Japanese Unexamined Patent Publication No. 2018-31647

By displaying the icon of the landmark facility around the current position and the branch point on the route, the user can easily grasp the current position and the branch point. However, if the facility icon of the type set by the user as a display target also exists around the current position or branch point, the mixture of these makes the landmark facility inconspicuous and makes it difficult for the user to recognize the existence of the landmark facility. There was a problem.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique for increasing the possibility that a user can easily recognize a landmark facility.

In order to achieve the above purpose, the navigation system has a user setting type acquisition unit that acquires a user setting type that is a type of facility set by the user as a display target, and a marker that acquires a predetermined marker facility. In the facility acquisition unit, the map display unit that displays the map including the facility of the user setting type on the display unit, and the attention range of the map, the facility of the user setting type is hidden and the landmark facility is displayed. It is equipped with an internal display control unit.

Further, in order to achieve the above-mentioned purpose, the navigation program is a user setting type acquisition unit for acquiring a user setting type, which is a type of facility set by the user as a display target, and a predetermined marker facility. The mark facility acquisition unit, the map display unit that displays the map including the facility of the user setting type on the display unit, and the facility of the user setting type are hidden and the mark facility is displayed in the attention range of the map. It functions as a display control unit within the range of attention.

That is, in this navigation system and navigation program, the facilities of the user setting type are displayed outside the attention range of the map, but the user setting type is hidden and the landmark facilities are displayed within the attention range. In this case, the landmark facility stands out as compared with the case where the landmark facility and the facility of the user setting type coexist within the range of attention. Therefore, according to this navigation system and navigation program, it is possible to increase the possibility that the user can easily recognize the landmark facility.

(1) Navigation system configuration:
FIG. 1 is a block diagram showing a configuration of a smartphone 10 as a navigation system according to an embodiment of the present invention. The smartphone 10 includes a control unit 20, a recording medium 30, a positioning sensor 41, and a touch panel display 42. The control unit 20 is a computer including a CPU, RAM, ROM, and the like, and executes various programs including the navigation program 21.

The communication unit 40 includes a circuit for communicating with other devices. The control unit 20 can wirelessly communicate with various devices such as a server (not shown) via the communication unit 40. The touch panel display 42 includes a touch sensor that outputs an operation signal corresponding to a user's touch operation to the control unit 20, and a display that displays an arbitrary image based on a video signal output from the control unit 20.

The positioning sensor 41 is a sensor that acquires information necessary for calculating the current position and traveling direction of the smartphone 10, and includes a GNSS (Global Navigation Satellite System) receiver, an acceleration sensor, a gyro sensor, a geomagnetic sensor, and the like. .. The control unit 20 calculates the current position and the traveling direction of the smartphone 10 based on the signal output by the positioning sensor 41. The control unit 20 may correct the current position based on the position information of the base station detected by the communication unit 40.

Map information 30a, user setting information 30b, and landmark facility information 30c are recorded on the recording medium 30. The map information 30a is information used for specifying the position of the smartphone 10 and the facility to be guided, displaying a map, etc., node data indicating the position of a node set on the road, and the shape of the road between the nodes. It includes shape interpolation point data indicating the position of the shape interpolation point for specifying, link data indicating the connection between nodes, facility data indicating facilities existing on the road and its surroundings, and the like. The link data includes sidewalk link data and roadway link data. In the case of pedestrian navigation, sidewalk link data is used. The facility data includes data such as facility icon data according to the location, name, type, building shape, facility type, brand, etc. of the facility. Further, the map information 30a includes topographical data indicating the positions and shapes of the sea, lakes, rivers, mountains, and the like. The user setting information 30b and the landmark facility information 30c will be described later.

The control unit 20 can execute the navigation program 21 having a navigation function to the destination. The navigation program 21 causes the control unit 20 to realize a route search function for searching a route from the current position of the smartphone 10 to a destination input by the user and a route guidance function for guiding the user to proceed on the route. At the time of route guidance, a map near the current position is displayed on the touch panel display 42. In the present embodiment, in order to realize the map display at the time of route guidance, the navigation program 21 includes the user setting type acquisition unit 21a, the mark facility acquisition unit 21b, the map display unit 21c, and the attention range display control unit 21d.

