Virtual reality

A computer-based technology for simulating visual, auditory, and other sensory aspects of complex environments to create an illusion of being in a three-dimensional world. The world is designed by the computer; it is viewed through a special headset that responds to a person’s head movements while a glove responds to the person’s hand movements. For example, while in a virtual room, raising one’s gloved hand will cause a virtual object seen through the headset to move upward.
