I only say interactive whiteboard because that's what it would become, not because that's what I get originally. I am not like, getting a smartboard.

Essentially it's like this... I'm going to have a normal projector pointing at an everyday, normal white wall without any special effects. The projector is hooked up to a computer of course and is showing the computer's image on the wall. The infrared camera is pointing at the wall (the projected image) and it reads any infrared light and the software translates that to mouse movement (in this way you can use a tiny IR LED writing on the wall to create an "interactive whiteboard," but that's not what I'm attempting here). So basically the laser will hopefully allow me to be far away and project a concentrated dot onto the projection. Get it?