The user setting type acquisition unit 21a is a program module that realizes the function of acquiring the user setting type, which is the type of facility set by the user as a display target, in the control unit 20. The navigation program 21 has a function that allows the user to customize the type of facility displayed by the icon on the map. The facility set as the display target by the user operating the touch panel display 42 is recorded on the recording medium 30 as the user setting information 30b.

For example, in the user setting information 30b, as shown in FIG. 2A, information (display target / non-display target) indicating whether or not to display is targeted for each type of facility is associated with the user setting information 30b. In the present embodiment, as shown in FIG. 2A, the following description will be made assuming that the convenience store, the parking lot, and the restaurant are set as display targets, and the gas station and the bank are set as non-display targets by the user. The control unit 20 refers to the user setting information 30b recorded in this way by the function of the user setting type acquisition unit 21a, and acquires the facility type (user setting type) set as the display target by the user. do. Note that the user setting information 30b shown in FIG. 2A is an example, and when the facility type is hierarchically defined, various hierarchical types may be defined as the user setting type.

The mark facility acquisition unit 21b is a program module that enables the control unit 20 to realize a predetermined function of acquiring a mark facility. In the navigation program 21, a facility (mark facility) that guides the user as a mark at the time of route guidance is predetermined. The landmark facility may be a facility where the user can easily recognize the existence in the real space, or a facility where it is easy to collate the notation on the map with the actual facility. For example, as a landmark facility, it may be assumed that a signboard with a company logo mark, facility name, etc. is posted on the actual facility.

The mark facility information 30c includes information on the facility defined as the mark facility. For example, in this embodiment, as shown in FIG. 2B, five banks (AA bank, BB bank, CC bank, DD bank, EE bank) and four gas stations (FF, GG, HH, II). Company) and three convenience stores (JJ, KK, LL) are included in the landmark facility information 30c as landmark facilities. The landmark facility may be a feature that can be a landmark (famous building, natural sculpture, etc.). Further, the landmark facility may be a facility whose scale is larger than the standard among the facilities existing at the corner of the intersection or the reference distance from the intersection. By the function of the mark facility acquisition unit 21b, the control unit 20 acquires the mark facility with reference to the mark facility information 30c.

The map display unit 21c is a program module that enables the control unit 20 to display a map including facilities of the user setting type on the display unit. The control unit 20 acquires the current position based on the output signal of the positioning sensor 41, and sets the default range including the current position as the display target range of the map on the touch panel display 42. The display target range is determined according to the scale of the map, the map display mode (north up, heading up, etc.), and the like. In the present embodiment, the map is configured to include a plurality of layers such as a background layer, a road layer, a route layer, and an icon layer. The display priority is the background layer, the road layer, the route layer, and the icon layer in ascending order. When images of a plurality of layers overlap, the image of the layer having a high display priority is controlled to be displayed preferentially. The control unit 20 draws a background image of the display target range, an image of the road existing in the display target range, an image of the route to the destination, and the like on the background layer, the road layer, and the route layer of the RAM, respectively. Further, the control unit 20 draws a current position icon indicating the current position on the icon layer.

Further, the control unit 20 acquires a facility located within the display target range based on the facility data, and the facility of the type (user setting type) set as the display target by the user exists in the facility. Judge whether or not. When a facility of a user setting type exists, the control unit 20 draws an icon indicating the type of the facility, a company logo, or the like in the icon layer at a position within the display target range corresponding to the position of the facility.

In the present embodiment, as shown in FIG. 2A, convenience stores, parking lots, and restaurants are user setting types. Therefore, when a convenience store, parking lot, or restaurant exists within the display target range, the control unit 20 Uses the function of the map display unit 21c to draw icons indicating these facilities on the icon layer in a normal display mode.

The attention range display control unit 21d is a program module that realizes the function of displaying the mark facility in the attention range of the map by hiding the facility of the user setting type. The range of attention is a range located within the display target range of the map, and is a range in which the user is expected to pay more attention than other parts in the display target range. In this embodiment, pedestrian navigation is assumed, and the range of attention in pedestrian navigation includes the current position of the smartphone 10 carried by the user, and is a range equal to or less than the predetermined distance centered on the current position ( The entire circumference range).

