The response information 500 is, for example, information received from the electronic device 100 via the communication unit 230. The response information 500 is associated with, for example, information that can identify the user U, the electronic device 100, and the like.

The control unit 250 is an arithmetic processing device. Arithmetic processing devices include, but are not limited to, for example, CPUs, SoCs, MCUs, FPGAs, and coprocessors. The control unit 250 can comprehensively control the operation of the server 200 and realize various functions.

Specifically, the control unit 250 can execute an instruction included in the program 241 stored in the storage unit 240 while referring to the information stored in the storage unit 240 as necessary. Then, the control unit 250 can control the function unit according to the data and the instruction, thereby realizing various functions. The functional unit includes, but is not limited to, the display unit 210 and the communication unit 230, for example.

The control unit 250 has functional units such as a discrimination unit 251, a determination unit 252, a question unit 253, a counting unit 254, and an output control unit 255. The control unit 250 realizes functions such as a discrimination unit 251, a determination unit 252, a question unit 253, a counting unit 254, and an output control unit 255 by executing the program 241. The program 241 is a program for making the control unit 250 of the server 200 function as a discrimination unit 251, a determination unit 252, a question unit 253, a counting unit 254, and an output control unit 255.

The determination unit 251 determines whether the answer to the question obtained from the user U is the first type of answer or the second type of answer. The determination unit 251 determines whether the answer is the first type of answer or the second type of answer, based on, for example, the response information of the user U acquired via the electronic device 100. The first type of answer includes, for example, change talk. The change talk includes all statements in favor of the changes expressed by User U himself. The second type of answer includes, for example, maintenance talk. The maintenance talk includes, for example, all of the status quo statements against change.

FIG. 8 is a diagram for explaining an example of the change talk and the maintenance talk according to the embodiment. As shown in FIG. 8, the change talk includes, for example, a preparatory change talk and an execution change talk. The preparatory change talk includes, for example, the remark of the user U, which is unlikely to cause behavior change but causes the execution change talk. Execution change talk includes, for example, a statement that is a sign of actual execution.

The preparatory change talk includes, for example, classification of desires, abilities, reasons, needs, and the like. Wishes include, for example, change talks such as wanting to lose weight. On the other hand, the maintenance talk for the change talk of desire includes, for example, remarks such as not wanting to exercise. Abilities include change talks, such as being able to walk. On the other hand, the maintenance talk for the ability change talk includes, for example, remarks such as being healthy without exercising. Reasons include, for example, change talk such as losing weight by exercising. On the other hand, the maintenance talk for the change talk of the reason includes remarks such as, for example, that there is no time to exercise. Needs include, for example, change talks such as being idempotent by summer. On the other hand, the maintenance talk for the change talk of needs includes remarks such as the need for rest rather than exercise.

Execution change talks include, for example, classifications such as commitment, activation, and step-by-step. Commitments include change talks, such as exercising from tomorrow. Maintenance talks for commitment change talks include, for example, remarks such as quitting a diet. Activation includes, for example, change talks such as being willing to go on a diet. The maintenance talk for the activation change talk includes, for example, remarks such as not being willing to exercise. Stepping includes change talk, such as buying shoes for exercise. Maintenance talks for step-by-step change talks include, for example, remarks such as resting exercise.

Change talk and maintenance talk are usually mixed. The probability of behavior change increases when the number of remarks in change talk exceeds the number of remarks in maintenance talk. Therefore, in this disclosure, by strengthening the change talk, the number of remarks of the change talk is increased more than that of the maintenance talk. In the present disclosure, it is possible to increase the execution change talk from the preparation change talk. For example, the second conversation information 320 having directivity sets an answer corresponding to each of the preparation change talk, the execution change talk, and the maintenance talk as the answer item D2. As a result, the discrimination unit 251 can discriminate in detail the answer to the question acquired from the user U.

Returning to FIG. 7, the discrimination unit 251 determines whether the answer of the user U is a change talk or a maintenance talk. The determination unit 251 refers to, for example, a database of change talk and maintenance talk, and determines whether the answer is change talk or maintenance talk. The discrimination unit 251 may be configured to discriminate the answers by using, for example, a trained program in which the teacher data of the change talk answer and the maintenance talk answer are machine-learned. The discrimination unit 251 stores the discrimination result in the storage unit 240.

