The Virtual Laser Keyboard (VKB) online worldwide shop - now available!: "The Virtual Keyboard (VKB): How does it work?
You can use the VKB (Virtual PC Keyboard) with both your laptop and PC and with a compatible mobile device, compatible Smartphone and PDA.
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."
