Your smartwatch touchpad is really small for you? You think you have many useful apps on your smartwatch but there is no way to use them properly because of the screen size. And all of us know that it couldn’t be bigger, not for a smartwatch.

The company Future Interfaces Group has the solution: SkinTrack. As they describe on the official website: “SkinTrack 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. SkinTrack measures phase differences to compute a 2D finger touch coordinate. Our approach is compact, non-invasive, low-cost and low-powered. We envision the technology being integrated into future smartwatches, supporting rich touch interactions beyond the confines of the small touchscreen”.

The researchers found that they could determine when the finger was touching the skin with 99 percent accuracy and they could resolve the location of the touches with a mean error of 7.6 millimeters. The system has some limitations. Keeping the ring powered up is a challenge. Signals also tend to change as the device is worn for long periods, thanks to factors such as sweat and hydration and the fact the body is in constant motion. But the device is safe, with no ill effects.
