Mode for Carrying Out the Invention

[0022] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

[0023] <1. Tourist Route Proposal System> FIG. 1 is a diagram showing a schematic configuration of a tourist route proposal system 100 according to an embodiment of the present invention. As shown in FIG. 1, the tourist route proposal system 100 includes a tourist route proposal device 1 and a route generation device 2.

[0024] The tourism route proposal device 1 is a device that proposes a tourism route to a user. The tourism route proposal device 1 is preferably a device that can be directly used by the user. The tourism route proposal device 1 is connected to the communication network 3. The communication network 3 is configured to include at least any one of, for example, an Internet line, a telephone line, a LAN (Local Area Network), and WiFi (registered trademark). In the present embodiment, the tourism route proposal device 1 is a terminal device. The tourism route proposal device 1 is, for example, a mobile terminal. The tourism route proposal device 1 may be, for example, a personal computer, a smartphone, or a tablet, etc. Details of the tourism route proposal device 1 will be described later.

[0025] The route generation device 2 is provided to be communicable with the tourism route proposal device 1 and generates a proposed tourism route. The proposed tourism route is a tourism route proposed to the user. The route generation device 2 is connected to the communication network 3. The tourism route proposal device 1 and the route generation device 2 are connected to each other via the communication network 3. In the present embodiment, the route generation device 2 generates a proposed tourism route in response to a request from the tourism route proposal device 1 and outputs the generated proposed tourism route toward the tourism route proposal device 1. The route generation device 2 is a server device. The route generation device 2 may be composed of one server device, but may also be composed of a plurality of server devices. The route generation device 2 may be, for example, a cloud server. The route generation device 2 may also be composed of a plurality of cloud servers.

[0026] Note that the tourism route proposal device 1 may be configured to have a function of generating a proposed tourism route. In this case, the route generation device 2 may not be provided.

[0027] The route generation device 2 automatically selects tourist spots within a specified area and generates a proposed tourist route (proposed tourist route) including means of transportation between the tourist spots. Tourist spots include, for example, scenic spots, historical sites, temples, shrines, amusement parks, museums, art galleries, restaurants, etc. Means of transportation include, for example, walking, cycling, railways, buses, taxis, etc. The route generation device 2 may generate a tourist route using, for example, a trained model that has performed machine learning. The route generation device 2 generates a tourist route using a database that stores tourist information related to the specified area. The tourist information includes map information, location information of tourist spots, cost information required at tourist spots, fare information for public transportation, fare information for taxis, etc.

[0028] The route generation device 2 generates a proposed tourist route based on tourist parameters indicating tourist conditions set by the user. The route generation device 2 generates a tourist route having tourist parameters close to the tourist parameters set by the user as the proposed tourist route. Tourist parameters are, for example, parameters indicating the user's desires (desired conditions) during tourism. It is preferable that the number of tourist parameters is plural. In this embodiment, the number of tourist parameters is plural.

[0029] In this embodiment, as an example, the tourist parameters include parameters related to the user's resources (physical strength, money, time) and parameters related to satisfaction that may be in a trade-off relationship with the user's resources. Specifically, the tourist parameters include a physical strength parameter related to the remaining amount of physical strength consumed by tourism, a money parameter related to the remaining amount of money consumed by tourism, a time parameter related to the remaining amount of time consumed by tourism, and a satisfaction parameter related to the satisfaction obtained by tourism. By using these tourist parameters to generate a tourist route, it is possible to propose a tourist route that meets the user's needs.

[0030] The physical strength parameter is a parameter related to the remaining amount of physical strength after physical strength is consumed by sightseeing. The physical strength parameter is, for example, a parameter that affects means of transportation during sightseeing, etc., and is a parameter quantified using statistical data, etc. For example, when sightseeing on foot, a large amount of physical strength is consumed by sightseeing, and the value of the physical strength parameter indicating the remaining amount of physical strength becomes small. Depending on the value of the set physical strength parameter, whether to use vehicles such as rental cars, trains, buses, taxis, etc. as the means of transportation changes. Note that depending on what is selected as the means of transportation, it also affects the number and location of sightseeing spots that can be visited.

[0031] The money parameter is a parameter related to the remaining amount of money after money is consumed by sightseeing. The money parameter is, for example, a parameter that affects sightseeing spots where a person sightseeing stops by, means of transportation during sightseeing, etc. For example, depending on the set money parameter, whether to make a sightseeing spot where a fee is incurred the stop-by location changes. Also, for example, depending on the set money parameter, whether to use a vehicle such as a rental car where a fee is incurred changes, or the type of vehicle to be used changes.

[0032] The time parameter is a parameter related to the remaining amount of time after time is consumed by sightseeing from the time secured or planned in advance. The time parameter is, for example, a parameter that affects means of transportation during sightseeing, staying time at sightseeing spots, the number of sightseeing spots, etc. For example, depending on the length of time available for sightseeing, that is, depending on the set time parameter, whether to take an efficient route to visit many sightseeing spots during sightseeing or to take a leisurely sightseeing route, etc. changes.

[0033] The satisfaction parameter is a parameter determined considering a trade-off relationship with the physical strength parameter, the money parameter, and the time parameter, and is, for example, a parameter quantified using statistical data, etc. For example, the value of the parameter may be determined so that the satisfaction is high for a sightseeing route with good movement efficiency such as visiting many sightseeing spots in a short time.

