[0003] [Patent Document 1] Patent Publication No. 2021-81864 Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, it has been recognized that it is good to exercise at a certain intensity to suppress or improve the decline of brain function, such as suppressing or improving the progression of dementia. However, ordinary users do not know what kind of exercise they should do to suppress or improve their own brain function, and as a result, the exercise that the user performs on his or her own for the purpose of suppressing or improving the decline of brain function may be insufficient or inappropriate. In addition, since the user is not sure whether it is appropriate, there is a risk that the user will stop exercising continuously. Such a situation is not good for users who want to suppress or improve the decline of brain function.

[0005] Therefore, one of the objectives of the present disclosure is to provide a brain function improvement promotion device that can easily promote the inhibition of decline and improvement of brain function appropriate for the user.

[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The brain function improvement promotion device according to the present disclosure is wearable on the user's body and promotes the improvement of the user's brain function. The brain function improvement promotion device includes a storage unit for storing data, a display screen for displaying data, a time measurement unit for measuring time, a brain function improvement contributing exercise intensity measurement unit for measuring over time a brain function improvement contributing exercise intensity, which is an exercise intensity that contributes to the improvement of the user's brain function, a target brain function improvement contributing exercise intensity calculation unit for calculating a target brain function improvement contributing exercise intensity set as a target exercise intensity necessary for the user to promote the improvement of the brain function and a target time to be reached within a predetermined time limit, a setting unit for setting the target brain function improvement contributing exercise intensity and target time calculated by the target brain function improvement contributing exercise intensity calculation unit, a first judgment unit for judging whether the brain function improvement contributing exercise intensity of the user measured by the brain function improvement contributing exercise intensity measurement unit has reached or exceeded the target brain function improvement contributing exercise intensity set by the setting unit, and a judgment unit for judging whether the brain function improvement contributing exercise intensity of the user measured by the brain function improvement contributing exercise intensity measurement unit has reached or exceeded the target brain function improvement contributing exercise intensity set by the setting unit. The brain function improving exercise intensity control unit includes a duration measurement control unit that controls the time measurement unit to measure a duration that is equal to or longer than the target brain function improving contributing exercise intensity, a second judgment unit that judges whether the total duration measured within a specified period of time has reached the target time set by the setting unit, a memory control unit that controls the memory unit to store information that the total duration has reached the target time if the second judgment unit judges that the total duration has reached the target time, a display data generation unit that generates display data that displays data based on the reaching of the target time on a display screen if the second judgment unit judges that the total duration has reached the target time, and a display control unit that controls at least one of the target brain function improving contributing exercise intensity, actual related data and time calculated by the target brain function improving contributing exercise intensity calculation unit, and the display data generated by the display data generation unit to be displayed on the display screen.

[0010] The present inventors have focused on the fact that exercise of a certain intensity is effective for suppressing the decline of a user's brain function or improving the user's brain function, including suppressing the progression of dementia or improving dementia. The user then tries to exercise for a long time, such as running, in order to improve brain function. Here, running is taken as an example of exercise of a certain intensity. Aerobic exercise such as monotonous running is relatively hard exercise, and it is often difficult to continue. In fact, the present inventors have considered that even if the running is not performed at such a high intensity, it is often effective for suppressing the decline of brain function or improving brain function, as long as it is performed continuously. Therefore, when performing exercise, it is considered important to clarify the target exercise intensity that is necessary or desirable for suppressing the decline of brain function or improving brain function. In this specification, from the viewpoint of facilitating explanation, suppression of decline of brain function is included in the concept of improving brain function. Here, the present inventors have focused on the fact that even if the user does not consciously perform hard exercise such as running, there is exercise that meets such a target exercise intensity in everyday life. We further focused on the fact that exercise that meets this target exercise intensity may be performed, for example, when walking a dog, walking briskly on the way to work, or walking up stairs, etc. We thought that by making the user aware that brain function is improved by this exercise in everyday life (regardless of whether it is so-called aerobic exercise or anaerobic exercise), we could have the user continue to perform exercise that meets the target exercise intensity, whether they are consciously exercising to improve brain function, exercising for other purposes such as maintaining or improving health, or even in everyday life without any special awareness, and as a result, we could effectively promote the improvement of brain function.

[0011] The inventors further considered the following. Exercise that satisfies the target exercise intensity necessary or desirable for the user to promote brain function improvement is a balance between the target brain function improvement contributing exercise intensity, which is the target of the index value of the exercise intensity that contributes to the improvement of the user's brain function, and the target time. That is, the target brain function improvement contributing exercise intensity can be set with a certain degree of range while being set according to the user's attributes, etc., and it is said that the higher the target brain function improvement contributing exercise intensity, the more effective it is for promoting brain function improvement. On the other hand, the higher the target brain function improvement contributing exercise intensity, the harder the exercise, so that depending on the user, it may be difficult to perform it continuously or without interruption. If it becomes difficult to perform it continuously or without interruption, or in some cases it is not continued, not only will the effect of improving brain function be reduced, but it may become completely meaningless.

