"The syn-aesthetic, immersive machine developed by Heilig in 1962 widened the Expanded Cinema to a theater of total illusion, which Heilig called the "experience theater". Built inside a booth, in which visitors could sit on a movable stool, Heilig imagined that, for the price of 25 cents, Sensorama would offer multi-sensorial impressions of a virtual, ten-minute-long motorcycle ride through New York City. Apart from seeing the film, the Sensorama user would simultaneously experience the corresponding vibrations, head movements, sounds, and rushes of wind. But Heilig was unable to commercialize his visionary prototype for a cinema of the future. In a later interview he stated: The Sensorama may have been too revolutionary for its time. He patented his invention as the Experience Theater with 3–D images in 1969, and in 1971 the Sensorama Simulator for creating the illusion of reality."
