Abstract: The present invention relates generally to a method for providing motion information for motion recognition mode to user in a portable terminal. In the method, when using the motion recognition mode, the first notification is provided. It is determined if the sensed gesture of the user can be recognized. If the gesture cannot be recognized, the second notification is provided. If the user's gesture can be recognized, the motion recognition of the gesture is performed and compared with pre-registered gestures in the portable terminal. If the gesture is not a registered gesture, the third notification is provided. If the recognized gesture is registered, a function corresponding to the recognized gesture is selected and performed. The above method enables a user to effectively utilize a portable terminal equipped with motion recognition capabilities.
