  The terminal device 10 is an electronic device such as a smartphone, a tablet terminal, a mobile phone, a navigation terminal, a notebook PC (Personal Computer), a desktop PC, a game device, or a wearable device that is used by a user. The user can display a map on the display device of the terminal device 10 by operating the terminal device 10 and requesting the server device 20 to display an electronic map (hereinafter simply referred to as “map”). it can. A terminal application 11 for displaying a map is installed (installed) in the terminal device 10. In addition, although the map display system 1 shown in FIG. 1 has shown the structure containing the one terminal device 10 as an example, it is not restricted to this, The map display system 1 contains the several terminal device 10. FIG. It may be.

  The server device 20 is an information processing device that transmits data (display data) for displaying a map on the terminal device 10 in response to a map display request from the terminal device 10. The server device 20 is equipped with a server program 21 for generating the display data. In the map display system 1 shown in FIG. 1, the server device 20 is configured by a single information processing device as an example, but is not limited thereto, and the server device 20 is configured by a plurality of information processing devices. May be.

<Overview>
Next, an outline of a map displayed on the display device of the terminal device 10 (that is, a map displayed based on the display data described above) will be described with reference to FIG. FIG. 2 is a diagram for explaining an outline of an example map displayed by the map display system according to the first embodiment.

  First, for example, the user designates a facility name of a destination (destination) desired by the user and displays a map on the terminal device 10. Then, in the prior art, for example, a map 1000 as shown in FIG. That is, in the map 1000 displayed on the terminal device 10, in addition to the user's current location 1100 and destination 1200, the notes 1301-1305 are map notes indicating the names of facilities on the map according to the scale of the map 1000. Is displayed. At this time, the user goes to the destination 1200 with reference to the notes 1301 to 1305 displayed on the map 1000, but when the facility shown in the notes 1301 to 1305 is not familiar, the notes 1301 to 1305 are moved to the destination 1200. Often not helpful when going to For example, a user who has not been to “D Hotel Tokyo” shown in Note 1304 or a user who does not know “D Hotel Tokyo” may not be able to find the facility shown in Note 1304. May not be helpful when heading to destination 1200.

  Therefore, in the map display system 1 according to the present embodiment, for example, as shown in FIG. 2B, a map note indicating a facility that the user has visited in the past or a facility that has searched for a name is displayed. The map 2000 is displayed on the terminal device 10. That is, when the user has visited or searched for facilities such as “ABC Super”, “XX Sports”, “XX Fruit and Vegetable Shop” included in the display range of the map 2000 , Notes 1401 to 1403 are displayed. Accordingly, the user can easily go to the destination 1200 using the map 2000 with reference to the notes 1401 to 1403 indicating the facilities that the user is familiar with. In other words, in the map display system 1 according to the present embodiment, a map note based on the user's past action history and search history is displayed on the map, which is helpful when the user heads to the destination ( Map notes can be provided (which are likely to be helpful).

  In addition, at this time, as shown in FIG. 2B, for example, when a note 1305 displayed in accordance with the scale is overlapped with a note 1403 displayed based on the user's behavior history or search history, the note 1403 Is displayed with priority. This is because the map note displayed based on the user's behavior history and search history is often used as a reference when heading to the destination rather than the map note normally displayed according to the scale of the map.

  Although not shown in the map 1000 and the map 2000 shown in FIGS. 2A and 2B, a route (route) from the current location 1100 to the destination 1200 may be displayed. .

<Hardware configuration>
Next, the hardware configuration of the map display system 1 according to the first embodiment will be described with reference to FIG. FIG. 3 is a hardware configuration diagram of an example of the map display system according to the first embodiment.

The GPS receiver 108 receives current position information of the terminal device 10 from a GPS satellite.

  The server device 20 may be configured to connect and use the input device 105 and / or the display device 106 when necessary. For example, when a smartphone or a tablet terminal is used as the terminal device 10, the input device 105 is realized by a touch panel that can detect tap coordinates (touch coordinates) on the screen displayed on the display device 106 instead of a keyboard or a mouse. May be.

