Sensorama is a simulator that gives one person at a time an illusion of reality. It is a semi-portable automatic machine that can be plugged in anywhere electricity is available. The illusion of reality is achieved by providing the viewer with a wide range of sensory information. All of this information is perfectly synchronized with the picture (aromas, wind, and vibrations change instantly). All the control information is on one piece of film. Sensorama is completely automatic. The viewer activates it by depositing a coin or pushing a button (depending on application).
