Description

Technical Field

[0001] The present invention generally relates to an evaluation system, an evaluation method, a program, a server device, and a terminal device, and more particularly to an evaluation system, an evaluation method, a program, a server device, and a terminal device configured to evaluate the cognitive function of a target person. Background Art

[0002] Patent Document 1 discloses an elderly care system for notifying a guardian of a target person to be cared for of the status of commodity purchases made by the target person in a store. According to this system, the guardian can know whether the target person has purchased unnecessary commodities.

[0003] This system includes a management device for managing the status of a target person to be cared for and a guardian terminal device carried by the guardian.

[0004] The management device includes a communication unit and a controller. The communication unit communicates with the guardian terminal device and a person detection device for detecting a person who purchases commodities in the store. When the communication unit receives detection information from the person detection device, the controller determines based on the received detection information whether the person who purchases commodities in the store corresponds to a pre-registered target person. When it is determined that the person corresponds to the pre-registered target person, the controller enables the communication unit to send a purchase notice related to the commodity purchase status of the target person to the guardian terminal device.

[0005] In the system disclosed in Patent Document 1, when the target person purchases commodities, a purchase notice is sent to the guardian regardless of the degree of the cognitive function of the target person. This may increase the burden on the guardian who always receives the purchase notice. Therefore, there is room for improvement in terms of the convenience of the system disclosed in Patent Document 1.

[0021] (1) Overview

[0022] In recent years, with the advent of an aging society, people's attention has been focused on the increasing number of dementia patients. Dementia has progressive symptoms. Therefore, from the perspective of preventing dementia, people's attention has also been focused on mild cognitive impairment (MCI), which is the stage preceding dementia.

[0023] MCI is a state between the normal state (healthy state) and dementia. The main difference between MCI and dementia lies in whether the patient can live independently in daily life. More specifically, dementia patients have difficulties in performing daily activities such as eating, bathing, and using the toilet (i.e., basic activities of daily living (basic (ADL))). On the other hand, MCI patients do not have major difficulties in basic ADL. However, both dementia patients and MCI patients have difficulties in instrumental ADL, such as shopping, housework, and financial management, which are more complex activities than basic ADL.

[0024] The symptoms of MCI (i.e., the degree of decline in cognitive function) vary greatly. For example, there are also MCI patients whose degree of cognitive function (judgment) changes every day. Such MCI patients may, for example, happen to make unnecessary purchases on days when their cognitive function declines.

[0025] In view of the above problems, the evaluation system 100 according to the present embodiment is configured to evaluate the cognitive function of a purchaser when the purchaser makes an unnatural purchase. Then, if it is found that the cognitive function of the purchaser declines when making an unnatural purchase, the evaluation system 100 is configured to notify someone of this situation.

[0026] More specifically, as Figure 1 shown, the evaluation system 100 according to the present embodiment includes an information acquisition unit F11, an evaluation unit F14, and a judgment unit F12. The information acquisition unit F11 is configured to acquire information related to a target person H1 (purchaser) (see Figure 3Payment information related to the payment of remuneration to be made for the receipt of services. The evaluation unit F14 is configured to evaluate the cognitive function of the target person H1. The determination unit F12 is configured to determine whether it is necessary to evaluate the cognitive function of the target person H1 by using the acquisition of the payment information as a trigger. In the case where it is determined that the cognitive function of the target person H1 should be evaluated, the determination unit F12 enables the evaluation unit F14 to evaluate the cognitive function of the target person H1.

[0027] As Figure 1 shown, the evaluation system 100 according to the present embodiment further includes a notification unit F16. The evaluation unit F14 is configured to represent the cognitive function of the target person H1 by a numerical value indicating the degree of decline in the cognitive function of the target person H1. The notification unit F16 is configured to notify at least one selected from the target person H1 himself / herself, the family members of the target person H1, and the guardian of the target person H1 of cancellation information for canceling the payment of remuneration when the numerical value indicating the degree of decline in the cognitive function evaluated by the evaluation unit F14 is greater than a specified threshold.

[0028] The evaluation system 100 according to the present embodiment can determine whether an unnatural purchase is caused by a decline in the cognitive function of the purchaser when an unnatural purchase is made. Therefore, for example, assuming a decline in cognitive function during shopping, a person can take follow-up measures. Therefore, the evaluation system 100 can achieve improved convenience.

[0029] In addition, the evaluation system 100 according to the present embodiment determines the cognitive function of the target person H1 as needed by using the acquisition of the payment information as a trigger, and further enables the notification unit F16 to perform notification as needed. Therefore, for example, the evaluation system 100 can reduce the frequency of performing notifications. Therefore, the evaluation system 100 can achieve improved convenience.

[0030] Furthermore, for the target person H1 who is unaware of MCI or dementia himself / herself, the evaluation system 100 according to the present embodiment can determine whether it is necessary to evaluate the cognitive function by using the acquisition of the payment information as a trigger. Therefore, the evaluation system 100 can contribute to the early detection of patients with MCI or dementia.

[0031] (2) Details

[0032] Hereinafter, the evaluation system 100 according to the present embodiment will be described in more detail with reference to Figures 1 to 4 to.

