Wrist Sensor Turns Your Hand into a Trackpad

Ever imagined to use your hand as a touchscreen? Turn your idea come true with Kei Nakatsuma’s wrist sensor then. Based on infrared detection, the device can figure out where the user’s finger is and detects the finger’s “tap” or “click” motions to accomplish certain tasks. As it turns users’ back of hand into a trackpad, you no longer need to bring touchscreens around next time you prepare for a talking show.
