[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection forms, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components not recited in independent claims will be described as optional components.

[0011] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0012] (Embodiment) [composition] First, the configuration of the level of interest estimating system according to the embodiment will be described below. Fig. 1 is a block diagram showing the functional configuration of the level of interest estimating system according to the embodiment.

[0013] The interest level estimation system 10 according to the embodiment is a system that can estimate the interest levels of infant A and parent B in each of a plurality of genres related to possible behaviors of infant A. The interest level is a parameter that indicates how interested infant A or parent B is in that genre, or in other words, the interest level.

[0014] The actions here are actions that infant A can take, such as going to the park, playing with blocks, drawing, studying numbers, and studying letters. Actions can be rephrased as activities or actions. Genres correspond to higher concepts of actions, and can be rephrased as fields, classifications, or types. In the following embodiments, genres are learning-related genres (in other words, learning fields), such as Japanese language, arithmetic, science, etc.

[0015] 1, the degree of interest estimating system 10 includes a first information terminal 20, a second information terminal 30, and a degree of interest estimating device 40. Each of these devices will be described below.

[0016] [First information terminal] First, the first information terminal 20 will be described. The first information terminal 20 is an information terminal used by the infant A or the guardian B. The first information terminal 20 is, for example, a portable information terminal such as a smartphone or a tablet terminal, but may also be a stationary information terminal such as a personal computer. Specifically, the first information terminal 20 includes an operation reception unit 21, a display unit 22, a control unit 23, a storage unit 24, a communication unit 25, and a speaker 26.

[0017] The operation receiving unit 21 receives operations from Infant A or guardian B. For example, the operation receiving unit 21 receives input operations from Infant A or guardian B, such as schedule information indicating the planned behavior of Infant A and performance information indicating the performance of Infant A's behavior. The operation receiving unit 21 is realized by, for example, a touch panel, but may also be realized by a mouse and keyboard, etc.

[0018] The display unit 22 displays an image. The display unit 22 displays, for example, an input screen for schedule information and performance information. The display unit 22 is realized by, for example, a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel.

[0019] The control unit 23 performs control such as causing the communication unit 25 to transmit the schedule information and performance information input to the operation receiving unit 21 to the interest level estimating device 40. The control unit 23 is realized, for example, by a microcomputer or may be realized by a processor. The functions of the control unit 23 are realized, for example, by the microcomputer or processor constituting the control unit 23 executing a computer program stored in the storage unit 24.

[0020] The storage unit 24 is a storage device that stores computer programs and the like executed by the control unit 23. The storage unit 24 is realized by, for example, a semiconductor memory.

[0021] The communication unit 25 is a communication module (communication circuit) that enables the first information terminal 20 to communicate with the degree of interest estimating device 40 via a wide area communication network 70 such as the Internet. The communication unit 25 transmits, for example, schedule information and performance information to the degree of interest estimating device 40. The communication performed by the communication unit 25 is, for example, wireless communication, but may also be wired communication. There is no particular limitation on the communication standard used for the communication.

[0022] The speaker 26 outputs sounds such as an alarm sound, etc. The speaker 26 is a speaker built into the first information terminal 20, but may also be a speaker attached externally to the first information terminal 20.

[0023] [Second information terminal] Next, the second information terminal 30 will be described. The second information terminal 30 is an information terminal used by a teacher C of an early childhood classroom (a school for preschool children) attended by an infant A. The second information terminal 30 is, for example, a portable information terminal such as a smartphone or a tablet terminal, but may also be a stationary information terminal such as a personal computer. Specifically, the second information terminal 30 includes an operation receiving unit 31, a display unit 32, a control unit 33, a storage unit 34, and a communication unit 35.

[0024] The operation receiving unit 31 receives operations from the teacher C. The operation receiving unit 31 receives, for example, an input operation of conversion parameter information from the teacher C. The conversion parameter information will be described later. The multiple operation receiving units 31 are realized, for example, by a touch panel, but may also be realized by a mouse, keyboard, etc.

[0025] The display unit 32 displays an image. For example, the display unit 32 displays an input screen for conversion parameter information. The display unit 32 is realized by a display panel such as a liquid crystal panel or an organic EL panel.

[0026] The control unit 33 controls the communication unit 35 to transmit the conversion parameter information input to the operation receiving unit 31 to the degree of interest estimating device 40. The control unit 33 is realized, for example, by a microcomputer or may be realized by a processor. The functions of the control unit 33 are realized, for example, by the microcomputer or processor constituting the control unit 33 executing a computer program stored in the storage unit 34.

[0027] The storage unit 34 is a storage device that stores computer programs and the like executed by the control unit 33. The storage unit 34 is realized by, for example, a semiconductor memory.

[0028] The communication unit 35 is a communication module (communication circuit) that enables the second information terminal 30 to communicate with the degree of interest estimating device 40 via the wide area communication network 70. The communication unit 35 transmits, for example, conversion parameter information to the degree of interest estimating device 40. The communication performed by the communication unit 35 is, for example, wireless communication, but may also be wired communication. There is no particular limitation on the communication standard used for the communication.