[0012] According to the brain function improvement promotion device, the brain function improvement promotion device attached to the user's body measures the user's brain function improvement contributing exercise intensity over time, measures the duration when the exercise intensity is equal to or greater than the target brain function improvement contributing exercise intensity, and if the target time to be reached within a specified time limit is reached, displays the fact on the display screen. In addition, by starting the brain function improvement promotion device, the target brain function improvement contributing exercise intensity and target time set as the target exercise intensity required or desirable for the user to promote brain function improvement can be calculated, and the target exercise intensity can be displayed on the display screen. In this way, it is possible to visually confirm on the display screen that exercise of a certain exercise intensity that leads to improvement of brain function has been performed in everyday life. Therefore, it is possible to realize that exercise of a certain exercise intensity that leads to improvement of brain function has been performed without difficulty in everyday life. In other words, even if the user does not actively go to a sports gym or the like to perform a certain exercise such as running, he or she can realize that he or she is performing exercise of a certain exercise intensity that leads to improvement of brain function. Of course, the brain function improvement promotion device is utilized whether the user consciously exercises to improve brain function or exercises to maintain or improve other health. Specifically, in order to clarify the target exercise intensity required or desired for promoting brain function improvement when performing such exercise, the target brain function improvement contributing exercise intensity and target time can be calculated and the target exercise intensity can be displayed on the display screen. This allows the user to continuously perform exercise that leads to improvement of brain function without having to perform excessively hard exercise. In addition, since the display screen allows the user to understand that he or she has performed a certain exercise that is effective for improving brain function, the user can strive to perform exercise that meets the target exercise intensity even in everyday life without any special awareness, which can lead to the promotion of improvement of brain function. As described above, according to such a brain function improvement promotion device, it is possible to easily promote improvement of brain function appropriate for the user.

[0013] In the brain function improvement promotion device, the second judgment unit may judge whether the duration has reached a first set time that is shorter than the target time if it is not judged that the duration has reached the target time. The memory control unit may control the memory unit to store the fact that the first set time has been reached if the second judgment unit judges that the duration has reached the first set time. The display data generation unit may generate display data for displaying data based on the reaching of the first set time on the display screen if the second judgment unit judges that the duration has reached the first set time. By doing so, if the duration has reached the first set time even if it does not reach the target time, the user can easily visually recognize that the duration has reached the first set time. If the duration does not reach the target time and it is useful to store and display the duration for promoting the improvement of brain function, multiple set times may be set, such as a second set time and an Nth set time (N is an integer of 3 or more), in addition to the first set time. Therefore, by effectively setting the set time so as to approach the target time, and storing and displaying the duration, it is possible to encourage the user to continue or uninterruptedly perform a similar constant exercise in everyday life, which can lead to the promotion of the improvement of brain function. In addition, the first set time, the second set time, or the Nth set time may be a time that is the minimum value that can be observed as a unit of time measurement (here, minutes or seconds) such as 1 minute or 1 second, as long as it is observable. In addition, by adding the first set time, the second set time, or the Nth set time together, it is possible to gradually approach the target time that should be reached within a specified time limit, which is an effective target time that leads to improvement of brain function.

[0014] In the brain function improvement promotion device, the memory control unit may control the memory unit to store the data of the duration when the second judgment unit judges that the duration has reached the first set time. By doing so, even if the duration does not reach the target time, the duration is added up and displayed, etc., so that it is possible to visually appeal to the user that an effective exercise that leads to the improvement of brain function has been performed. Therefore, it is possible to promote the improvement of brain function through exercise within a specified time period.

[0015] In the brain function improvement and promotion device, the improvement of brain function may include at least one of suppressing the progression of dementia, suppressing brain atrophy including negative changes in brain morphology, and improving brain health score. The above-mentioned certain exercise is very effective in suppressing the progression of dementia, suppressing brain morphological atrophy including negative changes in brain morphology, and improving brain health score.

[0016] In the brain function improvement promotion device, the display data generation unit may generate display data to display that fact if the first judgment unit does not judge that the brain function improvement contributing exercise intensity of the user measured by the brain function improvement contributing exercise intensity measurement unit becomes equal to or greater than the target brain function improvement contributing exercise intensity within a certain period from a predetermined timing measured by the time measurement unit. By doing so, it is possible to visually appeal to the user that the user has not performed exercise that will result in a brain function improvement contributing exercise intensity equal to or greater than the target brain function improvement contributing exercise intensity for a certain period. Therefore, it is possible to encourage the user to perform exercise in daily life that will result in a brain function improvement contributing exercise intensity equal to or greater than the target brain function improvement contributing exercise intensity.

[0017] In the brain function improvement promotion device, the judgment by the first judgment unit may be refreshed at a predetermined timing. In this way, it is possible to effectively promote repeated constant exercise over a short period such as one week or a long period such as several months.

[0018] In the brain function improvement promotion device, the target brain function improvement contributing exercise intensity calculation unit may calculate the target brain function improvement contributing exercise intensity using at least one of the Rule-based model, the machine learning model, and the deep learning model. In this way, it is possible to calculate a target brain function improvement contributing exercise intensity that is more meaningful to the user, and it is possible to easily promote the improvement of brain function that is more appropriate for the user. In this case, the calculation may be performed using one of the Rule-based model, the machine learning model, and the deep learning model, or the target brain function improvement contributing exercise intensity may be calculated using a combination of the Rule-based model and the machine learning model, a combination of the Rule-based model and the deep learning model, or a combination of the machine learning model and the deep learning model, or the target brain function improvement contributing exercise intensity may be calculated using a combination of the Rule-based model, the machine learning model, and the deep learning model. Of course, the target brain function improvement contributing exercise intensity may be calculated using a combination of one of the Rule-based model, the machine learning model, and the deep learning model and one or more other methods.

