+ - Gesture Recognition Without Batteries->

Submitted by Anonymous Coward
An anonymous reader writes "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.

“This is the first gesture recognition system that can be implemented for less than a dollar and doesn’t require a battery,” said Shyam Gollakota, a UW assistant professor of computer science and engineering. “You can leverage TV signals both as a source of power and as a source of gesture recognition.”

This technology could allow sensors to be attached to household electronics, making it possible to interact with everyday objects using gestures and also connect them to the Internet and to each other in an “Internet of Things” world.

“Beyond mobile devices, AllSee can enable interaction with Internet of Things devices. These sensing devices are increasingly smaller electronics that can’t operate with usual keypads, so gesture-based systems are ideal,” said Bryce Kellogg, a UW doctoral student in electrical engineering."
