In a slightly disturbing development for poker players everywhere, researchers at MIT are now able to use a radio transmitter to accurately measure a person’s heart rate and heart rate variability, and to figure out whether that person is happy, sad, angry, or excited. In healthcare the technology may end up being used to keep an eye on patient health and maybe to even help in diagnosing anxiety, depression, and other psychiatric conditions. Because the same techniques have already been developed to detect the breathing rate and notice people walking and falling, hospitals may one day have invisible antennas throughout the patient wards that almost magically keep tabs on everyone.
Here’s a video from MIT showing off how the technology works:
