Abstract

A music reproduction device for recommending music suitable for a taste of a user is provided. When the music reproduction device reproduces music, a motion of the user is measured. A range of a tempo in which a tempo of music is matched with a tempo of the motion of the user is determined as a range of a preferred tempo of the user. Pieces of music to be recommended for the user are selected based on the determined range of the tempo. Thus, it is possible to accurately recommend pieces of music suitable for the taste of the user without an additional input for generating a recommendation list by the user.

Claims

1. A method of determining a preference of music of a user by using a music reproduction device, the method comprising:

sensing motions of the user while music is reproduced by the music reproduction device;

comparing a tempo of the sensed motions with a tempo of the music; and

determining a range of a preferred tempo of the user based on a result of the comparing.

2. The method of claim 1, wherein the sensing the motions of the user comprises sensing motions of a head of the user using a three-dimensional motion sensor.

3. The method of claim 2, wherein the comparing of the tempo of the sensed motions with the tempo of the music comprises comparing a tempo that is most similar to the tempo of the music among tempos of the motions of the head of the user in x-axis, y-axis, and z-axis motion directions with the tempo of the music.

4. The method of claim 1, wherein the determining the range of the preferred tempo of the user comprises determining the range of the preferred tempo of the user based on how frequently the tempo of music matches with the tempo of the corresponding motions of the user.

5. The method of claim 1, wherein the tempo of the music is a base beat.

6. The method of claim 1, further comprising generating a list of music to be recommended for the user based on the determined range of the tempo.

7. The method of claim 1, further comprising modifying a previously determined range of the tempo based the determined range of the tempo.

8. A computer-readable recording medium having embodied thereon a computer program for executing the method of claim 1.

9. A device for determining a preference of music of a user by using a music reproduction device, the device comprising:

a sensing unit which senses motions of the user while music is being reproduced by the music reproduction device;

a comparison unit which compares a tempo of the sensed motions with a tempo of the music; and

a determination unit which determines a range of a preferred tempo of the user based on a result of the comparison by the comparison unit.

10. The device of claim 9, wherein the sensing unit senses motions of a head of the user using a three-dimensional motion sensor.

11. The device of claim 10, wherein the comparison unit compares a tempo that is most similar to the tempo of the music among tempo of motions of a head of the user in x-axis, y-axis, and z-axis motion directions with the tempo of the music.

12. The device of claim 10, wherein the determination unit determines the range of the preferred tempo of the user based on a frequency in which the tempo of the music matches with the tempo of the motion of the user.

13. The device of claim 10, wherein the tempo of the music is a base beat.

14. The device of claim 10, further comprising a recommendation unit which generates a list of music to be recommended for the user based on the determined range of the tempo.

15. The device of claim 10, wherein the determination unit modifies a previously determined range of the tempo based the determined range of the tempo.
