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 reflect off these people, the device creates an accurate silhouette (pictured) and can even use this silhouette to identify who that person is.

X-ray vision is a staple of sci-fi films and comic books and now researchers have turned this concept into a reality.
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.

With this in mind the researchers have been developing technologies that use wireless signals to track human motion since 2013.
As part of its latest research, the team has shown that these technologies can detect gestures and body movements as subtle as the rise and fall of a person's chest from the other side of a house.

The RF Capture device transmits wireless signals that travel through a wall and reflect off a person's body back to the device.
It begins by scanning the 3D space to capture wireless reflections of objects in the room, including any human bodies.
Since only a small number of body parts reflect the signal back at any given point in time, the device monitors how these reflections vary as someone moves and walks.

The researchers said the technology could have major implications for everything from gaming and film-making to emergency-response and elder-care.
[Yes, and it will enable assassins to target individuals though walls too. Seldom do these high minded research scientists consider the evil potential for their technology, which uniformly is used for unintended purposes.]

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
The RF Capture device was developed by researchers at MIT
Wireless signals travel through the wall and reflect off the body behind it
This creates a silhouette from which body parts can be identified
Silhouettes can then be compared to a database of bodies to identify who they belong to - and it can even identify which hand their moving