  The terminal device 10 and the server device 20 included in the map display system 1 according to the present embodiment can implement various processes as described later by having the above hardware configuration.

<Functional configuration>
Next, the functional configuration of the map display system 1 according to the first embodiment will be described with reference to FIG. FIG. 4 is a functional block diagram of an example of the map display system according to the first embodiment.

≪Terminal device≫
The terminal application 11 of the terminal device 10 includes an operation receiving unit 12, a position information acquisition unit 13, and a display control unit 14 as main functional units. Further, the terminal application 11 of the terminal device 10 uses the user ID 15.

  The operation receiving unit 12 is realized by the CPU 101, the input device 105, and the like, for example, and receives an input operation from the user.

  The position information acquisition unit 13 is realized by, for example, the CPU 101, the GPS reception device 108, and the like, and acquires the current position information of the terminal device 10.

  The display control unit 14 is realized by the CPU 101, the display device 106, and the like, for example, and causes the display device 106 to display a map based on the display data received from the server device 20.

  The user ID 15 is information that is stored in, for example, the storage device 104 and uniquely identifies the user of the terminal device 10 in the map display system 1. The user ID 15 only needs to be information that can uniquely identify the user in the map display system 1. For example, a telephone number or an e-mail address may be used.

≪Server device≫
The server program 21 of the server device 20 includes a map data acquisition unit 22, an annotation data acquisition unit 23, an overlap determination unit 24, and a display data generation unit 25 as main functional units. The server program 21 of the server device 20 uses a map DB 31, an annotation DB 32, a search history DB 33, and an action history DB 34.

  The map data acquisition unit 22 is realized, for example, by the CPU 101 or the like, and acquires map data corresponding to the display request from the map DB 31 in response to the map display request received from the terminal device 10. The map data is data for drawing a map, details of which will be described later.

  The annotation data acquisition unit 23 is realized by, for example, the CPU 101 or the like, and acquires annotation data corresponding to the display request from the annotation DB 32 in response to the map display request received from the terminal device 10. The note data acquisition unit 23 acquires note data from the note DB 32 based on a search history table 33D and an action history table 34D stored in a search history DB 33 and an action history DB 34 described later. Note data, which will be described in detail later, is data for drawing a map note displayed on a map.

  The overlap determination unit 24 is realized by the CPU 101, for example, and determines whether or not at least a part of the display area of the map note overlaps with each other for the map note drawn by the note data.

  The display data generation unit 25 is realized by the CPU 101, for example, and generates display data for displaying a map on the terminal device 10 based on the map data and the annotation data.

  The map DB 31 stores map data for drawing a map. Map data is categorized by display type, such as sections of green spaces, rivers, roads, railroads, prefectures, etc., for each scale, and is managed with data in which latitude and longitude are divided into known mesh shapes. ing. Here, the map data classified for each type of display target is displayed by being drawn for each mesh on a layer predetermined for each type according to the scale. Therefore, the map displayed on the terminal device 10 is displayed by combining and overlapping one or more mesh-like layers each drawn with data classified for each type of display target.

  The note DB 32 stores note data for drawing a map note on a map. In the annotation data, the name of the facility displayed as a map note, the latitude / longitude for displaying the map note, the attribute information of the facility indicated by the map note, and the like are stored in association with each other. Here, the facility attribute information is information indicating the type of facility indicated by the map note, and includes, for example, “station”, “tourist facility”, “accommodation facility”, “commercial facility”, and the like. The annotation data is drawn on a predetermined mesh-like layer in the same manner as the map data described above. Therefore, the map note on the map displayed on the terminal device 10 is displayed by combining and overlaying one or more mesh-like layers on which the annotation data is drawn on the mesh-like layer drawn on the basis of the map data. Is done.

