A paper released this week by MIT Media Lab and Georgia Tech researchers claims that Google Glass can detect pulse and respiration rhythms in real time. The responses were measured using a built-in gyroscope, accelerometer and camera, with no external sensors.

According to lead author Javier Hernandez, “Glass detects these physiological indicators with a very high accuracy when compared to FDA-approved sensors — both pulse and respiration had only about one beat or breath per minute of error. The data is so much richer, because people use it in their regular lives. “