[0033] (2.1) Overall structure

[0034] Figure 1 and Figure 2Shows the structure of the evaluation system 100 according to the present embodiment.

[0035] As Figure 1 shown, the evaluation system 100 includes a store device 10, a server device 20, and a terminal device 30. Note that the store device 10 and the terminal device 30 are not essential components of the evaluation system 100 and may be omitted from the components of the evaluation system 100.

[0036] As Figure 2 shown, the store device 10 is installed at the store 1. The server device 20 constitutes the main part of the evaluation system 100 according to the present embodiment. The server device 20 is installed, for example, at the facility of an organization that provides services using the evaluation system 100 according to the present embodiment. The terminal device 30 is, for example, an information terminal carried by the target person H1, a family member of the target person H1, or a guardian of the target person H1 (hereinafter, they may sometimes be referred to as "users").

[0037] As described above, the store device 10 is installed at the store 1. The store 1 in the present embodiment refers to an object that provides services to customers and customers pay remuneration for the provided services to the object.

[0038] In the present embodiment, service provision includes, for example, selling goods (articles; tangible objects).

[0039] Examples of the store 1 may include retail stores that directly sell goods to customers. Examples of retail stores may include convenience stores, supermarkets, department stores, pharmacies, clothing stores, electronics retail stores, and hardware stores.

[0040] In addition, examples of the store 1 may include virtual stores that indirectly sell goods to customers. The virtual store is configured to receive orders for goods from customers via a telecommunications line NT1 such as the Internet or a telephone line, send the goods to the customers according to the orders, and receive remuneration (price) from the customers by electronic payment, cash on delivery, or cash on arrival. Examples of virtual stores may include mail-order businesses. Examples of the forms of mail-order businesses may include online shopping, television shopping, and catalog sales.

[0041] In the present embodiment, service provision may include providing intangible objects. Examples of providing intangible objects may include providing services to give customers utility or satisfaction, etc. Examples of the store 1 (which may include virtual stores) that provides intangible objects may include restaurants, entertainment facilities, travel agencies, medical facilities, insurance agents, and video viewing services (which may include online).

[0042] In the present embodiment, there is no particular limitation on the form of the remuneration to be paid for service provision. Examples of the payment method of the remuneration include payment processing by credit card, prepaid card, electronic money, reward card (point card), cryptocurrency (so-called electronic money), and cash.

[0043] Hereinafter, for the sake of convenience of explanation, it is assumed that the store device 10 is installed at a retail store (e.g., an e-retail store) as the store 1.

[0044] In the store 1, for example, multiple types of goods are sold in a state of being displayed in the store. A customer selects a desired type of good from the multiple types of goods displayed in the store, and can purchase the good by making a payment for the good. "Payment" for a good means the settlement processing on the buyer side (i.e., the settlement processing required for the transaction) when the ownership of the good is transferred from the seller (store 1) to the buyer (customer) and the buyer pays the transferred remuneration (price) to the seller.

[0045] The store device 10 in the present embodiment is a point-of-sale (POS) terminal. In particular, the store device 10 in the present embodiment is a so-called "ID-POS" that can process ID-POS data. The "ID-POS data" mentioned here is data obtained by adding a "customer ID", which is identification information (ID) of a customer, to POS data. This type of POS terminal (ID-POS) acquires the identification information (customer ID) of a customer by authenticating the customer when the customer makes a purchase. Authentication of a customer can be achieved by various cards such as a membership card, a reward card (point card), and a credit card. Alternatively, authentication of a customer can be achieved by communication with a mobile information terminal carried by the customer, or biometric authentication (which may include face authentication).

[0046] For example, the store device 10 as described above can send payment information (as data) for purchasing goods at the store 1 to the server device 20 via the network NT1. In particular, the store device 10 in the present embodiment can process ID-POS data. Therefore, the store device 10 can output information related to the goods to be purchased (i.e., payment information) in a state associated with the identification information (customer ID) of the customer before or during bookkeeping.

[0047] More specifically, as Figure 1 shown, the store device 10 includes a communication unit 11 and a processing unit 12. The store device 10 of the present embodiment further includes a voice acquisition unit 13.

[0048] The communication unit 11 is a communication interface. The communication unit 11 is a communication interface that can be connected to the telecommunications line NT1 and has a function of communicating with another device via the telecommunications line NT1 (see Figure 2)。Therefore, the store device 10 is configured to communicate with the server device 20 via the telecommunications line NT1. For example, the telecommunications line NT1 consists of a network conforming to a single communication protocol. Optionally, the telecommunications line NT1 may consist of two or more networks conforming to different communication protocols. The communication protocol may be selected from various well-known wired communication standards and wireless communication standards. Although simplified in Figure 2 , the telecommunications line NT1 may include data communication devices such as relay hubs, switching hubs, bridges, gateways, and routers.

[0049] The voice acquisition unit 13 includes a microphone. The microphone converts the sound including the voice emitted by the customer into voice data (voice signal), and outputs the voice data to the outside via the communication unit 11. In the present embodiment, the voice acquisition unit 13 enables the communication unit 11 to send the voice data to the server device 20 via the telecommunications line NT1.

