After the number of times of detection of the predetermined body movement and the lapse of a predetermined time), the result information is configured and sent to the smartphone 100. Therefore, the recording memory 202 is configured to accumulate the detected values of the acceleration sensor 203, which will be described later, and temporarily store the result information configured based on the detected values. In the present embodiment, for the sake of simplicity, the sensor unit 200 of the present embodiment will be described as having a recording memory 202 in addition to the ROM for recording the operation program of each block of the sensor unit 200. The implementation of the invention is not limited to this.

The acceleration sensor 203 detects the movement generated in the sensor unit 200. In the present embodiment, the acceleration sensor 203 is configured to be capable of measuring acceleration in three axial directions. The three-axis directions to be measured may be formed in, for example, a right-handed system, and when the sensor unit 200 is installed on a horizontal plane, the Y-axis direction from the heel to the toes in the horizontal plane is in the same plane. It may be in the X-axis direction orthogonal to the Y-axis and in the Z-axis direction corresponding to the height direction.

It is assumed that it is configured to shift to a state where communication connection is possible according to the detection.

<< Presentation of evaluation of athletic ability >>
Hereinafter, the presentation of the evaluation of the motor ability of the subject, which is realized by executing the presentation application on the smartphone 100 in the presentation system of the present embodiment, will be described with reference to the figure.

In the presentation application of the present embodiment, the aptitude for a predetermined athletic competition is presented as an evaluation of the athletic ability of the subject. The presentation application includes, for example, a menu selection screen 400 as shown in FIG. 4, and the operation input related to the selection of the diagnosis menu 401 related to the sports diagnosis is made on the menu selection screen 400, so that the predetermined athletic competition The suitability for is presented.

The aptitude is based on the evaluation results derived by the evaluation unit 105 according to the distribution of the measured values related to the measurement results of the body movements of the subject acquired for a plurality of exercise items. Here, in the presentation application of the present embodiment, the body movement for which the measurement result is referred to for deriving the appropriateness is the body movement measured by the sensor unit 200 as the first type of body movement according to the present invention. And a second type of body movement, which is not measured by the sensor unit 200.

<First type of body movement>
First, the first type of body movement that can be measured by the sensor unit 200 of the present embodiment will be described.

As described above, the sensor unit 200 is configured to be capable of measuring a plurality of types of body movements (first type of body movements), and is a measurement target based on an item ID included in a measurement start request from the smartphone 100. When the exercise item of is determined, it is controlled to measure and record the corresponding physical movement only for a predetermined period. In the present embodiment, for example, the following six different motion items can be selected as measurement targets, and the measurement unit 204 outputs the acceleration sensor 203 according to which motion item is selected for measurement ( The axis for which the analysis of the waveform data) is analyzed is different, and the result information is constructed.
・ Quick reaction ・ Dash squat ・ Side agility ・ Back & go ・ Spring jump ・ Foot lift

For the measurement related to these motion items, the menu related to the measurement using the sensor unit 200 is selected in the presentation application (the operation input related to the selection of the measurement menu 402 is made on the menu selection screen 400), and then the measurement target is measured. By selecting the motion item, the measurement start request including the corresponding item ID is sent to the sensor unit 200, which is realized. That is, the presentation application is not limited to the use for presenting the suitability for athletics, which will be described later, and also has an aspect as a use for measuring the first type of body movement.

Here, the quick reaction refers to an exercise item for reaction speed training that measures the time required from the state in which the subject is stationary to the start of running in response to the start sound emitted by the smartphone 100. .. When the quick reaction is selected, the measuring unit 204 first advances from the timing at which the start sound is emitted by referring to, for example, the output waveform in the Y-axis direction among the waveform data output by the acceleration sensor 203. Measure the time it takes for the pattern to appear.

The dash squat is an exercise item for endurance training that measures the number of so-called in-situ steppings performed within a predetermined period. However, during the dash squat measurement period, an instruction notification to perform squat operation at random timing is sent, and the number of times is not counted even if additional stepping is performed on the spot until the squat operation is detected. Random. The measuring unit 204 measures and outputs the number of steps started after the start sound is emitted by referring to, for example, the output waveform in the Z-axis direction in the waveform data output by the acceleration sensor 203.