[0034] Note that, for example, satisfaction levels and the like may vary depending on the nationality of the tourists. Therefore, for example, the data used to generate the tourist route and the method of using the data may be changed according to the nationality of the tourists.

[0035] Also, for generating a tourist route based on tourist parameters, known techniques may be used. For example, for generating a tourist route using the physical strength parameter, money parameter, time parameter, and satisfaction parameter described above, the techniques disclosed in "Proceedings of the Multimedia, Distributed Cooperation and Mobile Symposium 2019; A Method for Presenting Multiple Tourist Routes for Decision Support Considering User Resource Consumption, Authors: Yota Hirano, Hirohiko Suwa, Keiichi Yasumoto" and the like may be used.

[0036] As will be described later, the tourist route proposal device 1 of the present embodiment is configured to be able to propose a tourist route that a person traveling feels is easy to use. Therefore, a user who uses the tourist route proposal system of the present embodiment can comfortably receive the tourist route proposal service.

[0037] <2. Tourist Route Proposal Device> (2-1. Configuration of Tourist Route Proposal Device) FIG. 2 is a block diagram showing the configuration of the tourist route proposal device 1 according to an embodiment of the present invention. Note that in FIG. 2, only the components necessary for explaining the features of the embodiment are shown, and the description of general components is omitted. As shown in FIG. 2, the tourist route proposal device 1 includes a control unit 11, a storage unit 12, and a communication unit 13.

[0038] The control unit 11 is a controller that comprehensively controls the entire tourism route proposal device 1. The control unit 11 is configured to include, for example, an integrated circuit for arithmetic operations, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The integrated circuit for arithmetic operations may be, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or an APU (Accelerated Processing Unit).

[0039] The storage unit 12 may be, for example, a flash memory, a hard disk drive (HDD), an optical disk drive, or a memory card. The storage unit 12 stores various programs and various data. In the present embodiment, the programs stored in the storage unit 12 include a program 121 that causes the control unit 11 (computer) to execute a tourism route proposal method for proposing a tourism route to the user. The program 121 is specifically application software (hereinafter referred to as an app).

[0040] The communication unit 13 is connected to the communication line network 3 by wire or wirelessly, and communicates with the route generation device 2 via the communication line network 3.

[0041] The setting value acquisition unit 111, the priority acquisition unit 112, the tourism route request unit 113, the tourism route acquisition unit 114, the display processing unit 115, and the correction processing unit 116 shown in FIG. 2 are functions of the control unit 11 realized by the integrated circuit for arithmetic operations of the control unit 11 executing arithmetic processing according to a computer program. In other words, the control unit 11 includes a setting value acquisition unit 111, a priority acquisition unit 112, a tourism route request unit 113, a tourism route acquisition unit 114, a display processing unit 115, and a correction processing unit 116.

[0042] Further, at least one of the setting value acquisition unit 111, priority acquisition unit 112, tourist route request unit 113, tourist route acquisition unit 114, display processing unit 115, and correction processing unit 116 included in the control unit 11 may be configured by hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). Also, the setting value acquisition unit 111, priority acquisition unit 112, tourist route request unit 113, tourist route acquisition unit 114, display processing unit 115, and correction processing unit 116 are conceptual components. The functions executed by one component may be distributed among multiple components, or the functions of multiple components may be integrated into one component.

[0043] The setting value acquisition unit 111 acquires the user's setting values of the tourism parameters indicating the tourism conditions. The number of the user's setting values is the same as the number of the tourism parameters. When there are a plurality of tourism parameters indicating the tourism conditions, there are also a plurality of the user's setting values. In the present embodiment, the tourism parameters include a physical strength parameter, a money parameter, a time parameter, and a satisfaction parameter. The user inputs these tourism parameters using an operation unit (not shown). The operation unit may be, for example, a touch panel, a keyboard, a keypad, a mouse, a button, or the like. Note that the operation unit may be a part of the tourist route proposal device 1 or may be separate from the tourist route proposal device 1. The setting value acquisition unit 111 acquires the setting values of the tourism parameters input by the user via the operation unit.

[0044] By adopting a configuration in which the tourism parameters include a physical strength parameter, a money parameter, a time parameter, and a satisfaction parameter, the user can decide at his or her own will which of the resources he or she has to consume for tourism and request a proposal of a tourist route. That is, according to this configuration, a tourist route can be proposed that meets the user's needs.

[0045] The priority acquisition unit 112 acquires a priority indicating which of the plurality of tourism parameters is to be prioritized. Note that when the number of tourism parameters is singular, the priority acquisition unit is unnecessary. Also, even when there are a plurality of tourism parameters, the configuration may be such that the priority acquisition unit 112 is not provided. The priority is input by the user. It is preferable that the user can select whether to input the priority or not. The same operation unit as the above-described operation unit may be used for the user to input the priority. The priority may be configured to indicate only the tourism parameter that the user values most among the plurality of tourism parameters. Also, the priority may be the priority order given for all of the plurality of tourism parameters. The acquisition of the priority may be before or after the acquisition of the tourism parameters.

[0046] The tourism route request unit 113 transmits the set values of the acquired tourism parameters to the route generation device 2 using the communication unit 13, and requests the route generation device 2 to generate a proposed tourism route based on the set values. Note that the tourism route request unit 113 may transmit data other than the set values of the tourism parameters to the route generation device 2 as necessary. The data may include the above-described priority.

