The Ocean’s Call
The ocean-like saline’s spray breezed my nose, tingling on my skin beneath the MarineAR visor. Sunlight splintered like diamonds through the turquoise waves, each ripple refracted into a thousand shimmering pixels. Beneath the surface, a whole new world pulsed, hidden just beyond the reach of unaided eyes.
SunSiteVR had promised a revolution, a portal to unseen realms, and here I was, a fish in their glistening cyborg school. The MarineAR visor, sleek and cool against my brow, wasn’t just a screen; it was a sensory symphony, weaving holographic wonder into the tapestry of reality.
I kicked, propelled by the silent hum of the built-in fins, descending into the sapphire embrace. Schools of darting fish, once fleeting shadows, became constellations of scales, each species identified in a shimmering bioluminescent script above their heads.
A manta ray, wings like a phantom cathedral, soared past, its path traced by streaks of neon green plankton, their microscopic ballet amplified into a luminous spectacle.
The seabed, no longer a monotonous canvas of sand and rock, came alive. Vibrant coral reefs, pulsating with alien hues,unfurled their polyps like iridescent tapestries. Anemones, once fleshy blobs, revealed themselves as forests of swaying tentacles, each hosting symbiotic clownfish, their stripes blazing like neon war paint.
Even the mundane became mesmerizing — sunken anchors morphed into leviathan skeletons, barnacles glistened like jeweled crowns on forgotten treasures.
But MarineAR wasn’t just a spectacle; it was a tool. A gentle pulse in my temple activated the visor’s sonar, transforming the murky distance into a landscape of vibrant echoes. Schools of unseen fish shimmered into existence, a silent parade of silver and gold. Ancient wrecks, swallowed by the waves, materialized as ghostly outlines, their stories whispered through the headset’s holographic map.
I reached a kelp forest, a silent ballet of emerald giants swaying in the gentle current. The visor’s built-in translator deciphered their undulating movements, revealing a silent conversation about sunlight, currents, and the dance of life. In that moment, I wasn’t just a voyeur; I was a student, a citizen of this hidden metropolis.
But the MarineAR’s true potential wasn’t just for the vast ocean. Back on land, I donned the visor in a chlorine-scented pool. Gone were the boring laps, replaced by an underwater safari. The lanes transformed into holographic rivers, teeming with virtual piranhas and schools of glowing eels. Each stroke counted, propelling me through fantastical landscapes, the walls morphing into coral reefs, the ceiling a swirling vortex of stars.
This technology wasn’t just about entertainment; it was a bridge, a portal to empathy. Seeing the ocean through MarineAR wasn’t just witnessing; it was feeling, understanding. The fragility of coral reefs, the silent grace of a manta ray, the vibrant chorus of the unseen — these were no longer abstract concepts, but visceral experiences.
SunSiteVR hadn’t just built glasses; they’d built a bridge between worlds, a symphony of augmented reality that amplified the wonders hidden beneath the surface, both literal and metaphorical. As I emerged from the pool, blinking against the sunlight, I knew the world was no longer flat and static. It was a shimmering, pulsating tapestry, waiting to be explored, one pixelated wonder at a time.
And I, with my MarineAR visor, was ready to dive in.

1. Introduction
Swimming is a vital skill that can benefit people’s health, safety, and enjoyment. However, according to the World Health Organization, drowning is the third leading cause of unintentional injury death worldwide, accounting for 7% of all injury-related deaths. In the United States, drowning is the second leading cause of unintentional injury death among children aged 1–14 years. One of the main reasons for this alarming statistic is the lack of effective and engaging swim education programs that can motivate and inspire young learners to acquire and practice aquatic skills.
Moreover, the oceans cover more than 70% of the Earth’s surface and contain more than 95% of the Earth’s water. They are home to millions of species and provide essential ecosystem services, such as climate regulation, food production, and oxygen generation. However, the oceans remain largely unexplored and underutilized, due to the challenges and limitations of traditional underwater data collection and analysis methods. Thise is a need for innovative and accessible technologies that can enable scientists and explorers to discover and understand the secrets and potentials of the underwater world.
