<P>PROBLEM TO BE SOLVED: To reproduce a sound such as music so that a user can always have a sense of unity with one's own movements without being made to feel unnaturalness such as a sense of incompatibility. <P>SOLUTION: The operation tempo of the user is detected via a movement information sensor 24 and a movement information analysis circuit 23, and a control section 10 retrieves music data having a tempo corresponding to the operation tempo from a recording medium in a music information storage device section 21 and reproduces the music data. When the music data having the tempo corresponding to the operation tempo of the user cannot be retrieved, the control section 10 controls a music reproduction data generation device section 22 to retrieve one or both of music data having a tempo whose difference from an integral multiple of the operation tempo is within a specified range and music data having a tempo whose difference from the reciprocal of an integral multiple of the operation tempo is within a specified range, and reproduces detected audio data. <P>COPYRIGHT: (C)2007,JPO&INPIT |