3A, 3C, and 4A are diagrams showing examples of the positions of roads and facilities existing within the display target range, and FIGS. 3B, 3D, and 4B are shown in FIGS. 3A, 3C, and 4A, respectively. This is a corresponding display example. That is, FIG. 3B shows an example of displaying a map on the touch panel display 42 when each facility exists as shown in FIG. 3A. The same applies to the relationship between FIGS. 3D and 3C, and the relationship between FIGS. 4B and 4A.

In FIGS. 3A, 3C, and 4A, I1 is an icon indicating the current position of the smartphone 10, and the range of the broken line centered on the current position is the range of attention in the present embodiment. In FIG. 3A, there are a restaurant (Ir1), a parking lot (Ip1), and a gas station (Ig) of FF within the attention range, and a convenience store (Ic1) of KK is outside the attention range. It shows that there is a parking lot (Ip2 to Ip5), a restaurant (Ir2), and an AA bank (Ib1).

In this embodiment, convenience stores, parking lots, and restaurants are user setting types (see FIG. 2A). Therefore, the icon drawn on the icon layer by the function of the map display unit 21c is a convenience store of KK. The icons Ic1 are shown, the parking lot icons Ip1 to Ip5, and the restaurant icons Ir1 to Ir2. In the present embodiment, since the gas station and the bank are not user setting types, the icon Ig and the icon Ib1 are not drawn on the map display unit 21c.

By the function of the attention range display control unit 21d, the control unit 20 hides the facility of the user setting type when the facility of the user setting type exists in the attention range. In the case of FIG. 3A, since the restaurant (Ir1) and the parking lot (Ip1), which are facilities of the user setting type, exist within the attention range, the icons Ir1 and the icon Ip1 are deleted in the icon layer.

Further, the control unit 20 displays the mark facility existing in the attention range by the function of the attention range display control unit 21d. In the present embodiment, the landmark facility existing in the range of interest is displayed (highlighted) in a mode that is emphasized more than usual. Specifically, for example, highlighting is performed such that the size of the icon is made larger than the usual mode and the outline of the icon is made thicker. In the case of FIG. 3A, since the gas station (Ig) of FF, which is a marker facility, exists in the attention range, the control unit 20 emphasizes the icon Ig more than usual by the function of the attention range display control unit 21d. Draw on the icon layer.

When the drawing of each layer is completed, the map of the display target range is displayed on the touch panel display 42 according to the display priority based on the drawing data of each layer. As a result, as shown in FIG. 3B, the icon Ig indicating the gas station of FF, which is a landmark facility, is highlighted around the current position icon I1, but the restaurant icon Ir1 and the parking lot icon Ip1 (FIG. 3A). See) is hidden. Therefore, the icon Ig, which is a landmark facility, can be made to stand out, and the possibility that the user can easily recognize the landmark facility can be increased. The user can grasp the current position and the traveling direction based on the icon Ig on the map displayed on the touch panel display 42 and the position of the FF gas station in the real space.

The convenience store (Ic1) of KK is a landmark facility outside the range of attention, but since it is also a user setting type, it is displayed in a normal manner as shown in FIG. 3B. Since the AA bank (Ib1) is out of the range of attention and is not a user setting type, it is not displayed on the touch panel display 42 as shown in FIG. 3B.

FIG. 3C shows a state in which the user has progressed on the route further than the state of FIG. 3A. In the state of FIG. 3C, there are a restaurant (Ir1, Ir2), a convenience store (Ic1) of KK, and a parking lot (Ip3) within the range of attention. Further, outside the range of attention, there are parking lots (Ip1, Ip2, Ip4, Ip5), a restaurant (Ir3), and an AA bank (Ib1).

The control unit 20 draws the icon Ic1 indicating the convenience store of KK, which is a user setting type, the parking lot icons Ip1 to Ip5, and the restaurant icons Ir1 to Ir3 on the icon layer by the function of the map display unit 21c. In the present embodiment, since the bank is not a user setting type, the icon Ib1 is not drawn on the map display unit 21c.

By the function of the display control unit 21d within the attention range, the control unit 20 deletes the restaurant icons Ir1 and Ir2 and the parking lot icon Ip3, which are not the landmark facilities within the attention range, from the icon layer, and the convenience store of KK, which is a landmark facility. Icon Ic1 is redrawn in a more emphasized manner than usual.