[0019] In the above-mentioned brain function improvement promotion device, the target brain function improvement contributing exercise intensity calculation unit may calculate as the target brain function improvement contributing exercise intensity an optimized target brain function improvement contributing exercise intensity, which is the highest possible brain function improvement contributing exercise intensity while satisfying the condition of performing exercise continuously or uninterruptedly.

[0020] In order to maximize the effect of improving brain function for the user, it is useful to set the target brain function improving exercise intensity as high as possible while satisfying the condition of performing exercise continuously or without interruption. Setting of such target brain function improving exercise intensity varies for each individual depending on factors such as the user's age, sex, exercise experience (which may be short-term, medium-term, or long-term experience), physical ability, motivation, etc.

[0021] Therefore, the inventors have found that "setting the highest possible target brain function improvement contributing exercise intensity while satisfying the condition of performing exercise continuously or uninterruptedly" is effective in maximizing the effect of brain function improvement, and have devised a method for determining the target brain function improvement contributing exercise intensity suitable for each individual user, depending on factors such as the user's age, sex, exercise experience, physical ability, motivation, etc. These are applied to the brain function improvement promotion device, and also to the brain function improvement promotion system, brain function improvement promotion method, brain function improvement promotion program, and recording medium, all of which will be described later.

[0022] This "target exercise intensity that contributes to improving brain function as high as possible while satisfying the condition of performing the exercise continuously or without interruption" is defined as the "optimized target exercise intensity that contributes to improving brain function."

[0023] The optimized target brain function improvement contributing exercise intensity for a certain user is calculated by a target brain function improvement contributing exercise intensity calculation unit by inputting qualitative or quantitative information including the following (1) and (2).

[0024] (1) Information obtained by the target brain function improvement contributing exercise intensity calculation unit is: (a) the user's target brain function improvement contributing exercise intensity;

[0025] (2) The information obtained by the user's input is (a) the target time for exercising if the user is going to exercise, and (b) the user's goal or preference level for the exercise intensity of that exercise (hereinafter referred to as "user preference level", sometimes expressed as "Pi"). According to such a brain function improvement promotion program, it is possible to easily promote improvement of brain function appropriate for the user.

[0026] The user preference (Pi) may be presented as a plurality of objective numerical values ​​(e.g., a percentage such as "80%" when exercising at full strength) by the target brain function improvement contribution exercise intensity calculation unit. Alternatively, the user preference (Pi) may be a method in which the user selects from a plurality of subjective options (e.g., five levels such as highest, high, medium, low, and easy). In this case, the target brain function improvement contribution exercise intensity calculation unit converts the subjective options into an appropriate objective numerical value using a predetermined formula.

[0027] Information other than the information in (1) and (2) may be input as information for calculating the optimized target brain function improvement contributing exercise intensity. For example, the user's age or sex may be input from the target brain function improvement contributing exercise intensity calculation unit, the user's sleep time last night and other health care data may be input from the device, or the user may input evaluation information regarding today's physical condition.

[0028] The optimized target brain function improving exercise intensity is an exercise intensity that contributes to improving brain function and satisfies all of the following (3), (4), and (5).

[0029] (3) The exercise intensity is equal to or greater than the brain function improvement-contributing exercise intensity necessary for promoting improvement of brain function for the user.

[0030] (4) The brain function improvement contributing exercise intensity is such that the brain function improvement contributing exercise intensity can be kept constant during the duration (expressed as X minutes, for example, 35 minutes). This "constant" is a concept with a certain degree of breadth, and for example, it means maintaining a brain function improvement contributing exercise intensity that falls within a range of 95% to 105% of the brain function improvement contributing exercise intensity set as the optimization target brain function improvement contributing exercise intensity. For example, if the optimization target brain function improvement contributing exercise intensity is 80, the brain function improvement contributing exercise intensity is said to be constant if it is between 76 and 84.

[0031] (5) The brain function improvement contributing exercise intensity is obtained by multiplying the “exercise intensity” in the calculation formula for the “target brain function improvement contributing exercise intensity” by an “objective numerical value” that corresponds to the user preference (Pi).

[0032] As a formula model for determining the optimized target brain function improvement contributing exercise intensity, which constitutes the target brain function improvement contributing exercise intensity calculation unit, various methods such as a rule-based model, a machine learning model, a deep learning model, etc. can be used.

[0033] In the case of the rule-based model, calculation rules for the optimization target exercise intensity that contributes to improving brain function are defined based on existing research results and knowledge in sports medicine and science, etc., and the optimization target exercise intensity that contributes to improving brain function is predicted based on these rules.

[0034] In machine learning models, methods such as support vector machines (SVM), decision trees, random forests, and K-nearest neighbor methods can be used. In deep learning models, methods such as multi-layer neural networks (MNN), recurrent neural networks (RNN), long short-term memory networks (LSTM), convolutional neural networks (CNN), and transformers can be used. These methods provide data consisting of input and output, perform supervised learning, and optimize the parameters of the model, outputting the "optimized target brain function improvement contributing exercise intensity," which is the highest possible target brain function improvement contributing exercise intensity while satisfying the condition of continuous or uninterrupted exercise.

