Definition Edit

A head-mounted display (HMD)

monitors the position and orientation of the wearer's head and displays a view (and might generate sounds) of an artificial world from that perspective.[1]

Overview Edit

"Control signals are usually derived from the human operator's motor behavior — actions of the head, hands, feet, or speech production mechanism. . . . In the case of head-mounted displays, the interface usually includes a system for monitoring head position, and the visual images displayed to the eyes and the auditory images displayed to the ears are modified in real time according to the measured head position. By monitoring head position, the visual image seen by the user can be continually modified so that, no matter how he or she moves, the objects in the virtual world remain in stable locations, just as they would in the real world. The user is given the impression that she or he is moving about in a stable world even though the stable world is created artificially."[2]
