Electronic device and method for activating applications therefor

A method in an electronic device comprising:

• storing in a memory one or more applications associated with one or more preset conditions;
• selecting, by a processor, at least one sensor among one or more sensors for detecting a movement of the electronic device, and selecting a sampling frequency for the selected at least one sensor based on usage state information of the electronic device and a user activity state;
• detecting the movement of the electronic device using the selected at least one sensor operating at the selected sampling frequency;
• and
• if the movement satisfies a preset condition of the one or more preset conditions, executing a specific application of the one or more applications associated with the preset condition.

An electronic device comprising:

• a housing;
• a fastener mounted on a portion of the housing and removably attachable to a user;
• a display exposed through a portion of the housing;
• at least one sensor disposed within the housing and configured to detect movement of the electronic device;
• a processor disposed within the housing and electrically coupled with the display and the at least one sensor;
• and
• a memory electrically coupled with the processor, the memory storing instructions executable by the processor to:
• receive first data from the at least one sensor when the display is deactivated;
• in response to detecting that the first data indicates a first pattern of movement of the electronic device, activate the display;
• receive second data from the sensor after the display is activated;
• and
• in response to detecting that the second data indicates that a repetition of the first pattern exceeds a reference value, deactivate the display.
