inventory management systems.

Integration of RFID in Supermarket Products

The potential of RFID in real-time inventory management becomes transformative when RFID chips are seamlessly embedded in individual product packages. This involves attaching RFID tags to products during the manufacturing or packaging stage, ensuring a discrete yet powerful means of identification for each item. The integration is adaptable and expandable, accommodating products of different sizes, shapes, and materials.

These packages embedded with RFID technology become intelligent entities, able to convey their identity and status in real-time as they traverse the ‘supply chain’ of the supermarket. The accuracy of RFID technology enables the generation of a digital fingerprint for every product, simplifying the tracking process and enabling precise insights into inventory movements. This integration not only reduces the chance of manual tracking errors but also enables a comprehensive and automated inventory management approach.

Benefits of Real-time Inventory Monitoring

Real-time monitoring of inventory enhances operational efficiency by providing quick and accurate insights into inventory levels and movements.

Real-time monitoring of inventory, powered by RFID technology, goes beyond the limitations of traditional inventory systems. The advantages are many, including enhanced accuracy and improved operational efficiency.

On accuracy. RFID technology enables almost perfect accuracy in inventory tracking. The real-time visibility into product movements reduces the likelihood of errors associated with manual data entry or barcode scanning.

On efficiency. Traditional inventory audits can be time-consuming and resource-intensive. However, supermarkets can now automate this process using RFID technology. This allows for continuous monitoring of stock levels without disrupting daily operations.

Real-time insights from RFID also help supermarkets optimize stock levels, preventing stockouts and overstock situations. This not only improves customer satisfaction but also reduces wastage, leading to an enhanced customer experience. With accurate and current inventory information, supermarkets can offer customers real-time product availability, creating a more seamless and satisfying shopping experience.

On inventory analytics. RFID-enabled inventory systems generate a wealth of data that unlock the potential for advanced analytics. Supermarkets can gain insights into consumer behavior, demand patterns, and operational efficiency, which inform strategic decision-making.

If on top of this, we add real-time accounting with the blockchain with real-time business intelligence dashboards, product visibility from Virtualia Shop (with remote orders) and 3DVRAR views of the product, Virtualian supermarkets could get an advantage compared to competitors.

The integration of RFID technology in supermarket products can revolutionize inventory management. Combining RFID tags, readers, and antennas has the potential to automate tracking and enhance precision, efficiency, and overall intelligence in the supermarket industry.

Smart Carts: transforming the shopping experience

Incorporating RFID Sensors in Shopping Carts

The transformation of the regular shopping cart into an intelligent companion with RFID technology is a major enhancement to the supermarket experience. This integration involves incorporating RFID readers directly into the cart’s infrastructure, which function as the sensory receptors of the cart.

These readers constantly communicate with the RFID tags in product packages, detecting as items are added to the cart.

The RFID readers in the cart work together to activate and read the RFID tags on each product, maintaining an accurate and current inventory of the cart’s contents.

The RFID readers in the cart work together to activate and read the RFID tags on each product, maintaining an accurate and current inventory of the cart’s contents.

With this continuous communication, the cart can dynamically and in real-time understand what items are inside, paving the way for a game-changing shopping experience.

Cost Computation in Real-time

Real-time cost computation is a major advancement in how shoppers will use their digital carts. When items are added or removed, RFID readers quickly update the cart’s digital record. This record includes pricing information for each RFID tag, making it easy to automatically calculate the total cost of items in the cart.

This has significant implications for shoppers.

Shoppers get immediate feedback on how their shopping choices impact their finances, helping them make better decisions.

Uncertainty at the checkout is a thing of the past; instead, shoppers understand their expenses from start to finish. This improves the shopping experience and promotes financial control and transparency.

User Interface on Smart Carts

As I envision, there are several benefits of having a user interface on smart carts:

The smart shopping cart has a user-friendly interface that shows the costs of each item scanned.

The digital display is placed within the shopper’s line of sight for convenience.

The display updates in real-time to show the total cost of all items in the cart, helping shoppers make informed purchasing decisions.

The itemized cost display is an essential tool for managing finances and engaging shoppers actively during the shopping process. By showing the costs of each selection, shoppers can prioritize their choices, make real-time adjustments, and maintain a budget-friendly approach to shopping:

The smart cart’s user interface goes beyond itemized costs, providing an array of features to empower shoppers. It gives a complete look at the entire shopping trip, with a continuously updated total, prices of each item, and maybe even discounts tailored to the shopper. This kind of openness lets shoppers have more control over their spending, making shopping less stressful and more satisfying.

The interface could also come with budgeting tools, so shoppers can set limits on their spending or get notifications when they get close to their set spending limit.

The inclusion of RFID sensors and shopper-friendly interfaces in smart shopping carts should not only boost financial management, especially in times of high inflation but also promotes trust and contentment among buyers.

Beyond the mere act of carting items, these technological innovations will empower shoppers with real-time information, financial transparency, and a level of control that transcends traditional shopping norms.

Addressing shoplifting challenges

Incorporating RFID Sensors in Shopping Carts

RFID technology is a powerful tool in the fight against shoplifting in supermarkets. By using RFID tags, every product is equipped with a traceable entity, allowing for constant monitoring. As these products move through the store and into customers’ carts, the RFID readers continuously update the system with their locations. This real-time monitoring serves as a proactive deterrent to potential shoplifters. The visibility into the precise location of each item enables swift identification of anomalies or irregularities, allowing security personnel to intervene before theft occurs. By transforming each product into a monitored asset, RFID technology establishes a robust foundation for preemptive security measures.

RFID systems can analyze shopping patterns and sense unusual behavior that may suggest theft (like a misplaced item in the smart cart). Alerts are triggered in real-time when items are removed and returned to shelves or linger in blind spots. These alerts allow security personnel to respond quickly and prevent potential theft.

Another point, would be integrating RFID technology with advanced analytics to improve alert systems, ensuring accurate identification of legitimate security threats. Supermarkets could use RFID to continuously monitor the shopping environment, enabling proactive measures against shoplifting and promoting a safer and more vigilant retail space.

Noteworthy to say, that if everyone was ethical, such unethical behaviours would not be happening and such measures would not be needed.

RFID technology changes shoplifting

It carefully tracks products from shelf to checkout to reduce blind spots where theft could happen. The transparency of RFID-equipped items in shopping carts, with real-time monitoring, minimizes shoplifting opportunities.

Furthermore, RFID affects the psychology of theft. The knowledge that every product is being actively tracked and monitored will act as a strong deterrent.

The IoT exit gateway for a lightning-fast checkout

Designing an Efficient Exit Gateway

The essential part of the fast checkout process is the ‘IoT Exit Gateway’, which is embedded with high-precision RFID door sensors. These sensors are accurately designed to quickly capture the RFID data from each product as it leaves the supermarket. They ensure a smooth transition from the store to the checkout process.

Highly sensitive to RFID signals, these sensors at the store’s exit will serve as the last checkpoint before a customer leaves. They quickly read the RFID tags on the items in the cart as it passes through, creating a detailed, real-time inventory snapshot. This maximizes accuracy in the checkout process, boosting the system’s overall efficiency.

Plus, this system easily integrates with supermarkets’ existing infrastructure. The ‘Exit Gateway’ acts as the center that brings together the whole IoT ecosystem, from the RFID readers in shopping carts to the centralized inventory management system.

The integration goes beyond hardware, as it includes software interfaces that make communication between the Exit Gateway and other components of the supermarket’s technology stack smooth. This easy connection guarantees that the up-to-date info gathered at the exit moves easily into the system in the background, updating inventory records and making it easier to quickly calculate the total cost for checkout. The gateway’s focus on working together helps create a smooth technological experience within the supermarket setting.

