Abstract

A method and system for providing a sound source suitable for an exercise state of a user by recognizing the exercise state of the user by measuring heart rate and exercise speed of the user. The method includes: determining a standard heart rate; measuring a heart rate of a user; measuring an exercise speed of the user; comparing the measured heart rate and the standard heart rate; when a difference between the both heart rates is more than a predetermined value, generating compensated exercise speed information based on the difference and the measured exercise speed; and replaying a sound source according to the compensated exercise speed information. According to the exercise state management method, heart rate suitable for the type, intensity, or time of exercise selected by the user and a sound source suitable for exercise speed are provided, thereby improving satisfaction and effectiveness of the exercise.

Claims

1. A method of managing an exercise state in an exercise state management apparatus, comprising:

determining a standard heart rate;

measuring a heart rate of a user;

measuring an exercise speed of the user;

comparing the measured heart rate and the standard heart rate to determine a difference between the rates;

generating compensated exercise speed information based on the difference and the measured exercise speed, when the difference is more than a predetermined value; and

replaying a sound source according to the compensated exercise speed information.

2. The method of claim 1, wherein, in the generating compensated exercise speed information,

when the measured heart rate is faster than the standard heart rate, first compensated exercise speed information for decreasing the heart rate of the user is generated;

and

when the heart rate is slower than the standard heart rate, second compensated exercise speed information for increasing the heart rate of the user is generated.

3. The method of claim 1, wherein the determining a standard heart rate comprises:

measuring a stable heart rate of the user;

receiving a maximum heart rate from the user;

determining a target heart rate based on the received maximum heart rate;

receiving exercise information from the user; and

determining the standard heart rate by using the stable heart rate, the target heart rate, and the exercise information.

4. The method of claim 3, wherein the exercise information includes at least one of exercise intensity, exercise type, and exercise time information.

5. The method of claim 3, wherein, in the determining the standard heart rate by using the stable heart rate, the target heart rate, and the exercise information, a warm-up standard heart rate or a cool-down standard heart rate is determined based on the stable heart rate and the target heart rate according to the exercise information, and

wherein the target heart rate is determined to be a sustained exercise standard heart rate.

6. The method of claim 1, further comprising:

determining whether the measured heart rate is normal; and

generating a warning sound when the measured heart rate is not normal.

7. The method of claim 1, further comprising providing feedback to the user on the measured heart rate and the measured exercise speed.

8. The method of claim 1, wherein, in the measuring a heart rate of the user, the heart rate of the user is measured via a photoplethysmography (PPG) sensor, and

wherein, in the measuring an exercise speed of the user, the exercise speed of the user is measured via an acceleration sensor.

9. The method of claim 1, further comprising storing and maintaining a sound source corresponding to each exercise speed in a memory,

wherein, in the replaying the sound source corresponding to the compensated exercise speed, the sound source corresponding to the compensated exercise speed information is extracted from the memory and replayed.

10. The method of claim 1, further comprising:

computing an exercise cool-down coefficient of the user by using a first heart rate of the user, which is measured when the user completes an exercise, and a second heart rate of the user, which is measured when a predetermined time passes after the exercise is completed;

displaying the computed exercise cool-down coefficient of the user; and

storing the computed exercise cool-down coefficient of the user.

11. The method of claim 10, further comprising displaying an exercise cool-down coefficient tendency computed by using the computed exercise cool-down coefficient and a previous exercise cool-down coefficient of the user, which is stored when the user performed an exercise previously.

12. The method of claim 11, further comprising:

receiving exercise evaluation information from the user; and

displaying exercise tendency information and the received exercise evaluation information of the user.

13. A computer-readable recording medium encoded with processing instructions for causing a processor to execute a method of managing an exercise state in an exercise state management apparatus, the method comprising:

determining a standard heart rate;

measuring a heart rate of a user;

measuring an exercise speed of the user;

comparing the measured heart rate and the standard heart rate to determine a difference between the rates;

generating compensated exercise speed information based on the difference and the measured exercise speed, when the difference is more than a predetermined value; and

replaying a sound source according to the compensated exercise speed information.

14. An exercise state management apparatus comprising:

a measurement unit measuring a heart rate of a user and an exercise speed of the user;

a sound source replay unit replaying a sound source; and

a control unit determining a standard heart rate and, generating compensated exercise speed information based on a difference of the measured heart rate and a measured exercise speed, when the difference between the measured heart rate and a standard heart rate is more than a predetermined standard value, and controlling the sound source replay unit to replay a sound source corresponding to the compensated exercise speed information.

15. The apparatus of claim 14, wherein the measurement unit comprises a photoplethysmography (PPG) sensor measuring the heart rate of the user and an acceleration sensor measuring the exercise speed of the user.

16. The apparatus of claim 14, further comprising a communication unit receiving a sound source transmitted from a sound source providing apparatus connected via a network,

wherein the control unit controls the sound source replay unit to adjust replay speed of the received sound source according to the compensated exercise speed information.

17. The apparatus of claim 14, further comprising an alarm unit providing one of visual alarm, audible alarm, and electric alarm,

wherein the control unit determines whether the heart rate of the user is normal by comparing with the measured heart rate and, when the heart rate of the user has an abnormality, controls the alarm unit to provide an alarm corresponding to the abnormality of the heart rate.

18. The apparatus of claim 14, further comprising a display unit displaying exercise condition information and an exercise cool-down coefficient data of the user,

wherein the control unit computes the exercise cool-down coefficient based on a first heart rate measured when the user completes an exercise and a second heart rate measured when a certain time passes after the exercise is completed and controls the display unit to display the computed exercise cool-down coefficient data and the exercise state information.

19. The apparatus of claim 14, further comprising an input unit receiving exercise information from the user,

wherein the control unit determines the standard heart rate by using the exercise information received from the input unit, a computed maximum heart rate, and a target heart rate.

20. The apparatus of claim 14, wherein the controller:
