Embodiments for Carrying Out the Invention

[0009] Embodiments of the present disclosure will be described with reference to the accompanying drawings. Whenever possible, the same parts are denoted by the same reference numerals, and redundant descriptions are omitted.

[0010] FIG. 1 is a diagram showing the system configuration of the health state estimation system of the present disclosure. As shown in the figure, this health state estimation system includes a terminal log collection device 20, an attribute information acquisition device 50, a position information acquisition device 60, a terminal operation information acquisition device 70, an app usage information acquisition device 80, a healthcare information acquisition device 90, and a health state estimation device 100.

[0011] The terminal log collection device 20 is a device that collects various sensor values and operation log information of the terminal 10 owned by the user.

[0012] The user-reported information management device 30 stores the attribute information for each user. In addition to age, etc., it may also store medical histories including chief complaints, current medical histories, past medical histories, physical findings, examination findings, or mental state information. These pieces of information are information obtained in advance by reporting from the user or the like.

[0013] The attribute information acquisition device 50 is a device that acquires the user's attribute information stored in the user declaration information management device 30 via a network. The user's attribute information indicates at least one of the user's age, gender, family composition, and occupation. Note that information indicating other attributes of the user may also be used. Further, the attribute information may include medical history information including mental state information. For example, information indicating whether the user is in a depressed state or not.

[0014] The location information acquisition device 60 is a device that acquires location information regarding the user's location from the terminal log collection device 20. The location information includes at least one of the latitude and longitude where the user was located or the visited location, information indicating whether the user went out or not, the home stay time when the user stayed at home, the moving distance to the user's destination, the moving time of the user, the moving speed of the user, the means of transportation of the user, the walking distance of the user, the walking time of the user, or the walking speed of the user. These location information are information indicating the user's motor function, information indicating the user's lifestyle, or information indicating the user's sociability.

[0015] The terminal operation information acquisition device 70 is a device that acquires terminal operation information regarding the user's terminal 10 from the terminal log collection device 20. The terminal operation information is information regarding the user's operation of the terminal 10, and includes, for example, at least one of the terminal usage time, the number of times the terminal is used, the number of times the power is turned on / off, the history of changes in various function settings, the number of incoming and outgoing calls, the call time, the remaining battery level, and the time until the battery is restored. These terminal operation information are information indicating the user's cognitive function or information indicating the user's sociability.

[0016] The application usage information acquisition device 80 is a device that acquires usage information of applications (hereinafter abbreviated as applications) operated by a user installed in the terminal 10 from the terminal log collection device 20. The application usage information includes at least one of the application name, the type of application, the setting information in the application, the setting change information of the application, the usage frequency of the application, and the usage time of the application. As types of applications, there are fitness applications (such as pedometers) for promoting exercise for users, medical applications (such as blood pressure monitors, pulse meters, and hair oxygen concentration meters) for managing users' health, map applications for providing map information, route guidance applications, game applications, video viewing applications, camera applications, SNS applications, etc., and they may be distinguished from each other. These application usage information are information indicating exercise functions, cognitive functions, lifestyle habits, or sociality, respectively.

[0017] The healthcare information acquisition device 90 is a device that acquires healthcare information related to the health and exercise of a user detected in the terminal 10 from the terminal log collection device 20. The healthcare information is information including at least one of the user's step count, walking distance, walking speed, calorie consumption, running distance, exercise time or amount of exercise in sports or gym, and BMI. Note that BMI may be acquired as attribute information.

[0018] In addition, although not shown in the figure, there may be a device that acquires the user's behavior history information, conversation voice information, information related to meals, health-related questionnaires, etc. For example, as the behavior history information, there may be a device that acquires the behavior history information of the user for each weekday, holiday or day of the week. This behavior history information is information indicating cognitive functions, lifestyle habits, or sociality. Also, as information related to meals, there may be a device that acquires the number of meals, meal content, and calorie intake. This information related to meals is information indicating oral functions or lifestyle habits. The questionnaire is an answer to a plurality of questions regarding the health status. These information are information pre-registered by the user to be estimated or other users.

