“University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality. Researchers have shown it’s possible to leverage Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras.
By using an adapted Wi-Fi router and a few wireless devices in the living room, users could control their electronics and household appliances from any room in the home with a simple gesture.
“This is repurposing wireless signals that already exist in new ways,” said lead researcher Shyam Gollakota, a UW assistant professor of computer science and engineering. “You can actually use wireless for gesture recognition without needing to deploy more sensors.”