Side agility refers to an exercise item for agility training that measures the number of so-called repeated side jumps performed within a predetermined period of time. The measuring unit 204 measures the number of times a jump pattern appears in the Z-axis direction after the start sound is generated by referring to, for example, the output waveform in the Z-axis direction among the waveform data output by the acceleration sensor 203. do. It should be noted that the rule of counting as one time when the acceleration direction in the X-axis direction is different between the first time and the second time may be used to measure the number of repeated side jumps. In addition, for the purpose of reducing the load of data calculation and simplifying data processing, the Z-axis is assumed to be moving left and right for the target person, that is, moving in the X-axis direction. The number of jumps performed may be measured by referring only to the output waveform in the direction.

Back & go refers to an exercise item for core stability training that measures the number of jumps in the anterior-posterior direction alternately performed within a predetermined period. The measuring unit 204 refers to, for example, the output waveforms in the Y-axis direction and the Z-axis direction among the waveform data output by the acceleration sensor 203, and after the start sound is generated, a jump pattern appears in the Z-axis direction. The number of jumps is counted, and the number of jumps is measured by the rule of counting each time because the acceleration direction in the Y-axis direction is different between the odd number and the even number. For the purpose of reducing the load of data calculation and simplifying data processing, it is assumed that the target person is moving in the front-back direction, that is, moving in the Y-axis direction. It may be a rule that only the output waveform in the axial direction is referred to, and the appearance of two jump patterns in the Z-axis direction is counted as one time.

Spring jump is an exercise item for training jumping force that measures the flight time during jumping. The measuring unit 204 refers to, for example, the output waveform in the Z-axis direction among the waveform data output by the acceleration sensor 203, and starts when a pattern related to one jump appears after the start sound is emitted. Measure the time from to the end.

The foot lift is an exercise item for leg strength training that measures the number of so-called thigh lifts performed within a predetermined period. The measuring unit 204 refers to, for example, the output waveform in the Z-axis direction among the waveform data output by the acceleration sensor 203, and determines the number of times the walking pattern appears in the Z-axis direction after the start sound is generated. Count.

As described above, the sensor unit 200 of the present embodiment is limited to a part of the axes measured by the acceleration sensor 203 so that the calculation load can be reduced regardless of the motion item, and the obtained waveform data is obtained. Make measurements based on. However, the implementation of the present invention is not limited to this, and the measurement may be performed based on the waveform data obtained for all three axes without being limited to some axes.

The measurement unit 204 generates result information based on the measurement result obtained in this way and records it in the recording memory 202. In the smartphone 100 of the present embodiment, the result information generated by the measuring unit 204 is received, stored as history data, and used for deriving the evaluation result. Here, as shown in FIG. 9, the result information is associated with the identification information 901 that identifies the result information (for example, a time stamp, etc.), and the item ID 902 indicating which of the measured exercise items is, and the measurement. It may be configured to include the result 903. The result information is configured on the condition that the measurement end condition is satisfied, is recorded in the recording memory 202, and then is sent to the smartphone 100 which is in communication connection at a predetermined timing. The result information received by the smartphone 100 is accumulated in the history data recorded in the recording medium 102 as described above, and at least the best (highest evaluation of physical ability / best body) for each exercise item. It is assumed that the measurement results (indicating the ability) are configured for reference.

<Second type of physical movement>
Next, a second type of body movement that is not measured by the sensor unit 200 of the present embodiment will be described.

The second type of physical movement is not measured using the presentation application and the sensor unit 200, but is intended, for example, an exercise item specified in the so-called "new physical fitness test" specified by the Ministry of Education, Culture, Sports, Science and Technology. It shall be an exercise item for which the person can obtain the measurement result separately. Therefore, in the presentation application of this embodiment for the new physical fitness test, grip strength, upper body raising, long-distance forward bending, repeated side jump, 20m shuttle run (round-trip endurance running), 50m run, standing width jump, softball Eight types of ball throws correspond to the second type of physical movement. That is, the second type of body movement is not necessarily measured with the athletic shoe 300 (sensor unit 200) attached.

Regarding the exercise items related to the second type of body movement, the information input is configured so that numerical values can be input prior to the derivation of the appropriateness on the setting screen 500 of the presentation application as shown in FIG. However, it is assumed that the data is recorded on the recording medium 102 separately from the historical data related to the measurement result of the sensor unit 200.

