Carnegie Mellon University researchers have developed a technology that detects three dimensional shapes and movements of human bodies in a room, using only WiFi routers. By analysing radio waves ...

Scientists from Carnegie Mellon University have developed a cheap way to sense humans through walls by using two Wi-Fi routers to image a human's 3D shape and pose. The researchers outline in a new ...

Computer scientists at the University of Washington have developed a way to use a modified Wi-Fi router to detect specific gestures -- even through walls -- without the need for additional sensors or ...
