[Action information, schedule information, and performance information]
The interest level estimation system 10 estimates the level of interest of the guardian B in each of the plurality of genres using behavioral information indicating the behavior that the guardian B would like the infant A to engage in. Furthermore, the interest level estimation system 10 estimates the level of interest of the infant A in each of the plurality of genres using schedule information indicating the activity schedule of the infant A and performance information indicating the actual performance of the infant A. .

Below, an explanation will be given of an operation procedure for generating behavior information, schedule information, and performance information, and an example of an input screen. FIG. 2 is a flowchart showing the operating procedure. 3 to 9 are diagrams showing examples of input screens.

In the following description, it is assumed that the input operation for inputting the schedule information is performed by the guardian B. The input operation may be performed by the infant A. The input operation may be performed by at least one of the infant A and the guardian B. The input operations include operations performed in steps S11 to S16.

First, while a predetermined input screen (not shown) is being displayed on the display unit 22 of the first information terminal 20, the guardian B performs an operation to select an action that he/she wants the infant A to engage in during the target period of the next day. The operation accepting unit 21 accepts such a selection operation (S10). The input screen is displayed on the display unit 22, for example, by the control unit 23 executing an application program (hereinafter also referred to as the first application) dedicated to the interest level estimation system 10. The target period is, for example, a period of about one hour, but the length of the target period is not particularly limited.

In step S10, the guardian B specifically selects a candidate action that the infant A desires to perform from among the options. For example, about 10 to 50 options are prepared. Note that the guardian B can also freely input actions that are not included in the options.

Note that in step S10, the action may be selected in two stages, such as first selecting three or more candidates and then selecting one final candidate. The selection of the action in step S10 is, for example, made by the guardian B alone, and the child A is verbally informed that he or she wants the infant A to engage in the selected action during the target period the next day.

Next, Infant A and guardian B discuss what kind of behavior Infant A would like to perform during the following day's target period. Based on the result of the discussion, the guardian B performs an operation to select a candidate action that the infant A wishes to perform during the target period, and the operation reception unit 21 accepts such a selection operation (S11).

When the operation in step S11 is performed, a first input screen as shown in FIG. 3 is displayed on the display unit 22 of the first information terminal 20. For example, the control unit 23 causes the display unit 22 to display a schedule information input screen by executing the first application.

Specifically, when such a first input screen is displayed, the guardian B taps the icon labeled "Select" in FIG. 3 to input the information as shown in FIG. An option display screen (second input screen) can be displayed. Parent B selects a candidate action that infant A would like to perform from among the displayed options. For example, about 10 to 50 options are prepared. Note that the guardian B can also freely input actions that are not included in the options.

In step S11, for example, a plurality of candidates (specifically, a predetermined number or more) are selected. The predetermined number is, for example, three. At this time, the control unit 23 records the time required until each of the plurality of candidates is selected (S12). The time required until the first candidate is selected is the time from when the first input screen is displayed until the first candidate is selected, and the time required until the second candidate is selected. The required time is the time from when the first candidate is selected until when the second candidate is selected.

Note that the action (first action) selected in step S10 is not included in the candidates (second action) selected in step S11. In other words, the selection operation accepted in step S11 can be said to be an operation for selecting a second action other than the first action that the infant A desires to perform during the target period.

As a result, in step S11, an action is selected in which the influence of the intention of the guardian B is small and the intention of the infant A is strongly reflected, so that the accuracy of estimating the degree of interest of the infant A, which will be described later, is improved. Note that the first information terminal 20 (control unit 23) performs a process of not including the action selected in step S10 in the options displayed in step S11, and a process in which the same action as step S10 is selected in step S11. , processing that displays an error message, etc. may be performed.

When the reception of the candidate selection operation is completed, a third input screen as shown in FIG. 5 is displayed on the display unit 22. While such a third input screen is being displayed, infant A discusses actions that he or she particularly wants to carry out during the target period of the next day from among a plurality of candidates. Parent B performs a selection operation to select the final candidate based on the result of the discussion, and the operation reception unit 21 accepts such selection operation (S13).

In step S13, for example, the predetermined number of final candidates are selected. In the example shown in FIG. 5, three actions are selected as the final candidates from among the five action candidates: "television," "kazunosakuri," "drawing," "going to school," and "textbook."

