Create a device to “see” through walls – Clarín.com

Researchers at the Massachusetts Institute of Technology (known as MIT, for its initials in English) developed the RF-Capture device, which can “see” images of the human body and identify a person behind a wall.
The device, which will be marketed in about a year, can distinguish one person from another and even track the movement of the human hand to simulate writing in air, without the need for sensors in the body or cameras in the halls, the site reported Quartz
RF-Capture works by emitting radio signals low power can pass through a wall and bounce in the body that is the other side.; then the images are captured by the device, which combines information from multiple reflections to join the silhouette of the person.
The researchers propose that the technology can be made available for applications ranging from video games and movies to hotlines and eldercare. Today to capture movements in the film industry, for example, the actors should wear sensors and move in a room full of cameras; but the new device could track their movements, even if they are behind objects or walls.
In the case of a smart home, RF-Capture could help adjusting the heating and lighting as there are people in the room.
According to the site News MIT researchers have incorporated the technology as part of a product called Emerald, specifically designed to detect, predict and prevent falls in older people. The product was presented to the President of the United States, Barack Obama, in August during Demo Day, an innovation forum taking place in the White House.
The researchers noted that there are uses “unwanted” that could lend new product: thieves could know if a house is occupied or not.
“We want to ensure that people will not use it for evil reasons,” the site Gizmodo a researcher at MIT, Dina Katabi.
“We are working on two fronts: first designing blockers that can prevent someone from being tracked except for your own device or with its consent; and, secondly, we need to have regulations that dictate how and when the devices can be used. Privacy is always a priority, “he said.
