Researchers use wi-fi to see through walls

BOSTON: X-ray vision _ a comic book fantasy for decades _ is becoming a reality in a lab. The Massachusetts Institute of Technology has developed software that uses variations in radio signals to recognize human silhouettes through walls.

Researchers of MIT’s computer science and artificial intelligence lab established new software which uses WI-FI signals variations to recognize human appearance through the wall.

The device called RF-capture that transmit WI-FI signals and then evaluate the reflection of those signals to create a human image.
