The information processing device 2 and the user terminal 3 are configured to be able to communicate with each other via a telecommunications line. In one embodiment, the information processing system 1 is made up of one or more devices or components. For example, if the information processing system 1 is made up of only the information processing device 2, the information processing system 1 can be the information processing device 2. These components will be described below.

[0015] <Information processing device 2> 2 is a block diagram showing a hardware configuration of the information processing device 2. The information processing device 2 includes a communication bus 20, a communication unit 21, a storage unit 22, and a processor 23. The communication unit 21, the storage unit 22, and the processor 23 are electrically connected via the communication bus 20 inside the information processing device 2.

[0016] <Communications Division 21> The communication unit 21 is preferably a wired communication means such as USB, IEEE1394, Thunderbolt (registered trademark), wired LAN network communication, etc., but may also include wireless LAN network communication, mobile communication such as 3G / LTE / 5G, BLUETOOTH (registered trademark) communication, etc. as necessary. In other words, it is more preferable to implement it as a collection of multiple communication means. In other words, the information processing device 2 may communicate various information from the outside via the communication unit 21 and the network.

[0017] <Storage section 22> The storage unit 22 stores various information defined by the above description. This can be implemented, for example, as a storage device such as a solid state drive (SSD) that stores various programs and the like related to the information processing device 2 executed by the processor 23, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to the program calculations. The storage unit 22 stores various programs, variables, etc. related to the information processing device 2 executed by the processor 23.

[0018] <Processor 23> The processor 23 processes and controls the overall operations related to the information processing device 2. The processor 23 is, for example, a central processing unit (CPU) not shown. The processor 23 realizes various functions related to the information processing device 2 by reading out a predetermined program stored in the storage unit 22. That is, information processing by software stored in the storage unit 22 can be specifically realized by the processor 23, which is an example of hardware, and executed as each functional unit included in the processor 23. These will be described in more detail in the next section. The processor 23 is not limited to being single, and may be implemented with multiple processors 23 for each function. Also, a combination of these may be used.

[0019] <User terminal 3> The user terminal 3 is a terminal possessed by a user. In this embodiment, a case will be described in which the user terminal 3 is a terminal operated by a user who undergoes a test regarding cognitive function. The user terminal 3 may be in any form, such as a smartphone, a tablet terminal, a computer, or any other device that can access the information processing device 2 via a telecommunication line.

[0020] 3 is a block diagram showing a hardware configuration of the user terminal 3. The user terminal 3 includes a communication bus 30, a communication unit 31, a storage unit 32, a processor 33, a display unit 34, and an input unit 35. The communication unit 31, the storage unit 32, the processor 33, the display unit 34, and the input unit 35 are electrically connected via the communication bus 30 inside the user terminal 3. Descriptions of the communication unit 31, the storage unit 32, and the processor 33 are omitted because they are similar to the descriptions of the respective units in the information processing device 2.

[0021] <Display section 34> The display unit 34 displays a screen of a graphical user interface (GUI) that can be operated by the user. The display unit 34 may be included in the housing of the user terminal 3, or may be attached externally. Specifically, the display unit 34 may be implemented as a display device such as a CRT display, a liquid crystal display, an organic EL display, or a plasma display. It is preferable that these display devices are implemented by selectively using them according to the type of the user terminal 3.

[0022] <Input section 35> The input unit 35 accepts an operation input made by a user. The operation input is transferred as a command signal to the processor 33 via the communication bus 30. The processor 33 may execute a predetermined control or calculation based on the transferred command signal as necessary. The input unit 35 may be included in the housing of the user terminal 3, or may be externally attached. For example, the input unit 35 may be implemented as a touch panel integrated with the display unit 34. When the input unit 35 is implemented as a touch panel, the user can input a tap operation, a swipe operation, or the like to the input unit 35. As the input unit 35, a switch button, a mouse, a QWERTY keyboard, or the like can be adopted instead of a touch panel.

[0023] 2. Functional configuration In this section, the functional configuration will be described. Fig. 4 is a functional block diagram showing the functions of the information processing device 2. As described above, information processing by software stored in the storage unit 22 can be specifically realized by hardware (specifically, the processor 23) and executed as each functional unit included in the processor 23. In other words, the information processing system 1 includes each functional unit in a program.

[0024] Specifically, the processor 23 includes a reception unit 231, an acquisition unit 232, a calculation unit 233, a specification unit 234, and a display control unit 235 as each functional unit.

