Get Ready to Ditch the Flimsy Glasses and Experience a New Level of 3D Cinema

BENGALURU: Apart from the need to wear those bulky glasses, everything about 3D cinema is spectacular in its own way. But, the good news now is that we might have to stop worrying about the glasses and experience cinema like never before. Marking the beginning of a major technological feat, researchers from the Weizmann Institute of Science in Israel and MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) have come up with an innovative solution. They have invented a screen that can help viewers to experience 3D cinema without any glasses and regardless of where they are seated in the theater. The screen is designed using multiple parallax barriers (a special arrangement of mirrors and lenses) and the technology is simply known as Cinema 3D.

“Existing approaches to glasses-free 3-D require screens whose resolution requirements are so enormous that they are completely impractical,” says Wojciech Matusik, MIT professor.

There are several solutions that focus on the principle of glass-free 3D, but they cannot be implemented at cinema level sizes. The new method considers the fact that cinema viewers have a minimal movement of their heads which is limited by their seat’s width. Based on this logical presumption, the screen is equipped with a series of slits in the front, showing a parallax barrier which is specific to the viewer’s position. Technically, Cinema 3D’s system of mirrors and lenses replicates this range of view to all seats in the theater, displaying a unique perspective of  3D content to each viewer.

The technology is still under the development phase, presenting only a minor level of the working prototype. Researchers believe that the technology will effectively develop over time, gaining the ability to display high resolution cinemas on conventional screens.
