1. A wearable device comprising:

  • a position detection module;

    a sensor that includes at least one of an acceleration sensor, a geomagnetic sensor, and an atmospheric pressure sensor; and

    a processor that is electrically connected to the position detection module and the sensor, and is programmed to;

    determine a behavior state of a user wearing the wearable device based on signals from both the position detection module and the sensor;

    in response to detecting a first predefined condition of the behavior state of the user, deactivate the position detection module while continuing to activate the sensor; and

    while the position detection module is deactivated, in response to detecting a second predefined condition of a signal from the sensor, reactivate the position detection module.