The presentation application of the present embodiment is configured to be able to derive the aptitude based on the measurement results of these two types of body movements, and the measurement result is input for the second type of body movements. Is not required. The more exercise items that have measurement results, the more accurate the evaluation is possible, but the new physical fitness test is conducted only at a specific time of the year, and too much time has passed since the latest implementation. If so, the measurement results may not properly indicate the motor ability of the subject, the test itself may not be performed, or the subject may not be able to participate in the test. Therefore, in the presentation application of the present embodiment, although it is notified that a highly reliable aptitude can be derived if there is an input for the measurement result of the second type of body movement, the input is not essential. Treat as not.

On the other hand, in order to ensure a certain degree of reliability regarding the derived aptitude, it is the aptitude that measurement results are obtained for all (the above 6 types) exercise items for the first type of body movement. It is assumed that it is required for the derivation of.

Then, the measurement result of the physical movement of the subject obtained for each of the plurality of exercise items is ranked in 5 stages (rank having an integer of 1 to 5 (rank 1 indicates the lowest physical ability, and the rank number). The larger the value, the better the physical ability (measurement result indicating excellent athletic ability) is shown). Based on the distribution of the measured values of, the evaluation result, the suitability for the predetermined athletic competition of the subject, is derived. The conversion to the measured value is performed based on the information of which measured value is used for each value range of the measurement result specified in the predetermined look-up table pre-recorded on the recording medium 102 for each exercise item. It may be something that can be seen.

At this time, if there is no measurement result for the second type of body movement, the acquisition unit 104 sets the average value of the measured values of all the exercise items related to the first type of body movement to the second type. Substitute as the measured value of all exercise items related to the physical movement of. That is, when the measurement result for the second type of body movement is not input, the acquisition unit 104 is assumed to be obtained (complemented) with the same measured value (not limited to an integer). handle.

Prescribed athletics include 16 types of athletics, such as baseball, soccer, volleyball, basketball, tennis, table tennis, golf, land, swimming, HIPHOP dance, cheer dance, badminton, gymnastics, karate, kendo, and judo. The evaluation unit 105 derives the aptitude of the subject for each of these athletics. Further, when the measurement result for the second type of body movement is input (when the average value of the measured values for the first type of body movement is not substituted), the evaluation unit 105 is assigned to this. In addition, further types of athletics such as long-distance running, skiing / snowboarding, and biking (hereinafter referred to as extended athletics, which are distinguished from the above 16 types of athletics from which aptitude is basically derived). , It may be configured so that the aptitude of the subject can be derived. This is because the more types of exercise items for which measurement results exist, the more the evaluation can be made according to the characteristics of various athletic sports.

In the application for presentation of the present embodiment, the measured values of a plurality of exercise items (6 types of exercise items related to the first type of body movement + 8 types of exercise items related to the second type of body movement = 14 types in total) are measured. In order to make it easier for the subject to grasp the athletics that match the tendency of distribution, the suitability for each athletics is predetermined for the distribution of the measured values and multiple exercise items related to each athletics to be evaluated. Derived based on the correlation with the distribution of evaluation reference values. The distribution of the evaluation reference values is the tendency of evaluation of each exercise item required for each of the athletics to be evaluated, for example, the athlete of the athletics, and the threshold value for judging to show good results and aptitude for the athletics. It may be composed of a combination of ranks of 14 kinds of exercise items determined based on statistics obtained from various samples, and may be stored in the recording medium 102 in advance. That is, the distribution of the evaluation reference values related to one type of athletics is configured to include information indicating which rank is for each of the 14 types of exercise items, similar to the distribution of the measured values. In other words, for one type of exercise item, an evaluation reference value is set for each of the plurality of types of athletic competitions to be evaluated.

を導出し、該相関係数に基づいて評価結果（適性度）を得る。ここで、複数の運動項目には固定の整数値ｉ（最大値Ｎ＝１４）が割り当てられており、Ｘ_iは整数値ｉで識別される運動項目の測定値、Ｙ_iは同運動項目の評価基準値を示しており、分母項はＸの標準偏差とＹの標準偏差の積、分子項はＸとＹの共分散を示している。即ち、評価部１０５による評価では、複数の運動項目の測定値の分布と類似する評価基準値の分布を示す運動競技について、相関が高いとの評価結果が得られることになり、これに基づいて適性度が導出される。 For each athletic sport to be evaluated, the evaluation unit 105 has a correlation coefficient r between the distribution of the evaluation reference value and the distribution of the measured value determined for the athletic sport.

