[0012] In one embodiment, a "unit" may include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In one embodiment, various information is handled, and this information is represented, for example, by physical values ​​of signal values ​​representing voltage and current, high and low signal values ​​as a binary bit set consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculations can be performed on a circuit in the broad sense.

[0013] Furthermore, a circuit in the broad sense is a circuit realized by at least an appropriate combination of a circuit, circuitry, processor, memory, etc. The processor may be a general-purpose processor or a dedicated circuit. That is, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0014] [Embodiment] 1. Hardware Configuration This section explains the hardware configuration.

[0015] 1.1 Information Processing System 1 FIG. 1 is a configuration diagram illustrating an information processing system 1. The information processing system 1 includes an information processing device 2, a user terminal 3, and a sound collection device 4. The information processing device 2, the user terminal 3, and the sound collection device 4 are configured to be able to communicate with each other via a telecommunications line. In one embodiment, the information processing system 1 includes one or more devices or components. For example, if the information processing system 1 includes only the information processing device 2, the information processing system 1 can be the information processing device 2. More specifically, the information processing system 1 may include an element selected from the group consisting of the information processing device 2, the user terminal 3, and the sound collection device 4. Furthermore, multiple information processing devices 2, user terminals 3, or sound collection devices 4 may be used. The elements not selected may not be included in the information processing system 1, but may be electrically connected to the selected elements as external elements. These components will be described below.

[0016] 1.2 Information processing device 2 2 is a block diagram showing the 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.

[0017] 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 needed. 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.

[0018] The storage unit 22 stores various pieces of information defined above. This may be implemented as a storage device such as a solid state drive (SSD), a solid state hybrid drive (SSHD), a hard disk drive (HDD), a universal serial bus (USB) flash drive (USB memory), an SD memory card, a CD, a DVD, or a Blu-ray (registered trademark) disc (BD) 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 program calculations. The storage unit 22 stores various programs, variables, etc. related to the information processing device 2 executed by the processor 23.

[0019] 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 predetermined programs stored in the storage unit 22. In other words, information processing by software stored in the storage unit 22 is specifically realized by the processor 23, which is an example of hardware, and can be executed as each functional unit included in the processor 23. These will be described in more detail in the next section. Note that the processor 23 is not limited to being single, and multiple processors 23 may be provided for each function. A combination of these may also be used.

[0020] 1.3 User terminal 3 The user terminal 3 is a terminal carried by a user. The user terminal 3 may be a terminal operated by a medical professional (hereinafter also referred to as a medical professional) such as a doctor, nurse, or elderly care facility employee, or may be a terminal operated by a user (subject) whose cognitive function is to be evaluated. The user terminal 3 may be in any form, such as a smartphone, tablet, computer, or other device that can access the information processing device 2 via a telecommunications line. Note that cognitive function does not only refer to dementia (mild, moderate, or severe), but also includes mild cognitive impairment (a precursor to mild dementia).

[0021] 3 is a block diagram showing the hardware configuration of the user terminal 3. The following description will be given taking the user terminal 3 as an example. 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. The description of the communication unit 31, the storage unit 32, and the processor 33 will be omitted as they are the same as the description of each unit in the information processing device 2.

[0022] 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 externally attached. 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 depending on the type of the user terminal 3.

[0023] The input unit 35 accepts operation inputs made by a medical professional or a subject. The operation inputs are transferred as command signals to the processor 33 via the communication bus 30. The processor 33 can execute predetermined control or calculations based on the transferred command signals as necessary. The input unit 35 may be included in the housing of the user terminal 3 or may be attached externally. 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 medical professional or user can input tap operations, swipe operations, etc. to the input unit 35. Instead of a touch panel, a switch button, a mouse, a QWERTY keyboard, etc. can be used as the input unit 35.

[0024] 1.4 Sound collection device 4 The sound collection device 4 is a so-called microphone that is configured to be able to convert external sounds into signals. The sound collection device 4 may be provided by directly connecting the sound collection device 4 to the information processing device 2, but is provided in or connected to the user terminal 3.

[0025] The sound collection device 4 is configured to generate voice data by collecting the user's speech. The voice data is temporarily stored in a memory in the user terminal and does not have to be stored non-volatilely in the storage unit 32. The voice data generated by the sound collection device 4 is configured to be transferable to the information processing device 2 via a network.

[0026] The sound collection device 4 collects, but is not limited to, at least sounds in the human audible range, sounds with frequencies between 20 Hz and 20,000 Hz, and converts them into electrical signals. The sound may be recorded in monaural or stereo. The sampling rate for digitally processing the sound data may be, for example, 48,000 Hz, 44,100 Hz, 32,000 Hz, 22,050 Hz, 16,000 Hz, 11,025 Hz, 11,000 Hz, 8,000 Hz, etc. The sampling rate may be within any of the ranges of values ​​exemplified here. Increasing the sampling rate allows for more precise discretization of the temporal timing of the sound, improving the accuracy of voice recognition.

[0027] Furthermore, the data collected by the sound collection device 4 may be appropriately compressed by the processor 33 of the user terminal 3, and the compression format at this time may be any of MP3, AAC, WMA, Vorbis, AC3, MP2, FLAC, TAK, etc. Compression can reduce communication traffic due to data transfer from the user terminal to the information processing device 2.

