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.
The majority of Virtual Reality (VR) and Augmented Reality (AR) devices are head-mounted displays. In AR, the display is usually transparent and digital information is superimposed onto real life objects. These HMDs are called Optical head-mounted displays or OHMDs. In VR, the display is not transparent and only virtual information and images are displayed in front of wearer's eyes.
Virtual Reality HMDs
Large Field of View
VR HMDs have displays with large field of view (FOV) that comprise the entirety of the user's vision. With both eyes, humans have about 180 degrees FOV. The display of a VR device should cover as much of the vision range as possible. A large FoV is important to create immersion for the wearer.

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.