[0019] The health state estimation device 100 is a data collection and analysis device that acquires various information acquired by these various acquisition devices and estimates the health state of the user. In the present disclosure, the health state of the user includes not only the physical health state but also the mental health state (cognitive function), and indicates the health state according to aging. This health state according to aging indicates whether the user is frail or pre-frail, and although the physical function and cognitive function are declining, it is a state in which it is possible to prevent the user from becoming in a state requiring care by performing treatment or prevention.

[0020] FIG. 2 is a diagram showing the functional configuration of the health state estimation device 100. As shown in the figure, the health state estimation device 100 includes a data storage unit 101, a health state estimation model generation unit 102, a mental state estimation model generation unit 103, a data acquisition unit 104, a health state estimation unit 105, a contribution data derivation unit 106, and a result notification unit 107.

[0021] The data storage unit 101 is a part that stores learning information for generating the health state estimation model 105a. The learning information includes user information, mental state information, and health state information for each user. The user information is the user's attribute information and behavior information. The mental state information is, for example, information indicating a depressive state. The health state information indicates whether the user is frail or pre-frail. These learning information are information prepared in advance.

[0022] FIG. 3(a) is a diagram showing a specific example of the learning information. As shown in the figure, for each user and the date and time, user information, mental state information, and health state information are stored. The user information is based on the information acquired by each acquisition device as described above. The detailed information thereof is omitted in the figure for convenience of explanation. The mental state information (presence or absence of a depressive state) and the health state information (presence or absence of frailty or pre-frailty) are information obtained based on the declaration by the user. The date and time is the date and time when the user information of the user was acquired.

[0023] This learning information is information prepared in advance by the operator of this system. As shown in Fig. 3(b), some of the user information in the learning information may be missing. For example, in Fig. 3(b), there is no description in the location information of user ID: ccc. In such a case, during the generation process of the prediction model, it may be supplemented based on the information of other users.

[0024] The health state estimation model generation unit 102 is a part that learns the health state estimation model 104a based on the learning information stored in the data storage unit 101. The learning information includes user information, mental state information, and health state information for each user. The health state estimation model generation unit 102 uses the user information and mental state information as inputs (explanatory variables) and the health state information as an output (objective variable) to perform machine learning to learn the health state estimation model. Details will be described later.

[0025] The mental state estimation model generation unit 103 is a part that generates a mental state estimation model 103a for complementing the mental state information of the user. When the health state estimation model generation unit 102 generates a health state estimation model, the mental state information of that user in the learning information may be required but may be missing (see Fig. 3(b)). In that case, a mental state estimation model 103a for complementing the mental state information of that user is generated. The health state estimation model generation unit 102 can obtain the mental state information by inputting the user information into the mental state estimation model 103a.

[0026] The data acquisition unit 104 is a part that acquires user information from each acquisition device such as the attribute information acquisition device 50. The user information includes at least one of attribute information, location information, terminal operation information, application usage information, and healthcare information. Among these information, the location information, terminal operation information, application usage information, and healthcare information are treated as user behavior information.

[0027] The health condition estimation unit 105 is a part that inputs the user information and mental state information of the user to be estimated, which are acquired by the data acquisition unit 104, into the health condition estimation model 105a, and estimates the health condition of the user.

[0028] FIG. 4 is a diagram showing specific examples of user information and mental state information. These user information and mental state information are the information acquired by the data acquisition unit 104 (see FIG. 4(a)). These user information and mental state information of a single user are input into the health condition estimation model 105a, and the health condition information (whether frail or pre-frail) of the single user is output from the health condition estimation model 105a.

[0029] The contribution data derivation unit 106 is a part that derives the data items of which user information data items or mental state information (data items) contributed to the estimation of the user's health condition when predicting the health condition using the health condition estimation model 105a. The contribution data derivation unit 106 uses, for example, known techniques such as Shap and Permutation Importance to derive the data items. These data items are further refined information (coordinate information, usage time information, etc.) of the attribute information, location information, terminal operation information, application usage information, and healthcare information in the user information.

[0030] The result notification unit 107 is a part that notifies the user of the health condition of the user estimated by the health condition estimation unit 105 and the data items derived by the contribution data derivation unit 106. The result notification unit 107 may transmit this information to the terminal 10 owned by the user, or may transmit it to other terminals. Also, when the result notification unit 107 is a display, it may notify the user by displaying.