As a result, as shown in FIG. 3D, the convenience store icon Ic1 of KK, which is a landmark facility, is highlighted around the current position icon I1, but the restaurant icons Ir1 and Ir2 and the parking lot icon Ip3 are not displayed. It becomes. Therefore, the icon Ic1 which is a landmark facility can be made to stand out, and the possibility that the user can easily recognize the convenience store of KK as a landmark facility can be increased. The convenience store (Ic1) of KK, which is a landmark facility, is displayed in a normal manner while it is located outside the attention range (see FIG. 3B), and is highlighted when it is within the attention range, and attention is paid again. If it is out of the range, it will be displayed in the normal manner. Since the AA bank (Ib1) is out of the range of attention and is not a user setting type, it is not displayed on the touch panel display 42 as shown in FIG. 3D.

FIG. 4A shows a state in which the user has progressed further on the route than the state of FIG. 3C. In the state of FIG. 4A, there are a convenience store (Ic1) of KK, a parking lot (Ip3, Ip4, Ip5), and an AA bank (Ib1) within the range of attention. Further, outside the range of attention, there are restaurants (Ir1, Ir2, Ir3, Ir4), parking lots (Ip2, Ip6), and JJ convenience stores (Ic2).

By the function of the map display unit 21c, the control unit 20 has an icon Ic1 indicating a convenience store of KK, which is a user setting type, an icon Ic2 indicating a convenience store of JJ, a parking lot icon Ip2 to Ip6, and a restaurant. The icons Ir1 to Ir4 are drawn on the icon layer. In the present embodiment, since the bank is not a user setting type, the icon Ib1 is not drawn on the map display unit 21c.

By the function of the display control unit 21d within the attention range, the control unit 20 erases the parking lot icons Ip3, Ip4, and Ip5 that are not the landmark facilities within the attention range from the icon layer, and deletes the convenience store icon Ic1 of KK, which is the landmark facility. The drawing is redrawn in a mode emphasized more than usual, and the AA bank icon Ib1 is newly drawn in a mode emphasized more than usual.

As a result, as shown in FIG. 3D, the convenience store icon Ic1 and the AA bank icon Ib1 of KK, which are landmark facilities, are highlighted around the current position icon I1, but the parking lot icons Ip3, Ip4, and Ip5 are highlighted. It will be hidden. Therefore, the icon Ic1 and the icon Ib1 which are the landmark facilities can be made to stand out, and the possibility that the user can easily recognize the convenience store of KK and the AA bank as the landmark facility can be increased. The landmark facility, AA Bank (Ib1), is not displayed while it is located outside the attention range (see FIGS. 3B and 3D), is highlighted when it enters the attention range, and is out of the attention range again. Then it will be hidden.

(2) Map drawing process:
Next, the map drawing process executed by the control unit 20 will be described with reference to FIG. In the present embodiment, the map drawing process is a process that is repeatedly executed at regular time intervals when a route guidance start instruction is received after the route search to the destination. When the map drawing process is started, the control unit 20 draws a map including the facility of the user setting type (step S100). That is, the control unit 20 acquires the current position of the smartphone 10 based on the output signal of the positioning sensor 41, and sets the default range including the current position as the map display target range. The control unit 20 draws a background image corresponding to the terrain in the display target range on the background layer based on the terrain data. The control unit 20 draws an image of the road on the road layer based on the node data indicating the intersections and roads included in the display target range, the link data, and the shape interpolation point data. The control unit 20 draws an image showing the route to the destination on the route layer. The control unit 20 draws the current position icon on the icon layer.

The control unit 20 acquires the facility data of the facility included in the display target range with reference to the map information 30a. The control unit 20 determines whether or not the type is the user setting type for each facility located within the display target range by the function of the user setting type acquisition unit 21a. The control unit 20 draws an icon indicating a facility of the user setting type within the display target range at the position of the facility in the icon layer in a normal display mode by the function of the map display unit 21c.

