Why is that man wearing sun glasses indoors? They aren't sunglasses, those are 3D goggles. While none of the companies demonstrating 3D-capable TVs were prepared to make any projections as to when product might actually hit the retail shelves, it was a common attraction at a good number of exhibits.
The TVs can be used normally, and at the flick of a switch, the frame rate is split sending separate frames to each eye to create the 3D effect. The beauty of this design is you can use existing software and movies. The last thing we would need is yet another new media format. Oh, and by the way, the effect is pretty cool with driving games, creating a realistic sense of "being there".
