MIT developes device that can see people through walls

A device that detects people using radio
frequencies — even through walls — has been
developed by researchers at the Massachusetts
Institute of Technology's Computer Science and
Artificial Intelligence Lab.
The MIT team touts multiple uses for the new
technology if it can be improved, including the
ability to control devices in other parts of a house or
office with body movements. It can distinguish
between 15 individuals with 90 percent accuracy.