[0047] The tourism route acquisition unit 114 acquires the proposed tourism route generated by the route generation device 2 based on the set values of the tourism parameters via the communication network 3. The number of acquired proposed tourism routes is not particularly limited and may be singular or plural. Also, depending on the set values of the tourism parameters, it may not be possible to generate a proposed tourism route corresponding to the set values. Considering this point, it is preferable that the tourism route acquisition unit 114 is configured to be able to acquire that the proposed tourism route could not be generated.

[0048] Note that, as described above, the tourism route proposal device 1 may be configured to be able to generate a proposed tourism route. In this case, the tourism route proposal device 1 may be configured to include a tourism route generation unit as a functional unit and not include the tourism route request unit 113 and the tourism route acquisition unit 114.

[0049] The display processing unit 115 performs processing related to the display on the screen 4 of the display unit (see FIG. 4 and the like described later). The display unit is a display configured using, for example, a liquid crystal panel, an organic EL panel, or the like. The display unit may be a component provided in the tourism route proposal device 1. Further, the display unit may be provided separately from the tourism route proposal device 1 and connected to the tourism route proposal device 1 by wire or wirelessly.

[0050] In the present embodiment, the display processing unit 115 performs processing to display the proposed tourism route generated based on the set value of the tourism parameter on the screen 4. Specifically, the display processing unit 115 superimposes and displays the proposed tourism route on the map. Further, the display processing unit 115 performs processing to display a parameter information section 42 (see FIG. 4 and the like described later) indicating information related to the tourism parameter on the screen 4. Specifically, the parameter information section 42 is displayed within the screen 4 on which the proposed tourism route is displayed. That is, the user can also confirm the information related to the tourism parameter from the screen 4 on which the proposed tourism route is displayed. Details of the parameter information section 42 will be described later.

[0051] The correction processing unit 116 accepts changes to some of the proposed contents included in the proposed tourism route and performs correction processing on the proposed tourism route. The correction processing is processing to make some corrections to the proposed contents, and is different from processing to re-propose the entire proposed tourism route in response to a change in the set value of the tourism parameter. Details of the correction processing will be described later.

[0052] (2-2. Tourism Route Proposal Method) Next, a tourism route proposal method for proposing a tourism route to a user using a device will be described. FIG. 3 is a flowchart showing the flow of the tourism route proposal method executed by the tourism route proposal device 1 according to an embodiment of the present invention. The tourism route proposal method shown in FIG. 3 is started, for example, when the user executes the app 121 for tourism route proposal. Note that when starting the tourism route proposal method, the user may be configured to input the preconditions for tourism. The preconditions may include, for example, the area of tourism, the departure and arrival locations of tourism, the maximum consumption time allowed during tourism, the maximum consumption amount allowed during tourism, and the like. Further, the preconditions may include a priority indicating which parameter among a plurality of tourism parameters is to be prioritized. Further, the preconditions may include the tourism spots that the user wants to visit.

[0053] In step S1, a parameter setting screen, which is a screen 4 for the user to set tourism parameters, is displayed. When the display of the parameter setting screen is completed, the process proceeds to the next step S2. Here, the parameter setting screen will be described with reference to FIG. 4. FIG. 4 is a diagram schematically showing an example of a state in which the parameter setting screen is displayed. In the example shown in FIG. 4, the tourism route proposal device 1 is a mobile terminal such as a smartphone or a tablet, and is provided with the ability to input by a touch panel method.

[0054] On the screen 4, a map information section 41 and a parameter information section 42 are displayed. The map information section 41 includes a map MP. For example, the map information section 41 displays a map of a certain range including the current location obtained by the GPS (Global Positioning System) of the tourism route proposal device 1. However, at this stage, as long as the tourism parameters can be set, the map information section 41 may not be provided.

[0055] The parameter information section 42 includes a parameter value display section 421 and a parameter setting section 422. In this embodiment, there are four tourism parameters. Therefore, there are four parameter value display sections 421 and four parameter setting sections 422, respectively. Specifically, the parameter value display section 421 includes a physical strength parameter value display section 421a, a time parameter value display section 421b, a money parameter value display section 421c, and a satisfaction parameter value display section 421d. Also, the parameter setting section 422 includes a physical strength parameter setting section 422a, a time parameter setting section 422b, a money parameter setting section 422c, and a satisfaction parameter setting section 422d.

[0056] The parameter value display section 421 indicates the value of the tourism parameter. Specifically, the physical strength parameter value display section 421a indicates the value of the physical strength parameter. The time parameter value display section 421b indicates the value of the time parameter. The money parameter value display section 421c indicates the value of the money parameter. The satisfaction parameter value display section 421d indicates the value of the satisfaction parameter. In this embodiment, the physical strength parameter, the time parameter, the money parameter, and the satisfaction parameter are represented as percentages. The closer the value of the physical strength parameter is to 100%, the less physical strength is consumed by tourism and the more physical strength remains. The closer the value of the time parameter is to 100%, the less time is consumed by tourism and the more time remains. The closer the value of the money parameter is to 100%, the less money is consumed by tourism and the more money remains. The closer the value of the satisfaction parameter is to 100%, the higher the satisfaction obtained from tourism.

[0057] For example, when the value of the physical strength parameter is 0%, it indicates that the walking distance during tourism is the maximum walking distance assumed for the user. The maximum walking distance is estimated based on, for example, the user's age, the user's walking record, etc. The user's walking record can be obtained using, for example, the function of a pedometer provided in a smartphone.

