[0010] Hereinafter, examples of embodiments of the present invention will be specifically described with reference to the drawings. In each of the referenced drawings, the same parts are denoted by the same reference numerals, and redundant descriptions relating to the same parts are omitted as a general rule. In addition, in this specification, for the sake of simplification of the description, symbols or reference numerals that refer to information, signals, physical quantities, functional parts, circuits, elements, or components may be indicated, and the names of the information, signals, physical quantities, functional parts, circuits, elements, or components corresponding to such symbols or reference numerals may be omitted or abbreviated.

[0011] This diagram shows a schematic overall configuration of a system SYS according to an embodiment of the present invention. The system SYS comprises a plurality of terminal devices 100 and a system management device 200. As will become clear in detail later, the system management device 200 has a function to evaluate the quality of various services. For this reason, the system management device 200 can also be said to be an example of a service evaluation device, and the system SYS can also be called a service evaluation system.

[0012] Each terminal device 100 and the system management device 200 are wirelessly connected via a predetermined communication network NET, and each terminal device 100 and the system management device 200 can communicate bidirectionally with each other via the communication network NET. The communication network NET includes all or part of the following: the Internet, a wireless LAN (Local Area Network), and a short-range wireless communication line. The wireless LAN may be, for example, compliant with Wi-Fi®. The short-range wireless communication line may be, for example, compliant with Bluetooth®.

[0013] In Figure 1, the symbol "PS" represents a person acting as a user of terminal device 100. A user is a person who operates and possesses terminal device 100. For example, an electronic device such as a smartphone, tablet, or personal computer can be used as terminal device 100.

[0014] In Figure 1, the symbol "BB" represents an information acquisition device (a device for acquiring biological information). Each information acquisition device BB is attached to any person PS and acquires the biological information of that person PS. The information acquisition device BB is attached to a specific part of the person PS. The specific part is, for example, the vicinity of the wrist. That is, the information acquisition device BB may be a wristwatch-type device attached to the person PS near the wrist. However, the specific part is not limited to the vicinity of the wrist, and may be the chest, neck, leg, etc.

[0015] As shown in Figure 2, it is assumed below that a total of n terminal devices 100, namely terminal devices 100[1] to 100[n], are operated within the system SYS. n is an integer greater than or equal to 2, and a very large value such as 1,000,000 is assumed. The user of terminal device 100[i] is specifically referred to as person PS[i]. Here, i represents any natural number less than or equal to n. Person PS[i] operates and possesses terminal device 100[i]. The information acquisition device BB corresponding to person PS[i] is specifically referred to as information acquisition device BB[i]. Information acquisition device BB[i] is attached to person PS[i] and acquires the biometric information of person PS[i]. In this way, information acquisition device BB[i] and terminal device 100[i] are associated with person PS[i]. Information acquisition device BB[i] and terminal device 100[i] are wirelessly connected to each other in a manner that enables bidirectional communication via a short-range wireless communication line compliant with Bluetooth® or the like.

[0016] Figure 3 shows a schematic block diagram of one terminal device 100. In system SYS, any two terminal devices 100 may be of different types. That is, for example, any two terminal devices 100 may be of different types of smartphones. Or, for example, one terminal device 100 may be a smartphone and the other terminal device 100 may be a personal computer. However, in the following description, it will be assumed that each terminal device 100 has the configuration shown in Figure 3. That is, each terminal device 100 in system SYS shall be equipped with the parts referenced by reference numerals 110, 120, 130, 140, 150, 160 and 170.

[0017] The terminal control unit 110 is equipped with a arithmetic processing unit 110a, including an MPU (Micro Processing Unit) and a GPU (Graphics Processing Unit), as hardware resources, and comprehensively controls the operation of each part of the terminal device 100. In the following description, any operation and processing performed by the terminal control unit 110 may be understood as operation and processing performed by the arithmetic processing unit 110a.

[0018] Memory 120 includes non-volatile memory such as ROM (Read-only memory) or flash memory, and volatile memory such as RAM (Random Access Memory). All or part of memory 120 may be memory built into the terminal control unit 110. Program PG1 is stored in memory 120. The arithmetic processing unit 110a can realize the functions of program PG1 by executing program PG1. In the following description, any operation and processing performed by the terminal control unit 110 may be understood as operation and processing performed by the arithmetic processing unit 110a. Program PG1 may consist of multiple programs, including programs PG1a and PG1b. If the arithmetic processing unit 110a is provided with multiple MPUs, the multiple programs within program PG1 may be executed by multiple MPUs.

[0019] The communication processing unit 130 enables bidirectional communication between the terminal device 100 and the other device. The other device of the terminal device 100 includes the system management device 200 and the information acquisition device BB. The communication processing unit 130 comprises a transmission unit 131 that transmits arbitrary information to the other device and a reception unit 132 that receives information transmitted from the other device. In the following, descriptions of the communication processing unit 130, transmission unit 131 and reception unit 132 may be omitted, but in the terminal device 100, the transmission of information to the other device is realized using the communication processing unit 130 (transmission unit 131), and the reception of information from the other device is realized using the communication processing unit 130 (reception unit 132).

[0020] Camera 140 captures subjects within its shooting area and generates image information of the images within the shooting area (hereinafter referred to as captured images). The generated image information is sent to the terminal control unit 110. Camera 140 sequentially captures images at a predetermined frame period, thereby acquiring multiple captured images arranged in chronological order. A moving image is formed from these multiple captured images arranged in chronological order.

[0021] The GPS processing unit 150 detects the position of the terminal device 100 (the current location of the terminal device 100) by receiving signals from multiple GPS satellites that form the GPS (Global Positioning System). The detected position of the terminal device 100 is called the terminal position, and the information representing the terminal position is called terminal position information. The terminal position information is sent from the GPS processing unit 150 to the terminal control unit 110. The terminal position of a certain terminal device 100 can be considered to represent the current location of the user of the terminal device 100.

[0022] The date and time information acquisition unit 160 acquires date and time information indicating the current date and time and sends it to the terminal control unit 110. The date and time information acquisition unit 160 may also acquire date and time information from other devices (not shown) via the communication network NET.

[0023] The interface unit 170 is a man-machine interface between the terminal device 100 and the user of the terminal device 100, outputting arbitrary information to the user of the terminal device 100 and receiving arbitrary information from the user of the terminal device 100. The interface unit 170 includes a display screen 171, an operation unit 172, a microphone 173, and a speaker 174. The display screen 171 is made up of a liquid crystal display panel or the like and displays an arbitrary image under the control of the terminal control unit 110. The operation unit 172 accepts arbitrary operation input from the user of the terminal device 100. The display screen 171 and the operation unit 172 may constitute a touch panel, and operations on the operation unit 172 may also be operations on the touch panel. The microphone 173 picks up ambient sound and converts the picked-up sound into an electrical signal. The speaker 174 outputs an arbitrary sound under the control of the terminal control unit 110.

[0024] Figure 4 shows the overall configuration of the system management device 200. The system management device 200 comprises a management control unit 210, a memory 220, and a communication processing unit 230. The system management device 200 is composed of one or more computer devices connected to a communication network NET. The system management device 200 may also be formed using cloud computing.

[0025] The management control unit 210 includes a processing unit 210a, which includes an MPU and a GPU, as hardware resources.

