Virtual reality(VR)
It is a technology which allows a user to interact with a computer-simulated environment, whether that environment is a simulation of the real world or an imaginary world The user has impression of presence in that world and can navigate through it and manipulate objects in the world Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special or stereoscopic displays
virtual environment(VE) A room with projections on all walls, floor and ceiling The users wear shutter glasses to get a 3D view of the world. The users are able to move and control the environment with some kind of input mechanism Camera Device in hand

Virtual Reality History
The concept of virtual reality has been around for decades, even though the public really only became aware of it in the early 1990s In the mid 1950s, a cinematographer named Morton Heilig envisioned a theatre experience that would stimulate all his audiences senses, drawing them in to the stories more effectively. He built a single user console in 1956 called the Sensorama that included a stereoscopic display, fans, odour emitters, stereo speakers and a moving chair.

VR Parachute Trainer
the US Navy uses an i-glassses HMD in their VR Parachute Trainer at the Naval Air Base in Pensacola. Used to train pilots, copilots and navigators, the simulator allows them to hang from a harness just a few inches from the ground while experiencing the feel of a 4,000-foot jump

Conclusion
VR introduces a new way of interacting with computers Most components required for the design of VR systems are commercially available Advances in computer hardware reduce the price and enable new applications Web is very suitable for VR applications, but the proper technology is not yet there
