Prototype Microsoft display could make 3D glasses obsolete

The current crop of 3D TVs are pretty neat, I guess, but they all share a common dealbreaker: those stupid glasses. Nobody wants to pay for them and nobody wants to wear them. Can 3D survive them?

It can if Microsoft has its way. The company has been working on a new lens that would allow for 3D video with no glasses necessary.

How does it work? Well, the display tracks the viewers eyes using an onboard computer. It then delivers a different image to each eye. It can even handle two viewers at once, projecting different images to each of them. The downside? It currently has a viewing angle of only 20 to 40 degrees.

Built into a computer screen, though, this could be an amazing way to play games or watch movies in 3D without needing glasses. We'll see how long it takes for this tech to make it to market.
