Description

Method for determining exercise section

The present invention relates to an exercise section determination method, and more particularly, to an exercise section determination method capable of detecting both a dynamic exercise section and a static exercise section.

BACKGROUND Electronic devices are gradually miniaturizing and slimming while performing the same or various functions, and are being developed in a direction that is easy to carry. Such small electronic devices are generally housed in a user's pocket or the like, but are worn on the wrist or worn on the head portion or arm of a human body.

When the user wears such a wearable device on the body to exercise, it is very important to distinguish between a section in which the exercise is actually performed and a section in which the exercise is not performed. In the past, it was common to use an acceleration sensor in a device that can be worn on the body in order to detect an exercise section. For example, when determining an exercise section using a wearable device worn on a wrist, the user may determine whether the user is exercising by detecting a movement of the wrist using an acceleration sensor in the wearable device.

However, if it is determined whether the user is exercising using only the acceleration sensor in this way, the user can easily detect the movement of the part wearing the device, but in the case of the static exercise, the exercise is not performed. There is a problem to decide. For example, in a case where a wearable device is worn on a wrist and a cycle is measured using only an acceleration sensor, there is a problem that it is determined that the user does not exercise even when exercising.

The problem to be solved by the present invention is to provide a method for determining an exercise section that can detect both a dynamic exercise section and a static exercise section.

When the magnitude of the acceleration information detected by the second sensor is greater than or equal to a threshold value in a previous section of the end of the exercise, the time point at which the acceleration starts to increase using the acceleration information calculated from the signal detected by the second sensor Determining an exercise start time and detected by the second sensor in a previous section of the exercise end time If the magnitude of the acceleration information is less than the threshold value, using the heart rate information calculated from the signal sensed by the first sensor may include the step of determining the starting point of the increase in the heart rate as the exercise start time.

The determining of the end point of the exercise may include calculating a change in heart rate using heart rate information calculated from the signal sensed by the first sensor, and when the calculated heart rate change is within a first critical section. The method may include determining and correcting whether the values are continuous values, and determining a time point at which the heart rate begins to decrease by using the corrected heart rate change amount as an end point of the exercise.

The correcting may include: when the time difference between the first time point at which the change in heart rate decrease is within the first critical section and the second time point at which the change in heart rate reduction is within the first critical section is less than or equal to a first reference time, The method may include correcting the change in the heart rate decrease within the first critical section from one time point to the second time point.

The determining of the starting point of the acceleration as an exercise starting point may include: removing directional information from the signal detected by the second sensor and calculating acceleration information including only magnitude information, and calculating the calculated acceleration information. The method may include determining and correcting whether the value is a continuous value, and determining a time point at which the acceleration starts to increase using the corrected acceleration information as the start point of the exercise.

The determining of the start point of the heart rate as an exercise start time may include calculating a change in heart rate using heart rate information calculated from the signal detected by the first sensor, and the calculated heart rate increase amount is The method may include determining whether the values are continuous values within two critical sections, and determining a time point at which the heart rate begins to increase using the corrected heart rate change.

The correcting may include: when the time difference between the first time point in which the change in heart rate increase is within the second critical section and the second time point in which the change in heart rate increase is within the second critical section is less than or equal to a second reference time, And continuously correcting the change in heart rate to within the second critical section from one time point to the second time point.

Hereinafter, a method of determining an exercise section according to an embodiment of the inventive concept will be described with reference to FIGS. 1 to 7. Each step described below may be performed in a server or a computer, or may be performed in a device including the first sensor and the second sensor.

According to an embodiment of the present disclosure, a method for determining an exercise section may include using information detected by the first sensor and the second sensor in a state in which a device including a first sensor and a second sensor is coupled to a body. The exercise section can be determined by determining the start point and the end point of the exercise. The device that can be coupled to the body may be various devices such as a wearable device, a smartphone, the first sensor may be a sensor for obtaining heart rate information, and the second sensor may be a sensor for obtaining acceleration information. Can be. For example, the first sensor may be an optical volume pulse wave sensor capable of measuring plethysmography (PPG), and the second sensor may be a three-axis acceleration sensor capable of measuring an acceleration signal. However, if the first sensor of the present invention is a sensor capable of obtaining heart rate information, it may be another sensor in addition to the optical volume pulse wave sensor, and if the second sensor is a sensor capable of obtaining acceleration information, it may be another sensor in addition to the three-axis acceleration sensor. It may be.