[0029] [Interest Level Estimation Device] Next, a description will be given of the degree of interest estimating device 40. The degree of interest estimating device 40 is a cloud server (server device) that performs information processing to estimate the degrees of interest of infant A and guardian B based on information received from the first information terminal 20 and information received from the second information terminal 30. The degree of interest estimating device 40 includes a communication unit 41, an information processing unit 42, and a storage unit 43.

[0030] The communication unit 41 is a communication module (communication circuit) that enables the degree of interest estimating device 40 to communicate with the first information terminal 20 and the second information terminal 30 via the wide area communication network 70. The communication performed by the communication unit 41 is, for example, wired communication, but may also be wireless communication. There is no particular limitation on the communication standard used for the communication.

[0031] The information processing unit 42 performs information processing to estimate the interest levels of infant A and guardian B. The information processing unit 42 is realized, for example, by a microcomputer, but may also be realized by a processor. The information processing unit 42 has, as functional components, an acquisition unit 44, an estimation unit 45, and an output unit 46. The functions of the acquisition unit 44, the estimation unit 45, and the output unit 46 are realized, for example, by a microcomputer or a processor constituting the information processing unit 42 executing a computer program stored in the storage unit 43. The detailed functions of the acquisition unit 44, the estimation unit 45, and the output unit 46 will be described later.

[0032] The storage unit 43 is a storage device that stores the computer program executed by the information processing unit 42 and various information used to perform the above information processing. The storage unit 43 is realized by, for example, an HDD (Hard Disk Drive).

[0033] [Behavioral information, schedule information, and performance information] The interest level estimation system 10 estimates the interest level of guardian B in each of a plurality of genres using behavioral information indicating behaviors that guardian B wants infant A to undertake. The interest level estimation system 10 also estimates the interest level of infant A in each of a plurality of genres using schedule information indicating the planned behavior of infant A and performance information indicating the performance of infant A's behavior.

[0034] The following describes the operation procedures for generating behavior information, schedule information, and performance information, and examples of input screens. Fig. 2 is a flowchart showing the operation procedures. Figs. 3 to 9 are diagrams showing examples of input screens.

[0035] In the following description, the input operation for inputting schedule information is assumed to be performed by guardian B. The input operation may also be performed by infant A. The input operation may be performed by at least one of infant A and guardian B. The input operation includes the operations performed in steps S11 to S16.

[0036] First, when a predetermined input screen (not shown) is displayed on the display unit 22 of the first information terminal 20, the guardian B performs an operation to select an activity that the guardian B wants the infant A to engage in during a target period of the next day, and the operation receiving unit 21 receives 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 a first app) dedicated to the interest level estimation system 10. The target period is, for example, about one hour long, but the length of the target period is not particularly limited.

[0037] In step S10, parent B specifically selects a candidate behavior that child A wishes to perform from among the options. For example, several tens to about 50 options are prepared. Parent B can also freely input an action that is not included in the options.

[0038] In step S10, the behavior may be selected in two stages, such as first selecting three or more candidates and then selecting one final candidate. The behavior selection in step S10 may be performed by, for example, guardian B alone, who verbally informs infant A that he or she wants infant A to engage in the selected behavior during the target period the next day.

[0039] Next, Infant A and guardian B discuss what kind of behavior Infant A would like to perform during the target period on the following day. Based on the results of the discussion, guardian B performs a selection operation of a candidate behavior that Infant A would like to perform during the target period, and the operation receiving unit 21 receives this selection operation (S11).

[0040] When the operation of step S11 is performed, a first input screen as shown in Fig. 3 is displayed on display unit 22 of first information terminal 20. For example, control unit 23 executes the first application to cause display unit 22 to display an input screen for schedule information.

[0041] When such a first input screen is displayed, parent B can tap the icon labeled "Select" in FIG. 3 to display a screen displaying options (second input screen) as shown in FIG. 4. Parent B selects a candidate action that infant A wishes to perform from the displayed options. For example, several tens to 50 options are prepared. Parent B can also freely input an action that is not included in the options.

[0042] 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 for each of the plurality of candidates to be selected (S12). Note that the time required for the first candidate to be selected is the time from when the first input screen is displayed until the first candidate is selected, and the time required for the second candidate to be selected is the time from when the first candidate is selected until the second candidate is selected.

[0043] The behavior (first behavior) selected in step S10 is not included in the candidates (second behaviors) selected in step S11. In other words, the selection operation accepted in step S11 can be said to be an operation of selecting a second behavior other than the first behavior that infant A wishes to perform during the target period.

[0044] As a result, in step S11, an action that is less influenced by the intentions of guardian B and strongly reflects the intentions of infant A is selected, thereby improving the accuracy of estimating the level of interest of infant A, which will be described later. Note that the first information terminal 20 (control unit 23) may perform processing such as not including the action selected in step S10 in the options displayed in step S11, and displaying an error message when the same action as in step S10 is selected in step S11.

