'''Head-mounted display''' or '''HMD''' is a [[device]] worn over your head. It features a display in front of one or both of your eyes. The display streams data, images and other information in front of the wearer's eye(s). Certain HMDs such as [[Oculus Rift]] or [[HTC Vive]] have displays over both of their users' eyes. Others like [[Google Glass]] only have a display over one of the users' eyes.

HMDs in the future will be able to track translational motion and perform positional tracking.

Augmented Reality HMDs also known as Optical head-mounted displays or OHMDs. The displays of these devices are transparent. They allow users to see through them while projecting images and information in front of the users' eyes.