Subsequently, the control unit 20 executes the processes from steps S105 to S125 for each facility (facility of user setting type, mark facility) located within the display target range. In step S105, the control unit 20 determines whether or not the facility is within the attention range by the function of the attention range display control unit 21d. Specifically, the control unit 20 specifies a range (entire circumference range) equal to or less than a predetermined distance centered on the current position as a attention range. Then, the control unit 20 selects one facility (facility of the user setting type, mark facility) located within the display target range and has not executed the processing from step S105 as the processing target, and the facility pays attention to the facility. Determine if the facility is within range.

When it is determined in step S105 that the facility is within the attention range, the control unit 20 determines whether or not the facility to be processed is a landmark facility by the function of the attention range display control unit 21d (step S110). ). That is, the control unit 20 refers to the mark facility information 30c and determines whether or not the facility to be processed corresponds to the mark facility.

If it is not determined in step S110 that the facility is a landmark facility, the control unit 20 hides the facility to be processed by the function of the attention range display control unit 21d (step S115). That is, the facility to be processed drawn in step S100 is deleted from the icon layer.

If it is not determined in step S110 that the facility is a mark facility, the control unit 20 draws the facility to be processed in an emphasized mode by the function of the display control unit 21d within the attention range (step S120). That is, the control unit 20 temporarily erases the facility to be processed drawn in step S100, and draws (replaces) the facility to be processed on the icon layer in a manner emphasized more than usual.

If it is not determined in step S105 that the facility is within the attention range, the control unit 20 determines whether or not all the facilities have been processed by the function of the attention range display control unit 21d, and the processing has been completed. If not, the process returns to step S105. If the processing has been completed, the control unit 20 ends the map drawing process. When the map drawing process is completed, the control unit 20 displays the map on the touch panel display 42 based on the drawing data of each layer.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, and various other embodiments can be adopted. For example, the navigation system may be a device mounted on a vehicle or the like, a device realized by a portable terminal, or a device realized by a plurality of devices (for example, a client and a server). It may be a device. Further, at least a part of the user setting type acquisition unit 21a, the mark facility acquisition unit 21b, and the map display unit 21c constituting the navigation system may be divided into a plurality of devices and exist. For example, the navigation system may be configured to acquire a map drawing result or the like by making a request to the server via communication, and the navigation system may display the map based on the drawing result. Of course, some configurations of the above-described embodiments may be omitted, and the order of processing may be changed or omitted.

The map display unit may display a map including facilities of the user setting type on the display unit. The map may or may not include the current location of the navigation system. When the current position is not included, for example, a guide intersection on the guide route may be included. That is, the map may include a range that can be a range of interest. The map is not limited to the one displayed during the route guidance to the destination, and may be displayed when the route guidance to the destination is not performed. The facility of the user setting type may be displayed by an icon corresponding to the facility type, an icon such as a company logo, or may be displayed by a character string of the facility name.

The display control unit within the attention range may hide the facility of the user setting type and display the mark facility in the attention range of the map. The range of interest of the map may include various aspects as long as it is within the range that the user is expected to pay attention to. For example, the area of interest of the map may be a range centered on the landmark facility or a range centered on a point between the landmark facility and the current position of the navigation system. Further, the attention range of the map may be a range centered on a point designated by the user on the map.

Further, in the range of interest, the landmark facility may be displayed in a normal manner or may be highlighted. The highlighting may be a blinking display of an icon or a facility name character, or may be a display of a graphic in a color that easily attracts the user's attention in the vicinity of a company logo or the like. The landmark facility may be displayed by an icon corresponding to the facility type, an icon such as a company logo, or may be displayed by a character string of the facility name.

In the above embodiment, an example of navigation for pedestrians has been described, but it is of course applicable to navigation for vehicles. In the case of vehicle navigation, the link data of the roadway in the map information 30a is referred to. A configuration may be adopted in which different attention ranges are applied between the pedestrian navigation and the vehicle navigation. In the case of multimodal route guidance, the mode of the attention range may be switched between the walking section and the vehicle driving section. For example, since the average moving speed of the vehicle is faster than that of the pedestrian, the size of the attention range may be larger than that of the pedestrian navigation, or the shape may be longer toward the front side in the traveling direction.