  The search history DB 33 stores a search history table 33D in which a search history for each user is stored. The search history table 33D stores a history in which a user searches for a facility name or the like on a map using the terminal application 11, and has a data configuration as shown in FIG. 5, for example. That is, the search history table 33D has data items such as “search facility”, “location information”, “attribute information”, and “number of searches” for each user ID. Here, “search facility” is the name of the facility searched by the user, and “location information” is the latitude and longitude of the facility. Further, “attribute information” is the type of facility and is as described above. Furthermore, the “number of searches” is the number of times the user has searched for the facility. Thus, in the search history table 33D, information on facilities on the map searched by the user using the terminal application 11 is managed as a history for each user.

  The search history table 33 </ b> D is created by transmitting the name of the facility to the server device 20 each time the user searches for the name of the facility using the terminal application 11 of the terminal device 10. That is, when the server device 20 receives the name of the facility related to the search from the terminal device 10, the server device 20 creates it by associating the location information, attribute information, and the like with the name of the facility.

  The action history DB 34 stores an action history table 34D in which an action history for each user is stored. The behavior history table 34D stores a history such as the names of facilities on a map visited by the user with the terminal device 10 held therein, and has a data configuration as shown in FIG. 6, for example. That is, the behavior history table 34D has data items such as “visit facility”, “position information”, “attribute information”, “visit count”, “total time”, and the like for each user ID. Here, “visit facility” is the name of the facility on the map visited by the user, and “location information” is the latitude and longitude of the facility. The “attribute information” is the type of the facility and is as described above. “Number of visits” is the number of times the user has visited the facility, and “total time” is the total time the user stayed at the facility. Thus, in the behavior history table 34D, information on facilities on the map visited by the user with the terminal device 10 is managed as a history for each user.

  The action history table 34D is created based on the position information of the terminal device 10 transmitted from the user's terminal device 10. That is, the server device 20 receives the position information from the user terminal device 10 every predetermined time, and when the received position information is within a predetermined range, the server device 20 has a predetermined position in the vicinity of the respective position information. It is determined that the user has visited the facility. And the server apparatus 20 produces by associating the name of the said facility, the attribute information of the said facility, etc. with the latitude and longitude of the facility determined that the user visited.

  In the following description, it is assumed that the search history table 33D and the action history table 34D are created in advance.

<Details of processing>
Next, details of processing of the map display system 1 according to the first embodiment will be described with reference to FIGS. 7 to 9.

≪Map display process flow≫
First, the flow of map display processing according to the first embodiment will be described. FIG. 7 is an example sequence diagram illustrating a flow of map display processing according to the first embodiment.

  In step S <b> 11, the operation reception unit 12 of the terminal device 10 receives an operation for displaying a map performed by the user using the terminal application 11.

  Here, the operation for displaying the map is, for example, that the user designates a desired destination and the scale of the map to be displayed by using the terminal application 11 and determines a route (route) from the current location to the destination. For example, an operation for requesting display of a map including it. Further, for example, an operation in which the user uses the terminal application 11 to specify a map scale and request display of a map around the current location.

  In step S <b> 12, the position information acquisition unit 13 of the terminal device 10 acquires position information (position information of the current location) of the terminal device 10. Then, the terminal application 11 of the terminal device 10 transmits a display request including the acquired location information of the current location, the scale specified in the above step S11, and the user ID 15 of the terminal device 10 to the server device 20.

  If the scale is not specified in step S11, the display request may include a predetermined scale (default scale). Further, when the destination is specified in step S11 described above, the name of the destination, position information indicating the destination, etc. may be included in the display request.

  In step S <b> 13, when the server program 21 of the server device 20 receives the display request described above from the terminal device 10, the server program 21 generates display data based on the display request. The display data generated here is data for causing the terminal device 10 to display a map including a map note based on the user's behavior history and search history. The display data generation process will be described later.

  In step S <b> 14, when the server program 21 of the server device 20 generates display data, the server program 21 transmits a display response including the display data to the terminal device 10.

