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.
Raymond Goertz
Goertz's primary work and accomplishments revolved around the development and improvement of master-slave manipulator devices, but Goertz also devoted time to completing basic research on the degrees of freedom necessary for smooth motion by remote manipulation. He also created an initial prototype of a virtual reality device by developing one of the first head-mounted displays.
