Light projects a keyboard onto any flat surface, with infrared scanners which transfer your keystrokes to most wireless supported devices (yes, Bluetooth). The unit measures 90mm(L) x 35mm(W) x 25mm(D), runs of either mains or battery, has light projector intensity and sound effects control, and detects up to 400 characters per minute. Awesome!
