Wearable technology
The creation of the first virtual reality headset can be credited to Cinematographer Morton Heilig. He created a device known as the Sensorama in 1962. The Sensorama was a videogame like device that was so heavy that it needed to be held up by a suspension device.
Virtual reality
In 1979 Eric Howlett developed the Large Expanse, Extra Perspective (LEEP) optical system. The combined system created a stereoscopic image with a field of view wide enough to create a convincing sense of space. The users of the system have been impressed by the sensation of depth [field of view] in the scene and the corresponding realism. The original LEEP system was redesigned for the NASA Ames Research Center in 1985 for their first virtual reality installation, the VIEW (Virtual Interactive Environment Workstation) by Scott Fisher. The LEEP system provides the basis for most of the current virtual reality helmets available today.
