MIT Engineers Invent A Cameraless Tracking System That Sees Through Walls

WiTrack, a prototype designed at MIT, can track your movements anywhere in a house, even through walls.

In the Iron Man movies, Tony Stark never has to worry about interacting with JARVIS, the artificial intelligence in his "smart home," by making sure that he stays in proper view of a motion-tracking camera. He just walks anywhere he damn well pleases, barks orders and waves his hands, and JARVIS is somehow able to track him. Now a team of engineers at MIT has created a system called WiTrack which could offer the same kind of experience. It's a 3-D motion-tracking system like Kinect, except it doesn't use cameras and it can track you anywhere in a house, even through walls.
