A group of scientists and engineers working out of Carnegie Mellon University in the USA have developed an innovative new technology and system, dubbed SkinTrack, that is designed to make it possible for you to control a device by moving your finger across your skin in the vein of a touchscreen.

The device's workings are wonderfully well designed. The smartwatch in question is fitted to a strap that is embedded with electrodes. Meanwhile, one finger on your other arm is adorned with a ring that emits a special electrical signal. As this finger touches the arm that's wearing the watch, an electrical signal is conveyed -- even if the skin is covered in clothing. This system allows users to run their finger across their skin in order to perform scrolling, zooming and drawing functions.

Ultimately, the SkinTrack technology is sure to be incorporated by a variety of tech manufacturers in the years to come, as touchscreen control becomes even more convenient than ever.
