Abstract:
1. A motion data generation device comprising: a storage unit that stores a plurality of motion pattern datasets, each motion pattern dataset corresponding to a predetermined motion pattern; a beat detection unit that analyses music data and detects a beat of music based on the music data; an interval dividing unit that divides the music data into a plurality of beat intervals based on the beat detected by the beat detection unit; a data allocation unit that allocates to each beat interval of the music data a motion pattern dataset from among the plurality of motion pattern datasets stored in the storage unit and extends or contracts a motion pattern corresponding to said allocated motion pattern dataset so that a pattern start and a pattern end of said motion pattern match with a beat beginning and a beat end of said beat interval of the music data; and a data generation unit that generates motion data in accordance with the motion pattern dataset allocated to each respective beat interval of the music data by the data allocation unit.