When the acceptance of the final candidate selection operation is completed, a fourth input screen as shown in FIG. 6 is displayed on the display unit 22. While such a fourth input screen is being displayed, the infant A and the guardian B discuss the scheduled implementation order of the final candidates (three actions) during the target period. Based on the result of the discussion, the guardian B performs an operation to designate the scheduled implementation order of the determined plurality of final candidates during the target period, and the operation reception unit 21 accepts such a designation operation (S14).

When the acceptance of the operation for specifying the scheduled implementation order is completed, a fifth input screen as shown in FIG. 7 is displayed on the display unit 22. While such a fifth input screen is being displayed, infant A and guardian B discuss the time allocation for the final candidates (three actions) in the target period. Based on the result of the discussion, the guardian B performs an operation to designate the time allocation for the plurality of determined final candidates in the target period, and the operation reception unit 21 accepts such a designation operation (S15). As shown in FIG. 7, the time allocation designation operation is, for example, an operation on a triangular icon displayed on the fifth input screen. Note that the time allocation is specified in minimum units of approximately 5 to 10 minutes.

When the reception of the time allocation designation operation is completed, a sixth input screen as shown in FIG. 8 is displayed on the display unit 22. While such a sixth input screen is being displayed, infant A and guardian B discuss the start time of the target period. Parent B performs an operation to specify the start time of the target period based on the result of the discussion, and the operation reception unit 21 accepts such a specification operation (S16).

Next, the control unit 23 generates behavior information based on the selection operation accepted in step S10, and generates schedule information for infant A based on the input operation accepted in steps S11 to S16. The action information and schedule information are stored in the storage unit 24 (S17). FIG. 10 is a diagram showing an example of action information, schedule information, and performance information. As shown in FIG. 10, the schedule information includes the scheduled implementation date (the date following the day when the schedule information was input), (a) the action candidates selected on the scheduled implementation date, and (b) the candidates. The time required to be selected, (c) whether or not it has been selected as a final candidate, (d) the scheduled implementation order of the final candidate, and (e) the scheduled implementation time of the final candidate are associated. Note that the scheduled implementation time is determined by the above-mentioned time allocation designation operation. As shown in (b) and (c), the schedule information includes information obtained in connection with inputting a schedule. Further, as described later, the schedule information is associated with performance information. Note that the behavior information can also be considered as part of the schedule information.

Thereafter, at a predetermined time (for example, 10 minutes) before the start time of the target period specified in step S16, the control unit 23 causes the speaker to output an alarm sound (S18). The control unit 23 may vibrate the first information terminal 20 using a vibration motor (not shown) included in the first information terminal 20 instead of or in addition to the alarm sound.

Further, the control unit 23 causes the display unit 22 to display an input screen for performance information, which is the input screen shown in FIG.

When Infant A actually performs one of the three final candidate actions scheduled the previous day, Parent B performs a selection operation to select one action to be performed through the input screen of FIG. 9, and Tap the icon that says "Start activity." Further, the guardian B taps the icon labeled "End of activity" when finishing the implementation of the selected action. The operation reception unit 21 receives these input operations (S19), and the control unit 23 generates performance information based on the received input operations, and stores the generated performance information in association with the schedule information (S20). ). As shown in FIG. 10 above, in the performance information, (f) the order in which the actions of the final candidates were actually performed, and (g) the times in which the actions of the final candidates were actually performed are associated. There is.

As explained above, the guardian B can input behavior information, schedule information, and performance information through the first information terminal 20. Input of behavior information, schedule information, and performance information (a series of processes shown in FIG. 2) is performed daily, and the behavior information, schedule information, and performance information are accumulated in the storage unit 24. As will be described later, the accumulated behavior information, schedule information, and performance information are transmitted to the interest level estimation device 40 by the communication unit 25.

In addition, the control unit 23, triggered by a predetermined operation being performed on the first information terminal 20 (operation reception unit 21) running the first application, updates the schedule and performance of the action indicated by the schedule information. A comparison screen in which the results of the actions indicated by the information are arranged can be displayed on the display unit 22. FIG. 11 is a diagram showing an example of a comparison screen. In FIG. 11, the upper row shows the action schedule, and the lower row shows the action results. According to such a comparison screen, the infant A and the guardian B can look back on how the actual behavior compared to the planned behavior.

