US 12,740,719 B2 · Techniques for heart rate detection

Abstract

Methods, systems, and devices for heart rate detection are described. A method may include receiving physiological data associated with the user, where the physiological data may include motion data and temperature data collected throughout a time interval via a wearable device associated with the user. The method may include determining a condition quality metric associated with the time interval based on the received motion data and temperature data. The condition quality metric may indicate a relative quality of the physiological data collected throughout the time interval for determination of heart rate measurements. The method may include sampling photoplethysmogram (PPG) data for the user via the wearable device based on the condition quality metric satisfying a threshold metric value and a timer satisfying a first threshold time duration. The method may include determining a heart rate measurement for the user based at least in part on the sampled PPG data.
