Description

Information providing device, information providing method, and program

[0001] The present invention relates to an information providing device, an information providing method, and a program.

[0002] To prevent lifestyle-related diseases, educational video content that explains the methods and benefits of lifestyle improvement has been proposed (see, for example, Non-Patent Document 1). It is also known that lifestyle improvement is effective when interventions are tailored to the stage of behavioral change (see, for example, Non-Patent Document 2).

[0004] It is believed that more effective interventions can be made by taking into account the motivational factors for the subject to change their behavior, such as the subject's stage of behavioral change and / or interests, but conventional technology has the problem of not being able to selectively provide information that has a high motivational effect.

[0005] An embodiment of the present invention has been made in consideration of the above-mentioned problems, and enables an information provision system that provides content that encourages behavioral change in a target individual to selectively provide content that has a greater motivational effect.

[0006] In order to solve the above problems, an information providing device according to an embodiment of the present invention includes a characteristic information acquisition unit that acquires characteristic information indicating the characteristics of a subject for whom behavioral change is to be encouraged, an element information acquisition unit that acquires element information that is information on motivational elements of multiple motivational contents that encourage the behavioral change, and an information providing unit that provides the subject with a combination of content from the multiple motivational contents that has a higher degree of motivation for the subject based on the characteristic information and the element information.

[0007] According to an embodiment of the present invention, in an information provision system that provides content that encourages a subject to change their behavior, it becomes possible to selectively provide content that has a higher motivational effect.

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0010] <Summary> To prevent lifestyle-related diseases, educational video content that explains the methods and benefits of lifestyle improvement has been proposed (see, for example, Non-Patent Document 1). It is also known that lifestyle improvement is effective when interventions are tailored to the stage of behavioral change (see, for example, Non-Patent Document 2).

[0011] It is believed that more effective interventions can be made by taking into account the motivational factors for the subject to change their behavior, such as the subject's stage of behavior change or interests, but conventional technologies have the problem of not being able to provide effective motivation.

[0012] Therefore, in this embodiment, an information provision system that provides content that encourages a subject to change their behavior is able to selectively provide content that has a high motivational effect. For example, the information provision system personalizes a lecture that the subject is to listen to in order to improve their lifestyle habits.

[0013] <System Configuration> Fig. 1 is a diagram showing an example of the configuration of an information providing system according to this embodiment. In the example of Fig. 1, the information providing system 1 is configured by an information providing device 100.

[0014] (Functional Configuration of Information Providing Device) The information providing device 100 is, for example, an information processing device having a computer configuration, or a system including multiple computers. The information providing device 100 realizes, for example, each functional configuration as shown in FIG. 1 by executing a predetermined program on the computer included in the information providing device 100. In the example of FIG. 1, the information providing device 100 has each functional configuration, such as a characteristic information acquiring unit 101, an intervention determining unit 102, an element information acquiring unit 103, an adding unit 104, a content determining unit 105, an information providing unit 106, and a storage unit 110. Note that at least a portion of each of the above functional configurations may be realized by hardware.

[0015] The characteristic information acquisition unit 101 executes a characteristic information acquisition process to acquire characteristic information indicating the characteristics of a subject for whom behavioral change is to be encouraged. This characteristic information includes, for example, information about the subject's state of behavioral change, personality, and interests. Preferably, the characteristic information includes information about the subject's health checkup results or a health belief model.

[0016] The state of behavioral change includes, for example, five stages of behavioral change: indifference stage, interest stage, preparation stage, action stage, and maintenance stage. The state of behavioral change (stage of behavioral change) is identified based on, for example, responses to a questionnaire given to the subject.

[0017] The indifference stage is when the subject does not believe that behavioral change is necessary. During this stage, interventions such as raising awareness, emotional experiences, or environmental reassessment are effective in helping the subject understand the current situation.

[0018] The interest stage is when the subject believes that behavioral change is necessary. During this stage, interventions such as self-reevaluation are effective in conveying to the subject the specific benefits of behavioral change.

[0019] The preparatory stage is when the subject is thinking about changing their behavior. During this stage, interventions such as self-opening are effective in helping the subject decide for themselves how to act in order to put their change into action.

