1. A wearable device comprising:
- a touch screen configured to display information;
an acceleration sensor configured to generate an acceleration signal;
an optical sensor comprising a light source and configured to generate a touch interrupt signal; and
a control unit configured to;
determine a wearing state of the wearable device based on the acceleration signal or the touch interrupt signal, the wearing state comprising a not-wearing state, a wrist-wearing state, or a hand-gripping state; and
execute a function corresponding to the determined wearing state;
display a first screen representing that the touch screen is turned off if the wearable device is in the not-wearing state,display a second screen representing a watch screen if the wearable device is in the wrist wearing state, anddisplay a third screen including notification information if the wearable device is in the hand gripping state,wherein each of the first screen, the second screen and the third screen is a lock screen or a lock release screen,the lock screen is a screen for limiting an access of an application in the wearable device, andthe lock release screen is a screen for allowing the access of the application in the wearable device.
