Wouldn't it be like the "Nintendo VR", but without glasses? Or I'm not understanding the patent... xD

Aaaaaand more gimmicks... Great...

Better than VR, but not by much. Hopefully Nintendo doesn't take this endeavor further than a patent filing. Just let that sucker expire.

The point is, you need the glasses to get the 3D effect, but everyone else can still see the TV clearly without glasses - it's just that, for them, the perspective changes as the one with the glasses moves. By comparison, regular 3D TVs, in 3D mode, show images that become fuzzy or downright unviewable if you're not wearing glasses. Also, no need for new hardware beyond a cheap camera and pair of glasses, neither of which involve anything more complicated than what is found in a Wiimote and a Sensor Bar (and when you strip out the rest of the contents, and have the camera of the Wiimote attached to the system by wire, the costs for it all becomes minimal).

Considering that Nintendo's big on the whole "making sure that people can play together, in large groups, etc", it's a good idea that it has taken far too long for Nintendo to progress on. They should have had a product available by 2009, after the 2007 demonstration by Johnny Lee - he should have been hired immediately, too (rather than allowing Microsoft to hire him).

EDIT: Also worth noting is that the two types of 3D are different from one another. Whereas 3D TV technology makes binocular depth, this one makes depth through perspective - moving your head creates the illusion of depth. Each one has a disadvantage - 3D TV technology doesn't work quite right when you move your head - the depth perspective distorts as the actual perspective doesn't change. This sort of 3D doesn't create any static depth - you only get a sense of depth through movement.

Which is why it would be particularly cool to combine the two effects - each approach is strong where the other is weak, and the combination would create an image that would quite simply look like real 3D (as in, like the TV is a portal to another space, rather than an image).

Metroid Prime 4 with optional headtracking mode - DO EET!!

Or what they are doing with star fox u. 

Yes, how terrible for them to try to think of new ways to play games.......  

He was hired by microsoft a long time ago.

Cheaper then buying the GameCube 3D display they never made, and then Sony ripped-off for PS3.

Nintendo said 3rd party Devs can have3D capable games on Wii U, excluding the launch titles, but with this patent, you can just play all Wii U games in 3D without a 3D TV. A lot of people still don't have an HD TV yet, including myself.
