Researchers at the University of Washington have successfully created a prototype of a system that uses Wi-Fi — and only Wi-Fi — to detect gestures. Called "WiSee," the system cleverly measures the Doppler shifts created by human movement on regular Wi-Fi signals. That means that the system doesn't require line of sight for gesture detection and, the researchers claim, it could work with off-the-shelf Wi-Fi systems. If using Wi-Fi to detect gestures isn't wild enough, the researches claim that "The average accuracy is 94% with a standard deviation of 4.6% when classifying between our nine gestures."
What sets WiSee apart is that it's able to detect gestures in the next room, and the prototype was tested in a two-bedroom apartment to...
