Autostereoscopy
From Wikipedia, the free encyclopedia
Autostereoscopy is a method of displaying three-dimensional images that can be viewed without the use of special headgear or glasses on the part of the user. These methods produce depth perception in the viewer even though the image is produced by a flat device.
Several technologies exist for autostereoscopic 3D displays. Some flat-panels displays have a lenticular screen. If the viewer positions their head in certain viewing positions, they will perceive a different image with each eye (one from each of the sets of lenticles), giving a stereo image. These displays can have multiple viewing zones allowing multiple users to view the image at the same time. Other displays use eye tracking systems to automatically adjust the two displayed images to follow the viewer's eyes as they move their heads.
Various manufacturers are producing autostereoscopic products, including Sharp, Philips, and other companies specialized in the area. Such products can be produced using lenticular lenses or parallax barriers.