Is derived, and an evaluation result (aptitude) is obtained based on the correlation coefficient. Here, a fixed integer value i (maximum value N = 14) is assigned to a plurality of exercise items, X _i is a measured value of the exercise item identified by the integer value i, and Y _i is the same exercise item. The evaluation reference value is shown, the denominator term shows the product of the standard deviation of X and the standard deviation of Y, and the molecular term shows the covariance of X and Y. That is, in the evaluation by the evaluation unit 105, it is possible to obtain an evaluation result that the correlation is high for the athletic competition showing the distribution of the evaluation reference values similar to the distribution of the measured values of a plurality of exercise items, and based on this. The aptitude is derived.

In the presentation application of the present embodiment, in order to present the aptitude for the athletics that the subject wishes to evaluate, for example, one of the above 16 types of athletics that wants to present the aptitude in the evaluation. The designation of athletics shall be accepted. On the other hand, since it is also preferable to configure it so that the subject can be notified of the aptitude for the athletics that he / she is not aware of, the evaluation unit 105 evaluates the distribution of the measured values obtained for the subject. Derives aptitude not only for the designated athletics, but also for other athletics. That is, the evaluation unit 105 determines the distribution of the measured values and the evaluation reference values for all the athletics (16 types of athletics + extended athletics described above) that can be evaluated by the presentation application, including the designated athletics. Derivation of the correlation coefficient related to the distribution. In the present embodiment, for the sake of simplicity of explanation, the evaluation unit 105 will be described as deriving the aptitude for all evaluable athletic sports, but the implementation of the present invention is not limited to this. For example, the derivation of the aptitude for the extended athletic competition may be configured so as to be performed only when the measurement result of the exercise item related to the second type of physical movement is input.

In this embodiment, the aptitude of the subject to a predetermined athletic competition (evaluation result of athletic ability) is derived based on the correlation coefficient obtained for the distribution of the measured value and the distribution of the evaluation reference value. However, the implementation of the present invention is not limited to this. For example, the derivation of the correlation of these distributions does not have to be based on the correlation coefficient. Further, for example, the derivation of the aptitude by the evaluation unit 105 is not limited to the one based on the correlation, but may be performed based on the similarity of these distributions or other relationships.

Further, in the present embodiment, for the sake of simplicity, the distribution of the evaluation reference values related to one type of athletics will be uniquely defined, but the implementation of the present invention is limited to this. is not. That is, since the degree of improvement in athletic ability related to each exercise item can change depending on age and gender, it is not possible to make an appropriate evaluation according to age, for example, in the distribution of uniquely determined evaluation reference values. Not exclusively. Therefore, for example, the distribution of the evaluation reference values shall be provided for each combination of age and gender, and the evaluation unit 105 acquires the distribution of the corresponding evaluation reference values based on the information of the age and gender acquired for the subject. It may be evaluated.

By the way, as described above, the evaluation based on the correlation, the degree of similarity, etc. may deviate from the subjective evaluation held by the subject regarding the measurement result of each exercise item. For example, in two of the 14 types of exercise items, measurement values exceeding the evaluation reference value (measurement values based on the measurement results showing excellent athletic ability) are obtained, and the remaining items are the same measurement as the evaluation reference value. When the value is obtained, the correlation is lowered due to the measured value exceeding the evaluation standard value even though the distribution shows the measured value equal to or higher than the evaluation standard value for all the exercise items. .. That is, from the viewpoint of "correlation", even if the measured values indicating excellent athletic ability are included, the evaluation results may not be good, and the evaluation results that reduce the subject's willingness to exercise are presented. obtain.

Therefore, in the presentation application of the present embodiment, the adjusting unit 106 adjusts the evaluation result (adjustment of the aptitude) with respect to the existence of the measured value indicating the exercise ability superior to the evaluation reference value. More specifically, the adjusting unit 106 adjusts the evaluation result upward according to the number of exercise items whose measured value exceeds the evaluation reference value among the 14 types of exercise items. Since the correlation coefficient is derived in the range of -1 to +1. May be evenly divided and an adjustment of +0.3 may be made when the measured value exceeds the evaluation reference value in one exercise item. That is, the value of the evaluation result after adjustment is derived in a range (-1 to +2.8) wider than the correlation coefficient.