In addition, the control unit 23, triggered by a predetermined operation being performed on the first information terminal 20 (operation reception unit 21) that is running the first application, collects behavior information, schedule information, and performance information. Calendar information indicating whether or not information has been input for each date can be displayed. FIG. 12 is a diagram showing an example of calendar information. In the example of FIG. 12, a star-shaped stamp is stamped on the day when action information, schedule information, and performance information were input (corresponding to the date in FIG. 10), and action information, schedule information, and No stamps are affixed on days when performance information is not entered. According to such calendar information, the interest level estimation system 10 can increase the willingness of the infant A and the guardian B to input schedule information and performance information.

By the way, it is assumed that the operation for selecting an action and the operation for inputting schedule information are performed before going to bed on the day before the day on which the action is actually to be performed. Therefore, when the time before bedtime arrives (for example, the time between 9:00 p.m. and before 24:00) while the first application is running, the control unit 23 automatically transitions from the normal mode to the night mode. good. In the night mode, the control unit 23 lowers the brightness of the display unit 22 than in the normal mode, and lowers the output volume of the speaker 26 than in the normal mode. This prevents operations (information input) from interfering with sleep.

[Estimation motion 1: Estimation motion of infant's level of interest]
Estimation operation 1 for estimating the interest level of infant A using the schedule information and performance information input as described above will be described. FIG. 13 is a flowchart of operation 1 for estimating the degree of interest of infant A.

First, the communication unit 41 of the interest level estimation device 40 receives schedule information indicating the activity schedule of the infant A and performance information indicating the activity performance of the infant A from the first information terminal 20 (S21), and receives the information The processing unit 42 stores the received schedule information and performance information in the storage unit 43 (S22). For example, the schedule information and performance information are periodically transmitted from the first information terminal 20 to the interest level estimation device 40, but may also be transmitted non-regularly. The storage unit 43 stores (accumulates) schedule information and track record information for at least a predetermined period of time, and the interest level of infant A is estimated based on the schedule information and track record information for the predetermined period. The predetermined period is, for example, one month, but may be one week, and is not particularly limited.

After step S22, the communication unit 41 receives conversion parameter information from the second information terminal 30 (S23), and the information processing unit 42 stores the received conversion parameter information in the storage unit 43 (S24). First, conversion parameter information will be explained. FIG. 14 is a diagram showing an example of conversion parameter information.

As described later, the interest level estimation system 10 estimates the second level of interest of the infant A for each of the plurality of actions (that is, the level of interest for each action), and then estimates the second level of interest as: This is converted into the first degree of interest of the child A in each of the plurality of genres (that is, the degree of interest for each genre). The conversion parameter information is information used for this conversion, and converts the second degree of interest to the first degree of interest for each of the dozens to 50 types of action candidates (multiple action candidates prepared as options) described above. This is information (for example, table information) indicating coefficients (parameters) for converting into . In other words, the conversion parameter information is information indicating to what extent a certain behavior applies to each of a plurality of genres.

The plurality of genres here include, for example, four genres: Japanese, arithmetic, science, and social studies, but these genres are just one example. For example, the number of genres may be three or less, or five or more. Further, the plurality of genres may be genres that are different from the learning field (study subject), such as right brain type and left brain type.

The conversion parameter information is manually input into the second information terminal 30 by the teacher C. That is, the relationship between the behavior and the genre indicated by the conversion parameter information is based on teacher C's subjective evaluation. For example, the control unit 33 of the second information terminal 30 inputs conversion parameter information to the display unit 32 by executing a second application program (hereinafter also referred to as a second application) dedicated to the interest level estimation system 10. Display the screen. While the input screen is being displayed, the operation accepting unit 31 accepts from the teacher C an input operation for conversion parameter information (in the example of FIG. 14, numerical values from 1 to 5 in the table). The conversion parameter information input in this way is transmitted to the interest level estimation device 40 by the communication unit 35.

