[AaronBurns]

We can project light from a keyboard and a screen and use a laser pointer to control the entire computer while you sit or lay down any where in the room. A completely no touch system!
Every projected object and selection (screen and keyboard) responds to the laser pointer and single hand-held pointer controls on the projection. You can project it all too a darkened ceiling or wall or carpet.

Reward: A step plausible beyond, not yet realized...realized. Just "Google" it and see...
