3D glasses could soon come to an end, as MIT researchers invents new 3D screen that allows moviegoers to watch films without using glasses.
The prototype screen called “Cinema 3D” is composed of special lenses and mirrors so viewers can watch without glasses, anywhere around the theatre.
“Existing approaches to glasses-free 3-D require screens whose resolution requirements are so enormous that they are completely impractical,” says MIT professor Wojciech Matusik.
“This is the first technical approach that allows for glasses-free 3D on a large scale.” Matusik added.
MIT’s Computer Science and Artificial Intelligence Lab (Csail) and Israel’s Weizmann Institute of Science made collaboration in publishing a paper telling how the screen works.
“Rather than attempting to display many angular images spanning the full range of viewing angles in a wide cinema, our design only displays the narrow angular range observed within the limited width of a single seat. The same narrow range content is then replicated to all rows and seats in the cinema. To achieve this, it uses an optical construction based on two sets of parallax barriers, or lenslets, placed in front of a standard screen,” the paper explains, as International Business Times reports.
The MIT researchers are hopeful that this is a significant next step in creating glasses-free 3D for large spaces, while Matusik said that it remains to be seen whether the approach is financially viable enough to scale up to a full-blown theater, as Science World Report posted.
