Digital therapeutic methods, systems, and computer programs that provide personalized training for the improvement of mild cognitive impairment
[0001] The present invention relates to a digital therapeutic method, system, and computer program for providing personalized training for the improvement of mild cognitive impairment, and more specifically, to a digital therapeutic method, system, and computer program for providing personalized training for the improvement of mild cognitive impairment using a recall diary generated based on personally taken photographic information to help maintain episodic memories that are problematic in mild cognitive impairment.
[0002] Mild Cognitive Impairment (MCI), the stage immediately preceding dementia, begins with symptoms caused by the atrophy of the hippocampus located in the medial temporal lobe of the cerebrum. Among forms of MCI, amnestic MCI (aMCI), characterized by impairment in episodic memory, is the most common. Episodic memory refers to the process of recalling facts or information by associating them with personal events or past facts from the moment they entered the memory structure. In aMCI, the episodic memory capacity controlled by the hippocampus declines, leading to frequent symptoms of forgetting previous memories, particularly recent ones, and failing to recover them.
[0003] One method to prevent mild cognitive impairment from progressing to dementia is cognitive intervention therapy. This therapy is a treatment method that maintains cognitive function by continuously stimulating the user's cognitive abilities, and it proceeds by repeatedly training the impaired cognitive functions. However, there is a problem in that when training cognitive functions, focusing on the memory of general knowledge does not help stimulate the brain areas responsible for episodic memory; instead, the brain stimulation is very limited, making it impossible to provide sufficient stimulation for memory.
[0004] In cognitive intervention therapy, reminiscence therapy, which involves recalling places or times spent with family based on memories of family or daily life, is the most effective. While writing a diary is a method for this purpose, it can be cumbersome and difficult for those unaccustomed to writing; furthermore, since diaries are generally written after the day's activities are over, it is difficult to verify the accuracy of one's memories.
[0005] Accordingly, the objective of the present invention is to provide a digital therapy method, system, and computer program for providing personalized training for the improvement of mild cognitive impairment, which helps maintain episodic memory by having a patient with mild cognitive impairment write a recollection diary using photographic data taken directly by the patient, and activates memory through directly experienced events by providing quizzes generated using information recorded in the recollection diary.
[0006] To achieve the objectives of the present invention as described above, the digital treatment method of the present invention comprises: (a) a step in which, when a memory photo that a user wishes to remember is captured through a user terminal, photo data for the memory photo is generated and transmitted to a cognitive training provider; (b) a step in which the photo data is stored in the cognitive training provider as a recall diary recording daily activities; (c) a step in which, when a predetermined period has elapsed since the time the memory photo was captured, quiz information for the memory photo is generated from the recall diary; (d) a step in which the quiz information is transmitted from the cognitive training provider to the user terminal and displayed; (e) a step in which, when response information for the quiz information is input into the user terminal, the response information is transmitted from the user terminal to the cognitive training provider; and (f) a step in which the user's memory level is evaluated through an analysis of the accuracy rate of the response information.
[0007] The above step (f) is characterized by the fact that if the daily correct answer rate of the response information for the question submitted on the day is 100%, the user's memory level is evaluated as increasing; if the daily correct answer rate is 50% or more and less than 100%, if the daily correct answer rate is less than 50% and the correct answer rate one day prior is 50% or more, and if the daily correct answer rate and the correct answer rate one day prior are less than 50% and the correct answer rate two days prior is 50% or more, the user's memory level is evaluated as having no change; and if the daily correct answer rate, the correct answer rate one day prior, and the correct answer rate two days prior are all less than 50%, the user's memory level is evaluated as decreasing.
[0008] The above step (c) is a step of generating the quiz information such that, if the user's memory level is evaluated as either a decrease or no change, one incorrect question among the questions submitted on that day is included.
[0009] Additionally, the above step (c) is a step of generating new quiz information for all items when the user's memory level is evaluated to have increased.
[0010] The above step (b) is a step in which at least one of the following is extracted from the photo data: location information of the place where the memory photo was taken, time information of when the memory photo was taken, and object information regarding a person or object in the memory photo, and stored as text data in the memory diary.
[0011] The digital treatment method of the present invention may further include a step of performing at least one operation among modification, addition, and deletion on the data stored in the recall diary through the user terminal.
[0012] Here, the above photo data is characterized by being generated through a cognitive training application for performing customized training, either physical training or dietary training, for improving mild cognitive impairment, and transmitted to the cognitive training providing device.
