Further, the update unit 122 updates the branch point icon and the branch point note so as to be displayed in an emphasized manner according to the current location of the user.

  The current location acquisition unit 103 acquires the current location of the user (that is, the latitude and longitude measured by the GPS receiver 18 of the client terminal 10).

  The communication unit 104 transmits various requests to the server device 20 and receives responses to the requests. For example, the communication unit 104 transmits a search request including the search condition to the server device 20 in response to the input receiving unit 101 receiving an input operation for setting the search condition. For example, the communication unit 104 receives a search response to the search request.

  The search response includes, for example, information about the map (map information) displayed by the display unit 112, information about the route on the map (route information), and facility information such as a facility icon or facility note.

  The temporary storage unit 105 stores map information, route information, and facility information included in the search response. Accordingly, the display unit 112 described above displays the route guidance map, the route on the map, the facility icon, and the facility note based on the map information, the route information, the facility icon, and the facility note stored in the temporary storage unit 105. indicate. Similarly, the update unit 122 described above updates the location of the facility icon and the facility note on the map based on the facility icon and the facility note stored in the temporary storage unit 105, and also updates the branch point icon and the like on the map.

<Details of processing example>
Hereinafter, details of a processing example performed by the map display system 1 according to the present embodiment will be described with reference to FIG.

  FIG. 4 is a sequence diagram illustrating an example of the overall processing according to the present embodiment.

  First, the input receiving unit 101 (FIG. 3) of the client terminal 10 receives an input operation for setting a search condition (step S10). Specifically, the input receiving unit 101 receives a search condition such as a destination desired by the user, a departure place, a waypoint, or a combination thereof. That is, when the user performs an operation of inputting the destination or departure location or name, the search condition is set.

  For example, the current location of the user acquired by the current location acquisition unit 103 (FIG. 3) (that is, the latitude and longitude measured by the GPS receiver 18 of the client terminal 10) may be used as the departure location. Moreover, the present location measured based on the reception intensity of wireless LANs, such as Wi-Fi, may be used for a departure place, for example.

  When the communication unit 104 (FIG. 3) of the client terminal 10 receives an input operation for setting search conditions by the input receiving unit 101, the communication unit 104 transmits a search request to the server device 20 (step S11). The search request includes the search condition set in step S10.

  When the search request is received by the communication unit 203 (FIG. 3), the search processing unit 201 (FIG. 3) of the server device 20 searches for a route based on the search condition included in the search request (step S12). That is, the search processing unit 201 searches for a route from the departure place to the destination included in the search condition, and acquires route information as a search result. When a transit point is set in the search condition, the search processing unit 201 searches for a route from the departure point to the destination set by the search condition and passing through the transit point. .

  Subsequently, the information acquisition unit 202 of the server device 20 searches for a guidance facility (step S13). Specifically, the information acquisition unit 202 first searches for a facility serving as a guidance facility in the vicinity of the route and the searched location, and maps information corresponding to the retrieved route and facility information related to the guidance facility To get. Specifically, if there is a landmark building around the searched route, the information acquisition unit 202 searches for such a building as a guidance facility and acquires facility information related to the guidance facility.

  In particular, if there is a facility at a corner or the like, the map display system 1 can display a guidance facility that informs the user of the corner. When such a guidance facility is displayed, the user can easily recognize where the corner is. That is, if the user proceeds with the guide facility as a landmark, the user can proceed without hesitation even if there is a corner or the like.

  Next, the communication unit 203 of the server device 20 transmits a search response to the search request in step S11 to the client terminal 10 (step S14). Note that the search response includes route information searched by the search processing unit 201, map information acquired by the information acquisition unit 202, facility information related to the guidance facility, and the like.

  First, when the display processing unit 102 of the client terminal 10 receives a search response by the communication unit 104 (step S14), the facility information, map information, and route information related to the guidance facility included in the search response are stored in the temporary storage unit 105. Remember me.

  Based on the map information, route information, and facility information stored in the temporary storage unit 105, the display processing unit 102 of the client terminal 10 determines an arrangement position for arranging facility information and the like related to the guidance facility (step S15). .

  Specifically, first, the display processing unit 102 specifies a map to be displayed to the user based on the map information. Next, the display processing unit 102 specifies a location serving as a route on the map based on the route information. In this way, the map to be displayed and which road on the map is the route are specified.