[0045] When the acceptance 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 displayed, infant A discusses from among the multiple candidates which activity he or she would particularly like to perform during the target period the next day. Based on the results of the discussion, guardian B performs a selection operation to select a final candidate, and the operation acceptance unit 21 accepts such a selection operation (S13).

[0046] In step S13, the predetermined number of final candidates are selected, for example. In the example of Fig. 5, three actions are selected as final candidates from five action candidates: "TV," "Study numbers," "Drawing," "Go to the park," and "Building blocks."

[0047] When the acceptance of the selection operation of the final candidates 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 displayed, infant A and guardian B discuss the planned implementation order of the final candidates (three actions) for the target period. Based on the result of the discussion, guardian B performs an operation to specify the planned implementation order of the determined multiple final candidates for the target period, and the operation acceptance unit 21 accepts such a specification operation (S14).

[0048] When the acceptance of the operation for specifying the scheduled execution order is completed, a fifth input screen as shown in FIG. 7 is displayed on the display unit 22. While this fifth input screen is displayed, infant A and guardian B discuss the time allocation of the final candidates (three activities) for the target period. Based on the results of the discussion, guardian B performs an operation for specifying the time allocation of the determined final candidates for the target period, and the operation acceptance unit 21 accepts this specification operation (S15). As shown in FIG. 7, the operation for specifying the time allocation is, for example, an operation on a triangular icon displayed on the fifth input screen. Note that the time allocation is specified in the minimum unit of about 5 to 10 minutes.

[0049] When the acceptance of the time allocation designation operation is completed, the display unit 22 displays a sixth input screen as shown in Fig. 8. While such a sixth input screen is displayed, infant A and guardian B discuss the start time of the target period. Based on the result of the discussion, guardian B performs an operation to designate the start time of the target period, and the operation acceptance unit 21 accepts such designation operation (S16).

[0050] Next, the control unit 23 generates behavioral information based on the selection operation received in step S10, generates schedule information for infant A based on the input operations received in steps S11 to S16, and stores the generated behavioral information and schedule information in the storage unit 24 (S17). FIG. 10 is a diagram illustrating examples of behavioral information, schedule information, and performance information. As shown in FIG. 10, the schedule information associates the scheduled implementation date (the date following the day on which the schedule information is input), (a) candidate activities selected for the scheduled implementation date, (b) the time required for the candidate to be selected, (c) whether or not the candidate is selected as a final candidate, (d) the scheduled implementation order of the final candidate, and (e) the scheduled implementation time of the final candidate. Note that the scheduled implementation time is determined by the time allocation specification operation described above. As shown in (b) and (c), the schedule information includes information obtained in connection with the input of the schedule. Furthermore, as will be described later, performance information is associated with the schedule information. Note that the behavioral information can also be considered as part of the schedule information.

[0051] Thereafter, at a predetermined time (for example, 10 minutes) before the start time of the target period designated in step S16, control unit 23 outputs an alarm sound from the speaker (S18). Instead of or in addition to the alarm sound, control unit 23 may vibrate first information terminal 20 using a vibration motor (not shown) provided in first information terminal 20.

[0052] Furthermore, the control unit 23 causes the display unit 22 to display an input screen for inputting performance information, which is the input screen shown in FIG.

[0053] When parent B is going to have infant A actually perform one of the three final candidate actions scheduled for the previous day, parent B performs a selection operation to select one of the actions to be performed through the input screen of FIG. 9 and taps on the icon labeled "Start Activity." Parent B also taps on the icon labeled "End Activity" when completing the selected action. The operation receiving 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, the performance information associates (f) the order in which the final candidate actions were actually performed with (g) the time at which the final candidate actions were actually performed.

[0054] As described above, the guardian B can input behavioral information, schedule information, and achievement information through the first information terminal 20. The input of behavioral information, schedule information, and achievement information (a series of processes shown in FIG. 2 ) is performed daily, and the behavioral information, schedule information, and achievement information are accumulated in the storage unit 24. As will be described later, the accumulated behavioral information, schedule information, and achievement information are transmitted to the interest level estimating device 40 by the communication unit 25.

[0055] When a predetermined operation is performed on the first information terminal 20 (operation receiving unit 21) running the first application, the control unit 23 can display on the display unit 22 a comparison screen in which the planned behavior indicated by the schedule information and the actual behavior indicated by the actual behavior information are arranged side by side. Fig. 11 is a diagram showing an example of the comparison screen. In Fig. 11, the upper row shows the planned behavior, and the lower row shows the actual behavior. This comparison screen allows infant A and guardian B to look back on how the actual behavior was compared to the planned behavior.

