“Even before the Sensorama, however, Heilig had worked on another patent that would have also proved influential on future virtual reality designers, had they heard of it: the Telesphere mask, awarded a patent in 1960 under the name, “Stereoscopic-Television Apparatus For Individual Use.”The Telesphere mask was a sort of head-mounted version of the Sensorama that would allow for wrap-around views, stereo sound, and air currents that could blow at different velocities or temperatures, and could carry smell (Heilig, 1957). The Telesphere was the first patented head-mounted apparatus designed to convey virtual views to the user, predating Ivan Sutherland’s influential “Head-Mounted Three-Dimensional Display,” nicknamed the “Sword of Damocles” by half a decade. The mask was built as a prototype, but Rheingold surmised in 1991 that, “If it had not been for the vicissitudes of research funding, Morton Heilig, rather than Ivan Sutherland, might be considered the founder of VR."
