Coherent Light

Here are a couple of pics of my latest gadget, the virtual keyboard. It's a bluetooth device that interfaces with my Palm T3 and provides a quicker way of inputting stuff.
It works by projecting, using laser light, a QWERTY keyboard on a flat surface. Infrared sensors then plot your fingers as they hit the projected keys and the unit sends the keystroke to the receiving device - in this case my Palm. It's a lovley complicated solution to a mobile computing problem. In the long run, it'd be far easier to hook up a wired folding keyboard, or even a regular bluetooth wireless keyboard. But where's the fun in that? It's a laser, for goodness sake. And anything with a laser (preferably visible) is cool in my book. Incidentally, it is available in the UK from Expansys .