[0050] The processing unit 12 is configured to perform overall control of the store device 10, that is, control operations of the communication unit 11 and the voice acquisition unit 13. For example, the processing unit 12 may include a computer system including one or more processors (microprocessors) and one or more memories. The computer system performs the functions of the processing unit 12 by causing one or more processors to execute one or more programs (applications) stored in one or more memories. In the present embodiment, one or more programs to be executed by one or more processors are pre-stored in one or more memories of the processing unit 12. However, this is only an example and should not be construed as restrictive. One or more programs may also be distributed after being stored in a non-transitory storage medium such as a memory card, or downloaded via a telecommunications line such as the Internet.

[0051] As Figure 1 shown, the processing unit 12 includes an information generation unit F1 and a start command unit F2. The information generation unit F1 and the start command unit F2 represent functions to be realized by the processing unit 12, rather than physical components.

[0052] The information generation unit F1 generates payment information related to the remuneration that the customer (target person H1) should pay for receiving the service. In the present embodiment, since the store 1 is a retail store, receiving the service includes obtaining goods (purchasing items). The payment information generated by the information generation unit F1 may include: information related to the price (i.e., unit price) of individual goods related to the purchase; information related to the total price of the goods related to the purchase; information related to the quantity (i.e., amount) of the goods related to the purchase; and information related to the category of the goods related to the purchase.

[0053] Information related to the price of the merchandise may include at least one selected from a list price, a set price, and a suggested retail price.

[0054] Information related to the quantity of the merchandise may include: information related to the quantity of the merchandise by type related to the same purchase; and information related to the total number of all merchandise related to the same purchase.

[0055] The category of the merchandise is a label for classifying the merchandise according to its use, function, customer group, etc. Information related to the category of the merchandise may include information related to the large category, medium category, and small category to which the merchandise belongs. The large category may correspond to a relatively large classification category, such as food, clothing, medicine, beauty-related products, electrical appliances, or daily necessities, etc. The medium category may correspond to a classification category that further classifies the large category into two or more groups. In the case where the large category is electrical appliances, examples of the medium category may include vacuum cleaners, washing machines, refrigerators, video devices, lighting devices, information terminals, and air conditioners. The small category may correspond to a classification category that further classifies the medium category into two or more groups. In the case where the medium category is a washing machine, examples of the small category may include the washing capacity of the washing machine and the manufacturer of the washing machine.

[0056] In the present embodiment, the information generation unit F1 generates payment information before the completion of accounting (i.e., before the completion of the settlement process). That is, the information generation unit F1 generates payment information at any time point when the store device 10 as a POS terminal (see Figure 3 ) sequentially optically reads merchandise information related to one or more merchandise, or more preferably at the time point when the store device 10 reads the merchandise information related to the last merchandise. The information generation unit F1 sends the generated payment information to the server device 20 via the communication unit 11. In the present embodiment, the information generation unit F1 associates the payment information with the identification information (customer ID) of the customer (target person H1), and then sends the payment information to the server device 20.

[0057] The start command unit F2 outputs a command to start acquiring information (biological information) of the customer (target person H1) that the evaluation unit F14 is to use for performing the evaluation of the cognitive function. More specifically, the start command unit F2 causes the microphone of the voice acquisition unit 13 to start operating according to the acquisition command received from the server device 20 (described later) to convert the sound including the voice emitted by the customer (target person H1) into voice data. Then, the voice acquisition unit 13 causes the communication unit 11 to send the voice data to the server device 20.

[0058] As an example, after the store device 10 receives an acquisition command and then starts the voice collection operation of the microphone, the voice data can be any voice data autonomously emitted by the target person H1. The voice of the target person H1 collected by the microphone may include content related to payment or may be unrelated to payment. Optionally, the voice data can be the voice data emitted by the target person H1 by loudly reading out a prescribed fixed phrase.

[0059] As Figure 1 shown, the server device 20 includes a communication unit 21, a processing unit 22, and a storage unit 23.

[0060] The communication unit 21 is a communication interface. The communication unit 21 is a communication interface that can be connected to the telecommunication line NT1 and has a function of communicating with another device via the telecommunication line NT1 (see Figure 2 ). Therefore, the server device 20 is configured to communicate with the store device 10 via the telecommunication line NT1. In addition, the server device 20 is configured to communicate with the terminal device 30 via the telecommunication line NT1. The communication unit 21 can communicate with the store device 10 and the terminal device 30 using the same communication protocol or different communication protocols respectively. The storage unit 23 is a device for internally storing information. The storage unit 23 may include a read-only memory (ROM), a random access memory (RAM), or an EEPROM, etc.

[0061] The processing unit 22 may include, for example, a computer system including one or more processors (microprocessors) and one or more memories. The computer system performs the functions of the processing unit 22 by causing one or more processors to execute one or more programs (applications) stored in one or more memories.

