Scientists using wireless reflections, to identify the differences between people, from the other side of wall. Watch the video…
A team of researchers at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL), by using wireless signals like WiFi, can find where and who you are and even which hand you are moving, from the opposite side of a wall.
CSAIL device can see things, as height and body shape to create “silhouette fingerprints” for each person, through a wall.
By tracking the silhouette, the device can trace a person’s hand as he writes in the air and even distinguish between 15 different people through a wall with nearly 90 percent accuracy.
