Watch 3-D movies at home, sans glasses
While 3-D movies continue to be popular in theaters, they haven’t made the leap to our homes just yet — and the reason rests largely on the ridge of your nose. Ever wonder why we wear those pesky 3-D glasses? Theaters generally either use special polarized light or project a pair of images that create a simulated sense of depth. To actually get the 3-D effect, though, you have to wear glasses, which have proven too inconvenient to create much of a market for 3-D TVs. But researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) aim to change that with “Home3D,” a new system that allows users to watch 3-D movies at home without having to wear special glasses. Home3D converts traditional 3-D movies from stereo into a format that’s compatible with so-called “automultiscopic displays.” According to postdoc Petr Kellnhofer, these displays are rapidly improving in resolution and show great potential...
