3-D cinema will soon do away with awkward glasses

The pesky cinema glasses that viewers use to watch 3-D movies may not be very comfortable and many do not want to wear them at all. A team from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) is working on a display that allows viewers to watch 3-D movies without special eyewear. Titled, "Cinema 3-D," the display has a special array of lenses and mirrors.

"The existing approach to glasses-free 3-D viewing requires screens with incredibly high resolution, making it completely impractical," said MIT professor Wojciech Matusik in a press announcement. "This is the first technical approach that allows for glasses-free 3-D on a large scale," Matusik added. Indeed, glasses-free 3D is not new but it has not yet been used in movie theaters. "What Cinema 3-D does, then, is it [encodes] multiple parallax barriers in one display, so that each viewer sees a parallax barrier tailored to their position," MIT's website further says.

A parallax barrier is as a device placed on display to show each of the viewer's eyes a different set of pixels. The team has already tried it from different parts of an auditorium to see images of consistently high resolution. Matusik said that it is an important step towards changing the face of three-dimension in movie theaters.