Workflow of the ‘Exit Gateway’

As customers get near the ‘Exit Gateway’, the precise RFID door sensors start working, starting a quick verification process. The sensors scan the RFID tags on every item inside the cart, comparing this data with the details kept in the centralized inventory management system. This quick verification is meant to be immediate, making certain that the exit process is quick and effective.

Any errors found during this check will cause alerts that prompt actions to fix them before the shopper leaves the store. The aim is to balance speed and accuracy, to offer a hassle-free exit process while maintaining the checkout’s honesty.

Additionally, as real-time verification occurs, the Exit Gateway calculates the total cost for checkout. Using the data gathered by the RFID sensors on the doors, the system retrieves pricing details for each product. By integrating seamlessly with the supermarket’s technical backend, the Gateway can obtain the most current pricing data and carry out necessary computations.

Shoppers can view an accurate total cost on the user interface immediately, allowing them to be fully aware of their expenses before exiting the store. This simple process eliminates the use of regular checkout counters, improving the supermarket experience by giving customers a quick and clear way to checkout.

To conclude, the ‘IoT Exit Gateway’ will transform the checkout by using high-precision RFID door sensors and seamless integration to create a fast and efficient process. This technology will speed up the checkout process by 10 as of 2021 and will show a move towards a more advanced and customer-focused approach in supermarkets.

Challenges and considerations

Technical Challenges

Implementing RFID technology in supermarkets presents technical challenges. One major concern is balancing the range and precision of RFID systems. An optimal RFID range is crucial to accurately detect and track items throughout the supermarket. However, a broader range could cause interference and unintentional reads, which would negatively impact the system’s precision.

Fine-tuning the range of RFID to strike the right balance between coverage and accuracy is a delicate task. Achieving precision without sacrificing range becomes paramount, especially in crowded supermarket environments where products are densely arranged. Overcoming this challenge will involve iterative testing, using advanced signal processing algorithms, and potentially deploying RFID systems with adjustable parameters to adapt to diverse supermarket layouts. I assume by 2030 those technical challenges should be overcome and become mainstream.

Additionally, scalability issues need to be addressed in large supermarkets.

Large grocery stores pose a distinctive set of challenges in terms of RFID system scalability. To ensure peak performance, RFID solutions must effortlessly scale given the considerable number of products, shoppers, and the store’s expanse. The challenge of scalability extends beyond the volume of RFID tags and readers to the backend infrastructure responsible for processing and managing the large influx of real-time data. Achieving scalability will demand a sturdy architecture that can manage thousands or even millions of RFID-tagged items simultaneously. To guarantee the system remains responsive and reliable, even in the largest supermarket settings, using for instance cloud-based solutions, distributed databases or a ledger like the Virtualia blockchain, and effective data processing algorithms will be essential. Balancing scalability while remaining cost-effective and keeping communication latency low will be crucial aspects in surmounting this technical challenge.

About ethical and privacy concerns

As more supermarkets will probably adopt IoT and RFID technologies once they become mainstream, concerns arise regarding the security and privacy of customer data. RFID tags on products transmit unique identifiers, and although these are not directly linked to personal information, the potential for correlating data remains. Securing this data from unauthorized access, interception, or misuse is of utmost importance.

Implementing strong encryption protocols, secure communication channels, and access controls are crucial measures to prevent data security threats. Furthermore, supermarkets must establish explicit and transparent policies on how they handle, store, and share customer data. Maintaining a delicate balance between achieving the benefits of RFID-enabled services and respecting customer privacy plays a critical role in promoting trust and ensuring ethical data practices.

Additionally, the widespread implementation of RFID technology leads to new risks, such as the possibility of malevolent parties exploiting system vulnerabilities. Consequently, threats such as unauthorized RFID tag duplication, data tampering, or interception must be addressed proactively.

Supermarkets will have to implement comprehensive risk mitigation tactics to safeguard the integrity of their RFID systems and customer privacy. Proactive risk mitigation involves conducting regular security audits, penetration testing, and continuous monitoring. Collaborating with cybersecurity experts and industry partners will also help to stay ahead of emerging threats. This would in a nutshell lead to a new set of cybersecurity services as with new emerging technologies.

To conclude, while RFID technology brings transformative benefits to supermarkets, it is essential to address technical challenges and ethical considerations to guarantee the seamless, secure, and privacy-respecting implementation. As supermarkets navigate the technological frontier, they must take a holistic approach that considers both technical and ethical dimensions to create a future-proof and responsible RFID ecosystem.

Conclusion

The integration of IoT technologies, particularly RFID, through Virtualia supermarkets will greatly transform the supermarket industry. This transformation will go beyond the operational enhancements and will include a significant redefinition of the customer experience and the overall retail dynamics, including new type of employment.

With the precision of RFID tags, readers, and intelligent carts, a dynamic and immediate monitoring system will be established. This should ensure accurate stock levels and empower our supermarkets with real-time insights and data analytics. Manual inventory audits and the ongoing battle with stockouts or overstock situations should no longer be necessary thanks to the efficiency and foresight provided by IoT-enabled inventory control.

Coupled with 3DVRAR technology and our Virtualia Shop network, the supermarkets will change completely the way we do food purchases.

In addition, RFID technology can improve theft prevention and

and efficient checkout, providing increased security in supermarkets. The “IoT Exit Gateway” we have defined will redefine the checkout by eliminating traditional cashier roles. To compensate for the loss of these jobs, we will transform them into logistics tasks and consumer information or interaction.

We can achieve these changes by combining high-precision RFID door sensors with seamless integration to provide an efficient, secure, and lightning-fast checkout experience, marking the pinnacle of supermarket transaction efficiency.

Note: those models are still under fine-tuning and are very complex to handle for obvious political, economical, and financial reasons.

The participation quota for blogs, articles, wikis, and dApps review

Principle

The algorithm will favor content that encourages communication between users to the detriment of trolls, scathing news from brands or media.

Commenters will have to upvote what really matters because liking or disliking is a scarce resource — quite the opposite of what fuels the current business model of social networks where upvoting, liking, retweeting which metric benefits only their private owners and not the community itself. Banning has been authoritative and not based on a clear penalizing and transparent system.

In Virtualia, each user has its own participation quota. When you receive a downvote from someone, you will lose some participation power. When you receive alike, you will gain some additional participation power. This dynamic enhances rational behavior between members instead of compulsion and trolling behaviors that are very nasty drawbacks of online discussions. This is the power of fixed scarcity.

When the first Virtualian is approved by the network, he receives an amount of participation point that is allocated at a certain block height. He will have a wallet with a certain amount of participation points that is equivalent to the average participation point in the system. So, if nothing had changed, all Virtualians will have the same participation point, thus guaranteeing equality in terms of participation power.

By considering the following variables, we can get the formula that gives the participation power to each new member:

· t= present block height corresponding to a time (weeks).

· T0= Block height when the user registered, expressed in weeks

· A0= amount of participation points allocated to the average user at block height T0 in order to match the current allocated points to the average user.

· Pt= Total points allocated for a given user at time t.

The formula is not that complicated. It states that a maximum of 1000 pts is given to any user at any given time, and it starts with the average of points from all existing users when onboarding and the allocation point is increasing smoothly along a sigmoidal function to reach halfway after 26 weeks.

The parameters 10 and 5 allow to spread of the distribution of weekly awarded points. This is purely arbitrary.

We estimate that one year (52 weeks) is a sufficient time for the first users in the initial phase duration to get acquainted with the participation power, in order to train and avoid mistakes. To be wise it requires time. After a bit more than 1 year, depending on the distribution and density of new entries, we should enter a new phase where all new users get 1000 points. At that time, however, there will be a dispersion of points among the first adopters due to the dynamic of reward and penalization. The total quantity of participation points in the network will grow proportionally to the number of users (N) while the average user power will grow inversely to N.

By guaranteeing an equal average starting point for every participant regardless of the time they decide to join the network, we state that every voice has potentially the same right of expression. However future actions of the user will determine his participation power and that is somewhat that belongs to the free-will of people.

