The Sensorama is an early example of immersive multimedia technology that was developed in the late 1950s by filmmaker and inventor Morton Heilig. It was one of the first attempts to create a multisensory experience that combined elements of film, sound, and physical sensations to provide a more immersive and interactive viewing experience.

The Sensorama was essentially a large, cabinet-like device that a person would sit inside. It featured a stereoscopic 3D display, stereo speakers, and various sensory elements such as a vibrating seat, fans for wind effects, and even scent emitters to create a more realistic and engaging experience. Users could watch short films that were specifically designed for the Sensorama, and as they watched, they would also experience corresponding sensory effects that matched the on-screen action.

While the Sensorama was an innovative concept and ahead of its time, it was never widely adopted or commercialized. Nevertheless, it is considered a precursor to modern virtual reality (VR) and immersive entertainment technologies, as it laid the foundation for the idea of using technology to create more immersive and interactive experiences for audiences.
