"We've been seeing some interesting devices aimed at making life easier for the blind recently, but none that have captured our attention quite like the Squibble from UK designer Andrew Mitchell. The pocketable Braille interface allows users to operate mobile phones and other technology over Bluetooth, using 779 ultrasonic motors to lift illuminated caps against a silicon cover and form Braille letters and other easy-to-understand icons. There's also audio feedback, and a grip that allows for use without having to set it down flat like other Braille readers. Pretty ingenious stuff -- and Andrew says development is \"advanced,\" so hopefully this will go from concept to real product relatively soon."^^<http://www.w3.org/2001/XMLSchema#string>