  Then, the display processing unit 102 displays the facility information relating to the route and the guidance facility located around the route. For example, when there is a building to be a store near the route, the display processing unit 102 arranges facility information such as an icon indicating the store name and the store type on the map. Note that the information indicating the facility arranged on the map may be a note, an icon, or a combination thereof.

  The facility information related to the guidance facility may be arranged so as to be displayed in a predetermined color, for example, so as to be easily distinguished from other facilities when the user views the map.

  When the arrangement position where the facility information related to the guidance facility is arranged, that is, when step S15 is performed, for example, the following information is generated. Hereinafter, an example of the processing result of step S15 will be described with reference to FIG.

  FIG. 5 is a diagram illustrating an example of an arrangement result of facility information and the like related to the guidance facility according to the present embodiment. The illustrated example is an example in which each piece of information is arranged on a map indicated by the map information INFMP as illustrated. Specifically, the map information INFMP shown in the figure shows a map in which a part of the area from the starting point STPNT to the destination is enlarged.

  First, on the map, as shown in the figure, the route INFRT is displayed in a predetermined color, for example, based on the route information. Then, around the route INFRT, as shown in the figure, the guidance facility BLCY is displayed on the map, for example, in a predetermined color. In particular, when there is a turning corner CRNR, it is desirable to display the guidance facility BLCY as shown in the figure.

  The guidance facility BLCY may be displayed by another emphasis method, a facility name, an icon indicating a facility, or the like.

  Returning to FIG. 4, the identification processing unit 106 (FIG. 3) of the client terminal 10 identifies the first display area and the second display area (step S16). Hereinafter, the map shown in FIG. 6 will be described as an example.

  FIG. 6 is a diagram showing a specific example of the first display area and the second display area according to the present embodiment. First, step S15 is performed, and it is assumed that the arrangement position where the facility information and the like related to the guidance facility are arranged is determined on the map as illustrated.

  Then, the identification processing unit 106 identifies a range within a predetermined distance from the route INFRT as the first display area VE1ST. Specifically, in the illustrated example, a range within a predetermined distance DIS from the route INFRT is specified as the first display region VE1ST. The predetermined distance DIS is a value that can be set in advance.

  Next, in addition to the range within the predetermined distance DIS from the route INFRT, the specification processing unit 106 further specifies facility information such as a facility name in the first display area VE1ST. Specifically, in the illustrated example, first, a polygon indicating the guidance facility BLCY is arranged on the map. And the specific process part 106 also specifies the display range VECY in which the facility name of each guidance facility BLCY is displayed to the 1st display area VE1ST. Note that the display range VECY is not limited to a note indicating a facility name or the like as illustrated, and may include facility information in general relating to a guidance facility such as an icon.

  In this way, the range within the predetermined distance DIS from the route INFRT and the display range VECY in which the facility information of the guidance facility BLCY is displayed are specified in the first display region VE1ST. In other words, in addition to the range in which the guidance facility BLCY is displayed, the specific processing unit 106 also excludes facility information such as the facility name related to the guidance facility BLCY from the masked range in the subsequent mask processing, The first display area VE1ST is specified so that the facility information and the like can be easily viewed. In addition to the range within the predetermined distance DIS from the route INFRT and the display range VECY in which the facility information of the guidance facility BLCY is displayed, the periphery of the display range VECY is further displayed in the first display area VE1ST as shown in the figure. It may be specified. The range around the display range VECY can be arbitrarily set. On the other hand, the identification processing unit 106 identifies a range other than the first display area VE1ST as the second display area VE2ND.

  In the figure, the first display area VE1ST is shown in white, and the second display area VE2ND is shown in gray.

  Returning to FIG. 4, the mask processing unit 107 (FIG. 3) of the client terminal 10 masks the second display area (step S17). That is, the mask processing unit 107 masks the second display area specified in step S16.

  The mask process is a process for making the second display area darker than the first display area, for example. That is, the mask process is a process of performing so-called grayout. When such mask processing is performed, the first display area stands out from the second display area, and the first display area becomes easy to see.

  Next, the display processing unit 102 (FIG. 3) of the client terminal 10 displays route guidance. For example, the following screen as shown in FIG. 7 is displayed.