[0031] This result notification unit 107 may have a function of notifying a message that prompts the health status, the risk of the health status, and the improvement (behavior modification) of the user's behavior. For example, the result notification unit 107 generates and notifies a message that prompts the user to perform an action that improves the health status from the derived data items and the health status described above. As a method for generating the message, data items that contribute to the health status among the data items are extracted using a known algorithm such as shap, and a message that prompts improvement of the data items is generated. The health status includes not only the physical health status but also the mental health status (cognitive function), and indicates the health status according to aging. This health status according to aging indicates whether the user is frail or pre-frail, and although the physical function and cognitive function are declining, it is a state in which the need for care can be prevented by treatment or prevention. The risk of the health status means, for example, the possibility of contracting a disease, the possibility of exacerbation or contracting another disease if already suffering from a disease, and the possibility of being in a health state that increases the risk of contracting a disease even though it is not a disease such as frailty or obesity. A risk estimation model utilizing machine learning may be created and obtained from user information, questionnaires obtained from the user, health examination results, receipt data, and the like.

[0032] The operation of the health status estimation device 100 configured as described above will be described. FIG. 5 is a flowchart showing a method for generating the health status estimation model 105a in the health status estimation device 100 and a method for estimation using the health status estimation model 105a. The health status estimation model generation unit 102 acquires all or part of the user information, mental state information, and health status information as learning information from the data storage unit 101 (S101). The health status estimation model generation unit 102 detects outliers from the user information, mental state information, and health status information, removes them, and also complements the missing values (S102). An outlier is a numerical value that is clearly abnormal and is extremely large or small. For example, it is conceivable that the number of times of using the application is a value that is not normally possible. In such a case, it is supplemented with the average value in consideration of other learning information, but it is not limited to this and may be a predetermined numerical value.

[0033] Then, the health state estimation model generation unit 102 generates a health state estimation model 105a based on the learning information by machine learning (S103).

[0034] The health state estimation unit 105 estimates the user's health state using the generated health state estimation model 105a (S104). The result notification unit 107 notifies the estimated user's health state (S105). Also, the contribution data derivation unit 106 may derive the data items that contributed to the estimation result when estimating the user's health state, and the result notification unit 107 may notify the data items together. Note that in the figure, it is described that the processes S103 and S104 are executed in a series of flows, but of course, it is not limited to this. Once the process S103 ends and when starting the estimation process, the process S104 may be started. Also, these processes S103 and the processes S104 and S105 may be performed by different devices.

[0035] Next, the details of the generation process of the health state estimation model 105a in the process S103 will be described. FIG. 6 is a flowchart showing the detailed operation.

[0036] The health state estimation model generation unit 102 processes some of the data items (such as the age of the attribute information, the coordinate information of the position information, etc.) of the learning information acquired by the data acquisition unit 104 as necessary (S201). For example, the health state estimation model generation unit 102 may calculate whether the user has gone out from the latitude and longitude information included in the position information, the time of staying at home when the user was staying at home, the moving distance to the user's destination, the moving time of the user, the moving speed of the user, the means of movement of the user, the walking distance of the user, the walking time of the user, or the walking speed of the user, etc., and these data may be normalized. Similarly, new data items may be calculated or normalized in the terminal operation information, application usage information, healthcare information, etc.

[0037] The health state estimation model generation unit 102 acquires learning information (user information, mental state information, and health state information) of users of any age or older (S202). For example, it acquires user information, mental state information, and health state information of users aged 65 or older.

[0038] The health state estimation model generation unit 102 further acquires learning information for an arbitrary period from these learning information (S203). Then, the health state estimation model generation unit 102 clusters one or more users of the learning information using the user information (S204). The user information shall be at least any one of the user's behavior information, the user's age or age group, the user's gender, or the user's family composition.

[0039] In addition to these, clustering may also be performed based on the mental state or social activities. In the present disclosure, social activities are defined based on a part of the location information (such as the presence or absence of going out, the time of staying at home, etc.), a part of the terminal operation information (such as the usage time of the terminal, the number of times of using the terminal, etc.), and the application usage information among the user information. For example, it is estimated that users with the same location information and the same terminal operation information are performing the same social activities, and clustering of the users and their learning information is performed based on these information. In addition, social activities may also be defined based on the behavior history, conversation voice, etc.

[0040] For clustering, for example, Support Vector Machine, Kmeans clustering, etc. may be used, or for example, stratification may be used using data such as the user's age, gender, family composition, etc.

