Multi touch screen improvement(?) idea.

I don't know if this has been suggested or not.

If you take the mini projector covered at the CES show (Episode 421) and used it with the multi touch screen made in Episode 404 you could project the image from inside the box onto the back of the touch-screen.

The projector would have to be placed in the centre to create a flat/even image and the camera would have to be placed as close as possable to the projector.

Some problems that I can see are that the camera for the touch screen needs to be able to see the finger tips which might be made difficult due to the light from the projector.

Also the angle that mini projector projects at may not be wide enough to fit into a box of a practical size