The concept of quota is changing the paradigm to what people are used to seeing on the internet, social media, and for the sake of freedom of speech. In the actual system, trolling or bashing make a huge portion of comments nowadays. In a nutshell a lot of useless expressions. So, the system has to find an incentive to promote constructive discussions.

Dynamics — exchanging participation points between members

Each action has its own reaction. When liking a comment or disliking, you use points so it is a scarce resource to use carefully. That way spammers, spoilers, trolls are quickly banned economically because they lose the power to express their opinions later. If a lot of commenters downvote you, the more points you can lose. It also goes on the other side. The weight depends on the reputation of the commenters and other criteria like the detection of trolls later by an AI, bashing, irrelevant comments like pictures. However, the danger happens when someone creative goes against the dogma. In this case, he may receive strong downvotes. It is important to distinguish who has very bad behavior like racism from those with a different opinion. It is still very difficult for an AI to detect it, and for this reason, because we cannot allow a human to monitor all comments, the maximum point you can lose be capped. By transferring your points by the action of liking or commenting, you participate in the chain of actions and reactions among the community participants.

When comparing that method with a limited resource concept, to uncapped likes and tweets in other social applications, we force a more rational behavior rather than impulsive liking, sharing fake news, or trolling to unnerve readers.

The true value of the network does not reside on the scarcity of the participation frequency but on its ability to share valuable comments for all readers.

Calibrating the transfer price of comments, shares, and likes

If we look to the most used social platform to provide information on the average estimated value of comments, shares, and likes it appears that there are in 2021, about 12 likes, 5 comments, and 1 share per month per user, according to Hootsuite. Those figures can vary greatly given the type of platform and per country and generation. Some formats may also impact the average; people are more inclined to pictures for which according to kissmetrics[1], they “get 53% more likes, 104% more comments, 84% click-through on links than text-based posts” in 2017.

Cost for posting, liking, sharing

The cost of a comment, like/upvote, and share/retweet is different. It is easier to like, and it expresses a simple expression. Sharing is then a bit more complex because you express not only the fact you like, but you spread the expression, meaning more. Finally, clearly expressing your idea in comments is even more powerful. Long articles are the most powerful mean to express digitally alongside videos. Finally, the frequency and the diversity of actions are also considered.

Calibration should be dynamic and done once a year, derived from insights of published statistics on major online social networks. Here is a simple start given current social media usage:

The max cost between cost1 and cost2 is taken. Cost2 is there to put some constraints on high-ranking participants in order for them to stay focused and careful, and not have infinite commenting shots available.

QtyL, QtyS, QtyC are the number of actions associated with cost1 or cost2.

For instance, with 1000 starting credit points, you could comment on 100 long videos, share 25 long texts, share 100 pictures or like 500 very short videos or comment on 400 pictures and like 1000 pictures.

Once you posted an article, video, or comment. There are many ways to earn more credits or lose them.

Losses

You lose participation credit points when you receive a dislike, a downvote on your publication, shared picture/text/audio/video, or comment in a thread.

Losses are capped to avoid losing too many points in a worst-case scenario, also in case you are rejected by a high reputation guy who is sharing an opposite opinion. Max loss is capped at 1%.

Gains

While you spend credit points on expressing your view and can lose some additional points from the audience, here is finally how you can compensate them:

Every credit point transferred is decomposed into two parts:

- 10% of the points go to the author, but this figure is capped at 10 times the maximal cost of such action in order to respect the concept of “one order of magnitude principle”,

- and 90% points go to the Participation fund of Virtualia.

The participation fund collects points from the interaction between members and then distributes them equally to every Virtualian.

For videos, to avoid Pareto law inflation, a function is applied to smooth viral effect such as:

The constraint max and min enable to reward interestingly points starting at 1k views, and cap viral videos (1 billion views) by 1 million points.

For 1K views or less, no more than 1 point is awarded to the video creator. It is reached with either 10 likes or 2 comments or 1 share for a short video (costing 10 pts for the commenter but only 10% i.e., 1 point is transferred to the video creator).

For 1M views, no more than 1000 pts are awarded.

A more complex mechanism needs to be considered to avoid hacking the system such as sharing or duplicating viral content from someone else for which they are not the author.

Time limitation

It is clearly necessary to time limit old posts, in order not to be penalized for things said in the past. You may have changed your opinion since and cannot lose too much point for old ideas. Thus, a time impact on the way you earn and lose points is necessary to consider.

If everything was stopped, it would take a year to converge everyone back to 1000 credit pts.

What happens if not enough credit to express oneself?

Surely this is due to having negative social impact behaviors. Normally you should be compensated if you write great articles, comments that are sincere, profound of meaning, and with ethics. You will be authorized read-only access only but take in mind that there is a monthly participation fund redistribution to all users so you can earn back credit and work hard to improve your participation power.

We will not use the Virtualia coin or a token to avoid financial transfer of participation credits as media or trollers could pay for it, providing bad quality content in the network. Participation point is thus an untransferable asset as is your life. It is an expression of yourself but acts as a utility so by holding Virtualia coins (naturally all users of the network) are allowed to receive an equal portion of the redistribution participation fund.

Other networks’ reputation

We could also integrate some complementary reputation systems to the Virtualia network via API. Those reputation scores will be added for each user profile. Contributors whole apply to a Request for Services from the Foundation

For instance, a reputation system is included in the Request Network to guard against phishing and bad payers but also companies that do not pay their invoices on time. Best members may receive cost reductions or access to custom extensions. Those scores can be linked to a user of the network adding new data on his actions.

Concluding remarks

We have explored some roots for participating models in this FAQ. Those concepts can be extended to some other form of reputation models.

In any case, we will submit those ideas in a poll to Virtualians. Only upon a large adoption rate (2/3), this kind of suggestion would be investigated further and then implemented.

Voting mechanisms are methods used to cast and count votes in elections. The use of technology such as blockchain and efforts to increase accessibility, transparency, and security are likely to shape the future of voting mechanisms.

In this article we are going in depth into some voting mechanisms. This is extremely important in the Virtualia ecosystem and is the basis of any correct representation of the people.

Part 1: In-depth analysis into the voting system

The voting system problem

The problem to solve:

Aggregate a set of social preferences, i.e., a set of individual preference choices into a social preference order.

By doing this, we are defining the social-choice function that is a transition operator from a set of individual preferences to a collective preference outcome. The voting system allows to elect, to choose a set of winners, define a sports winner, or choose the best project given a set of criteria.

This problem of aggregating preferences is found in many disciplines: in welfare economics, where one attempts to find an economic outcome that would be acceptable and stable; in decision theory, where a person has to make a rational choice based on several criteria; and finally in voting system mechanisms for extracting a decision from a multitude of voters’ preferences.

There are a lot of studies made since the French Revolution as it became an object of academic studies and became again a hot trend in recent years thanks to the disruptive technology of the blockchain. Tools influenced by the game theory developed during the middle of the 20th century helped to understand better the limits of an ideal voting system (Strong Nash Equilibrium or Pareto efficiency).

The use of mathematical criteria to evaluate the voting system explained that some criteria are actually mutually contradictory (Arrow’s impossibility theorem) or that strategic voting (by a group of users, cartel, or colluded) is unavoidable in certain circumstances for any voting system (Gibbard-Satterthwaite theorem). However, there are applicable in certain conditions and under some hypotheses, we will avoid. We will bring incentives for trusted authentic votes that reflect the true preference choice of the individual as much as possible with the current BC technology (and at least it is an improvement from the current system).

There are two models for two types of mathematical questions: either to choose a single answer or winner, (a single-winner method) or to choose a set of winners or answers (a multiple-winner method) given a set of choices — called « variant question » (less than 2, or more than 3).