In order to determine the exercise section, first, the time point at which the heart rate begins to decrease may be determined as the exercise end time point using the heart rate information calculated from the signal detected by the first sensor (S110). Preprocessing the signal sensed by the first sensor may be performed first to find a time point at which the heart rate begins to decrease. For example, when the signal detected by the first sensor is an optical volumetric pulse wave signal, a peak value of the detected optical volumetric pulse wave signal may be detected, and the heart rate may be calculated by dividing by a median value of heart rate variability. In calculating the heart rate using the signal sensed by the first sensor, Equation 1 below may be used.

May mean unit time. 2 (a) shows the unit time of the signal detected by the first sensor (

= 60 sec) divided by the median of heart rate variability (HRV) detected for 10 seconds. However, in calculating the heart rate in the present invention, Equation 1 is not necessarily used, and heart rate may be calculated from the signal detected by the first sensor using various other methods.

Calculating a change in heart rate using heart rate information calculated from a signal sensed by the first sensor, to determine a time point at which the heart rate begins to decrease, wherein the calculated change in heart rate is within a first critical section; Determining whether the values are continuous values and correcting the cases may be performed, and determining the time point at which the heart rate begins to decrease using the corrected heart rate change amount as the end point of the exercise.

The first threshold section may be a section between the first threshold change amount and the second threshold change amount. When the change in heart rate is smaller than the first threshold change amount or when the change in heart rate is greater than the second threshold change amount, it is highly likely to be noise or non-movement. It may be determined to be a valid value only if it is within the first critical section.

The heart rate reduction amount may be defined as a derivative of the heart rate with respect to time, and it may be determined whether the heart rate change amount is within the first critical section by using Equation 2 below.

는 상기 제 1 임계변화량,

는 상기 제 2 임계변화량일 수 있다.Where HR is heart rate, t is time,

Is the first threshold change amount,

May be the second threshold change amount.

When the time difference between the first time point in which the change in heart rate decrease is within the first critical section and the second time point in which the heart rate change amount is within the first critical section is less than or equal to a first reference time, the second time point at the first time point; The change in heart rate reduction may be corrected to be within the first critical section continuously up to a time point. In other words, it can be determined that the actual exercise is finished and the heart rate is reduced only when the heart rate is decreased in the continuous section, so that the section in which the heart rate is continuously reduced can be found.

For example, the state in which the heart rate calculated as shown in FIG. 2 (a) is differentiated with respect to time is shown in FIG. 2 (b), and each time point as shown in FIG. 2 (c) using Equation 2 is shown. The heart rate reduction may be changed to a value having a value of 0 or 1 depending on whether the amount of change in heart rate is within the threshold period. The result of determining whether the heart rate decreases in the continuous section of FIG. 2C is shown in FIG. 2D. That is, referring to (d) of FIG. 2, since the section in which the heart rate decreases becomes the P1 section and the P2 section, the start point of the P1 section and the start point of the P2 section are determined as the end point of the exercise. A method of skipping from (c) to (d) of FIG. 2 will be described in more detail with reference to FIG. 3.

In determining and correcting whether the heart rate reduction amount is a continuous value, a time difference between a first time point in which the heart rate change amount is within the first critical section and a second time point in which the heart rate change amount is within the first critical section is different. If it is less than or equal to the first reference time, the change in heart rate decreases continuously from the first time point to the second time point, and is corrected to be within the first critical section. Otherwise, the heart rate change amount is changed after the first time point. It may be determined that it is not within the first critical section.

In the case of FIG. 3, since the first reference time is exceeded between the time point t1 and the time point t2, it is determined that the section in which the heart rate decreases is not continuous, and the time point between the time point t3 and the time point t4 also exceeds the first reference time. The section in which the heart rate was decreased was determined to be a continuous section until t3. In addition, in determining the time between t5 and t8, the time between t6 and t7 is less than the first reference time, so it is determined that the t5 to t7 point is a continuous section. As a result, the t5 to t8 point is continuous. Judging by

As such, when the continuous section is determined, a start point of the continuous section may be determined as an end point of the exercise. As described above, when the timing at which the heart rate begins to decrease in step S110 is determined as the end of the exercise, the acceleration information detected by the second sensor may be compared with the threshold in the section before the end of the exercise (S120). For example, as shown in FIG. 5, the acceleration information is compared with the threshold value in the section Px before the exercise end point t2, and the acceleration information and the threshold value in the section Py before the exercise end point t5. Can be compared.

When the magnitude of the acceleration information is greater than or equal to the threshold value, it corresponds to a case where the user performs a dynamic exercise with a large movement. In this case, a time point at which the acceleration information starts to increase may be determined as a start time of exercise (S130). . That is, when the user performs a dynamic exercise, there is a risk that the heart rate information may not be accurate. In determining the start time of the exercise, the user may ignore the heart rate information and determine the start time of the exercise using only the acceleration information. Can be.