[0058] For example, when the value of the time parameter is 0%, it indicates that the time used for sightseeing uses up all of the available time for sightseeing, the time based on the desired itinerary, etc. The available time for sightseeing is, for example, pre-input by the user. The available time for sightseeing may be configured to be calculated from the departure time of a train such as the Shinkansen for which the user has a scheduled ride.

[0059] For example, when the value of the money parameter is 0%, it indicates that all of the money available for sightseeing is used up. The money available for sightseeing is, for example, pre-input by the user.

[0060] For example, the satisfaction parameter is an estimated value of the user's satisfaction with the proposed sightseeing route. The satisfaction parameter may be configured to be input by the user as in this embodiment. In this case, the set satisfaction may be understood to indicate the minimum level of satisfaction (minimum satisfaction) desired by the user. Also, the satisfaction parameter may be configured to be automatically estimated according to the set values of other parameters. In the case of this configuration, the satisfaction parameter may be determined based on the evaluation after generating the proposed sightseeing route based on the values of parameters other than the satisfaction parameter such as the physical strength parameter.

[0061] The parameter setting unit 422 enables setting of the values of the sightseeing parameters. Specifically, the physical strength parameter setting unit 422a enables setting of the value of the physical strength parameter. The time parameter setting unit 422b enables setting of the value of the time parameter. The money parameter setting unit 422c enables setting of the value of the money parameter. The satisfaction parameter setting unit 422d enables setting of the value of the satisfaction parameter. In this embodiment, the parameter setting unit 422 is configured using a slider. That is, the parameter setting unit 422 can set the value of the sightseeing parameter by varying the length in the left-right direction of the slide bar 4221 displayed on the touch panel.

[0062] In addition, in this embodiment, the parameter setting unit 422 is configured using a slider, but this is merely an example. The parameter setting unit 422 may have other configurations, such as a configuration for inputting the values of the tourism parameters. When the parameter setting unit 422 is configured using a slider, it is convenient because the parameters can be easily set by an operation using a finger. Also, for example, when the parameter setting unit is configured to input the values of the tourism parameters, the parameter value display unit 421 may not be provided.

[0063] Also, in the above description, the physical strength parameter, time parameter, and money parameter are configured to be indicated by the remaining amount, but they may be configured to be indicated by the consumption amount (usage amount). Further, it may be configured such that the display based on the remaining amount and the display based on the consumption amount can be switched.

[0064] Also, in the above description, the values of each parameter are configured to be "displayed as a percentage" (configured to be indicated by a ratio), but as shown in FIG. 4A, for at least some of the parameters, they may be configured to be indicated by actual numbers. In the example shown in FIG. 4A, for the physical strength parameter, time parameter, and money parameter, the parameter value display unit 421 is indicated by actual numbers (remaining amount numbers). For the physical strength parameter, as an example, the remaining walking distance based on the maximum walking distance assumed for the user is shown. For the time parameter, as an example, the remaining time based on the time available for the user is shown. For the money parameter, the remaining money based on the money available for the user is shown. In FIG. 4A, an example where the currency is the Japanese yen is shown, but it is preferable that the currency display can be switched to the display of the currency desired by the user.

[0065] Returning to FIG. 3, the description will be given. In step S2, the setting value acquisition unit 111 monitors whether the setting value of the tourism parameter has been acquired. When the user sets the tourism parameter using the parameter setting unit 422, the setting value acquisition unit 111 acquires the setting value of the tourism parameter. That is, the tourism route proposal method of the present embodiment includes a setting value acquisition step of acquiring the user's setting value of the tourism parameter indicating the tourism condition.

[0066] In the present embodiment, by the setting value acquisition step, the setting value of the physical strength parameter, the setting value of the time parameter, the setting value of the money parameter, and the setting value of the satisfaction parameter are acquired. When it is confirmed that the setting values of all the tourism parameters have been acquired (Yes in step S2), the process proceeds to the next step S3. When it is not confirmed that the setting values of all the tourism parameters have been acquired (No in step S2), the process of step S2 is continued. For example, when the user has input all the setting values, by configuring to touch the input completion key shown on screen 4, it is possible to easily confirm whether all the setting values have been acquired.

[0067] Note that appropriate initial values may be temporarily set for the setting values of each parameter. In such a configuration, when it is determined that the initial value has not been changed, the initial value may be used as the setting value. Further, the initial value is preferably an individual parameter that is changed for each user. Regarding the determination of each parameter, instead of the configuration using the above-described determination operation, or in addition, a configuration may be adopted in which the parameter is automatically determined when a predetermined period has elapsed without any operation being performed.

[0068] Also, in the example shown in FIG. 4, the set value of the physical strength parameter is 95%, the set value of the time parameter is 90%, the set value of the money parameter is 90%, and the set value of the satisfaction parameter is 15%. These parameters have a certain correlation. Therefore, when one or more set values are input, it may be configured such that the value setting range of at least one of the remaining parameters is restricted. For example, in the example shown in FIG. 4, the user does not want to consume any of physical strength, time, and money. In such a case, since the number of tourist spots that can be visited during sightseeing is limited, the value of the satisfaction parameter tends to be small. That is, if the value of the satisfaction parameter is set large, there may be no proposed tourist route corresponding to the conditions set by the user. Therefore, in the example shown in FIG. 4, when the physical strength parameter, the time parameter, and the money parameter are set, it may be configured such that an upper limit value occurs in the setting of the satisfaction parameter. By configuring in this way, the possibility of not obtaining a proposed tourist route can be reduced.

