<P>PROBLEM TO BE SOLVED: To provide a personal digital assistant with which music performance is easily attained. <P>SOLUTION: Music data of one octave is allocated to each button of a portable telephone. When the portable telephone is set at a mode to reproduce a musical instrument, the portable telephone reads and saves the data of an inclination sensor and geomagnetic sensor in a steady state (step S402). When the user presses a button on the portable telephone (step S403; Yes), the portable telephone re-reads the data of the inclination sensor and the geomagnetic sensor, and calculates the difference from the data in the steady state. The portable telephone determines the method for changing the music data, based on the calculated difference (step S404) and reproduces the music data from a music reproduction loudspeaker, after changing the music data by the determined changing method (step S405). <P>COPYRIGHT: (C)2007,JPO&INPIT |