[0056] Furthermore, when a predetermined operation is performed on the first information terminal 20 (the operation receiving unit 21) while the first application is running, the control unit 23 can display calendar information indicating, for each date, whether or not behavioral information, schedule information, and achievement information have been input. 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 on which behavioral information, schedule information, and achievement information have been input (corresponding to the dates in FIG. 10), and no stamp is stamped on the day on which behavioral information, schedule information, and achievement information have not been input. Using such calendar information, the interest level estimating system 10 can increase the motivation of infant A and guardian B to input schedule information and achievement information.

[0057] It is assumed that the operation of selecting an action and the operation of inputting schedule information are performed in the time period before going to bed on the day before the action is actually performed. Therefore, when the time period before going to bed (for example, the time period after 9 PM and before midnight) arrives while the first application is being executed, the control unit 23 may automatically transition from the normal mode to the night mode. In the night mode, the control unit 23 reduces the brightness of the display unit 22 compared to the normal mode and also reduces the output volume of the speaker 26 compared to the normal mode. This prevents the operation (information input) from interfering with sleep.

[0058] [Estimated Action 1: Estimating the level of interest in young children] A description will be given of an estimating operation 1 for estimating the interest level of infant A using the schedule information and performance information input as described above. Fig. 13 is a flowchart of the estimating operation 1 for estimating the interest level of infant A.

[0059] First, the communication unit 41 of the level of interest estimating device 40 receives schedule information indicating a schedule of infant A's behavior and achievement information indicating achievements of infant A's behavior from the first information terminal 20 (S21), and the information processing unit 42 stores the received schedule information and achievement information in the storage unit 43 (S22). The schedule information and achievement information are, for example, periodically transmitted from the first information terminal 20 to the level of interest estimating device 40, but may also be transmitted aperiodically. The storage unit 43 stores (accumulates) the schedule information and achievement information for at least a predetermined period, and the level of interest of infant A is estimated based on the schedule information and achievement information for the predetermined period. The predetermined period is, for example, one month, but may also be one week, and is not particularly limited.

[0060] After step S22, the communication unit 41 receives the 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, the conversion parameter information will be described. Fig. 14 is a diagram showing an example of the conversion parameter information.

[0061] As will be described later, the interest level estimation system 10 estimates the second level of interest of infant A in each of a plurality of behaviors (i.e., the level of interest for each behavior), and then converts the second level of interest into the first level of interest of infant A in each of a plurality of genres (i.e., the level of interest for each genre). The conversion parameter information is information used for this conversion, and is information (e.g., table information) indicating coefficients (parameters) for converting the second level of interest in each of the several tens to 50 types of behavior candidates (a plurality of behavior candidates prepared as options) into the first level of interest. In other words, the conversion parameter information is information indicating to what extent a certain behavior fits into each of a plurality of genres.

[0062] The multiple genres here are, for example, four: Japanese, arithmetic, science, and social studies, but these genres are just an example. For example, the number of multiple genres may be three or less, or five or more. Furthermore, the multiple genres may be genres with approaches different from the learning fields (learning subjects), such as right-brain and left-brain.

[0063] 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 the subjective evaluation of the teacher C. For example, the control unit 33 of the second information terminal 30 executes a second application program (hereinafter also referred to as a second app) dedicated to the level of interest estimating system 10, thereby causing the display unit 32 to display an input screen for the conversion parameter information. While the input screen is displayed, the operation accepting unit 31 accepts an input operation for the conversion parameter information (in the example of FIG. 14 , the numerical values ​​1 to 5 in the table) from the teacher C. The conversion parameter information thus input is transmitted to the level of interest estimating device 40 by the communication unit 35.

[0064] The conversion parameter information described above is input by teacher C, and reflects the characteristics of the preschool classroom (the school to which teacher C belongs) attended by child A, the content of lessons at that preschool, etc. In other words, the conversion parameter information is different for each preschool classroom.

[0065] Next, the acquisition unit 44 acquires schedule information and performance information of infant A for the predetermined period from the storage unit 43 (S25), and the estimation unit 45 estimates infant A's second level of interest (second interest level information) in each of the multiple behaviors based on the acquired schedule information and performance information (S26). For example, infant A's second level of interest S in a certain behavior is estimated based on the following formula. The second level of interest S is a value equal to or greater than 0, with a larger value indicating a higher level of interest.

[0066] S=wa·Sa+wb·Sb+wc·Sc+wd·Sd +we·Se+wf·Sf+wg·Sg

[0067] In the above formula, Sa to Sg mean scores corresponding to the items (a) to (g) in Fig. 10, and all of them are positive values. The maximum and minimum values ​​of each of Sa to Sg are set to the same value.

[0068] For example, the score Sa is a score based on the cumulative number of times a certain behavior has been selected as a candidate during a predetermined period, and the more the cumulative number, the higher the value. In other words, the more likely a behavior is to be selected as a candidate by infant A, the higher the score Sa will be.