[0062] The processing unit 22 is configured to perform overall control of the server device 20, that is, control operations of the communication unit 21 and the storage unit 23. Additionally, as Figure 1 shown, the processing unit 22 includes an information acquisition unit F11, a judgment unit F12, a biometric information acquisition unit F13, an evaluation unit F14, an evaluation result recording unit F15, and a notification unit F16. Note that the information acquisition unit F11, the judgment unit F12, the biometric information acquisition unit F13, the evaluation unit F14, the evaluation result recording unit F15, and the notification unit F16 represent the functions to be achieved by the processing unit 22, rather than physical components. In short, the server device 20 includes an information acquisition unit F11, an evaluation unit F14, and a judgment unit F12.

[0063] The information acquisition unit F11 acquires the payment information generated by the information generation unit F1 of the store device 10 via the communication unit 21. The information acquisition unit F11 associates the acquired payment information with the identification information (customer ID) of the customer, and enables the storage unit 23 to record the payment information. That is, the evaluation system 100 according to the present embodiment includes the information acquisition unit F11, and the information acquisition unit F11 is configured to acquire payment information related to the remuneration that the target person H1 (customer) should pay for receiving the service.

[0064] The determination unit F12 determines whether it is necessary to evaluate the cognitive function of the target person H1 (customer) by using the acquisition of the payment information as a trigger. In the present embodiment, the determination unit F12 determines whether it is necessary to evaluate the cognitive function of the target person H1 by processing the payment information of the target person H1 recorded in the storage unit 23. That is, the determination unit F12 determines whether it is necessary to evaluate the cognitive function based on the content of the acquired payment information.

[0065] In the present embodiment, the payment information (used by the determination unit F12 to determine whether it is necessary to evaluate the cognitive function) includes information related to the amount as the remuneration.

[0066] The determination unit F12 determines that it is necessary to evaluate the cognitive function, for example, when it is found that the amount is greater than or equal to a specified threshold. The amount can be the price (unit price) of one item, or the total price of two or more items. The threshold can be appropriately set by the target person H1 himself / herself, the family member of the target person H1, or the guardian of the target person H1 using the terminal device 30.

[0067] In the present embodiment, the payment information (used by the determination unit F12 to determine whether it is necessary to evaluate the cognitive function) further includes information related to the combination of two or more items acquired. In addition, the payment information further includes information related to the quantity of the acquired items.

[0068] That is, for example, when a person purchases two or more items, the determination unit F12 determines whether it is necessary to evaluate the cognitive function based on the combination of two or more items to be purchased. The "combination of two or more items to be purchased" mentioned herein may include the quantity of two or more items to be purchased.

[0069] For example, when the determination unit F12 finds that the combination of two or more items to be purchased is absurd (unreasonable), it determines that an evaluation of the cognitive function should be required. For example, when the determination unit F12 finds that two or more non-consumable supplies belonging to the same middle category (or the same small category) are purchased at one time (or within a short period of time), more specifically, when it finds that ten refrigerators are purchased at the same time, or when it finds that liquid crystal TVs, organic electroluminescence (EL) TVs, plasma TVs, and rear projection TVs of the same size are purchased at the same time, it determines that the combination of the items to be purchased should be absurd. In addition, when the determination unit F12 finds that the relationship between two or more items that are supposed to be used simultaneously is absurd, more specifically, when it finds that clothing of different sizes (for example, a small-sized top and an extra-large-sized bottom) is purchased at the same time, it determines that the combination of the items to be purchased should be absurd. Information related to the reference combination of items that may be absurd (unreasonable) is pre-recorded in the storage unit 23.

[0070] (The payment information (used by the determination unit F12 to determine whether an evaluation of the cognitive function of the target person H1 is required)) can be payment information related to a single payment. In other words, the determination unit F12 can determine whether to utilize the evaluation of the evaluation unit F14 based on the payment information related to a single payment.

[0071] Optionally, (the payment information (used by the determination unit F12 to determine whether an evaluation of the cognitive function of the target person H1 is required)) can be the history of payment information within a specified time period (for example, one day, two days, three days, one week, two weeks, one month, two months, three months, six months, or one year, etc.). In other words, the determination unit F12 can determine whether to utilize the evaluation of the evaluation unit F14 based on the history of payment information within a specified time period.

[0072] Needless to say, the determination unit F12 can make a determination regarding whether to utilize the evaluation of the evaluation unit F14 based on the payment information related to a single payment and based on the history of payment information within a specified time period.

[0073] When the determination unit F12 determines that an evaluation of the cognitive function should be required, the biological information acquisition unit F13 acquires the biological information of the target person H1 (customer). In this embodiment, the biological information of the target person H1 is voice data as information related to the voice emitted by the target person H1. Therefore, the biological information acquisition unit F13 includes a voice data acquisition unit F131 for acquiring voice data.

[0074] When the determination unit F12 determines that an evaluation of cognitive function is required, the voice data acquisition unit F131 enables the communication unit 21 to send an acquisition command to the store device 10. The voice data acquisition unit F131 acquires, via the communication unit 21, voice data sent from the store device 10 as a response to the acquisition command. The voice data acquisition unit F131 associates the acquired voice data with the target person H1, and enables the storage unit 23 to record the voice data in association with the target person H1.

