This paper designs a method based on the combination of zero crossing detection and peak detection algorithm. The main idea of this algorithm is to detect the uplink zero point, the downlink zero point and the peak of the acceleration waveform, and count user’s step number by the dynamic threshold of the peak and time interval. In the experiment, we allow users to hold the phone in hand or keep it in the pocket. The validity of the algorithm is verified by experiments.
