Virtual Laser Keyboard for mobile lifestyle

Plawa and other companies have added some nice techniques to form a mobile gadget.

A laser projects a keyboard equipped onto any opaque, flat surface. The keystrokes are then identified based on the combined input of a sensor and an invisible infrared layer. The connection to PDA, Pocket PC, Smart Phone or PC is set up via Bluetooth or serial port.

The virtual laser keyboard has been on the market since 2004 and still looks cool.
