Abstract
A method for detecting a heart rate is disclosed and includes: providing a photodetector module, a motion detector and a Fast Fourier Transform (FFT) module; acquiring a first heart rate using the photodetector module and the FFT module; sampling at different time intervals and generating a frame using the motion detector and the FFT module, wherein the frame has a first plurality of peaks and a first plurality of indexes corresponding to the first plurality of peaks, and a plurality of sport intervals are defined by the first plurality of indexes; and acquiring a present heart rate by applying an interval tracking algorithm to the first heart rate and the plurality of sport intervals generated from the sampling at different time intervals.
