Prototype - 3D Without Glasses, 5-meter Diagonal

Not only a 200-inch screen, researchers have built Japanese - the giant screen can display stereoscopic images without glasses, too. The principle is based on rear projection, but also solves some typical 3D problems.
The 3-D device with a visible diagonal of 200 inches (equivalent to over 5 feet), scientists from the State Institute NICT built in Kyoto. It is not only is for the record, only