The conversion parameter information explained above is inputted by teacher C, and reflects the characteristics of the preschool classroom that toddler A attends (the school to which teacher C belongs) and the class content of the preschool classroom. . In other words, the conversion parameter information is different for each preschool classroom.

Next, the acquisition unit 44 acquires the schedule information and performance information of the infant A for the predetermined period from the storage unit 43 (S25), and the estimation unit 45 calculates a plurality of schedule information and performance information based on the acquired schedule information and performance information. The second degree of interest (second degree of interest information) of infant A with respect to each of the behaviors is estimated (S26). For example, the second degree of interest S of infant A in a certain action is estimated based on the following formula. The second degree of interest S has a value of 0 or more, and the larger the value, the higher the interest.

S=wa・Sa+wb・Sb+wc・Sc+wd・Sd
+we・Se+wf・Sf+wg・Sg

Sa to Sg in the above formula mean scores corresponding to the items (a) to (g) in FIG. 10, all of which are positive values. The maximum and minimum values of Sa to Sg are set to the same value.

For example, the score Sa is a score based on the cumulative number of times a certain behavior is selected as a candidate in a predetermined period, and the higher the cumulative number of times, the higher the value becomes. In other words, the score Sa becomes a higher value as the behavior is more likely to be selected as a candidate by the infant A.

The score Sb is a score based on the cumulative value of the time required to be selected as a candidate, and the smaller the cumulative value, the higher the value. In other words, the score Sb becomes a higher value as the behavior that the infant A selects as a candidate without hesitation.

The score Sc is a score based on the cumulative number of times a certain action is selected as a final candidate in a predetermined period, and the higher the cumulative number of times, the higher the value becomes. In other words, the score Sc becomes a higher value as the behavior is more likely to be selected as a final candidate by the infant A.

The score Sd is a score based on the average value of the scheduled implementation order, and the smaller the average scheduled implementation order, the higher the value. In other words, the score Sd has a higher value as the action is more likely to be planned by the infant A first.

The score Se is a score based on the cumulative value of scheduled implementation times, and the larger the cumulative value, the higher the value. In other words, the score Se takes on a higher value as the action is scheduled for a longer period of time for the infant A.

The score Sf is a score based on the average value of the implementation order, and the smaller the average implementation order, the higher the value. In other words, the score Sf has a higher value as the action is more likely to be performed by the infant A first.

The score Sg is a score based on the cumulative value of the implementation time, and the larger the cumulative value, the higher the value. In other words, the score Sg has a higher value as the action is performed by the infant A for a longer time.

Further, wa to wg are weights for the scores Sa to Sg, and are basically positive values, but may be 0. In other words, the second interest level S may be calculated using at least a portion of the scores Sa to Sg, and it is not essential that it be calculated using all of the scores Sa to Sg. Further, wa to wg may be negative values. The values of wa to wg may be appropriately set empirically or experimentally. For example, the score Sa is a score based on the cumulative number of times the candidate was selected, whereas the score Sc is a score based on the cumulative number of times the final candidate was selected. Therefore, the score Sc is higher than the score Sa. It is considered that the degree of influence on the degree of dual interest S is high. In such a case, wc>wa is set.

Next, the acquisition unit 44 acquires the conversion parameter information from the storage unit 43 (S27), and the estimation unit 45 converts the second interest level information obtained in step S26 into the second interest level information based on the acquired conversion parameter information. It is converted into single interest level information (S28). That is, the estimation unit 45 estimates the first degree of interest of the infant A in each of the plurality of genres based on the estimated second degree of interest and the acquired conversion parameter information. FIG. 15 is a diagram for explaining a method of converting second degree of interest information into first degree of interest information.

The estimating unit 45 calculates each numerical value (that is, the second interest level) in the second interest level column of the second interest level information in FIG. 15(a) and the "Japanese language" By multiplying each value (coefficient) in the "Japanese language series" column and summing the multiplied values, it is possible to calculate the primary interest level for "Japanese language series." Similarly, the estimating unit 45 calculates the first degree of interest for each of "arithmetic," "science," and "social studies," and normalizes the calculated first degree of interest. As a result, as shown in FIG. 15(c), first interest level information indicating the first interest level of infant A in each of the plurality of genres is obtained. That is, the estimation unit 45 can convert the second degree of interest information (second degree of interest) into first degree of interest information (first degree of interest).

