[0013] (First embodiment) A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram showing an example of the configuration of an information processing system SYS according to the first embodiment of the present invention. The information processing system SYS includes an information processing device 100, a local government server device 200, and a terminal device 300. The information processing device 100, the local government server device 200, and the terminal device 300 are communicably connected.

[0014] The information processing system SYS is an information processing system that stores map data, registers area information, sets a starting point and a destination point, connects the starting point and the destination point with a straight line, sets a rectangular area including the straight line, and sets a route from the starting point to the destination point that avoids areas based on the area information within the rectangular area.

[0015] The information processing device 100 is a server device. The information processing device 100 manages map data. The information processing device 100 acquires and stores area information from a local government server device 200. The area information is, for example, information indicating an area where there is a risk regarding travel. The risk is at least one of a risk of traffic congestion, a risk due to weather, a risk due to disasters, a risk based on past accidents or disaster records, and a risk due to public safety.

[0016] The information processing device 100 acquires a departure point and a destination point from the terminal device 300. The departure point may be any location or may be the current location where the terminal device 300 is located. The information processing device 100 connects the departure point and the destination point with a straight line and sets a rectangular area including the straight line. Specifically, the information processing device 100 sets a rectangular area with the straight line as its diagonal line. The information processing device 100 sets a route from the departure point to the destination point that avoids areas within the rectangular area based on the area information.

[0017] In this way, the information processing device 100 can set a route that avoids areas where risks exist (also referred to as risk areas). Furthermore, the information processing device 100 can set a route without informing the user (terminal device 300) that there is a risk area, which can prevent the user from having a negative impression of places where risk areas exist. Therefore, the information processing device 100 can easily provide the shortest route to the destination that avoids risky places.

[0018] The information processing device 100 may be a server device that functions on the cloud, or may function by being executed on the terminal device 300 as an application having the functions of the information processing device 100. The information processing device 100 may be realized by one server device or by multiple server devices.

[0019] The local government server device 200 is a server device managed by a local government. The local government server device 200 has a function of communicating with the information processing device 100. The local government server device 200 manages area information such as risks due to weather, risks due to disasters, risks based on records of past accidents and disasters, and risks due to public safety.

[0020] The risks in area information may be acquired in real time or predicted based on past records, and information on areas where risks exist may be registered and managed by reflecting this information.

[0021] The terminal device 300 is a terminal device used by a user, such as a smartphone, a tablet terminal, or an in-vehicle display. The terminal device 300 has a function of communicating with the information processing device 100. Note that the number of terminal devices 300 may be one or more.

[0022] The information processing device 100 will be described in more detail.

[0023] FIG. 2 is an explanatory diagram showing an example of a route search in the information processing device 100 according to this embodiment. FIG. 3 is an explanatory diagram showing an example of a route search in the information processing device 100 according to this embodiment. In the examples shown in Figures 2 and 3, areas A1 and A2 on the map are areas indicated by area information, for example. Spot G1 is a destination point set by the user. Spots SP1, SP2, and SP3 are spots recommended for passing through, for example. As shown in Figure 3, the information processing device 100 sets a route to the destination that passes through spots SP1, SP2, and SP3, which are recommended spots to be added, thereby providing the shortest route to the destination that avoids areas based on the area information and does not pass through areas A1 and A2 shown in Figure 2.

[0024] It is possible to arbitrarily set whether or not areas in the area information where risks exist are to be displayed on the map.

[0025] Next, the functional configuration of the information processing device 100 will be described.

[0026] FIG. 4 is a block diagram showing an example of the functional configuration of the information processing device 100 according to this embodiment. The information processing device 100 includes a communication unit 110, a storage unit 120, an input unit 130, an output unit 140, and a control unit 150. The communication unit 110 has a function of communicating with the local government server device 200 and the terminal device 300 .

[0027] The storage unit 120 is configured by a storage medium, such as a hard disk drive (HDD), flash memory, electrically erasable programmable read-only memory (EEPROM), random access read / write memory (RAM), read-only memory (ROM), or any combination of these storage media. The storage unit 120 may be, for example, a nonvolatile memory.

[0028] The storage unit 120 stores various types of data. The storage unit 120 stores, for example, interest information 121, map data 122, spot information 123, and area information 124.

