There are two major types of display: World fixed display and head-fixed display. A world fixed display exists in the world, like a laptop, a TV, or a smartphone. A head fixed display is mounted to the head, meaning when you turn your head it stays in front of your eyes. Head fixed displays include VR headsets and the google glass and vuzix devices.