Further, in the case of pedestrian navigation, the attention range is the entire circumference range of the current position, and in the case of vehicle navigation, the attention range may be a range in front of the current position. In the case of pedestrian navigation, it may be considered that the user may turn his / her line of sight not only to the front side in the traveling direction but also to the rear side while walking, and the entire circumference range of the current position may be set as the attention range. In the case of vehicle navigation, it is considered unlikely that the line of sight is directed to the rear side in the traveling direction, and the range of attention may be the range in front of the current position as shown in FIG. 6A, for example.

Further, in the case of pedestrian navigation, the attention range may be a range including the current position, and in the case of vehicle navigation, the attention range may be a range including a guide intersection. The guide intersection may be assumed to be a right / left turn intersection on the guide route (example: FIG. 6B). According to this configuration, the user can easily grasp the current position and the traveling direction by the landmark facility while walking, and can easily grasp the next guide intersection by the marker facility while driving the vehicle.

If there is no landmark facility in the attention range, a configuration in which the attention range is expanded may be adopted. If there is no landmark facility in the attention range, no facility other than the landmark facility is displayed in the attention range. Therefore, by expanding the attention range so that at least one landmark facility is included in the attention range, it is possible to increase the possibility that the user can easily grasp the landmark facility. In addition, if there is no landmark facility in the attention facility, the attention range is expanded to the upper limit, and if the landmark facility does not exist in the attention range after expansion even after the expansion, the user is within the attention range. The facility of the setting type may be displayed. By doing so, the user can recognize the current position, the guide intersection, etc. based on the facility of the user setting type.

When there are no two or more landmark facilities in the attention range, a configuration in which the attention range is expanded may be adopted. Even if there is only one landmark facility within the range of attention, it is more difficult to grasp the current position and the direction of travel than when there are multiple landmark facilities. Therefore, by expanding the range of attention until a plurality of landmark facilities are included, it is possible to make it easier for the user to recognize the current position, the traveling direction, and the like depending on the positional relationship of the plurality of landmark facilities.

In addition, when the attention range includes the current position, it is determined whether or not the marker facility exists for each range of the two divisions of the attention range along the line along the road where the current position exists, and the range where the marker facility does not exist. You may adopt the configuration which extends. For example, as shown in FIG. 7A, the area of interest indicated by the broken line circle is divided into two semicircles on the left and right sides of the traveling road, and the range on the left side in the traveling direction includes a gas station (Ig), which is a landmark facility. , The range on the right does not include landmark facilities. Therefore, the semicircle, which is the range on the right side, is expanded by the default amount. As shown in FIG. 7B, the convenience store (Ic1), which is a landmark facility, is included in the expanded range. Therefore, in this case, the range on the left side remains in the initial state and only the range on the right side is expanded. Then, as shown in FIG. 7C, in the range of the size of the initial state on the left side, the mark facility (Ig) located within the range is highlighted, and other facilities of the user setting type are hidden. Further, in the expanded range on the right side, the landmark facility (Ic1) is highlighted in the range, and other facilities of the user setting type are hidden. By doing so, it is possible to increase the possibility that one landmark facility can be displayed on each of the left and right sides based on the road whose current position matches.

Such a configuration that allows at least one mark facility to be displayed on each of the left and right sides is also useful in the following cases. For example, as shown in Fig. 7D, if sidewalks are provided on both sides of a wide roadway and the user is walking on one of the sidewalks on the right side, the right side of the sidewalk is the facility next to the sidewalk. However, the left side of the sidewalk is the area where the facility exists across the wide road. In such a case, by expanding the range obtained by dividing the predetermined range into two on the roadway side, it is possible to increase the possibility that at least one mark facility can be displayed on each of the left and right sides.

Further, as in the present invention, there is a method of displaying a map including facilities of a user setting type on a display unit, hiding the facilities of the user setting type in the attention range of the map, and displaying the landmark facilities. , Can also be applied as a program or method. In addition, the above systems, programs, and methods may be realized as a single device or may be realized by using parts shared with each part provided in the vehicle, including various aspects. It is a program. In addition, some of them are software and some of them are hardware, so they can be changed as appropriate. Further, the invention is also established as a recording medium for a program that controls a system. Of course, the recording medium of the program may be a magnetic recording medium or a semiconductor memory, and any recording medium developed in the future can be considered in exactly the same way.
