Technology That Can See A Body Through Walls

Saying that technology has come a long way from where it was would be an understatement. Look around you, starting from you starting your day by going through the news on your phone, to booking a cab, ordering a meal for yourself, to getting some products. Everything in your life revolves around technology. To imagine a world where no technology prevails is genuinely shocking, to say the least.

With AI, machine learning, and other technologies turning into massive hits, I was least surprised when I heard about this new technology which can see your body through walls. A system is created by MIT (Massachusetts Institute of Technology) in their Computer Science and Artificial Intelligence Laboratory located at Cambridge, Massachusetts, the United States that makes it possible for a person to see their body through the walls. The system re-enacts your stances when you sit, stand or walk. In order to do so, the system uses RF waves for sensing your movement or where you are, thereby re-enacting your postures as a simple stick figure, which is known to be RF-Pose.

The intention of the team who created it lies in using it for healthcare, to conduct passive monitoring on a person inside a room without the usage of a camera or any other means of encroaches. The researchers confirmed that all the data that's being used by them is obtained by appropriate means through the consent of the subject being monitored. In fact, to ensure the privacy of the person is taken care of, the data is encrypted and anonymized. For the future application of this system out in the real world, the team plans to set up a consent mechanism that when a person acquires the device needs to do a particular set of moves to enable the system for monitoring the surrounding environment.

The researchers taught the neural network by playing the machine a video of a person walking next to the RF interference that they built as they moved. They then overlaid stick figures on the movement and trained the network to do the same automatically. Because RF signals are omnipresent, it was easier to use than other sensing technologies. The interesting truth is that the researchers never prepared the system to see through the walls, but it voluntarily was able to “generalize its knowledge to manage through-wall movement.