[0075] Briefly, the evaluation system 100 according to the present embodiment includes a voice data acquisition unit F131. When the determination unit F12 determines that an evaluation by the evaluation unit F14 is required, the voice data acquisition unit F131 acquires the voice data of the target person H1.

[0076] When the determination unit F12 determines that an evaluation of cognitive function is required, the evaluation unit F14 evaluates the cognitive function of the target person H1 (customer) based on the biological information of the target person H1. In the present embodiment, the evaluation unit F14 evaluates the cognitive function of the target person H1 by processing the voice data acquired by the voice data acquisition unit F131 and recorded in the storage unit 23.

[0077] In the present embodiment, the evaluation unit F14 uses the features (feature amounts) extracted from the voice data to evaluate the cognitive function of the target person H1.

[0078] The feature amounts to be used for the evaluation of the cognitive function of the target person H1 may include amounts related to the first formant frequency or the second formant frequency of a vowel sound in the syllables included in the voice of the target person H1 represented by the voice data. The first formant frequency is the frequency corresponding to the lowest frequency peak among the multiple frequency peaks included in the voice emitted by a person. The second formant frequency is the frequency corresponding to the second lowest frequency peak among the multiple frequency peaks included in the voice emitted by a person.

[0079] The feature amounts to be used for the evaluation of the cognitive function of the target person H1 may include the difference between the sound pressure of a consonant sound and the sound pressure of the vowel sound following the consonant sound, both in the open syllables included in the voice of the target person H1 represented by the voice data.

[0080] The feature amounts to be used for the evaluation of the cognitive function of the target person H1 may include the change in the differences, each between the sound pressure of a consonant sound and the sound pressure of the vowel sound following the corresponding consonant sound among the vowel sounds in the multiple open syllables included in the voice of the target person H1 represented by the voice data.

[0081] Note that, for details regarding the feature quantity of the voice of the target person H1 to be used by the evaluation unit F14 for evaluating the cognitive function of the target person H1, refer to, for example, Japanese Patent No. 6337362.

[0082] The evaluation unit F14 outputs an evaluation result related to the cognitive function of the target person H1. This evaluation result is represented, for example, by a numerical value indicating the degree of decline in the cognitive function of the target person H1. The evaluation unit F14 can represent the obtained evaluation result of the cognitive function using, for example, a numerical value indicating a corresponding stage among two or more predetermined stages (for example, the second stage among five stages).

[0083] The evaluation result recording unit F15 associates the evaluation result of the cognitive function of the target person H1 obtained by the evaluation unit F14 with the payment information, and records this evaluation result in the storage unit 23. In other words, the evaluation system 100 according to the present embodiment includes an evaluation result recording unit F15, which is configured to associate the evaluation result related to the cognitive function of the target person H1 obtained by the evaluation unit F14 with the payment information, and record the evaluation result in association with the payment information.

[0084] The notification unit F16 notifies the store device 10 and the terminal device 30 of result information related to the evaluation result using the evaluation unit F14. For example, when it is found that the numerical value indicating the degree of decline in the cognitive function evaluated by the evaluation unit F14 is greater than a specified threshold (hereinafter sometimes referred to as "when it is found that the target person H1 has a high possibility of having dementia"), the notification unit F16 notifies the store device 10 and the terminal device 30 of the result information. The notification unit F16 can notify the store device 10 and the terminal device 30 of the result information regardless of the content of the evaluation result.

[0085] The result information (notified by the notification unit F16 to the store device 10 and the terminal device 30) can be the evaluation result itself (for example, a numerical value) obtained by the evaluation unit F14 or a form different from a numerical value.

[0086] In the present embodiment, when it is found that the target person H1 has a high possibility of having dementia, the notification unit F16 notifies the store device 10 of sales attention information. The sales attention information includes, for example, information indicating that the target person H1 has a high possibility of having dementia. The sales attention information can include information for instructing cancellation of the settlement process of the commodity.

[0087] As described above, sending the sales attention information to the store device 10 can prompt the salesperson operating the store device 10 in the store 1 to stop selling the commodity (that is, stop the settlement process). Therefore, the evaluation system 100 can prevent the target person H1 from purchasing unnecessary commodities.

[0088] In addition, when the notification unit F16 detects that the target person H1 has a high likelihood of having dementia, it also notifies the terminal device 30 of cancellation information. The cancellation information may include, for example, one or more pieces of information selected from the following: payment information; information related to the time limit for permitting the return of goods; and information related to the procedures required for returning goods.

[0089] For example, in Japan, there is a system (so-called "cooling-off period system") where a buyer can unconditionally revoke a purchase order or cancel a contract within a certain period of time for certain contracts based on the law without giving an explanation. The information related to the procedures required for returning goods may include information related to the cooling-off period system. Examples of laws related to the cooling-off period system include the Specific Commercial Transactions Act. In addition, the information related to the procedures required for returning goods may include information for applying to cancel a contract or expressing an intention to accept a contract based on the Consumer Contract Act. Optionally, if the seller independently sets a time limit for permitting the return of goods, the information related to the procedures required for returning goods may include information related to the time limit.

