A mode for carrying out the present invention will be described with reference to FIG.

As shown in FIG. 1, the display control device 1 includes a sorting means 111A and a display control means 111B, and is connected to the display unit 2.

The sorting means 111A sorts a plurality of points into groups based on their respective positions.

The display control means 111B causes the display unit 2 to display guidance information representing a group including a point as a guidance target. A group does not necessarily have to include a plurality of points, and a group containing only one point is also called a group. As a result, since the guidance information is displayed with a plurality of points as one guidance target, the user can grasp the guidance target in a short time.

The display control means 111B displays information representing at least one point included in the group as at least a part of the guidance information. The information representing the point is, for example, a name representing the point (facility name, etc.), an administrative notation representing the point (for example, 1-1-1 XX town, XX city, XX prefecture), an icon representing the point, and the like. As a result, information representing at least one point is displayed as the guidance information, so that the user can infer other points included in the group (guidance target).

The display control device 1 may further include a current position acquisition unit 111C that acquires information indicating the current position of the display control device 1. The information indicating the current position is, for example, information indicating latitude and longitude.

Then, the display control means 111B may display the guidance information with reference to the current position based on the positional relationship between the current position and the guidance target. For example, when the display control means 111B displays the information indicating the current position and the guidance information, when the position of the group (guidance target) is northeast of the current position, the display control means 111B shifts from the information indicating the current position to the northeast position. Display a map that displays guidance information. As a result, the user can grasp at a glance which direction the group (guidance target) is in.

Further, the sorting means 111A may sort a plurality of points into groups according to the distance from the current position or the travel time. The distance may be a straight line distance or a moving distance. For example, it may be grouped into a point less than 5 km from the current position and a point 5 km or more, or it may be grouped into a point having a travel time of less than 15 minutes from the current position and a point having a travel time of 15 minutes or more. good.

Further, the display control means 111B displays information representing at least one of the points included in the group, the point farthest from the current position or the point closest to the current position, as at least a part of the guidance information. May be good. As a result, the user can roughly grasp the geographical range of the group (guidance target).

The display control device 1 may further include selection means 111D for selecting a destination candidate point according to historical information about the point. The history information about the point is, for example, information indicating the history of the user searching for the point, information indicating the history of the user visiting / passing through the point, and the like.

Then, the sorting means 111A may sort the destination candidate points selected by the selecting means 111D into groups. As a result, it is possible to display a destination candidate point that is likely to be the destination by the user.

Further, the display control means 111B displays, based on the history information, information representing the most recently visited or searched destination candidate points among the destination candidate points included in the group as at least a part of the guidance information. May be good. As a result, the user can roughly grasp the position of the group (guidance target).

Further, the selection means 111D calculates an evaluation value for a point based on the history information, selects a point where the evaluation value satisfies a predetermined criterion as a destination candidate point, and the display control means 111B is a point included in the group. Among them, the information representing the point having the highest evaluation value is displayed as at least a part of the guidance information.

The display control device 1 may further include a branch point acquisition unit 111E that acquires information indicating the position of the branch point in the traveling direction of the display control device 1.

Then, the sorting means 111A may divide the plurality of points into groups according to which direction the plurality of points are located from the branch point. As a result, even if there are a plurality of points located in any direction from the branch point, the guidance information is displayed as one guidance target, so that the user can grasp these points in a short time. can.

The display control means 111B displays guidance information only for a group including a number of points equal to or larger than the threshold value, and the threshold value is set by the size of the display unit 2, the character size of the characters displayed on the display unit 2, or the user. It may be set based on at least one of the values. For example, when the size of the display unit 2 (screen) is small or the character size is large, it is difficult to display information representing a plurality of points at the same time. Therefore, by setting a small threshold value, a plurality of points can be displayed. Instead of displaying at the same time, the guidance information can be displayed as one guidance target, which makes it easier for the user to see.