[0025] The reception unit 231 is configured to receive various pieces of information as a reception step. Specifically, the reception unit 231 is configured to receive information via the communication unit 21 or the storage unit 22 and to be able to read the information into the working memory. In particular, the reception unit 231 is configured to receive various pieces of information from the user terminal 3 via the network and the communication unit 21.

[0026] The acquiring unit 232 is configured to acquire various pieces of information as an acquiring step. Specifically, the acquiring unit 232 acquires test data IF1 including the results of a test on the cognitive function of the user.

[0027] The calculation unit 233 is configured to execute various information processing calculations as calculation steps, which will be described in detail later.

[0028] The identification unit 234 is configured to identify various pieces of information as an identification step. Specifically, the identification unit 234 identifies a cognitive function level IF2 of the user based on the test data IF1 acquired by the acquisition unit 232. Details will be described later.

[0029] As a display control step, the display control unit 235 displays various pieces of information stored in the storage unit 32 or screens including the same in a manner that is viewable on the user terminal 3. This allows various pieces of information to be presented to various users who operate the user terminal 3. The display control unit 235 controls visual information such as screens, images, icons, and messages to be displayed on the display of the above-mentioned terminal. The display control unit 235 may generate only rendering information for displaying the visual information on the above-mentioned terminal.

[0030] 3. Operation of Information Processing System 1 In this section, with reference to the drawings, a flow of an information processing method executed by the information processing system 1 will be described. As shown below, the information processing method includes the following steps. Note that the order of the processes can be changed as appropriate, multiple processes may be executed simultaneously, and some processes may be omitted.

[0031] 3.1. Overview of information processing FIG. 5 is an activity diagram showing an example of the flow of information processing executed in the information processing system 1. As an example, a case will be described where a user continuously undergoes tests related to cognitive function at a medical institution. The user is, for example, a subject whose cognitive function is to be diagnosed. Note that in this embodiment, the method of diagnosing cognitive function is not particularly limited, and may be, for example, a known method of diagnosing cognitive function by analyzing speech sounds uttered by the subject.

[0032] First, the acquisition unit 232 acquires test data IF1 including the results of a test on the cognitive function of the user as an acquisition step (activity A101). Specifically, for example, the acquisition unit 232 acquires the test data IF1 from a terminal (not shown) owned by a medical professional via the network and the communication unit 21. Here, the test data IF1 may include, for example, a user's answer to a question. Also, the test data IF1 may include, for example, a drawing in which the user copies an arbitrary figure or a housing. Furthermore, the test data IF1 may include a user's answer to a question that tests calculation ability or memory ability.

[0033] Next, the identification unit 234 identifies the user's cognitive function level IF2 based on the acquired test data IF1 as an identification step (activity A102). Here, the user's cognitive function level IF2 is not limited in format, but it is preferable to include, for example, information indicating a stage by numbers. Furthermore, it is preferable that the user's cognitive function level IF2 is associated with a judgment criterion for each level, and the user's symptoms or behavior.

[0034] Independently from the process related to the activity A102, the determination unit 234 determines the ideal level IF3 from the user's age (activity A103). Here, the ideal level IF3 is a cognitive function level determined to be ideal for the user. In this embodiment, the ideal level IF3 is determined from the age as an attribute of the user, but this is not limited thereto. The determination unit 234 may determine the ideal level IF3 based on the user's sex, occupation, medical history, or previous test results. Details will be described later.

[0035] Next, the identification unit 234 identifies a difference between the identified cognitive function level IF2 and the ideal level IF3. Furthermore, as a first display control step (an example of a first presentation step), the display control unit 235 causes the display unit 34 of the user terminal 3 to display visual information that allows the difference between the identified cognitive function level IF2 and the ideal level IF3 to be understood so as to be presentable to the user (activity A104). The visual information will be described in detail later.

[0036] Next, the identification unit 234 identifies whether the difference in cognitive function is equal to or less than a predetermined threshold value (activity A104a) or exceeds (or is equal to or more than) the threshold value. If it exceeds (or is equal to or more than) the threshold value, this means that it has been determined that the user needs detailed examination or treatment, and this process ends. On the other hand, if it is equal to or less than the threshold value, this means that it has been determined that the user does not need full-scale treatment. In this case, the process continues, and the identification unit 234 identifies the next examination date for the user (activity A105). A specific method for identifying the next examination date will be described in detail later.