In addition, when the magnitude of the acceleration information is less than the threshold value, the user may perform a static exercise with little movement or may not be exercising. In this case, a time point at which the heart rate information starts to increase The exercise start time may be determined (S140). That is, when the user performs a static exercise, it is difficult to determine the starting point of the exercise using the acceleration information. Therefore, when determining the starting point of the exercise, the starting point of the exercise is ignored using only the heart rate information in ignoring the acceleration information. It may be determined (S140).

In FIG. 4, since the magnitude of the acceleration information is less than the threshold value in the Px section and the magnitude of the acceleration information is greater than or equal to the threshold value in the Py section, the acceleration starts to increase only in the Py section as shown in FIG. 5. Finding a point of view may determine this as the start of exercise, and as shown in FIG. 6, a point of time in which the heart rate increases only in the Px section may be found and determined as the start of exercise.

A method of finding a time point at which the acceleration starts to increase using the acceleration information calculated from the acceleration signal detected by the second sensor will be described with reference to FIG. 5. The method for finding a time point at which the acceleration starts to increase includes: calculating acceleration information including only size information by removing directional information from a signal sensed by the second sensor, and successive values using the calculated acceleration information. And determining and recognizing and recognizing the image, and determining a time point at which the acceleration starts to increase using the corrected acceleration information.

First, the acceleration signal detected by the second sensor can remove the directional information and calculate only the magnitude. As a result, a graph is calculated as shown in FIG. For example, in the case of the acceleration signal sensed using the 3-axis acceleration, the momentum m calculated only by magnitude may be calculated by removing the directional information using Equation 3 below.

는 y축 가속도 신호,

는 z축 가속도 신호를 의미할 수 있다.here

Is the x-axis acceleration signal,

Is the y-axis acceleration signal,

May mean a z-axis acceleration signal.

By using the calculated momentum (m) value, that is, a value obtained by removing the directional information from the acceleration signal sensed by the second sensor and calculating only the magnitude, as shown in FIG. By correcting in consideration of the continuity, it is possible to determine the exercise section P3 using the acceleration information as shown in FIG.

The activity intensity may be calculated by removing the bias of the gravity momentum signal and taking an absolute value, and then calculating the standard deviation. For example, the activity intensity I may be calculated using Equation 4 below.

By correcting the continuity of the detected features, values as shown in FIGS. 5C and 5D can be obtained. In consideration of the continuity, the same method as the change in heart rate reduction may be applied. That is, when the time difference between the activity intensity calculated using the acceleration information and the activity intensity calculated next is less than the acceleration threshold section, it is determined to be continuous, and the activity intensity calculated using the acceleration information and the next calculated If the time between activity intensities exceeds the acceleration threshold, it may be judged as not continuous. As such, the correction may be performed using various techniques such as MM (Mathematical Morphology) and Moving Average.

When correcting in consideration of the continuity as described above, the exercise section P3 using the acceleration information is calculated, and the start point of the exercise section P3 can be determined as the start point of the exercise.

A method of finding a time point at which the heart rate starts to increase using the heart rate information will be described with reference to FIG. 6. In the case of FIG. 6, a time point at which the heart rate starts to increase may be found using the same method as described with reference to FIGS. 2 and 3. The method for finding a time point at which the heart rate starts to increase may include calculating a change in heart rate using heart rate information calculated from a signal detected by the first sensor, wherein the calculated change in heart rate is within a second critical section. The method may include determining and correcting whether the values are continuous values, and determining a time point at which the heart rate begins to increase using the corrected heart rate change amount as a start point of exercise. In the correcting step, when the time difference between the first time point in which the change in heart rate increase is within the second critical section and the second time point in which the change in heart rate increase is within the second critical section is less than or equal to a second reference time, And continuously correcting the change in heart rate to within the second critical section from the first time point to the second time point.

That is, in the case of FIG. 6, the heart rate increase amount may be used instead of the heart rate change amount, and a continuous section P4 in which the heart rate increases may be determined by correcting the continuity of the heart rate increase amount. In the case of FIG. 6, since the continuous section P4 may be determined by a method similar to FIGS. 2 and 3, the detailed description is replaced with the description related to FIGS. 2 and 3. When determining the continuous section P4 in which the heart rate increases as shown in FIG. 6, it is possible to determine a time point t10 at which the heart rate starts to increase.

The state in which the exercise section is determined by combining the above contents is shown in FIG. 7. Referring to FIG. 7, the period P5 from the time point t10 at which the heart rate starts to increase to the time point t2 at which the heart rate begins to decrease becomes an exercise section, and at a time point t9 at which the acceleration starts to increase. An interval P6 up to a time point t5 at which the heart rate starts to decrease may be an exercise section. Herein, the P5 section may be determined to be a corrective exercise section, and the P6 section may be determined to be a dynamic exercise section.