[0035] The formula for calculating the above-mentioned optimized target brain function improvement contributing exercise intensity, which constitutes the target brain function improvement contributing exercise intensity calculation unit, is learned and changed to optimize the user's target brain function improvement contributing exercise intensity using feedback from the user as a reward using reinforcement learning. That is, when the user actually exercises after obtaining the optimized target brain function improvement contributing exercise intensity, the following results can be obtained.

[0036] (6) Duration of exercise

[0037] (7) Volatility of exercise intensity that contributes to improving brain function, based on the target exercise intensity that contributes to improving brain function

[0038] (8) (If possible) The user's subjective evaluation of the presented exercise intensity (target brain function improvement contribution exercise intensity) According to such a brain function improvement promotion program, it is possible to easily promote improvement of brain function appropriate for the user.

[0039] The formula for calculating the exercise intensity that contributes to improving the optimized target brain function is not limited to a single method among the rule-based model, machine learning model, and deep learning model described above, but by combining multiple models to make predictions, it is possible to provide a more optimized output for the user.

[0040] Through the above process, the formula for calculating the optimized target brain function improvement contributing exercise intensity, which constitutes the target brain function improvement contributing exercise intensity calculation unit, continues to be learned for each user, either constantly or appropriately. This allows the original purpose of "maximizing the effect of brain function improvement" to be achieved by "setting the highest possible target brain function improvement contributing exercise intensity while satisfying the condition of continuous or uninterrupted exercise" for each user.

[0041] In addition, the learning procedures of the above learning models are all carried out based on the following concept.

[0042] (A) Prepare the i-th input, xi.

[0043] (B) The input is fed to a model F(·;θ) with parameters θ, and the prediction yi = F(xi;θ) for the i-th data point is calculated.

[0044] (C) Calculate the error between the prediction yi and the correct answer yi for the i-th data.

[0045] (D) Update the model parameter θ based on the error.

[0046] (E) Repeat steps (A) through (D) above for all training data until the model training converges on the development data.

[0047] In the brain function improvement promotion device, the brain function improvement contributing exercise intensity may include at least one of oxygen intake, calories burned, number of steps, subjective exertion intensity, and repetition maximum.

[0048] The present inventors focused on the brain function improvement-contributing exercise intensity, which is an exercise intensity that contributes to improving brain function, for exercise of a certain exercise intensity that is effective for suppressing the decline of a user's brain function or improving the user's brain function, including suppressing the progression of dementia or improving dementia. In this regard, it has been found that the extent to which an exercise of a certain exercise intensity that is effective for suppressing the decline of a user's brain function or improving the user's brain function, including suppressing the progression of dementia or improving dementia, actually has a positive effect on a certain person is determined by the certain exercise intensity, exercise time, and frequency of the exercise. This method of expressing exercise intensity is collectively called "brain function improvement-contributing exercise intensity." Brain function improvement-compatible exercise intensity is defined as a method of expressing exercise having an exercise intensity that exerts a brain function or cognitive function improvement effect.

[0049] There are several ways to express "exercise intensity that contributes to improving brain function" as follows:

[0050] When the calorie consumption is used as the expression method, the brain function improvement promotion device or the brain function improvement promotion system measures the actual physical activity and its duration after setting the target calorie value, evaluates the value of the actual calorie consumption based on a predetermined standard, judges whether or not the target has been achieved and the degree to which it has been achieved, and generates the result. The evaluation based on the predetermined standard may be based on a unit of physical activity called METs.

[0051] Oxygen intake is used as an index of aerobic endurance, and one of the index values ​​of the standard exercise intensity is the maximum oxygen intake (VO2max), which is the maximum amount of oxygen that the body can consume during exercise. Specifically, VO2max is the maximum amount of oxygen that can be taken in per minute per kg of body weight. A high VO2max allows the lungs to take in oxygen more effectively and send it to muscles such as the heart, increasing the amount of blood that the heart can send out with one beat. When using VO2max as a method of expression, the brain function improvement promotion device or brain function improvement promotion system measures the value of VO2max and its duration based on actual physical activity, evaluates it based on a predetermined standard, determines whether or not it has been achieved and to what extent, and generates the result. As another standard exercise intensity for oxygen intake, the maximum oxygen intake (VO2peak), which is the highest value of oxygen intake obtained in a specific incremental load protocol, may be used.

[0052] The Rate of Perceived Exertion (RPE) method is a method of expressing the subjective load during exercise in numbers, and is a method of expressing how physically and mentally difficult the activity during exercise is felt by the user based on his / her own sense. Specifically, there are methods such as the Borg scale and the modified Borg scale (category Reoci scale). In the case of the RPE method, since the user needs to express it based on his / her own sense, the user sets the target scale point and its duration, and then inputs the scale point of the actual physical activity that the user will be performing into the brain function improvement promotion device or brain function improvement promotion system, which measures the exercise corresponding to the scale point and its duration, evaluates it based on a predetermined standard, judges whether or not it has been achieved and the degree to which it has been achieved, and generates the result.

