The technology is designed to recognize changes in the frequency of wireless signals that occur when a person moves. Known as the Doppler frequency shift, the changes could be recognized by an adapted Wi-Fi router that could be programmed to understand that a certain gesture, like a of the hand or a push of the arms, would correspond to a specific device.
WiSee, its developers claim, constitutes the first whole-home gesture recognition system using wireless signals.
Gesture-based technology is not exactly a new concept. Microsoft's XBox Kinect, for instance, uses cameras to recognize gestures, and the technology has been popularized in recent years in major Hollywood movies such as "Iron Man" and "Minority Report."
