Have they gone too far?

WiFi has become ubiquitous with the internet and now researchers are taking it to a new level:

A team of researchers at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) has long believed that wireless signals like WiFi can be used to see things that are invisible to the naked eye.

Since 2013, CSAIL researchers have been developing technologies that use wireless signals to track human motion. The team has shown that it can detect gestures and body movementsas subtle as the rise and fall of a person’s chest from the other side of a house, allowing a mother to monitor a baby’s breathing or a firefighter to determine if there are survivors inside a burning building.

Next up? Seeing a person’s silhouette and even distinguishing between individuals.
