Motion analyzing apparatus and method for a portable device

A motion analyzing apparatus for a portable device with an output unit, the motion analyzing apparatus comprising:

• a music database storing at least one music data;
• a motion sensor unit sensing displacement variations of the portable device and outputting corresponding motion signals;
• and
• a microprocessor unit, for receiving the motion signals, comparing the motion signals with the music data, and outputting a control signal to the output unit according to the comparison result.

A motion analyzing method for a portable device with a database, the motion analyzing method comprising following steps:

• executing a motion program to sense displacement variations of the portable device to obtain motion signals;
• comparing continually the motion signals and a motion pattern stored in the database that corresponds to the motion program, and storing the comparison result in a storage unit;
• and
• determining whether the sensing of the motion program is finished or not, if the answer is yes, analyzing the comparison result as a whole and outputting the analysis result.
