Laptop touch screen from webcam? Answered

I had a quick look around for something like this, but couldn't find anything.

Place some kind of mirror / lens / prism over the webcam at the top of my laptop's screen so that it can register the screen itself + software to track finger(s) touching the screen. = (multi)touch screen.

The angle would be easy, figuring the distance of the finger from the camera would be trickier...

You might not get amazingly good resolution, but it should be enough for iPhone type scrolling sweeps and simple button pushing etc.

Thoughts?

Take a look at a program called community core vision.