FIG. 9 is a diagram illustrating a case in which acceleration information and a threshold are compared according to the embodiment of FIG. 8, and FIGS. 10 and 11 are diagrams for describing a case in which an exercise section is determined according to the embodiment of FIG. 8. . Hereinafter, a method of determining an exercise section according to another exemplary embodiment of the inventive concept will be described with reference to FIGS. 1 to 11. Each step described below may be performed in a server or a computer, or may be performed in a device including the first sensor and the second sensor.

According to another aspect of the present invention, a method of determining an exercise section uses information detected by the first sensor and the second sensor in a state in which a device including a first sensor and a second sensor is coupled to a body. The exercise section can be determined by determining the start point and the end point of the exercise. The device that can be coupled to the body may be various devices such as a wearable device, a smartphone, the first sensor may be a sensor for obtaining heart rate information, and the second sensor may be a sensor for obtaining acceleration information. Can be. For example, the first sensor may be an optical volume pulse wave sensor capable of measuring plethysmography (PPG), and the second sensor may be a three-axis acceleration sensor capable of measuring an acceleration signal. However, if the first sensor of the present invention is a sensor capable of obtaining heart rate information, it may be another sensor in addition to the optical volume pulse wave sensor, and if the second sensor is a sensor capable of obtaining acceleration information, it may be another sensor in addition to the three-axis acceleration sensor. It may be.

In order to determine the exercise section, first, the acceleration information calculated from the signal sensed by the second sensor may be compared with the threshold value (S810). In FIG. 9, (a) is a graph showing heart rate information detected by the first sensor, and (b) is a graph showing acceleration information detected by the second sensor. A portion indicated by a dotted line in FIG. 9B corresponds to a case where the magnitude of the acceleration information is greater than or equal to the threshold value, and other portions correspond to a case where the magnitude of the acceleration information is less than the threshold value. In comparing the magnitude of the acceleration information with a threshold, the method described with reference to FIG. 5 may be used. That is, in the same manner as described with reference to FIG. 5, the continuity is corrected by comparing the magnitude of the acceleration information with a threshold value, and a section in which the magnitude of the acceleration information is greater than or equal to the threshold value and a section in which the magnitude of the acceleration information is less than the threshold value. Can be set.

As a result of the determination in step S810, when the magnitude of the acceleration information calculated from the signal detected by the second sensor is less than a threshold value, the exercise section may be determined using heart rate information calculated from the signal detected by the first sensor. (S830). In this case, in the same manner as described with reference to FIGS. 2 and 3, the time point at which the heart rate begins to decrease may be determined using the heart rate information calculated from the signal sensed by the first sensor. In addition, in the same manner as described with reference to FIGS. 4 and 6, the time point at which the heart rate starts to increase in the previous section of the exercise end time point may be determined as the exercise start time point. The specific method is replaced by the description of the associated drawings. The determined exercise section may be the P5 section of FIG. 10 and the P5 of FIG. 11.

Next, as a result of the determination in step S810, when the magnitude of the acceleration information is greater than or equal to the threshold value, the exercise section may be determined using the acceleration information, or the exercise section may be determined using the acceleration information and the heart rate information. (S820).

First, when the magnitude of the acceleration information is greater than or equal to the threshold value, a method of determining the exercise section or determining the exercise section using the acceleration information and the heart rate information will be described. In this case, in the same manner as described with reference to FIGS. 2 and 3, the time point at which the heart rate begins to decrease may be determined using the heart rate information calculated from the signal sensed by the first sensor. In addition, it is possible to determine, as the exercise start time point, the time when the acceleration starts to increase in the previous section of the exercise end time point in the same manner as described with reference to FIGS. 4 and 5. The specific method is replaced by the description of the associated drawings. The determined exercise section may be the P6 section of FIG. 10.

Next, a method of determining the exercise section using the acceleration information when the magnitude of the acceleration information is equal to or greater than the threshold value will be described. In the previous methods, the end point of the exercise was first determined by using the heart rate information, and then the start point of the exercise was found. However, the exercise section may be determined using only the acceleration information except the heart rate information. That is, as shown in FIG. 5, the start point to the end point of the section P3 in which the acceleration information is continuously displayed may be determined as the exercise section. Since the method for setting the section in which the acceleration information is continuously described has been described in detail with reference to FIG. 5, the description thereof is replaced with the description of FIG. 5. Accordingly, in FIG. 11, the exercise section in the section where the magnitude of the acceleration information is greater than or equal to the threshold is determined as P3.

As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, they are used only for the purpose of describing the present invention and are not intended to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