[0020] The implementation stage is when the subject is taking action to change their behavior, but it has not yet become a habit. The maintenance stage is when they are able to continue taking action to change their behavior. During the implementation and maintenance stages, interventions such as supportive relationships or behavioral substitution are effective in identifying the psychological states and environments that lead to relapse and helping the subject accumulate small successes.

[0021] The results of the health check include, for example, the subject's age, sex, weight, blood type, and / or health condition.

[0022] The health belief model, for example, includes four perceptions: severity, likelihood, threat, benefit, and barrier.

[0023] For the recognition of severity, for example, interventions (encouragement) that make the subject realize what would happen if they were to become ill are considered effective. For the recognition of possibility, for example, interventions that show the subject how likely it is that they will become ill are considered effective. For the recognition of threat, for example, interventions that make the subject feel a sense of crisis are considered effective. For the recognition of benefit, for example, interventions that increase the positive aspects of the subject's behavior are considered effective. For the recognition of disability, interventions that decrease the negative aspects of the subject's behavior are considered effective.

[0024] The characteristic information acquisition unit 101 acquires such characteristic information of the subject and registers the acquired characteristic information in a characteristic information DB (Database) or the like.

[0025] The intervention decision unit 102 executes an intervention decision process to decide an intervention (encouragement) for the subject based on the characteristic information acquired by the characteristic information acquisition unit 101. For example, the intervention decision unit 102 decides an intervention (encouragement) required for the subject based on the state of behavioral change (behavioral change stage) of the subject. Note that the intervention decision unit 102 may decide an intervention required for the subject based on, for example, a health belief model of the subject.

[0026] The characteristic information may include information on an intervention (encouragement) determined in accordance with the state of the subject's behavioral change, instead of the state of the subject's behavioral change. In this case, the information providing device 100 may not include the intervention determination unit 102 (although it may include the intervention determination unit 102).

[0027] The element information acquisition unit 103 acquires element information, which is information on motivation elements of a plurality of motivational content items that encourage behavioral change. The motivational content items according to this embodiment are provided with information (e.g., motivation points) that indicates the state of behavioral change or the degree of motivation for each characteristic information item.

[0028] For example, content that motivates people to improve their lifestyle habits is composed of multiple pieces of content (sessions), such as an explanation of lifestyle-related diseases, an explanation of the benefits of improving lifestyle habits, an explanation of how to improve lifestyle habits, and an introduction of successful cases. In addition, the time required for each piece of content, whether it is a required item or an optional item, and motivational factors for each target person's characteristics are registered as metadata in the content DB 112.

[0029] The element information acquiring unit 103 acquires element information (motivation points), for example, from the content DB 112. Alternatively, the element information acquiring unit 103 may acquire element information from bibliographic information of multiple motivational contents and register the information in the content DB 112. Note that improving lifestyle habits is an example of behavioral change that the subject is encouraged to make.

[0030] The addition unit 104 executes an addition process of adding a weight corresponding to the subject to the element information acquired by the element information acquisition unit 103 .

[0031] Based on their experience in health guidance, medical professionals have their own know-how on effective approaches that are tailored to, for example, the corporate culture or personal characteristics. Therefore, in this embodiment, if a medical professional has a specific request for a particular company or user to listen to, the adding unit 104 can be used to add a weight to the element information. Note that medical professionals include, for example, doctors, public health nurses, registered dietitians, nurses, etc. Note that the information provision system 1 is optional and not required to have the adding unit 104.

[0032] The content determination unit 105 determines a combination of content that will most highly motivate the subject from among the plurality of motivational contents 114, based on the characteristic information acquired by the characteristic information acquisition unit 101 and the element information acquired by the element information acquisition unit 103. The content determination unit 105 may be included in the information provision unit 106. The motivational contents 114 may be stored in the storage unit 110, or may be acquired from an external server, a cloud service, or the like.

[0033] For example, the content determination unit 105 calculates a motivation estimation value S from the characteristic information and the element information, and determines a combination of content with the largest value of S from among multiple motivational contents. For example, the content determination unit 105 sets a threshold value for S and selects a combination of content with a value equal to or greater than the threshold. Alternatively, the content determination unit 105 may select a combination of content with a large S based on the length of the lecture, so that the combination fits within the length of the lecture.

