[[Ivan Sutherland]] created the first headset with graphics that came from a computer, called "[[A Head-Mounted Three-Dimensional Display]]." Beforehand, there was the [[Philco headsight]], which used a live analog camera feed and a motion tracker.

Ivan Sutherland and Bob Sproull created the Sword of Damocles, an HMD that was held by a mechanical arm mounted on a ceiling. The gadget was connected to a computer and displayed simple wireframe graphics to the user. The arm tracked the user’s head movements but was difficult to use. The contraption was also too heavy and bulky for comfortable use.<ref name=”1”></ref><ref name=”4”></ref><ref name=”6”></ref>
