Abstract

Both the beat and genre of music are used to select or generate a dance robot object for display of a robot icon on a computer monitor or for establishing the movements of a three-dimensional robot. The detected genre can define the type of dance performed by the robot. Also, the detected genre can be used to sort music. The genre can be detected using a neural network or by correlating the compressibility of the music to a genre.

Claims

1. A computer-implemented method for detecting and using music genre, comprising:

receiving at a three dimensional movable dance robot an analog version of an audio signal representing music;

digitizing the signal;

determining a genre of the music for output thereof based on determining a compressibility of the music, the compressibility being correlatable to a music genre;

based on the genre, establishing movements of the dance robot.

2. The method of claim 1, wherein if the music is relatively incompressible, the detected genre is indicated as being rock music, and if the music is relatively compressible, the detected genre is indicated as being classical music.

3. The method of claim 2, wherein the compressibility is determined using a lossless compression algorithm.

4. The method of claim 1, comprising selecting one of plural dance robot objects based on the genre.

5. The method of claim 1, comprising storing the music based on the genre.

6. A computer system, comprising:

at least one processor in a three dimensional dance robot aurally receiving music which is digitized and sent to the processor;

the processor executing logic for determining a genre of the music by determining how compressible the music is and correlating how compressible the music is to a genre, and based thereon establishing movement of the robot.

7. The system of claim 6, wherein the logic further includes storing the music in a genre-sorted data storage.

8. The system of claim 6, wherein if the music is relatively incompressible, the detected genre is indicated as being rock music, and if the music is relatively compressible, the detected genre is indicated as being classical music.

9. A computer system, comprising:

a three dimensional dance robot;

at least one processor in the dance robot aurally receiving aural music, the robot digitizing the aurally received music and providing the digitized music to the processor;

means available to the processor for determining at least a beat of music and how much the music can be compressed;

means available to the processor for determining a genre of the music based on the amount the music can be compressed; and

means for establishing a dance motion of the robot based at least in part on the beat and genre.

10. The system of claim 9, comprising means available to the processor for storing the music in a genre-sorted data storage.
