What is VR?
Virtual Reality (VR) is a computer-generated environment with and within which people can interact in a simulated real-world environment. VR encompasses a range of interactive computer environments, from text-oriented on-line forums and multiplayer games to complex simulations that combine audio; video, animation, or three-dimensional graphics; and scent. Some of the more realistic effects are achieved using a helmet-like apparatus with tiny computer screens, one in front of each eye and each giving a slightly different view so as to mimic stereoscopic vision. Sensors attached to the participant (e.g., gloves, bodysuit, footwear) pass on his or her movements to the computer, which changes the graphics accordingly to give the participant the feeling of movement through the scene. Computer-generated physical feedback adds a feel to the visual illusion, and computer-controlled sounds and odors reinforce the virtual environment. Experimental, current and envisioned uses for virtual reality include education, industrial design, surgical training, tourism and art.
