Stereoscopic 3D: Difference between revisions

The popular View-Master stereoscope was patented in 1939, and was used for “virtual tourism”. In 1949 David Brewster suggested the use of lenses, giving rise to the lenticular stereoscope. The cinematographer Morton Heilig developed the Sensorama in the mid-1950s. It was an arcade-style theatre cabinet that stimulated all the senses. It had stereoscopic 3D display, stereo speakers, fans, smell generators, and a vibrating chair with the objective of immersing the viewer in the film. Heilig created six short films for the Sensorama. He was also responsible for the Telesphere Mask, that was patented in 1960. It was the first example of a HMD - although without motion tracking and for use with non-interactive film medium. This headset provided S3D and wide vision with stereo sound <ref name=”11”></ref>.

There are two categories of electronic S3D devices: the glasses-type mentioned before, that influence the way a user sees the image on a monitor, and devices that produce an image by themselves like HMDs <ref name=”10”></ref>.