The determination unit 252 determines whether to maintain the phase of the user currently in the first phase in the first phase or to shift to the second phase based on the determination result by the determination unit 251. Maintaining the first phase means, for example, not shifting from the current phase to another phase. Moving to the second phase means, for example, moving from the current phase to the next or previous phase. The determination unit 252 determines to move to the second phase when the discrimination result of the discrimination unit 251 is the answer of the first type, and when the discrimination result of the discrimination unit 251 is the answer of the second type. , Determine to maintain the first phase.

The determination unit 252 determines whether to maintain the phase of the user U in the first phase or shift to the second phase based on the determination result of the determination unit 251 in the predetermined period. The predetermined period includes an arbitrary period such as, for example, one week or three days. The determination unit 252 maintains the phase of the user U in the first phase based on the ratio of the number of the first type of answers and the number of the second type of answers in the answers obtained from the user U. Decide whether to do so or move to the second phase. When the number of conversations with the user U exceeds the threshold value, the determination unit 252 determines the number of answers of the first type and the number of answers of the second type in the answer, based on the ratio of the user. It is determined whether the phase U is maintained in the first phase or moved to the second phase. The determination unit 252 determines whether to maintain the phase of the user U in the first phase or shift to the second phase based on the number or ratio of the execution change talks acquired from the user U.

The question unit 253 presents the user U a question regarding the task. The question unit 253 presents the question by transmitting the information of the question set in the question item D1 described above to the electronic device 100 and outputting the information to the electronic device 100. The question unit 253 presents a question corresponding to the current phase and for obtaining an answer from the user U.

The decision unit 252 maintains the user U's phase in the first phase or shifts to the second phase based on whether the answer to the question by the question unit 253 is the second type of answer. To decide. The decision unit 252 decides whether to keep the user's phase in the first phase or move to the second phase based on the number of positive answers to the question. When the number of positive answers to the question is the number in which the behavior change of the user U in the phase is established, the determination unit 252 shifts the phase of the user U to the second phase. As the number in which the behavior change of the user U in the phase is established, for example, an arbitrary number can be set as an experimental result.

The counting unit 254 counts the number of times the confirmation conversation continues with the user U. The confirmation conversation includes, for example, a conversation for determining whether or not the user U is a conversation. The counting unit 254 counts, for example, the number of times the confirmation conversation in Phase 1 and the user U's response to the confirmation conversation. For example, in Phase 1, when a predetermined number of responses to the confirmation dialogue are obtained, the server 200 can determine that the conversation is established. The predetermined number of times includes, for example, an arbitrary number of times such as 5 times and 10 times. The counting unit 254 stores the counted result in the storage unit 240.

When the counting result of the counting unit 254 satisfies the determination condition, the determination unit 252 executes a process of determining whether to maintain the phase of the user U in the first phase or to shift to the second phase. The determination condition includes, for example, a condition of 10 or more answers in Phase 1.

The output control unit 255 causes the electronic device 100 that can be operated by the user U to output conversation information for outputting the conversation corresponding to the phase. The electronic device 100 that can be operated by the user U includes, for example, an electronic device 100 owned by the user U, an electronic device 100 that the user U can log in to, and the like. The output control unit 255 instructs the electronic device 100 to output the conversation information via the communication unit 230, so that the electronic device 100 outputs the conversation information.

The output control unit 255 causes the electronic device 100 of the user U to output the first conversation information 310 and then outputs the second conversation information 320. The output control unit 255 causes the electronic device 100 of the user U to output the first conversation information 310, then output the second conversation information 320, output the second conversation information 320, and then different first conversation information. Is output. That is, the output control unit 255 can realize a dialogue with the user U in a scenario conversation in which a chat, a directional conversation, and a chat are set as one set.

When the output control unit 255 outputs the first conversation information 310 at the time of the previous login of the user U, the output control unit 255 does not output the first conversation information 310 to the electronic device 100 based on the log information 330 at the time of the current login. The first conversation information 310 or the second conversation information 320 is output to the electronic device 100. For example, the user U may log in to the same time segment again after the conversation in the time segment ends. In this case, since the output control unit 255 can avoid outputting the same conversation information, it is possible to suppress the user U from feeling annoyed by the conversation.

