Battery-free technology brings gesture recognition to all devices
27 February 2014, 5:52 pm

Computer scientists have built a low-cost gesture recognition system that runs without batteries and lets users control their electronic devices hidden from sight with simple hand movements. The prototype, called "AllSee," uses existing TV signals as both a power source and the means for detecting a user's gesture command.

I had a friend who had developed his own system of gestures, especially for those inconsiderate drivers who cut him off while driving!!