[0029] The interest information 121 is information indicating the user's interests. The interest information 121 is information indicating whether the user is interested in, for example, food and drink, history, flora and fauna, art, disaster prevention and crime prevention, daily life and procedures, child rearing, education, health, welfare and medical care, tourism and events, sports and playgrounds, public relations, garbage, etc. Disaster prevention and crime prevention may be further subdivided to indicate whether the user is interested in specific items such as crime prevention, disaster prevention, and fire and emergency.

[0030] The map data 122 is map data of open data.

[0031] The spot information 123 is information indicating spots that are recommended to be passed through. The spot may indicate an arbitrary point, or may indicate a predetermined range including the arbitrary point, or an arbitrary range. Each spot is set with a category and subcategory to which the spot corresponds. The category and subcategory correspond to interest information.

[0032] The area information 124 is information indicating a risk area.

[0033] The input unit 130 is an input device such as a mouse or keyboard connected to the information processing device 100. The input unit 130 accepts an operation input input from outside. The input unit 130 outputs an operation signal to the control unit 150 in accordance with the operation input.

[0034] The output unit 140 is an output device such as a display device, etc. The output unit 140 outputs information output from the control unit 150 to its own output device or to another device.

[0035] The control unit 150 has a function of controlling each unit of the information processing device 100 . The control unit 150 includes a setting unit 151 , a point linking unit 152 , an area setting unit 153 , a route setting unit 154 , an area information registration unit 155 , a spot information registration unit 156 , and an interest information registration unit 157 .

[0036] The setting unit 151 acquires information on the departure point and destination from the terminal device 300 and sets them as the departure point and destination point. The setting unit 151 includes a departure point setting unit 1511 and a destination point setting unit 1512 . The departure point setting unit 1511 sets the departure point information acquired from the terminal device 300 as the departure point. The destination point setting unit 1512 sets the destination information acquired from the terminal device 300 as the destination point.

[0037] The point connection unit 152 connects the departure point and the destination point with a straight line.

[0038] The area setting unit 153 sets a rectangular area that includes the straight lines connected by the point connection unit 152. Specifically, the area setting unit 153 sets a rectangular area with the straight lines as diagonals. The area setting unit 153 determines whether the set rectangular area is equal to or smaller than a threshold. Specifically, the area setting unit 153 determines whether the width or height of the set rectangular area is equal to or smaller than a threshold. If the width or height of the rectangular area is equal to or smaller than the threshold, the area setting unit 153 enlarges the rectangular area according to a predetermined ratio, and sets a rectangular area including the straight lines connected by the point connection unit 152.

[0039] If the spot is not included in the set rectangular area, the area setting unit 153 To Alternatively, if the risk area cannot be avoided within the rectangular area, the area setting unit 153 may expand the rectangular area until the risk area can be avoided.

[0040] The route setting unit 154 sets a route from a departure point to a destination point within the rectangular area set by the area setting unit 153, avoiding areas based on the area information. Specifically, the route setting unit 154 reads the area information 124, the spot information 123, and the interest information 121 from the storage unit 120. The route setting unit 154 extracts spots included in the rectangular area as spot candidates from among the spots included in the spot information. The route setting unit 154 excludes spots within risk areas within the rectangular area from among the spots included in the rectangular area. Alternatively, the route setting unit 154 extracts spots outside the risk areas within the rectangular area from among the spots included in the rectangular area as spot candidates. The route setting unit 154 excludes spots in a category that does not interest the user from among the spots within the rectangular area by referring to the interest information. Alternatively, the route setting unit 154 extracts spots in a category that interests the user from among the spots within the rectangular area by referring to the interest information. The route setting unit 154 sets spot candidates selected from the spot candidates within the rectangular area based on the interest information and area information as spots, and sets a route from the departure point to the destination point that passes through the spots as an avoidance route. Here, the interest information and area information can be selected by the local government server device 200 or the user.

[0041] The number of spots in a risk area or an avoidance route may be filtered so as to be adjustable by the user. Furthermore, the user may tag candidate spots (spots) or risk areas, and reconfigure the avoidance route based on the tags. The route setting unit 154 may determine whether a path is a road or a sidewalk, and then set a route that passes through that path (for example, a sidewalk for walking or cycling, or a road for a car).