The output control unit 255 selects the first conversation information 310 and the second conversation information 320 based on the time division of the current time. When the current time is the night of the time division, the output control unit 255 selects the first conversation information 310 that draws out the impression of the day from the user U. The first conversation information 310 that draws out the impression of the day is, for example, conversation information including a conversation that asks the impression of the day. When the second conversation (directional conversation) to the user U has been completed by the planned number, the output control unit 255 causes the electronic device 100 to output the first conversation indicating that the user U is waiting for a predetermined time. The number of schedules can be arbitrarily set for each of a plurality of phases, for example. The output control unit 255 causes the electronic device 100 to output the first conversation information 310, which is not output by the electronic device 100 of the user U, among the plurality of first conversation information 310s. The output control unit 255 extracts the first conversation information 310 that has not been output from the storage unit 240 based on the log information 330, and causes the electronic device 100 to output the first conversation information 310.

As described above, the server 200 described above has a first conversation information 310 indicating a first conversation having at least one directivity and a second conversation information 320 indicating a second conversation having at least one directivity. Can be stored in the storage unit 240. The server 200 can cause the electronic device 100 of the user U to output the first conversation information 310 and then output the second conversation information 320. As a result, the server 200 can realize a conversation with the user U by combining a conversation having no directivity and a conversation having the directivity, so that the personal information of the user U can be used in a natural conversation. I can hear it.

The server 200 causes the electronic device 100 of the user U to output the first conversation information 310, then outputs the second conversation information 320, outputs the second conversation information 320, and then outputs different first conversation information 310. It can be output. As a result, the server 200 can alleviate the feeling of caution by sandwiching the conversation having directivity between the conversations having no directivity, so that the personal information of the user U can be relaxed. Can be heard in a natural conversation.

The server 200 has a question item D1 including a question content for the user U, an answer item D2 including a plurality of answers selected by the user U, and a response item D3 including a response to the answer selected by the user U. The 1 conversation information 310 and the 2nd conversation information 320 can be output to the electronic device 100. As a result, the server 200 can ask the user U to select the answer, so that the user's information can be heard as the answer.

The server 200 can store the log information 330 indicating at least one of the first conversation information 310 and the second conversation information 320 output to the electronic device 100 in the storage unit 240. When the server 200 outputs the first conversation information 310 at the time of the previous login of the user U, the first conversation information 310 is not output to the electronic device 100 at the time of the current login based on the log information 330. The conversation information 310 or the second conversation information 320 can be output to the electronic device. As a result, the server 200 can prevent the user U from getting tired of the dialogue with the server 200 by not outputting the same conversation information to the electronic device 100, so that the personal information of the user U can be heard in a natural conversation. You can get an opportunity.

The server 200 can select the first conversation information 310 and the second conversation information 320 based on the time division of the current time. As a result, the server 200 can give the user U a sense of familiarity by outputting the first conversation information 310 and the second conversation information 320 according to the time division to the electronic device 100, and information about the user U. Can be improved in the possibility of hearing.

When the current time is the night of the time division, the server 200 can select the first conversation information 310 that elicits the impression of the day from the user U. As a result, the server 200 can hear the information of the user U in one day by having the electronic device 100 output the first conversation information 310 that draws out the impression of the day when the time division becomes night.

When the planned number of second conversations with the user U have been completed, the server 200 can have the electronic device output the first conversation indicating that the user U has waited for a predetermined time. As a result, when the number of conversations with the user U reaches the planned number, the server 200 causes the electronic device 100 to output the conversations connected with the user U, and does not forcibly retrieve the personal information of the user U. , It is possible to suppress a decrease in the relationship with the user U.

The server 200 can cause the electronic device 100 to output first conversation information 310 including, for example, at least one of conversations related to greetings, news, weather, quizzes, and play. As a result, the server 200 can give the user U a sense of intimacy by realizing a chat with the user U, and thus can improve the possibility of asking for information about the user U.

As a result, the server 200 can give the user U a sense of intimacy by realizing various conversations with the user, and thus can improve the possibility of asking for information about the user U.

FIG. 13 is a flowchart showing an example of the transition control of Phase 1 executed by the server 200 according to the embodiment. The processing procedure shown in FIG. 13 is realized by the control unit 250 of the server 200 executing the program 241 when the phase of the user U is the phase 1. The processing procedure shown in FIG. 13 is executed by the control unit 250 every time a predetermined period elapses from the start of the conversation with the user U, for example.

