Original Abstract Submitted

a device for determining a heart rate of a user has a ppg sensor and an accelerometer to compensate for acceleration artifacts within the ppg signal. the device transforms time domain ppg and accelerometer signals into the frequency domain using a fourier transformation and utilizes the fourier coefficient magnitudes as indicative of the probability of candidate heart rate values. candidate heart rate values are determined at sampling times over a time interval and a most probable heart rate path during the time interval is determined using a reward/penalty algorithm.