  FIG. 7 is a diagram illustrating an example of a screen displayed in route guidance. Further, the illustrated example is an example in which a mask for graying out the second display region VE2ND is performed. As described above, when the second display area VE2ND is masked, the route guidance is displayed in a state where the guidance facility specified in the first display area VE1ST and the facility information related to the guidance facility are outlined. Thus, when the route guidance is displayed, it is easy for the user to see the route and facility information displayed in the first display area VE1ST on the map. That is, the map display system 1 can display a map that is easy for the user to see in the route guidance, for example, by performing processing as shown in FIG.

  FIG. 8 is a flowchart showing an example of the overall processing according to the present embodiment.

  First, the map display system 1 sets search conditions such as a departure place and a destination (step S20). Next, the map display system 1 searches for a route that the user can move from the departure point to the destination (step S21).

  Then, the map display system 1 acquires route information indicating the route searched in step S21 (step S22). Moreover, the map display system 1 acquires map information indicating the periphery of the route searched in step S21 (step S22). Furthermore, the map display system 1 searches for the guidance facility on the route searched in step S21, and acquires facility information of the guidance facility (step S22).

  Subsequently, the map display system 1 specifies the first display area and the second display area (step S23). Specifically, the first display area is specified so that the area including the display range of the facility information related to the route and the guidance facility is a range. Then, the map display system 1 specifies an area other than the first display area as the second display area.

  Next, the map display system 1 masks the second display area (step S24). Then, the map display system 1 displays route guidance by combining the first display area and the masked second display area (step S25).

  Each process may be performed in a distributed, parallel or redundant manner by different devices.

<Other embodiments>
The client terminal 10 displays a facility icon or facility note in the vicinity of a branch point (for example, a T-junction or an intersection) included in the route according to the current location of the user (that is, the current location where the client terminal 10 is located). You may display it by emphasizing (for example, expansion, blinking, changing a color, or a combination thereof).

  In this way, the user of the client terminal 10 can proceed in the correct direction (direction of the destination) at the branch point without overlooking the guidance facility existing near the branch point included in the route. It becomes like this. Thereby, the map display system 1 which concerns on this embodiment can provide the route guidance which a user does not get lost in the branch point on maps, such as a T-junction or an intersection.

  Specifically, the map display system 1 displays, for example, as follows in route guidance. Hereinafter, an example of route guidance provided by the map display system 1 according to the present embodiment will be described with reference to FIG.

  FIG. 9 is a diagram illustrating an example of a route guidance screen.

  A route guidance screen 1000 shown in FIG. 9 is a screen on which a route 1103 for traveling from the departure place 1101 to the destination 1102 is displayed. In this example, the route 1103 includes a branch point 1113, a branch point 1123, and a branch point 1133. In the following description, the “branch point” refers to a T-junction or intersection on the map as described above.

  In the route guidance screen 1000, facility icons 1300 to 1700 and facility notes 1800 of various facilities near the route 1103 (that is, along the route 1103) are displayed. Whether a facility on the map is displayed as a facility icon or a facility note is determined in advance according to the facility.

  Here, among the facility icons, a branch point 1113, a branch point 1123, and a facility icon in the vicinity of the branch point 1133 included in the route (for example, a facility icon within a predetermined range from the branch point) are referred to as a “branch point icon”. Also shown. Similarly, among facility notes, facility notes in the vicinity of branch points 1113, 1123, and 1133 included in the route (for example, facility notes within a predetermined range from the branch point) are referred to as “branch point notes”. ". Therefore, among the facility icons 1300 to 1700 and the facility note 1800, the facility icon 1300, the facility icon 1600, and the facility note 1800 are also indicated as “branch icon 1300”, “branch point icon 1600”, and “branch point note 1800”, respectively.

  At this time, when the current location icon 1200 indicating the current location of the user approaches the branch point included in the route, the client terminal 10 according to the present embodiment emphasizes the branch point icon and the branch point note near the branch point. To display. That is, for example, when the current location icon 1200 approaches the branch point 1113 included in the route, the branch point icon 1300 and the branch point note 1800 near the branch point 1113 are enlarged and displayed. For this reason, the user does not overlook the facility near the branch point included in the route, and the location relationship and type of the facility (for example, whether it is a restaurant or a convenience store), name (for example, chain store) Name).