[0013] Meanwhile, as a computer program stored on a computer-readable medium, when the computer program is executed on at least one processor of a device, it performs steps for providing personalized training for improving mild cognitive impairment, wherein the steps include: (a) a step in which, when a memory photo that a user wishes to remember is captured through a user terminal, photo data for the memory photo is generated and transmitted to a cognitive training provider; (b) a step in which the photo data is stored in the cognitive training provider as a recall diary recording daily activities; (c) a step in which, when a predetermined period set from the time the memory photo was captured is elapsed, quiz information for the memory photo is generated from the recall diary; (d) a step in which the quiz information is transmitted from the cognitive training provider to the user terminal and displayed; (e) a step in which, when response information for the quiz information is input into the user terminal, the response information is transmitted from the user terminal to the cognitive training provider; and (f) a step in which the user's memory level is evaluated through an analysis of the accuracy rate of the response information.
[0014] A digital therapeutic system for providing personalized training for the improvement of mild cognitive impairment comprises: a user terminal that generates photo data for a memory photo when a memory photo that the user wishes to remember is taken; and a cognitive training providing device that stores the photo data transmitted from the user terminal as a recall diary recording daily activities; wherein the cognitive training providing device generates quiz information using the recall diary and transmits it to the user terminal, and when response information regarding the quiz information is input into the user terminal, receives and analyzes the response information from the user terminal to evaluate the user's memory level.
[0015] Here, the cognitive training providing device is characterized by evaluating the user's memory level as higher when the daily correct answer rate of the response information to the question submitted on the day is 100%, evaluating the user's memory level as unchanged in at least one of the following cases: when the daily correct answer rate is 50% or higher and less than 100%, when the daily correct answer rate is less than 50% and the correct answer rate one day prior is 50% or higher, and when the daily correct answer rate and the correct answer rate one day prior are less than 50% and the correct answer rate two days prior is 50% or higher, and evaluating the user's memory level as lower when the daily correct answer rate, the correct answer rate one day prior, and the correct answer rate two days prior are all less than 50%.
[0016] Through the digital therapeutic method, system, and computer program of the present invention that provide personalized training for improving mild cognitive impairment, the memory of a patient with mild cognitive impairment can be activated through an event experienced directly.
[0017] In addition, by evaluating memory levels based on the accuracy rate and using this as a reference for generating the next quiz information, it is possible to generate and provide quiz information tailored to the memory level of patients with mild cognitive impairment, and to track trends in episodic memory ability over time through the memory level evaluation results.

[0021] FIG. 7 is a flowchart illustrating a method for evaluating a user's memory level in a digital therapeutic system according to an embodiment of the present invention.
[0022] Hereinafter, a digital therapeutic method, system, and computer program (hereinafter referred to as the "digital therapeutic method, digital therapeutic system, and computer program") providing personalized training for improving mild cognitive impairment according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.
[0023] FIG. 1 is a diagram briefly illustrating the configuration of a digital treatment system according to one embodiment of the present invention.
[0024] Referring to FIG. 1, the digital therapeutic system of the present invention includes a cognitive training provider (100) and a user terminal (200) that provide personalized training for the improvement of mild cognitive impairment. The cognitive training provider (100) and the user terminal (200) are connected via a wired / wireless network (300) to transmit and receive data. The wired / wireless network (300) is a general term for a communication network that supports various communication standards or protocols for pairing or data transmission and reception between the cognitive training provider (100) and the user terminal (200). Such a wired / wireless network (300) includes all communication networks currently or to be supported in the future according to the standards, and can support all one or more communication protocols for that purpose.
[0025] The cognitive training providing device (100) may be any device capable of transmitting or receiving data, contents, services, and applications. In the present invention, the cognitive training providing device (100) refers to a server, but is not limited thereto; it may also refer to a fixed device such as a PC (Personal Computer) or a mobile device such as a smartphone, tablet PC, or notebook, and unless specifically mentioned otherwise, it may be used to include all of them.
[0026] Here, a server refers to a device or system that transmits data to or receives data from various types of user terminals, namely clients. Examples of servers may include a web server or portal server that provides web pages, web content or web services, an advertising server that provides advertising data, a content server that provides content, a social network service (SNS) server that provides SNS, a service server provided by a manufacturer, a multichannel video programming distributor (MVPD) for providing video on demand (VoD) or streaming services, a service server that provides paid services, etc.
