1. A wearable device comprising:
- a main body;
a display located at a front side of the main body and configured to display information;
a heartbeat sensor located below the display and located at a rear side of the main body, wherein the heartbeat sensor comprises a light emitting unit and a light receiving unit, and wherein the heartbeat sensor is configured to detect a heartbeat using the light emitting unit and the light receiving unit; and
a controller operably coupled with the display and the heartbeat sensor, wherein the controller is configured to;
display, on the display, a lock screen representing a lock state;
identify a wearing state of the wearable device and a non-wearing state of the wearable device using the light emitting unit and the light receiving unit;
change the lock state of the wearable device to a lock released state of the wearable device in response to receiving of a lock release command after identifying that the wearable device is in the wearing state;
display a lock released screen if the display is turned on after the display is turned off while the wearable device is in the wearing state;
change the lock state to the lock released state in response to receiving of the lock release command after identifying that the wearable device is in the non-wearing state; and
