When Nintendo introduced its glasses-free 3D technology in the 3DS portable gaming system, it was an instant hit. It does have some disadvantages: battery that lasts only 3 hours and you need to hold the device at just the right distance and position. Tilt it, and the 3D effect disappears.
Now Researchers at MIT’s Media Lab have developed a new approach to glasses-free 3D, called HR3D, which solves both problems at once. If this gets to the commercial stage, it has the potential of becoming the de-facto standard and making glasses-free 3D screens (and cameras?) commonplace.
