Wearing state detection method for wearable device, and wearable device

A wearable device, wherein the wearable device comprises:

• a sensor and a control circuit;
• the sensor is provided in the wearable device in an area capable of contacting the skin of a human body, wherein the sensor outputs different measurement values when the user wears or takes off the wearable device;
• the control circuit comprises:
• a collecting module, a detecting and processing module and an outputting control module;
• the collecting module connects to the sensor, and after wearing detection has been started up, the collecting module collects measurement values from the sensor at a preset sampling frequency;
• the detecting and processing module connects to the collecting module, and the detecting and processing module receives the measurement values that are collected by the collecting module, acquires a base value indicating whether the wearable device is being worn, and judges whether the wearable device is currently in a wearing state according to the measurement values and the base value;
• and
• the detecting and processing module connects to the outputting control module, the detecting and processing module notifies the outputting control module when detecting that the wearable device is in the non-wearing state, and the outputting control module controls the wearable device to turn off a corresponding function that is running;
• wherein the detecting and processing module acquires a smooth value that corresponds to each of the measurement values that are collected by the collecting module, and regarding a current measurement value, judges whether the current measurement value is in a stable state, when the current measurement value is stable, judges whether all of a preset number of measurement values before and after the current measurement value are in the stable state, or, judges whether all of a preset number of measurement values before the current measurement value are in the stable state;
• and if yes, judges whether the wearable device is currently in the wearing state according to a smoothed value that corresponds to the current measurement value and the base value.
