WiTrack system can see through walls of human movement




Device technology definition of human movement, such as Microsoft Kinect , slowly but surely developing in the world. But these devices can operate within sight of the object. A group of scientists from the Massachusetts Institute of Technology (MIT) has developed a system WiTrack, which can detect the movement of a person who is behind a wall or other obstacle.

Technology is based on the body’s ability to reflect radio wireless network, the accuracy of location of a person is determined with an accuracy of only 10-20 centimeters, according gizmag.com.

This is not the first development of these scientists – about a year ago they introduced a system WiVi, which determined the movement of a person behind the wall with the help of Wi-Fi signals. But as assured developers, the new system has WiTrack accuracy in the determination and can analyze 2D and 3D-space.

WiTrack system has four antennas, one of which is used for signal transmission and reception for the remaining three. Device for his work transmits a low-power signals, about a hundred times weaker signal Wi-Fi.

The project is still far from the stage of commercial production, but it looks pretty promising. In the future WiTrack can be used for fun and games, and use in control systems , “smart” home . Additionally, the system can analyze not only the entire human body, but also its individual sections. In the video below you can see how people raising their hands off the light in the next room.