[0037] Next, the identification unit 234 identifies whether or not the examination date is set within the predetermined number of days (activity A105a). If the examination date is set within the predetermined number of days, that is, when the examination date is within the predetermined number of days from the present, the process proceeds to activity A106. In this case, the display control unit 235 displays a reminder notification regarding the next examination schedule on the display unit 34 of the user terminal 3 (activity A106). In other words, as a second display control step (an example of a second presentation step), the display control unit 235 displays information for encouraging a user whose scheduled examination date is within the predetermined number of days to visit a medical institution on the display unit 34 of the user terminal 3 so as to be presentable to the user. Here, the predetermined number of days is, for example, 1 to 14 days, preferably 1 to 7 days, and specifically, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14 days. The predetermined number of days may be configured to be set by the user. Furthermore, the reminder notification may be sent only once or may be sent two or more times until the scheduled examination date.

[0038] Next, the identification unit 234 identifies whether or not the medical institution has accepted the visit (activity A106a). If the visit has been accepted, this process ends. On the other hand, if the visit has not been accepted (not accepted), the identification unit 234 further identifies whether or not the scheduled examination date has passed (activity A106b). Here, if the scheduled examination date has passed, the display control unit 235 causes the display unit 34 of the user terminal 3 to display a notice encouraging the user to visit the hospital (activity A107). Furthermore, it is preferable that the display control unit 235 repeats the processes related to activities A106a, A106b, and A107 at predetermined intervals until the user's visit is accepted.

[0039] In summary, the information processing method executed by the information processing system 1 includes the following steps. In the acquisition step, test data IF1 including the results of a test on the user's cognitive function is acquired. In the identification step, a cognitive function level IF2 of the user is identified based on the acquired test data IF1. In the first presentation step, visual information that enables the user to grasp the difference between the identified cognitive function level IF2 and an ideal level IF3 is presented to the user. The ideal level IF3 is a cognitive function level determined to be ideal for the user.

[0040] According to this embodiment, the user can grasp the difference between the ideal level IF3, which is the ideal cognitive function level, and the user's current cognitive function level IF2. Therefore, the user can be encouraged to take the test voluntarily. In addition, the user can be encouraged to visit a medical institution when the scheduled test date is approaching. This makes it possible to encourage the user to take the test continuously, enabling early detection and early treatment of cognitive decline.

[0041] 3.2 Details of data processing The above-mentioned information processing will be described in detail with reference to FIGS.

[0042] (User information management table T1) 6 is a schematic diagram of the user information management table T1. The user information management table T1 is a lookup table showing information including user information IF4. Here, the user information IF4 includes information on personal information of a user who is a patient undergoing a cognitive function test.

[0043] For example, the user information management table T1 may include information such as a patient ID T11, a name T12, a date of birth T13, an age T14, a gender T15, an occupation T16, an address T17, a reservation ID T18, and a test result IDT19. In other words, the user information management table T1 includes information on the attributes of the user. The attributes also include age.

[0044] As an example, when a user registers his / her own information in order to undergo examinations continuously, the calculation unit 233 in the information processing device 2 accepts information from the user via the user terminal 3 and updates the information T11 to T17 in the user information management table T1. In addition, when the reception unit 231 accepts a reservation for an examination from the user via the user terminal 3, the calculation unit 233 updates the information of the reservation IDT18 in the user information management table T1. Furthermore, when the acquisition unit 232 acquires the examination data IF1 of the user, the calculation unit 233 updates the information of the examination result IDT19.

[0045] Here, a method for determining the ideal level IF3 in the activity A103 in Fig. 5 will be described with reference to Fig. 8. In this embodiment, an example of determining the ideal level IF3 of a user based on age as an example of a user attribute will be described.

[0046] First, the identification unit 234 in the information processing device 2 identifies the age of the user from the user information management table T1. In this embodiment, the age of the user "Yamada Taro" is "60 years old." Next, the calculation unit 233 extracts the test results IDT19 of other users based on the identified age of the user. Specifically, the calculation unit 233 extracts the test results IDT19 of other users whose age is "60 years old."

