How wireless “X-ray vision” could power virtual reality, smart homes, and Hollywood

(MIT News) 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 movements as 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.

Researchers say the technology could have major implications for everything from gaming and filmmaking to emergency response and eldercare.