Properties

The ideal model has to present a set of suitable properties to be realistically acceptable and judged as fair by a large majority of educated people to represent an ideal form of the voting system present in the Virtualia ecosystem to be aligned to its political freedom and decentralized concept of community. Note that note all properties are possible thanks to known theorems. But the chosen voting system will satisfy most of them.

1. Universal: should represent a deterministic collective choice and be defined in all possible cases. The social welfare function should yield a unique and complete ranking of societal choices.

2. Non-Diktat: No vote can make the final decision whatever the preferences of others.

3. Anti-collusion: No explicit cartel should have enough power to control the whole decision process whatever the other votes.

4. Unanimity: equivalent to a Pareto optimum (i.e., Pareto efficient[1]). If every individual prefers a certain option to another, then so must the resulting societal preference order. The social welfare function will be minimally sensitive to the preference profile. It includes monotonicity (An individual should not be able to hurt an option by ranking it higher.) and surjective sovereignty (any resulting order is possible).

5. Relative representativeness, i.e., when entities prefer one option to another, the social function choice should reflect this same preference to the society.

6. Independence of irrelevant alternatives: If a third choice appears, it should not modify the precedent preference order, i.e., if A>B in {A, B}, then {A, B, X} should not imply A<B.

7. A criterion weaker than IIA proposed by H. Peyton Young and A. Levenglick called local independence from irrelevant alternatives where two characteristics are needed: first, the winner must not change, and secondly, the option that finished in second place must become the winner.

8. Respect of the individual choice spectrum: any entity can vote, and its preference order should be generally fairly represented in the ballot.

9. Robustness to strategical voting or strategic nomination: while it is impossible for an ideal voting system to avoid strategic voting in all cases, its probability of occurrence should be low enough to be confident in the voting system given a reasonable base count of voters.

10. Non-mathematical criteria requirement: simplicity for the voter, speed of vote-counting by computers, the potential for fraud or disputed results, and, for multiple-winner methods, the degree of proportionality produced.

Constraints

The ideal voting system consists of a set of constraints:

• An egalitarian index limit (based on Gini coefficients) that compares the well-being of individuals to the bad-being of the most unfortunate within the Virtualia community. While less utilitarian than the most economical system in use, i.e., the total welfare is lower than with a pure utilitarian system, the system avoids extreme distribution in terms of the voting power[2]. This is mandatory when mixing moral representative entities with individual entities in a voting election, or between individuals only due to a high level of rewarding point discrepancy (the extreme case being the newcomer in the Virtualia ecosystem, and the best ever possible actions taken by an entity since the inception of the Virtualia existence).
• Money power is unrelated to power voting. A rich individual (as rich as illimited) cannot offset by money the outcome of a majority of voters against his choice.
• Collusion, cartel, monopolistic, plutocratic, oligarchy, and dictatorship system forms are strongly avoided (but not possible to state it as impossible) and countermeasures will be able to be taken within the Virtualia community if a quorum ratio (petition) is reached.

Assumptions

The voting system assumes:

1. Vote should have a set of 3 inviolable characteristics: anonymity, authentication, and trustworthiness of the ballot[3]. Trustworthy of the ballot is fostered by an incentive to vote by reward (input of the Virtualia reputation score system), helped by anonymity guarantee while authentication is a characteristic of the blockchain technology used at the Virtualia platform level. The authentication robustness will improve with more technology integrated[4].

2. The vote characteristic is the same whether it is at the moral entity level (e.g., a representative group) or the individual level. Only weights can differ depending on how many sub-entities in Virtualia are represented by the moral entity[5].

Conclusion of part 1

• Because of the impossibility to satisfy all properties, constraints, and assumptions. We decided to choose for the transition phase, the best existing voting system. The voting system for the equilibrium phase is under research investigation and will be tested in practice among the Virtualia community in real cases.
• While most criteria are tested for any possibilities, we strongly believe that the probability of occurrence of a breach is more important than finding the mathematical perfect solution in all cases. Life is made of constraints, constant evolution due to our understanding and modeling of the world. At this level, and because this is about social science, mathematics is dangerous as a final decision making « cold » tool but can be very helpful mixed with practice tests, and probabilistic arguments to decide which is the best voting system that will not disequilibrate the ecosystem within Virtualia at the highest probability. Countermeasure’s mechanisms are also there to avoid any bug in the voting system that will breach the moral concept of egalitarianism welfare (see constraints).
• We will set a voting model for a single-winner election and another for a multiple-winner election with realistic implementation (ranked pairs or head-to-head methods are thus discarded).
• The voting system should support individual freedom and the general interest.

Part 2: Mathematical criteria for Single Winner

Evaluation of voting systems using mathematical criteria FOR SINGLE WINNER VOTING SYSTEMS

Several different criteria can be used for voting systems in an election:

To compare systems fairly and independently of political ideologies, voting theorists use voting system criteria, which define potentially desirable properties of voting systems mathematically. We defined them in parenthesis.

We assume that the head-to-head competition such as the ranked pair method is the most efficient of all but impracticable. A second-best choice system has to be chosen satisfying as much as mathematical criteria, in addition to the properties and constraints defined in the first part of the presentation (annex 25.1).

1. Smith criterion (also complies with Condorcet Criterion, so MOST IMPORTANT OF ALL)

2. Condorcet criterion (VERY IMPORTANT) => Majority criterion

3. Condorcet loser criterion (a Condorcet lower will never win) (VERY IMPORTANT)

4. Majority criterion (satisfied if Condorcet criterion is met)

5. Mutual majority criterion

6. Independence of clones’ criterion (Spoiler effect needs to be avoided)

7. Independence of irrelevant alternatives — IIA

8. Local Independence of irrelevant alternatives — LIIA

9. Independence of Smith-dominated alternatives — ISDA

10. Consistency criterion

11. Monotonicity criterion (VERY IMPORTANT)

12. Participation criterion (VERY IMPORTANT)

13. Reversal symmetry

14. Polynomial time

15. Resolvability criterion (Probability should determine if relevant)

16. Summability (NOT anymore with a computer counting system)

17. Later-no-harm criterion (IMPORTANT to fight bullet voting)

18. Favorable betrayal criterion (VERY IMPORTANT)

19. Majority loser criterion (implied by Condorcet Loser criterion or mutual majority criterion so WEAKER)

20. Plurality criterion (weak property that surely must hold in any real election), using defeat strength

Labels 1–5 are results criteria absolute.

Labels 6–13 are results criteria relative.

Labels 14–16 are ballot-counting criteria.

Labels 17–18 are strategy criteria.

Labels 19–20 are weak form criteria.

Limits

Strategic voters acting in their own greedy interests are not considered. Not all voters are honest. This may extent some methods to be a subset of another wider method, hence being reduced to its simplest form that its ideal functional form. We can think about the range voting method where dishonest voters would be able to trick it such it becomes similar to approval voting. Determining the % of strategic voters among humans (as we are not robots) is a difficult task (social science changes all the time). But we can parameter simulations to account for all range of possibilities in strategic/honest votes and just say which method is the best in “average”, not the actual best-fitted method to the actual voting habits, which would vary year on year as this may be more a psychological study than statistical.

The ballot format requirements

This step is very important to express fully and fairly as much as possible the preferred choice of the voter as stated in the first part conclusion.

• The ideal ballot type would be cardinal (scores calibrated within a scale) instead of ordinal ranking to express the power desirability of a candidate instead of constant distance (when using ordinal raking, 1>2 is equivalent to 2>3 in terms of distance and do not state how good is 1 compared to 2 relatively to 2 with 3).

However, the existing chosen voting system for the SINGLE-WINNER election is a variant of the Schulze method.