[0028] 2. Functional configuration In this section, the functional configuration will be described. Fig. 4 is a functional block diagram showing the functions of the processor 23 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 has each functional unit in a program.

[0029] Specifically, the processor 23 includes a receiving unit 231, an acquiring unit 232, an identifying unit 233, an evaluating unit 234, and a presenting unit 235 as its functional units.

[0030] The reception unit 231 is configured to receive various types of information. The various types of information received by the reception unit 231 include, for example, basic information d1, voice information d2, information d3 related to the subject's daily life, and information d4 related to medical treatment received by the subject. The reception unit 231 is configured to receive this information via, for example, the communication unit 21 or the storage unit 22, and to read this information into a working memory. In one example of an embodiment, the reception unit 231 receives input of voice information d2 related to a speech voice from the subject via the sound collection device 4.

[0031] The acquisition unit 232 is configured to acquire various information. Here, the acquisition function of the acquisition unit 232 may be a function to receive similar information only, a function to generate desired information by performing various processes on the received data only, or both of these functions. The acquisition unit 232 includes a life information acquisition unit 232a and a test information acquisition unit 232b. In an example of an embodiment, the life information acquisition unit 232a is configured to acquire life information d31 based on the information accepted by the acceptance unit 231, and the test information acquisition unit 232b is configured to acquire test information d21 based on the information accepted by the acceptance unit 231.

[0032] The specifying unit 233 is configured to specify various pieces of information. Specifically, the specifying unit 233 specifies a presentation mode for instructions to prompt the subject to speak, based on the user information acquired by the acquiring unit 232.

[0033] The evaluation unit 234 is configured to evaluate various characteristics. Preferably, the evaluation unit 234 generates consultation recommendation information drm for recommending that the subject (user) visit a medical institution, based on the lifestyle information d31 and the examination information d21 acquired by the acquisition unit 232 and predetermined reference information dref.

[0034] The presentation unit 235 presents various pieces of information stored in the memory unit 32 in a manner that can be understood by the presentation target. The presentation target may be, for example, a subject, the subject's family, or a medical professional. The subject's family may include not only the subject's family, but also relatives and those in a position to protect and support the subject (e.g., adult guardians). For example, the presentation unit 235 may display a screen or the like containing various pieces of information in a visible manner on various terminals, such as the user terminal 3. This presents various pieces of information to those operating various terminals, such as the user terminal 3. The presentation unit 235 preferably controls the display of visual information, such as screens, images, icons, and messages, on the displays of the various terminals described above. The presentation unit 235 may generate only rendering information for displaying visual information on the terminals. The presentation unit 235 may also present various pieces of information to the presentation target as auditory information. Furthermore, the presentation unit 235 may present various pieces of information to the subject as texture information (Braille information) that provides a textured feel to the fingers. In this case, the display is preferably compatible with Braille.

The test results of the test information d21 are level information indicating the degree of the subject's cognitive function, and the form is not particularly limited, and may be expressed, for example, as numbers or may be indicated as high, medium, or low. Note that the diagnosis of cognitive function is not limited to fixed utterances (such as standard phrases) and may be combined with various speech formats. Furthermore, it may be further combined with various evaluation methods such as fluctuations in foot and hip movements during walking and eye movements. Other known diagnostic methods may also be used.

[0041] The lifestyle information d31 is information about the lifestyle of the user (subject) and can be acquired based on the above-described information d3. The lifestyle information d31 has content adjusted to make the above-described information d3 easier to process, but the lifestyle information d31 does not necessarily need to be distinguished from this information d3 and may have the same content. In other words, the information d3 itself may be the lifestyle information d31. The lifestyle information d31 includes pattern information related to the user's daily lifestyle patterns and risky behavior information related to the user's preferences or unintentional behavior.

[0042] Here, the pattern information includes at least one of mealtime information, walking information, tooth brushing information, bathing information, sleep information, exercise content information, GPS information, water heater usage information, and medication information.

[0043] Mealtime information may include at least one piece of information such as the time a meal is started and finished.

[0044] The risk behavior information includes at least one of drinking information, smoking information, video viewing status information, sleep respiration information, and fall information.

[0045] The drinking information may include at least one of information such as the number of times (frequency) a person drinks alcohol in a predetermined period and the amount of alcohol consumed in the predetermined period. The smoking information may include at least one of information such as the number of times (frequency) a person smokes alcohol in a predetermined period and the amount of alcohol consumed in the predetermined period. The video viewing status information may include at least one of information such as the number of times (frequency) a person watches videos in a predetermined period and the total video viewing time in the predetermined period. The sleep breathing information may include at least one of information such as information regarding snoring, information indicating a sleep apnea state, or information regarding changes in heart rate during sleep. The fall information may include information indicating the number of times the subject has fallen. The fall information may be, for example, a part that detects falls from impacts associated with an electronic wristwatch.

[0046] The consultation recommendation information drm is information acquired based on the test information d21, lifestyle information d31, and predetermined reference information dref. The consultation recommendation information drm is information for recommending that the user (subject) visit a medical institution. The medical institution is preferably a field that specializes in examining people with reduced cognitive function, such as psychiatry, neurology, or geriatrics. The consultation recommendation information drm can be expressed as information encouraging the subject to visit a medical institution, or as information indicating that there is no need for the subject to visit a medical institution.