[0069] In step S3, the tourist route request unit 113 transmits the data including the acquired tourist parameters to the route generation device 2 to request a proposal of a tourist route. When the request is completed, the process proceeds to the next step S4.

[0070] Note that in the route generation device 2, in response to the proposal request of the tourist route, a proposed tourist route is generated based on the set values of the tourist parameters set by the user. When generating the proposed tourist route, the route generation device 2 appropriately uses the above-mentioned preconditions. In the present embodiment, the route generation device 2 sets a tourist route having a value of a tourist parameter whose difference from the set value is within a predetermined value in any of the plurality of tourist parameters as the proposed tourist route.

[0071] Specifically, the route generation device 2 sets a tourism route having values of tourism parameters within a predetermined value from the set values in all of the physical strength parameter, time parameter, money parameter, and satisfaction parameter as a proposed tourism route. The predetermined value may be determined by experiments or simulations, and may be, for example, ±10% or the like. That is, in the proposed tourism route, the difference between the value of the physical strength parameter and the set value is within ±10%, the difference between the value of the time parameter and the set value is within ±10%, the difference between the value of the money parameter and the set value is within ±10%, and the difference between the value of the satisfaction parameter and the set value is within ±10%.

[0072] The route generation device 2 generates all tourism routes that meet the requirement of within ±10% for the value of each parameter as proposed tourism routes. For this purpose, the number of proposed tourism routes can be either singular or plural. In some cases, no proposed tourism route may be generated. The route generation device 2 outputs the generated proposed tourism route to the tourism route proposal device 1. When no proposed tourism route is obtained, the route generation device 2 outputs to the tourism route proposal device 1 to that effect.

[0073] In step S4, the tourism route acquisition unit 114 acquires the proposed tourism route generated by the route generation device 2. The number of proposed tourism routes acquired by the tourism route acquisition unit 114 is singular or plural. In some cases, regardless of the request of the tourism route request unit 113, no proposed tourism route may be obtained. Here, this includes both the case where a notification that no proposed tourism route has been obtained is received and the case where a proposed tourism route has been acquired. When the tourism route acquisition unit 114 acquires a proposed tourism route, the process proceeds to the next step S5.

[0074] In step S5, the display processing unit 115 performs a process of displaying the acquired proposed tourist route on screen 4. Also, the display processing unit 115 performs a process of displaying the parameter information unit 42 on screen 4. That is, the tourist route proposal method of the embodiment includes a display processing step of performing a process of displaying on screen 4 a proposed tourist route generated based on the user-set values of tourist parameters and a parameter information unit 42 indicating information related to the tourist parameters. Note that when the proposed tourist route cannot be obtained, for example, a configuration may be adopted in which this fact is displayed on screen 4.

[0075] FIG. 5 is a diagram schematically showing an example of a state in which the proposed tourist route is displayed on screen 4. Similar to the above-described parameter setting screen (see FIG. 4), on screen 4 for displaying the proposed tourist route, a map information unit 41 and a parameter information unit 42 are displayed. The map information unit 41 and the parameter information unit 42 are arranged separately above and below. In the map information unit 41, a map MP and a proposed tourist route RT superimposed on the map MP are displayed. The proposed tourist route RT includes an icon IN indicating a tourist spot or the like. The parameter information unit 42 including a parameter value display unit 421 and a parameter setting unit 422 displays the values of the tourist parameters of the proposed tourist route RT being displayed on screen 4.

[0076] Note that in the example shown in FIG. 5, the values of the respective tourist parameters of the proposed tourist route RT being displayed on screen 4 are as follows. The value of the physical strength parameter is 90%, the value of the time parameter is 91%, the value of the money parameter is 90%, and the value of the satisfaction parameter is 20%. Also, the differences from the set values (see FIG. 4) in the respective tourist parameters are as follows. The difference from the set value in the physical strength parameter is -5%, the difference from the set value in the time parameter is +1%, the difference from the set value in the money parameter is 0%, and the difference from the set value in the satisfaction parameter is +5%. For any of the tourist parameters, the difference from the set value is within ±10%.

[0077] In this embodiment, the proposed tourism route RT and the parameter information section 42 are separately displayed on the same screen 4. For this reason, the user can easily grasp the tourism parameters corresponding to the proposed tourism route RT. In other words, in this embodiment, it can be said that the tourism parameters are the parameters displayed on the screen 4 together with the proposed tourism route RT.

[0078] Also, in this embodiment, the parameter information section 42 displayed together with the proposed tourism route RT has a configuration including a parameter value display section 421 and a parameter setting section 422. For this reason, the user can grasp at a glance the values of the tourism parameters of the proposed tourism route RT, and when the proposed tourism route is not to the user's liking, the user can easily change the setting of the tourism parameters to re-propose the tourism route.

[0079] The display processing unit 115 (display processing step) displays a comparison between the value of the tourism parameter corresponding to the proposed tourism route and the set value (the user's set value). Thereby, the user can quickly grasp the difference between their own set value and the tourism parameter corresponding to the proposed tourism route. The comparison display may be configured to display both the value of the tourism parameter corresponding to the proposed tourism route and the set value. However, the comparison display may be configured to display only one of them in a form in which the relationship with the other can be understood by the user.