• Equal ranks: A valid ballot may be allowed to express equal support for more than one candidate.
• Over 2 ranks: A ballot should be able to express more than two levels of support/opposition for different candidates

Compliance of current systems for single-winner election given mathematical criteria set and ballot requirements

Part 3: The Schulze method for single-winner election

The Schulze method for single-winner election

Presenting the Schultz voting system

Each ballot lists all the candidates, and each voter ranks this list in order of preference using numbers: the voter places a ‘1’ beside the most preferred candidate(s), a ‘2’ beside the second-most preferred, and so forth.

In addition, variant formats exist, in which single-winner election allows each voter to:

• give the same preference to more than one candidate to express indifference between candidates.
• use non-consecutive numbers to express preferences but even though this has no impact on the result of the elections, the mindset is set up for a multiple-winner election voting system where the distance between candidates has an impact. In the Schulze method, since only the order in which the candidates are ranked by the voter matters, it remains insensitive. In fact, for the voter, a cardinal score is given and then transformed to a ranked ordered ballot by the machine. So, in the voter’s perspective, there is no change in his way to vote given the type of election (single or multiple-winner).
• consider candidates unranked. When a voter doesn’t rank all candidates, then this is interpreted as if this voter (i) strictly prefers all ranked to all unranked candidates, and (ii) is indifferent among all unranked candidates.

The output of the Schulze method gives a ranking of candidates. Therefore, if several positions are available, the method can be used for this purpose without modification, by letting the k top-ranked candidates win the k available seats. However, in a case of a variant format of multiple-winners for proportional representation, the Schulze STV method was developed.

Virtualia will consider this variant for multiple-winners election but as it misses a certain number of important criteria, another method will soon be proposed to replace the Schulze STV method for proportional representation.

Experimental criteria to decide between voting system for the single-winner election of the SCHULZE METHOD VARIANT

• Comparison: For the variant voting system for a single-winner election, we can compare it to one of the most robust systems — the Schulze method — by simulating a large number of virtual elections on a computer and comparing them in practical terms. Such investigations will be used in case we cannot prove mathematically that the given a priori improved system does or does not satisfy the given mathematical criterion set. However, these results being sensitive to the parameters of the model used to generate virtual elections, they can be biased either deliberately or accidentally.
• Bayesian regret: The expectation value of social regret defined as the expectation of the difference between the maximum possible ideal social utility minus the actual utility[6], has to be minimized.
• Simulated elections in a two-dimensional issue space can also be graphed to visually compare election methods: visit http://zesty.ca/voting/sim/.
• Simplicity. How much information needs to be carried on the central authority and chances of bad counting?

How our Schulze method works

Think of the Schulze Method as a tournament where the winner must defeat its opponents in each head-2-head game.

• To determine who wins each game of the tournament, we look at the ballots that the voters cast. It’s a lot faster than asking the voters to come back and vote for each game. If 20 people preferred A over B and 10 people prefer B over A, then A wins that game.
• To be thorough, the winner must defeat every other candidate, not just a few up a tournament tree. Because we already have the ballots to determine each game’s winner, time isn’t a constraint here and we can take our time to be careful.

Example of a ballot from the user perspective:

• The user specifies its preferences among stars (rating of 1–5 if less than 5 choices, up to 10 for reasonably being able to measure intuitively the user’s honest preference for a candidate). We simply add a star for each additional candidate and limit it to 10 whatever the number of additional candidates after 10. This is because it is hard to make truly an honest judgment with marks above 10 degrees.

The following preferences are inferred from this ballot. The number of stars isn’t important. Only the wins or losses are.

Then we aggregate the preferences with the other ballots.

The connecting lines represent inferred one-on-one games (comparisons) between the connected candidates. Look at the connecting line between A and B. On the top left side, you see the number of voters that prefer A over B. On the top right side, you see the number of voters that prefer B over A. 1 means the preference winner of the side.

Inside the algorithm logic[7]

Procedure & concept:

• We note d[X, Y] the number of voters who strictly prefer candidate X to candidate Y.
• We call path of strength s the link from candidate C(1)= X to last candidate of the chain C(n)=Y, going through all other candidates, with for all candidates i from 1 to n-1, d[C(i),C(i+1)]>d[C(i+1),C(i)] (i.e. candidate i is better than candidate i+1) and d[C(i),C(i+1)]>=s.
• s[X, Y] is the strength of the strongest path from candidate X to Y, where s is at its maximum value.
  In case of no path from X to Y, s[X, Y]=0
• The winner W is such that s[W, X]<=s[X,W] for every other X candidate.
• The definition of a Schwartz set, as used in the Schulze method, is as follows:

✉ An unbeaten set is a set of candidates of whom none is beaten by anyone outside that set.

✉ An innermost unbeaten set is an unbeaten set that doesn’t contain a smaller unbeaten set.

✉ The Schwartz set is the set of candidates who are in the innermost unbeaten sets.

• In case of ambiguity resolution, the Schulze method operates as follows to select a winner (or create a ranked list):

1. Calculate the Schwartz set

2. If there are no defeats among the members of that set, then they (plural in the case of a tie) win and the count ends.

3. Otherwise, drop the weakest defeat among the candidates of that set. Go to 1.

• A python implementation: https://github.com/bradbeattie/python-vote-core

Example

Many examples are explained on the web, one good example can be found at http://wiki.electorama.com/wiki/Schulze_method

In this example, 45 voters voted among 5 candidates.

First, we list all number of votes for each preference combination of the candidate. Imagine we get 5 ACBED, 5 ADECB, 8 BEDAC, 3 CABED, 7 CAEBD, 2 CBADE, 7 DCEBA, 8 EBADC.

A matrix of pairwise preferences has then to be computed first. We just sum up all voters that prefer X to Y. That gives d[X, Y].

Then we identify the cells with d[X,Y]>d[Y,X] (noted in red).

Now the strongest paths have to be identified. A directed graph can help visualize the solution.

Simply read for each row, the cell with the strongest value, and determine the column position. Then from the corresponding row position, find the strongest cell value and identify the corresponding column. Repeat the procedure till to get the final candidate. For instance, to go from candidate C to D, at row d[C,*] 29 is the strongest cell value, corresponding to candidate B. Then from d[B,*] the strongest value is 33, corresponding to candidate D. The smallest value of the chain is then 29. For C to E, there is a direct strong path as highlighted in red (cell value 24).

With such a process, we identify the strength of the strongest path matrix.

Now we determine the output of the Schulze method.

For each pair-wise cells [X,Y] and [Y,X], we identify the strongest value cell (in red), hence whether candidate X is better than Y.

In the example, A>B, B>D, A>C, C>B, E is stronger to anyone else. So E is the winner with the final ranking being E>A>C>B>D.

Complexity and efficiency

In reality, what happens, is that the algorithm looks for the strongest path of preference order. We list all possible voting order preferences and then we simply count the number of voters of each specific voting order.

The only complexity is to compute the strongest path known as the widest path problem. There are many ways to tackle it in the literature.

The second problem to deal with is how to handle ties (especially when allowing the users to have ties in their preferences as we set it up). Then either choose a random voter as proposed originally by Schulze himself or follow a procedure consisting of 3 steps (draw the complete directed graph with all candidates, then delete all candidates, not in the Schwartz set (i.e., any candidate who cannot reach all others) then by deleting the weakest link one by one, the remaining candidate is the winner.)

