MOTION COMPENSATION FOR OPTICAL HEART RATE SENSORS

摘要

A method for an optical heart rate sensor comprises recognizing a minimum amount of motion of the optical heart rate sensor during a testing duration and recognizing an average amount of motion of the optical heart rate sensor during the testing duration. The motion of the optical heart rate sensor is compensated for if the minimum amount of motion during the testing duration exceeds a first threshold, even if the average amount of motion during the testing duration is less than a second threshold, greater than the first threshold. The motion of the optical heart rate sensor is not compensated for if the minimum amount of motion during the testing duration is below the first threshold, even if the average amount of motion during the testing duration is greater than the second threshold.

1. A method of optical heart rate sensing, comprising:
recognizing a minimum amount of motion of an optical heart rate sensor during a testing duration; recognizing an average amount of motion of the optical heart rate sensor during the testing duration; applying compensation for motion of the optical heart rate sensor if the minimum amount of motion during the testing duration exceeds a first threshold, even if the average amount of motion during the testing duration is less than a second threshold, greater than the first threshold; and omitting compensation for motion of the optical heart rate sensor if the minimum amount of motion during the testing duration is below the first threshold, even if the average amount of motion during the testing duration is greater than the second threshold.