[0090] As described above, notifying the terminal device 30 of the cancellation information can increase the chance that even after the settlement process is completed despite the sales caution information being sent to the store device 10, the user of the terminal device 30 can cancel the settlement process (payment). That is, unnecessary goods purchased by the target person H1 can be cancelled.

[0091] The server device 20 can notify the terminal device 30 of the cancellation information after receiving a notification that the settlement process is completed from the store device 10 (i.e., after the settlement process is completed at Store 1 and the payment is also completed).

[0092] In short, the evaluation system 100 according to the present embodiment includes a notification unit F16. The notification unit F16 is configured to notify at least one selected from the target person H1 himself, the family members of the target person H1, and the guardians of the target person H1 of cancellation information for canceling payment when the value representing the degree of decline in cognitive function evaluated by the evaluation unit F14 is greater than a specified threshold.

[0093] In the above example, the notification unit F16 notifies the result information to both the store device 10 and the terminal device 30. However, this is merely an example and should not be construed as restrictive. The notification unit F16 may notify the result information only to the store device 10 or the terminal device 30. Note that the notification unit F16 preferably notifies the result information to at least the terminal device 30.

[0094] As described above, the terminal device 30 is an information terminal. As an example, the terminal device 30 can be implemented as a mobile terminal, a mobile phone, or a personal computer. The mobile terminal can be, for example, a smart phone or a tablet terminal. The terminal device 30 presents the cancellation information received from the server device 20. In the present embodiment, it is assumed that the terminal device 30 is a tablet terminal (see Figure 2 ).

[0095] As Figure 1 shown, the terminal device 30 includes a communication unit 31, a display unit 32, an operation unit 33, and a processing unit 34. The terminal device 30 in the present embodiment further includes a call unit 35.

[0096] The communication unit 31 is a communication interface. The communication unit 31 is a communication interface that can be connected to the telecommunication line NT1 and has a function of communicating with other devices via the telecommunication line NT1. Therefore, the terminal device 30 is configured to communicate with the server device 20 via the telecommunication line NT1.

[0097] The display unit 32 displays information based on the data received at the communication unit 31 and the like. The display unit 32 includes, for example, a liquid crystal display (LCD) or an organic EL display. The display unit 32 displays, for example, the result information (cancellation information) received from the server device 20.

[0098] The operation unit 33 accepts an operation input from the user and then outputs a signal corresponding to the accepted operation input. In the present embodiment, since it is assumed that the terminal device 30 is a general tablet terminal, the display unit 32 and the operation unit 33 are integrally formed as a touch panel display. In the case where the terminal device 30 as a touch panel display detects an operation (for example, a tap operation, a swipe operation, or a drag operation) on an object such as a button on each screen displayed by the display unit 32, it is determined that the object (such as a button) has been operated. That is, in addition to displaying various information, the display unit 32 and the operation unit 33 serve as a user interface for accepting an operation input from the user.

[0099] The call unit 35 includes a speaker and a microphone. The microphone converts the sound including the voice emitted by the user into voice data (voice signal) and then outputs the voice data to the outside via the communication unit 31. The speaker converts the voice data (voice signal) received from the outside via the communication unit 31 into voice (sound) and then outputs the voice.

[0100] The processing unit 34 is configured to perform overall control of the terminal device 30, that is, control operations of the communication unit 31, the display unit 32, the operation unit 33, and the call unit 35. The processing unit 34 may include, for example, a computer system including one or more processors (microprocessors) and one or more memories. The computer system performs the functions of the processing unit 34 by causing one or more processors to execute one or more programs (applications) stored in one or more memories. In the present embodiment, one or more programs to be executed by one or more processors are pre-stored in one or more memories of the processing unit 34. However, this is merely an example and should not be construed as restrictive. One or more programs may also be distributed in a non-transitory storage medium such as a memory card, or downloaded via a telecommunication line such as the Internet.

[0101] (2.2) Operations

[0102] Next, an exemplary operation related to how the evaluation system 100 according to the present embodiment operates will be briefly described with reference to Figure 4 .

[0103] A customer appropriately picks up one or more items displayed in Store 1 and requests a salesperson to perform a settlement process at the payment location in Store 1 (see Figure 3 ). The salesperson enables the store device 10 to read product information according to the request. The store device 10 generates payment information based on the read product information. The store device 10 sends the generated payment information to the server device 20, and the server device 20 obtains the payment information accordingly (information acquisition process S1). When acquiring the payment information, the server device 20 determines whether it is necessary to evaluate the cognitive function based on the acquired payment information (judgment process S2).

[0104] When determining whether it is necessary to evaluate the cognitive function (step S3), if the server device 20 determines that evaluation is not required (when answering "no" in step S3), it sends the judgment result to the store device 10 and / or the terminal device 30 as needed and ends the operation. On the other hand, if the server device 20 determines that evaluation is required (when answering "yes" in step S3), it enables the communication unit 21 to send an acquisition command to the store device 10. The store device 10 acquires biometric information (here, voice data of the target person) of the target person H1 by receiving the acquisition command and recording the voice of the target person H1 (biometric information acquisition process S4). Then, the store device 10 sends the acquired biometric information to the server device 20.

[0105] When the server device 20 receives biometric information, it evaluates the cognitive function of the target person H1 by processing the received biometric information (evaluation process S5).