[0026] Memory 220 includes non-volatile memory such as ROM or flash memory, and volatile memory such as RAM. All or part of memory 220 may be memory built into the management control unit 210. Program PG2 is stored in memory 220. In the management control unit 210, the functions of the management control unit 210 (including the function blocks described later) may be realized by the arithmetic processing unit 210a executing program PG2 stored in memory 220. Program PG2 here may contain multiple programs. In the following description, any operation and processing performed in the management control unit 210 may be understood as operation and processing performed in the arithmetic processing unit 210a. Multiple MPUs may be provided in the management control unit 210, and the functions of the management control unit 210 (including the function blocks described later) may be realized by the execution of multiple programs on these multiple MPUs.

[0027] The communication processing unit 230 enables bidirectional communication with the other device via the communication network NET. For the system management device 200, the other devices include each terminal device 100. The communication processing unit 230 includes a transmitting unit 231 that transmits arbitrary information to the other device and a receiving unit 232 that receives information transmitted from the other device. In the following, descriptions of the communication processing unit 230, transmitting unit 231, and receiving unit 232 may be omitted, but in the system management device 200, the transmission of information to the other device is achieved using the communication processing unit 230 (transmitting unit 231), and the reception of information from the other device is achieved using the communication processing unit 230 (receiving unit 232).

[0028] In terminal device 100 (see Figure 3), program PG1a is an application program capable of searching for, reserving, and settling payments for various services. These services include transportation services. Transportation services are services in which any person is transported by any means of transport over any distance. Public transportation is assumed as the means of transport. Transportation includes vehicles, aircraft, and ships. Vehicles may be taxis and buses traveling on roads, or trains (electric trains or steam locomotives) traveling on railway tracks.

[0029] Program PG1a is a program for realizing "Mobility as a Service". The arithmetic processing unit 110a realizes "Mobility as a Service" by executing program PG1a. However, the entire "Mobility as a Service" is realized through the cooperation of various devices connected to the communication network NET.

[0030] The arithmetic processing unit 110a executes the program PG1a, enabling the arithmetic processing unit 110a to perform search processing, reservation processing, and settlement processing. Search processing, reservation processing, and settlement processing are performed based on operations received from the user of the terminal device 100 via the interface unit 170.

[0031] A designated person PS is referred to as the designated person PS, and the terminal device 100 that the designated person PS uses as a user is referred to as the designated terminal device 100. Assuming that the designated person PS wishes to travel from an arbitrary starting point to an arbitrary destination using public transportation, the search, reservation, and payment processes on the designated terminal device 100 will be described. When the designated person PS inputs search specification information representing the above-mentioned wish to the designated terminal device 100 through the interface unit 170, the search process searches for and identifies one or more routes for travel from the starting point to the destination. The one or more searched and identified routes are displayed on the display screen 171. The route search itself is performed by a search device (not shown) connected to the communication network NET. Therefore, the entire search process can be considered to be realized through the cooperation of the designated terminal device 100 and the search device.

[0032] When the person of interest PS selects one of the displayed routes and inputs a reservation instruction to the attention terminal device 100, the reservation process is executed. In this reservation process, the use of transportation to transport the person of interest PS along the specified route is reserved (i.e., a contract is established that the person of interest PS will use said transportation). The reservation itself is executed by a reservation device (not shown) connected to the communication network NET. Therefore, the entire reservation process can be considered to be realized through the cooperation of the attention terminal device 100 and the reservation device.

[0033] Following the reservation instruction operation, when the person of interest PS inputs a payment instruction operation to the terminal device 100, payment processing is executed based on the payment information of the person of interest PS. In the payment processing, the fare for using the reserved transportation is settled. The payment information of the person of interest PS is the information necessary for settling the above fare and is associated with the person of interest PS (for example, credit card information, bank account information, or personal information for an electronic payment service). The payment itself is executed by a payment device (not shown) connected to the communication network NET. Therefore, it can be considered that the entire payment processing is realized through the cooperation of the terminal device 100 and the payment device.

[0034] The search, reservation, and payment processes described above assume that the services subject to these processes are transportation services. However, the services subject to these processes may include services other than transportation services. For example, facility services may be included in the services subject to these processes. Facility services are services in which facilities are used by any person. Examples of facilities include accommodations, restaurants, bathing facilities, and sports facilities. Here, we assume that facilities are those that can be reserved for use and require payment (fee payment) upon use.

[0035] This section describes the search, reservation, and payment processes related to facilities. The user PS inputs search specification information, indicating the conditions of the facility they wish to use, into the user terminal device 100 via the interface unit 170. The user terminal device 100 then displays one or more facilities that meet these conditions on the display screen 171 during the search process. When the user PS selects one of the displayed facilities and inputs a reservation instruction into the user terminal device 100, the reservation process is executed. This reservation process reserves the use of the specified facility (i.e., a contract is established for the user PS to use the facility). Following the reservation instruction, when the user PS inputs a payment instruction into the user terminal device 100, the payment process is executed based on the user PS's payment information. The payment process settles the fee for using the reserved facility.

[0036] Here, information entered by any person of interest PS into the terminal device 100 is referred to as user input information. User input information about person of interest PS includes information received by the terminal device 100 from person of interest PS during search processing, reservation processing, and payment processing. The user input information is transmitted from the terminal device 100 to the system management device 200 according to program PG1a, and is associated with person of interest PS by the management control unit 210.

[0037] Therefore, if the service subject to search, reservation, and payment processing is a transportation service, the management control unit 210 can recognize when, which mode of transportation, and from where to where the person of interest PS will travel. The person of interest PS will actually travel from the departure point to the destination point according to the results of the reservation they made. Furthermore, if the service subject to search, reservation, and payment processing is a facility service, the management control unit 210 can recognize when, which facility the person of interest PS will use. The person of interest PS will use the facility they reserved according to the results of the reservation they made.

[0038] In terminal device 100 (see Figure 3), program PG1b is an application program that works in cooperation with information acquisition device BB to collect and manage biometric information of person PS. By executing program PG1b, the arithmetic processing unit 110a can perform biometric information collection and biometric information management processing. The biometric information collection and management processing in terminal device 100 will now be explained.

[0039] Biometric information of the person of interest PS is acquired by an information acquisition device BB attached to the person of interest PS. Biometric information is acquired sequentially at predetermined intervals, and the acquired biometric information is transmitted from the information acquisition device BB to the target terminal device 100. In the biometric information collection process, the target terminal device 100 collects the received biometric information of the person of interest PS and stores it in memory 120. At this time, a timestamp information is generated based on the date and time information to identify when each piece of collected biometric information was obtained, and is added to the biometric information. The addition of timestamp information may also be performed by the information acquisition device BB.

[0040] In the biometric information management process, various information based on the biometric information stored in memory 120 is provided to the person of interest PS. For example, in the biometric information management process, the biometric information stored in memory 120 is displayed on the display screen 171 in chronological order, or statistical information of the biometric information stored in memory 120 is displayed on the display screen 171.

[0041] The biometric information stored in memory 120 through the biometric information collection process is transmitted from the attention terminal device 100 to the system management device 200, and associated with the person of interest PS in the management control unit 210. Therefore, the management control unit 210 can recognize the biometric information of the person of interest PS at each date and time. The transmission of biometric information to the system management device 200 may be performed according to program PG1a or program PG1b. Alternatively, biometric information may be transmitted directly from the information acquisition device BB to the system management device 200.

[0042] The biometric information of the person of interest PS is optional, as long as it is detectable information regarding the person of interest PS's physical functions. The biometric information of the person of interest PS includes, for example, all or part of the person of interest PS's pulse rate, body temperature, blood pressure, amount of sweat, blood oxygen saturation, and blood glucose level. The pulse rate in the biometric information of the person of interest PS includes, for example, all or part of the person of interest PS's pulse rate, pulse rhythm, and pulse magnitude.