[0041] The health state estimation model generation unit 102 performs the complement processing on the learning information of users who do not include the mental state information (S205). This complement processing is performed for each cluster clustered based on the user information.

[0042] The health state estimation model generation unit 102 selects data items that are highly related to the health state (frail or pre-frail) from the learning information subjected to the complementation process using an arbitrary method (known machine learning or feature selection tool) (S207). Note that mental state information is selected as essential. Here, as known machine learning or feature selection tools, Lasso, ElasticNet, Boruta (XGBoost, LightGBM, RandomForest), etc. are known.

[0043] The health state estimation model generation unit 102 applies the selected data items to an arbitrary machine learning method to generate a health state estimation model 105a for the period T1 (S208). For example, as machine learning methods, multiple regression, Lasso, ElasticNet, XGBoost, LightGBM, RandomForest, SVM, Kmeans are known. Note that the selected data items are at least behavior information indicating the user's behavior. For example, in FIG. 3, among the user information, it includes at least one of position information, terminal operation information, application usage information, and healthcare information.

[0044] Here, the complementation process of the mental state information in the process S205 will be described. FIG. 7 is a flowchart showing the detailed process. The health state estimation model generation unit 102 starts a loop process for each cluster clustered in the process S205 (S205a). For example, among the user information, the behavior characteristics of the user change according to the behavior information (position information, terminal operation information, etc.). As a result, the mental state changes, so it is better to complement the mental state information for each user information (especially for each user's behavior information).

[0045] The health state estimation model generation unit 102 applies the learning information of the users including mental state information among the learning information to a known machine learning method to generate a mental state estimation model 103a (S205b). The learning process is performed with the user information as the input (explanatory variable) and the mental state information as the output (objective variable). Note that a part of the user information (the user's behavior information) may be used as the input.

[0046] Then, the health state estimation model generation unit 102 applies the mental state estimation model 103a to the learning information of the user lacking mental state information to estimate the mental state information of the user (S205c). For example, the learning information of the user lacks mental state information (see Fig. 3(b)), and it is estimated whether the mental state information is in a depressive state or not.

[0047] Process S206b and process S206c are performed for each cluster based on the user information (S205d). By this process, the mental state estimation model 103a for each cluster is generated, and the mental state of the user is estimated for each cluster.

[0048] Next, the health state estimation process of process S104 will be described. Fig. 8 is a flowchart showing the health state estimation process. The health state estimation unit 105 processes the data as necessary in each data item of the user information and the mental state information of the user to be estimated acquired by the data acquisition unit 104 (S301). For example, the health state estimation unit 105 may calculate whether the user has gone out from the latitude and longitude information included in the position information, the stay time at home when the user stays at home, the moving distance to the user's moving destination, the moving time of the user, the moving speed of the user, the moving means of the user, the walking distance of the user, the walking time of the user, or the walking speed of the user, etc., and may normalize these data. Similarly, new data items may be calculated or normalized in the terminal operation information, the app usage information, the healthcare information, etc.

[0049] Then, the health state estimation unit 105 extracts the learning information (user information and mental state information) for the period necessary for data complementation (S302).

[0050] The health condition estimation unit 105 complements the data among the data items of the input information that is insufficient for the application of the health condition estimation model 105a based on the extracted learning information (S303). For example, it is complemented with the average value of data of the same gender, the same age range (within a years before and after), and the same BMI (within b before and after). Gender, age, BMI, etc. are calculated based on the attribute information (or healthcare information) in the learning information. When the mental state information is missing, the mental state estimation model 103a generated in FIG. 7 may be used.

[0051] The health condition estimation unit 105 applies the complemented input information to the health condition estimation model 104a to estimate the health condition (S304).

[0052] The result notification unit 107 notifies the estimated health condition (S305).

[0053] Next, the process for notifying the data items that contributed to the estimation will be described. FIG. 9 is a flowchart showing the process. As shown in the figure, processes S301 to S304 are the same as the processes in FIG. 8. The contribution data derivation unit 106 acquires the data items that contributed to the estimation result using the health condition estimation model 104a (S304a).

