While those glasses-free 3D TV's do work, there's a price for all that seating flexibility. Because the 3D image has to be generated for a large viewing angle, a lot of the clarity of the picture can get lost, and movie theaters are so large that the technology that works on TV's or gaming devices or phones can't really scale up. This new prototype, called Cinema 3D, takes advantage of the fact that in a movie theater, people are all generally sitting in fixed seats. This means that the researchers can tailor a set of images for each individual seat in the theater, creating a glasses-like effect without the glasses.