[0043] Furthermore, all or part of the information acquisition device BB may be built into the terminal device 100. If the entire information acquisition device BB is built into the terminal device 100, all of the biological information will be acquired by the terminal device 100. If only a part of the information acquisition device BB is built into the terminal device 100, a portion of the biological information will be acquired by the terminal device 100, and the remaining portion of the biological information will be acquired by the information acquisition device BB.

[0044] In the following, unless otherwise specified, it is assumed that programs PG1a and PG1b are constantly being executed as resident programs by the arithmetic processing unit 110a in each of the terminal devices 100[1] to 100[n].

[0045] Furthermore, unless otherwise specified, it is assumed below that the services subject to search processing, reservation processing, and payment processing are primarily transportation services. Also, a service reservation by person PS[i] is defined as a reservation made using terminal device 100[i] through the functions of program PG1a.

[0046] Figure 5 shows a functional block diagram of the management control unit 210. The management control unit 210 comprises functional blocks F21 to F25. Functional blocks F21 to F25 may be realized by the execution of one or more programs in the arithmetic processing unit 210a. Multiple MPUs may be provided in the arithmetic processing unit 210a, and any multiple functional blocks (in this case, functional blocks F21 to F25) may be realized by the individual execution of multiple programs on these multiple MPUs. Functional blocks F21, F22, F23, F24, and F25 are the service utilization identification unit, analysis and evaluation unit, terminal feedback unit, matching unit, and service proposal unit, respectively. The functions of the matching unit F24 and the service proposal unit F25 will be explained in a later embodiment.

[0047] The service usage identification unit F21 identifies the service currently being used by each person PS based on the person PS's behavior information, and generates and outputs service usage information indicating the identified service. The behavior information of person PS[i] is information representing the content of person PS[i]'s actions at each time point. The behavior information of person PS[i] includes the user input information of person PS[i]. The user input information of person PS[i] includes information received by terminal device 100[i] from person PS[i] during search processing, reservation processing, and payment processing. User input information is transmitted from each terminal device 100 and received by the receiving unit 232.

[0048] If the service subject to search, reservation, and payment processing is a transportation service, the service usage information includes the type of transportation currently used by person PS[i], the travel section of the transportation currently used by person PS[i], and the date and time of person PS[i]'s travel using the transportation currently used.

[0049] Specifically, consider, for example, a train TR that departs from point K1a at time T1a and then arrives at point K1b at time T1b, as shown in Figure 6. The period from time T1a to time T1b is called period PP1. The service that utilizes (travels on) the train TR that travels from point K1a to point K1b during period PP1 is called service SVC1. In case CS1, person PS X The user reserves service SVC1 and receives service SVC1 during period PP1 according to the reservation details. Furthermore, each of the multiple user PSs is a user PS. X This is possible, but simply put, one person PS is a person PS X It can be considered equivalent to this. In Case CS1, the person PS involved in Case CS1 is X The reservation details are for the person PS X It is included in the user input information. Therefore, in case CS1, the service identification unit F21 is person PS X It is determined that service SVC1 will be used during period PP1, and service usage information indicating the details of that determination is generated.

[0050] Each terminal device 100 may transmit terminal location information acquired by the GPS processing unit 150 to the system management device 200 in real time. The terminal location information from each terminal device 100 is received by the receiving unit 232. In this case, the behavior information of person PS[i] may include the terminal location information of terminal device 100[i]. The service utilization identification unit F21 can improve the accuracy of determining which service person PS[i] is currently using by referring to the terminal location information of terminal device 100[i].

[0051] Still, the person PS[i] may input the current action taken by the person PS[i] into the terminal device 100[i] by themselves. In this case, the input content may be included in the user input information of the person PS[i] (therefore, the action information of the person PS[i]). That is, for example, when the person PS[i] is taking the train TR and receiving the service SVC1 during the period PP1 in FIG. 6, the person PS[i] may input that they are on the train TR into the terminal device 100[i] by themselves. Or, the person PS[i] may input that they plan to take the train TR and receive the service SVC1 during the period PP1 into the terminal device 100[i] before the period PP1. Then, based on the input content to the terminal device 100[i], the service usage specifying unit F21 can determine that the person PS[i] uses the service SVC1 during the period PP1 and generate service usage information indicating the determination result.

[0052] The analysis and evaluation unit F22 generates evaluation information related to the service based on the biological information of one or more persons PS and the service usage information of one or more persons PS. The biological information of the person PS[i] is received by the receiving unit 232. The evaluation information generated by the analysis and evaluation unit F22 is particularly referred to as comprehensive evaluation information.

[0053] Assuming the case CS1 in FIG. 6, the function of the analysis and evaluation unit F22 will be specifically described. In the case CS1, since the person PS X is specified (judged or estimated) to use the service SVC1, the analysis and evaluation unit F22 analyzes the physical condition, mood, etc. of the person PS X during the period PP1 based on the biological information of the person PS X during the period PP1, and generates comprehensive evaluation information for the service SVC1. In the case CS1, the comprehensive evaluation information for the service SVC1 is information representing the evaluation of the person PS X for the service SVC1.

[0054] The comprehensive evaluation information for the service SVC1 is the person PS who is receiving the service SVC1 XIt includes information representing the level of comfort. As information representing the level of comfort, a comfort index, which quantifies the level of comfort, is included in the overall evaluation information. The comfort index in the overall evaluation information for Service SVC1 is Person PS X Person PS when receiving service SVC1 X This is a numerical representation of the degree of comfort. Here, the comfort level is represented by a numerical value (e.g., an integer) between 1 and 5 in the comfort index. A higher comfort level corresponds to a larger value in the comfort index. The analysis and evaluation unit F22 performed the analysis on the person's PS during period PP1. X Person PS when receiving service SVC1 based on biometric information X By estimating the level of comfort, the person PS for service SVC1 X We derive comfort indicators. For example, the person's PS during period PP1. X Based on biometric information, person PS X If it is estimated that the person harbors unpleasant feelings during period PP1, the analysis and evaluation department F22 will perform the person PS for service SVC1. X Set the comfort index to "1" or "2". Alternatively, for example, the person's PS during period PP1. X Based on biometric information, person PS X If it is estimated that the person is experiencing pleasant emotions during period PP1, the analysis and evaluation department F22 will evaluate the person's PS for service SVC1. X Set the comfort index to "4" or "5".

[0055] One method involves a person manually uploading evaluation comments and other information about a service to a website after using that service. In contrast, this embodiment generates evaluation information about the service based on biometric information, without requiring manual input of evaluation comments or other information.

[0056] The terminal feedback unit F23 generates feedback evaluation information based on the overall evaluation information generated by the analysis and evaluation unit F22, and transmits the generated feedback evaluation information to one or more terminal devices 100 using the transmission unit 231. Upon receiving the feedback evaluation information, the terminal device 100 sends a notification to the user of the terminal device 100 (i.e., the person PS) corresponding to the feedback evaluation information. Specific examples of this will be given in a later embodiment.

[0057] The overall evaluation information itself may be feedback evaluation information, or a part of the overall evaluation information may be feedback evaluation information. The feedback evaluation information may also be the information representing the level of comfort (i.e., the comfort index) mentioned above.

[0058] Figure 7 shows an example of comprehensive evaluation information. The comprehensive evaluation information includes the comfort index mentioned above. The comprehensive evaluation information may further include all or part of the relaxation index, motion sickness index, near-miss index, and evaluation text information. Using Service SVC1 as an example, the relaxation index, motion sickness index, near-miss index, and evaluation text information for Service SVC1 will be explained.

