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>

The Sayre glove was the first wired glove. It was invented by Daniel J. Sandin and Thomas Defanti from an idea by Richard Sayre. Both scientists were from the Electronic Visualization Laboratory at the University of Illinois, Chicago. The glove used light emitters and photocells in the fingers. When flexed, the quantity of light reaching the photocell changed, translating the finger movements into electrical signals.<ref name=”4”></ref>

The [[VIEW]] project at NASA’s Ames Research Center was founded with the purpose of producing a VR system that allowed astronauts to control robots outside a space station. The HMD that was developed had super-wide optics (almost an 180-degree field of view).<ref name=”4”></ref>
