TI DLP’s DualView. What IS it?

We have received word of a new display technology to be demonstrated at CES. It’s called DualView, and it apparently “it allows two opponents to view their action in full screen rather than a split playing screen.” Well, if you are playing online that is not usually a problem, but same-TV deathmatch has had this problem for years in games like Goldeneye and Mario Kart, not to mention that game with that Monsieur Chief guy in it.
What do you guys think it is? Two players both get to use the whole screen. I’m going to guess it’s some kind of refractive layer that splits the image’s projection, so each player gets the whole screen, but only every other pixel or whatever. In any case, it might be awesome, and we’ll give you the whole story in a couple days.

OK, here is a guess. A single DLP chip is a black and white only system, one way to get color is by using a mechanical spinning color wheel for red green and blue and turn on the appropraiate mirrors at the appropraiate time.
Now suppose you make the color wheel so that it has two sets of red, blue and green filters, that are interleaved, the difference between the filters is that one set is polarized horizontal and the other set is polarizied vertical.
Then one player uses horizontal polarized glasses and the other player uses vertically polarized glasses. They both get full screen.
If a player tilts his head 45 degrees he will see both images equally the same.
If TI is doing this, then they also have capability to do single player 3D stereoscopic game play as well, left eye get one polarity and right eye gets the other polarity
Never heard of this before, but I think this is a good guess.
What do I win if I am right?

The TV sends an IR signal to the glasses to electronically shutter the lenses and display the appropriate video frame. For 3D, the lenses are alternately shuttered.

i have two prototypes at work we are testing in a vehicle equipped with satellite tv on-the-move. no glasses are needed. monitor is 7″ and connects using rca cables. the goal is to allow the driver to see gps information and the passenger to see video. would also be ideal in a flip down monitor that could be used by rear seat passengers to view two separate images.
