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.
Immersive virtual musical instrument
Early work was done by Jaron Lanier with his Chromatophoria band and separately by Niko Bolas who developed the Soundsculpt Toolkit, a software interface that allows the world of music to communicate with the graphical elements of virtual reality.