The output unit 46 outputs the first interest level information obtained in step S28 (S29), and causes the communication unit 41 to transmit the output first interest level information to the second information terminal 30 (S30). The communication unit 35 of the second information terminal 30 receives the first degree of interest information, and the control unit 33 causes the display unit 32 to display an image indicating the received first degree of interest information. FIG. 16 is a diagram illustrating an example of an image indicating first interest level information.

In this way, if the degree of interest of the child A for each genre (study field) is displayed on the display unit 32, the teacher C can grasp the degree of interest of the child A and use it for teaching the child A. In other words, the interest level estimation system 10 can assist the teacher C in understanding the interest level of the child A by providing the interest level for the genre. Teacher C who is provided with the level of interest in genres corresponding to the superordinate concept of behavior will be able to more easily formulate guidelines for the education of child A than in the case where teacher C is provided with the level of interest in behavior. For example, when comparing the case where information is provided that the person is interested in playing with blocks and the case where the information is provided that the person is interested in arithmetic, Teacher C feels that the latter is better for teaching guidelines (what kind of teaching materials It is easy to make decisions (e.g., what should I prepare?).

Note that in step S<b>30 , the communication unit 41 may transmit the first interest level information to the first information terminal 20 instead of or in addition to the second information terminal 30 . In this case, the communication unit 25 of the first information terminal 20 receives the first degree of interest information, and the control unit 23 causes the display unit 22 to display an image indicating the received first degree of interest information.

In this way, if the interest level of the toddler A for each genre (study field) is displayed on the display unit 22, the guardian B of the toddler A can grasp the toddler A's level of interest. In other words, the interest level estimation system 10 can assist the guardian B in understanding the interest level of the child A by providing the interest level for the genre. Parents who are provided with the level of interest in a genre corresponding to a superordinate concept of behavior will be able to more easily formulate educational guidelines for Infant A than if they are provided with the level of interest in the behavior. For example, when Parent B is provided with information that he is interested in playing with blocks and when he is provided with information that he is interested in mathematics, Parent B feels that the latter is better for educational guidelines (what kind of educational guidelines). It is easy to decide whether to prepare teaching materials, etc.).

Further, in the estimation operation 1, the acquisition unit 44 acquired both the schedule information and the performance information, but the acquisition unit 44 only needs to acquire at least the schedule information. That is, in the estimation operation 1, only the schedule information may be used in the portion where it is explained that both the schedule information and the performance information are used.

Further, the formula used to estimate the second degree of interest in the estimation operation 1 is just an example, and the formula for estimating the second degree of interest may be appropriately determined empirically or experimentally. Furthermore, a machine learning model may be used to estimate the second degree of interest. Such a machine learning model inputs schedule information and performance information (at least schedule information) and outputs second interest level information. A machine learning model can construct, as learning data, schedule information and performance information (at least schedule information) to which subjective evaluation results of the degree of interest regarding each action are assigned as correct answer labels.

[Estimated action 2: Estimated action of guardian's level of interest]
Next, estimation operation 2 for estimating the degree of interest of guardian B using the behavior information input as described above will be described. FIG. 17 is a flowchart of estimation operation 2 (operation for estimating the degree of interest of guardian B).

First, the communication unit 41 of the interest level estimation device 40 receives behavior information from the first information terminal 20 (S31), and the information processing unit 42 stores the received behavior information in the storage unit 43 (S32). For example, the behavior information is periodically transmitted from the first information terminal 20 to the interest level estimation device 40, but may be transmitted non-regularly. The behavior information may be transmitted together with the schedule information and performance information, or may be transmitted separately from the schedule information and performance information. Behavior information is stored (accumulated) in the storage unit 43 for at least a predetermined period of time, and the interest level of guardian B is estimated based on the behavior information for the predetermined period of time. The predetermined period is, for example, one month, but may be one week, and is not particularly limited.

After step S32, the communication unit 41 receives conversion parameter information from the second information terminal 30 (S33), and the information processing unit 42 stores the received conversion parameter information in the storage unit 43 (S34). Note that in the case where the conversion parameter information is already stored in the storage unit 43. The processes of steps S33 and S34 are omitted.