[0027] Meanwhile, the user terminal (200) of the present invention is connected to the cognitive training providing device (100) to transmit, receive, and display predetermined data. The user terminal (200) may be implemented as a mobile terminal such as a mobile phone, a smartphone, a tablet PC, an ultrabook, etc. However, it is not limited thereto and may also include a fixed device such as a PC (Personal Computer), a microprocessor, a mainframe computer, a digital processor, a device controller, etc.
[0028] A cognitive training application for personalized training to improve mild cognitive impairment is executed on the user terminal (200), and the patient with mild cognitive impairment writes a recollection diary through the cognitive training application. Here, the patient with mild cognitive impairment writes a recollection diary recording daily activities using photo data of memory photos taken directly of scenes, people, or objects to be remembered, and can input or modify relevant information regarding the captured memory photos. Photo data of memory photos taken on the user terminal (200) is transmitted to the cognitive training providing device (100) and stored as a recollection diary.
[0029] When a preset period is reached, the cognitive training providing device (100) generates quiz information regarding memory photos from a recall diary, and the quiz information is transmitted to and displayed on the user terminal (200). When response information regarding the quiz information is input into the user terminal (200), the response information is transmitted to the cognitive training providing device (100). Then, the cognitive training providing device (100) analyzes the response information and evaluates the user's memory level.
[0030] The cognitive training providing device (100) of the present invention includes a first storage unit (110), a first processor (120), and a first communication unit (130). Each component may be integrated, added, or omitted according to the specifications of the cognitive training providing device (100) actually implemented. That is, as needed, two or more components may be combined into one component, or one component may be subdivided into two or more components. Furthermore, the functions performed in each block are intended to explain embodiments of the present invention, and the specific operations or devices thereof do not limit the scope of the rights of the present invention.
[0031] The first storage unit (110) can store data that supports various functions of the cognitive training provider (100). That is, the first storage unit (110) can store a number of applications running on the cognitive training provider (100), data for the operation of the cognitive training provider (100), commands, and at least one program command. At least some of these applications may exist on the cognitive training provider (100) from the time of shipment for the basic functions of the cognitive training provider (100), or may be downloaded from an external server via wireless communication.
[0032] In the present invention, a cognitive training application is stored in the first storage unit (110), photo data regarding a memory photo taken by a user terminal (200) is stored in the form of a recollection diary, and response information transmitted from the user terminal (100) is stored. The cognitive training application stored in the first storage unit (110) is transmitted to and installed on the user terminal (200) via a wired / wireless network (300). The response information stored in the first storage unit (110) is analyzed by the first processor (120), which will be described later, to evaluate the user's memory level.
[0033] The first processor (120) can control the overall operation of the cognitive training provider (100) and can provide or process appropriate information or functions by processing signals, data, information, etc. that are input or output through the components of the cognitive training provider (100) or by running an application program stored in the first storage unit (110). In addition, the first processor (120) can control at least some of the components of the cognitive training provider (100) to run an application program stored in the first storage unit (110). Furthermore, the first processor (120) can operate at least two or more of the components included in the cognitive training provider (100) in combination with each other to run an application program.
[0034] The first processor (120) may be composed of one or more cores and may be any of the various commercial processors. For example, the first processor (120) may include the device's Central Processing Unit (CPU), General Purpose Graphics Processing Unit (GPUGP), Tensor Processing Unit (TPU), etc. Additionally, the first processor (120) may be composed of a dual processor or other multi-processor architecture.
[0035] In the present invention, the first processor (120) stores a memory photo transmitted from the user terminal (200) in the form of a recollection diary in the first storage unit (110). Additionally, it generates quiz information from the recollection diary stored in the first storage unit (110) and controls the first communication unit (130) so that the quiz information is transmitted to the user terminal (200). Furthermore, when the first processor (120) receives response information regarding the quiz information from the user terminal (200), it analyzes the response information and evaluates the user's memory level.
[0036] For example, if the recall period set by the user is one week and five questions are submitted every day, the first processor (120) generates quiz information containing five questions every day for one week. The generated quiz information is transmitted to and displayed on the user terminal (200), and when a patient with mild cognitive impairment inputs answers to the five questions into the user terminal (200), response information is generated and transmitted to the cognitive training providing device (100).
[0037] As a result of analyzing response information in the first processor (120), if the correct answer rate for the 5 questions submitted on the day is 100%, the user's memory level is evaluated as higher than the current level. If the correct answer rate for the questions submitted over the past 3 days is all less than 50%, the user's memory level is evaluated as lower than the current level. In this case, a warning message is sent to an operator terminal (not shown) to identify the cause of the rapid decrease in the correct answer rate. And if the correct answer rate on the day is 50% or more and less than 100%, or if the correct answer rate on the day is less than 50% and the correct answer rate one day ago is 50% or more, or if the correct answer rate on the day and the correct answer rate one day ago is less than 50% and the correct answer rate two days ago is 50% or more, the user's memory level is evaluated as having no change.
