Device Can Read Emotions By Bouncing Wireless Signals Off Your Body

Emotions can be tricky enough for humans to read, let alone machines, but a new system can predict people's feelings with 87 percent accuracy by bouncing wireless signals off them, researchers say. The setup, dubbed EQ-Radio, analyzes the signal reflected off a subject's body to monitor both breathing and heartbeat. Using a device smaller than a Wi-Fi router, researchers at MIT were able to monitor a person's breathing and heartbeat wirelessly.
