Interesting idea applying that to homes. Instead of the device watching/scanning out from a monitor to a keyboard surface, it could be a panel on a wall in your kitchen that recognises gestures performed nearby (like in the cubic foot in front of it).

I could imagine that learning gestures to control doors, blinds, background music, lighting and wake/sleep procedures like locking all doors, fading lights, putting devices on standby, etc.
