The smartwatch the displays are too small? They must have thought the same thing to researchers at Carnegie Mellon University, who developed a technology able to 'transform' the arm and skin touch controller for wearable devices.
Researchers at the aforementioned universities have developed the technology SkinTrack, which allows you to use your arm and then the skin to control a smartwatch. The display of these devices are significantly reduced compared to those for smartphones and tablets, and could not be otherwise in view of their nature, and SkinTrack tries to overcome precisely this limit.
Think about the possibility of being able to play Angry Birds on your smartwatch dragging your finger on your arm to load the slingshot. This is one of the examples shown in the video that you find at the bottom of the article and which reveals the great potential of this technology. But how it really works?
SkinTrack makes use of a ring inserted in the finger of the opposite hand to that where is the smartwatch. Its task is to send when it comes in contact with the skin, a high-frequency signal passing through the arm and that is recognized by the smartwatch sensors, so as to calculate the distance between the wearable device and the ring.