[0059] The relaxation index in the overall evaluation information for service SVC1 is the person PS X Person PS when receiving service SVC1 X This quantifies the degree of relaxation. Here, the relaxation index is represented by a number between 1 and 5 (for example, an integer). The higher the degree of relaxation, the larger the relaxation index. The analysis and evaluation unit F22 analyzes the person's PS during period PP1. X Based on biometric information, the person's PS when receiving service SVC1. X By estimating the degree of relaxation of the person, the person's PS for service SVC1 is calculated. X Derive the relaxation index.

[0060] The motion sickness index in the overall evaluation information for Service SVC1 is based on the person's PS. XPerson PS when receiving service SVC1 X This is a numerical representation of the degree of motion sickness experienced. Here, the motion sickness index is expressed as a numerical value (e.g., an integer) between 1 and 5, indicating the severity of motion sickness. A lower value on the motion sickness index indicates a more severe degree of motion sickness. (Person PS during period PP1) X Based on biometric information, the person PS for service SVC1 X The motion sickness index is derived.

[0061] The near-miss indicator in the overall evaluation information for service SVC1 is the person PS. X Person PS when receiving service SVC1 X This quantifies the number or severity of near misses experienced by a person. Here, the near miss index represents the number or severity of near misses using a numerical value (e.g., an integer) between 1 and 5. A lower value on the near miss index indicates a higher number of near misses or a more severe near miss. Person PS during period PP1 X Based on biometric information, the person PS for service SVC1 X The near-miss indicator is derived.

[0062] The evaluation text information in the overall evaluation information for service SVC1 is from person PS. X Person PS when receiving service SVC1 X This is wording that expresses the feelings held by the character. Character PS during period PP1 X Based on the biometric information, evaluation text information for service SVC1 is derived. For example, multiple predefined phrases are prepared in advance, and for each predefined phrase, a corresponding pattern of biometric information change is pre-set as a registered change pattern. Then, the person's PS during period PP1 is... X The similarity between the former and the latter is evaluated by comparing the change patterns of biometric information with multiple registered change patterns for multiple standard phrases. Among the multiple registered change patterns, the first registered change pattern corresponds to the person's PS during period PP1. XIf it is determined that the first registered change pattern is most similar to the change pattern of the biometric information, the first standard phrase corresponding to the first registered change pattern is set in the evaluation phrase information. Similarly, among the multiple registered change patterns, if the second registered change pattern is the person PS in period PP1 X If it is determined that the pattern of change in the biological information is most similar to the second registered change pattern, a second standard phrase corresponding to the second registered change pattern will be set in the evaluation text information. The same applies to the third registered change pattern, etc.

[0063] As a concrete example, the pattern of changes in a person's biometric information in a comfortable environment is pre-set as the first registered change pattern, and the sentence "I was able to spend my time very comfortably" is set as the first standard phrase. The pattern of changes in a person's biometric information in a poor environment is pre-set as the second registered change pattern, and the sentence "It's hard to say it was comfortable" is set as the second standard phrase. In this case, the person's PS during period PP1 X If the pattern of change in biometric information is similar to the first and second registered change patterns, then the first and second standard phrases will be, respectively, the person's PS X The wording that represents the feelings held by the individual will be set as evaluation wording information.

[0064] Comprehensive evaluation information is useful for improving various services. For example, it can be used to provide the comprehensive evaluation information itself, or a report containing the comprehensive evaluation information, to businesses that operate or develop various services, either free of charge or for a fee.

[0065] The following describes several embodiments related to the SYS system. In this embodiment, the matters described above apply to each of the following embodiments unless otherwise specified and without contradiction. In the event of any conflict between the matters described above and those described in each embodiment, the description in the respective embodiment may take precedence. Furthermore, unless there is a contradiction, the matters described in any of the embodiments shown below may be applied to any other embodiment (i.e., it is possible to combine any two or more embodiments from the multiple embodiments).

[0066] <<First Example>> The first embodiment will now be described. In the method according to the first embodiment, an evaluation information regarding a service received by a certain person is notified to that person. The person who receives the notification is referred to as the target person. The target person is one of persons PS[1] to PS[n]. Figure 8 shows the operation flowchart of the system SYS according to the first embodiment. The operation of the system SYS according to the first embodiment will be explained in accordance with the operation flowchart in Figure 8.

[0067] First, in step S11, the service identification unit F21 identifies the services used by the target person as target services based on the target person's behavioral information and generates service information indicating the identification result. In the following step S22, the target person's biometric information during the period in which the target person receives the target services (hereinafter referred to as the target period) is received by the receiving unit 232 and sent to the analysis and evaluation unit F22. In the following step S13, the analysis and evaluation unit F22 generates comprehensive evaluation information of the target person regarding the target services based on the target person's biometric information during the target period.

[0068] Subsequently, in step S14, the terminal feedback unit F23 transmits feedback evaluation information based on the overall evaluation information generated in step S13 to the target person's terminal device 100 using the transmission unit 231. In the following step S15, the feedback evaluation information is received by the receiving unit 132 at the target person's terminal device 100.

[0069] Subsequently, in step S16, the terminal control unit 110 in the target person's terminal device 100 performs the first evaluation notification process. The first evaluation notification process may be performed according to program PG1a. In the first evaluation notification process, the received feedback evaluation information is notified to the target person as service evaluation information for the target service. The notification may be made by display using the display screen 171, by audio output using the speaker 174, or a combination of both. The service evaluation information notified to the target person in the first evaluation notification process is information generated by the management control unit 210 based on the target person's biometric information during the target period.

[0070] If we apply the operation in Figure 8 to Case CS1 in Figure 6, the target person is Person PS. X This corresponds to the service SVC1, and the target period corresponds to period PP1. The target person (PS) during the target period (PP1) X Based on the biometric information of the subject, comprehensive evaluation information is generated (step S13) and service evaluation information is notified to the subject (step S16).

[0071] Figure 9 shows an example of the first evaluation notification process. In Figure 9, it is assumed that the target person is person PS[1], and therefore the first evaluation notification process is performed on the terminal device 100[1]. In the first evaluation notification process in Figure 9, a comfort level notification image 610 is displayed on the display screen 171 of the terminal device 100[1]. The overall evaluation information generated in step S13 includes a comfort index, and feedback evaluation information including the comfort index is received by the terminal device 100[1] (step S15). The comfort level notification image 610 represents the value of the comfort index in the received feedback evaluation information. That is, the comfort level of the target person while they are receiving the target service is objectively judged based on their biometric information, and the result is notified to the target person.

[0072] When the target service is service SVC1, the terminal control unit 110 in the terminal device 100[1] displays an image 612 showing the content of service SVC1 along with a comfort level notification image 610. In other words, service evaluation information (610) is notified to the target person in association with the target service (SVC1). Therefore, the target person can recognize which service the notified service evaluation information corresponds to. Although an example of notifying a comfort index is given here, other information in the overall evaluation information (relaxation index, motion sickness index, near-miss index, or evaluation wording information) may also be included in the feedback evaluation information and notified to the target person as service evaluation information.

[0073] Note that the display example in Figure 9 assumes that the transmission and reception of feedback evaluation information and notification to the target person take place during the target period. However, the transmission and reception of feedback evaluation information and notification to the target person may take place at any time after the target period. For example, after the target period, the person PS[1], as the target person, may input a predetermined operation to the terminal device 100[1] to transmit and receive feedback evaluation information and notify the target person.