The sorting means 111A sorts a plurality of points into groups based on their respective positions, and the group including the points is further divided into subdivided groups according to a predetermined criterion, and the display control means 111B guides the groups. The guidance information represented as a target may include at least information representing a point included in each subdivision group to display the guidance information.

Next, a specific embodiment corresponding to the above-described embodiment will be described.

Examples will be described with reference to FIGS. 2- and 6. The examples described below are examples in which the present invention is applied to a navigation device mounted on a vehicle.

[1. Overview of navigation device]
First, the outline of the destination presentation function of the navigation device in this embodiment will be described. The destination presentation function estimates destination candidate points from points that have been visited or searched in the past when the user is traveling without setting a destination, and displays them on the direction signboard on the screen. It is a function to do.

The navigation device records historical information indicating a destination search history, a visit (via) history, etc. on a daily basis (whether or not the destination presentation function is activated) for the destination presentation function.

The navigation device calculates a score (an example of an "evaluation value") for estimating a user's destination candidate point as shown in FIG. 2 based on historical information by a conventionally known method. If there are many points for which the score is calculated, the point where the distance or travel time is out of the specified range from the current position of the vehicle (navigation device), or the point where a predetermined period or more has passed from the date of search / visit (via). The score may be calculated by excluding. FIG. 2 shows an example in which scores are calculated for a total of nine points, point A and point I.

FIG. 3 is a diagram showing the positional relationship of the points where the score is calculated, and the position of the vehicle is represented by the vehicle mark C. The navigation device selects a point having a score of 15 points or more (an example of "a point satisfying a predetermined criterion") as a destination candidate point. That is, in the example of FIG. 2, the point A-point G is selected as the destination candidate point, and the points H and I are not selected.

The navigation device divides (groups) the candidate destination points of points A-point G into groups according to the positions of the points. Specifically, information indicating the position of the branch point F1 in the traveling direction of the vehicle (navigation device) is acquired, and the destination candidate points are divided into groups according to which direction the vehicle (navigation device) is located in. In the example of FIG. 3, the points A and B located in the direction of turning left at the branch point F1 are grouped into the group G1. Similarly, the points C-point G located in the direction of turning right at the branch point F1 are grouped into the group G2. It should be noted that the points H and I located in the direction straight ahead of the branch point F1 are not subject to grouping because the score is less than 15 points and they are not destination candidate points.

The navigation device determines whether or not the number of destination candidate points included in the group is 3 (an example of "threshold value") or more for the groups G1 and G2. For group G1 in which the number of destination candidate points included in the group is not 3 or more, as shown in FIG. 4, a direction sign screen 500 that displays the name of the destination candidate point as it is is displayed. On the other hand, for the group G2 in which the number of destination candidate points included in the group is 3 or more, the direction signboard screen 500 that displays the guidance information (“point C / point G direction”) indicating the group as the guidance target is displayed. .. At this time, the navigation device displays guidance information including the names of the point C, which is the closest point from the current position, and the point G, which is the farthest point, among the destination candidate points included in the group G2.

As a result, the user can grasp the direction of the destination candidate point from the current position even when traveling without setting the destination. Further, not all of the destination candidate points included in the group G2 are displayed, and the guidance information indicating the group G2 as the guidance target is displayed, so that the user can grasp the guidance target in a short time. be able to.

[3. Operation example of navigation device NV]
Next, an operation example during the operation of the destination presentation function of the navigation device NV will be described with reference to the flowchart of FIG.

First, the control unit 211 of the navigation device NV calculates the score of the point based on the history information recorded in the storage device 212 (step S11). The control unit 211 may calculate the score by narrowing down to the current position of the vehicle and the points in the traveling direction of the vehicle. Further, as a method for calculating the score, a conventionally known method can be adopted.

Next, the control unit 211 selects a point having a score of 15 points or more as a destination candidate point (step S12). Although not shown, if there is no point with a score of 15 points or more, the flowchart ends.

Next, the control unit 211 identifies the branch point information recorded in the storage device 212, the current position of the vehicle, and the branch point to be reached next from the traveling direction of the vehicle (step S13).

