Abstract:
In some implementations, a mobile device can receive a motion signal from a motion sensor on the mobile device. The mobile device can determine a step count based on the motion signal. The mobile device can transform the motion signal from a time domain signal into a frequency domain signal. The mobile device can determine a dominant peak and harmonic peaks of the motion signal within a pedestrian frequency band. The mobile device can determine that the dominant peak corresponds to an arm swing of a user and adjust the step count to compensate for the arm swing.
