AI turns everyday smartphone use into passive heart-rate tracking
Researchers developed Passive Heart-Rate Monitoring, a deep-learning smartphone system that estimates heart rate and daily resting heart rate from eight-second facial videos captured during normal phone use. Validated on more than 160,000 videos, the system met accuracy targets across skin-tone groups, although usable measurement rates were lower in the darkest skin-tone group and clinical use still requires further testing.
