Optical head-mounted display
- See also: Augmented Reality Devices
Optical head-mounted display or OHMD is a type of head-mounted display that projects images and allows the user to see through its display. OHMDs are used in augmented reality (AR). Unlike Virtual Reality HMDs that obscures our vision of the real world, OHMDs allow us to see our surroundings while streaming data and image overlays in front of our eyes.
Optical head-mounted display can cover only 1 eye such as the Google Glass or both eyes. Wearers can interact with the projected digital content through input methods such as voice commands, gestures and controllers.
