In Brief
MIT's CSAIL has developed a glasses-free technology that allows 3D movies to be seen without glasses and without losing any resolution or quality. The technology can work with various interfaces and is likely to make 3D home viewing more popular.

The Computer Science and Artificial Intelligence Lab (CSAIL) at MIT has developed a technology that allows for watching 3D movies glasses-free at home without some of the downsides we’ve come to expect from existing glasses-free 3D options. Better still, this new tech works with any existing 3D movie.

This new method uses automultiscopic displays to convert 3D movies from their stereo format with the help of Home3D, a conversion algorithm. Home3D runs in real-time on a graphics processing unit (GPU) like PlayStation 4 or Xbox One, making previous issues with automultiscopic displays and compatibility a thing of the past. The algorithm could eventually run on embedded chips in Blu-ray players, televisions, or media streaming devices like Google Chromecast, allowing for both aftermarket and integrated options.

Another perk of the Home3D tech is that viewers can customize the depth effect they see. The tech presents even high depth scenes with a very high resolution and accuracy. So, although some people might enjoy wearing specs for the glasses-assisted 3D tech they have at home, there may soon be a much nicer, hassle-free alternative that makes 3D viewing even more popular. If James Cameron indeed comes through with his glasses-free 3D Avatar sequels, that may be the final push that fuels the future of 3D.
