1. A wearable fitness monitoring device comprising:
- a motion sensor configured to provide output corresponding to motion by a user wearing the fitness monitoring device;
a heartbeat waveform sensor; and
control logic comprising instructions for;
(a) collecting concurrent output data from the heartbeat waveform sensor and output data from the motion detecting sensor, wherein the output data from the heartbeat waveform sensor provides information about the user'"'"'s heart rate and wherein the output data from the motion detecting sensor provides information about the user'"'"'s periodic physical movements other than heartbeats;
(b) analyzing the output data from the motion detecting sensor to determine a periodic component of the output data from the motion detecting sensor;
(c) analyzing the output data from the motion detecting sensors to determine a non-sedentary activity type of the user selected from among two or more non-sedentary activity types;
(d) based on the user'"'"'s determined non-sedentary activity type determined in (c), determining that motion compensation should be applied;
(e) using the periodic component of the output data from the motion detecting sensor to remove a corresponding periodic component from the output data from the heartbeat waveform sensor;
(f) determining the user'"'"'s heart rate; and
(g) presenting the user'"'"'s heart rate.

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 collecting concurrent output data from the heartbeat waveform sensor and output data from the motion detecting sensor, detects a periodic component of the output data from the motion detecting sensor, and uses the periodic component of the output data from the motion detecting sensor to remove a corresponding periodic component from the output data from the heartbeat waveform sensor. From this result, the device may determine and present the user'"'"'s heart rate.
