TRACKING SLEEPERS BY Analyzing Radio Waves Around Them

摘要

an algorithm deviseo by researchers at the Massachusetts Institute of Technology can closely monitor sleeping patterns by analyzing radio waves reflected off the human body. The software, described in a paper presented at the International Conference of Machine Learning, measures frequency changes that occur when radio waves emitted from specialized sensors reflect off a person's body. That could (et anyone analyze their sleep patterns at home without wearing smart wristbands and rings to bed.