Next, the acquisition unit 44 acquires the behavior information for the predetermined period from the storage unit 43 (S35), and the estimation unit 45 determines whether the guardian B will interact with the infant A during the predetermined period based on the acquired behavior information. The number of selections for each of the one or more actions that the user wants to take is counted (S36).

Next, the acquisition unit 44 acquires conversion parameter information from the storage unit 43 (S37), and the estimation unit 45 converts the total result in step S36 into third interest degree information based on the acquired conversion parameter information. (S38). That is, the estimating unit 45 estimates the degree of interest of the guardian B in each of the plurality of genres based on the total result of the number of times the behavior is selected and the acquired conversion parameter information. FIG. 18 is a diagram for explaining a method of converting the total result into third interest level information.

The estimating unit 45 multiplies each numerical value in the selection frequency column of the tally result in FIG. 18(a) by each numerical value (coefficient) in the "Japanese language" column of the conversion parameter information in FIG. 18(b). By summing the combined and multiplied values, it is possible to calculate the third degree of interest in "Japanese language". Similarly, the estimation unit 45 calculates the third degree of interest for each of "arithmetic," "science," and "social studies," and normalizes the calculated third degree of interest. As a result, as shown in FIG. 18(c), third degree of interest information indicating the third degree of interest of guardian B in each of the plurality of genres is obtained. That is, the estimation unit 45 can convert the total result into third interest degree information (third interest degree).

The output unit 46 outputs the third degree of interest information obtained in step S38 (S39), and causes the communication unit 41 to transmit the output third degree of interest information to the second information terminal 30 (S40). The communication unit 35 of the second information terminal 30 receives the third degree of interest information, and the control unit 33 causes the display unit 32 to display an image indicating the received third degree of interest information. The image at this time is similar to that shown in FIG.

In this way, if the degree of interest of guardian B for each genre (study field) is displayed on the display unit 32, teacher C can grasp the degree of interest of guardian B and use it for teaching infant A. can. In other words, the interest level estimation system 10 can assist the teacher C in understanding the interest level of the guardian B by providing the interest level for the genre.

Note that in step S<b>40 , the communication unit 41 may transmit the third interest level information to the first information terminal 20 instead of or in addition to the second information terminal 30 . In this case, the communication unit 25 of the first information terminal 20 receives the third degree of interest information, and the control unit 23 causes the display unit 22 to display an image indicating the received third degree of interest information.

In this way, if guardian B's interest level for each genre (study field) is displayed on the display unit 22, guardian B can grasp his or her own interest level.

Further, in the estimation operation 2, the acquisition unit 44 acquired the behavior information (planned number of times the behavior is performed), but in addition to the behavior information, the acquisition unit 44 also acquires the number of times the behavior selected as the behavior information is performed (actual ) may be obtained. In this case, the number of times the selected behavior has been performed as behavior information is accumulated in the storage unit 24 of the first information terminal 20, similar to performance information, and provided to the interest level estimation device 40.

Based on the acquired behavior information, the estimation unit 45 totals the total number of selections and implementation times of each of the one or more behaviors that the guardian B wants the infant A to engage in during a predetermined period. In other words, the numerical value in the selection count column in FIG. 18 is the total value of the selection count and the execution count. When summing the number of selections and the number of implementations, a weight may be set for each of the number of selections and the number of implementations, and the number of selections and the number of implementations after weighting may be summed.

[Suggested action]
The interest level estimation system 10 can also perform a proposing operation that proposes an action suitable for the infant A based on the interest levels of the infant A and the guardian B. FIG. 19 is a flowchart of the proposed operation.

First, the estimation unit 45 of the interest level estimating device 40 estimates the first interest level of the infant A by performing the above estimation operation 1 (S51). Specifically, the estimation unit 45 estimates the first degree of interest of the infant A in each of the plurality of genres based on the schedule information acquired by the acquisition unit 44.

Next, the estimation unit 45 estimates the third degree of interest of the guardian B by performing the estimation operation 2 described above (S52). Specifically, the estimation unit 45 estimates the third degree of interest of the guardian B in each of the plurality of genres based on the behavior information acquired by the acquisition unit 44.

