SkinTrack Turns Your Arm Into a Touchscreen for Your Smartwatch [video]

the smartwatch game has just changed


SkinTrack is a wearable system that enables continuous touch tracking on the skin. It consists of a ring, which emits a continuous high frequency AC signal, and a sensing wristband with multiple electrodes. Due to the phase delay inherent in a high-frequency AC signal propagating through the body, a phase difference can be observed between pairs of electrodes. SkinTrack measures these phase differences to compute a 2D finger touch coordinate. Our approach can segment touch events at 99% accuracy, and resolve the 2D location of touches with a mean error of 7.6mm.  The technology is not yet available for the public but due to the non-invasive, low-cost and low-powered approach it’s a strong possibility that it will integrated into future smartwatches.
