• Resumen

  • The radio waves emitted by cellphones are reflected back to them in unique ways by hands--allowing gestures to be recognized. SideSwipe is the work of Matthew Reynolds and colleagues at the University of Washington in Seattle. It comprises an algorithm that recognizes the unique reflections created when fingers interrupt a burst of the radio waves that send information between people's phone and the cellphone mast. In tests with 10 volunteers, the program could recognize eight separate taps, four hovers and two sliding gestures with 87% accuracy.