[0038] The first processor (120) generates quiz information such that when the memory level is evaluated as unchanged or decreased, one of the incorrect questions is included in the questions to be submitted later. And when the memory level is evaluated as increased, the first processor (120) generates quiz information such that all questions to be submitted later become new questions.
[0039] The first communication unit (130) may include one or more modules that enable wired / wireless communication between the cognitive training provider (100) and a wired / wireless network (300), between the cognitive training provider (100) and another device, or between the cognitive training provider (100) and an external server. Additionally, the first communication unit (130) may include one or more modules that connect the cognitive training provider (100) to one or more networks. Furthermore, the first communication unit (130) refers to a module for connecting to a wired / wireless network (300), which may be embedded in or externally mounted on the cognitive training provider (100) and configured to transmit and receive wired / wireless signals.
[0040] In the present invention, the first communication unit (130) transmits a cognitive training application to a user terminal (200) so that it is installed on the user terminal (200). In addition, it transmits quiz information generated by the first processor (120) and receives response information obtained through the cognitive training application from the user terminal (200).
[0041] Meanwhile, the user terminal (200) of the present invention can be paired or connected with the cognitive training providing device (100) via a wired / wireless network (300), and can transmit, receive, and display certain data through this. The user terminal (200) includes a second storage unit (210), a second processor (220), a second communication unit (230), a user interface unit (240), a shooting unit (250), and a speaker (260).
[0042] Each component may be integrated, added, or omitted according to the specifications of the actual user terminal (200) being implemented. That is, as needed, two or more components may be combined into one component, or one component may be subdivided into two or more components. In addition, the functions performed in each block are intended to explain the embodiments of the present disclosure, and the specific operations or devices thereof do not limit the scope of the present invention.
[0043] The second storage unit (210) stores a cognitive training application downloaded from the cognitive training providing device (100), quiz information transmitted from the cognitive training providing device (100), and content for treatment or training.
[0044] The second processor (220) controls the execution of a cognitive training application stored in the second storage unit (210) so that content and quiz information for treatment or training are displayed through the display unit (250). Additionally, the second processor (220) controls the generation of response information according to a user command input through the user interface unit (240) and transmission to the cognitive training providing device (100).
[0045] The second communication unit (230) communicates with the cognitive training providing device (100) via a wired / wireless network (300) and receives cognitive training applications, quiz information, and content for treatment or training transmitted from the cognitive training providing device (100). In addition, it transmits photo data regarding memory photos taken through the shooting unit (250) and response information obtained through the cognitive training application to the cognitive training providing device (100).
[0046] The user interface unit (240) is configured to include a display unit that displays information processed by the user terminal (200) and an input unit that receives user commands implemented via a key or touch method. Through the user interface unit (240), information on the execution screen of an application running on the user terminal (200) or UI (User Interface) and GUI (Graphic User Interface) information corresponding to the execution screen information is displayed. Patients with mild cognitive impairment can input desired commands or information when running a cognitive training application through the user interface unit (240).
[0047] The shooting unit (250) may include one or more cameras. That is, the user terminal (200) includes one or more cameras on at least one side of the front or rear. The shooting unit (250) can process image frames, such as still images or video, obtained by an image sensor. The processed image frames may be displayed on the display unit (250) or stored in the second storage unit (210). In the present invention, photo data regarding a memory photo taken through the shooting unit (250) is transmitted to the cognitive training providing device (100) and stored as a recollection diary that records daily activities.
[0048] The speaker (260) outputs audio data received through the second communication unit (230) or stored in the second storage unit (210). Additionally, the speaker (260) outputs audio data related to functions performed on the user terminal (200). In the present invention, the speaker (260) outputs audio data related to the execution of a cognitive training application.
[0049] FIGS. 2 to 5 are drawings illustrating a cognitive training application implemented in a digital therapeutic system according to an embodiment of the present invention. As illustrated in FIGS. 2 to 5, the cognitive training application is displayed through a user interface unit (240) and operates by receiving user commands through the user interface unit (240).