[0047] The predetermined reference information dref is information for associating the examination information d21 and the lifestyle information d31 with whether or not to encourage a patient to undergo medical examination. Details of this reference information dref will be described later.

[0048] 3.2 Overview of Information Processing An overview of information processing will be described with reference to Figures 5 and 6. The information processing system 1 is configured to be able to execute each activity related to the information processing method described below. That is, the information processing system 1 includes at least one processor 33, and the processor 33 is configured to execute each step corresponding to the activity by reading a program. In other words, the program used in the information processing system 1 causes the computer (processor 33) to execute each step in the information processing system, and the information processing method in the information processing system 1 includes each step corresponding to the activity in the information processing system 1. The order of the processes can be changed as appropriate, and multiple processes may be executed simultaneously, or some processes may be omitted.

[0049] (Activity A001: Acceptance of various information such as basic information d1) The receiving unit 231 receives basic information d1 (such as the subject's personal ID). When the receiving unit 231 receives the basic information d1, the information processing system 1 can authenticate the subject. The receiving unit 231 also receives information d3 relating to the subject's daily life. When the receiving unit 231 receives this information, it is stored in the memory unit 22. The receiving unit 231 can receive this information from the user terminal 3, for example, via the communication unit 31.

[0050] (Activity A002: Acquiring lifestyle information d31) The acquiring unit 232 (life information acquiring unit 232a) acquires life information d31 using the information d3. This activity A002 is an example of a first acquisition step.

[0051] (Activity A003: Present voice input instructions) The identification unit 233 identifies a presentation mode of instructions to prompt the subject to speak, and presents instructions for voice input based on the identified content. Preferably, the identification unit 233 identifies the presentation mode based on information received in activity A001 or activity A003. The presentation mode is, for example, whether the instructions are presented to the subject as visual information (see, for example, FIG. 7), and there are various methods for the presentation mode, and variations will be described in detail later.

[0052] (Activity A004: Accept voice input) The receiving unit 231 receives the voice information d2. That is, the subject speaks after confirming the instructions in activity A003. The subject's spoken voice (voice information d2) is acquired by the user terminal 3 via the sound collection device 4, and the receiving unit 231 receives the voice information d2 via the user terminal 3.

[0053] (Activity A005: Get inspection information d21) The acquisition unit 232 (test information acquisition unit 232b) acquires (generates) test information d21 based on the voice information d2 and a preset trained model. In other words, the information processing system 1 has a function of testing the level of cognitive function of a certain subject by analyzing the subject's speech. Here, the trained model is a model that has been trained in advance to determine the relationship between the features of a predetermined speech and the level of cognitive function. Details will be described later. This activity A005 is an example of a second acquisition step.

[0054] (Activity A006: Generate consultation recommendation information DRM) The evaluation unit 234 generates consultation recommendation information drm based on the test information d21, the lifestyle information d31, and predetermined reference information dref. The test information d21 used is obtained in activity A005, and the lifestyle information d31 used is obtained in activity A002. The predetermined reference information dref is stored in the storage unit 22.

[0055] (Activities A007, A008: Presentation of results) In activity A007, the presentation unit 235 presents (notifies) the test information d21 and the consultation recommendation information drm to the subject. Note that, although the embodiment has been described assuming that the test information d21 is also presented, it is optional whether or not to present the test information d21. The presentation may be in the form of visual information presented using the display unit 34 of the user terminal 3, auditory information presented using the speaker of the user terminal 3, or Braille, or a combination of these.

[0056] Furthermore, if the consultation recommendation information drm is content that recommends a consultation, in activity A008, the presentation unit 235 transmits this consultation recommendation information drm to a presentation target other than the subject. As a result, the consultation recommendation information drm is also presented (notified) to the presentation target. In this presentation, the consultation recommendation information drm is notified (presented) to a registered terminal that has been registered in advance. For example, the notification can be made by email to an email address of the presentation target that has been pre-registered in the storage unit 22 of the information processing device 2. Alternatively, the notification may be made via various communication applications that allow mutual message exchange. Activities A007 and A008 are examples of a notification step.

[0057] In the embodiment, if the consultation recommendation information drm does not recommend consultation, in activity A008, the presentation unit 235 does not send this consultation recommendation information drm to anyone other than the subject, but this is not limited to this, and the information may also be sent to reassure family members, etc.

[0058] In this way, in activities A007 and A008, based on the lifestyle information d31, the test information d21, and the predetermined reference information dref, the user (subject) is notified (presented) with consultation recommendation information drm for recommending that the user (subject) visit a medical institution. According to this aspect, it is possible to prevent impairment of daily life caused by cognitive function. Specifically, it is possible to encourage the user (subject) to visit a medical institution in advance before their condition worsens, which can be useful for the health of the user (subject).

[0059] 3.3 Details of information processing The above-mentioned information processing will be described in detail with reference to FIGS.

[0060] (Details of Activity A002) The acquisition process of the acquisition unit 232 may include, for example, the following. For example, if the information d3 is a sleep log, it may include a process of analyzing the log to calculate the total sleep time, a process of calculating the total time of deep sleep (light sleep), etc. In other words, the acquisition process may include a process (preprocessing) of adjusting (e.g., changing, selecting, organizing, etc.) the information d3 into information necessary for the evaluation unit 234 of the information processing system 1 to assess cognitive function. In other words, the lifestyle information d31 may not be the same as the information d3, but may be acquired (calculated) from the information d3 through predetermined processing.