[0106] In the evaluation of the cognitive function (in step S6), if a result indicating that the cognitive function of the target person H1 is high (i.e., the possibility that the target person has dementia or MCI is low) is obtained (if the answer in step S6 is "no"), the server device 20 sends the evaluation result to the store device 10 and / or the terminal device 30 as needed and ends the operation. On the other hand, if a result indicating that the cognitive function of the target person H1 has declined (i.e., the possibility that the target person has dementia or MCI is high) is obtained (if the answer in step S6 is "yes"), the server device 20 notifies the store device 10 and / or the terminal device 30 of the result information (notification process S7). Here, as described above, the result information notified by the server device 20 to the terminal device 30 may include cancellation information.

[0107] When the store device 10 and / or the terminal device 30 receives the result information, the salesperson or user of the terminal device 30 can take appropriate measures based on the result information.

[0108] As described above, the evaluation system 100 according to the present embodiment uses the acquisition of payment information as a trigger to judge the cognitive function of the target person H1 as needed, and in addition, the notification unit F16 notifies the store device 10 and / or the terminal device 30 of the result information as needed. Therefore, the evaluation system 100 can reduce the frequency of execution of notifications. Therefore, the evaluation system 100 can achieve improved convenience. In addition, when the evaluation unit F14 determines that the cognitive function of the target person H1 has declined during shopping, the notification of cancellation information is executed. Therefore, the evaluation system 100 can increase the opportunity for the person who receives the notification to cancel the purchase, and as a result, improved convenience can be achieved.

[0109] (3) Modification example

[0110] Various embodiments of the present invention are not limited to the above-described exemplary embodiments. The exemplary embodiments can be easily modified in various forms according to design choices or any other factors as long as the object of the present invention can be achieved. Functions similar to those of the evaluation system 100 according to the exemplary embodiment can also be implemented as, for example, an evaluation method, a computer program, or a non-transitory storage medium storing the computer program.

[0111] An evaluation method according to one aspect includes information acquisition processing, evaluation processing, and determination processing. The information acquisition processing includes: acquiring payment information related to the remuneration to be paid by the target person H1 for receiving the service. The evaluation processing includes: evaluating the cognitive function of the target person H1. The determination processing includes: determining whether it is necessary to evaluate the cognitive function of the target person H1 by using the acquisition of the payment information as a trigger.

[0112] A (computer) program according to one aspect is a computer program designed to cause one or more processors to execute the above evaluation method.

[0113] Hereinafter, modifications of the above-described exemplary embodiments will be listed. The modifications to be described below can be appropriately combined and employed.

[0114] The evaluation system 100 according to the present invention includes, for example, a computer system in the server device 20. The computer system may include a processor and a storage element as main hardware components. The functions of the server device 20 can be performed by causing the processor to execute a program stored in the memory of the computer system. The program may be pre-stored in the storage element of the computer system. Optionally, the program may also be downloaded via a telecommunications line or distributed after being recorded on some non-transitory storage medium such as a memory card, an optical disc, or a hard disk drive (any of which is readable by the computer system). The processor of the computer system can be implemented as a single or multiple electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). As used herein, "integrated circuits" such as ICs or LSIs are referred to by different names according to their degree of integration. Examples of integrated circuits include system LSIs, very large-scale integrated circuits (VLSIs), and ultra-large-scale integrated circuits (ULSIs). Optionally, a field programmable gate array (FPGA) to be programmed after manufacturing the LSI or a reconfigurable logic device that allows reconfiguration of the connections or circuit sections inside the LSI may also be employed as the processor. These electronic circuits can be integrated together on a single chip or distributed over multiple chips, either of which is appropriate. These multiple chips can be integrated together in a single device or distributed over multiple devices, without limitation. As used herein, a "computer system" includes a microcontroller including one or more processors and one or more memories. Thus, the microcontroller is also implemented as a single or multiple electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0115] In addition, the multiple functions of the evaluation system 100 are integrated together in a single housing, but this is not a necessary structure of the evaluation system 100. Optionally, the multiple functions of the evaluation system 100 can be distributed among multiple different housings. Also optionally, at least some functions of the evaluation system 100 (e.g., some functions of the server device 200) can also be implemented as a cloud computing system.

[0116] Conversely, at least some functions of the evaluation system 100 that are distributed among multiple devices in the above-described exemplary embodiment can be integrated together in a single housing. For example, some functions of the evaluation system 100 that are distributed to the server device 20 and the store device 10 can be integrated together in a single housing.

[0117] (3.1) First modification example

[0118] In the above-described exemplary embodiment, the determination unit F12 determines whether it is necessary to utilize the evaluation of the evaluation unit F14 for all customers. However, the determination unit F12 of the evaluation system 100 can determine whether it is necessary to utilize the evaluation of the evaluation unit F14 only for a pre-registered target person H1 (one or more). In this case, as Figure 5 shown, the server device 20 can further include a target designation unit F17.