[0074] By receiving notifications through the first evaluation notification process, the subject can objectively understand whether they are comfortably using the service, what impression they have of the service, and so on. In the case of health management application programs, there are practical examples of measuring, estimating, or collecting daily exercise, sleep, or stress levels to help manage one's health status. The method according to the first embodiment produces a similar effect. For example, if the subject can commute using either the first or second mode of transportation, they can compare the feedback evaluation information from commuting using the first mode of transportation with the feedback evaluation information from commuting using the second mode of transportation, and use this to help them choose which mode of transportation to use in the future.

[0075] <<Second Example>> A second embodiment will be described. In the method according to the second embodiment, evaluation information of a service received by a certain reference person is notified to the target person. The reference person and the target person are different people and are one of persons PS[1] to PS[n]. Figure 10 shows the operation flowchart of the system SYS according to the second embodiment. The operation of the system SYS according to the second embodiment will be explained in accordance with the operation flowchart in Figure 10.

[0076] First, in step S21, the service identification unit F21 identifies the services used by the reference person as target services based on the reference person's behavioral information and generates service information indicating the identification result. In the following step S22, the reference person's biometric information during the period in which the reference person receives the target services (hereinafter referred to as the reference period) is received by the receiving unit 232 and sent to the analysis and evaluation unit F22. In the following step S23, the analysis and evaluation unit F22 generates comprehensive evaluation information of the reference person for the target services based on the reference person's biometric information during the reference period.

[0077] Subsequently, in step S24, the terminal feedback unit F23 transmits feedback evaluation information based on the overall evaluation information generated in step S23 to the target person's terminal device 100 using the transmission unit 231. In the following step S25, the feedback evaluation information is received by the receiving unit 132 at the target person's terminal device 100.

[0078] Subsequently, in step S26, the terminal control unit 110 in the target person's terminal device 100 performs a second evaluation notification process. The second evaluation notification process may be performed according to program PG1a. In the second evaluation notification process, the received feedback evaluation information is notified to the target person as service evaluation information for the target service. The notification may be made by display using the display screen 171, by audio output using the speaker 174, or a combination of both. The service evaluation information notified to the target person in the second evaluation notification process is information generated by the management control unit 210 based on the reference person's biometric information during the reference period.

[0079] If we apply the operation in Figure 10 to Case CS1 in Figure 6, the reference person is Person PS. X This corresponds to service SVC1, and the reference period corresponds to period PP1. The reference person (PS) during the reference period (PP1) XBased on the biometric information of the person, comprehensive evaluation information is generated (step S23) and service evaluation information is notified to the person (step S26). In the second embodiment, the person is person PS X This refers to a different person, for example, a person who is considering using train TR after period PP1. More specifically, for example, when the target person searches for a service equivalent to service SVC1 using their terminal device 100 on a date later than the date to which period PP1 belongs, they receive a notification through the second evaluation notification process. Here, an equivalent service refers to a service that allows travel by public transport from point K1a to point K1b between times T1a and T1b on a date later than the date to which period PP1 belongs.

[0080] Figure 11 shows an example of the second evaluation notification process. In Figure 11, it is assumed that the target person is person PS[1], and therefore the second evaluation notification process is performed on the terminal device 100[1]. In the second evaluation notification process in Figure 11, a comfort level notification image 620 is displayed on the display screen 171 of the terminal device 100[1]. The overall evaluation information generated in step S23 includes a comfort index, and feedback evaluation information including the comfort index is received by the terminal device 100[1] (step S25). The comfort level notification image 620 represents the value of the comfort index in the received feedback evaluation information. That is, the comfort level of the reference person while they are receiving the target service is objectively judged based on their biometric information, and the result is notified to the reference person.

[0081] When the target service is service SVC1, the terminal control unit 110 in the terminal device 100[1] displays an image 622 showing the content of service SVC1 along with a comfort level notification image 620. In other words, service evaluation information (620) is notified to the target person in association with the target service (SVC1). Therefore, the target person can recognize which service the notified service evaluation information corresponds to. If the train TR is composed of multiple connected cars, the target person may also be notified which car the service evaluation information (620) corresponds to. Here, an example is given in which a comfort index is notified, but other information in the overall evaluation information (relaxation index, motion sickness index, near-miss index, or evaluation wording information) may also be included in the feedback evaluation information and other information may be notified to the target person as service evaluation information.

[0082] By receiving a notification through the second evaluation notification process, the individual can learn about other people's evaluations of the service in question, which can help them make decisions about receiving similar services in the future.

[0083] Furthermore, the first and second embodiments may be combined. In this case, the subject may receive both the notification from the first evaluation notification process (see Figure 9) and the notification from the second evaluation notification process (see Figure 11) simultaneously.

[0084] <<Third Example>> A third embodiment will now be described. In the second embodiment, there may be multiple reference persons. For example, in case CS1 of Figure 6, if persons PS

[0100] to PS

[0199] receive service SVC1 during period PP1, the operation of the second embodiment will be as follows.

[0085] In other words, each of the individuals PS

[0100] to PS

[0199] functions as a reference person. In step S21, the service usage identification unit F21 identifies the service SVC1 used by each reference person as the target service based on the behavioral information of each reference person, and generates service usage information indicating the identification result. In the following step S22, the biometric information of each reference person during the reference period (PP1) in which each reference person receives the target service is received by the receiving unit 232 and sent to the analysis and evaluation unit F22. In the following step S23, the analysis and evaluation unit F22 generates comprehensive evaluation information of the reference person for the target service based on the biometric information of each reference person during the reference period.

[0086] The overall evaluation information for each referenced person generated here includes overall evaluation information for each referenced person, as well as statistical information on the overall evaluation information of all referenced people (hereinafter referred to as statistical evaluation information). Statistical evaluation information is generated by applying statistical processing to the overall evaluation information for each referenced person. Similar to the overall evaluation information for each referenced person, the statistical evaluation information may include comfort index, relaxation index, motion sickness index, and near-miss index. However, the comfort index in the statistical evaluation information has statistical values ​​(e.g., mean, median, maximum, or minimum) for the comfort index of each referenced person. The same applies to the relaxation index, motion sickness index, and near-miss index in the statistical evaluation information.

[0087] Subsequently, in step S24, the terminal feedback unit F23 transmits feedback evaluation information based on the overall evaluation information generated in step S23 to the target person's terminal device 100 using the transmission unit 231. In the following step S25, the feedback evaluation information is received by the receiving unit 132 at the target person's terminal device 100. The feedback evaluation information transmitted and received here may be information based on the statistical evaluation information mentioned above, and therefore, in the second evaluation notification process in step S26, the information in the statistical evaluation information may be notified to the target person as service evaluation information. For example, the statistical values ​​of the comfort index for each reference person may be associated with the target service and notified to the target person. An example of this notification is the same as that shown in Figure 11. However, the comfort level notification image 620 in Figure 11 is an image showing the statistical values ​​of the comfort index for each reference person.

[0088] <<Fourth Example>> A fourth embodiment will now be described. In the second or third embodiment, the management control unit 210 can treat all persons PS who received the target service as reference persons, or it can treat only some of the persons PS who received the target service as reference persons. The latter method will be explained below. The matching unit F24 in Figure 5 is involved in the implementation of the latter method. First, the function of the matching unit F24 will be explained. To make the explanation more concrete, in the fourth embodiment, the period PP1 in case CS1 is considered to be the reference period, and the target service is considered to be the service SVC1 in period PP1.

[0089] The control unit 210 continuously receives biometric information of each person PS during the preparation period prior to period PP1. The matching unit F24 (see Figure 5) associates two or more person PSs from person PS[1] to PS[n] with each other based on the biometric information of person PS[1] to PS[n] during the preparation period. The preparation period is the time required for this association, and can be, for example, several days to several weeks long.