[0061] Note that "changing" may include processing such as analyzing certain information to obtain information with different content, "selecting" may include processing such as deleting unnecessary information and extracting necessary information, and "organizing" may include processing such as changing the order of multiple pieces of information.

[0062] On the other hand, the lifestyle information d31 may be the same as the information d3. For example, it is possible that the subject does not have an electronic device that measures the subject's bathing status. In this case, the subject may input their self-reported bathing time as information d3, and this information may be used as the lifestyle information d31. Here, the bathing aspect of the information d3 has been described, but this can also be applied to other aspects such as meals.

[0063] (Details of Activity A003) The specifying unit 233 specifies a presentation mode of the instruction to prompt the subject to speak. Here, the specifying unit 233 can specify the presentation mode based on information received in activity A001 or activity A003.

[0064] For example, the specification unit 233 can specify (determine) the user's age based on the user's age. For example, when the specification unit 233 specifies that the user's age in the basic information d1 is higher than a predetermined threshold, the specification unit 233 may present instructions using both visual information and auditory information, or may adjust the volume of the auditory information or the size of the characters in the visual information. Furthermore, for example, when the specification unit 233 specifies that the basic information d1 includes information about a visual impairment, the specification unit 233 may specify (determine) auditory information as the presentation mode, and conversely, when the specification unit 233 specifies that the basic information d1 includes information about a hearing impairment, the specification unit 233 may specify (determine) visual information as the presentation mode.

[0065] Here, an example will be described in which only visual information is presented. Fig. 7 shows an example of a screen 5 that is displayed on the display unit 34 of the user terminal 3, and is displayed when making an evaluation regarding the recommendation to visit a medical institution.

[0066] As shown in FIG. 7, when receiving voice information d2 from the subject, screen 5 is displayed on the display unit 34 of the user terminal 3. Area 51 displays an instruction to the subject: "Please pronounce the katakana as quickly as possible." Area 52 is an area (object) that receives selection input from the subject. When a selection operation is performed in area 52 (for example, by clicking or tapping area 62), the screen transitions to recording screen 6 shown in FIG. 9. When screen 5 shown in FIG. 7 is displayed, the subject can understand that recording (reception) of voice information d2 will be carried out, which will be used to determine the level of cognitive function and whether or not the subject needs to see a medical institution.

[0067] Figure 8 shows an example of a presentation mode different from screen 5 shown in Figure 7, where Figure 8A shows area 51 positioned in its initial position, and Figure 8B shows area 51 shown in Figure 8A having moved in the direction of arrow Ar shown in Figure 8A.

[0068] Although FIG. 7 illustrates an example in which the screen 5 is a still image, a certain area may move as shown in FIG. 8. A person with a visual impairment such as glaucoma or cataracts may experience visual field defects. For example, in a person with such visual impairment, the character "katama" may appear as "ka ma," and the character "ta" may be invisible (see FIG. 8A). Therefore, when the identification unit 233 identifies that the basic information d1 includes information on visual field defects such as glaucoma or cataracts, it is preferable to move at least a portion of the area displayed on the screen 5, as shown in FIGS. 8A and 8B. As a result, the instruction text moves, and the previously invisible character "ta" moves to an area without visual field defects. As a result, the instruction text can be read properly even if the person has visual field defects.

[0069] It is also known that the likelihood of developing glaucoma increases for people in their 40s and older. For this reason, an age-related threshold for visual field loss may be set. That is, when the identification unit 233 identifies that the age is equal to or greater than this threshold, regardless of whether or not a visual impairment has been identified, a certain region may be moved as described in FIG. 8.

[0070] (Details of Activity A004) FIG. 9 shows an example of the recording screen 6 displayed on the display unit 34 of the user terminal 3. The recording screen 6 is an example of a screen that is displayed when receiving (recording) audio information d2. The recording screen 6 includes an area 61, an area 62, a record button 63, a stop button 64, and an area 65.

[0071] Area 61 is an area where instructions regarding speech are displayed to the subject. In the example of FIG. 9, the instruction displayed is "After tapping the record button, please say the following." Area 62 is an area where the specific speech content and instructions to be spoken by the subject are displayed. In the example of FIG. 9, the speech content "katama" and the instruction "as quickly as possible" are displayed. As described with reference to FIG. 8, areas 61 and 62 may also be moved for activity A004.

[0072] The record button 63 is a button for starting recording. The stop button 64 is a button for stopping recording. An area 65 is an area where a visual indication is displayed that the subject's voice is being recorded. The area 65 remains displayed while recording is in progress, and disappears when recording is completed or stopped.

[0073] (Details of Activity A005) An example of a method for the test information acquisition unit 232b to acquire test information d21 including the results of a cognitive function test from the audio information d2 will be described below. One method is to measure and evaluate fluctuations in the speed of each "katama" repetition. Furthermore, in addition to the fixed speech, various speech formats may be combined. Furthermore, various evaluation methods, such as fluctuations in the movement of the feet and hips while walking and the movement of the eyes, may also be combined.