In the present embodiment, it is described that the value of the evaluation result is adjusted upward by adding a fixed value according to the number of exercise items whose measured value exceeds the evaluation reference value. Not limited. The upward adjustment may be performed when the measured value is a value indicating an athletic ability superior to the evaluation reference value, and the adjustment mode may be, for example, by adding or multiplying a number according to the difference. It may be done. Alternatively, in an embodiment in which the evaluation by the evaluation unit 105 is performed according to the similarity between the distribution of the measured values and the distribution of the evaluation reference values, the adjustment may be performed according to the degree of deviation of these distributions. Here, the adjustment due to the existence of a measured value indicating an athletic ability superior to the evaluation reference value causes the measurement result of the excellent athletic ability to not appear in the evaluation result or makes the evaluation result unsuitable. Since this is done to solve the problem, for example, even if there is a measured value that is less than the evaluation reference value, it may be controlled so that the downward adjustment based on the measured value is not performed.

In addition, when the evaluation is performed based on the correlation between the distribution of the measured values and the distribution of the evaluation reference values, the tendency of the distribution is the distribution of the evaluation reference values even if the measured values are distributed lower than each evaluation reference value as a whole. If it is the same as, the correlation becomes high, and as a result, there is a possibility that an evaluation result that deviates from the reality is derived. For example, even if the measured value of any exercise item is lower than the evaluation standard value, if the ratio of the evaluation standard value and the measured value related to each exercise item is the same, the correlation becomes high, so that the measurement result On the contrary, the evaluation result indicating that the suitability for the relevant athletic competition is high is derived.

Therefore, in the presentation application of the present embodiment, the adjusting unit 106 further adjusts the evaluation result with respect to the distribution of such measured values. More specifically, the adjusting unit 106 adjusts the value of the evaluation result by adding the values determined according to the average value of the measured values of the 14 types of exercise items or by integrating the coefficients. Since the purpose of the adjustment is to adjust the evaluation result that can show high aptitude contrary to the measurement result, both the downward adjustment and the upward adjustment shall be included.

By doing so, the adjusting unit 106 of the present embodiment adjusts the evaluation result derived by the evaluation unit 105 so as to be in accordance with the measurement result and to appropriately stimulate the subject's motivation for exercise. Can be done.

The evaluation result adjusted by the adjustment unit 106 (hereinafter referred to as the adjusted evaluation result) is obtained by displaying the result presentation screen 600 as shown in FIG. 6 on the display unit 110 by the presentation control unit 107, for example. , Presented to the subject. As shown, the result presentation screen 600 includes an athletic sport name 601 indicating an athletic sport designated by the subject and an aptitude 602 corresponding to the adjusted evaluation result derived for the athletic sport. .. In the example of FIG. 6, the aptitude degree 602 corresponding to the adjusted evaluation result is presented as the number of colored stars in eight ranks in which the adjusted evaluation result values are distributed according to a predetermined threshold value (colored stars). The higher the number or rank, the higher the aptitude).

Further, in the example of FIG. 6, the result presentation screen 600 includes a comparison chart 603 showing the distribution 604 of the measured values and the distribution 605 of the evaluation reference values for the exercise items related to the first type of body movement. The comparison chart 603 is shown in the form of a radar chart in which the measured value and the evaluation reference value can be compared, and the subject can easily grasp which exercise item should be trained or measured.

Further, in the presentation application of the present embodiment, the evaluation unit 105 and the adjustment unit 106 derive and adjust the evaluation results for each of the evaluable athletics based on the distribution of the measured values obtained for the subject. Therefore, it is possible to present the appropriateness for athletics other than the athletics designated by the subject. The aptitude for athletics other than the designated athletics is present on the result presentation screen 600, for example, when there is an athletics showing an aptitude above a predetermined threshold (indicating a predetermined number or more of ranks). The target person may be notified by presenting the notification 606 including the notification 606. Then, when the operation input to the notification 606 is detected, the presentation control unit 107 shifts from the result presentation screen 600 to the other aptitude presentation screen 700 as shown in FIG. 7, and is equal to or higher than a predetermined threshold value on the screen. The athletic competition showing the aptitude of the above and its aptitude are presented.

