“A new technology … may give users a new way of providing … interactivity … a gesture recognition system that can control a wide range of devices.
“The ‘AllSee’ system uses wireless signals for both power and gesture recognition. Sensors in the system read changes in the signals created by the gestures, and transforms them into specific commands. The UW team’s prototype is now using TV and RFID (radio frequency identification) signals for showing off AllSee’s capabilities, but they hope one day to use WiFi signals as a source of power.”