As shown in FIG. 13, the control unit 250 collects the information generated in the phase 1 (step S1101). For example, the control unit 250 collects various information indicating the question to the user U, the answer of the user U, and the like performed in the phase 1 from the log information 330, the answer information 500, and the like stored in the storage unit 240. When the process of step S1101 is completed, the control unit 250 advances the process to step S1102.

The control unit 250 counts the number of confirmation conversations in phase 1 (step S1102). For example, the control unit 250 counts the number of times the confirmation conversation continues in Phase 1 based on the number of combinations of the collected questions and answers. When the process of step S1102 is completed, the control unit 250 advances the process to step S1103.

The control unit 250 determines whether or not the confirmation conversation is a predetermined number of times or more (step S1103). For example, when the number of times counted in step S1102 is the predetermined number of times or more, the control unit 250 determines that the confirmation conversation is the predetermined number of times or more. In the example shown in FIG. 13, the predetermined number of times is 10. When the control unit 250 determines that the confirmation conversation is a predetermined number of times or more (Yes in step S1103), the conversation with the user U is established, so the process proceeds to step S1104.

The control unit 250 shifts from Phase 1 to Phase 2 (step S1104). For example, the control unit 250 shifts (changes) the user's phase from phase 1 to phase 2, and reflects the shift to phase 2 in the log information 330. The control unit 250 may perform a process of notifying the user U that the phase 2 has been started. When the process of step S1104 is completed, the control unit 250 ends the process procedure shown in FIG.

Further, when the control unit 250 determines that the confirmation conversation is not more than a predetermined number of times (No in step S1103), the conversation with the user U is not established, so that the process shown in FIG. 13 is performed without shifting to the phase 2. End the procedure.

As described above, the control unit 250 can automatically shift from the phase 1 related to the user to the phase 2 for drawing out the feelings to be improved from the user U by executing the processing procedure shown in FIG.

FIG. 14 is a flowchart showing an example of the transition control of Phase 2 executed by the server 200 according to the embodiment. The processing procedure shown in FIG. 14 is realized by the control unit 250 of the server 200 executing the program 241 when the phase of the user U is the phase 2. The processing procedure shown in FIG. 14 is executed by the control unit 250 every time a predetermined period elapses from the start of the conversation with the user U, for example.

As shown in FIG. 14, the control unit 250 collects the information generated in the phase 2 (step S1201). For example, the control unit 250 collects various information indicating the question to the user U, the answer of the user U, and the like performed in the phase 2 from the log information 330, the answer information 500, and the like stored in the storage unit 240. When the process of step S1201 is completed, the control unit 250 advances the process to step S1202. Here, in the present disclosure, after step S1201, a confirmation operation of the number of conversations may be added as in step S1102 of FIG. In this case, the control unit 250 may count the number of confirmation conversations such as directional conversations in Phase 2. For example, the control unit 250 may count the number of times the confirmation conversation continues in Phase 2 based on the number of combinations of the collected questions and answers. When this process is completed, the control unit 250 may proceed to step S1202.

The control unit 250 determines the answer in Phase 2 (step S1202). For example, the control unit 250 compares the answer of the user U whose main theme is weight with the change talk and maintenance talk of the database, and based on the comparison result, whether the answer is a change talk or a maintenance talk. To determine. For example, the control unit 250 may determine the answer by using a trained program in which the teacher data of the change talk answer and the maintenance talk answer are machine-learned. When the control unit 250 determines that the answer is a change talk, the control unit 250 further determines whether the answer is a preparation change talk or an execution change talk, and determines the classification of the change talk. The control unit 250 determines the classification of the change talk by using the database of the preparation change talk and the execution change talk shown in FIG. The control unit 250 stores the determination result of the answer in the storage unit 240 in association with the response information 500. When the process of step S1202 is completed, the control unit 250 advances the process to step S1203.

