A TRIAL BALOON DEFINITION OF VIRTUAL REALITY?

	Virtual Reality (VR) may be defined as an interactive sensory and
control interface between a human and a synthetic or computer fabricated
environment; selected stimuli from a physically remote environment (e..g.
telerobot or telepresence); or a combination of a synthetic with real physical
environmental stimuli.

	Virtual Reality technology strives to achieve a high degree of
naturalness in the interactions (or transactions) across the human)VR
interface. Naturalness is achieved by one or more of the following means:
displays that evoke stereoscopic vision, stereoscopic sound, and other sensory
inputs; controls which rely on the physical motor movements of the human; the
temporal and spatial synchronization of sensation and control actions: and
feedabck that informs both actors (human and computer) of current states.