[0074] (Details of Activity A006) The predetermined reference information dref used by the evaluation unit 234 can be configured as a table for associating the test information d21 and the lifestyle information d31 with whether or not to encourage a patient to see a doctor. The predetermined reference information dref can also be configured as a function for associating the test information d21 and the lifestyle information d31 with whether or not to encourage a patient to see a doctor.

[0075] Here, as described above, the items of the lifestyle information d31 include pattern information. According to this aspect, by using information on lifestyle rhythms as an example of lifestyle information, the accuracy of the recommendation to see a doctor can be improved. Also, as described in "3.1 Overview of Information in Information Processing," the pattern information includes at least one of items such as mealtime information and walking information. By generating the recommendation information drm based on the pattern information, it is possible to encourage a person to see a medical institution in advance, based on specific lifestyle information, before the condition worsens.

[0076] The items of the lifestyle information d31 include risky behavior information. According to this embodiment, information on luxury items and the like can be used as an example of lifestyle information, thereby improving the accuracy of the recommendation to visit a medical institution. Furthermore, the risky behavior information includes at least one of items such as drinking information and smoking information. By generating the recommendation information drm based on the risky behavior information, it is possible to encourage a person to visit a medical institution in advance, based on specific risky behavior information, before the situation worsens.

[0077] For example, the reference information dref may include scores assigned to the results of the test information d21 (level of cognitive function) and the lifestyle information d31 (pattern information and risky behavior information). When the total score exceeds a threshold, the evaluation unit 234 generates consultation recommendation information drm recommending that the subject visit a medical institution. In this case, the score of the test information d21, the score of the pattern information of the lifestyle information d31, and the score of the risky behavior information of the lifestyle information d31 are unified and evaluated using the total score, making the evaluation easy.

[0078] Furthermore, the results of the test information d21, the score of the pattern information of the lifestyle information d31, and the score of the risky behavior information of the lifestyle information d31 may be evaluated independently. In this case, for example, if all of these three results satisfy their respective predetermined criteria, a consultation to a medical institution is not recommended, but if at least one of the three results does not satisfy the corresponding criterion, a consultation to a medical institution is recommended.

[0079] The following describes how to convert the score of the pattern information of the lifestyle information d31. The recommendation to visit a medical institution can be determined based on the magnitude of the risk factor in the pattern information. Here, the magnitude of the risk factor can be determined based on the regularity of the pattern information over a predetermined period. The pattern information includes items such as mealtime information. Since disruption of the regularity of these items is considered to increase the likelihood of health problems, a higher score should be set for lower regularity. For example, with regard to GPS information, if a person is present at a desired location at a desired time, it can be evaluated as having a highly regular behavior and a higher score can be set. Furthermore, with regard to medication information, the more regularly a person takes their medication each day, the more regular the behavior can be evaluated and a higher score can be set. Conversely, the more frequently a person forgets to take their medication, the lower the score can be set. In this way, the pattern information can be scored taking into account the degree of regularity. The score of the pattern information can be calculated by summing the scores of these items (e.g., mealtime information). According to this aspect, disruption of the regularity of one's lifestyle increases the likelihood of health problems, and by evaluating this, the accuracy of the recommendation to visit a medical institution can be improved.

[0080] The following describes how to convert the score of the risky behavior information in the lifestyle information d31. The recommendation to visit a medical institution can be determined based on the magnitude of the risk factor in the risky behavior information. Here, the magnitude of the risk factor can be determined based on the frequency or amount of the risky behavior information over a predetermined period of time.

[0081] The risk behavior information includes items such as drinking information, and since it can be considered that the likelihood of health damage increases when such items apply (e.g., high frequency, large amount), a higher score should be set. For example, with regard to snoring information in the sleep respiration information, a higher score should be set if, for example, the subject snores loudly or is in a state of sleep apnea, as this increases the likelihood of health damage. The score for the risk behavior information can then be calculated by summing the scores for these items (e.g., drinking information). According to this aspect, the likelihood of health damage increases depending on the frequency and amount of preferences (e.g., smoking, drinking, long videos) and unintentional behaviors (e.g., snoring, apnea during sleep, falls), and by evaluating these, the accuracy of medical consultation recommendations can be improved.

[0082] In the above, the recommendation to visit a medical institution is based on the magnitude of the risk factor in the pattern information, but this is not limited to this and may be determined based on the presence or absence of the risk factor in the pattern information. In other words, there are only two patterns of scores: when it is determined that there is a pattern and when it is determined that there is no pattern. The same applies to the risk factors in the risk behavior information.

[0083] (Details of Activity A007) FIG. 10 shows an example of a screen 7 displaying results (such as the level of cognitive function and whether or not a medical examination is recommended) displayed on the display unit 34 of the user terminal 3. The screen 7 includes an area 71. The area 71 displays test information d21 including the results of a test on the user's cognitive function and consultation recommendation information drm for recommending the user (subject) to visit a medical institution. In the example shown in FIG. 10, the test information d21 displays "Your level is XXX." XXX displays, for example, a number indicating the level of cognitive function. Furthermore, the consultation recommendation information drm displays "We recommend that you visit a medical institution." This indicates that the user (subject) is recommended to visit a medical institution. Although not displayed in the area 71 shown in FIG. 10, previous test information d21 and consultation recommendation information drm may also be displayed in the area 71.