[0090] The matching unit F24 performs a matching process that compares the biometric information of individuals PS[1] to PS[n] during the preparation period between different individuals PS, thereby associating two or more individuals PS[1] to PS[n] with each other. For example, the matching unit F24 compares the change pattern of biometric information of individual PS[i] during the preparation period with the change pattern of biometric information of individual PS[j] during the preparation period and derives a similarity between the two (i and j are different natural numbers less than or equal to n). Only when the derived similarity is equal to or greater than a predetermined criterion similarity is individual PS[i] and individual PS[j] associated with each other. The result of the association by the matching unit F24 is transmitted to the analysis and evaluation unit F22 and the terminal feedback unit F23.

[0091] Multiple individuals (PS) matched by the matching unit F24 are presumed to be a group of individuals with similar tendencies regarding changes in their biometric information, and are expected to experience similar levels of comfort and satisfaction when receiving the same service.

[0092] Therefore, the terminal feedback unit F23 according to the fourth embodiment transmits feedback evaluation information, taking into consideration the result of the matching by the matching unit F24. Consider the case where the target person is person PS[1], and of people PS[2] to PS[n], only people PS

[80] to PS

[0139] are associated with person PS[1] by the matching unit F24. In this case, assume that of people PS[1] to PS[n], only people PS

[0100] to PS

[0199] received service SVC1 during period PP1. Then, the analysis and evaluation unit F22 and the terminal feedback unit F23 according to the fourth embodiment set only the people who received service SVC1 during period PP1 and are associated with person PS[1] by the matching unit F24 as reference people for the target person PS[1]. Hence, here, only people PS

[0100] to PS

[0139] are set as reference people. However, the total number of reference people set may be "1". Except for the fact that the reference person is set using the matching unit F24, the other operations may be the same as those shown in the second or third embodiment, and the target person receives notification through the second evaluation notification process as shown in Figure 11.

[0093] By receiving a notification through the second evaluation notification process, the target individual can learn about the reference individual's evaluation of the service in question, which can help them make decisions about receiving similar services in the future. In this case, it is expected that the target individual and the reference individual constitute a group of people who would feel similar levels of comfort, etc., when receiving the same service. Therefore, the usefulness of notifications through the second evaluation notification process is expected to increase.

[0094] In the specific example described here, the control unit 210 sets the combination of the target person (PS[1]) and the reference person for each of the persons PS[1] to PS[n] during a period different from the reference period (preparation period) (in other words, it selects the person who should be associated with the target person (PS[1]) from among persons PS[2] to PS[n] as the reference person).

[0095] <<Example 5>> A fifth embodiment will now be described. Although it will include some overlap with the above, the functions, operations, and effects of the terminal device 100 and the system management device 200 will be explained here.

[0096] The system management device 200 is wirelessly connected to multiple terminal devices 100. The system management device 200 includes an evaluation processing unit that generates evaluation information for the target service based on the biometric information of each user during the period in which each user of each terminal device 100 is receiving the target service (see, for example, the third embodiment). The management control unit 210 itself or the calculation processing unit 210a is an example of the evaluation processing unit. The overall evaluation information is an example of the evaluation information generated by the evaluation processing unit.

[0097] One method involves an individual manually uploading their evaluation (evaluation comments, etc.) of a service to a website after using that service. In contrast, this embodiment generates service evaluation information based on biometric data without requiring manual input of evaluations. This reduces the effort required for manual input, and because biometric data is collected without manual input, an increase in the sample size of the information that forms the basis of the evaluation can be expected. Furthermore, while evaluations (evaluation comments, etc.) entered manually tend to contain arbitrary information, biometric data is thought to more accurately reflect the impressions a person has. Therefore, it becomes possible to make more accurate evaluations regarding the quality of the service.

[0098] The terminal device 100 for the target person comprises an interface unit 170 capable of outputting information to the target person, and a terminal processing unit. The terminal control unit 110 itself or the arithmetic processing unit 110a is an example of the terminal processing unit. In the terminal device 100 for the target person, the terminal processing unit can use the interface unit 170 to notify the target person of service evaluation information based on the biometric information of one or more persons during the period in which one or more persons are receiving the target service, in association with the target service. In the first embodiment, the one or more persons are the target person (see Figures 8 and 9), and in the second to fourth embodiments, the one or more persons are one or more reference persons (see Figures 10 and 11).

[0099] One method involves an individual manually uploading their evaluation (evaluation comments, etc.) of a service to a website after using that service. In contrast, this embodiment enables the notification of service evaluation information based on biometric data without requiring manual input of evaluations, thus reducing the effort involved in manual input. Furthermore, while manually entered evaluations (evaluation comments, etc.) tend to contain arbitrary information, biometric data is considered to more accurately reflect the impressions a person has. Therefore, it becomes possible to notify more accurate evaluation information regarding the quality of the service, etc.

[0100] <<Sixth Example>> A sixth embodiment will now be described. In this sixth embodiment, the function of the service proposal unit F25 (see Figure 5) provided in the management control unit 210 will be explained.

[0101] The biometric information of each person PS is received in real time by the receiving unit 232. That is, the management control unit 210 can obtain the current biometric information of each person PS. Based on the current biometric information of each person PS, the service suggestion unit F25 can set for each person PS which services are recommended for use or which services should be prohibited from use from among the services available to that person PS. The setting results by the service suggestion unit F25 are transmitted from the transmission unit 231 to the terminal device 100 of the corresponding person PS, and the terminal device 100 of the corresponding person PS is notified. Focusing on the target person as the person receiving the notification, the method according to the sixth embodiment will be described in detail.

[0102] The service suggestion unit F25 sets which services are recommended for use or which should be prohibited from use from among the services available to the target person, based on the target person's current biometric information. The setting result is transmitted from the transmission unit 231 to the target person's terminal device 100, and the target person is notified on the terminal device 100. Hereinafter, services that are recommended for use will be referred to as recommended services, and services that should be prohibited from use will be referred to as unrecommended services.

[0103] Refer to Figure 12 for a specific example. Here, we assume that the target person is person PS[1]. Person PS[1] operates their terminal device 100[1] to instruct the terminal device 100[1] to search for a route (transfer search, etc.) to travel from station STN1 to station STN2 using public transportation. Station STN1 is the departure station, and station STN2 is the arrival station, which is the destination. At this time, person PS[1] inputs search specification information 660 into the terminal device 100[1], specifying stations STN1 and STN2 as the departure and arrival stations. Upon receiving this input, the terminal device 100[1] executes the search process described above. The search specification information 660 is transmitted from the terminal device 100[1] to the system management device 200.

[0104] Here, we assume there are two routes, RT1 and RT2, that start from station STN1 and end at station STN2. Route RT1 is the route from station STN1 to station STN2 by train TR1, and route RT2 is the route from station STN1 to station STN2 by train TR2. Here, we assume that the system management device 200 is given information that train TR2 is less crowded and more comfortable than train TR1. However, route RT2 requires a higher fare than route RT1. The transportation service that travels from station STN1 to station STN2 along route RT1 by train TR1 is called service SVC. A This is referred to as the SVC service, which provides transportation from station STN1 to station STN2 via train TR2 along route RT2. B It is called that.