[0053] The Repetition Maximum (RM) method is a method of determining exercise intensity based on how many times a joint movement can be repeated with a certain weight. The load that is the limit for X times is represented as XRM. Specifically, the load that is the limit for the first floor is represented as 1RM, and the load that can be repeated up to 5 times is represented as 5RM. High loads of 1RM to 3RM are expected to improve the nervous system and increase muscle strength, while low loads of 12RM or more are expected to increase muscle endurance as well as provide a certain level of aerobic exercise. In the case of the RPE method, since the user needs to express it by his or her own sense, the user sets the target X (X is the number of times the load is repeated, such as 1 or 12), the corresponding weight, and its duration, and then inputs the X of the actual physical activity that the user will be performing and the corresponding weight into the brain function improvement promotion device or brain function improvement promotion system, which measures the exercise and its duration according to the X and weight, evaluates it based on a specified standard, determines whether or not it has been achieved, and generates the results.

[0054] When the number of steps is used as the method of expression, the brain function improvement promotion device or the brain function improvement promotion system may set the number of steps to be a target for a certain day, measure the number of steps on that certain day, evaluate it based on a predetermined standard, judge whether or not the target has been achieved, and generate the result. In addition to simply measuring the number of steps, the average walking speed and average stride length may be taken into consideration to evaluate whether the physical activity corresponding to the number of steps was a high-intensity walk or was evaluated as jogging, and its duration, and the exercise intensity and duration of the physical activity may be set as a goal overall, and then the target may be evaluated based on a predetermined standard to judge whether or not the target has been achieved, and generate the result. Note that the number of steps includes a step number index adjusted by the average walking speed and / or the average stride length.

[0055] The brain function improvement promotion system of the present disclosure is a brain function improvement promotion system that promotes improvement of a user's brain function, and includes a measurement sensor that can be worn on the user's body and includes a brain function improvement contributing exercise intensity measuring unit that measures brain function improvement contributing exercise intensity over time, which is the exercise intensity that contributes to the improvement of the user's brain function, and a terminal device that can communicate with the measurement sensor.

[0063] [Details of the embodiment of the present invention] Next, an embodiment of the brain function improvement and promotion device of the present disclosure will be described with reference to the drawings. In the following drawings, the same or corresponding parts are designated by the same reference characters, and the description thereof will not be repeated.

[0064] (Embodiment 1) The configuration of a brain function improvement promotion device according to the first embodiment of the present disclosure will be described. Fig. 1 is a diagram illustrating a schematic external view of the brain function improvement promotion device according to the first embodiment. Fig. 2 is a block diagram illustrating the configuration of the brain function improvement promotion device illustrated in Fig. 1.

[0065] 1 and 2, the brain function improvement promotion device 11 in the first embodiment is detachable from the user's body. That is, the user can wear the brain function improvement promotion device 11 in the first embodiment on his / her body or detach it. The brain function improvement promotion device 11 is, for example, a wristwatch type, and can be worn by wrapping it around the user's arm. Note that the device may be other than the wristwatch type, for example, a wristband type, a ring type, etc. In addition, these wristwatch type, wristband type, ring type, etc. may be linked to a mask required for direct measurement of oxygen intake, for example. The mask is also, of course, detachable from the user's body.

[0066] The brain function improvement promotion device 11 includes a display screen 12 for displaying data, and a band 13 for wrapping around the user's arm. When the brain function improvement promotion device 11 is wrapped around the user's arm with the band 13, the display screen 12 is disposed in a position visible to the user. In addition, the brain function improvement promotion device 11 has buttons 14 for performing various settings disposed on the side of the display screen 12.

[0067] The brain function improvement promotion device 11 includes a control unit 21 that controls the brain function improvement promotion device 11 itself, a storage memory 22 as a storage unit, an oxygen intake measurement unit 23 as a brain function improvement contribution exercise intensity measurement unit that measures the brain function improvement contribution exercise intensity of the user over time, a communication unit 24 that communicates with the brain function improvement promotion device 11 and the outside, and a time measurement unit 25 that measures time. Since the brain function improvement promotion device 11 has the time measurement unit 25, it also functions as a simple clock. The oxygen intake measurement unit 23 may measure the oxygen intake from a mask that can measure the oxygen intake with which data is linked. Alternatively, the oxygen intake may be estimated and measured using a predetermined calculation formula from the heart rate measured by the brain function improvement promotion device 11 such as a wristwatch type, wristband type, ring type, etc.

[0068] The control unit 21 includes a target oxygen intake amount calculation unit 31 as a target brain function improvement contributing exercise intensity calculation unit, a setting unit 32, a first judgment unit 33, a duration measurement control unit 34, a second judgment unit 35, a memory control unit 36, a display data generation unit 37, and a display control unit 38. The target oxygen intake amount calculation unit 31 calculates a target oxygen intake amount, which is a target brain function improvement contributing exercise intensity set as a target exercise intensity necessary for the user to promote improvement of brain function, and a target time to be reached within a predetermined time limit. The setting unit 32 sets the target oxygen intake amount and the target time calculated by the target oxygen intake amount calculation unit 31. The first judgment unit 33 judges whether the oxygen intake amount of the user measured by the oxygen intake amount measurement unit 23 is equal to or greater than the target oxygen intake amount set by the setting unit 32. If the first judgment unit 33 judges that the oxygen intake amount of the user is equal to or greater than the target oxygen intake amount, the duration measurement control unit 34 controls the time measurement unit 25 to measure a duration time during which the oxygen intake amount is equal to or greater than the target oxygen intake amount. The second determination unit 35 determines whether the total duration measured within a predetermined period of time reaches the target time set by the setting unit 32. If the second determination unit 35 determines that the duration has reached the target time, the memory control unit 36 ​​controls the memory unit to store the fact that the duration has reached the target time. If the second determination unit 35 determines that the total duration has reached the target time, the display data generation unit 37 generates display data for displaying data based on the reaching of the target time on the display screen 12. The display control unit 38 controls the display screen 12 to display at least one of the target oxygen intake amount, actual related data, and time generated by the target oxygen intake amount calculation unit 31, and the display data generated by the display data generation unit 37. These configurations will be described in detail later.