[0084] 11 shows an example of a medical institution presentation screen 9 displayed on the display unit 34 of the user terminal 3. As shown in FIG. 11, additional information other than that on the screen 7 may be presented. The medical institution presentation screen 9 has an area 91, an area 92, an area 93, an operation button 94, an area 95, and an operation button 96.

[0085] Area 91 is an area where a notification indicating medical institutions recommended to the user is displayed. Area 92 is an area where a map generated based on the medical institutions recommended to the user and location information related to the user's home is displayed. Area 92 includes a home icon 921 and medical institution icons 922 and 923. The home icon 921 is displayed at a position corresponding to the location information related to the user's home, i.e., the home address. The medical institution icons 922 and 923 are displayed at positions corresponding to the location information related to each medical institution, i.e., the medical institution's address. Here, the medical institution can be determined based on the basic information d1.

[0086] Areas 93 and 95 are areas for displaying information about the recommended medical institution displayed in area 92. In this embodiment, area 93 displays information about the medical institution corresponding to medical institution icon 922. Area 95 displays information about the medical institution corresponding to medical institution icon 923. Note that information about medical institutions may be displayed in descending order of priority as recommended medical institutions.

[0087] An operation button 94 is a button for making an appointment for an examination at a medical institution displayed in the area 93. An operation button 96 is a button for making an appointment for an examination at a medical institution displayed in the area 95.

[0088] (Details of Activity A008) The contents of the screen 7 are displayed on the display unit 34 of the user terminal 3, and are also notified (presented) to recipients other than the subject via email, a dedicated application, or the like. That is, in activity A008, which is an example of a notification step, the consultation recommendation information drm is notified to a pre-registered registered terminal. The registered terminal may include, for example, at least one of a terminal of the user's family member and a terminal associated with a nursing facility used by the user. According to this embodiment, by notifying not only the patient but also family members or medical professionals, it is possible to encourage them to consult a doctor. The notification method is not limited to text, but may also be, for example, a method of sending an image (e.g., an illustration) via a telephone answering machine or a dedicated account of a corresponding SNS.

[0089] For example, if an elderly person who attends day care every few days begins to repeatedly forget to take their medicine, the caregiver or medical professional can input the missed dose as medicine-taking information into the user terminal 3. This input information is sent from the user terminal 3 to the information processing device 2. When the subject executes the information processing method described in the embodiment, consultation recommendation information drm is generated that reflects the information about the missed dose of medicine, and the subject, family members, etc., and medical professionals can appropriately understand the subject's condition (deterioration of cognitive function).

[0090] The image displayed to the presentation target may be the same as that on the screen 7, or may have substantially the same content but with a different expression. Furthermore, the content notified (presented) to the presentation target may include content different from the information on the screen 7 of the user terminal 3. For example, because medical professionals have specialized knowledge, the examination information d21 and consultation recommendation information drm notified (presented) to medical professionals may include content that is explained in more detail than that provided to the subject.

[0091] 4. Variations The information processing system 1 may have the following configuration.

[0092] 4.1 Modification 1: Medical Information Acquisition Unit 232c Fig. 12 is an activity diagram showing an example of the flow of information processing executed in the information processing system 1 according to Modification 1. As shown in Fig. 12, the acquisition unit 232 of the processor 23 may further include a medical information acquisition unit 232c. The medical information acquisition unit 232c is configured to acquire medical information d41 based on information received by the reception unit 231 (information d4 related to medical treatment received by the subject).

[0093] The medical information d41 can be acquired, for example, as an activity (herein referred to as activity A002a for convenience) parallel to the activity A002 described in the embodiment. That is, in activity A001, the receiving unit 231 receives information d4 related to the medical treatment received by the subject, and stores the information in the storage unit 22. Then, in activity A002a, the acquiring unit 232 (medical information acquiring unit 232c) acquires the medical information d41 of the user (subject) using the information d4. This activity is an example of a third acquisition step.

[0094] The same applies to the medical information d41 as explained in "3.3.1. Details of Activity A002" regarding the lifestyle information d31. That is, the acquisition process of the medical information d41 may include a process (preprocessing) of adjusting (e.g., changing, selecting, organizing, deleting, etc.) the information d4 into information necessary for the evaluation unit 234 of the information processing system 1 to assess cognitive function. On the other hand, part or all of the medical information d41 may be the same as the information d4.

[0095] In this modified example, activities A007 and A008 (an example of a notification step) notify (present) consultation recommendation information drm based on lifestyle information d31, examination information d21, medical information d41, and predetermined reference information dref. According to this aspect, for example, even if the results of a visit to a dentist are used, it may be possible to determine whether health is impaired, and by utilizing this, the accuracy of consultation recommendation can be improved.

[0096] The information d4 related to the medical care received by the subject is information for acquiring the medical information d41, and is not particularly limited to a particular medical field (medical institution). For example, medical fields (medical institutions) include dentistry, internal medicine, surgery, psychosomatic medicine, psychiatry, neurology, otolaryngology, and geriatrics. Information d4 can be, for example, information obtained by a medical professional at a nursing home from the subject. Information d4 can also be the contents of a medication notebook, the contents of a medical record prepared by a doctor or other medical professional (including the results of the medical examination), the contents of a prescription, and the contents of various physical examinations such as health checkups. These may be combined or used individually.

