Electronic device controlled by a motion and controlling method thereof using different motions to activate voice versus motion recognition

摘要

An electronic device is provided. The electronic device includes a motion recognition unit which recognizes motion of an object and a control unit which, if a push motion in which the object located in front of the electronic device is moved in a direction of the electronic device is sensed by the motion recognition unit, activates a motion recognition mode, tracks the motion of the object, and performs a control operation of the electronic device corresponding to a subsequent motion of the object. The control unit may inactivate the motion recognition mode if an end motion in which the motion of the object is in a direction to contact a body part of a user or an additional object is recognized by the motion recognition unit while the motion recognition mode is activated. Furthermore a voice recognition mode may be activated by recognition of a motion different from the push motion.
