The Heart Rate assessment measures the pulse of a participant using the smartphone camera and flash. The assessment monitors blood flow through the tip of the finger over the course of 20 seconds and provides quality control warnings if a heart rate is not detected. Data collected from this assessment includes heart rate estimation, a running confidence score, and summarized video pixel intensities.
