The new algorithm watches the people behind the wall via Wi-Fi
Wireless networks like everything and they appear wider. But even a traditional Wi-Fi-signal can be much more than we used to. RF Capture system allows you to track people's movements and postures through walls - even on the opposite side of the building - through radio Wi-Fi-router.
Developers RF Capture promise to formally introduce the system at the conference SIGGRAPH Asia 2015 to be held in a few weeks, however, the basic details of the project released now. I must say that this is not the first such development. Like its predecessor, for it requires the use of a router with special add-ons that can collect and process the reflected radio signal.
However, until now such systems could specify a maximum number of people on the wall, without distinguishing any details. RF Capture with higher resolution and can detect movement, posture, and even the position of different parts of the body. Recognizing rights and were instructed not to keep an eye on him, the system will continue to monitor all the movements of his silhouette, focusing on growth and body shape of the object of observation. According to the authors, it can distinguish between up to 15 different people with the reliability of 90%.
"The data you get from the reflected waves, it turns out quite a few, - says one of the authors of RF Capture kataba Dina (Dina Katabi). - However, we have been able to allocate significant signal through a series of specially designed algorithms remove the noise. " The developers believe that these algorithms can be applied not only to spy on people, but also in the more noble pursuit - digital cinema, "smart homes" ...
"We are working on a home security device that can automatically call the rescue when someone is in the house collapses - continues kataba. - Another example, one can imagine a system of control home lighting, entertainment systems, air conditioning that works based on your location in the house. "