[0047] Here, the extraction method is not limited to this. The calculation unit 233 may extract the test results IDT19 of other users whose ages are any of "59 to 61 years old", and further, the calculation unit 233 may extract the test results IDT19 of other users whose ages are any of "60 to 65 years old". Preferably, the calculation unit 233 extracts the test results IDT19 of other users whose ages are close to that of the user.

[0048] Furthermore, the specifying unit 234 specifies an ideal level IF3 of the user "Taro Yamada" based on the extracted test result IDT19. Specifically, for example, the specifying unit 234 may specify the ideal level IF3 based on an average value of the test data IF1 related to the extracted test result IDT19.

[0049] In the present embodiment, age has been described as an example of an attribute, but this is not limiting. For example, the specification unit 234 may specify the ideal level IF3 for the user based on at least one of the following attributes: gender, occupation, and medical history.

[0050] In summary, the specification unit 234 further specifies the ideal level IF3 together with the cognitive function level IF2 based on the user information management table T1, which is a preset database. Furthermore, the database, which is the user information management table T1, is configured to associate and manage the user attributes and at least one piece of test data IF1 for each user.

[0051] According to this embodiment, the user can understand his / her own position in terms of cognitive function based on his / her attributes (occupation, sex, age, etc.). In addition, an appropriate ideal level IF3 can be set for each user based on the user's attributes.

[0052] (Reminder screen 5) Fig. 7 shows an example of a reminder screen 5 displayed on the display unit 34 of the user terminal 3 to remind the user of the appointment date of the examination. The reminder screen 5 is an example of a screen displayed in activity A106 of Fig. 5. The reminder screen 5 includes areas 51, 52, 53, 54, 55, and an operation button 56. In this embodiment, a case will be described where the user makes an appointment for the next examination in activity A105 of Fig. 5.

[0053] Area 51 is an area where a notification is displayed to inform the user that the next scheduled examination date is approaching. Areas 52 and 53 are areas where the details of the medical appointment are displayed. For example, area 52 is an area where an appointment ID is displayed. Area 53 is an area where the user's appointment date and time, medical institution, and department are displayed. In other words, area 53 is an area where appointment information corresponding to the appointment ID displayed in area 52 is displayed.

[0054] Areas 54 and 55 are areas where information related to personal information of a user who is a patient is displayed. For example, area 54 is an area where a patient ID is displayed. Area 55 is an area where a user's name, sex, and date of birth are displayed. In other words, area 55 is an area where user information IF4 corresponding to the patient ID displayed in area 54 is displayed. The appointment ID is associated with user information IF4 and stored in user information management table T1 in FIG. 6.

[0055] The operation button 56 is a button for accepting a request to cancel or change the reservation displayed on the remind screen 5. For example, by accepting an input to the operation button 56 from the user, the display control unit 235 transitions the content displayed on the display unit 34 of the user terminal 3 from the remind screen 5 in Fig. 7 to a screen (not shown) for accepting a request to cancel or change the reservation.

[0056] According to this aspect, it is possible to prompt a user who is approaching a scheduled examination date to visit a medical institution, thereby realizing early detection and early treatment, which are considered to be important in preventing dementia.

[0057] (Notification screen 6 encouraging patients to visit the hospital) Fig. 8 shows an example of a notification screen 6 for encouraging a visit to a hospital, which is displayed on the display unit 34 of the user terminal 3. The notification screen 6 for encouraging a visit to a hospital is an example of a screen displayed in activity A107 of Fig. 5. The notification screen 6 for encouraging a visit to a hospital has an area 61, an area 62, an area 63, an area 64, a second character Ca, and an operation button 65.

[0058] Area 61 is an area where a notification is displayed to the user that the scheduled examination date has passed. Areas 62 and 63 are areas where the details of the medical appointment are displayed. The explanation of areas 52 and 53 in FIG. 6 is the same as that of areas 52 and 53, so it will be omitted.

[0059] Furthermore, the display control unit 235 displays a second character Ca. The second character Ca has an appearance display imitating the appearance of a user in a state of cognitive decline, for example. That is, the second character Ca has an appearance display imitating a change in the user himself that may occur if the user does not undergo regular examinations and is unable to detect cognitive decline early. In other words, as a third display control step (an example of a third presentation step), the display control unit 235 presents the second character Ca to a user who has exceeded the scheduled date, by changing the second character Ca in a manner according to the number of days exceeded. Specifically, the display control unit 235 changes the character in a manner that indicates that the greater the number of days exceeded from the scheduled date, the greater the need to visit a medical institution.