[0034] The content determining unit 105 calculates the motivation estimation value S, for example, by the following formula (1): S = a × Intervention (Stage) + a' × Intervention (Stage (individual weighting)) + b × Interest + c × Personality (1) where a, a', b, and c are weights. Furthermore, "Intervention (Stage)" is, for example, the total value of motivation points corresponding to interventions (interventions) according to the state of the subject's behavioral change. "Intervention (Stage (individual weighting))" is, for example, the total value of motivation points corresponding to individually weighted interventions according to the state of the subject's behavioral change. "Interest" is the total value of motivation points corresponding to the subject's interests. "Personality" is the total value of motivation points corresponding to the subject's personality.

[0035] When not performing individual weighting, the content determining unit 105 may calculate the motivation estimation value S by the following formula (2): S=a×Intervention (Stage)+b×Interest+c×Personality (2), where a, b, and c are weights.

[0036] Furthermore, the content determining unit 105 may completely replace the individual weighting by a medical professional or the like and calculate the estimated motivation value S by the following formula (3): S = a × Intervention (Stage (recommended by medical professional)) + b × Interest + c × Personality (3) where a, b, and c are weights. Furthermore, "Intervention (Stage (recommended by medical professional))" is, for example, the total value of motivation points corresponding to interventions according to the state of behavioral change of the subject, which are individually weighted by a medical professional or the like.

[0037] The information providing unit 106 performs an information providing process of providing the subject with a combination of content that is most motivating to the subject from among a plurality of motivational contents based on the characteristic information and the element information. For example, the information providing unit 106 presents the subject with a combination of content determined by the content determining unit 105 based on the characteristic information acquired by the characteristic information acquiring unit 101 and the element information acquired by the element information acquiring unit 103.

[0038] The storage unit 110 stores, for example, a characteristic information DB 111, a content DB 112, correspondence information 113, and a plurality of motivational contents 114, etc.

[0039] 1 is an example. For example, the storage unit 110 may be provided outside the information providing device 100, or may be provided outside the information providing system 1. The intervention determination unit 102 may be included in the content determination unit 105. The content determination unit 105 may be included in the information providing unit 106. The functional components of the information providing device 100 may be distributed across multiple computers.

[0040] <Processing Flow> Next, the processing flow of the information providing method according to this embodiment will be described.

[0041] 2 is a flowchart showing an example of information provision processing according to the present embodiment. This processing shows an example of information provision processing executed by, for example, the information provision system 1 and the information provision device 100 described with reference to FIG.

[0042] In step S201, the characteristic information acquisition unit 101 acquires characteristic information indicating the characteristics of the subject for whom behavioral change is to be encouraged. This characteristic information includes, for example, information about behavioral change (behavioral change stage), personality, and interests of the subject. Preferably, the characteristic information includes information about the subject's health check results and / or health belief model. The characteristic information acquisition unit 101, for example, registers the acquired characteristic information of the subject in the characteristic information DB 111.

[0043] In step S202, the intervention determination unit 102 determines an intervention (encouragement) according to the state of behavioral change included in the characteristic information acquired by the characteristic information acquisition unit 101. For example, the characteristic information includes the state of behavioral change (stage of behavioral change) identified by the subject's questionnaire responses, etc. The intervention determination unit 102 determines an effective intervention corresponding to the stage of behavioral change using, for example, the correspondence information 113 shown in FIG. 3.

[0044] 3 is a diagram showing an example of correspondence information according to this embodiment. The information providing device 100 stores, for example, correspondence information 113 as shown in FIG. 3 in advance in the storage unit 110 or the like. In the correspondence information 113, "effective interventions" corresponding to "stages" that are states of behavioral change are registered in advance. The intervention determination unit 102 can use this correspondence information 113 to determine effective interventions (encouragement) for the state (stage) of behavioral change of the subject.

[0045] Furthermore, the information providing device 100 executes the processes of steps S203 to S205 in parallel with the processes of steps S201 and S202, for example.

[0046] In step S203, the element information acquisition unit 103 acquires element information that is information on motivation elements of a plurality of motivational contents for encouraging behavioral modification. The information providing device 100 has, for example, a content DB 112 as shown in FIG.

[0047] Fig. 4 is a diagram showing an example of the content DB 112 according to this embodiment. In the example of Fig. 4, the content DB 112 includes information such as ID, content name, time, structure, and motivation element 400 as items.

