Okay, so pretty much you either hate 3D movies or you love them. And if you hate them most likely it is because of the glasses that you have to put on to watch them are annoying, distracting, and kind of silly looking. Well, soon we might be able to enjoy 3D entertainment on the big screen without having to wear glasses.
A new type of display that could eliminate the need for those extra glasses to watch 3D movies in a theater was demonstrated in a recent paper by a team from MIT’s Computer Science and Artificial Intelligence Lab and Israel’s Weizmann Institute of Science. They’re calling this new display “Cinema 3D.”
While we can already view TVs in 3D without wearing glasses, this technology isn’t available for a large scale like movie theaters. 3D TVs work by using a sequence of slits in the front of the screen, which allows you to view a different set of pixels with each eye. This creates that sense of depth that we love and know as 3D. The reason this wouldn’t work for movie theaters is because that method of 3D requires viewers to be at a consistent distance from the screen and with the size of normal theaters, that is just impossible.
Cinema 3D is actually based on a pretty simple concept: It utilizes mirrors and a unique arrangement of lenses which allows you to view a film in 3D from literally any seat. The researchers have taken into account that in a movie theater, people view the screen from different angles and have accommodated for that.
While right now Cinema 3D isn’t ready nor practical for a theater – the prototype uses fifty sets of lenses and mirrors, however, it is no bigger than a pad of paper – the team is pretty sure that one day this will be the standard in theaters.
MIT professor Wojciech Matusik stated, “We are optimistic that this is an important next step in developing glasses-free 3D for large spaces like movie theaters and auditoriums.”