[0060] 8, the second character Ca is a character that is displayed when the user is one week past the scheduled examination date. If the user has not visited a medical institution even though one month has passed since the scheduled examination date, the display control unit 235 may display a character that indicates a state in which the cognitive function is further deteriorated than that of the second character Ca.

[0061] Moreover, area 64 is an area for displaying a message to the user encouraging the user to make an appointment at a medical institution. Furthermore, operation button 65 is a button for accepting a change to the appointment displayed on notification screen 6 encouraging the user to visit a hospital. For example, by accepting an input to operation button 65 from the user, display control unit 235 transitions the content displayed on display unit 34 of user terminal 3 from notification screen 6 encouraging the user to visit a hospital in FIG. 8 to a screen (not shown) for accepting a change to the appointment.

[0062] According to this embodiment, the user can be made more aware of the need to visit a medical institution, and furthermore, the user can be encouraged to undergo an examination.

[0063] (Result display screen 7) 9 shows an example of the result display screen 7 displayed on the display unit 34 of the user terminal 3. The result display screen 7 is an example of a screen displayed in the activity A104 of FIG. 5. The result display screen 7 has an area 71, an area 72, a graph 73, a user character Cb, a first character Cc, and an operation button 74. In this embodiment, a case where the cognitive function level IF2 of the user is specified by an index of brain age will be described. Also, a case where the ideal level IF3 of the user is specified based on age will be described.

[0064] The display control unit 235 causes the user character Cb to be displayed on the display unit 34. The user character Cb has an appearance display that imitates, for example, the user's current appearance. The appearance that imitates the user's current appearance may be determined, for example, according to the user's age. In this embodiment, the user character Cb that corresponds to the age "60 years old" of the user "Yamada Taro" is displayed on the display unit 34.

[0065] Area 71 is an area where information indicating the user's cognitive function level IF2 is displayed. In this embodiment, the brain age indicating the user's cognitive function level IF2 is "65 years old." This indicates that the user's cognitive function level IF2 is approximately the same as the average value of the cognitive function levels IF2 of other users who are 65 years old.

[0066] Area 72 is an area where information is displayed that allows the user to grasp the difference between the cognitive function level IF2 and the ideal level IF3. In this embodiment, the user's ideal level IF3 is a level equivalent to the average value of cognitive function data for patients with the user's age of "60 years old". In other words, in this embodiment, the difference between the user's ideal level IF3 and the cognitive function level IF2 is equivalent to 5 years in age. In other words, the result display screen 7 shows that the cognitive function level IF2 of user "Yamada Taro" has declined early, equivalent to 5 years, compared to the average.

[0067] Furthermore, visual information that allows the user's cognitive function level IF2 to be understood is displayed on the result display screen 7. For example, a first character Cc is displayed on the display unit 34 as visual information. In other words, the visual information includes the first character Cc. Furthermore, the display control unit 235 presents the first character Cc to the user in a manner corresponding to the cognitive function level IF2 as a first display control step (an example of a first presentation step). In this embodiment, the first character Cc may be displayed as, for example, a character in a manner corresponding to a brain age "equivalent to 65 years old", which is the user's cognitive function level IF2.

[0068] Furthermore, in this embodiment, the display control unit 235 displays a user character Cb corresponding to the user's age "60 years old" and a first character Cc corresponding to the user's cognitive function level IF2 "equivalent to 65 years old" on the same screen in a comparable manner. The user can understand that his / her own cognitive function level IF2 is declining relative to his / her age (i.e., his / her cognitive function is ranked relatively low among those of the same age group).

[0069] That is, the greater the difference between the user's cognitive function level and the ideal level IF3, the greater the difference in age between the user character Cb and the first character Cc is displayed. In other words, the visual information includes the first character Cc. As a first display control step (an example of a first presentation step), the display control unit 235 presents the first character Cc to the user in a manner according to the difference. According to this manner, the greater the difference between the cognitive function level IF2 and the ideal, the more the user can be made to recognize the importance of early detection and early treatment. Thus, the user can be encouraged to voluntarily undergo testing.

