Computer Hardware Terms, Glossary and Dictionary

Head-mounted display (HMD) is a headset used with virtual reality systems. The HMD usually consists of either a helmet or glasses with either one or two small LCD or OLED displays with magnifying lenses, one for each eye. The technology can be used to show stereo 3D films, stereoscopic images or interactive 3D games. Head-mounted displays may also be coupled with head-tracking devices to allow the user "look around" a virtual reality environment naturally by moving the head without the need for a separate controller.