[0054] Then, the result notification unit 107 notifies the user of the estimated health condition and also notifies information regarding the data items that contributed to the estimation (S305a). The information regarding the data items includes the results for improvement from the health condition. For example, when the contributed data items are among the location information items such as the presence or absence of going out, the staying time at home, and the moving distance, the information regarding the data items is a message prompting to improve it. For example, when it can be determined that the user goes out little and moves little by looking at the location information of the user information, examples of such messages are "Let's go for a walk once a day".

[0055] Next, a modification example of the generation process of the health state estimation model generation unit 102 will be described. FIG. 10 is a flowchart showing the process. Regarding processes S201 to S203, they are the same as those in FIG. 6.

[0056] The health state estimation model generation unit 102 starts a process of looping for each item of age, gender, family composition, mental state, or social activity. That is, the health state estimation model generation unit 102 clusters the learning information for those of the same age, same gender, same family composition, same mental state (presence or absence of depression), or same social activity, and obtains the learning information for each cluster (S211).

[0057] In the present disclosure, social activity is defined based on a part of the location information (presence or absence of going out, home stay time, etc.), a part of the terminal operation information (usage time of the terminal, number of terminal usage times, etc.), and application usage information among the user information. For example, it is estimated that users with the same location information and the same terminal operation information are engaged in the same social activity, and clustering of users and their learning information is performed based on this information. In addition, social activity may be defined based on other behavior history, conversation voice, etc.

[0058] The health state estimation model generation unit 102 extracts data items that are highly related to the health state by any method, such as machine learning or a feature selection tool (S212). This data item shall include a data item related to a specific mental state.

[0059] The health state estimation model generation unit 102 generates the health state estimation model 105a for the period T1 by any machine learning method based on the extracted data items (S213).

[0060] The health state estimation model generation unit 102 repeats these processes in order to generate a health state estimation model for each cluster (S214).

[0061] Next, the operation and effect of the health state estimation device 100 of the present disclosure will be described. The health state estimation device 100 of the present disclosure includes a data acquisition unit 104 that acquires information of a single user (for example, including at least one of position information which is behavior information, terminal operation information, application usage information, healthcare information, and other information other than behavior information) acquired by a terminal 10 held by the single user, a health state estimation model 105a for estimating a health state corresponding to physical and mental aging, and a health state estimation unit 105 that inputs user information into the health state estimation model 105a to estimate the health state of a single user.

[0062] This health state corresponding to physical and mental aging includes at least one of frailty or pre-frailty. Note that the health state may be estimated including the risk of the health state. In the present disclosure, the health state to be estimated may include the risk.

[0063] With this configuration, it is possible to estimate a health state corresponding to physical and mental aging based on the user's information. In the present disclosure, it is particularly estimated that the user is frail or pre-frail.

[0064] Also, in the present disclosure, the health state estimation unit 105 inputs mental state information regarding the mental state into the health state estimation model 105a in addition to the user's information to estimate the health state.

[0065] Health states such as frailty are also greatly affected by the mental state, for example, the depressive state. In the present disclosure, by considering the mental state of the user, an accurate health state can be estimated. Note that in the present disclosure, the depressive state is taken as an example of the mental state, but it may include others, for example, an adjustment disorder including a simple depressive state.

[0066] In the present disclosure, user information includes at least one of information related to motor functions, information related to cognitive functions, information related to lifestyle habits, information related to sociality, and attribute information. In the above description, for the sake of convenience, action information and attribute information are distinguished, but action information may include attribute information. When simply referred to as information in the present disclosure, both are included, but there may also be cases where other information is included.

[0067] In the present disclosure, as an example, information related to motor functions includes at least one or more of the number of steps, step width, number of times of going up and down stairs, speed of going up and down stairs, moving distance, energy consumption, resting energy consumption, exercise time, walking double-support time, and walking asymmetry.

[0068] The number of steps, step width, number of times of going up and down stairs, speed of going up and down stairs, and moving distance are obtained from each sensor value (such as a motion sensor) of the terminal 10. The energy consumption may be calculated based on a predetermined calculation formula based on the above number of steps, etc., or may be calculated by an energy calculation application. The resting energy consumption and exercise time are determined as being in a resting state and an exercise state by each sensor value (such as a motion sensor) of the terminal 10, and the resting energy consumption is obtained by a predetermined mathematical formula or application.