There is an efficient algorithm, that has running time O(C³) where C is the number of candidates[8]. The following pseudo code is:

for i from 1 to n, for j from 1 to n,
if (i <> j) then if (d[i,j] > d[j,i]) then s[i,j] := d[i,j] else s[i,j] := 0
for i from 1 to n, for j from 1 to n,
if (i <> j) then, for k from 1 to n, if (i <> k and j <> k) then s[j,k] := max ( s[j,k], min ( s[j,i], s[i,k] ) )
for i : = 1 to n winner[i] : = true
for i : = 1 to n for j : = 1 to n if ( i <> j ) then if ( s[j,i] > s[i,j] ) then winner[i] : = false

Satisfied criteria by the Schulze

• Mutual majority criterion
• Monotonicity criterion
• Pareto criterion
• Condorcet criterion
• Smith criterion (a.k.a. Generalized Condorcet criterion)
• local independence from irrelevant alternatives
• Schwartz criterion
• Plurality criterion
• the winner is always chosen from the Immune set
• the winner is always chosen from the CDTT set
• Minimal Defense criterion
• Strategy-Free criterion
• Generalized Strategy-Free criterion
• Strong Defensive Strategy criterion
• Weak Defensive Strategy criterion
• Summability criterion
• Independence of clones
• Neutrality of Spoiled Ballots
• Independence of Smith-dominated Alternatives

However, it violates the following criteria:

• Participation criterion
• Consistency criterion
• Invulnerability to compromising
• Invulnerability to burying
• Favorite Betrayal criterion
• Later-no-harm criterion

Part 4: About Schulze STV method for Multiple Winner voting system

A Single Transferable vote by rank voting, the SCHULZE STV method

Proportional representation systems are much less susceptible to tactical voting systems than single-winner systems.

STV method is a voting system that is designed to achieve proportional representation via rank voting. It is a method about surplus to be distributed among remaining candidates once one of the candidates has been elected. Under STV, a voter has a single vote that is initially allocated to his most preferred candidate and, as the count proceeds, candidates are then either elected or eliminated. The vote is then transferred to other candidates according to the voter’s stated preferences, in proportion to any surplus or discarded votes. The exact method of reapportioning votes can vary[9]. However, STV fails to achieve independence of irrelevant alternatives (like most other vote-based ranked systems) and monotonicity. This means that it is sometimes possible to benefit a candidate by ranking them lower than one’s true order of preference or to harm a candidate by ranking them higher. This isn’t the case for the Schulze STV method. In addition, the method has several advantages compared to standard STV methods:

• From the point of view of the voter, the Schulze STV method is no more complicated than traditional forms of STV. Under both systems, the ballot paper is the same and voting occurs by ranking the candidates in order of preference.
• Schulze STV is resistant to vote management (where a party instructs its voters not to rank a popular party candidate’s first choice).
• It is also resistant to free riding in that parties who do not participate in vote management will not be at a disadvantage. Schulze STV does not have polynomial runtime.
• They are many on the shelf’s implementation code.

The Schulze STV Method is described by Martin Schulze in the 2011 paper “Free Riding and Vote Management under Proportional Representation by the Single Transferable Vote”[10].

Implementation

Some methodology can be found here[11].

A python code can be found at https://github.com/bradbeattie/python-vote-core/blob/master/pyvotecore/schulze_stv.py

Free web implementation tools can be found at https://modernballots.com/

Failure

Schultze STV method fails the participation criterion, the later-no-harm criterion, and the later-no-help criterion. It can also be vulnerable to Hylland Free Riding.

Conclusion of part 4

We have to consider another solution for multiple-winner elections. That is what we are discussed in the next sub-annex.

Part 5: Toward a 2-round truncated, weighted, capped range voting system for multiple winners?

Understanding the voting system for multi-winner election (i.e., proportional representation)

Basic concepts to grasp:

• Benefits of weighted methods: still used today, not all voters have the same weight
• Range voting: individual preferences are more closed to the true panel of the sentiment of the voter
• Truncated median (a form of majority judgment)
• Utility voting

Properties:

• The method implemented should be as generic as possible, so working well in a corporate environment, government decision-making process, at individual group levels (private or public), and any formative groups of an entity.
• It should provide the best general view of the sentiment of each individual preference.

Starting with weighted voting systems

This type of voting system was used by the Ancient Rome assemblies but today it is used in shareholder meetings, or at a supranational level such as the European Council.

It is based on the concept that not all voters have the same amount of influence over the outcome of an election (hence the utility voting concept behind). In the long-term Virtualia voting model, we believe that the most contributive entities that work for the general interest of the community should be awarded more weight than a new joiner or the worst entity in the platform.

A weighted voting system is based on three parameters: the players, the weights, and the quota.

• The voters are the players in our case.
• The weight attached to a player is the number of votes he controls.
• The quota is the minimum number of votes required to pass a motion between 50% of the total number of votes and 100% of the total number of votes.

We can limit the voter power with the following:

1. No single entity can have more than 50% of the votes (or the minimum pass rate). This would lead to dictatorship or complete control. The same happens if one could control or influence indirectly more than the minimum pass rate.

2. No veto power. Veto power is defined in the case where the vote of the entity is necessary to pass a motion and without its vote, the motion cannot pass. There are two solutions, either wait for more voters to allow voting to be opened, or wait after a certain period, then have its vote weight truncated such as it loses its veto power.

Toward a CAPPED weighted voting systems

We measure the power of the voter via either the Banzhaf power index or the Shapley–Shubik power index. The two power indexes often come up with different measures of power for each player and yet neither one is more accurate. Thus, which method is best for measuring power depends on the situation. The Council of the European Union is applying both measures.

• The Banzhaf measure of power is based on the idea that voters are free to come and go from coalitions, negotiating their allegiance. To calculate the power of a voter using the Banzhaf index, list all the winning coalitions, then count the swing votes. If they changed their vote from yes to no, it would cause the motion to fail. A voter’s power is measured by the fraction of all swing votes he is part of.
• The Shapley–Shubik measure assumes that an entity commits to staying upon joining a coalition. Based on Shapley value, Shapley and Shubik state that the power of a coalition is not simply proportional to its size. The power of a group coalition (or the voter alone) is measured by the fraction of the possible voting sequences in which that coalition is the deciding vote, which guarantees the passage or failure of the voting result. To understand, suppose that in another majority-rule voting body with 2 n + 1 members, in which a single strong member has k votes and the remaining 2 n members have one vote each. It then turns out that the power of the strong member is min(1, k /(2 n + 1)). As k increases, the strong member’s power increases disproportionately until it approaches half the total vote and this entity has dictatorship power. That is the reason why the Shapley value concept is critical in the Virtualia voting system.

To be as fair as possible, to counter-measure collusion, a Virtualia vote should avoid a certain percentage of voters having no power at all based on Banzahf measure and the power of the strongest entity based on Shapley value should be limited.

To implement those countermeasures, we consider that:

• The average distance between the voter size power (his fraction of all voters) and his Benzhaf power should be minimized such that its final critical value is no less than 10N times the best participant Benzhaf measure. For that, the algo recomputes the voter voting weight such that a local minimum is found. We do not intend to find the perfect mathematical solution, as there is little practical interest, time consumption consideration, and an improvement of the system is just desired, not a fully ideal workable method.
• The Shapley value of the strongest voter should be downgraded by incremental step of the weighted vote, such that its power becomes less critical. The criticality value is measured as such that the distance of its Shapley value and its size power is not more than 10N the worst participant entity measure.
• N should be chosen for both computing time practicality, fairness, reasonability, and the number of participants.

The concept of 10N, or logarithm scale, is critical in the Virtualia model. It is in certain sense a measure to avoid a high Gini coefficient in terms of power discrepancy.

Using range voting

Range voting is usually used for single-winner elections. Voters’ scores are added or averaged. The candidate with the highest aggregated score wins. It is a cardinal voting system.

It was used historically:

• In ancient Sparta, a loud form was used to elect candidates (clapometers form).
• Used today in customer satisfaction surveys, such as rating star systems.
• Used to rank items without a single winner.
• Used in sports rating systems such as gymnastics.

There are variants for multi-winner elections, such as the re-weighted range voting system to elect the 5 nominees at the Academy Awards Best Visual Effects.

It generally uses a rating ballot with forms with a 5 or 10 scoring scale.