  In step S15, when receiving the display response described above from the server device 20, the display control unit 14 of the terminal device 10 causes the display device 106 to display a map based on the display data included in the display response. That is, at this time, the display device 106 of the terminal device 10 displays a map 2000 as shown in FIG. 2B (that is, a map including a map note based on the user's behavior history and search history).

≪Display data generation processing≫
Next, the display data generation process in step S13 will be described. FIG. 8 is a flowchart of an example of display data generation processing according to the first embodiment.

  In step S21, when receiving the display request from the terminal device 10, the map data acquisition unit 22 of the server device 20 receives the map data from the map DB 31 based on the position information (latitude / longitude) and the scale included in the display request. get. More specifically, for example, when displaying a map around the current location, the map data acquisition unit 22 is map data corresponding to the scale included in the display request, and the position information included in the display request is displayed. Map data of a mesh including and a predetermined number of meshes around the mesh are acquired. The map data acquired here is stored in a memory such as the RAM 103, for example.

In step S22, the note data acquisition unit 23 of the server device 20 acquires note data from the note DB 32 based on the search history table 33D and the action history table 34D (note data acquired here is referred to as “first note data”). It represents.) More specifically, the first annotation data is acquired as follows.
(1) The latitude / longitude range of the map data acquired in step S21 is specified. Here, it is assumed that the specified latitude range is A _{1 to} A ₂ and the longitude range is B _{1 to} B ₂ . That is, the latitude / longitude of the upper left corner of the map data acquired in step S21 is (A ₁ , B ₁ ), the latitude / longitude of the upper right corner is (A ₂ , B ₁ ), and the latitude / longitude of the lower left corner is (A ₁ , B ₂ ), and the latitude and longitude of the lower right corner are (A ₂ , B ₂ ).
(2) Referring to the search history table 33D and action history table 34D of the user ID 15 included in the display request, the position information included in the latitude / longitude range specified in (1) above is acquired. That is, position information whose latitude range is A _{1 to} A ₂ and whose longitude range is B _{1 to} B ₂ is acquired.
(3) The annotation data displayed in the latitude / longitude of the position information acquired in (2) above is acquired from the annotation DB 32. The note data acquired in this way is first note data indicating a facility that the user has visited in the past or a facility that has been searched for a name in the past. The first annotation data acquired here is stored in a memory such as the RAM 103, for example.

  In (3) above, the note data acquisition unit 23 acquires the first note data based on the “number of searches” in the search history table 33D, the “number of visits” and the “total time” in the behavior history table 34D. May be. For example, the note data acquisition unit 23 is note data displayed in the latitude / longitude of the position information acquired in (2) above, and the “search count” in the search history table 33D is “10 times” or more. The annotation data may be acquired as the first annotation data. Similarly, for example, the note data acquisition unit 23 is note data displayed in the latitude / longitude of the position information acquired in (2) above, and the “visit count” in the action history table 34D is “5 times”. Thus, note data whose “total time” is “30h” or more may be acquired as the first note data. As a result, for example, note data indicating facilities that have been visited only once or facilities that have been searched only once can be excluded, and facilities that are more familiar to the user (facility that has been visited multiple times) Or the first note data indicating a facility that has been searched a plurality of times).

  In step S23, the overlap determination unit 24 of the server device 20 includes the first annotation data acquired in step S22 described above that are displayed at least partially overlapping each other when displayed on the map. It is determined whether or not. If there is first annotation data displayed at least partially overlapping each other, the process proceeds to step S24, whereas if there is no first annotation data displayed overlapping at least one part, the process proceeds to step S25.

  In step S24, the display data generation unit 25 of the server device 20 determines, based on the search history table 33D and the action history table 34D, the first note data determined to be displayed at least partially overlapping each other. Delete one of them. More specifically, for example, as shown in FIG. 9A, when the first note 1402 and the first note 1405 are displayed so as to overlap each other when displayed on the map, one of the maps is displayed. The first annotation data corresponding to the annotation is deleted from a memory such as the RAM 103, for example. Which of the first note data is deleted at this time depends on “attribute information” and “number of searches” in the search history table 33D, “attribute information” and “visit count” in the action history table 34D, etc. It may be determined based on.

