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 reflected off bodies, their system reconstructs human bodies without cameras or LiDAR.
This technology leverages artificial intelligence and existing WiFi infrastructure to provide an alternative to cameras, overcoming their limitations. This technology and its implementation is meant to address challenges in privacy, cost and environmental adaptability. It is redefining how we view privacy, surveillance, and monitoring and brings concerns of invasive practices being implemented.