[0048] The ID is identification information that identifies multiple motivational contents. The content name is information that indicates the name of each content. The time is information that indicates the required time for each content. The configuration is information that indicates whether each content is a required item or an optional item. For example, in Figure 4, the configuration "Selection b(1)" indicates that at least one content must be selected from group b. Furthermore, the configuration "Selection c(0)" indicates that it is not required to select content from group c.

[0049] The motivation elements 400 are information indicating motivation points that indicate the degree of motivation for each motivation element of each content. The motivation elements include, for example, motivation points 401 for each intervention (encouragement) item and motivation points 402 for each characteristic information. The element information acquisition unit 103 acquires the motivation elements 400 as element information from, for example, the content DB 112.

[0050] 2, the adding unit 104 determines whether to add know-how of medical professionals, etc. For example, the adding unit 104 may display a query screen such as "Do you want to assign individual weights?" on a UI (User Interface) screen and determine whether to add know-how of medical professionals, etc. in accordance with an operation on the query screen. Alternatively, the adding unit 104 may determine whether to add know-how of medical professionals, etc. by referring to setting information, etc., preset in the information providing device 100.

[0051] If know-how of medical professionals or the like is to be added, the adding unit 104 shifts the process to step S205. On the other hand, if know-how of medical professionals or the like is not to be added, the adding unit 104 shifts the process to step S206.

[0052] In step S205, the addition unit 104 adds a weighting (individual weighting) to the element information acquired by the element information acquisition unit 103. For example, the addition unit 104 displays a setting screen for weighting the element information on the UI screen, and adds a weighting to the element information in accordance with an operation on the setting screen.

[0053] In step S206, the content determination unit 105 determines, from among the plurality of motivational contents, a combination of contents that will have a higher degree of motivation for the subject, based on the characteristic information acquired by the characteristic information acquisition unit 101 and the element information acquired by the element information acquisition unit 103. For example, the content determination unit 105 calculates the aforementioned motivation estimation value S from the characteristic information and the element information, and determines, from among the plurality of motivational contents, a combination of contents with the largest value of S.

[0054] In step S207, the information providing unit 106 creates content for the target person in accordance with the combination of content determined by the content determining unit 105. For example, the information providing unit 106 acquires the content determined by the content determining unit 105 from the plurality of motivational contents 114 stored in the storage unit 110, and combines the acquired contents to create content to be provided to the target person.

[0055] In step S208, the information providing unit 106 provides the created content to the target person. For example, the information providing unit 106 may display the created content, or may transmit the created content to a terminal device used by the target person and display it.

[0056] By the process of FIG. 2, the information providing system 1 and the information providing device 100 can selectively provide content with a higher motivational effect to a target person for whom behavioral change is to be encouraged.

[0057] <Example> People who are at risk of developing lifestyle-related diseases according to their health checkup results need to improve their lifestyle habits, but the level of interest in lifestyle improvement and the content that motivates them differs from person to person. Here, an example will be explained using a lecture video that is shown at the initial motivation stage for improving lifestyle habits in the health field.

[0058] Example 1 FIG. 5 is a diagram illustrating an example of calculating an S value for user A according to Example 1. In Example 1, user A is a target for encouraging behavioral change. Furthermore, user A's behavioral change state is assumed to be behavioral change stage 1 (indifference), his health check result is hyperglycemia, and his interest is sports. In Example 1, the estimated motivation value S is calculated using formula (2) without adding know-how from medical professionals or the like. S = a × Intervention (Stage) + b × Interest + c × Personality (2) In this case, the interventions (encouragements) required for user A are consciousness enhancement, emotional experience, and environmental reevaluation according to the correspondence information 113 in FIG. 3 . Therefore, the content determining unit 105 calculates the S value by using, for example, the motivation points 501 of "consciousness enhancement," "emotional experience," and "environmental reevaluation" from among the motivation elements in table 500 shown in FIG. 5 as "Intervention (Stage)." Furthermore, since user A is in the indifferent period, the content determining unit 105 increases the weighting of the motivation points 502 for "interest: sports" to arouse user A's interest and make it a personal concern for user A. Furthermore, the content determining unit 105 may increase the weighting of the motivation points 503 for "health check result: hyperglycemia" based on the subject's health check result.