[0050] Through the cognitive training application, physical training and dietary training are provided, and a reminiscence diary is written every day, so patients who wish to treat cognitive impairment can record their daily activities in photos and text. The second processor (220) randomly selects memory photos from the reminiscence diaries written by patients with mild cognitive impairment during a set period and generates quiz information related to the selected memory photos.
[0051] Figure 2 is a diagram illustrating a case where physical activity (410) is selected to perform physical training through a cognitive training application.
[0052] When a patient with mild cognitive impairment selects 'Start walking' among physical activities, the current speed, target speed, exercise distance, exercise time, and the number of steps helpful for treatment are displayed. If voice guidance is needed, the patient can select one of the walking training guides to receive guidance on adjusting walking speed or walking correctly through voice output via the speaker.
[0053] Additionally, by clicking the camera icon (400), you can take a memory photo before, during, or after starting or finishing the exercise and save it as a memory diary. The memory diary includes location information of the place where the memory photo was taken, date information of when the memory photo was taken, and object information regarding the people or objects captured in the memory photo. The object information includes information such as the type of object, the number of people, and gender.
[0054] Figure 3 is a diagram illustrating the case where a meal (420) is selected to perform dietary training through a cognitive training application.
[0055] Patients with mild cognitive impairment can check their brain health meal score by selecting the ingredients they will eat before eating. Additionally, before starting the meal, they can click the camera icon (400) to take a memory photo of the meal they will eat or the people they will eat with and save it as a memory diary. The memory diary includes location information of the place where the memory photo was taken, date and time information of the memory photo, and object information about the people or objects captured in the memory photo. The object information includes information such as the type of food captured, the number of people, and gender.
[0056] Figure 4 is a diagram illustrating the case where a diary (430) is selected in a cognitive training application.
[0057] As illustrated in FIGS. 2 and 3, when a memory photo is taken before physical activity or a meal, location information of the place where the memory photo was taken, date and time information of the memory photo, and object information regarding the person or object in the memory photo are extracted from the photo data and stored as text data in a memory diary. Then, when a patient with mild cognitive impairment selects a desired date, the people met and places visited on the selected date are displayed as text, as shown in FIG. 4.
[0058] Additionally, patients with mild cognitive impairment can select a desired date and modify, add, or delete the names of people met on the selected date, places visited, or food eaten. At this time, they can also select the camera icon (400) to take and save a new memory photo, or delete or modify existing memory photos.
[0059] FIG. 5 is a diagram illustrating the case where brain activity (440) is selected in a cognitive training application.
[0060] In the cognitive training providing device (100), quiz information regarding memory photos is generated using a recollection diary when the period set by the patient with mild cognitive impairment is reached. For example, if the period set by the patient with mild cognitive impairment is one week, quiz information is generated from the recollection diary written on July 7 after one week has passed since July 7. The generated quiz information is transmitted to and displayed on the user terminal (200), and the patient with mild cognitive impairment checks the quiz information and then inputs response information into the user terminal (200).
[0061] Here, when quiz information is received by the user terminal (200), a pop-up icon (not shown) is displayed on the user interface section (240), and the patient with mild cognitive impairment may touch or click the pop-up icon to display the quiz information as exemplified in FIG. 5. The generated quiz information includes a memory photo that the patient with mild cognitive impairment took and saved on July 7, which helps the patient with mild cognitive impairment recall events that occurred a week ago. In other words, memory can be activated through an event directly experienced by the patient with mild cognitive impairment.
[0062] When a patient with mild cognitive impairment inputs response information into a user terminal (200), the response information is transmitted to and stored by a cognitive training providing device (100). Then, the cognitive training providing device (100) analyzes the accuracy rate of the response information to evaluate the user's memory level, and then determines whether to include incorrect answers in the quiz information generation based on the evaluation result.
[0063] As explained above, by evaluating the memory level based on the accuracy rate and using this as a reference for generating the next quiz information, it is possible to generate and provide quiz information tailored to the patient's memory level.
[0064] FIG. 6 is a flowchart illustrating the operation of a digital treatment system according to one embodiment of the present invention.
[0065] According to FIG. 6, when a memory photo that a patient with mild cognitive impairment wishes to remember is captured through a user terminal (200) (S500-Y), photo data for the memory photo is generated and transmitted to a cognitive training provider (S510). That is, as exemplified in FIG. 2, when a camera icon (400) is selected before starting, during, or after physical training, to photograph a place to remember, a person accompanying the patient, or an object seen while passing by, photo data is generated and transmitted to a cognitive training provider. Alternatively, as exemplified in FIG. 3, when a table set before a meal is photographed during dietary training, photo data is generated and transmitted to a cognitive training provider. In the case of meals, the brain health meal score can be checked by selecting ingredients through a cognitive training application.
