How an electronic wristband turns your arm into a trackpad

Caption

Researchers have developed technology that turns a smartwatch user’s forearm into a trackpad, allowing the user to scroll, zoom, and click on icons. The system uses radar to track the movement of a user’s fingers on the forearm and monitor pressure on the skin, providing the same level of force-touch detail available on laptop trackpads.
