Abstract
The present invention is directed to a wearable fitness and/or heart rate monitoring device which includes motion detecting sensor(s), a galvanic skin response (GSR) sensor, a user input interface, or any combination thereof. The device accounts for signal noise, produced when an individual passes thru varying exercise states, by filtering out the motion of the individual using a 3-axis accelerometer. The invention also provides for systems and methods of operating the monitor which extracts and/or stores true or correct heart rate values from the heartbeat waveform signal observed from a PPG.
