Now the cool things about this is that in theory this will work with any device that you can connect an external camera to.  Although I know of no way to do this, lets say you have the original ipad, perhaps the algorithm will work using the back camera.  basically you are tracking 3 things, normally LEDs or other markers on your head, well. what if they were placed on a table so the rear camera can see it?  In theory that should work.  We’ll see though.  So many devices are coming out with both front and rear that it may not matter.

Check out the video below.  TELL me you do not droll over the possibilities here.

QUICK UPDATE!!  Check this hack out!  This is Rittai Kakushi e Attakoreda, a DSiWare game that makes brilliant use of the Nintendo DSi’s built-in cameras to control an in-game camera that lets the player explore a 3D diorama to find hidden objects.  Ta to Ramine Darabiha for the heads up.
