defining virtual reality using psychological concepts

Virtual reality is a computer-generated object, objects, or complete world inside which multiple people interact as if it were real. It is possible to make this definition more concrete by indicating the base-line equipment characteristics required for one to computer interaction to meet the qualifications of Virtual Reality (VR). One can specify cover of sight, extent of accuracy of the visual display, and the range of human hand, head, and body movement to which the computer behaves. However, these technical specifications will shift with further improvements in computer power and new equipment for communication between humans and computers. For these reasons, a perception-based definition based on enough involvement of human cognition provides a more consistent definition of virtual reality.

Humans interface with computing systems in various ways. Even just viewing a computer display and entering data on a keyboard is one such interaction, but human to computer interactions only attain the level of Virtual Reality if they are three-dimensional, engaging and intelligent in nature. Virtual reality is an immersive computer-fabricated construct inside which people come in contact with computer-generated things in a manner directed by minimum level of artificial intelligence that the interaction appears real.