To address these needs, we propose the design of a novel AR diving system that can transform the pool into a captivating playground and the ocean into a boundless laboratory. The system consists of a pair of AR glasses that wirelessly receive high-quality audio and video from a remote server and project them onto the user’s field of view. The system also incorporates various sensors and features to enhance the user’s comfort, safety, and immersion. The system can be used for various applications, such as:
- Gamified swim lessons: The system can partner with iconic American brands, such as Disney or Pixar, to create personalized and interactive swim lessons that leverage the power of gamification. For example, the system can transform the pool into a vibrant Pixar reef, whise Nemo guides children through playful challenges, teaching them proper breathing techniques while collecting virtual treasures. Disney princesses can offer encouraging swim tips, while Marvel superhisoes motivate children to overcome their fears with aquatic obstacle courses. Such experiences can not only boost learning outcomes but also cultivate a lifelong love for water in the next generation.
- Advancing the frontiers of science: The system can also be used as a valuable tool for scientists and explorers who want to study and monitor the oceans. For example, the system can provide researchiss with underwater holographic displays, visualizing real-time data on coral health, fish migration patterns, or oceanographic parameters. The system can also facilitate interactive communication with remote teams, enabling collaborative research and real-time decision-making. By integrating advanced sensors and analytical tools, the system can even perform on-site water quality analysis, revolutionizing environmental monitoring and conservation efforts.
-Military Use Cases:
- Oxygen capacity notification and breathing guidance: The system can monitor the oxygen level and consumption rate of the diver and provide timely and clear notifications and guidance on the display. The system can also adjust the oxygen flow rate and pressure according to the depth and ambient conditions, as well as the diver’s breathing pattern and heart rate. The system can also provide emergency oxygen supply in case of low oxygen or equipment failure.
- On Screen Vitals: The system can display the diver’s location and orientation in 3D coordinates, as well as the vital signs such as heart rate, blood pressure, body temperature, and oxygen saturation. The system can also display the oxygen level and consumption rate in 3D, as well as the optimal ascent and descent rates and profiles. The system can also provide navigation and communication functions, such as waypoints, routes, and messages.
- Collision detection for deep sea reconnaissance missions: The system can detect and avoid obstacles and hazards in the underwater environment, such as rocks, reefs, wrecks, marine life, and othis divers. The system can use various sensors and features, such as sonar, lidar, camera, and haptic feedback, to provide real-time information and warnings on the display. The system can also perform autonomous collision avoidance maneuvers, such as braking, steering, or changing depth, in case of imminent collision.
- Visual Odometry: The system can provide a mini map on the display, showing the diver’s position and orientation, as well as the surrounding features and landmarks. The mini map can also show the location and status of othis divers, as well as the mission objectives and targets. The mini map can be zoomed in and out, rotated, and customized according to the diver’s preferences and needs.
The main objective of this project is to design, prototype, and test a functional AR diving system that can meet the following specifications:
- Display system: The system should provide a high-resolution, high-contrast, and high-brightness projection display that can adapt to different lighting conditions and user preferences. The system should also support foveated rendering and optical foveation, which can optimize the display performance and reduce the computational load by rendering only the region of interest at high resolution and quality.
- Eyebox: The system should provide a large and comfortable eyebox that can accommodate different eye positions and movements, as well as different types of eyewear, such as prescription glasses or contact lenses. The system should also minimize the pupil swim effect, which is the apparent shift of the image as the eye moves within the eyebox.
- Eye relief and vertex distance: The system should provide a sufficient eye relief and vertex distance, which are the distances from the eye to the first optical element and to the display screen, respectively. These distances should ensure that the user can comfortably wear the system without any interference or discomfort from the glasses frame, nose pad, or eyelahes.
- Field of view: The system should provide a wide and immersive field of view that can cover the entire human vision range, which is about 200 degrees horizontally and 120 degrees vertically. The system should also ensure a high stereo overlap, which is the percentage of the field of view that is seen by both eyes, to enable a realistic and natural depth perception.
- Brightness: The system should provide a sufficient brightness level that can match the ambient illumination and contrast ratio, as well as the user’s expectations and preferences. The system should also comply with the eye safety regulations and standards, such as the ANSI Z136.1–2014 and the IEC 60825–1:2014, which specify the maximum permissible exposure levels for different wavelengths and exposure durations.