The control unit 250 determines whether or not the preparation change talk is larger than the maintenance talk based on the determination result in step S1202 (step S1203). For example, the control unit 250 determines that the number of preparation change talks is larger than the number of maintenance talks when the number of preparation change talks in the phase 2 is larger than the number of maintenance talks. When the control unit 250 determines that the preparation change talk is larger than the maintenance talk (Yes in step S1203), it is highly possible that the problem of the user U can be drawn out, so the process proceeds to step S1204. Here, in the present disclosure, after the control unit 250 determines Yes in step S1203, a process of asking an important question related to the phase transition, such as "Do you consider the problem important?", May be added. In this case, when the control unit 250 receives the answer that the problem is important (Yes), the process proceeds to step S1204, and the answer that the problem is not important (No) is obtained. In that case, the process may be terminated or the process may be advanced to step S1201. Further, in this case, as a process before ending the process or proceeding to step S1201, the control unit 250 performs a process of changing the intervention point for the user as in step S1206 described later, and after this change process, performs a process. You may proceed to step S1201. In this case, the present disclosure can prevent Phase 2 from being repeated with the same intervention theme.

The control unit 250 shifts from Phase 2 to Phase 3 (step S1204). For example, the control unit 250 shifts (changes) the user's phase from phase 2 to phase 3, and reflects the shift to phase 3 in the log information 330. The control unit 250 may perform a process of notifying the user U that the phase 3 has been started. When the process of step S1204 is completed, the control unit 250 ends the process procedure shown in FIG.

Further, when the control unit 250 determines that the preparation change talk is not more than the maintenance talk (No in step S1203), it is highly possible that the problem of the user U has not been drawn out, so the process proceeds to step S1205. The control unit 250 determines whether or not the state in which the preparation change talk is not more than the maintenance talk is continuous for the determination period (step S1205). The determination period can be arbitrarily set, for example, a period of 3 weeks, 1 month, or the like. The determination period may be, for example, the same as the predetermined period or may be longer than the predetermined period. When the control unit 250 determines that the determination period is not continuous (No in step S1205), the control unit 250 ends the processing procedure shown in FIG. In the present disclosure, the processing procedure shown in FIG. 14 may be an operation in which the processing in step S1205 is omitted. That is, if the determination in step S1203 is No, the processing procedure may shift from step S1203 to step S1206.

If the control unit 250 determines that the determination period is continuous (Yes in step S1205), the control unit 250 advances the process to step S1206. The control unit 250 changes the intervention point for the user U (step S1206). For example, the control unit 250 changes the intervention point for the user U from the main theme to the sub-theme, and continues Phase 2 based on the sub-theme. For example, if the main theme is a weight task, the control unit 250 changes to a sub-theme indicating promotion of exercise. When the process of step S1206 is completed, the control unit 250 ends the process procedure shown in FIG.

As described above, the control unit 250 automatically shifts from the phase 2 in which the user U draws out the feelings he / she wants to improve to the phase 3 in which the user U can take action by executing the processing procedure shown in FIG. Can be migrated.

FIG. 15 is a flowchart showing an example of the transition control of the phase 3 executed by the server 200 according to the embodiment. The processing procedure shown in FIG. 15 is realized by the control unit 250 of the server 200 executing the program 241 when the phase of the user U is the phase 3.

As shown in FIG. 15, the control unit 250 collects the information generated in the phase 3 (step S1301). For example, the control unit 250 collects various information indicating the question to the user U, the answer of the user U, and the like performed in the phase 3 from the log information 330, the answer information 500, and the like stored in the storage unit 240. When the process of step S1301 is completed, the control unit 250 advances the process to step S1302. Here, in the present disclosure, after step S1301, a confirmation operation of the number of conversations may be added as in step S1102 of FIG. In this case, the control unit 250 may count the number of confirmation conversations such as directional conversations in Phase 3. For example, the control unit 250 may count the number of times the confirmation conversation continues in Phase 3 based on the number of combinations of the collected questions and answers. When this process is completed, the control unit 250 may proceed to step S1302.

The control unit 250 determines the answer in the phase 3 (step S1302). For example, the control unit 250 compares the answer of the user U whose main theme is weight with the change talk and maintenance talk of the database, and based on the comparison result, whether the answer is a change talk or a maintenance talk. To determine. For example, the control unit 250 may determine the answer by using a trained program in which the teacher data of the change talk answer and the maintenance talk answer are machine-learned. When the control unit 250 determines that the answer is a change talk, the control unit 250 further determines whether the answer is a preparation change talk or an execution change talk, and determines the classification of the change talk. The control unit 250 determines the classification of the change talk by using the database of the preparation change talk and the execution change talk shown in FIG. The control unit 250 stores the determination result of the answer in the storage unit 240 in association with the response information 500. When the process of step S1302 is completed, the control unit 250 advances the process to step S1303.

