Google Research has developed a new system called PHRM that uses a smartphone's front-facing camera to passively measure heart rate and resting heart rate. The system analyzes short video clips after face unlock events, employing deep learning to estimate heart rate with an accuracy comparable to industry standards across all skin tones. PHRM integrates these measurements throughout the day to provide a daily resting heart rate estimate that rivals wearable devices in accuracy. This research aims to increase access to cardiovascular health tracking, particularly in underserved regions, by leveraging the widespread availability of smartphones. AI