[0069] The score Sb is based on the cumulative value of the time required for selection as a candidate, and the smaller the cumulative value, the higher the score Sb. In other words, the more easily Infant A selects an action as a candidate, the higher the score Sb.

[0070] The score Sc is based on the cumulative number of times that a certain behavior has been selected as a final candidate within a predetermined period, and the more the cumulative number, the higher the value. In other words, the more likely a behavior is to be selected as a final candidate by Infant A, the higher the score Sc will be.

[0071] The score Sd is based on the average value of the scheduled execution order, and the smaller the average scheduled execution order, the higher the score Sd. In other words, the more likely a behavior is to be scheduled first by infant A, the higher the score Sd will be.

[0072] The score Se is a score based on the cumulative value of the scheduled execution time, and the larger the cumulative value, the higher the score Se. In other words, the longer the scheduled time for an action for infant A, the higher the score Se.

[0073] The score Sf is based on the average value of the execution order, and the smaller the average execution order, the higher the score Sf. In other words, the more likely an action is to be performed first by infant A, the higher the score Sf.

[0074] The score Sg is based on the cumulative value of the duration of the behavior, and the larger the cumulative value, the higher the score Sg. In other words, the longer the behavior is performed by the infant A, the higher the score Sg.

[0075] Furthermore, 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 some of the scores Sa to Sg, and it is not necessary to calculate it using all of the scores Sa to Sg. Furthermore, wa to wg may be negative values. The values ​​of wa to wg may be set empirically or experimentally as appropriate. For example, the score Sa is based on the cumulative number of times selected as a candidate, while the score Sc is based on the cumulative number of times selected as a final candidate, so it is considered that the score Sc has a greater influence on the second interest level S than the score Sa. In such a case, the relationship wc>wa is set.

[0076] Next, the acquisition unit 44 acquires 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 first interest level information based on the acquired conversion parameter information (S28). That is, the estimation unit 45 estimates the first interest level of child A in each of a plurality of genres based on the estimated second interest level and the acquired conversion parameter information. Fig. 15 is a diagram for explaining a method for converting the second interest level information into first interest level information.

[0077] The estimation unit 45 multiplies each value (i.e., second interest level) in the second interest level column of the second interest level information in FIG. 15(a) by each value (coefficient) in the "Japanese language" column of the conversion parameter information in FIG. 15(b), and then sums the resulting multiplications to calculate the first interest level in "Japanese language." Similarly, the estimation unit 45 calculates the first interest level for each of "arithmetic," "science," and "social studies," and normalizes the calculated first interest levels. As a result, first interest level information indicating the first interest level of infant A in each of multiple genres is obtained, as shown in FIG. 15(c). In other words, the estimation unit 45 can convert the second interest level information (second interest level) into first interest level information (first interest level).

[0078] 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 interest level information, and the control unit 33 causes the display unit 32 to display an image indicating the received first interest level information. Fig. 16 is a diagram showing an example of the image indicating the first interest level information.

[0079] In this way, if Infant A's level of interest in each genre (learning field) is displayed on the display unit 32, Teacher C can grasp Infant A's level of interest and use this information to help teach Infant A. In other words, the interest level estimation system 10 can assist Teacher C in grasping Infant A's level of interest by providing the level of interest in genres. When Teacher C is provided with the level of interest in genres that correspond to higher concepts of behavior, it becomes easier to formulate educational guidelines for Infant A than when Teacher C is provided with the level of interest in behavior. For example, comparing the case where Teacher C is provided with information that Infant A is interested in playing with blocks with the case where Teacher C is provided with information that Infant A is interested in arithmetic, Teacher C finds it easier to formulate educational guidelines (such as what kind of teaching materials to prepare) in the latter case.

[0080] In step S30, 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 interest level information, and the control unit 23 causes the display unit 22 to display an image indicating the received first interest level information.

[0081] In this way, if the level of interest of Infant A for each genre (field of study) is displayed on the display unit 22, parent B of Infant A can understand the level of interest of Infant A. In other words, the interest level estimation system 10 can assist parent B in understanding the level of interest of Infant A by providing the level of interest in genres. A parent who is provided with the level of interest in genres that correspond to higher concepts of behavior can more easily set educational guidelines for Infant A than when provided with the level of interest in behavior. For example, comparing being provided with information that Infant A is interested in playing with blocks with being provided with information that Infant A is interested in arithmetic, parent B can more easily set educational guidelines (such as what kind of teaching materials to prepare) in the latter case.

[0082] Furthermore, in the above-described inferring operation 1, the acquiring unit 44 acquires both the schedule information and the performance information, but it is sufficient for the acquiring unit 44 to acquire at least the schedule information. In other words, in the above-described inferring operation 1, where it is described that both the schedule information and the performance information are used, only the schedule information may be used.