[0105] After routes RT1 and RT2 are retrieved based on search specification information 660, the service proposal unit F25 determines the service SVC based on the current biometric information of person PS[1]. A or SVC B Sets the service as either a recommended service or a non-recommended service. The current biometric information of person PS[1] is, for example, biometric information for a certain period of time that includes the time when the search specification information 660 was entered into the terminal device 100[1]. The service proposal unit F25 estimates the current health condition of person PS[1] based on the current biometric information of person PS[1], and based on the estimation result, the service SVC A or SVC B Set it as a recommended service or a non-recommended service. Here, we consider two cases based on the current biometric information of person PS[1]: the first case in which person PS[1]'s current physical condition is judged to be relatively good, and the second case in which person PS[1]'s current physical condition is judged to be relatively bad.

[0106] For example, in the first case, Service SVC A Set this as the recommended service. Service proposal department F25, in the first case, Service SVC A Set the service SVC as the recommended service. BYou may set it as a deprecated service. Here, in the first case, service SVC A It is set as the recommended service and the service SVC B Assume that the service is set to deprecated. These settings are sent from the system management device 200 to the terminal device 100[1], and the search results for routes RT1 and RT2 are also sent to the terminal device 100[1]. The search results for routes RT1 and RT2 may be sent from the system management device 200, or from other search devices not shown.

[0107] Figure 13 shows an example of the display of search results on terminal device 100[1] in the first case. In terminal device 100[1], terminal control unit 110 displays an image on display screen 171 that reflects the search results of routes RT1 and RT2 and the setting results of service proposal unit F25. In the first case, the contents of routes RT1 and RT2 are displayed on display screen 171 of terminal device 100[1], but a recommended use marker 663a is displayed corresponding to route RT1, and a not recommended use marker 663b is displayed corresponding to route RT2. The recommended use marker 663a is for the service SVC by route RT1. A Marker 663b indicates a recommended service, while marker 663b indicates a service SVC provided by route RT2. B This indicates that it is a deprecated service. In this case, the terminal control unit 110 of the terminal device 100[1] may display recommendation information on the display screen 171 such as, "Your current physical condition seems good, so we recommend using the advantageous route RT1."

[0108] In the terminal device 100[1] relating to the first case, the terminal control unit 110 controls the service SVC by route RT1 set as the recommended service. A Only the results may be displayed on the display screen 171 as route search results. In the terminal device 100[1] relating to the first case, the service SVC by route RT2 BWhen displaying this on the display screen 171, the terminal control unit 110 may also display discouraging information on the display screen 171 such as, "Your current physical condition seems good, so you may want to refrain from using the expensive Route RT2."

[0109] Conversely, in the second case, Service SVC B Set this as the recommended service. Service proposal department F25, in the second case, Service SVC B Set the service SVC as the recommended service. A You may set it as a deprecated service. Here, in the second case, service SVC B It is set as the recommended service and the service SVC A Assume that it is set as a deprecated service. These settings are sent from the system management device 200 to the terminal device 100[1], and the search results for routes RT1 and RT2 are also sent to the terminal device 100[1].

[0110] Figure 14 shows an example of the display of search results on the terminal device 100[1] in the second case. In the terminal device 100[1], the terminal control unit 110 displays an image on the display screen 171 that reflects the search results of routes RT1 and RT2 and the setting results of the service proposal unit F25. In the second case, the contents of routes RT1 and RT2 are displayed on the display screen 171 of the terminal device 100[1], but a recommended usage marker 664a is displayed corresponding to route RT2, and a not recommended usage marker 664b is displayed corresponding to route RT1. The recommended usage marker 664a is the service SVC by route RT2. B Marker 664b indicates a recommended service, while marker 664b indicates a service SVC provided by route RT1. A This indicates that it is a deprecated service. In this case, the terminal control unit 110 of the terminal device 100[1] may display recommendation information on the display screen 171 such as, "It appears that you are not feeling well at the moment, so we recommend that you use Route RT2, which will allow you to spend your time more comfortably."

[0111] In the terminal device 100[1] relating to the second case, the terminal control unit 110 controls the service SVC by route RT2 set as the recommended service. B Only the results may be displayed on the display screen 171 as route search results. In the terminal device 100[1] relating to the second case, the service SVC by route RT1 A When displaying this on the display screen 171, the terminal control unit 110 may also display a discouragement notice on the display screen 171 such as, "Currently, you do not appear to be in good health, so we do not recommend using the often congested route RT1."

[0112] In this manner, the terminal control unit 110 of the target person's terminal device 100 uses the interface unit 170 to notify the target person of services that are recommended to be used (recommended services) or services that should be avoided (not recommended services) based on the target person's current biometric information. This makes it possible to propose appropriate services that take into account the target person's physical condition, etc. In the examples of Figures 13 and 14, the above notification is displayed, but it may also be a notification via voice output.

[0113] Furthermore, in the example shown in Figure 12, the service SVC A and Service SVC B These are mapped to separate routes, but the service SVC A and Service SVC B These may be transportation services on the same route. That is, for example, when a train going from station STN1 to station STN2 has both a regular car with a relatively low fare and a special car with a relatively high fare, the transportation services using the regular car and the special car are, respectively, service SVC. A SVC B That's fine too.

[0114] For the sake of simplicity, I have given an example that considers only two routes, but even when three or more routes are found, the same recommended or discouraged service settings can be applied as described above.

[0115] Furthermore, while transportation services are used as an example here, the same may apply when facility services are the subject of the search. For example, when person PS[1], as the target person, uses terminal device 100[1] to search for facilities within a certain area, the service SVC may be used for sports facilities within that area. A Service SVC provides services that utilize bathing facilities within the area. B With this understanding, it is permissible to issue the same notification as described above. However, here we assume that sports facilities are associated with relatively good physical condition, and bathing facilities are associated with relatively poor physical condition.

[0116] In the second case, the terminal device 100[1] may also notify the person PS[1], who is the target person, that he should refrain from using public transportation or facilities. For example, the terminal device 100[1] in the second case may, in response to the input of the search specification information 660, notify the person PS[1] of a message such as, "You appear to be not feeling well. It would be best to refrain from using public transportation or facilities."

[0117] When setting recommended or non-recommended services for a target person, the method according to the fourth embodiment may be applied, and the comfort index of the person associated with the target person may be referenced. This will be explained further. Consider the case where the target person is person PS[1], and person PS[2] is associated with person PS[1] by the matching unit F24 according to the fourth embodiment. Also, in the past, person PS[2] was service SVC A and SVC B It uses the person PS[2] service SVC A When the person PS[2] receives the service SVC, the comfort index of the person PS[2] and the service SVC of the person PS[2] B Assume that the comfort index of person PS[2] when receiving has already been derived. In this case, the search process executed by person PS[1] inputting search specification information 660 (Figure 12) to terminal device 100[1] results in the service SVC A and SVC BAssume that it is derived as a search result. Then, the service proposal unit F25 uses the comfort index of the person PS[2] when the person PS[2] received the service SVC in the past and the comfort index of the person PS[2] when the person PS[2] received the service SVC A in the past. And the service proposal unit F25 refers to the comfort index of the person PS[2] when the person PS[2] received the service SVC B in the past. Then, based on the referred comfort index, the service proposal unit F25 can set the services SVC A and SVC B for the person PS[1] as recommended services or non-recommended services respectively.

[0118] For example, if the comfort index of the person PS[2] when the person PS[2] received the service SVC A in the past has a value of "4" or "5", then set the service SVC A for the person PS[1] as a recommended service, and if it has a value of "1" or "2", then set the service SVC A for the person PS[1] as a non-recommended service. The same applies to the service SVC B . When the person PS[2] is associated with the person PS[1] by the matching unit F24 according to the fourth embodiment, it is expected that both of them will feel the same comfort level when receiving the same service. As described above, the recommended service or non-recommended service can be notified to the target person (here PS[1]).