[0080] In this embodiment, the display processing unit 115 (display processing step) changes at least one of the display forms of the proposed tourism route RT and the parameter information section 42 according to the difference between the value of the tourism parameter corresponding to the proposed tourism route and the set value. By adopting such a configuration, the user can quickly grasp the difference between their own set value and the tourism parameter corresponding to the proposed tourism route. That is, it is possible to propose a tourism route that is easy for the person who conducts tourism to use.

[0081] In the example shown in FIG. 5, the display processing unit 115 (display processing step) changes the display form of the parameter information unit 42 according to the difference between the value of the tourism parameter corresponding to the proposed tourism route and the set value. Specifically, the change in the display form is a change in the display form of the parameter value display unit 421. When the magnitude (absolute value) of the difference between the value of the proposed tourism parameter and the set value is within a predetermined threshold (for example, 2%), the tourism parameter value is displayed "without a frame". When the value of the proposed tourism parameter is greater than the set value by more than a predetermined threshold, the tourism parameter value is displayed "with a solid line frame". When the value of the proposed tourism parameter is less than the set value by more than a predetermined threshold, the tourism parameter value is displayed "with a dashed line frame".

[0082] In the example shown in FIG. 5, since the value (90%) of the physical strength parameter of the proposed tourism route RT is 5% smaller than the set value (95%), the value of the physical strength parameter value display unit 421a is displayed surrounded by a dashed line frame. Also, since the magnitude of the difference between the value (91%) of the time parameter of the proposed tourism route RT and the set value (90%) is 1%, the value of the time parameter value display unit 421b is displayed without a frame. Also, since the magnitude of the difference between the value (90%) of the money parameter of the proposed tourism route RT and the set value (90%) is 0%, the value of the money parameter value display unit 421c is displayed without a frame. Also, since the value (20%) of the satisfaction parameter of the proposed tourism route RT is 5% larger than the set value (15%), the value of the satisfaction parameter value display unit 421d is displayed surrounded by a solid line frame.

[0083] Note that the method for changing the display form may be a method other than the presence or absence of a frame and the change in the type of frame line. The method for changing the display form may be, for example, the change in the color of a numerical value, the presence or absence of a highlight for emphasizing the numerical value, the change in the color of the highlight for emphasizing the numerical value, the presence or absence of blinking of the numerical value, combinations thereof, and the like. Above, a configuration in which there are three types of display forms changed according to the difference from the set value has been shown, but the number of types of display forms changed according to the difference from the set value may be two, or four or more. Further, above, the configuration is such that the display form of the parameter value display unit 421 is changed, but instead of or in addition to the change in the display form of the parameter value display unit 421, a configuration may be adopted in which the display form of the parameter setting unit 422 is changed.

[0084] Also, in the present embodiment, the values of the respective tourism parameters displayed in the parameter information unit 42 are the values of the respective tourism parameters corresponding to the proposed tourism route displayed in the map information unit 41. However, the values of the respective tourism parameters displayed in the parameter information unit 42 may be configured as the set values of the user. And in this case, a configuration may be adopted in which the display form of the set value displayed in the parameter information unit 42 is changed (for example, the color is changed, etc.) according to the difference between the respective tourism parameters corresponding to the proposed tourism route RT and the respective set values. In this way, the user can easily grasp what values the set values are, and can intuitively grasp the relationship between the tourism parameters of the proposed tourism route and the set values.

[0085] Also, the display form of the proposed tourism route RT may be changed according to the difference between the value of the tourism parameter corresponding to the proposed tourism route and the set value. In this case, the change in the display form may be, for example, the change in the color for displaying the route, the change in the thickness of the display of the route, the change in the type of line for displaying the route (solid line, dashed line, etc.), combinations thereof, and the like. A specific example of the configuration will be described later (see the description part regarding FIG. 7).

[0086] As described above, there may be a plurality of proposed tourist routes acquired by the tourist route acquisition unit 114. FIG. 6 is a diagram for explaining the case where there are a plurality of proposed tourist routes. FIG. 6 schematically shows an example of a state in which a proposed tourist route RT different from the proposed tourist route RT shown in FIG. 5 is displayed on the screen 4. Also in FIG. 6, similar to FIG. 5, the map information section 41 and the parameter information section 42 are displayed. In FIGS. 5 and 6, the proposed tourist route RT and the values of the tourist parameters it has are different.

[0087] As shown in FIGS. 5 and 6, in the present embodiment, the display processing unit 115 (display processing step) sets the proposed tourist route RT having a value of the tourist parameter within a predetermined value (for example, ± 10%) from the set value in any of the plurality of tourist parameters as the display target on the screen 4. Specifically, when there are a plurality of proposed tourist routes RT having values of the tourist parameter within a predetermined value from the set value in any of the plurality of tourist parameters, the plurality of proposed tourist routes can be displayed by switching the screen 4. Thereby, the user can separately check each of the plurality of proposed tourist routes RT, and can check the details of the content of each tourist route.

