It feels like you're taking a 3D interaction and smashing it back down into 2D. While neat, it's unlikely to catch on.

What would be amazing is using this to interact with a 3D display system. Not the 3D in a box that you get with TV's, but something closer to what we often think of holograms.

Holograms are probably a ways off (though they are doing interesting things with targeting light at retinas).

The Occulus Rift though (as others have mentioned) may be able to do something truly awesome when paired with an interface like this.

Both devices are incredibly exciting. If they manage to mesh up...

Good point. I think this would complement the Occulous rift perfectly. You could actually use your hands to interact with the enviroment with centimeter precision! Let's hope someone thinks of this.
