What is Virtual Reality ?

Virtual reality is, plainly speaking, Seeing, hearing, smelling, testing, feeling an imaginary world, rather than the real one. The imaginary world is a simulation running in a computer. The sense data is fed by some system to our brain.

A computer generated multi-sensory information program which tracks a user in real time.

Virtual Reality In Military

United States: The military used it as flight simulators to train pilots.

Virtual Reality In Medical

The medical application of VR was stimulated initially by the need of medical staff to visualize complex medical data, particularly during surgery and for surgery planning, and for medical education and training.

Virtual Reality Systems

VR Systems can be divided into three groups

non-immersive systems (like workstations)See information about the real world, presented via computer - location based services, GIS .

hybrid systems (graphics on top of real world) also called: Augmented reality systems Stay in real world, but see simulated objects

immersive systems (like HMD or CAVE) See simulated world and "be" in that simulated world

Immersive systems (CAVE)See simulated world and "be" in that simulated world

The CAVE (Cave Automatic Virtual Environment) provides the illusion of immersion by projecting stereo images on the walls and floor of a room-sized cube.

Several persons wearing lightweight stereo glasses can enter and walk freely inside the CAVE.

Advantage and Dis advantages Of V.R

Training Risk-free experience Experiencing things you

wouldn’t normally be able to experience

Entertainment; fun, artistic expression.

Disengagement with real world.

VR replacing reality. People preferring VR to

reality. Difficulty of

distinguishing between virtual and real, ‘false realities represented in VR.

Possible impacts on real body