[0070] Furthermore, it is preferable that the result display screen 7 includes a graph 73 as information showing changes in the user's cognitive function level IF2. The graph 73 has an axis 73x indicating time on the horizontal axis and an axis 73y indicating brain age on the vertical axis. The display control unit 235 displays information showing changes in the user's cognitive function in a form in which brain age (an example of the cognitive function level IF2) is plotted for each timing at which the user underwent a test. This allows the user to understand changes in his or her own cognitive function level IF2. Therefore, it is possible to encourage the user to voluntarily undergo a test. 4. Second embodiment

[0071] In this section, an information processing system 1 according to a second embodiment (hereinafter, referred to as this embodiment) will be described. However, descriptions of configurations and functions that are substantially similar to those of the information processing system 1 according to the first embodiment will be omitted. The figures newly referred to in this section are as follows.

[0072] (Reservation reminder screen 8) Fig. 10 shows an example of an appointment reminder screen 8 displayed on the display unit 34 of the user terminal 3. The appointment reminder screen 8 is an example of a screen displayed in activity A106 in Fig. 5. This embodiment differs from the first embodiment in that a reminder is issued to encourage the user to make an appointment for an examination when the time when it is preferable to take the examination approaches.

[0073] The appointment reminder screen 8 has an area 81, an area 82, an area 83, and an operation button 84.

[0074] The area 81 is an area where the arrival of the time for the user to undergo an examination is displayed. The determination unit 234 may determine the next examination timing based on the timing of the last examination taken by the user. For example, the determination unit 234 may determine the next examination timing by adding a predetermined period (for example, 1 to 6 months) to the timing of the last examination taken by the user.

[0075] Areas 82 and 83 are areas where user information IF4 is displayed, and the explanation thereof is the same as that of areas 54 and 55 in FIG. 7 and therefore will be omitted.

[0076] The operation button 84 is a button for making a reservation at a medical institution. For example, the operation button 84 may be a button for searching for a medical institution that can accept a reservation. As an example, the display control unit 235 receives an input to the operation button 84 from the user, and transitions the content displayed on the display unit 34 of the user terminal 3 from the appointment reminder screen 8 in FIG. 10 to a medical institution presentation screen 9 in FIG. 11.

[0077] (Medical institution display screen 9) 11 shows an example of a presentation screen 9 of a medical institution displayed on the display unit 34 of the user terminal 3. The presentation screen 9 of a medical institution has an area 91, an area 92, an area 93, an operation button 94, an area 95, and an operation button 96.

[0078] The area 91 is an area where a notification indicating medical institutions recommended to the user is displayed. The area 92 is an area where a map generated based on the medical institutions recommended to the user and the position information related to the user's home is displayed. The area 92 includes a home icon 921 and medical institution icons 922 and 923.

[0079] The home icon 921 is displayed at a position corresponding to the location information related to the user's home, i.e., the address of the home. The medical institution icons 922 and 923 are displayed at positions corresponding to the location information related to each medical institution, i.e., the address of the medical institution. In other words, the display control unit 235 presents to the user, as a fourth display control step (an example of a fourth presentation step), information indicating a medical institution where the user can undergo an examination. Here, the medical institution is an institution determined based on the user's personal information (user information IF4). According to this aspect, the user can know medical institutions where the user can undergo an examination. Therefore, the user can be encouraged to undergo an examination.

[0080] Here, the medical institution recommended to the user (hereinafter, referred to as the recommended medical institution) may be specified as follows. For example, the specification unit 234 may preferentially specify, as the recommended medical institution, a medical institution within a predetermined distance from the user's address among medical institutions at which a reservation for an examination can be made. Also, for example, the specification unit 234 may preferentially specify, as the recommended medical institution, a medical institution that is the user's regular doctor or a medical institution that is affiliated with the user's regular doctor among medical institutions at which a reservation can be made. Furthermore, the specification unit 234 may preferentially specify, as the recommended medical institution, a medical institution that the user has visited in the past among medical institutions at which a reservation can be made. The specification unit 234 may specify, as the recommended medical institution, a medical institution at which the user has visited in the past among medical institutions at which a reservation can be made. The specification unit 234 may specify the recommended medical institution based on at least one of the above conditions.

[0081] Furthermore, areas 93 and 95 are areas for displaying information about the recommended medical institution displayed in area 92. In this embodiment, information about the medical institution corresponding to medical institution icon 922 is displayed in area 93. Furthermore, information about the medical institution corresponding to medical institution icon 923 is displayed in area 95. The display control unit 235 may display information about the medical institutions in descending order of priority as recommended medical institutions.