[0097] The medical information d41 includes information based on visits to medical institutions other than the medical institution related to the test information d21, or information based on visits to medical care items other than the medical care items corresponding to the test information d21. Here, the medical institutions other than the medical institutions will be described. In one example of the embodiment, the test information d21 contains content related to cognitive function, and therefore corresponds to medical institutions such as psychiatry, neurology, and geriatrics. Therefore, information based on visits to medical institutions other than the medical institution related to the test information d21 may include, for example, information based on visits to dentistry, internal medicine, surgery, psychosomatic medicine, and otolaryngology. Furthermore, the medical care items other than the medical care items corresponding to the test information d21 are information based on visits to medical care items other than cognitive function.

[0098] It is known that when cognitive function declines (dementia or mild cognitive impairment occurs), diabetes is more likely to occur concomitantly, and patients who have had diabetes are at a higher risk of dementia or cognitive impairment. In other words, there is a correlation between diabetes and cognitive function. For this reason, it is preferable that the medical information d41 includes information on whether or not the patient has been diagnosed with diabetes.

[0099] The medical information d41 can be acquired based on the above-described information d4. The medical information d41 has content obtained by adjusting the above-described information d4 using the function of the acquisition unit 232, but the medical information d41 does not necessarily need to be distinguished from this information d4 and may have the same content. In other words, the information d4 itself may be the medical information d41.

[0100] The information based on the medical visit in the medical information d41 preferably includes at least one of information regarding the amount of prescription medication, information regarding changes in the amount of prescription medication, information regarding the details of the diagnosis, and information regarding changes in the details of the diagnosis. According to this aspect, the accuracy of the recommendation to visit a doctor can be improved based on more specific information.

[0101] The information based on the medical examination in the medical information d41 preferably includes at least one of brain MRI information, PET information, hearing information, dental information, oral function information, blood glucose level information, blood cholesterol information, bone density information, bone X-ray information, swallowing disorder information, and CT data. According to this embodiment, the accuracy of the recommendation to undergo a medical examination can be improved based on more specific information.

[0102] The following describes how the evaluation unit 234 converts the score of the medical information d41. The recommendation to visit a medical institution can be determined based on the magnitude of the risk factors in the medical information d41. The "depending on the magnitude of the risk factors" may refer to, for example, whether the timing of the notification remains the same or whether the notification is urged to visit a medical institution immediately or within a certain period of time. The timing of the notification may also be set in advance. A predetermined number of days may be set, and the notification may be issued when the set number of days has been reached or when the number of days has fallen below the set number. Here, the magnitude of the risk factors can be determined according to each item of the medical information d41 (e.g., information regarding the dosage of a prescription, brain MRI information, etc.). The score for each item can be set in advance, but it is preferable to assign a weight to the score. For example, the results of the brain MRI information may be given a higher weight and a higher score may be assigned. The evaluation unit 234 can calculate the score of the medical information d41 by summing the scores of these items. As described in the embodiment, this score may be evaluated in a unified manner with the examination information d21, etc., or independently.

[0103] 4.2 Variation 2: Regarding the test information d21 (Variation 2-1: Regarding the display of the speech training screen) FIG. 13 shows an example of a speech training screen 8 displayed when speech training is provided in the information processing system 1 according to the second modification. For example, if the subject is from a cold region, it is likely that the subject's intonation and mouth opening will be different from those of a person from a non-cold region. This may result in a measurement error in the speech information d2, potentially reducing the accuracy of the test information d21. For this reason, as shown in FIG. 13, when the identification unit 233 identifies the subject's hometown as a predetermined region based on the basic information d1, the identification unit 233 may display the speech training screen 8 shown in FIG. 13.

[0104] Although a person from a cold region is used as an example here, the present invention is not limited to this, and can also be applied to a person from a place where an accent is spoken.

[0105] The speech training screen 8 includes an area 81, an area 82, and an area 83. Area 81 displays a video of the instructor 81a, showing the instructor 81a uttering the test word "katama." Area 82 displays a video (for example, a video captured by the camera of the user terminal 3) showing the current situation of the test subject 82a. Area 83 displays an instruction to the test subject: "Please pronounce katama as quickly as possible."

[0106] The subject can check the shape of the instructor's mouth while watching the video of the subject 82a and checking the current shape of his or her mouth, which makes it easier for the subject to properly utter the predetermined test word "katama." This allows the receiving unit 231 to receive appropriate voice information d2, making it possible to acquire (generate) more accurate test information d21.

[0107] The speech training screen 8 shown in Fig. 13 can be displayed at various times. For example, it can be displayed when accepting voice input in activity A004. In this case, activity A004 may detect that the person is from a predetermined region (a region where the language has an accent) and switch from the screen shown in Fig. 9 to the screen shown in Fig. 13. In other words, it detects that the person is from a predetermined region, provides speech training, and has the person rephrase the predetermined test word "katama." The detection method may be to analyze the voice information d2 itself, or to analyze the shape of the mouth with a camera.

[0108] (Variation 2-2: Change in judgment criteria) As described in Modification 2-1, if the subject is from a predetermined region, measurement errors may occur in the audio information d2. Therefore, a correction may be added to the level of cognitive function output by the test information acquisition unit 232b. For example, when it is identified or detected that the subject is from a predetermined region, a predetermined correction value that improves cognitive function may be added to the level of cognitive function output by the test information acquisition unit 232b. Alternatively, this may be addressed by changing the threshold value for cognitive function (for example, the threshold value that distinguishes between test results indicating normal cognitive function and test results indicating low cognitive function). This also achieves the same effect as adding a correction value.

