Cinematographer Morton Heilig created Sensorama, the first VR machine (patented in 1962). It was a large booth that could fit up to four people at a time. It combined multiple technologies to stimulate all of the senses: there was a combined full-colour 3D video, audio, vibrations, smell and atmospheric effects, such as wind.

This was done using scent producers, a vibrating chair, stereo speakers and a stereoscopic 3D screen. Heilig thought that the Sensorama was the "cinema of the future" and he wanted to fully immerse people in their films. Six short films were developed for it.