[0083] Furthermore, the formula used to estimate the second interest level in the above-described estimation operation 1 is merely an example, and the formula for estimating the second interest level may be appropriately determined empirically or experimentally. Furthermore, a machine learning model may be used to estimate the second interest level. Such a machine learning model receives schedule information and performance information (at least the schedule information) as input and outputs second interest level information. The machine learning model can be constructed using schedule information and performance information (at least the schedule information) as learning data, to which the subjective evaluation results of the interest level for each behavior are assigned as correct answer labels.

[0084] [Estimated Action 2: Estimated Action of Parental Interest Level] Next, a description will be given of an estimating operation 2 for estimating the interest level of guardian B using the behavior information input as described above. Fig. 17 is a flowchart of the estimating operation 2 (the operation for estimating the interest level of guardian B).

[0085] First, the communication unit 41 of the degree of interest estimating device 40 receives behavioral information from the first information terminal 20 (S31), and the information processing unit 42 stores the received behavioral information in the storage unit 43 (S32). The behavioral information is, for example, periodically transmitted from the first information terminal 20 to the degree of interest estimating device 40, but may also be transmitted aperiodically. The behavioral information may be transmitted together with schedule information and performance information, or may be transmitted separately from the schedule information and performance information. The storage unit 43 stores (accumulates) behavioral information for at least a predetermined period, and the level of interest of guardian B is estimated based on the behavioral information for the predetermined period. The predetermined period is, for example, one month, but may also be one week, and is not particularly limited.

[0086] After step S32, the communication unit 41 receives the 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 if the conversion parameter information has already been stored in the storage unit 43, the processing of steps S33 and S34 is omitted.

[0087] Next, the acquisition unit 44 acquires behavioral information for the above-mentioned specified period from the memory unit 43 (S35), and the estimation unit 45 tally up the number of times each of one or more behaviors that parent B wants infant A to engage in during the specified period is selected based on the acquired behavioral information (S36).

[0088] Next, the acquisition unit 44 acquires conversion parameter information from the storage unit 43 (S37), and the estimation unit 45 converts the counting result from step S36 into third interest level information based on the acquired conversion parameter information (S38). That is, the estimation unit 45 estimates guardian B's level of interest in each of a plurality of genres based on the counting result of the number of times the behavior was selected and the acquired conversion parameter information. Fig. 18 is a diagram for explaining a method for converting the counting result into third interest level information.

[0089] The estimation unit 45 multiplies each value in the column of the number of selections in the tabulation result in FIG. 18(a) by each value (coefficient) in the column of "Japanese" in the conversion parameter information in FIG. 18(b), and then sums the resulting multiplications to calculate the third interest level for "Japanese." Similarly, the estimation unit 45 calculates the third interest level for each of "arithmetic," "science," and "social studies," and normalizes the calculated third interest levels. As a result, as shown in FIG. 18(c), third interest level information indicating parent B's third interest level for each of multiple genres is obtained. In other words, the estimation unit 45 can convert the tabulation result into third interest level information (third interest level).

[0090] The output unit 46 outputs the third interest level information obtained in step S38 (S39), and causes the communication unit 41 to transmit the output third interest level information to the second information terminal 30 (S40). The communication unit 35 of the second information terminal 30 receives the third interest level information, and the control unit 33 causes the display unit 32 to display an image indicating the received third interest level information. The image at this time is the same as that shown in FIG. 16 .

[0091] In this way, if the degree of interest of parent B in each genre (field of study) is displayed on the display unit 32, teacher C can grasp the degree of interest of parent B and use it to help in teaching child A. In other words, the interest level estimation system 10 can help teacher C grasp the degree of interest of parent B by providing the degree of interest in genres.

[0092] In step S40, 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 interest level information, and the control unit 23 causes the display unit 22 to display an image indicating the received third interest level information.

[0093] In this way, if the level of interest of parent B in each genre (field of study) is displayed on the display unit 22, parent B can understand his own level of interest.

[0094] In the above-described estimating operation 2, the acquiring unit 44 acquires the behavioral information (planned number of times of behavior), but the acquiring unit 44 may acquire the number of times (actual results) of the behavior selected as the behavioral information in addition to the behavioral information. In this case, the number of times the behavior selected as the behavioral information has been performed is stored in the storage unit 24 of the first information terminal 20, similar to the actual results information, and provided to the interest level estimating device 40.

[0095] Based on the acquired behavioral information, the estimation unit 45 tallies the total number of times each of the one or more behaviors that parent B wants infant A to engage in during a predetermined period of time. That is, the numerical value in the column of the number of times selected in Fig. 18 is the total number of times each of the number of times selected and the number of times performed. When totaling the number of times selected and the number of times performed, a weight may be set for each of the number of times selected and the number of times performed, and the weighted number of times selected and the number of times performed may be totaled.

[0096] [Suggested action] The interest level estimating system 10 can also perform a suggestion operation to suggest an action suitable for infant A based on the interest levels of infant A and guardian B. Fig. 19 is a flowchart of the suggestion operation.

