Tap Tech Brings Touch To Dumb Phones 70
nk497 writes "A Cambridge-based firm has come up with a way to bring touch interfaces to phones without touchscreens. According to TouchDevice, the system uses the microphone to turn any surface on a handset into a touch-sensitive input panel by analysing sound signatures. 'For example, where icons are displayed on a non-touch screen display, you could tap on there and it would activate the application,' said founder Mike Bradley. TouchDevice believes there are two markets for the technology: firstly to augment input potential in touchcreen smartphones, and secondly as a way of adding touch to 'dumb' displays. The system should be making its way into devices by early next year."

TFA talks about doing this with exactly one pre-existing microphone, which is rather unique.
Triangulating touch position using multiple "microphones" (in this case, peizoelectric widgets mounted to the glass surface, but the concept is the same) has been done before, and isn't particularly new. (More info and whitepaper [elotouch.com].)
