An operating apparatus for a hand-held electronic apparatus includes a motion sensor, an analog to digital converting module and a processing unit. The motion sensor is utilized for sensing a motion track of the hand-held electronic apparatus to generate an analog sensing signal. The analog to digital converting module is coupled to the motion sensor, and is utilized for converting the analog sensing signal into a digital sensing signal. The processing unit is coupled to the analog to digital converting module, and is utilized for executing a multimedia motion control software to determine whether the motion track of the hand-held electronic apparatus corresponds to a predetermined track according to the digital sensing signal. Furthermore, the processing unit executes at least one predetermined function corresponding to the predetermined track from a plurality of predetermined functions when determining that the motion track corresponds to the predetermined track.