[0097] First, the estimation unit 45 of the interest level estimation device 40 estimates the first interest level of infant A by performing the above-mentioned estimation operation 1 (S51). Specifically, the estimation unit 45 estimates the first interest level of infant A in each of a plurality of genres based on the schedule information acquired by the acquisition unit 44.

[0098] Next, the estimation unit 45 estimates the third interest level of guardian B by performing the above-mentioned estimation operation 2 (S52). Specifically, the estimation unit 45 estimates the third interest level of guardian B for each of a plurality of genres based on the behavior information acquired by the acquisition unit 44.

[0099] Next, the output unit 46 determines actions to be suggested to the infant A and the guardian B based on the estimated first interest level of the infant A and the estimated third interest level of the guardian B (S53).

[0100] Here, the candidate actions to be proposed are the several tens to 50 types of actions (plural actions prepared as options) described above. The above-mentioned conversion parameters are set for these actions. In other words, coefficients indicating the degree of relevance to each of the multiple genres are set for the candidate actions to be proposed.

[0101] The output unit 46 identifies the genre (also referred to as the second genre) with the highest first interest level of infant A estimated in step S51, and identifies the genre (also referred to as the first genre) with the highest third interest level of guardian B estimated in step S52. The output unit 46 determines, from among the candidate behaviors to be suggested, behaviors for which both the coefficient for the first genre and the coefficient for the second genre are greater than predetermined values ​​as behaviors to be suggested (behaviors considered suitable for infant A).

[0102] For example, if the first genre is Japanese and the second genre is arithmetic, actions whose coefficients for Japanese and arithmetic are equal to or greater than a first predetermined value (for example, 4) are determined as actions to be suggested (actions that infant A should take up in the future). If there are multiple applicable actions, all of them may be determined as actions to be suggested, or the action with the largest sum of the coefficient for Japanese and the coefficient for arithmetic may be determined as actions to be suggested, or a random portion of them may be determined as actions to be suggested.

[0103] Furthermore, when the first genre and the second genre are the same, such as when both the first genre and the second genre are Japanese, for example, an action whose coefficient for that genre is equal to or greater than a second predetermined value (for example, 4.5) that is greater than the first predetermined value is determined to be an action to be suggested. In this case, when there are multiple corresponding actions, all of them may be determined to be actions to be suggested, the action with the largest coefficient for that genre may be determined to be an action to be suggested, or a random portion of the actions may be determined to be actions to be suggested.

[0104] Next, the output unit 46 generates proposal information for proposing the action that will be the subject of the proposal 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, for example, a proposal image as shown in Fig. 20 based on the received proposal information. Fig. 20 is a diagram showing an example of the proposal image.

[0105] Furthermore, if the proposed information includes first interest level information obtained as a result of processing in step S51 and third interest level information obtained as a result of processing in step S52, the first interest level information and the third interest level information can also be visualized (graphed) in the proposed image.

[0106] The first interest level information and the third interest level information may be visualized as separate pie charts as in Fig. 16, but in the example of Fig. 20, the first interest level of Infant A for each of a plurality of genres and the third interest level of Parent B for each of a plurality of genres are superimposed on one radar chart. Such a display mode of the first interest level information and the third interest level information allows Teacher C to easily grasp the difference between Infant A's first interest level and Parent B's third interest level.

[0107] In this way, if the behaviors that should be suggested to Child A and Parent B are presented to Teacher C, Teacher C can use this as a reference to set educational guidelines.

[0108] 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 a proposal image based on the received proposal information.

[0109] In this way, if the behavior is directly presented to Infant A and Parent B, Infant A and Parent B can use this as a reference to set educational guidelines.

[0110] A business providing a service using the degree of interest estimating system 10 (degree of interest estimating device 40) may provide the teacher C or the parent B with a report (paper form) corresponding to the proposed image.

[0111] Furthermore, the proposed image only needs to display at least the behavior to be proposed, and it is not necessary for the first interest level information and the third interest level information to be visualized in the proposed image. For example, the output unit 46 can output display information for displaying both the first interest level and the third interest level (information including the contents of both the first interest level information and the third interest level information) separately from the proposed information. That is, the output unit 46 can output information for displaying only the graph portion of the proposed image in FIG. 20 and display only the graph portion on the display unit 22 of the first information terminal 20 or the display unit 32 of the second information terminal 30.

[0112] [Effects, etc.] Hereinafter, examples of inventions that can be obtained from the disclosure of this specification will be given, and the effects and the like that can be obtained from the exemplified inventions will be explained.

[0113] Invention 1 is an interest level estimation system 10 that includes an acquisition unit 44 that acquires behavioral information indicating a first behavior that guardian B of infant A wants infant A to undertake during a target period, the behavioral information being based on a selection operation by guardian B, and schedule information indicating infant A's planned behavior during the target period, the schedule information being based on input operations by at least one of infant A and guardian B; an estimation unit 45 that estimates guardian B's level of interest in each of a plurality of genres related to infant A's behavior based on the acquired behavioral information, and estimates infant A's level of interest in each of the plurality of genres based on the acquired schedule information; and an output unit 46 that outputs suggestion information to suggest an behavior that infant A should undertake based on the estimated levels of interest of guardian B and infant A, wherein the input operation includes an operation to select a second behavior that infant A wishes to perform during the target period, the second behavior being other than the first behavior.

