A new system developed by Professor and CSAIL Principal Investigator Dina Katabi along with her graduate student Fadel Adib could one day let us see through walls Superman style. The technology uses low-power Wi-Fi signals to track human movement and can even decipher motions behind walls.
“The system, called “Wi-Vi,” is based on a concept similar to radar and sonar imaging. But in contrast to radar and sonar, it transmits a low-power Wi-Fi signal and uses its reflections to track moving humans. It can do so even if the humans are in closed rooms or hiding behind a wall,” wrote Larry Hardesty for MIT News.
