Abstract: The present invention provides a step counting method and device. The method comprises the following steps performed repeatedly: a) obtaining three monoaxial acceleration signals with a predetermined length from triaxial output of a triaxial acceleration sensor worn on a walkrunner; b) performing high-pass filtering on each obtained monoaxial acceleration signal; c) performing pitch detection on each high-pass filtered monoaxial acceleration signal; d) using the pitch obtained in each pitch detection as a cut-off frequency to set a low-pass or band-pass filter, and performing low-pass or band-pass filtering on corresponding high-pass filtered monoaxial acceleration signal by using it; e) obtaining acceleration signal extreme value points from each low-pass or band-pass filtered monoaxial acceleration signal and removing interfering extreme value points therein; f) counting the number of the acceleration signal extreme value points after the interfering extreme value points have been removed; g) determining the accumulative walkrun step number of the walkrunner. The method can count steps accurately.

Abstract: A wearing state detection method for a wearable device and a device. The detection method comprises: providing in the wearable device a sensor in an area capable of contacting the skin of a user, wherein the sensor outputs different measurement values when the user wears or takes off the wearable device; acquiring a base value indicating whether the wearable device is being worn; after wearing detection has been started up, collecting measurement values from the sensor at a preset sampling frequency; judging whether the wearable device is currently in a wearing state according to the measurement values and the base value; and controlling the wearable device to turn off a corresponding function that is running when the wearable device is in a non-wearing state. The method and the device can reduce the power consumption and simplify user operation.

Abstract: A method and device for identifying a human movement state that includes: determining according to acceleration signals that are collected by a three-axis acceleration sensor that a human is in a walking state, calculating a walking step number of the human, and calculating a walking step frequency according to the number; calculating a corresponding physical sign frequency during the walking process according to a physical sign signal that is collected; and comparing the walking step frequency and the physical sign frequency that are obtained by calculating respectively with a step frequency threshold and a physical sign frequency threshold, and if the walking step frequency is greater than the step frequency threshold, and the physical sign frequency is greater than the physical sign frequency threshold, determining that the human movement state is a running state, and recording the calculated walking step number to be a running step number.
