Researchers create wild skin-touch interface for tiny smart watches

The solution to tiny touchscreens is, apparently, your skin.

Researchers at Carnegie Mellon University's Future Interface group unveiled SkinTrack, the first skin-based wearable interface that overcomes tiny smartwatch screens by turning your forearm and the back of your hand into touch and gesture interfaces.

SkinTrack consists of a signal-emitting ring that you wear on your index finger and a sensing smartwatch band.

The band has four electrodes to measure the X and Y position of the ring. Not only does it measure position, the system computes the distance from the finger to each electrode (called the Phase) and uses that information to continuously tracks the finger's motion in real time. Read more...
