head mounted display
A display system built and worn like goggles that gives the illusion of a floating monitor in front of the user's face. The head mounted display (HMD) is a critical component of a body-worn computer (wearable computer). Single-eye units are used to display hands-free instructional material, and dual-eye, stereoscopic units are used for virtual reality applications. See heads-up display, body-worn computer and CAVE.
