University of Washington researchers hope to revolutionise gesture-based control with AllSee, a gesture recognition technology using existing TV signals for control that's both low-power and low-cost.
“This is the first gesture recognition system that can be implemented for less than a dollar and doesn't require a battery,” UW assistant professor Shyam Gollakota says. “You can leverage TV signals both as a source of power and as a source of gesture recognition.”
AllSee consists of a small sensor one can place on electronic devices. It uses an ultra-low-power receiver able to extract and classify the amplitude changes specific gestures cause in wireless transmissions in the air, translating them into commands.
The same wireless signals also provide a power source, meaning the AllSee sensors run without need for batteries.