[0059] The content determination unit 105 calculates an S value for each piece of content. Furthermore, as shown in Fig. 5, the content determination unit 105 determines the pieces of content with the highest calculated S values ​​(content IDs D1, D3, and E2). Furthermore, the content determination unit 105 identifies pieces of content that require a certain configuration (content IDs A, B, and F) from the table in Fig. 5.

[0060] As a result, the content determination unit 105 can, for example, combine content that requires a certain structure with content that has a high S value, and determine content 602 that has a high motivational effect on user A from an original performance 601, as shown in Figure 6.

[0061] Example 2 In Example 2, an example of individual weighting will be described using Company B, which has many technical staff and many people for whom theory-based explanations are effective. Medical professionals and others have their own know-how about effective approaches depending on the corporate culture or type of job, based on their past teaching experience.

[0062] In company B, if it is predicted that theory-based explanations will be effective, it may add (or multiply) the weighting of the "Personality: Theoretical" item, as shown in table 700 of FIG. 7. As a result, the motivation point value for the "Personality: Theoretical" item may be doubled, as shown in table 800 of FIG. 8. Alternatively, 2 may be added to the motivation point value for the "Personality: Theoretical" item.

[0063] Furthermore, medical professionals or the like may individually set weighting values ​​to be added for each piece of content, as shown in, for example, table 900 in Fig. 9. Furthermore, as shown in, for example, Fig. 10, medical professionals or the like may set weighting values ​​to be added (or multiplied) using a weighting table 1000 by corporate culture or personality trait, which has been created based on the know-how of medical professionals or the like.

[0064] The information providing device 100 may be capable of subtracting the weighting value by setting a negative value to the individual weighting value.

[0065] In the above-described embodiment, the information providing device 100 has been described as performing an intervention according to the state of behavioral change (stage of behavioral change) using the correspondence information 113 as shown in Fig. 3. However, this is not limited thereto, and the information providing device 100 may perform an intervention according to a health belief model in addition to (or instead of) the intervention according to the state of behavioral change using the correspondence information 1100 as shown in Fig. 11, for example.

[0066] <Hardware Configuration> The information providing device 100 according to this embodiment has, for example, the hardware configuration of a computer 1200 as shown in Fig. 12. Note that the information providing device 100 may be realized by one or more computers 1200. Furthermore, the computer is not limited to a physical machine, and may be, for example, a virtual machine on a cloud.

[0067] Fig. 12 is a diagram showing an example of the hardware configuration of a computer. In the example of Fig. 12, a computer 1200 includes a drive device 1201, an auxiliary storage device 1202, a memory device 1203, a CPU 1204, an interface device 1205, a display device 1206, an input device 1207, and an output device 1208, which are all connected to each other via a bus B. The computer 1200 may further include another processor such as a GPU (Graphics Processing Unit).

[0068] A program for realizing processing in computer 1200 is provided by a recording medium 1211, such as a CD-ROM or a memory card. When recording medium 1211 storing the program is set in drive device 1201, the program is installed from recording medium 1211 to auxiliary storage device 1202 via drive device 1201. However, the program does not necessarily have to be installed from recording medium 1211, but may be downloaded from another computer via a network. Auxiliary storage device 1202 stores the installed program as well as necessary files, data, etc.

[0069] The memory device 1203 reads and stores a program from the auxiliary storage device 1202 when an instruction to start the program is received. The CPU 1204 realizes, for example, functions related to the information providing device 100 in accordance with the program stored in the memory device 1203. The interface device 1205 is used as an interface for connecting to a communication network or the like. The display device 1206 displays a GUI (Graphical User Interface) or the like according to the program. The input device 1207 is composed of a keyboard, a mouse, buttons, and / or a touch panel, and is used to input various operation instructions. The output device 1208 outputs calculation results.

[0070] The CPU 1204 may be another processor such as a DSP (Digital Signal Processor), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array).

[0071] <Effects of the embodiment> According to the present embodiment, in an information provision system that provides content that encourages a subject to change their behavior, it becomes possible to selectively provide content that has a higher motivational effect.

[0072] This means that, for example, in a system that reconstructs and distributes a motivational lecture based on the user's motivational factors, content containing motivational factors appropriate for the user is distributed, thereby encouraging behavioral change.
