Wireless Signals Can Detect Your Feelings With New Device
CAMBRIDGE, Mass. (AP) — What if your computer or smartphone could tell if you're happy or sad? A new device developed by researchers at the Massachusetts Institute of Technology can detect a person's emotions using wireless signals reflecting off a person's body to measure human behavior. Researchers from MIT's Computer Science and Artificial Intelligence Laboratory say their EQ-Radio device is 87 percent accurate in telling if someone is excited, happy, angry or sad. It's as accurate as an electrocardiogram monitor, which uses a sensor on the body, in measuring heartbeats. They say it could one day be used by film studios and advertising agencies to gauge audience reaction, in homes to adjust temperature based on mood, or in health care. MIT's team plans to present the work at a mobile computing conference next month.
