There are many definitions of Virtual Reality. They vary from simple phrases or complex, wordy explanations. Here are three definitions that range from layman's terms to a technical explanation.

• A cartoon that you can get into.

• An interactive computer system so fast and intuitive that the computer disappears from the mind of the user, leaving the computer-generated environment as reality.

• A computer-synthesized, three-dimensional environment in which a plurality of human participants, appropriately interfaced, may engage and manipulate simulated physical elements in the environment and, in some forms, may engage and interact with representations of other humans, past, present or fictional, or with invented creatures.