  As described above, when the user approaches a branch point (for example, a T-junction or an intersection) included in the route, the client terminal 10 according to the present embodiment displays an icon or a note indicating a facility near the branch point. Etc. are highlighted. For this reason, according to the map display system 1 which concerns on this embodiment, the situation where a user will go to the wrong direction can be prevented, for example in the branch point included in a path | route. That is, according to the map display system 1 according to the present embodiment, it is possible to provide the user with route guidance that does not hesitate in the vicinity of the branch point.

  The process of emphasizing and displaying icons, notes, and the like as described above is realized as follows, for example.

  The display unit 112 (FIG. 3) acquires map information, route information, and facility information from the temporary storage unit 105. Then, the display unit 112 superimposes a route based on the route information, a current location icon indicating the current location of the user, a facility icon, and a facility note on the map based on the map information, for example, as illustrated in FIG. A route guidance screen 2000 is displayed on the display device 16.

  FIG. 10 is a diagram illustrating an example of display and update of the route guidance screen.

  The current location icon may be acquired from the information storage unit 204 (FIG. 3) of the server device 20 and transmitted to the client terminal 10 in the search response in step S14 (FIG. 4). Ten storage areas (for example, the temporary storage unit 105 (FIG. 3)) may be stored in advance.

  A route guidance screen 2000 shown in FIG. 10A is a screen on which a route 2103 for traveling from the departure location 2101 to the destination 2102 is displayed with the current location of the user as the departure location 2101. The route 2103 includes a branch point 2113, a branch point 2123, and a branch point 2133. On the route guidance screen 2000, a current location icon 2200 indicating the current location of the user is displayed at the same position as the departure location 2101.

  On the route guidance screen 2000, facility icons 2300 to 2700 and facility notes 2800 of facilities existing near the route 2103 are displayed. The facility icon 2300, the facility icon 2600, and the facility note 2800 are also referred to as a “branch point icon 2300”, a “branch point icon 2600”, and a “branch point note 2800”.

  Further, on the route guidance screen 2000, the facility icons 2300 to 2700 are displayed so that they do not overlap the route 2103 and the feet of the facility icons 2300 to 2700 are directed toward the position of the current location icon 2200. In addition, the foot | leg of a facility icon is a triangular projection part which points out the position of the facility which the said facility icon shows.

  As described above, in the map display system 1 according to the present embodiment, when a search condition including a departure place, a destination, and the like is set by the user at the client terminal 10, the display device 16 of the client terminal 10 displays, for example, FIG. A route guidance screen 2000 shown in FIG. At this time, in the route guidance screen displayed on the display device 16 of the client terminal 10, the facility icon indicating the facility existing along the route does not overlap the route, and the foot of the facility icon indicates the current location of the user. It is displayed in the direction.

  That is, in the map display system 1 according to the present embodiment, the facility icon and facility note of the facility (facility along the route) necessary for the user to go to the destination according to the route are displayed on the client terminal 10. To do. On the other hand, in the map display system 1 according to the present embodiment, facility icons of unnecessary facilities that do not exist along the route are not displayed on the client terminal 10. Thereby, when going to the destination, it is possible to prevent a situation where the user overlooks the facility icon or facility note of the necessary facility that is a landmark.

  Next, when the user of the client terminal 10 moves on the route guidance screen 2000 shown in FIG. 10A, the client terminal 10 displays the route guidance screen 2000 on the route guidance screen 3000 shown in FIG. 10B, for example. Update to

  A route guidance screen 3000 shown in FIG. 10B is a screen displayed when the user of the client terminal 10 moves from the position indicated by the departure place 210 to the position indicated by the current location icon 2200. That is, the route guidance screen 3000 shown in FIG. 10B is displayed when the current position of the user approaches the branch point 2113 included in the route 2103 (when reaching a predetermined range from the branch point 2113). It is a screen.

  At this time, on the route guidance screen 3000 shown in FIG. 10B, the feet of the facility icons 2300 to 2700 are displayed so as to face the position of the current location icon 2200, and the branch point icon 2300 near the branch point 2113 and A branch point note 2800 is enlarged and displayed. Thereby, when the user of the client terminal 10 approaches the branch point 2113, the user can easily recognize the facility near the branch point 2113 without overlooking the facility, and grasp the positional relationship of the facility. Will be able to.