[0069] Next, a case where a target oxygen intake amount, which is a target brain function improvement contributing exercise intensity, is calculated and set will be described. FIG. 3 is a flow chart showing a typical process for calculating and setting a target oxygen intake amount. Referring to FIG. 3, first, a user wears the brain function improvement promotion device 11 on his / her arm. Here, by pressing a switch or the like, the brain function improvement promotion device 11 starts measuring the maximum oxygen intake amount by the oxygen intake amount measuring unit 23 (step S11 in FIG. 3; hereinafter, "step" will be omitted). After a predetermined time has elapsed, the measurement of the maximum oxygen intake amount by the oxygen intake amount measuring unit 23 is terminated (S12). Then, the target oxygen intake amount calculating unit 31 calculates and sets the target oxygen intake amount and the target time (S13).

[0070] Here, an example of the target oxygen intake is as follows. First, the oxygen intake measurement unit 23 measures the maximum oxygen intake, which is the maximum value of the oxygen intake obtained in a predetermined incremental loading protocol. This maximum oxygen intake may be obtained by input from the user. This maximum oxygen intake differs for each user. Then, the value calculated by the following formula becomes the target oxygen intake.

[0071] Target oxygen intake = exercise intensity x maximum oxygen intake Here, the exercise intensity is a numerical value set by the user and is expressed as a percentage, and a value such as 50% or 60% is selected.

[0072] The target time to be reached within a certain time limit is set to, for example, 120 minutes or 150 minutes per week. It is not necessary to achieve the target time in one exercise session, but rather, it is often desirable to achieve the target time in a balanced manner throughout the week. In this case, the duration that reaches the predetermined set time is accumulated over multiple sessions, thereby reaching the target time of 120 minutes or 150 minutes. For this set time, one type of set time of 60 minutes may be prepared as a single set time for the purpose of improving brain function. For example, if exercise is performed twice for more than 60 minutes in a week, the accumulated exercise time is 120 minutes, and the target time of 120 minutes for the week is achieved after satisfying the conditions. For this set time, two types of set times, 30 minutes as a first set time and 5 minutes as a second set time, may be prepared for the purpose of improving brain function. This second set time may be a certain continuous time that is considered to be minimally effective for improving brain function, or may be a minimum value that satisfies the condition of continuous or uninterrupted exercise when displayed to the user. For example, if 30 minutes of exercise (reaching the second set time and the first set time) is performed twice during one week, and 5 minutes of exercise (reaching the second set time but not the first set time) is performed 12 times, the cumulative exercise time is 120 minutes, and the weekly target time of 120 minutes is achieved after satisfying the conditions. The target oxygen intake and target time set as the target exercise intensity may be displayed on a display screen described later. Note that, although 30 minutes is specified as the first set time in the above, this is not limited thereto, and if it is useful for the purpose of improving brain function, the first set time may be specified as a time that is the minimum observable value, such as 1 minute, 1 second, or 0.01 second, as long as it is observable. Also, if a time shorter than the first set time is specified as the second set time, for example, 1 minute is specified as the first set time, the second set time may be specified as a time that is the minimum observable value, such as 30 seconds or 0.01 seconds, as long as it is observable. If it is useful for the purpose of improving brain function, three or more set times may be provided.

[0073] The target oxygen intake calculation unit 31 may calculate an optimized target oxygen intake, which is the highest possible target oxygen intake while satisfying the condition of performing exercise continuously or uninterruptedly, as the target oxygen intake. That is, the target oxygen intake calculation unit 31 may calculate an optimized target oxygen intake, which is the highest possible target oxygen intake while satisfying the condition of performing exercise continuously or uninterruptedly, as the target oxygen intake. This calculation may be performed using at least one of the above-mentioned rule-based model, machine learning model, and deep learning model.

[0074] Thereafter, the target oxygen intake amount and the target time are set by the setting unit 32 .

[0075] Next, the operation of such brain function improvement promotion device 11 in a situation where a target exercise intensity is set will be described. Fig. 4 is a flow chart showing a typical process for promoting improvement of brain function using brain function improvement promotion device 11 in embodiment 1. As the set time, for the purpose of improving brain function, one type of set time may be prepared as a single set time, or two or more types of set times may be prepared. In Fig. 4, two types of set times, a first set time and a second set time, are set.

[0076] With reference to FIG. 4, when the user wears the brain function improvement promotion device 11 on his / her arm, the oxygen intake measurement unit 23 included in the brain function improvement promotion device 11 detects the oxygen intake of the user. Then, the oxygen intake measurement unit 23 measures the oxygen intake of the user over time (S21). That is, the oxygen intake measurement unit 23 starts measuring the oxygen intake of the user over time. In this case, the oxygen intake measurement unit 23 may start measuring the oxygen intake of the user by detecting the pressing of the button 14 provided in the brain function improvement promotion device 11. In addition, the brain function improvement promotion device 11 may include a mechanism for measuring a heart rate, and may measure the heart rate when worn by the user using this mechanism, and may start measuring the oxygen intake by the oxygen intake measurement unit 23 by measuring an estimated value of the oxygen intake based on the heart rate.