[0088] Note that when a plurality of proposed tourist routes are proposed, a configuration may be adopted in which the screen 4 that collectively shows the plurality of proposed tourist routes on one map is displayed so that the user can grasp at a glance the existence and the outline of the plurality of proposed tourist routes. In the present embodiment, in order to notify that there are a plurality of proposed tourist routes, a route page number display section 43 is provided on the screen 4 (see FIGS. 5 and 6) that displays one proposed tourist route. The route page number display section 43 shows the total number of pages of the proposed tourist route and the page number of the current screen 4. In the examples shown in FIGS. 5 and 6, two proposed tourist routes are proposed, and the total number of pages of the proposed tourist route is "2". FIG. 5 shows the first page out of the total number of pages "2", and FIG. 6 shows the second page out of the total number of pages "2".

[0089] In the example shown in FIG. 6, since the magnitude of the difference between the value (95%) of the physical strength parameter of the proposed tourism route RT and the set value (95%) is 0%, the value of the physical strength parameter value display unit 421a is displayed without a frame. Also, since the magnitude of the difference between the value (90%) of the time parameter of the proposed tourism route RT and the set value (90%) is 0%, the value of the time parameter value display unit 421b is also displayed without a frame. Further, since the value (80%) of the money parameter of the proposed tourism route RT is 10% smaller than the set value (90%), the value of the money parameter value display unit 421c is displayed surrounded by a broken line frame. Also, since the value (7%) of the satisfaction parameter of the proposed tourism route RT is 8% smaller than the set value (15%), the value of the satisfaction parameter value display unit 421d is displayed surrounded by a broken line frame.

[0090] In the present embodiment, when there are a plurality of proposed tourism routes RT, the proposed tourism routes RT are proposed in ascending order of the sum of the absolute values of the differences between the user's set value and the values of the parameters of the proposed tourism routes RT for each tourism parameter.

[0091] In the proposed tourism route RT shown in FIG. 5, the absolute value of the difference between the user's set value and the value of the parameter of the proposed tourism route RT is 5% for the physical strength parameter (=|95% - 90%|), 1% for the time parameter (=|90% - 91%|), 0% for the money parameter (=|90% - 90%|), and 5% for the satisfaction parameter (=|15% - 20%|). Therefore, the sum of the above absolute values of the differences is 11% (=5% + 1% + 0% + 5%).

[0092] In the proposed tourism route RT shown in FIG. 6, the absolute value of the difference between the user's set value and the value of the parameter of the proposed tourism route RT is 0% for the physical strength parameter (=|95% - 95%|), 0% for the time parameter (=|90% - 90%|), 10% for the money parameter (=|90% - 80%|), and 8% for the satisfaction parameter (=|15% - 7%|). Therefore, the sum of the above absolute values of the differences is 18% (=0% + 0% + 10% + 8%).

[0093] The sum of the absolute values of the above differences is smaller for the proposed tourist route RT shown in FIG. 5 than for the proposed tourist route RT shown in FIG. 6. For this reason, when there are the proposed tourist route RT shown in FIG. 5 and the proposed tourist route RT shown in FIG. 6 as proposed tourist routes, the proposed tourist routes are proposed in the order of the proposed tourist route RT shown in FIG. 5 and the proposed tourist route RT shown in FIG. 6. That is, the proposed tourist route RT shown in FIG. 5 is on the first page and the proposed tourist route RT shown in FIG. 6 is on the second page, and they are displayed on screen 4.

[0094] Also, based on the sum of the absolute values of the above differences, it may be configured that the display form of the proposed tourist route RT is changed. For example, the display form of the proposed tourist route RT may be changed depending on whether the sum of the absolute values of the above differences is within a predetermined threshold value (for example, 15%) or exceeds it. In the example shown in FIG. 5, the sum of the above absolute values is 11% and is within the predetermined threshold value (= 15%). In the example shown in FIG. 6, the sum of the above absolute values is 18% and exceeds the predetermined threshold value (= 15%). For this reason, in order to change the display form of the proposed tourist route RT shown in FIG. 6 from that of the proposed tourist route RT shown in FIG. 5, it may be the display form as shown in FIG. 7. In FIG. 7, the proposed tourist route RT is shown as a dashed line, which is different from the display form in FIG. 5 where the proposed tourist route RT is shown as a solid line. As described above, the method of changing the display form may be other methods, for example, it may be configured to change the color.

[0095] Returning to FIG. 3 for explanation. When the display process in step S5 is completed, the process proceeds to the next step S6. In step S6, it is confirmed whether a new set value has been acquired by the set value acquisition unit 111. If a new set value has been acquired (Yes in step S6), the process returns to step S3. That is, the re-proposal process of the proposed tourist route is performed. If a new set value has not been acquired (No in step S6), the process proceeds to the next step S7.

[0096] In step S7, it is confirmed whether there is any change process by the user for the proposed tourism route RT. This change process will be described with reference to FIGS. 8 and 9. FIGS. 8 and 9 show the same proposed tourism route RT as the proposed tourism route RT shown in FIG. 5.

[0097] As shown in FIGS. 8 and 9, in this embodiment, on the screen 4 where the proposed tourism route RT is displayed, when the icon IN indicating a tourist spot or the proposed tourism route RT is touched, the details of the proposed content are displayed. In the example shown in FIG. 8, the icon IN indicating a tourist spot is touched, and the details of the proposed content of the tourist spot are displayed. In FIG. 8, as an example, the details of the proposed content are the name of the tourist spot and the proposed staying time. Also, in the example shown in FIG. 9, the proposed tourism route RT is touched, and the details of the proposed content of the touched part are displayed. In FIG. 9, as an example, the details of the proposed content are the display of the means of transportation, indicating that the means of transportation is a bus.