[0114] Such an interest level estimation system 10 can suggest an action that infant A should take by estimating the interest levels of infant A and guardian B. In addition, with a configuration in which the interest level of infant A is estimated based on the selection result of a second action other than the first action that guardian B wants infant A to take, the second action that infant A himself / herself wants rather than that of guardian B is more likely to be selected, resulting in improved accuracy in estimating infant A's interest level.

[0115] Invention 2 is the interest level estimation system 10 described in Invention 1, in which a coefficient indicating the degree of relevance to each of multiple genres is set for the candidate behaviors to be suggested by the suggestion information, and the output unit 46 identifies, from the multiple genres, a first genre in which the estimated guardian B has the highest interest and a second genre in which the estimated child A has the highest interest, and determines, from the candidate behaviors to be suggested, behaviors for which both the coefficient for the first genre and the coefficient for the second genre are greater than predetermined values ​​as behaviors to be suggested by the suggestion information.

[0116] The interest level estimating system 10 can suggest an activity that the infant A should take, based on the genres in which the infant A and the guardian B are highly interested.

[0117] Invention 3 is the interest level estimation system 10 of Invention 1 or 2, in which the output unit 46 further outputs display information for displaying the estimated interest level of guardian B and the estimated interest level of infant A.

[0118] Such an interest level estimating system 10 can display the interest levels of the child A and the parent B, respectively.

[0119] Invention 4 is an interest level estimation system 10 of Invention 3, in which the display information is information for superimposing on a single radar chart the interest level of parent B in each of a plurality of genres and the interest level of child A in each of a plurality of genres.

[0120] Such an interest level estimating system 10 can display the respective interest levels of infant A and parent B in a manner that allows easy relative comparison.

[0121] Invention 5 is an interest level estimation system 10 of any of Inventions 1 to 4, in which the estimation unit 45 tallyes the number of times each of one or more behaviors selected as first behaviors in a predetermined period was selected as a first behavior based on the acquired behavioral information, the acquisition unit 44 further acquires conversion information for converting the tallying results into interest levels for each of a plurality of genres, and the estimation unit 45 estimates parent B's interest level in each of the plurality of genres based on the tallying results and the acquired conversion information.

[0122] Such an interest level estimating system 10 can estimate the interest level of parent B based on the number of times a behavior is selected as the first behavior.

[0123] Invention 6 is an interest level estimation system 10 of any of Inventions 1 to 5, comprising an interest level estimation device 40 including an acquisition unit 44, an estimation unit 45, and an output unit 46, and a first information terminal 20 that communicates with the interest level estimation device 40, wherein the acquisition unit 44 acquires behavioral information based on a selection operation by guardian B on the first information terminal 20, and acquires schedule information based on an input operation by the user on the first information terminal 20.

[0124] Such an interest level estimation system 10 can estimate the interest level of parent B based on behavioral information input to the first information terminal 20, and can estimate the interest level of infant A based on schedule information input to the first information terminal 20.

[0125] Invention 7 is an interest level estimation system 10 described in Invention 5, in which the conversion information is input into the second information terminal 30 by teacher C of the preschool classroom attended by child A, and the acquisition unit 44 acquires the conversion information based on the input operation of teacher C into the second information terminal 30.

[0126] The interest level estimating system 10 can estimate the interest level of the parent B based on the conversion parameter information input by the teacher C.

[0127] Invention 8 is an interest level estimation method executed by a computer such as an interest level estimation system 10. The interest level estimation method includes an acquisition step of acquiring behavioral information indicating a first behavior that guardian B of infant A wants infant A to undertake during a target period, the behavioral information being based on a selection operation of guardian B, and schedule information indicating a schedule of infant A's behavior during the target period, the schedule information being based on an input operation of at least one of infant A and guardian B; an estimation step of estimating guardian B's level of interest in each of multiple genres related to infant A's behavior based on the acquired behavioral information and estimating infant A's level of interest in each of the multiple genres based on the acquired schedule information; and an output step of outputting suggestion information for suggesting an behavior that infant A should undertake based on the estimated degrees of interest of guardian B and infant A, wherein the input operation includes an operation of selecting a second behavior that infant A wishes to perform during the target period, the second behavior being other than the first behavior.

[0128] Such an interest level estimation method can suggest an action that infant A should take by estimating the interest levels of infant A and guardian B. Furthermore, if the configuration is such that infant A's interest level is estimated based on the selection result of a second action other than the first action that guardian B wants infant A to take, infant A's desired second action, rather than guardian B's, is more likely to be selected, resulting in improved accuracy in estimating infant A's interest level.