Next, the output unit 46 determines a behavior to be proposed to the infant A and the guardian B based on the estimated first degree of interest of the infant A and the third degree of interest of the guardian B (S53 ).

Here, the candidate actions to be proposed are the dozens to 50 types of actions described above (a plurality of actions prepared as options). The above-mentioned conversion parameters are set for these actions. In other words, coefficients indicating the degree of relevance to each of a plurality of genres are determined for candidate actions to be proposed.

The output unit 46 specifies the genre (also described as the second genre) in which the first degree of interest of the infant A estimated in step S51 is highest, and the genre in which the third degree of interest of the guardian B estimated in step S52 is the highest. Identify the highest genre (also referred to as the first genre). The output unit 46 selects, from among the candidate actions to be proposed, actions in which both the coefficient for the first genre and the coefficient for the second genre are larger than a predetermined value, as the actions to be proposed (toward infant A). actions considered appropriate).

For example, if the first genre is Japanese and the second genre is Arithmetic, the actions for which the coefficients of Japanese and Arithmetic are equal to or higher than the first predetermined value (for example, 4) are the actions to be proposed. (The action that Infant A should take from now on) is determined. If there are multiple applicable actions, all of them may be determined as the action to be proposed, or the action with the largest sum of the Japanese language coefficient and the arithmetic coefficient will be the action to be proposed. It may be determined as follows, or a portion of the actions may be randomly determined as the target of the proposal.

In addition, when the first genre and the second genre are the same, such as when the first genre and the second genre are both Japanese, for example, the coefficient of the second genre is larger than the first predetermined value. Actions that are equal to or greater than a predetermined value (for example, 4.5) are determined as actions to be proposed. In this case, if there are multiple applicable actions, all of them may be determined as the action to be proposed, or the action with the largest coefficient for the genre may be determined as the action to be proposed. Alternatively, a portion of the actions may be randomly determined as the target of the proposal.

Next, the output unit 46 generates proposal information for proposing the action to be proposed determined in step S53, and outputs the generated proposal information (S54). The output unit 46 causes the communication unit 41 to transmit such proposal information to the second information terminal 30 (S55). The communication unit 35 of the second information terminal 30 receives the proposal information, and the control unit 33 causes the display unit 32 to display a proposal image as shown in FIG. 20, for example, based on the received proposal information. FIG. 20 is a diagram illustrating an example of a proposed image.

Note that if the proposal information includes the first degree of interest information obtained as a result of the process in step S51 and the third degree of interest information obtained as a result of the process in step S52, the first degree of interest information, Furthermore, the third degree of interest information can also be visualized (graphed).

Note that the first interest level information and the third interest level information may be visualized individually as a pie chart as shown in FIG. 16, but in the example of FIG. The first degree of interest and the third degree of interest of guardian B in each of the plurality of genres are displayed superimposed on one radar chart. According to the display mode of the first interest level information and the third interest level information, the teacher C can easily tell the difference between the first interest level of the child A and the third interest level of the guardian B. can be grasped.

In this way, if the actions to be proposed to the child A and the guardian B are presented to the teacher C, the teacher C can use this as a reference to formulate educational guidelines.

Note that in step S55, the communication unit 41 may transmit the proposal information to the first information terminal 20 instead of or in addition to the second information terminal 30. In this case, the communication unit 25 of the first information terminal 20 receives the proposal information, and the control unit 23 causes the display unit 22 to display the proposal image based on the received proposal information.

In this way, if the behavior is directly presented to the infant A and the guardian B, the infant A and the guardian B can refer to this and formulate educational guidelines.

Note that a business providing a service using the interest level estimation system 10 (interest level estimation device 40) may provide the teacher C or the guardian B with a report (paper) corresponding to the above-mentioned proposed image.

Further, in the suggestion image, it is sufficient that at least the action to be proposed is displayed, and it is not essential that the first interest level information and the third interest level information be visualized in the suggestion image. For example, the output unit 46 may display display information for displaying both the first degree of interest and the third degree of interest (contents of both the first degree of interest information and the third degree of interest information) in addition to the proposal information. (including information) can also be output. In other words, the output unit 46 outputs information for displaying only the graph portion of the proposed image in FIG. It is also possible to display only a portion.