[0077] After starting the measurement of the oxygen intake amount, the user goes about his or her daily life while wearing the brain function improvement promotion device 11 on his or her arm. In this case, for example, the user walks a dog, or performs exercises that move the user's body, such as housework or gardening. Note that this normal exercise does not include running or swimming, which the user considers to be aerobic exercise. For example, the user walks a dog and continues walking with the dog for a long time. The first determination unit 33 determines whether the user's oxygen intake amount measured by the oxygen intake amount measurement unit 23 is equal to or greater than the target oxygen intake amount set for each user (S22).

[0078] If the first judgment unit 33 judges that the user's oxygen intake has reached or exceeded the target oxygen intake (YES in S22), the duration measurement control unit 34 controls the time measurement unit 25 to measure the duration during which the oxygen intake is at or above the target oxygen intake (S23).

[0079] Then, the user continues to walk the dog. As a result, the oxygen intake continues to be equal to or greater than the target oxygen intake. Here, the second judgment unit 35 judges whether the measured duration has reached a predetermined second set time (S24). Here, the second set time is defined as a certain continuous time that is considered to be the minimum effective for improving brain function. For example, a value such as 5 minutes (300 seconds) is selected. The second set time is shorter than the first set time described below.

[0080] If the second determination unit 35 determines that the duration has reached the second set time, the measurement of the oxygen intake amount continues thereafter. The user continues walking the dog.

[0081] Then, the second judgment unit 35 judges whether the duration reaches a first set time that is longer than the second set time (S25). The first set time is a period of time that is recognized as a certain exercise that is effective for improving brain function in a series of continuous exercises, and a value such as 30 minutes (1800 seconds) is selected.

[0082] If the second judgment unit 35 judges that the duration has reached the first set time (YES in S25), the second judgment unit 35 judges whether the total duration measured within the specified time limit has reached the target time (S26). In this case, if the second judgment unit 35 judges that the total duration measured within the specified time limit has reached the target time (YES in S26), it controls the storage memory 22 to store the fact that the target time has been reached (S27).

[0083] Thereafter, the display data generating unit 37 generates display data for displaying on the display screen 12 a message indicating that the total duration has reached the target time according to the second determination unit 35 (S28). Then, the display control unit 38 controls the display data generated by the display data generating unit 37 to be displayed on the display screen 12 (S29).

[0084] Fig. 5 is a schematic diagram showing an example of display data displayed on the display screen 12. Referring to Fig. 5, the display screen 12 displays display data 41 of duration, which is the time during which an oxygen intake equal to or greater than the target oxygen intake was measured, display data 42 of oxygen intake, which is the measured oxygen intake (not limited to the oxygen intake at the current time, but may be an average value of the oxygen intake during a certain period including the oxygen intake at the current time), and display data 43 of the word "wonderful" as a compliment for reaching the target time. When the user comes back from walking his dog, he can visually check the display data 41, 42, and 43 visualized on the display screen 12.

[0085] According to the brain function improvement promotion device 11 of the present disclosure, it is possible to easily promote improvement of brain function appropriate for the user.

[0086] If the second judgment unit 35 does not judge that the duration has reached the second set time in S24 (NO in S24), the process returns to S22 to judge whether the measured oxygen intake is equal to or greater than the target oxygen intake. If the second judgment unit 35 does not judge that the duration has reached the first set time in S25 (NO in S25), the memory control unit 36 ​​controls the memory 22 to store the information indicating that the second set time has been reached and the duration data (S30). In this case, the total duration may be displayed. The second judgment unit 35 then judges whether the total duration within a predetermined period has reached the target time (S31). If the target time has not been reached (NO in S31), the process returns to S22 to judge whether the measured oxygen intake is equal to or greater than the target oxygen intake. On the other hand, if the target time has been reached (YES in S31), the memory control unit 36 ​​controls the memory 22 to store the information indicating that the target time has been reached (S27). Thereafter, the display data generating unit 37 generates display data for displaying on the display screen 12 a message indicating that the total duration has reached the target time according to the second determination unit 35 (S28). Then, the display control unit 38 controls the display data generated by the display data generating unit 37 to be displayed on the display screen 12 (S29).

[0087] Furthermore, if the second judgment unit 35 does not judge in S26 that the total duration has reached the target time (NO in S26), the memory control unit 36 ​​controls the memory 22 to store the information indicating that the first set time has been reached and the data on the duration (S32). In this case, the total duration may be displayed. Similarly, the second judgment unit 35 judges whether the total duration for a predetermined period has reached the target time (S31). If it is not judged that the target time has been reached (NO in S31), the process returns to S22 to judge whether the measured oxygen intake is equal to or greater than the target oxygen intake. On the other hand, if it is judged that the target time has been reached (YES in S31), the memory control unit 36 ​​controls the memory 22 to store the information indicating that the target time has been reached (S27). The subsequent processes S28 and S29 are the same as those described above.

[0088] By doing this, even if the duration does not reach the target time, if the first set time is reached, the user can easily visually recognize that fact. Therefore, it is possible to promote the improvement of brain function by trying to continue or uninterruptedly perform a similar constant exercise in daily life so as to approach the target time. The same applies to the second set time.