Several forms exist like:

• Abstention allowed. Instead of giving the lowest point possible to unrated candidates, with an average rating form for rating candidates (excluding candidates with too few votes for average statistical meaning).
• To remove extremist scores, a truncated mean can be used to satisfy the independence of irrelevant alternatives (a third candidate entering the election race, that can affect previous candidates ordering).
• Other methods such as median score with the highest median score to elect the candidate to exist (Majority judgment) allow avoiding exaggerating vote score ranges. To avoid ties among multiple winners, there are some methods to break ties.

A list of benefits can be found at http://www.rangevoting.org/ including being expressive, quantitative, encouraging honesty, not strategic votes, unaffected by candidate cloning, breaking stranglehold of 2-party domination so voters get more choices, current voting machines can handle range voting, the beats-all candidates wins (Condorcet), maximizes pleasant surprise, fewer spoiled ballots, and less fraud, mathematically proposes the lowest Bayesian regret[12] among all common single-winner election methods tested, has a huge positive impact, unbiases to pro extremist and pro-centrist biases, found in nature (after severer evolutionary pressure)[13].

It satisfies well many of the properties voting systems should ideally have: expressiveness, participation, favorite-safe, clone-safe, monotonicity, remove-loser safe, precinct-countability, dumb machines usability, an extremist/centrist bias low, relative enact ability, and simplicity.

We may not agree on those properties compared to the ideal system from the Arrow theory point of view, but those are also valid points. More information can be found at https://www.rangevoting.org/CompChart.html

A video explanation can be found at http://rangevote.com/imdbvote.asp

Limitation of range voting and replacement with a 2-round range voting system

There is a list of limitations for range voting, here we provide some of them as found online.

• In most cases, the ideal range voting strategy for well-informed voters is identical to the ideal approval voting strategy, and a voter would want to give his least and most favorite candidates a minimum and a maximum score, respectively. If one candidate’s backers engaged in this tactic and other candidates’ backers cast sincere rankings for the full range of candidates, then the tactical voters would have a significant advantage over the rest of the electorate. When the population is large and there are two obvious and distinct front-runners, tactical voters seeking to maximize their influence on the result would give a maximum rating to their preferred candidate, and a minimum rating to the other front-runner; these voters would then give minimum and maximum scores to all other candidates so as to maximize expected utility. However, there are examples in which voting maximum and minimum scores for all candidates are not optimal.

• Exit poll experiments have shown that voters tend to vote more sincerely for candidates they perceive to have no chance of winning. Thus, range voting may yield higher support for third-party and independent candidates, unless those candidates become more viable than other common voting methods, creating what has been called the “nursery effect”.

• Detractors state that it motivates to rank a less-preferred and more-preferred candidate equally or near-equally.

If different parts of the voters become strategic at a significant rate, this could distort the final result and lots of regrets which must be avoided at all costs.

A voting reform advocacy group called the Equal Vote Coalition proposed a variant of range voting: using two rounds to get the winner. The first round determines the top 2 candidates and the last round is an “automatic score runoff between the two highest-scoring candidates” whereby voters rank the candidates in order of preference.

They claim that the existence of a second-round would discourage any strategic ballots and exaggeration of ratings in range voting.

Conclusion of part 5: no perfect solutions only compromises

According to a set of desirable properties, assumptions, constraints, and practical use, an ideal voting system for single-winner election used can be range voting and variants such as the truncated mean weighted range voting and Schultz method variants, or a mix of both with a two-staged election depending on the number of candidates as suggested earlier.

Some methods are easier to understand than other methods for which experts are recruited to explain how to be strategic in the upcoming election.

Large interest groups of strategic voters do not exist so making assumptions on the best voting method based on this specific case may be far from reality and not compatible with mathematical or simulations in the way the latter just consider all possible parameters.

Other considerations are the state of ignorance and the practical case to find the ideal voting system for your particular needs.

State of ignorance happens in an election where most voters do not know most of the candidates, which may be the case in such social virtual network platforms that are virtual worlds. In that case, other methods may allow playing safely by voting those who they know, and not who they do not know. They should however consider unknown candidates as the average and not 0. Range voting avoids such harmful bias while other methods could for instance.

Finally, we should consider practical voting and not what outcome would give extreme cases (e.g., 100% strategic voters) as a valid consideration to discard specific voting methods.

In any case, we should think of a model based on the assumption of honest voters and push to incentivize honesty and repudiate strategic voting.

Part 6: Choosing the right voting system — questionnaire

Green — Yes

Red — No

[1] In economics, we can define it as the state of the society where we cannot improve the well-being of an individual without deteriorating the one of another

[2] By doing this, we impact a mindset toward a more egalitarian economical system within the system as well. But without a true willing at individual scale to vote for laws that improve their welfare instead of oligarchy group that controls the legal, judiciary, media, and monetary power, there is no possibility of improvement. The mindset that requires the entities joining Virtualia to align with its conceptual moral goal may help people to grasp the concept and impact real world via such a platform.

[3] such that it is impossible to establish a link between the voter and the ballot, verifiability of the vote in the sense that it insures the ballot is well counted at the counting procedure, authenticated in the sense the right and real person is the one that has voted (no virus capable to modify the vote, double wall security), secrecy of the ballot (impossible to identify the vote of the individual, just that it has voted), hence avoiding to make the voter subject to threat.

[4] (social identity via a common social unique login, corporate ID at business level, physical & public ID to check veracity and security of the individual user via digital certificates or biological certificates (fingerprints, eye contacts))

[5] If Uber joins the platform but none of its user do, then its vote will count for only one when it participates to an election. Hence there is a high incentive to create entities at user level for its customer base so its vote gets more power. However, each user will also have its own vote power if he decides to not be represented by Uber. In case the election only concerns private election such as who can vote, like only moral entities for a specific set of decision to be taken, then the vote will be unweighted among all private moral entities of the private election group.

Today’s modern world demands everyone to have immediate and steady access to the internet, especially with the incoming 4th industrial revolution of hyper connectivity. However, internet options like DSL or cable are not available in some areas. It may hinder daily life because most aspects of our lives, including work, learning, entertainment, etc., are largely internet-based. Therefore, big tech companies like SpaceX, OneWeb, Amazon, etc., have found an alternative to land-based internet.

Before moving on to space internet satellites, let’s understand what space satellite internet is.

What is satellite internet?

Satellite internet wireless Internet was initially provided through geostationary communication satellites in space, but more and more to LEO and MEO orbits.

It does not require a DSL or cable to access the internet. Instead, there is a five-part relay system that satellites internet uses.

1. Internet-ready device

It could be smartphones, laptops, gaming systems, etc., to access the internet.

2. Modem/Router

The modem translates the data to travel between your device and satellite dish.

A router allows your devices to access the internet wirelessly.

3. Home satellite dish

The home satellite dish sends beam signals to satellites in orbits and receives information back. Its position should be precise.

4. Satellites in orbits

Satellite in geo orbit provide a two-way data communication by rotating with the planet with a consistent signal. Other projects such as StarLink or Kuiper are closer to Earth, allowing speeder connections, and less lag but requires more satellites in constellation to cover all the Earth area.

5. And the last component in the relay stem is the Network operation centers (NOC) that handle the data request

Current providers are HughesNet and Viasat.

What are the recent projects for satellite internet?

In recent years, many space internet satellites have been launched each one with better features and faster internet services. Here are some of the recent projects that are under construction:

SpaceX’s Starlink

Starlink is a satellite internet constellation that provides wireless internet access around the globe. As of 2021, the constellation consists of 1,700 satellites, and it will eventually grow to consist of thousands of satellites. These satellites are small in size and rotate in low earth orbit (LEO).

Although the internet can be accessed worldwide, the actual service is only accessed by countries that have licensed SpaceX to provide the internet in their region.

Amazon’s Project Kuiper

Amazon has started an operation named “Project Kuiper.” It is a satellite constellation in low earth orbit that aims to provide fast, affordable internet services to rural areas where broadband is not easily accessible.