In the example of FIG. 7, athletic sports showing aptitude of rank 6 or higher are basically arranged and presented in descending order of aptitude. Considering the frequency of measurement opportunities, the measurement results of the exercise items related to the second type of physical movement may differ from the exercise ability of the subject at the time of evaluation, so an example of the other aptitude presentation screen 700. Then, in the extended exercise competition in which the input of the measurement result of the exercise item related to the second type of physical movement is a requirement for evaluation, it is lower than the 16 types of exercise competition in which the input of the measurement result is not a requirement for evaluation. The order is assigned and presented. Further, in the athletics included in the 16 types of athletics, a turning button 701 capable of accepting an operation input related to a change in the designation of the target person is presented.

Although not specified in the present embodiment, the athletic sport is described as being notified on the condition that the rank of aptitude is equal to or higher than a predetermined threshold value, the implementation of the present invention is not limited to this. The condition of the athletic competition to be notified may be determined for the adjusted evaluation result, and may be any of the conditions, for example, the condition that the rank of aptitude is higher than that of the previous evaluation.

Further, prior to the present presentation process, one of the 16 types of athletics desired by the subject can be evaluated without the need to input the measurement results of the exercise items related to the second type of physical movement. (Designated athletics) is designated, and it is assumed that the information of the designated athletics is stored in, for example, the memory 103.

In S801, the acquisition unit 104 acquires the measured value used for the evaluation based on the information of the measurement result related to each exercise item under the control of the control unit 101. At this time, the acquisition unit 104 identifies the best measurement result among the measurement results recorded in the history data related to each exercise item for the exercise item related to the first type of body movement, and sets each exercise item. The measured value (rank value) corresponding to the measurement result is acquired by referring to the lookup table. Further, for the exercise item related to the second type of body movement, the acquisition unit 104 similarly measures the measurement value based on the measurement result when the corresponding measurement result is input and stored in the recording medium 102. To get. On the other hand, when the corresponding measurement result is not input, the acquisition unit 104 derives the average value of the measurement value group obtained for the exercise item related to the first type of body movement, and derives the average value of the measurement value group of the second type. Handled as a measured value of exercise items related to physical movement (assumed to be acquired).

In S802, the evaluation unit 105, under the control of the control unit 101, is based on the distribution of the measured values acquired in S801 and the distribution of the evaluation reference values related to the athletic competition for each of the plurality of types of athletics that can be evaluated. Therefore, the correlation coefficient, which is the evaluation result, is derived and stored in the memory 103. By the processing of this step, the value of the correlation coefficient is stored in the memory 103 as the evaluation result for all kinds of athletic sports that can be evaluated.

In S803, the adjusting unit 106 derives various adjustment values of the evaluation results stored in S802 under the control of the control unit 101, and adjusts the evaluation results based on the adjustment values. More specifically, the adjusting unit 106 counts the number of exercise items showing a measured value exceeding the evaluation reference value for each of the evaluable athletics, and derives an adjusting value according to the number. Further, the adjustment unit 106 derives an adjustment value based on the average value of the measured values. Then, the adjustment unit 106 adjusts the evaluation result of each athletic competition based on the derived adjustment value.

In S804, under the control of the control unit 101, the presentation control unit 107 configures a result presentation screen based on the evaluation result adjusted in S802 and causes the display unit 110 to present the result, and completes the present presentation process.

As described above, according to the presentation system of the present embodiment, it is possible to present the evaluation result of the athletic ability that appropriately stimulates the exercise motivation of the subject.

[Modification 1]

An additional element is provided for the measurement of the motion item related to the motion, and the adjusting unit 106 is configured to perform upward adjustment based on the total score of a predetermined period until the instruction input related to the evaluation of the aptitude is made. The adjustment may be performed based on, for example, a determination as to whether or not the total score exceeds a predetermined threshold value. Here, the threshold value may be set for the entire period such as the last week, or a part of any one day of the last week or the like so that the subject's motivation for exercise is further promoted. It may be set for a specific period. Further, the point addition element may be one in which a fixed score is added according to the number of measurements, or may be one in which a variable score is added according to the measurement result.

In addition to these points, adjustments are made according to the measurement frequency (training frequency) of exercise items related to the first type of physical movement and the usage frequency (execution / activation frequency) of the presentation application. May be. For example, if the training frequency or the frequency of use of the presentation application exceeds a predetermined threshold value, the upward adjustment may be performed, and if the training frequency or the presentation application is used below the threshold value, the downward adjustment may be performed. In the latter case, it is expected that the subject's motivation for exercise will be stimulated by forcibly lowering the aptitude from the value based on the previous evaluation.

These adjustments (point addition factors and frequency) may be introduced either one or both.