  Therefore, the map display system 1 according to the present embodiment highlights and displays a facility near the branch point (for example, a T-junction or an intersection) when the user approaches the branch point. It is possible to provide route guidance in which the user does not get lost in terms of points.

  In the route guidance screen 3000 shown in FIG. 10B, the case where the facility icon is enlarged and displayed is shown as an example of the highlight display, but the present invention is not limited to this. For example, the highlighting may be a blinking facility icon, a dynamic animation display, a color change, or a combination thereof.

  In the present embodiment, the facility icons and facility notes along the route are acquired from the information storage unit 204. However, the present invention is not limited to this. For example, all the facilities on the map based on the map information corresponding to the searched route are used. Icons and facility notes may be obtained. In this case, only the facility icon and the facility note along the route may be displayed on the client terminal 10 in step S18 (FIG. 4).

  Subsequently, when the route guidance screen is updated by the movement of the user (ie, in the route guidance screen 2000 shown in FIG. 10A, for example, the route guidance screen 3000 shown in FIG. Will be described. The route guidance screen update process described below is executed every predetermined time (for example, several milliseconds to several seconds).

  First, the current location acquisition unit 103 (FIG. 3) of the client terminal 10 acquires the current location of the user (that is, the latitude and longitude measured by the GPS receiver 18 of the client terminal 10).

  Next, the display processing unit 102 (FIG. 3) of the client terminal 10 updates the position (display position) of the current location icon indicating the current location of the user on the map by the update unit 122 (FIG. 3). That is, the update unit 122 updates the display position of the current location icon on the map so as to correspond to the current location acquired in the process of acquiring the user's current location.

  Next, the display processing unit 102 of the client terminal 10 causes the updating unit 122 to update the location of the facility icon displayed on the map according to the updated location of the current location icon. Here, the update of the display position of the facility icon will be described with reference to FIG.

  FIG. 11 is a diagram for explaining an example of updating the display position of the facility icon. As shown in the drawing, when the current location icon P is at the position Q, the display position of the facility icon A indicating the facility R is displayed at such a position that the foot of the facility icon A faces the direction of the position Q.

  At this time, when the current location icon P moves from the position Q to the position Q ′, the display position of the facility icon A indicating the facility R is updated so that the foot of the facility icon A is in the direction of the position Q ′. As a result of updating the display position of the facility icon A, when the facility icon A overlaps the route, for example, the display position of the facility icon A is updated by rotating the facility icon A within a range that does not overlap the route.

  Thus, the display position of each facility icon on the map is updated so that the foot of each facility icon faces the current location icon. Thereby, since the foot | leg of each facility icon is displayed radially centering on a present location icon, the route guidance which becomes easy to grasp | ascertain the positional relationship of each facility can be provided now.

  Subsequent to the update of the location of the facility icon as described above, the display processing unit 102 of the client terminal 10 causes the update unit 122 to add a branch point icon or a branch point note within a predetermined range from the position of the updated current location icon. It is determined whether or not there is. That is, the update unit 122 determines whether or not the position of the updated current location icon has approached the branch point of the route.

  When it is determined that there is a branch point icon or a branch point note within a predetermined range from the position of the current location icon, the update unit 122 highlights the branch point icon or / and the branch point note within the predetermined range. Update to That is, the update unit 122 updates the display size of the branch point icon and the branch point note so that the branch point icon and the branch point note within a predetermined range from the current location icon are displayed in an enlarged manner, for example.

  Note that, as described above, the mode of highlighting the branch point icon and the branch point note updated by the update unit 122 is not limited to the enlarged display. For example, the update unit 122 may update so that a branch point icon or a branch point note blinks or may be updated so as to be dynamically displayed by animation. As described above, the highlighting mode may be a mode in which a branch point icon or a branch point note is displayed prominently, and various display objects may be mentioned.

  Further, the update unit 122 may change the highlighting mode of the branch point icon and the branch point note depending on the position of the current location icon. For example, when the current location icon and the branch point icon are within 500 m, the branch point icon is displayed in double size, while when the current location icon and the branch point icon are within 100 m, the branch point is displayed. You may make it display a dot icon by a 4 times magnitude | size.

