MIT researchers made a machine that can read your feelings through radio waves

Jason Dorfman/MIT CSAIL Machines can now tell how you feel, even if you put on your best poker face. Researchers at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) have found a way to detect human emotions purely through radio signals. Using a device called the EQ-Radio, which emits and captures reflected radio frequency (RF) waves, the researchers bounced waves off subjects to measure their breathing patterns and heart rates. That data was then run through an algorithm programmed to match physical factors with various emotional signifiers, which then categorized the person’s emotion as one of four states: sadness, anger, pleasure, and joy.

The researchers instructed the subjects to recall a personal experience that made them feel a certain emotion. That established a…
