Have you always dreamed of controlling your TV by flailing in the next room? Researchers at the University of Washington have just the system for you: WiSee, a gesture-recognition interface that uses WiFi to control things like sound systems and temperature settings. Since WiFi signals are capable of passing through walls, WiSee can detect gestures made from neighboring rooms, breaking free from the line-of-sight method relied on by devices like Kinect and Leap Motion. Unlike those two, WiSee doesn't require an additional sensor; the software can theoretically be used with any WiFi-connected device and a router with multiple antennae to detect Doppler shifts created by movement. The prototype was tested in both an office environment and a two-bedroom apartment, and the team reported a 94% accuracy with a set of nine distinct gestures. If you watch the video, embedded after the break, you'll notice that each user performs an identifying motion prior to the control gesture. It's a trick the team picked up from studying Kinect's solution for distinguishing between specific individuals in crowded rooms. Intrigued? Head over to the source link to read the report in full.