  Next, the display processing unit 102 of the client terminal 10 causes the display unit 112 to display route guidance based on the updated current location icon, facility icon, and facility note. That is, the display unit 112 displays the updated current location icon, facility icon, and facility note superimposed on the map.

  In addition, when the map information corresponding to the current location acquired by the above processing is not stored in the temporary storage unit 105, the client terminal 10 may request the server device 20 to acquire the map information corresponding to the current location. That is, when the user moves out of the map based on the map information stored in the temporary storage unit 105, the map information corresponding to the current location after the movement may be acquired from the server device 20.

  As described above, the client terminal 10 according to the present embodiment displays the facility icon so that the foot of the facility icon faces the direction of the current position of the user according to the movement of the user of the client terminal 10, and Highlight facility icons and facility notes. As a result, the client terminal 10 according to the present embodiment can easily grasp the positional relationship of each facility on the map, and the route guidance does not cause the user to get lost at a branch point such as a T-junction or an intersection. Can be provided. Here, another example of the route guidance screen provided by the map display system 1 according to the present embodiment will be described with reference to FIG.

  FIG. 12 is a diagram illustrating another example of the route guidance screen.

  The route guidance screen 4000 shown in the figure displays a route 2103 for heading from the departure place 2101 to the destination 2102 as in the route guidance screen 2000 shown in FIG. Similarly, facility icons 2300 to 2700 indicating facilities existing in the vicinity of the route 2103 and a facility note 2800 are displayed.

  At this time, in the route guidance screen 4000 shown in FIG. 12, the house shape frame 2310 of the facility indicated by the branch point icon 2300, the house shape frame 2610 of the facility indicated by the branch point icon 2600, and the house shape frame 2810 of the facility indicated by the facility note 2800 are displayed. Is displayed. Thus, the route guidance screen 4000 displays the house frame of the facility near the branch point of the route.

  Thereby, the user can know the shape of the facility along with the positional relationship of the facility indicated by the branch point icon and the branch point note. For this reason, since the shape of the facility can be grasped in addition to the positional relationship of the facility at a branch point such as a T-junction or an intersection, the user does not get lost at a branch point such as a T-junction or an intersection. Route guidance can be provided.

  In the route guidance screen 4000 shown in FIG. 12, no branch point icon or branch point note is displayed near the branch point 2123 included in the route 2103. This is because there is no facility where facility icons or facility notes are displayed near the branch point 2123. In such a case, for example, when a general house or the like is near the branch point 2123 included in the route 2103, a house frame such as the general house may be highlighted.

  Thereby, for example, even when a facility (for example, a commercial facility) in which a facility icon or facility note is displayed does not exist near the branch point, the user can refer to a house frame such as a general house. Therefore, it is possible to provide route guidance without causing the user to get lost.

  In the display shown in FIGS. 9 to 12, a region other than the facility information related to the route and the guidance facility may be masked.

<Modification>
Note that the mask processing is not limited to the gray-out processing as illustrated in FIG. For example, the mask process may be a process that brightens the first display area. In addition, the mask process may be, for example, a process for changing the transmittance at which the second display area is displayed, a process for filling the second display area with a predetermined color, or the second display area from any end. Processing that displays in gradation may also be used. In other words, the mask process may be a process for changing to another display such as changing the brightness of the second display area or painting with a predetermined color.

  In addition, the facility information and the route may be search results that differ depending on the moving means of the user, for example. Specifically, for example, the moving means is a vehicle, a walk, a bicycle, a train, or the like. Such a moving means is set by a user operation as a search condition, for example. Then, the server device searches for a route or a guidance facility based on the set moving means. Accordingly, the map display system 1 may display a route or a guidance facility suitable for the moving means in consideration of the moving means used by the user.

  In addition, the first display area and the second display area may not always be constant. For example, the map display system 1 determines whether each of the first display area and the second display area depends on the moving speed of the user, the weather, the time, the attribute of the user, whether it is a corner, whether it is around the destination, or a combination thereof. The range may be changed.

  Specifically, for example, when the moving speed of the user is fast, the first display area may be displayed so as to be narrowed. When the moving speed of the user is fast, the user is often familiar with the geography around the current location. That is, there are many cases where a map of a position considered to be detailed is not hindered even if it is not visible. Therefore, when the moving speed of the user increases, the map display system 1 may change the range to be masked to be enlarged.

