Woah, this would change many things!
Basically, Sony submitted two patents: One to beam up different screens for different users from a single 3D screen. And the other is a 3D glasses that separates the beamed up screens to the viewers so each viewer can see the screen he wants.
Things are easier to explain in the picture above.
I mean, wow, no more kids fighting over what channel to watch and one cheating from the other’s screen while playing MW2 or whatever.
