A team of researchers at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL), together with Israel’s Weizmann Institute of Science, has created a technology that will let you enjoy a 3D movie without those annoying 3D glasses.
3D screen TVs that don’t require glasses aren’t new
These 3D TV sets make use of a “parallax barrier” to give a glasses-free 3D effect. It consists of a series of slits in front of the screen that allows each eye to see a different set of pixels, thus creating a simulated sense of depth.
However, this system is not practical to use in theaters where viewers are seated at different angles and distances. Not only this, but it also lowers the image resolution.
To recreate the glasses-free 3D experience on a large screen, the team designed a new physical projector that utilizes multiple parallax barriers rather than just one.
Called Cinema 3D, the technology allows the same 3D experience to viewers at any seat in a cinema. On top of that, this new form of viewing will also improve the picture quality as well.
The Cinema 3D screen isn’t market-ready as yet, but it’s a major breakthrough in developing glasses-free 3D for large spaces like movie theaters and auditoriums.
