Abstract: A method for motion-tolerant optical heart-rate monitoring may include calibrating an array of heart rate sensors of a handheld device by (i) evaluating, while the handheld device is being held by a user, an output of each sensor in the sensor array, (ii) selecting, based on the evaluation of the output of each sensor, a subset of sensors in the sensor array for use in detecting a heart rate of a user, and (iii) using the subset of sensors to monitor the heart rate of the user. Various other methods, systems, and computer-readable media are also disclosed.