[0082] Furthermore, operation button 94 is a button for reserving an examination at a medical institution displayed in area 93. Similarly, operation button 96 is a button for reserving an examination at a medical institution displayed in area 95. As an example, by accepting an input to operation button 94 or 96 from the user, the display control unit 235 transitions the content displayed on the display unit 34 of the user terminal 3 from the medical institution presentation screen 9 in FIG. 11 to a screen (not shown) for accepting a reservation from the user at the medical institution corresponding to operation button 94 or 96.

[0083] According to this embodiment, the user can be prompted to make a reservation for a test. Therefore, the user can be further encouraged to voluntarily take a test.

[0084] 5. Variations The above information processing mode is merely an example and is not limited to this.

[0085] 5, the acquiring unit 232 acquires the user's examination data IF1 from a terminal (not shown) owned by a medical professional, but the example is not limited to this. The acquiring unit 232 may acquire the user's examination data IF1 directly from various medical devices (not shown), for example.

[0086] 5, the specification unit 234 specifies the ideal level IF3 based on the age of the user, but the present invention is not limited to this. The ideal level IF3 may be uniquely determined.

[0087] In the activity A104 of FIG. 5, the display control unit 235 may further display the difference in cognitive function in a manner that is visible from the facial expression of the character. For example, when the brain age is high relative to the actual age of the user, the display control unit 235 may display the user character Cb or the first character Cc with an anxious expression on the display unit 34. In addition, the user character Cb or the first character Cc may be displayed on the display unit 34 in a manner that the degree of anxious expression increases as the brain age is high relative to the actual age of the user and the difference is large. On the other hand, when the brain age is low relative to the actual age of the user, the display control unit 235 may display the user character Cb or the first character Cc with a smiling expression on the display unit 34. According to such a manner, the user can easily grasp his / her own cognitive function level IF2. Furthermore, the user can be further encouraged to voluntarily undergo a test.

[0088] 5, the display control unit 235 may also notify a reminder or the like to a terminal (not shown) operated by the user's family member. This allows the family member to know the timing to take the test, further encouraging the user to take the test.

[0089] In the activity A106 in Fig. 5, the method of specifying the timing to take the test or the timing to reserve the test by the specifying unit 234 is not limited to this. The timing to take the test or the timing to reserve the test may be determined further based on the timing and test result of the last test taken by the user. Specifically, when the test result shows a decline in cognitive function, the timing of the next test may be determined by adding a period slightly shorter than a predetermined period (for example, 1 to 6 months) to the timing of the last test taken.

[0090] The identification unit 234 may further determine the timing of the examination according to the change in the user's environment. For example, for a user whose environment has changed due to retirement or the like, the timing of the examination may be determined so that the period between examinations is short within a predetermined period (for example, within about six months to three years) from the time when the environment changed. This allows early detection of a decline in cognitive function caused by the change in the user's environment. The acquisition unit 232 may receive information on the change in environment from the user and store the information in the user information management table T1 as user information IF4.

[0091] Furthermore, the identification unit 234 may determine the timing to take the test or schedule the test based on the user's own attributes (age, sex, occupation, medical history, etc.), or may determine the timing by combining at least one of the attributes mentioned above.

[0092] 9, the display control unit 235 may display information related to prevention of cognitive decline in accordance with the test results related to the user's cognitive function. For example, the display control unit 235 may transition to a screen for viewing information related to prevention of cognitive decline by accepting an input from the user to an operation button (not shown). According to this embodiment, it is possible to encourage the user to voluntarily prevent cognitive decline.

[0093] In the above embodiment, the information processing device 2 performs various storage and control, but multiple external devices may be used instead of the information processing device 2. That is, various information and programs may be distributed and stored in multiple external devices using block chain technology or the like.

[0094] At least one of the devices included in the information processing system 1 may be installed outside Japan. For example, the information processing device 2 may be installed outside Japan, and each terminal device may be installed inside Japan. Similarly, a user may access the information processing device 2 installed inside Japan from outside Japan using his / her own terminal. According to such an embodiment, a more convenient experience can be provided to the user through various management forms.

[0095] Another aspect of the embodiment may be a program. The program causes at least one computer to execute each step in the information processing system 1. According to this aspect, the user can understand the difference between the actual cognitive function level and the ideal cognitive function level. Therefore, the user can be encouraged to take the test voluntarily.
