We introduce AllSee, the first gesture-recognition system that can operate on a range of computing devices including those with no batteries. AllSee consumes three to four orders of magnitude lower power than state-of-the-art systems and can enable always-on gesture recognition for smartphones and tablets. We also integrate our hardware with an off-the-shelf Samsung Galaxy Nexus phone. This enables gesture control such as volume changes while the phone is in a pocket. allsee.cs.washington.edu(via http://www.youtube.com/watch?v=tJCQZxi_0AI#t=128)
Battery-free technology brings gesture recognition to all devices
Mute the song playing on your smartphone in your pocket by flicking your index finger in the air, or pause your “This American Life” podcast with a small wave of the hand. This kind of gesture control for electronics could soon become an alternative to touchscreens and sensing technologies that consume a lot of power and only work when users can see their smartphones and tablets.
University of Washington 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.(via http://www.wired.com/beyond_the_beyond/2014/02/augmented-reality-allsee-bringing-gesture-recognition-devices/)