[0069] The walking double-support time is the time when the user stands on both feet based on the walking cycle, and is obtained by a motion sensor or the like of the terminal 10. The walking asymmetry is shown by the detection of an asymmetric step during the walking period. Again, it is obtained by a motion sensor or the like of the terminal 10.

[0070] Also, as an example, information related to cognitive functions includes at least one or more of the time required to unlock the terminal, the time required to use an application after unlocking the terminal, the number of times the terminal is opened, the number of times the terminal is closed, the number of calls, call duration, number of incoming calls, and number of outgoing calls. The time required to unlock the terminal indicates the time from when the user picks up the terminal until it is unlocked. Regarding other parameters as well, they are measured using sensors such as the motion sensor of the terminal 10 and other sensors.

[0071] Also, as an example, the information regarding lifestyle habits includes at least one or more of wake-up time, bedtime, sleep duration, number of times or usage ratio of an app, number of camera shootings, and terminal setting change history.

[0072] For each of these times and the like, the start time and end time are measured using each sensor value (such as a motion sensor) of the terminal 10 and other sensors, and its usage is also measured.

[0073] Also, as an example, the information regarding sociality includes at least one or more of home stay rate, number of location information acquisitions, time away from home, and number of visited destinations.

[0074] These information are based on the location information acquired by the terminal 10. The location information is obtained by GPS, but it is not limited to this.

[0075] Also, as an example, the attribute information includes at least one or more of the user's age or age group or date of birth, the user's gender, the user's family composition, the user's occupation, the user's place of residence, the population density or population density level of the user's place of residence, the user's height, the user's weight, the user's BMI, the user's body type, the user's mental state, or the user's medical history.

[0076] These information are information set by the user in advance. These information are acquired from a user declaration information management device 30 or the like on the network.

[0077] Also, the health state estimation model 105a is a learning model that is clustered into one or more of the user information among the learning information of a plurality of users and is learned based on the user information of the clustered learning information.

[0078] Since the health state changes according to the user's behavior characteristics, the health state estimation model 105a should be prepared according to the behavior characteristics of the user.

[0079] Here, the user information is at least one of the user's behavior information and the user's attribute information. The user's attribute information is at least one of the user's age or age group, the user's gender, the user's family composition, the user's occupation, the user's mental state, or the user's medical history. Also, the user's behavior information may include the user's attribute information.

[0080] Further, in the present disclosure, the health state estimation device 100 includes a data storage unit 101 that functions as a learning information storage unit for storing learning information including information and health state information of a plurality of users, and uses the learning information, with the information as an input and the health state information as an output, to function as a learning unit for learning the health state estimation model 105a by machine learning, and a health state estimation model generation unit 102.

[0081] According to this configuration, the health state estimation model 105a can be generated from the user information and the health state information.

[0082] Further, in the present disclosure, the data storage unit 101 stores learning information further including the mental state information of a plurality of users, and the health state estimation model generation unit 102 generates (learns) the health state estimation model 105a by further adding the mental state information.

[0083] With this configuration, a health state estimation model 105a that takes into account the mental state can be generated. In the health state, especially in cases such as frailty, it is greatly affected by the mental state. Therefore, by generating a health state estimation model 105a that takes into account the mental state, an accurate estimation model can be constructed.

[0084] In addition, in the present disclosure, the health state estimation device 100 uses, as input, the user's information (which may include, for example, behavior information, information other than behavior, attribute information, etc.) among the learning information stored in the data storage unit 101, and outputs the mental state to generate (learn) a mental state estimation model 103a. The mental state estimation model generation unit 103 and the data storage unit 101 further include a complementing unit that inputs the information of a specific user who does not store mental state information into the mental state estimation model 103a, estimates the mental state of the specific user, and complements the learning information. In this case, the health state estimation model generation unit 102 functions as a complementing unit.

[0085] With this configuration, even for learning information lacking mental state information, it can be appropriately complemented.

[0086] In addition, in the present disclosure, in the health state estimation device 100, the health state estimation model generation unit 102 extracts the learning information of users of a predetermined age from the learning information of a plurality of users, and generates a health state estimation model 105a based on the extracted learning information.

[0087] Since health states such as frailty occur based on aging, it is preferable to use learning information according to age.

[0088] As described above, these learning processes do not necessarily have to be performed by the health state estimation device 100, and the health state estimation device 100 may use a learning model generated by another learning model generation device.
