Virtual Reality
Expansions :
VR - Virtual Reality.
HMD - Head - Mounted Display.
AR - Augmented Reality.
Introduction :
- Virtual Reality is the use of computer technology to create a simulated environment. Virtual Reality’s most immediately-recognizable component is the head-mounted display. Human beings are visual creatures, and display technology is often the single biggest difference between immersive Virtual Reality systems and traditional user interfaces.
- Major players in Virtual Reality include HTC Vive, Oculus Rift and PlayStation VR (PSVR).
- VR technology is a growing force beyond entertainment and an important tool in education, science, commerce, manufacturing, and more. Learn the basics and the latest from experts about how VR impacts your world.
About VR :
Virtual reality is the use of computer technology to create simulated environments. Virtual reality places the user inside a three-dimensional experience. Instead of viewing a screen in front of them, users are immersed in and interact with 3D worlds. Simulation of human senses - all five of them - transforms a computer into a vehicle into new worlds. The only limitation to a superb VR experience is computing power and content availability.
Types of VR :
- Non-Immersive Virtual Reality
- Semi-Immersive Virtual Reality
- Fully Immersive Virtual Reality
Non-Immersive Virtual Reality :-
This category is often overlooked as VR simply because it’s so common. Non-immersive VR technology features a computer-generated virtual environment where the user simultaneously remains aware and controlled by their physical environment. Video games are a prime example of non-immersive VR.
Semi-Immersive Virtual Reality :-
This type of VR provides an experience partially based in a virtual environment. This type of VR makes sense for educational and training purposes with graphical computing and large projector systems, such as flight simulators for pilot trainees.
Fully Immersive Virtual Reality :-
Right now, there are no completely immersive VR technologies, but advances are so swift that they may be right around the corner. This type of VR generates the most realistic simulation experience, from sight to sound to sometimes even olfactory sensations. Car racing games are an example of immersive virtual reality that gives the user the sensation of speed and driving skills. Developed for gaming and other entertainment purposes, VR use in other sectors is increasing.

Virtual reality (VR) is an all-enveloping artificial and fully immersive experience that obscures the natural world. Augmented reality enhances users’ real-world views with digital overlays that incorporate artificial objects.
VR creates synthetic environments through sensory stimuli. Users’ actions impact, at least partially, what occurs in the computer-generated environment. Digital environments reflect real places and exist apart from current physical reality.
In AR, the real world is viewed directly or via a device such as a camera to create a visual and adds to that vision with computer-generated inputs such as still graphics, audio or video. AR is different from VR because it adds to the real-world experience rather than creating a new experience from scratch.
How it is uses for Technology :-
The VR process combines hardware and software to create immersive experiences that “fool” the eye and brain. Hardware supports sensory stimulation and simulation such as sounds, touch, smell or heat intensity, while software creates the rendered virtual environment.
Immersive experience creation mimics how the eye and brain form visuals. Human eyes are about three inches apart and therefore form two slightly different views. The brain fuses those views to create a sense of depth or stereoscopic display.
VR applications replicate that phenomenon with a pair of exact images from two different perspectives. Instead of a single image covering the entire screen, it shows two identical pictures made to offset the view for each eye. VR technology fools the viewer’s brain into perceiving a sense of depth and accept the illusion of a multi-dimensional image.
VR Accessories :-
- VR Headsets
- 3D Mouse
- Optical Trackers
- Wired Gloves
- Motion Controllers
- Smelling Devices
Audio Mechanism in VR :-
VR strives to emulate reality, so audio is vital role to creating credible experiences. Audio and visuals work together to add presence and space to the environment. Audio cues are also crucial for guiding users through their digital experience.
Convincing VR applications require more than graphics alone. Hearing and vision are also central to a person’s perception of space. People react more rapidly to audio cues than to visual indicators. To produce truly immersive virtual reality experiences, precise environmental noise and sounds as well as accurate spatial characteristics are required.
