A group of scientists has developed a software capable of identifying with great precision if someone is on the other side of a wall.
The team, led by researcher Dina Katabi, of MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), created an artificial intelligence-based system capable of Identify and recreate human movements.
But how does it work and how to make sure it's not used to spy on others?
The Power of Radio Frequency
Specialists have named the software the name of RF-Pose and the technology that governs it from RF-Capture because it uses radiofrequency (RF) waves .
"We use a camera and we take pictures of people in one place, and we broadcast radio signals" I Katabi to the BBC
Gradually, computer scientists taught the machine how to "see" using several examples to identify people

Thus, the neural network can badyze the signals and generate a skeletal figure in 3D that walks, smells, runs, dances or gestures like a human, imitating the movements that the person does in this moment
MIT hopes that a few years from now, this software will help doctors identify early signs of diseases such as Parkinson's disease, multiple sclerosis or muscular dystrophy, particularly in the elderly.
The idea is to better understand the progression of ailments that affect body movements, but also to help older people to have more independence.
In fact, the MIT says his team is currently working with doctors to start applying the system in the field of medicine.
Technology is able to effectively identify a person in a row of 100 people in 83% of cases.
"You do not see the details of the person's face or fingers, but you can get an idea of the size and width of the person," Fadel Adib, one of the scientists involved in the project.
"In the future, we can see through the walls even in high definition," he added. "And probably also through the bodies of people using wireless signals."

Developing it was not easy: it took over a decade and bring together thousands of images of people on the move.
The system creates what is called "heat images" and transforms them into figures that move in space, identifying different parts of the body and showing the movements in a natural way.
Beyond medicine, the system could be used in the field of video games, entertainment or security.
But it could also have malicious applications or ethical dilemmas.
Only with consent
One of the main points for this to work was to protect the privacy of users.
"If someone wants to use this technology to monitor someone without his consent, we have a test that allows the device to check if the person has given consent," explained Katabi.
"After we separated any identifiable information and we encrypted it ".
"There must be policies that regulate the way technology is used."
Will these be the first steps of a technology that will be ubiquitous in a few years?
