Using a wireless transmitter fitted behind a wall, computer scientists have developed a device that can map a nearby room in 3D while scanning for human bodies.
Using the signals that bounce and reflect off these people, the device creates an accurate silhouette and can even use this silhouette to identify who that person is.
The device is called RF Capture and it was developed by researchers at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL).
It has long been thought that wireless signals, such as Wi-Fi, can be used to see things that are invisible to the naked eye. (Read more from “Forget X-Rays, Now You Can See Through Walls Using WI-FI: Device Captures Silhouettes and Can Even Identify People When They’re Stood Behind CONCRETE” HERE)