[0089] In addition, by doing this, even if the duration does not reach the target time, the duration can be added up and displayed, etc., so that it is possible to visually appeal to the user that an effective exercise that leads to improvement of brain function has been performed. Therefore, it is possible to promote the improvement of brain function through exercise within a specified period of time.

[0090] In addition, such a routine is performed every predetermined time period, for example, once a week. For example, the target time is 120 minutes, and the set time is divided into two types, the first set time is 30 minutes, and the second set time is 5 minutes. If the first set time of 30 minutes is conditioned to be achieved at least twice a week, the display screen is prompted to display at least two 30-minute x 2 exercises per week, totaling 120 minutes of exercise. In this case, 30 minutes x 4 = 120 minutes may be used, or 30 minutes x 2 plus 5 minutes x 12 exercises, which is the second set time, may be added to make a total of 120 minutes of exercise. Also, if a 90-minute exercise is performed once beyond the first set time, one first set time, i.e., one 30-minute exercise, may be added within that week to make a total of 120 minutes for the week.

[0091] (Embodiment 2) Next, another embodiment, embodiment 2, will be described. Fig. 6 is a block diagram showing a brain function improvement promotion system according to embodiment 2. The brain function improvement promotion system according to embodiment 2 differs from the brain function improvement promotion device 11 according to embodiment 1 in that the brain function improvement promotion system according to embodiment 2 includes a measurement sensor that measures oxygen intake and a terminal device.

The terminal device 53 includes a terminal device communication unit 61 that communicates with the outside, a terminal device control unit 62 that controls the terminal device 53 itself, a display screen 63, a time measurement unit 64 that measures time, and a terminal device memory 65 as a storage unit that stores data.The terminal device control unit 62 includes a target oxygen intake calculation unit 71 as a target brain function improvement contribution exercise intensity calculation unit that calculates a target oxygen intake set as a target exercise intensity necessary for the user to promote improvement of brain function and a target time to be reached within a predetermined time limit, a setting unit 72 that sets the target oxygen intake and target time calculated by the target oxygen intake calculation unit 71, a first judgment unit 73 that judges whether the oxygen intake of the user measured by the oxygen intake measurement unit 56 has become equal to or greater than the target oxygen intake set by the setting unit 72, and a duration measurement control unit 74 that controls the time measurement unit 64 to measure the duration during which the oxygen intake of the user is equal to or greater than the target oxygen intake if the first judgment unit 73 judges that the oxygen intake of the user has become equal to or greater than the target oxygen intake. a second judgment unit 75 which judges whether the total duration measured within a specified period of time has reached the target time set by the setting unit 72; a memory control unit 76 which, if the second judgment unit 75 judges that the duration has reached the target time, controls the terminal device memory 65 to store information that the duration has reached the target time; a display data generation unit 77 which, if the second judgment unit 75 judges that the total duration has reached the target time, generates display data for displaying data based on the reaching of the target time on the display screen 63; and a display control unit 78 which controls at least one of the target oxygen intake amount, actual related data and time calculated by the target oxygen intake amount calculation unit 71, and the display data generated by the display data generation unit 77 to be displayed on the display screen.

[0093] 7 and 8 are schematic diagrams showing examples of display data displayed on the display screen 63. First, referring to FIG. 7, the display screen 63 displays area data 81a visually showing the degree of exercise achievement as the size of a circle, graph data 82a showing the exercise intensity reached corresponding to the day of the week, and icon data 83a for operation, in addition to various data displays. The user can visually recognize the size of the circle of the area data 81a shown in FIG. 7, in particular, to increase the motivation to work hard at exercise.

The user can visually recognize the smallness of the circle of the area data 81b shown in FIG. 8, in particular, to increase the motivation to work hard at exercise.

[0094] According to such brain function improvement promotion system 51, it is possible to easily promote improvement of brain function appropriate for the user.

[0095] (Other embodiments) In the above embodiment, the display data generating unit may generate display data to display that fact if the first determining unit does not determine that the oxygen intake of the user measured by the oxygen intake measuring unit is equal to or greater than the target oxygen intake within a certain period of time from a predetermined timing measured by the time measuring unit. In this way, it is possible to visually appeal to the user that the user has not performed exercise that would result in an oxygen intake equal to or greater than the target oxygen intake for a certain period of time. Therefore, it is possible to encourage the user to perform aerobic exercise that will result in an oxygen intake equal to or greater than the target oxygen intake in their daily lives.

[0096] In the above embodiment, the determination by the first determination unit may be refreshed at a predetermined timing, which can effectively promote repeated, consistent aerobic exercise over a short period such as one week or a long period such as several months.

[0097] In the above embodiment, the improvement of brain function may include at least one of the following: suppression of the progression of dementia, suppression of brain atrophy, and improvement of brain health score. The above-mentioned certain aerobic exercise is very effective in suppressing the progression of dementia, suppressing brain atrophy, and improving brain health score.

[0098] In the above embodiment, the brain function improvement contributing exercise intensity is mainly described using the oxygen intake, but the brain function improvement contributing exercise intensity may be any one of the above-mentioned calories burned, number of steps, perceived exercise intensity, and repetition maximum. That is, the brain function improvement contributing exercise intensity may be at least one of the oxygen intake, calories burned, number of steps, perceived exercise intensity, and repetition maximum.
