Dubbed the ring mouse, this nifty device sports integrated speakers that pump “out ultrasonic pulses, picked up by five microphones arrayed on a piece of plywood.” Video of a similar technology after the break.

A central processor calculates the ring’s position in space based on when each microphone receives each blast of sound and then correlates this to the cursor onscreen. The ring and sensors communicate 100 times a second, so the translation of hand movement to cursor is instantaneous
