Abstract: |
A biometric monitoring device is used to determine a user's heart rate by using a heartbeat waveform sensor and a motion detecting sensor. In some embodiments, the device collects output data from the heartbeat waveform sensor and output data from the motion detecting sensor, determines an expected heart rate range from the output data from the motion detecting sensor, and determines the user's heart rate within the expected heart rate range using the output data from the heartbeat waveform sensor. |