[0119] <<Embodiment 7>> Embodiment 7 will be described. In the system SYS, a mechanism can be introduced in which a reward is given to a person PS who has provided his or her own biological information. As a result, an incentive for providing biological information works, and an increase in the amount of biological information collected is expected. Consequently, the evaluation of the service can be made more accurate. It also leads to an improvement in the satisfaction of each person PS.

[0120] The nature and method of rewards are arbitrary. For example, the reward may be a price discount applied when purchasing a specific product, a coupon usable at a restaurant, or virtual currency usable within the SYS system. The reward may be granted under the control of the management control unit 210. For example, the management control unit 210 grants the reward to person PS[i] in association with the account information corresponding to person PS[i].

[0121] The management control unit 210 derives the degree of contribution to service evaluation cooperation for each person PS and determines the reward to be given according to the degree of contribution. In this case, the higher the degree of contribution, the higher the reward given. The management control unit 210 may also transmit the degree of contribution for each person PS to the terminal device 100, and the degree of contribution may be displayed on the display screen 171 of each terminal device 100.

[0122] For example, the longer the period during which biometric information is provided along with behavioral information, the higher the contribution. Also, for example, the more biometric information a person PS[i] provides while actually using the service they reserved, such as performing search, reservation, and payment processing on terminal device 100[i], the higher the contribution. Also, for example, the more types of biometric information provided, the higher the contribution. For example, comparing the case where only body temperature and blood pressure are provided with the case where biometric information including pulse rate, body temperature, blood pressure, sweating amount, and blood oxygen concentration is provided, the latter case will have a higher contribution.

[0123] <<Example 8>> The eighth embodiment will now be described. If the transportation service used by person PS is a taxi, the service may be evaluated for each taxi company or each driver. In this embodiment, "driver" refers to a taxi driver.

[0124] For example, in the reservation process at terminal device 100, it is assumed that the user can reserve a taxi while specifying the driver. When the reservation process is executed at terminal device 100[i] with the driver specified, action information (see Figure 5) indicating the details of the reservation is transmitted from terminal device 100[i] to system management device 200. At this time, the service usage identification unit F21 recognizes that person PS[i] is moving while riding in a taxi with the specified driver according to the reservation details, and includes the recognition result in the service usage information.

[0125] Subsequently, at the reserved date and time, person PS[i] actually boards a taxi driven by the designated driver and travels. Biometric information of person PS[i] while traveling in the taxi is sent from terminal device 100[i] to analysis and evaluation unit F22. Based on the service usage information and the biometric information of person PS[i] while traveling in the taxi, analysis and evaluation unit F22 generates comprehensive evaluation information for the driver designated by person PS[i].

[0126] By performing this process for multiple drivers, comprehensive evaluation information for each driver can be obtained. This comprehensive evaluation information for each driver can be provided to the taxi operating company and used to help manage the taxi business.

[0127] Furthermore, the overall evaluation information for each driver can be used to help with subsequent taxi searches. For example, consider a situation where overall evaluation information is derived for each of the 1st to 5th drivers of taxis operating within the same area, and the average value of the comfort index in the overall evaluation information for driver i is "TD[i]". In this situation, suppose person PS[1] wishes to use a taxi service within the above area and has terminal device 100[1] perform a search process according to that wish. Then, terminal device 100[1] displays the search results on display screen 171. In this case, for example, as shown in Figure 15, terminal control unit 110 may display the 1st to 5th drivers on display screen 171 sorted in descending order of the average value of the corresponding comfort index. The sorting criteria do not have to be the comfort index. For example, sorting could be done based on the motion sickness index (sorting based on the motion sickness index is beneficial for person PS who is concerned about motion sickness).

[0128] <<Ninth Example>> A ninth embodiment will be described. The analysis and evaluation unit F22 may be equipped with a machine learning model obtained through machine learning. In this case, the analysis and evaluation unit F22 may use the machine learning model to generate comprehensive evaluation information based on biological information.

[0129] Specifically, as shown in Figure 16(a), a deep neural network (hereinafter referred to as DNN) 410 is provided in a machine learning device 400, which is composed of one or more arbitrary processing units. The machine learning device 400 performs supervised machine learning on the DNN 410 based on a training dataset. In order to perform this supervised machine learning, a data collection step is first required to collect a training dataset. Figure 17 shows a flowchart of the operation to obtain a trained model. The data collection step is performed in step S91.

[0130] The training dataset includes sample data. The sample data includes biometric information of a sample person placed in a given environment, and the level of comfort the sample person felt in that environment. The level of comfort in the sample data is a subjective level of comfort determined by the sample person, and has an integer value between 1 and 5. The higher the comfort level the sample person feels, the higher the value of the comfort level should be set. In the data collection process, a large amount of such sample data is acquired and accumulated and included in the training dataset. It is desirable to include sample data for a large number of sample people in the training dataset. Each sample person may or may not match any of the person PS[1] to PS[n].

[0131] The DNN410 receives biometric information of sample individuals as input and outputs a comfort level (see Figure 16(b)). After the data collection process, in the machine learning process of step S92, the machine learning device 400 uses the comfort levels in each sample data as training data (ground truth) to perform supervised machine learning on the DNN410. After supervised machine learning, the DNN410 becomes an inference model that infers a person's comfort level based on their biometric information. If the obtained inference model is installed in the analysis and evaluation unit F22, the analysis and evaluation unit F22 can derive the comfort level (comfort index) of each person PS based on the biometric information of each person PS.

[0132] In the Analysis and Evaluation Department F22, a method for generating a model to derive comfort levels (comfort index) was explained, but the same method may be used for relaxation index, motion sickness index, and near-miss index. Evaluation wording information may also be created using artificial intelligence obtained through machine learning.

[0133] Furthermore, the system management device 200 may have a machine learning device 400 built into it, or the system management device 200 itself may be the machine learning device 400. The system management device 200 and the machine learning device 400 may be different devices from each other.

[0134] <<Tenth Example>> A tenth embodiment will now be described. The terminal control unit 110 may implement all or part of the functions of the management control unit 210.

[0135] For example, the functions of the analysis and evaluation unit F22 may be implemented in the terminal control unit 110. That is, in the terminal device 100[1], the terminal control unit 110 may derive or generate comfort indicators, relaxation indicators, motion sickness indicators, near-miss indicators, and evaluation wording information for person PS[1] based on the biometric information of person PS[1], without relying on the functions of the system management device 200. If person PS[1] is using service SVC1 related to case CS1 in Figure 6, the terminal control unit 110 of the terminal device 100[1] may derive comfort indicators, etc. for person PS[1] related to service SVC1 based on the biometric information of person PS[1] during period PP1. Then, as shown in the first embodiment (see Figure 9), in the terminal device 100[1], the terminal control unit 110 may associate the comfort indicators, etc. it has derived with service SVC1 as service evaluation indicators (610) and notify person PS[1]. The same applies to terminal devices 100[2]~100[n] and person PS[2]~PS[n].

[0136] <<Example 11>> The 11th embodiment will now be described.

[0137] The system management device 200 may receive evaluation information manually entered by a person PS who has used any service. Manually entered evaluation information is information entered by the person PS into the terminal device 100 using the interface unit 170, and represents the person PS's evaluation of the service used. Manually entered evaluation information is transmitted from the terminal device 100 to the system management device 200. By using evaluation information based on biometric information and manually entered evaluation information in combination, the system management device 200 can create higher quality evaluation information.