  That is, for example, the “number of searches” in the search history table 33D of the first note data for displaying the first note 1402 and the search history table of the first note data for displaying the first note 1405 It is only necessary to compare the “number of searches” in 33D and delete the one with the smaller number of searches. Similarly, for example, the first note data having a smaller “visit count” in the action history table 34D may be deleted, or the first note data having a smaller “total time” may be deleted. .

  Further, referring to the “attribute information” in the search history table 33D and the action history table 34D, any one of them is given according to the priority order such as “station”> “tourist facility”> “accommodation facility”> “commercial facility”. One of the first note data may be deleted.

  As described above, when there is the first note data that is displayed at least partially overlapping each other, the first note data indicating the facility considered to be more familiar to the user is preferentially displayed. You can do it.

In step S25, the note data acquisition unit 23 of the server device 20 acquires note data from the note DB 32 based on the map data acquired in step S21 (note data acquired here is referred to as “second note data”). It represents.) More specifically, the second annotation data is acquired as follows.
(1) The annotation data of the map note displayed in the latitude / longitude range of the map data specified in step S22 is acquired. The annotation data acquired here is stored in a memory such as the RAM 103, for example.
(2) With respect to the note data held in the memory, the overlap determining unit 24 determines whether or not there is note data that is displayed so that at least some of them overlap each other. When there is no note data displayed at least partially overlapping each other, the note data held in the memory becomes “second note data”.
(3) On the other hand, when it is determined by the overlap determination unit 24 that there is note data displayed at least partially overlapping each other, one of the note data is deleted. That is, “attribute information” associated with note data displayed at least partially overlapping each other is referred to, for example, “station”> “tourist facility”> “accommodation facility”> “commercial facility”>. One of them is deleted according to the priority order. In this way, the annotation data held in the memory after deleting any one of the annotation data displayed to overlap each other becomes “second annotation data”.

  In step S <b> 26, the overlap determination unit 24 of the server device 20 has the first annotation data and the second annotation data displayed at least partially overlapping each other when displayed on the map. Determine whether or not. If there is the first note data and the second note data displayed at least partially overlapping each other, the process proceeds to step S27, while at least the first note data and the second note data displayed overlapping each other. If no exists, the process proceeds to step S28.

  In step S <b> 27, the display data generation unit 25 of the server device 20 deletes the second annotation data determined to be displayed so that at least a part of the first annotation data overlaps with each other from the memory. More specifically, for example, as shown in FIG. 9B, at least a first note 1403 displayed by the first note data and a second note 1305 displayed by the second note data are at least If a part of the annotation is displayed, the second annotation data is deleted. That is, the map note displayed by the first note data is displayed with priority over the map note displayed by the second note data. As a result, a map note familiar to the user is displayed on the map.

  Here, in step S27, the first data is displayed unconditionally preferentially for the first note data and the second note data displayed at least partially overlapping each other. Not limited. For example, referring to “attribute information” of the first note data and “attribute information” of the second note data displayed at least partially overlapping each other, for example, “station”> “tourist facility”> “accommodation facility” Any one of them may be deleted in accordance with a priority order such as “>“ commercial facility ”>.

  In step S28, the display data generation unit 25 of the server device 20 superimposes the layer in which the first note data and the second note data are drawn on the layer in which the map data acquired in step S21 is drawn. Display data is generated. Thereby, in the map display system 1 according to the present embodiment, a map (for example, the map 2000 shown in FIG. 2B) on which a map note for reference of the user is displayed based on the user's behavior history and search history. Can be displayed.

[Second Embodiment]
Next, the map display system 1 according to the second embodiment will be described. The map display system 1 according to the second embodiment is different from the first embodiment in that display data generation processing is performed in the terminal device 10 based on the map data and the annotation data acquired in the server device 20.