[0109] (Variation 3: Regarding the test information d21) In the embodiment, an example has been described in which the test information d21 is acquired by analyzing the audio information d2, but the present invention is not limited to this. The acquisition unit 232 (test information acquisition unit 232b) may acquire predetermined test information d21 from outside the information processing system 1, and the evaluation unit 234 may generate the consultation recommendation information drm using this test information d21. In this case, the test information acquisition unit 232b may not have the function of a trained model.

[0110] [others] The lifestyle information d31 or medical information d41 described in the embodiments may include information about the subject's eye movement. This is because characteristics appear in eye movement when cognitive function declines. Furthermore, the lifestyle information d31 or medical information d41 described in the embodiments may include information about swaying during walking and information about consistency in hip movement. This is because characteristics also appear when cognitive function declines.

[0111] In the above embodiment, the information processing device 2 performs various storage and control operations, 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.

[0112] 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 or server may be installed outside Japan, and the user terminal 3 may be installed in Japan. Similarly, a medical professional may access the information processing device 2 installed in Japan from outside Japan using his or her own user terminal 3. According to such an embodiment, a more convenient experience can be provided to the user through various management forms.

[0113] In one embodiment, the reception unit 231, the acquisition unit 232, the identification unit 233, the evaluation unit 234, and the presentation unit 235 are described as functional units implemented by the processor 23 of the information processing device 2, but at least some of them may be implemented as functional units implemented by another server. Alternatively, they may be implemented as functional units implemented by the processor 33 of the user terminal 3. Furthermore, the various pieces of information described in the above example may be stored not only in the storage unit 22 of the information processing device 2, but also in a distributed manner in other external devices.

[0114] Furthermore, it may be provided in the following aspects.

[0115] (1) An information processing system comprising at least one processor, the processor being configured to execute the following steps by reading a program: a first acquisition step acquiring lifestyle information relating to a user's lifestyle; a second acquisition step acquiring test information including test results relating to the user's cognitive function; and a notification step notifying the user of recommendation information for recommending that the user visit a medical institution based on the lifestyle information, the test information, and predetermined reference information.

[0116] According to this aspect, it is possible to prevent the user's cognitive function from causing problems in daily life. Specifically, it is possible to encourage the user to visit a medical institution before their condition worsens, which is useful for the user's health.

[0117] (2) In the information processing system described in (1) above, the lifestyle information includes pattern information relating to the user's daily lifestyle patterns.

[0118] According to this aspect, by using information about life rhythms as an example of lifestyle information, it is possible to improve the accuracy of the recommendation to see a doctor.

[0119] (3) In the information processing system described in (2) above, the pattern information includes at least one of mealtime information, walking information, tooth brushing information, bathing information, sleep information, exercise content information, GPS information, water heater usage information, and medication information.

[0120] According to this aspect, it is possible to prompt a patient to visit a medical institution before the condition worsens, based on specific lifestyle information.

[0121] (4) In the information processing system described in (2) or (3) above, the recommendation to visit a medical institution in the notification step is determined based on the magnitude of the risk factor in the pattern information, and the magnitude of the risk factor is determined based on the regularity of the pattern information over a predetermined period of time.

[0122] According to this aspect, if the regularity of one's daily rhythm is disrupted, the possibility of health being impaired increases, and by evaluating this, the accuracy of the recommendation to see a doctor can be improved.

[0123] (5) In the information processing system according to any one of (1) to (4) above, the lifestyle information includes risky behavior information relating to the user's preferences or unintentional behavior.

[0124] According to this aspect, information on luxury items and the like can be used as an example of lifestyle information, thereby improving the accuracy of the recommendation to see a doctor.

[0125] (6) In the information processing system described in (5) above, the risk behavior information includes at least one of drinking information, smoking information, video viewing status information, sleep breathing information, and fall information.

[0126] According to this aspect, it is possible to prompt a person to visit a medical institution in advance, before the situation worsens, based on specific risky behavior information.

[0127] (7) In the information processing system described in (5) or (6) above, the recommendation to visit a medical institution in the notification step is determined based on the magnitude of the risk factor in the risk behavior information, and the magnitude of the risk factor is determined based on the frequency or amount related to the risk behavior information over a predetermined period.

[0128] According to this aspect, the possibility of damaging health increases depending on the frequency and amount of preferences (e.g., smoking, drinking, watching long videos) and unintentional actions (e.g., snoring, apnea during sleep, falls), so by evaluating these, the accuracy of recommending medical examinations can be improved.

[0129] (8) In the information processing system described in any one of (1) to (7) above, in the third acquisition step, medical information of the user is acquired, and the medical information includes information based on a visit to a medical institution other than the medical institution related to the test information, or information based on a visit to a medical item other than the medical item corresponding to the test information, and in the notification step, the system notifies the user of the recommended medical examination information based on the lifestyle information, the test information, the medical information, and the predetermined reference information.

[0130] According to this aspect, for example, even if the results of a visit to a dentist are used, it may be possible to determine whether or not health is being impaired, and by utilizing this, the accuracy of the recommendation to visit a dentist can be improved.