The control unit 250 determines whether or not the preparation change talk is larger than the maintenance talk based on the determination result in step S1302 (step S1303). For example, the control unit 250 determines that the number of preparation change talks is larger than the number of maintenance talks when the number of preparation change talks in the phase 3 is larger than the number of maintenance talks. When the control unit 250 determines that the preparation change talk is larger than the maintenance talk (Yes in step S1303), the control unit 250 advances the process to step S1304.

The control unit 250 determines whether or not the commitment is greater than the maintenance talk based on the determination result in step S1302 (step S1304). For example, the control unit 250 determines that the commitment is greater than the maintenance talk when the classification is greater than the number of execution change talks of the commitment than the number of maintenance talks. When the control unit 250 determines that the commitment is greater than the maintenance talk (Yes in step S1304), the control unit 250 can draw the intention of the commitment to the task from the user U, so the process proceeds to step S1305. Here, in the present disclosure, as a process after determining Yes in step S1304, a process for asking an important question related to the phase transition, such as "Are you confident in completing the behavior change?", May be added. In this case, the control unit 250 proceeds to step S1305 when the answer is confident (Yes), and ends the process when the answer is not confident (No). Alternatively, the process may proceed to step S1301.

The control unit 250 shifts from Phase 3 to Phase 4 (step S1305). For example, the control unit 250 shifts (changes) the user's phase from phase 3 to phase 4, and reflects the shift to phase 4 in the log information 330. The control unit 250 may perform a process of notifying the user U that the phase 4 has been started. When the process of step S1305 is completed, the control unit 250 ends the process procedure shown in FIG.

Further, when the control unit 250 determines that the commitment is not more than the maintenance talk (No in step S1304), it is highly possible that the user U has not triggered the action, so the control unit 250 does not move to the phase 4. , The processing procedure shown in FIG. 15 is terminated.

Further, when the control unit 250 determines that the preparation change talk is not more than the maintenance talk (No in step S1303), there is a high possibility that the user U has not triggered the action, so the process is set to step S1306. Proceed. The control unit 250 determines whether or not the state in which the preparation change talk is not more than the maintenance talk is continuous for the determination period (step S1306). When it is determined that the determination period is not continuous (No in step S1306), the control unit 250 ends the processing procedure shown in FIG. In this disclosure, the operation of step S1306 may be omitted. That is, if the determination in step S1303 is No, the processing procedure may shift from step S1303 to step S1307.

If the control unit 250 determines that the determination period is continuous (Yes in step S1306), the control unit 250 determines that it is not the timing of intervention, and proceeds to step S1307. The control unit 250 shifts from Phase 3 to Phase 2 (step S1307). For example, the control unit 250 shifts (changes) the phase of the user U from the phase 3 to the phase 2, and reflects the shift to the phase 2 in the log information 330. The control unit 250 may perform a process of notifying the user U that the phase 2 has been started. When the process of step S1307 is completed, the control unit 250 ends the process procedure shown in FIG.

As described above, the control unit 250 executes the processing procedure shown in FIG. 15 to give the user U a feeling that the behavior has been changed from the phase 3 showing the opportunity for the user U to take action. Can be automatically migrated to. Further, when the control unit 250 determines that it is not the timing of the intervention based on the response of the user U in the phase 3, the control unit 250 can automatically return from the phase 3 to the phase 2.

FIG. 16 is a flowchart showing an example of the transition control of the phase 4 executed by the server 200 according to the embodiment. The processing procedure shown in FIG. 16 is realized by the control unit 250 of the server 200 executing the program 241 when the phase of the user U is the phase 4. The processing procedure shown in FIG. 16 is executed by the control unit 250 every time a predetermined period elapses from the start of the conversation with the user U, for example.

As shown in FIG. 16, the control unit 250 collects the information generated in the phase 4 (step S1401). For example, the control unit 250 collects various information indicating the question to the user U, the answer of the user U, and the like performed in the phase 4 from the log information 330, the answer information 500, and the like stored in the storage unit 240. When the process of step S1401 is completed, the control unit 250 advances the process to step S1402.

