Wi-Fi signals are typically information carriers between a trans-mitter and a receiver. In this paper, we show that Wi-Fi can also extend our senses, enabling us to see moving objects through walls
and behind closed doors. In particular, we can use such signals to identify the number of people in a closed room and their relative locations. We can also identify simple gestures made behind a wall,
and combine a sequence of gestures to communicate messages to a wireless receiver without carrying any transmitting device.

Des chercheurs du MIT sont parvenus à construire un dispositif/logiciel capable d'identifier des corps mouvants dans une autre pièce dont les portes sont fermées. Il peuvent ainsi identifier le nombre de personnes, leurs positions ainsi que leurs gestes dans cet espace. Cela repose sur du Wi-Fi MIMO.