[0066] Photo data is stored in a cognitive training providing device as a recollection diary recording daily activities (S520). At this time, location information of the place where the memory photo was taken, date and time information of when the memory photo was taken, and object information about the person or object in the memory photo are extracted from the photo data and stored as text.
[0067] In addition, data stored as a memory diary can be modified, added, and deleted through a user terminal (200). That is, as described in FIG. 4, when a desired date is selected, the names of people met on the selected date, places visited, or food eaten are displayed as text, and the patient with mild cognitive impairment can modify, add, or delete the text. Additionally, new memory photos can be taken and saved, and existing memory photos can be deleted or modified.
[0068] After a memory photo is taken, when a predetermined period set by the user has elapsed (S530-Y), the cognitive training providing device (100) generates quiz information about the memory photo from the stored recollection diary (S540). That is, as exemplified in FIG. 5, when one week, which is the set period after the memory photo is taken, has elapsed, quiz information regarding who was with at the time and place where the memory photo was taken is generated.
[0069] The generated quiz information is transmitted from the cognitive training providing device (100) to the user terminal (200) and displayed (S550). For example, when quiz information is generated in the cognitive training providing device (100), the notification information is transmitted to the user terminal (200) and displayed as a pop-up icon, and when a patient with mild cognitive impairment selects the pop-up icon, the quiz information is displayed through the user interface unit (240) as exemplified in FIG. 5.
[0070] When response information for the quiz information is input into the user terminal (200) (S560-Y), the response information is transmitted from the user terminal (200) to the cognitive training providing device (100) (S570). Then, the cognitive training providing device (100) evaluates the user's memory level through an analysis of the correct answer rate for the response information (S580).
[0071] Through the process described above, training to activate memory is performed using events directly experienced by patients with mild cognitive impairment as a medium, and the trend of the patients' memory levels over time can be tracked.
[0072] FIG. 7 is a flowchart illustrating a method for evaluating a user's memory level in a digital therapeutic system according to an embodiment of the present invention.
[0073] First, when the accuracy rate of the response information for the questions submitted on the day is called the daily accuracy rate, if the daily accuracy rate is 100% (S600-Y), the user's memory level is evaluated as increased (S610). Then, on the next day, new quiz information is generated so that all questions are submitted as new questions (S620). For example, if quiz information containing 5 questions is generated from a reminiscence diary written on July 7 and provided through the user terminal (200) on July 14, and the user's response information entered into the user terminal (200) is analyzed and all 5 questions are correct, the user's memory level is evaluated as increased by the cognitive training providing device (100). Then, on July 15, quiz information containing 5 new questions is generated from a reminiscence diary written on July 8.
[0074] If the correct answer rate on the day is 50% or more but less than 100% (S630-Y), if the correct answer rate on the day is less than 50% (S640-Y), if the correct answer rate one day prior is 50% or more (S650-N), if the correct answer rate on the day and one day prior is less than 50% (S650-Y), or if the correct answer rate two days prior is 50% or more (S660-N), the user's memory level is evaluated as having no change (S670). In this case, quiz information is generated so that one of the incorrect answers is included on the next day (S690).
[0075] For example, if the correct answer rate is 80% based on the analysis of response information on July 14, the user's memory level is evaluated as having no change. Also, if the correct answer rate on July 14 is 40% and the correct answer rate on July 13 is 60%, the user's memory level is evaluated as having no change. Furthermore, if the correct answer rates on both July 14 and 13 are 20% and the correct answer rate on July 12 is 80%, the user's memory level is evaluated as having no change. In this case, on July 15, one of the incorrect answers from the 14th is included, and for the remainder, quiz information is generated that includes four new questions from the recollection diary written on July 8.
[0076] Meanwhile, if the correct answer rate for the day, the correct answer rate for the day before, and the correct answer rate for the day before are all less than 50% (S660-Y), the user's memory level is evaluated as lowered (S680). In this case, quiz information is generated so that one of the incorrect answers is included (S690). That is, on July 15, one of the incorrect answers from the 14th is included, and for the rest, quiz information is generated that includes four new questions from the recollection diary written on July 8.
[0077] By evaluating the memory level of patients with mild cognitive impairment through the process described above and using this as a reference for generating the next quiz information, it is possible to generate and provide quiz information tailored to the memory level of patients with mild cognitive impairment.
