The virtual laser keyboard (VKB) works by using both infrared and laser technology to produce an invisible circuit and project a full-size virtual QWERTY keyboard on to any surface. The virtual PC keyboard behaves exactly like a real one: direction technology based on optical recognition enables the user to tap the images of the keys, complete with realistic tapping sounds(!), which feeds into the compatible PDA, Smartphone, laptop or PC.

Maybe cooler when it is integrated into my phone or my palm, but goldawgs! This is a good idea.
