Dependent claims

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;
