English: This handmade prototype headset is for one of the first “virtual reality” displays ever built. Developed in 1985 by Jim Humphries and Mike McGreevy at NASA’s Ames Research Center in California, the system created a computer-generated image of what a pilot might see during an actual flight.  It was intended to test concepts of presenting visual information to pilots or astronauts. Sensors tracked the movement of the wearer’s head, and the displayed images moved accordingly. James Humphries donated this to the Museum in 1997.
