I've always wondered why they dont stick a camera on the front of it, then overlay the virtual world onto the physical world.
- Show borders of things the camera sees on top of the 3d
- Show camera view aside from your controller in the "menu/system" screen
It requires more bandwidth through USB, though, so it might not work.
(I know there is a third option, but i cannot recall what it does)
It is exposed to the devs but the quality of the camera doesn't really allow for AR experience so it's not really used.
