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.

Abstract
A running watch which is a wearable device includes a position detection unit (a GPS module), a sensor unit including at least one of an acceleration sensor, a geomagnetic sensor, and an atmospheric pressure sensor, and a processing unit electrically connected to the position detection unit and the sensor unit. The processing unit determines a behavior state of a user based on signals from the position detection unit and the sensor unit and controls at least two of the position detection unit, the acceleration sensor, the geomagnetic sensor, and the atmospheric pressure sensor based on the behavior state.

15. A method of controlling a wearable device, comprising:
causing a processor of the wearable device to; determine a behavior state of a user wearing the wearable device based on signals from both a position detection sensor and another sensor, the other sensor including at least one of an acceleration sensor, a geomagnetic sensor, and an atmospheric pressure sensor; in response to detecting a first predefined condition of the behavior state of the user, deactivate the position detection sensor while continuing to activate the other sensor; and while the position detection sensor is deactivated, in response to detecting a second predefined condition of a signal from the other sensor, reactivate the position detection sensor. - View Dependent Claims (16, 17, 18)

19. A wearable device comprising:
-
a first sensor; a second sensor; and a processor programmed to; determine a movement of a user wearing the wearable device based on signals from both the first sensor and the second sensor; detect a first predetermined condition of the movement of the user; in response to detecting the first predetermined condition of the movement of the user, deactivate the first sensor such that the movement of the user is determined based on a current signal from only the second sensor; and while the first sensor is deactivated, in response to detecting a second predetermined condition of the current signal from the second sensor, reactivate the first sensor. - View Dependent Claims (20, 21)
