Bionic soldiers with X-ray vision could soon be a reality thanks to a new wireless system that uses radio waves to map people’s movements behind walls.

Researchers at the MIT-trained artificial intelligence to analyze radio signals that bounce off the human body to create a dynamic stick figure that resembles a person actions.

The so-called neural network people’s feelings, postures and movement, even of the exterior of a building or space.

MIT says the tech can be embedded in a wireless device, which would theoretically allow soldiers to connect to their combat gear such as helmets and night-vision goggles.


In the future, military personnel can use on the battlefield to “see” hidden enemies by wearing augmented reality headsets.

The researchers are now working to create realistic 3D models that map even more detailed movements. For example, the tech was able to quickly see if a person’s shaking hands.

The biggest challenge the team faced is that most of the neural networks are trained using data labeledd with the hand.

If a neural network is taught to identify cats, for example, it requires programmers to look at a huge treasure trove of images and label each one as “cat” or “not cat”.


But the radio signals constitute a larger problem if they can’t be labeled in the same way by the man.

To overcome this, the researchers gathered thousands of pictures of people doing activities, such as walking, talking, sitting, opening doors and waiting for the lifts with the help of both the wireless device and a camera.

This mixture of examples allowed the system to understand is the relationship between the signal and the stick figures of the people in the scene.

Training, the system was able to estimate a person’s posture and gestures without cameras and behind walls, the use of wireless reflections that bounce off the bodies of people.

In addition, it could accurately identify individuals on the basis of their size and way of walking.

Despite the quote from the police applications, the paper is not about the military use of the technology and instead focuses on the health care system.

It can also be used for new types of video games where the players move in a house, say the creators, and in the search-and-rescue missions to help locate survivors.

“We have seen that the monitoring of patients walk away from the speed and the ability to do basic activities on their own gives care providers a window into their lives that they didn’t have before, that can be useful for a whole range of diseases,” said Dina Katabi, who co-wrote a paper on the project.

“An important advantage of our approach is that the patients do not have to wear sensors or remember to charge their devices.”