[0119] In this modification example, for example, the storage unit 23 of the server device 20 records information related to the pre-registered target person H1 (e.g., name, age, and gender) and voiceprint information as information related to the voiceprint of the pre-acquired target person H1. The information (name, age, and gender) and the voiceprint information are recorded in the storage unit 23 in association with each other. The information related to the target person H1 (e.g., name, age, and gender) and the voiceprint information of the target person H1 are registered, for example, by a user (the target person H1 himself / herself, his / her family member, or his / her guardian) using the terminal device 30 to input their information, and then the terminal device 30 sending the input information to the server device 20. That is, the evaluation system 100 in this modification example (i.e., the processing unit 22 of the server device 20) includes a registration unit for registering the target person H1.

[0120] In this modification example, for example, the store device 10 sends payment information together with the voice data of the customer acquired by the voice acquisition unit 13 to the server device 20. When the server device 20 receives the payment information and the voice data from the store device 10, it enables the target designation unit F17 to compare the voice data with the voiceprint information recorded in the storage unit 23 to determine whether the customer is the target person H1 and to designate the target person H1. Therefore, the server device 20 can determine whether it is necessary to utilize the evaluation of the evaluation unit F14 only when the customer is a pre-registered target person H1.

[0121] Briefly, the evaluation system 100 according to this modification example further includes a target specifying unit F17. The target specifying unit F17 is configured to specify the target person H1 based on voice data that is information related to the voice emitted by the target person H1 and voiceprint information that is information related to the voiceprint of the target person H1 acquired in advance.

[0122] This is merely an example and should not be construed as restrictive. The server device 20 can determine whether a customer is the registered target person H1 based on the customer ID added to the ID-POS data.

[0123] (3.2) Second modification example

[0124] In the above-described exemplary embodiment, the voice acquisition unit 13 is provided for the store device 10. However, the voice acquisition unit 13 can be provided for a device other than the store device 10 (for example, an information terminal such as a mobile terminal, a mobile phone, or a personal computer carried by the target person H1).

[0125] Similarly in this modification example, as in the first modification example, information related to the target person H1 (for example, name, age, and gender) is registered in the server device 20 in advance. In this modification example, the information related to the target person H1 further includes the identification information of the information terminal carried by the target person H1.

[0126] When the determination unit F12 determines that the evaluation by the evaluation unit F14 is required, the biometric information acquisition unit F13 of the server device 20 sends an acquisition command to the information terminal to acquire voice data from the information terminal. The evaluation unit F14 processes the acquired voice data to evaluate the cognitive function of the target person H1.

[0127] The information terminal in this modification example can be the terminal device 30 in the above-described exemplary embodiment.

[0128] (3.3) Third modification example

[0129] In this modification example, as Figure 6 shown, all the functions of the evaluation system 100 are integrated in the terminal device 30 together. That is, the processing unit 34 of the terminal device 30 in this modification example has the functions of the information acquisition unit F11, the determination unit F12, the biometric information acquisition unit F13, the evaluation unit F14, and the evaluation result recording unit F15. Briefly, in this modification example, the cognitive function of the target person H1 is evaluated only by the terminal device 30 without going through the server device 20.

[0130] The terminal device 30 may include a voice acquisition unit 13, and the processing unit 34 of the terminal device 30 may have the functions of an information generation unit F1 and a start command unit F2.

[0131] Optionally, the terminal device 30 may be the store device 10.

[0132] (3.4) Other modification examples

[0133] In a modification example, the store device 10 may include an acceptance unit for accepting an operation related to whether to send payment information to the server device 20. For example, the store device 10 may send payment information to the server device 20 only when the salesperson in store 1 operates the acceptance unit.

[0134] In a modification example, store 1 is not limited to a retail store and may be a virtual store. In this case, for example, a phone or personal computer operated by a customer (target person H1) may send voice data of the target person H1 to the server device 20 according to an acquisition command received from the server device 20.

[0135] In a modification example, regardless of the content of the payment information, the determination unit F12 may enable the evaluation unit F14 to evaluate the cognitive function of the target person H1. That is, the determination unit F12 may determine whether it is necessary to use the evaluation unit F14 to evaluate the cognitive function of the target person H1 only by using the acquisition of payment information as a trigger.

[0136] In a modification example, the biological information (used by the evaluation unit F14 to evaluate the cognitive function) is not limited to the voice of the target person H1. The biological information (used by the evaluation unit F14 to evaluate the cognitive function) may be information related to the eye movement of the target person H1 or information related to the walking of the target person H1, and this information may be acquired by an imaging unit (for example, a camera). For example, the imaging unit may be set for the store device 10 or the information terminal carried by the target person H1.

[0137] In a modification example, the information acquisition unit F11 may receive payment information after the settlement process in the store device 10 is completed. In this case, the determination unit F12 determines whether it is necessary to use the evaluation of the evaluation unit F14 at an appropriate time point after the settlement process is completed. When the determination unit F12 determines that evaluation is required, the biological information acquisition unit F13 enables the information terminal carried by the target person H1 to acquire the biological information of the target person H1. The evaluation unit F14 uses the biological information acquired by the information terminal to evaluate the cognitive function of the target person H1. In this case, this system cannot prevent the target person H1 from making unnecessary purchases, but can cancel the purchases made.