≪Map data and note data acquisition process≫
Next, the map data and note data acquisition process in step S31 will be described. FIG. 14 is a flowchart of an example of map data and note data acquisition processing according to the second embodiment.

  In step S41, the map data acquisition part 22 of the server apparatus 20 will receive map data from map DB31 based on the positional information (latitude / longitude) and scale contained in the said display request, if a display request is received from the terminal device 10. FIG. get. That is, this is the same processing as step S21 in FIG.

In step S42, the note data acquisition unit 23 of the server device 20 acquires note data from the note DB 32 based on the map data acquired in step S21. More specifically, note data is acquired as follows.
(1) The latitude / longitude range of the map data acquired in step S41 is specified. Here, it is assumed that the specified latitude range is A _{1 to} A ₂ and the longitude range is B _{1 to} B ₂ . That is, the latitude / longitude of the upper left corner of the map data acquired in step S41 is (A ₁ , B ₁ ), the latitude / longitude of the upper right corner is (A ₂ , B ₁ ), and the latitude / longitude of the lower left corner is (A ₁ , B ₂ ), and the latitude and longitude of the lower right corner are (A ₂ , B ₂ ).
(2) The annotation data of the map annotation displayed in the latitude / longitude range of the map data specified in (1) above is acquired.

  Thus, in this embodiment, the server apparatus 20 acquires map data and annotation data of position information included in the latitude / longitude range of the map data in response to a display request from the terminal apparatus 10. .

≪Display data generation processing≫
Next, the display data generation process in step 33 will be described. FIG. 15 is a flowchart of an example of display data generation processing according to the second embodiment.

  In step S <b> 51, when receiving the display response from the server device 20, the terminal application 11 of the terminal device 10 stores the map data and the note data included in the display response in a memory such as the RAM 103.

In step S52, the display data generation unit 25 of the terminal device 10 acquires note data from the memory based on the search history table 33AD and the action history table 34AD (note data acquired here is referred to as “first note data”). Represent.) More specifically, the first annotation data is acquired as follows.
(1) The latitude / longitude range of the received map data is specified. Here, it is assumed that the specified latitude range is A _{1 to} A ₂ and the longitude range is B _{1 to} B ₂ .
(2) With reference to the search history table 33AD and the action history table 34AD, position information included in the latitude / longitude range specified in (1) above is acquired. That is, position information whose latitude range is A _{1 to} A ₂ and whose longitude range is B _{1 to} B ₂ is acquired.
(3) The annotation data displayed in the latitude / longitude of the position information acquired in (2) above is acquired from the memory. The note data acquired in this way is first note data indicating a facility that the user has visited in the past or a facility that has been searched for a name in the past. The first annotation data acquired here is stored in a memory such as the RAM 103, for example.

  As in the case described in step S22 of FIG. 8, in the above (3), the display data generation unit 25 performs “search count” in the search history table 33AD, “visit count” in the action history table 34AD, and “total”. Note data may be acquired based on “time” or the like.

  In step S53, the overlap determination unit 24 of the terminal device 10 includes the first annotation data acquired in step S52 described above that is displayed at least partially overlapping each other when displayed on the map. It is determined whether or not. If there is first note data displayed at least partially overlapping each other, the process proceeds to step S54, whereas if there is no first note data displayed overlapping at least one part, the process proceeds to step S55.

  In step S54, the display data generation unit 25 of the terminal device 10 determines, based on the search history table 33AD and the action history table 34AD, the first note data determined to be displayed at least partially overlapping each other. Delete one of them. This is the same as step S24 in FIG.

  In step S55, the display data generation unit 25 of the terminal device 10 sets the annotation data stored in the memory in step S51 described above as “second annotation data”. In addition, note data excluding the first note data among the note data stored in the memory in step S51 may be “second note data”.

  As described above, in the present embodiment, the first note data and the second note data are acquired from the note data received from the server device 20 based on the user's behavior history and search history managed by the terminal device 10. To do. This eliminates the need to manage the search history DB 33 and the action history DB 34 in the server device 20.
