Could other technology replace current 3DTV's?

well, that technique has a serious flaw .. how do you create the same effect for several viewers at once? the screen has to adjustable to 4 or more people for that to become mainstream tech

I mean, you can see it if another person's head is tracked, but then it's not better than 3D now.

by the way, apart from that it needs:
- fast cameras (I think at least 240fps)
- a lot of processing power and very good software for headtracking with very little input lag

but I think it's less expensive to create a "real" 3D image than to adjust a TV (with motors or sth.) for several people at once to make them experience the 3D Window effect created by headtracking

edit: one method I can imagine to make it support 2 people (not more) is to use the light polarization technique, but that cuts the vertical or horizontal resolution in half and people would need to wear glasses

I remember a year or so ago watching on TV that a new TV was in development in Japan. That TV could host up to four different programs running on the same TV. It acted sort of like those pictures where if you look at them from different angles are actually different. They said ideally four people sitting at four different positions from the TV could all watch different programs on the same TV. Other TV's have also offered up to two people able to watch different programs on the same TV.  The one flaw was the audio.

Also you mention the camera needing to be fast, the Wiimote worked perfectly fine but that used LED's which would require a headset. But something like Natal for example should be more then sufficient. Now yes this TV would cost like 5-6k to buy but imagine a TV with four different view points and 4 seperate camera's that each focus on one persons head. Actually Natal is supposed to be able to do full motion capture of multiple people at a time it could perhaps even track all four.

That TV would be far more impressive then 3DTV.