[0098] In this embodiment, the detailed display of the proposed content includes a display that allows all or part of the proposed content to be changed. In FIG. 8, the staying time is displayed in a changeable manner. That is, the user can change the staying time. For example, by touching the display part of the staying time, the user can input the desired staying time. Also, in FIG. 9, the means of transportation is displayed in a changeable manner. The user can change the means of transportation by touching the selectable means of transportation. In the example shown in FIG. 9, the changeable means of transportation is walking or taxi. That is, the user can change the means of transportation from bus to walking or taxi.

[0099] Note that above, a configuration in which the change process is performed using a touch panel has been shown, but the change process may be configured to be performed using other operation means such as a keyboard. Also, the change process of the proposed content may include a process of deleting a part of the proposed tourist spots.

[0100] Returning to FIG. 3, the description will be given. When there is no change in the proposed content by the user (Yes in step S7), the process proceeds to the next step S8. When there is a change in the proposed content by the user (No in step S7), the process proceeds to step S9. In step S8, a process is performed to determine the currently displayed proposed sightseeing route RT as the sightseeing route desired by the user. For example, it may be displayed on a confirmation screen that asks the user whether it is okay to determine the currently displayed proposed sightseeing route as the desired sightseeing route by the user. If the user selects "YES", the sightseeing route may be determined. Also, if the user selects "NO", the process may return to step S1.

[0101] In step S9, according to the change in the proposed content by the user, a process is performed to request the route generation device 2 to correct the proposed sightseeing route RT. When the process of step S9 is completed, the process returns to step S4. The route generation device 2 generates a corrected proposed sightseeing route according to the change in the proposed content and outputs it to the sightseeing route proposal device 1. The route generation device 2 makes corrections according to the change in the proposed content while using the proposed sightseeing route to be corrected as a basis. The route generation device 2 generates a corrected proposed sightseeing route so that the difference between each sightseeing parameter of the corrected proposed sightseeing route and each set value is within a predetermined value (for example, ±10%). For example, when the stay time at a certain sightseeing spot is shortened and the time parameter becomes larger than the set value by more than a predetermined value, for example, addition of a sightseeing spot may be performed.

[0102] Note that when returning from step S9 to step S4, it is preferable that the corrected proposed sightseeing route is preferentially displayed on screen 4. Other processes may be the same as the above-described processes.

[0103] As described above, in the present embodiment, the tourism route proposal method includes a modification processing step of receiving a change in some proposal contents included in the proposed tourism route and performing a modification process on the proposed tourism route. With such a configuration, it is possible to propose a tourism route that is easy for tourists (users) to use.

[0104] (2-3. Modification Example) [2-3-1. First Modification Example] Above, the case where the user does not set the priority for tourism parameters has been described. FIG. 10 is a diagram schematically showing an example of a screen 4 on which a proposed tourism route is displayed when the user sets the priority. The example shown in FIG. 10 has the same conditions as those in FIG. 4 except that the user sets the priority. Also, the proposed tourism route RT shown in FIG. 10 is the same as the proposed tourism route RT shown in FIG. 6. In the example shown in FIG. 10, among the physical strength parameter, time parameter, money parameter, and satisfaction parameter, the priority of the physical strength parameter is set to be the highest. A priority display 423 indicating that the priority of the physical strength parameter is set to be the highest is displayed.

[0105] When the priority is set, the display processing unit 115 (display processing step) preferentially displays on the screen 4 in ascending order of the difference from the set value, from the proposed tourism route having the value of the parameter with the smallest difference from the user's set value for the tourism parameter with the highest set priority. By configuring in this way, it is possible to present to the user in order from the tourism routes that are highly likely to meet the user's wishes.

[0106] In the embodiment shown above, when the setting shown in FIG. 4 was made, the proposed tourist route RT shown in FIG. 5 was displayed on screen 4 before the proposed tourist route RT shown in FIG. 6. In this regard, in this modified example, since the physical strength parameter is the most prioritized setting, for the physical strength parameter, the proposed tourist route shown in FIG. 6 (the same applies to FIG. 10), in which the difference from the user's set value is smaller than that of the proposed tourist route RT shown in FIG. 5, is preferentially displayed on screen 4. As a result, as shown in FIG. 10, in FIG. 6, the proposed tourist route RT, which was on the second page in the route page number display section 43, has become the first page.

[0107] [2-3-2. Second Modified Example] As described above, the display processing unit 115 (display processing step) enables the display of a proposed tourist route having a value of a tourist parameter whose difference from the set value is within a predetermined value for any of a plurality of tourist parameters by switching the screen. In this modified example, the tourist route proposal method includes a priority acquisition step of acquiring a priority indicating which parameter among a plurality of tourist parameters is to be prioritized. The priority acquisition step may be performed, for example, before step S1 in FIG. 3 or after step S2.

[0108] In this modified example, when the priority is set, the aforementioned predetermined value is changed according to the priority. For example, assuming that the priority of the physical strength parameter is set to be the highest among the physical strength parameter, time parameter, money parameter, and satisfaction parameter. In this case, for example, the predetermined value for the physical strength parameter may be set to 5%, and the predetermined value for the other tourist parameters may be set to 10%. By adopting such a configuration, it is possible to propose a tourist route that better meets the conditions desired by the user.

[0109] Note that, as described above, the priority may be the priority order given to each tourist parameter. In this case, the predetermined value may be different for each tourist parameter.

[0110] [3.