The control unit 250 determines the answer in the phase 4 (step S1402). For example, the control unit 250 compares the answer of the user U whose main theme is weight with the change talk and maintenance talk of the database, and based on the comparison result, whether the answer is a change talk or a maintenance talk. To determine. For example, the control unit 250 may determine the answer by using a trained program in which the teacher data of the change talk answer and the maintenance talk answer are machine-learned. When the control unit 250 determines that the answer is a change talk, the control unit 250 further determines whether the answer is a preparation change talk or an execution change talk, and determines the classification of the change talk. The control unit 250 determines the classification of the change talk by using the database of the preparation change talk and the execution change talk shown in FIG. The control unit 250 stores the determination result of the answer in the storage unit 240 in association with the response information 500. When the process of step S1402 is completed, the control unit 250 advances the process to step S1403.

The control unit 250 determines whether or not the preparation change talk is larger than the maintenance talk based on the determination result in step S1402 (step S1403). For example, the control unit 250 determines that the number of preparation change talks is larger than the number of maintenance talks when the number of preparation change talks in the phase 3 is larger than the number of maintenance talks. When the control unit 250 determines that the preparation change talk is larger than the maintenance talk (Yes in step S1403), the control unit 250 advances the process to step S1404.

Based on the determination result of step S1402, the control unit 250 determines whether or not there are more steps than the maintenance talk (step S1404). For example, the control unit 250 determines that if the number of execution change talks in which the classification is stepped is larger than the number of maintenance talks, the number of stepped steps is greater than the number of maintenance talks. When the control unit 250 determines that the number of steps is not more than the maintenance talk (No in step S1404), the control unit 250 ends the processing procedure shown in FIG. 16 without shifting from the phase 4 to another phase.

Further, when the control unit 250 determines that there are more steps than the maintenance talk (Yes in step S1404), the control unit 250 advances the process to step S1405. The control unit 250 determines whether or not the state in which the number of steps is taken but is greater than the maintenance talk is continuous for the determination period (step S1405). When it is determined that the determination period is not continuous (No in step S1405), the control unit 250 ends the processing procedure shown in FIG. 16 without shifting from the phase 4 to another phase. If the control unit 250 determines that the determination period is continuous (Yes in step S1405), the control unit 250 advances the process to step S1406.

The control unit 250 shifts from Phase 4 to Phase 5 (step S1406). For example, the control unit 250 shifts (changes) the user's phase from phase 4 to phase 5, and reflects the shift to phase 5 in the log information 330. The control unit 250 may perform a process of notifying the user U that the phase 5 has been started. When the process of step S1406 is completed, the control unit 250 advances the process to step S1407.

The control unit 250 starts a process of supporting the maintenance of behavior change (step S1407). The process of supporting the maintenance of the behavior change includes, for example, a process of inducing the user U to the content for maintaining the behavior change, a process of recommending an appropriate article or service to the user U, and the like. When the process of step S1407 is completed, the control unit 250 ends the process procedure shown in FIG.

Further, when the control unit 250 determines that the preparation change talk is not more than the maintenance talk (No in step S1403), there is a high possibility that the user U does not feel that the behavior has been changed, so the process is performed in step S1408. Proceed to. The control unit 250 determines whether or not the state in which the preparation change talk is not more than the maintenance talk is continuous for the determination period (step S1408). When it is determined that the determination period is not continuous (No in step S1408), the control unit 250 ends the processing procedure shown in FIG. In this disclosure, the operation of step S1408 may be omitted. That is, if the determination in step S1403 is No, the processing procedure may shift from step S1403 to step S1409.

If the control unit 250 determines that the determination period is continuous (Yes in step S1408), the control unit 250 determines that it is not the timing of behavior change, and proceeds to the process in step S1409. The control unit 250 shifts from Phase 4 to Phase 3 (step S1409). For example, the control unit 250 shifts (changes) the phase of the user U from the phase 4 to the phase 3, and reflects the shift to the phase 3 in the log information 330. The control unit 250 may perform a process of notifying the user U that the phase 2 has been started. When the process of step S1409 is completed, the control unit 250 ends the process procedure shown in FIG.

As a result, the control unit 250 has a phase 4 in which the user U feels that the behavior has been changed by executing the processing procedure shown in FIG. 16, and a phase 5 in which the new habit is watched so as to be established in the user U. Can be automatically migrated to. Further, the control unit 250 can automatically return from the phase 4 to the phase 3 when it is determined that it is not the timing of the behavior change.
