What is Virtual Reality?
 Virtual Reality means feeling the imaginary(virtual) world,
rather than the real one. The imaginary world is a simulation
running in a computer.
 Virtual reality is the term used for computer generated 3D
environments that allow the user to enter and interact with
alternate realities.
 The definition of ‘virtual’ is near and ‘reality’ is what we
experience as human beings.

History
 More than one person has been involved in the development of
this technological system.
 In 1950’s visionary cinematography Morton Heilig built a single

1. Continuity of surroundings
2. Conformance to human vision
3. Freedom of movement
4. Physical interaction
5. Physical feedback
6
Non-Immersive Virtual Reality
 Large display, but doesn’t surround the user.
7
Window on world Virtual Reality
 Desktop- based Virtual Reality involves displaying a
3-dimensional virtual on regular desktop display without use of
any specialized movement tracking environment.