Amazon plans to launch, deploy, and operate two prototype satellites named KuiperSat-1 and KuiperSat-2 for Project Kuiper. The Project Kuiper was initiated in 2019, and according to Amazon, they will launch the two satellites by the fourth quarter of 2022.

OneWeb

OneWeb satellite constellation will launch in 2022 with 648 internet satellites that will rotate in low earth orbit. It will provide wireless broadband services to people around the globe. OneWeb promises to provide fast-speed internet with up to 195Mbps. The satellites are built in collaboration with the space company branch of Airbus.

What are the pros and cons of satellite internet?

Satellite internet access has been attempted in the past with failed space satellite constellation projects such as Iridium due to costs. 30 years later, the technology has improved and the cost reduced significantly. But before you switch to satellite internet, take a look at its pros and cons.

Pros

• Internet access in rural areas with more affordable pricing
• Increasing number of international providers, promoting competition outside the generally reduced number of national licensed telecommunication companies
• Improving service with latest innovations
• Speed challenging -the traditional offering

Cons

• Theoretically affordable compared to the pricing in the past but solutions are still relatively expensive in dense urban cities
• Higher latency than the traditional offering
• Does not support VPN
• Bad weather will affect the internet speed
• Magnetic storms are of high risk for an important chunk of the satellite constellation
• Still lower maximum bandwidth speed than a fiber connection
• Potential data restriction
• A large number of satellites increases the risk of runaway space debris (also known as the Kessler syndrome) despite deorbiting procedures or robotic servicing at the end of life and automated collision avoidance capabilities
• Night sky observation pollution for astronomers and amateur observers will impact the way we look at stars for millenary

Moore’s Law doesn’t appear to be working anymore, after a rate of 80% per annum from the sixties to early 2000s, it has now slowed down to 40% and less per year recently due to two fundamental issues: the excessive subthreshold leakage currents and the increasing heat generated within the chip.

The fact that the law was sustainable up to recently, is that it was more used as a target by the industry to achieve the forecast and used in marketing for determining the obsolescence of hardware. In addition, we achieved the physical limits of miniaturizing transistors. One possible way before jumping to quantum computing is 3-dimensional integrated circuity where innovations could help semiconductor performance improve for a couple of more generations.

This slow down not only appears on the number of transistors but other metrics such as energy efficiency as well as price per computing power.

To continue scaling the processing power before quantum computing becomes practicable, optimization such as edge computing or a gradual replacement of Complementary Metal Oxide Superconductor for digital computers will be needed along with circuits, cooling system, architecture improvement. New benchmarks to compare supercomputers will be redefined such as considering lifetime usage power rather than peak or something material for the real-world expectation of efficiency. And doing so, we could see a more drastic lower number (by x50) but a possibility to continue the Moore’s Law at the expense of historical performance (Rmax used in the past, and average % of Rpeak for HPCG performance).

Today solving dense matrix problems used for the Linpack Top500 performance benchmark of supercomputers is not relevant anymore as we don’t solve that mathematical problem at that scale (think about Exascale computing power all concentrated to one task: solving a big complex dense matrix seems ridiculous and far from practical daily usage).

Discrete Event Simulation may be a better benchmark as real-world matrix problems undertake such partial differential equations in everyday use, but this would require rewriting newer methods and algorithms once CMOS architecture is replaced by newer technologies.

How do Optical Character Recognition (OCR) and Machine Learning work together?

Over the past few decades, Optical Character Recognition, also known as OCR, has become a popular phenomenon. It has widespread use in various fields where it digitizes printed text so you can use it in different machine processes after electronically editing, searching, and storing data.

The working of OCR has undergone several changes, and as of now, Optical Character Recognition uses Machine learning and Computer Vision to operate.

In this article, we discuss the working of OCR and its relationship with Machine Learning (ML), specially because this is at the center of our Virtualia Shop experience.

What is Optical Character Recognition (OCR)?

Optical Character Recognition, or OCR, is a procedure for analyzing and detecting handwritten/printed text images. Afterward, the text is converted into machine-encoded text electronically and mechanically.

Benefits of OCR

• With OCR, the conversion of physical text into digital happens with great convenience without any errors.
• Once OCR converts the hard copy into a digital one, the text can be easily edited and formatted. It eliminates the need for physical storage.
• Furthermore, the OCR-created digital documents help simplify navigating information in heaps of printed, handwritten, or typed documents.
• It is good that machines can do this overwhelming job because there is no chance of skipping through information.
• Coupled with automation, this can offer massive scalability.

How does OCR work?

Here is the working of Machine Learning-based Optical Character Recognition (OCR) technology:

a. Image pre-processing

In the first step, an optical scanner processes the physical form of the document in an image. This step removes any unwanted distortions and converts the image into a black and white image. The background is characterized by white color while the characters are black. The system also segregates different elements like tables, text, and imagery.

b. Intelligent character recognition

In the next step, with the help of ML, the dark areas are analyzed. It targets one character word at a time by using the following procedures:

• Pattern recognition

The Machine Learning algorithm examines the format and handwriting on the image to detect any resemblance with the already learned data.

• Feature recognition

However, in the case of new characters, the algorithm applies specific rules to examine them and then deduce results.

Once the ML algorithms analyze and recognize the characters, they are transformed into an ASCII code that allows further analysis.

c. Post-processing

In the last step, the AI fixes the errors in the final document. For this purpose, a lexicon is created. This post-processing phase can include further automation process.

We also include image recognition and classification to help the AI decide what field to fill in automatically.

How Machine learning-based Optical Character Recognition (OCR) is a game-changer?

As the enterprise industry expands and thrives, the volume of documents/data to be filtered has also increased. In addition, there will be many unstructured documents with various formats.

That is why template-based OCR cannot keep up with this, and we need an alternative. Here ML-based OCR steps in.

It precisely extracts relevant data from documents of unstructured formats.

With Machine learning, we can now automate this data extraction, efficiently analyze the data, and make automated decisions.

Applications of OCR

Optical Character Recognition has widespread uses. A few popular ones are:

1. Legal documentation

OCR converts important signed documents into an electronic version, making them accessible among multiple parties.

2. Banking

You can now scan the cheque you would like to deposit with OCR technology, and it will immediately analyze it to confirm the validity.

3. Word processing

With OCR, you can convert printed documents to a digital form, making them editable and searchable. ML and AI ensure the accuracy of such documents.

4. Virtualia Shop Update

With our OCR technology coupled with ML, AI, automation and 3D spatial analytics, store owners and staff can quickly update their backend database with just their phone.

An Introduction to OCR Machine Learning

Most common questions on OCR and machine learning

What is OCR?

OCR (Optical Character Recognition) is the technology that enables a computer to extract text from an image or a scanned document and convert it into machine-readable text.

How does OCR work?

OCR works by analyzing the visual features of an image or scanned document and matching it with known characters to determine the correct text. The process involves several steps, including pre-processing, segmentation, feature extraction, and recognition.

What is the difference between OCR and ICR?

OCR is used to recognize printed text, while ICR (Intelligent Character Recognition) is used to recognize hand-written text.

What are the benefits of OCR?

OCR can help save time and reduce errors by automating the process of converting scanned documents into machine-readable text. It also makes it possible to search for and extract specific information from scanned documents.

What are the limitations of OCR?

OCR is not perfect and may make mistakes, especially when the text in the image is of poor quality or has a different font, style or size. Additionally, OCR may have difficulty recognizing text in languages with non-Latin characters.

What is machine learning in the context of OCR?

Machine learning is a subset of artificial intelligence that involves training a computer model to make predictions based on data. In the context of OCR, machine learning can be used to improve the accuracy of text recognition by training the computer model on a large dataset of text images.

How does machine learning improve OCR accuracy?

Machine learning algorithms analyze large datasets of text images to learn patterns and relationships between visual features and text characters. This information can then be used to make more accurate predictions when recognizing text in new images.
