It seems that technology is more evolved than we think. Everything indicates that scientists have been trying to create this technology for a while and now, finally, they have succeeded. But does this technology really work or is it just speculation? Read below and learn all about how scientists developed a new technology that allows you to “see” through the wall only using Wifi.
New technology is developed by scientists
It all happened in the US state of Pennsylvania, it was there that researchers from Carnegie Mellon University got together and together they developed a method that detects the three-dimensional shape and movements of human bodies in a diverse environment, just using WiFi routers to obtain this “view through the walls”.
They explained that in order to develop the technology, DensePose was used, which is a system that has the function of mapping the pixels on the surface of a human body in a photo.
According to Vice, this system was thought and designed by researchers in London and Artificial Intelligence (AI) researchers at Facebook.
It was at that time, according to the recently published article uploaded to the arXiv preprint server, that a neural network was developed that maps the phase and amplitude of WiFi, sent and received by routers to coordinates on human bodies.
This search has been going on for some time. Scientists worked hard to reach this result. They always tried to “see” people without having to use cameras and radar.
Other researchers tried to develop the technology
In 2013, at the Massachusetts Institute of Technology (MIT), a team of researchers found a way to use smartphone signals to see through walls. After five years, another MIT team took WiFi to try to detect people in another room and translate their movements into walking stick figures.
With the advancement of technology, it has become possible to explore and make many discoveries. The researchers, from Carnegie Mellon, believe that these signals, that of WiFi, could serve as a ubiquitous sensor.
This would only be true for normal RGB cameras and you can only sense people or their movements in a room. Finally, they said that using WiFi tends to overcome obstacles like poor lighting and occlusion that regular camera lenses face.
It seems that technology is advancing too fast, every day new discoveries are made by researchers or scientists. What remains for us is to stay tuned in the news and try to understand how everything works.
