    Abstract: PROBLEM TO BE SOLVED: To provide a pedometer device and a step detection method using the algorithm of the self-adaptive computation of an acceleration threshold.
    SOLUTION: The pedometer device 1 detects the walking steps of a user on foot, and an acceleration sensor 2 detects vertical acceleration generated during walking steps for counting. A processor 3 is connected to the acceleration sensor 2, and processes an acceleration signal CalAcc relating to acceleration A in order to detect the occurrence of the walking steps, and especially compares the acceleration signal CalAcc with a first reference threshold S+. The processor 3 automatically adapts a first reference threshold S+ as the function of the acceleration signal CalAcc. In particular, the processing unit 3 modifies the first reference threshold S+ as the function of an envelope Env+ of the amplitude of the acceleration signal.