[0042] The area information registration unit 155 has a function of registering area information. The area information registration unit 155 stores the area information acquired from the local government server device 200 in the storage unit 120. The area information registration unit 155 also generates area information from various types of information such as traffic congestion information and weather information using AI or machine learning. The area information registration unit 155 stores the generated area information in the storage unit 120.

[0043] The spot information registration unit 156 acquires spot information from another device (for example, the local government server device 200) or input from the input unit 130, and stores the information in the storage unit 120.

[0044] The interest information registration unit 157 acquires the user's interest information from the terminal device 300 and stores it in the storage unit 120.

[0045] The various processes performed by the control unit 150 of the information processing device 100 will be described in more detail.

[0046] FIG. 5 is an explanatory diagram showing an example of information processing in the information processing device 100 according to this embodiment. The departure point setting unit 1511 sets a departure point S1 based on the current location of the terminal device 300. The destination point setting unit 1512 sets a destination point G2 based on the destination acquired from the terminal device 300. The point connector 152 connects the departure point S1 and the destination point G2 with a straight line. The area setting unit 153 sets a rectangular area AR1 whose diagonal line is a straight line connecting the starting point S1 and the destination point G2. The route setting unit 154 refers to the spot information and excludes the spot candidate SP1, the spot candidate SP2, the spot candidate SP3, and the spot candidate SP4 that are outside the rectangular area AR1. The route setting unit 154 refers to the interest information and excludes spot candidates SPK5 in categories that do not correspond to the user's interest information. The route setting unit 154 refers to the area information and excludes the spot candidate SP6 included in the risk area A3.

[0047] FIG. 6 is an explanatory diagram showing an example of information processing in the information processing device 100 according to this embodiment. As shown in Figure 5, the spot candidates SP7 and SP8 that ultimately remain within the rectangular area AR1 are designated as spots SP4 and SP5, and the route setting unit 154 sets a route from the starting point S1 to the destination point G2 via spots SP4 and SP5 as shown in Figure 6. The information processing device 100 may provide route guidance from the departure point to the destination point along the set route.

[0048] FIG. 7 is an explanatory diagram showing an example of information processing in the information processing device 100 according to this embodiment. FIG. 8 is an explanatory diagram showing an example of information processing in the information processing device 100 according to this embodiment. As shown in Figure 7, if the rectangular area AR2 with the diagonal line connecting the starting point S2 and the destination point G1 is straight, that is, if the rectangular area is less than the threshold value, the area setting unit 153 expands the rectangular area according to a predetermined ratio, as shown in Figure 8, and sets a rectangular area AR3 including the straight line connected by the point connection unit 152.

[0049] Here, rectangular areas AR1, AR2, and / or AR3 are not normally displayed on the map, but are set by control unit 150. However, rectangular areas AR1, AR2, and / or AR3 may be displayed on the map.

[0053] In step S103, the information processing device 100 connects the departure point and the destination point with a straight line and sets a rectangular area with the straight line as its diagonal. The information processing device 100 determines whether the set rectangular area is equal to or smaller than a threshold. If the rectangular area is equal to or smaller than the threshold (YES in step S103), the information processing device 100 executes the process of step S104. On the other hand, if the rectangular area is not equal to or smaller than the threshold (NO in step S103), the information processing device 100 executes the process of step S105.

[0054] In step S104, the information processing device 100 resets the rectangular area. Next, the information processing device 100 executes the process of step S103.

[0055] In step S105, the information processing device 100 acquires spot information from the storage unit 120. Next, the information processing device 100 executes the process of step S106.

[0056] In step S106, information processing device 100 acquires interest information from storage unit 120. Next, information processing device 100 executes the process of step S107.

[0057] In step S107, the information processing device 100 acquires area information from the storage unit 120. Next, the information processing device 100 executes the process of step S108.

[0058] In step S108, the information processing device 100 extracts target spots by excluding non-target spot candidates based on the rectangular region, interest information, and area information. Then, the process of step S109 is executed.

[0059] In step S109, the information processing device 100 sets a route from the departure point to the destination point via the spots, and then the information processing device 100 ends the information processing in FIG.
