AR- EyeGlasses

Glass is a wearable computer featuring a head-mounted display in the form of eyeglasses. The  glasses function as a hands-free smartphone, letting users access the mobile internet browser, camera, maps, calendar, and other apps by voice commands.
AR displays can be rendered on devices resembling eyeglasses. Versions include eyewear that employs cameras to intercept the real world view and re-display its augmented view through the eye pieces and devices in which the AR imagery is projected through or reflected off the surfaces of the eyewear lens pieces.

A head-mounted display (HMD) is a display device paired to the forehead such as a harness or helmet. HMDs place images of both the physical world and virtual objects over the user's field of view. Modern HMDs often employ sensors for six degrees of freedom monitoring that allow the system to align virtual information to the physical world and adjust accordingly with the user's head movements. HMDs can provide VR users mobile and collaborative experiences. Specific providers, such as uSens and Gestigon, are even including gesture controls for full virtual immersion.