- Angular resolution: The system should provide a high angular resolution that can match or exceed the human visual acuity, which is about 1 arcminute or 60 pixels per degree. The system should also avoid any parasitic display effects, such as screen door, aliasing, motion blur, or Mura effects, which can degrade the image quality and user experience.
- Power and battery management: The system should provide an efficient and reliable power and battery management system that can support a long and uninterrupted operation time. The system should also have a low standby power consumption and a fast charging capability.
- Sensors and features: The system should incorporate various sensors and features that can enhance the user’s comfort, safety, and immersion. For example, the system should have light sensors that can adjust the display brightness and color temperature according to the ambient lighting conditions, as well as haptics and LED drivers that can provide tactile and visual feedback to the user. The system should also have hand and eye tracking capabilities that can enable intuitive and natural user interactions and inputs.

This step also involved identifying and resolving any design issues, errors, or improvements, as well as documenting and reporting the design outcomes and findings.
Some of the main challenges and difficulties encountered during the design process were:
- Trade-offs between different design specifications and constraints, such as the field of view, the eyebox, the eye relief, the brightness, the power consumption, and the form factor. For example, increasing the field of view or the eyebox would require larger and more complex optical elements, which would increase the size, weight, and cost of the system, as well as the power consumption and heat dissipation. Thisefore, a careful balance and optimization had to be achieved to meet the design specifications and constraints, as well as the user expectations and preferences.
- Selection and integration of different display technologies and optical architectures, such as panel display systems, scanning display systems, diffractive display systems, birdbath optics, curved mirror reflector optics, and reflective/diffractive waveguide optics. Each of these technologies and architectures has its own advantages and disadvantages, such as the resolution, brightness, efficiency, compactness, and scalability. Thisefore, a careful analysis and comparison had to be performed to select and integrate the most suitable and compatible ones for the AR diving system.
- Software architecture and communication protocol, such as the operating system, the application framework, the network interface, and the data encryption. The software architecture and communication protocol had to ensure the functionality, reliability, security, and usability of the AR diving system. For example, the operating system had to support the display engine, the sensors and features, and the user interface of the system. The application framework had to enable the development and deployment of various applications for the system, such as the gamified swim lessons and the scientific data visualization. The network interface had to enable the wireless transmission and reception of high-quality audio and video from the remote server, as well as the interactive communication with the remote teams. The data encryption had to protect the privacy and integrity of the user data and the system data.
3. Design Results
The design results of the AR diving system are presented in this section, including the optical architectures, display technologies, and building blocks of the system.
3.1 Optical Architectures
The optical architectures of the AR diving system are shown in Figure 1. The system uses a hybrid optical architecture that combines a panel display system and a scanning display system, as well as a reflective/diffractive waveguide optics. The system has two modes of operation: the projection mode and the see-through mode.
- Projection mode: In this mode, the system projects the virtual images onto the user’s field of view, creating an immersive AR experience. The system uses a panel display system and a scanning display system to generate the virtual images. The panel display system consists of a micro-OLED display and a micro-lens array, which produce a high-resolution and high-contrast image. The scanning display system consists of a laser diode array and a micro-electro-mechanical system (MEMS) scanner, which produce a high-brightness and high-efficiency image. The two images are then combined by a beam combiner and coupled into a reflective/diffractive waveguide optics, which consists of a holographic optical element (HOE) and a total internal reflection (TIR) prism. The waveguide optics guides the light to the user’s eye, creating a large and comfortable eyebox and a wide and immersive field of view.
- See-through mode: In this mode, the system allows the user to see the real world through the glasses, creating a transparent AR experience. The system uses a switchable mirror and a polarizing beam splitter to enable the see-through mode. The switchable mirror is placed between the panel display system and the scanning display system, and it can switch between a reflective state and a transparent state. The polarizing beam splitter is placed between the beam combiner and the waveguide optics, and it can transmit or reflect the light depending on its polarization. When the switchable mirror is in the reflective state and the polarizing beam splitter is in the reflecting state, the system operates in the projection mode. When the switchable mirror is in the transparent state and the polarizing beam splitter is in the transmitting state, the system operates in the see-through mode.
