MIT Engineers Invent A Cameraless Tracking System That Sees Through Walls

A team of engineers at MIT has created a system called WiTrack. 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. One very useful application already exists: fall detection. WiTrack can detect someone falling down with 96.9% accuracy, making it a potential boon for shoring up safety in households where elderly people are living independently.