  In addition, for example, when the current location is around a corner or approaches the destination, the map display system 1 may change the range to be the first display area.

  In addition, the map display system 1 may change the ranges of the first display area and the second display area in consideration of user attributes and the like. Specifically, the user's attribute is profile information such as height or visual acuity, for example. A user with good vision or a tall user often has a wide viewable range. Thus, with reference to the user's profile, the map display system 1 may be changed to the first display area adapted to each user.

  Note that information such as the user's moving speed, weather, time, or user attributes is acquired from another application installed in the client terminal 10 or the server device 20 in advance, or input by the user in advance. It is the information that is acquired.

  Further, the second display area may not always be masked. For example, the map display system 1 may change the display of the mask depending on whether or not the current position of the user is indoors. Specifically, for example, a display as shown in FIG. 13 may be used.

  FIG. 13 is a diagram illustrating an example of an indoor route guidance screen. The example shown in the figure is an example of a route guidance screen when a user enters a subway station. That is, the current position of the user is in the station and indoors.

  In such a case, the map display system 1 first removes the mask attached to the second display area. Next, as shown in the figure, the map display system 1 masks a building part where the user is present, that is, a part other than a range that is a station facility in this example. As illustrated, the mask range MSK is a location other than the facility where the user is located, that is, a range other than the station building. As described above, the map display system 1 may change the mask range MSK when the user enters the station building.

  Further, the map display system 1 may switch whether to perform masking based on a user operation, a mode, a moving section, or the like. For example, there are cases where a mode for setting a departure point and a destination, and a mode for displaying a route guidance screen to guide a user are separated. For example, as shown in FIG. 7, the route guidance screen is often a display screen that follows the current position of the user.

  Furthermore, a section using a train may be included depending on the route. As described above, in the mode following the current position of the user, or in the section where the train is used, the map display system 1 displays the second display area while masking it, for example, as shown in FIG. On the other hand, for example, when the mode is a mode for setting a departure point and a destination, or while the user is inputting a scrolling operation for changing the screen or a pinching operation for enlarging or reducing the screen. The map display system 1 removes the mask. Thus, the map display system 1 may switch whether to perform masking according to the mode or the like.

<Summary>
As described above, the map display system 1 according to the present embodiment provides route guidance to the destination to the user. In addition, the map display system 1 according to the present embodiment specifies a guide facility existing at a landmark or a corner and displays the guide facility on the map with emphasis or the like as the user progresses along the route.

  Then, the map display system 1 prevents the facility information related to the guidance facility from being masked by the mask in the map display. In this way, the user can easily see the map because the facility information related to the guidance facility is not hidden by the mask when viewing the displayed map.

  Thus, the map display system 1 according to the present embodiment can provide route guidance by displaying the map in an easy-to-view manner.

  In the present embodiment, the facility icon and facility note of the facility near the branch point of the route are highlighted. For example, the types of facilities that highlight the facility icon and facility note may be narrowed down. Thereby, for example, when “convenience store” is set as the type of facility, among the facilities near the branch point of the route, the facility icon or facility note of the facility indicating the convenience store can be highlighted. Become.

  Further, the facility data associated with the corner information indicating that the facility is located at the corner of the branch point is stored in the information storage unit 204 of the server device 20, and the information acquisition unit 202 of the server device 20 Based on the corner information, the facility icon or facility note of the facility at the corner position of the branch point may be acquired from the information storage unit 204. Thereby, the information acquisition unit 202 of the server device 20 can easily acquire the facility icon and facility note of the facility near the branch point based on the corner information.

  In the present embodiment, the user may be able to switch between the route guidance screen 1000 and a route guidance screen having a display mode different from the route guidance screen 1000. Here, the route guidance screen having a different display mode is not limited to a screen in which a branch point note or a branch point icon is highlighted (for example, blinking or animated) in a display mode different from that of the route guidance screen 1000. This includes screens where point notes and branch point icons are not highlighted. Note that the switching operation includes a method in which a user switches a predetermined display component displayed on the screen by a tap operation or the like. This makes it possible to provide a user with a route guidance screen on which facility icons and facility notes near branch points are displayed in various display modes.

  The present invention is not limited to the specifically disclosed embodiments, and various modifications and changes can be made without departing from the scope of the claims.