Next, the control unit 211 groups the destination candidate points selected in the process of step S12 based on the branch point specified in the process of step S13 (step S14). At this time, the control unit 211 groups the destination candidate points for each branching direction at the branching point.

Next, the control unit 211 selects one group from the groups grouped in the process of step S14 (step S15).

Next, the control unit 211 determines whether or not the group selected in the process of step S15 includes points of 3 (an example of “threshold value”) or more (step S16). At this time, if the control unit 211 determines that it includes three or more points (step S16: YES), the control unit 211 is selected from the current position of the vehicle among the destination candidate points included in the group selected in the process of step S15. The display mode based on the guidance information including the names of the nearest point and the farthest point is determined (step S17). On the other hand, when it is determined that the control unit 211 does not include three or more points (step S16: NO), the control unit 211 determines a display mode in which the destination candidate points included in the group selected in the process of step S15 are displayed as they are. (Step S18).

Next, the control unit 211 determines whether or not there is a group not selected in the process of step S15 among the groups grouped in the process of step S14 (step S19). At this time, if the control unit 211 determines that there is a group that has not been selected (step S19: YES), the control unit 211 shifts to the process of step S15. On the other hand, when the control unit 211 determines that there is no unselected group (step S19: NO), the control unit 211 then displays the point and the group in the display mode determined in the process of step S17 or step S18. The screen 500 is displayed, and the process shown in the flowchart is terminated. That is, for the group whose display mode is determined in the process of step S17, guidance information including the closest point and the farthest point from the current position of the vehicle is displayed (for example, "point C / point G direction" in FIG. 4). For the group whose display mode is determined in the process of step S18, the names of the points included in the group are displayed as they are (for example, "point A" and "point B" in FIG. 4). (An example of "display unit") is displayed.

As described above, according to the navigation device NV according to the present embodiment, the control unit 211 (an example of the “sorting means” and the “display control means”) is a plurality of destination candidate points (an example of the “point”). Is divided into groups based on each position, and guidance information representing the group including the destination candidate point as a guidance target is displayed on the screen of the display 214c (an example of the "display unit"). As a result, the guidance information is displayed with a plurality of destination candidate points as one guidance target, so that the user can grasp the guidance target in a short time even when the guidance target is a plurality of destination candidate points. be able to.

Further, the control unit 211 of the navigation device NV according to the present embodiment provides guidance information (“point C / point”) for information (“point C”, “point G”) representing at least one candidate destination point included in the group. Display as at least a part of "G direction"). This allows the user to infer other potential destinations included in the group.

Further, the control unit 211 (an example of the "current position acquisition means") of the navigation device NV according to the present embodiment acquires the information indicating the current position and determines the current position based on the positional relationship between the current position and the guidance target. Display guidance information as a reference. As a result, the user can grasp at a glance which direction the group (guidance target) is in.

Furthermore, the control unit 211 of the navigation device NV according to the present embodiment is a name representing the destination candidate point farthest from the current position and the destination candidate point closest to the current position among the destination candidate points included in the group. Is displayed as at least a part of the guidance information. As a result, the user can roughly grasp the geographical range of the group (guidance target). Information representing at least one of the destination candidate points farthest from the current position or the destination candidate point closest to the current position may be displayed as at least a part of the guidance information.

Furthermore, the control unit 211 (an example of the "selection means") of the navigation device NV according to the present embodiment selects a destination candidate point according to the history information about the point, and sorts the destination candidate points as the points into groups. .. As a result, it is possible to display a destination candidate point that is likely to be the destination by the user.

Furthermore, the control unit 211 (an example of the "branch point acquisition means 111E") of the navigation device NV according to the present embodiment acquires information indicating the position of the branch point in the traveling direction of the vehicle (navigation device NV). Multiple destination candidate points are classified into groups according to the direction from the branch point. As a result, when there are three or more destination candidate points located in any direction from the branch point, the guidance information is displayed as one guidance target, so that the user can grasp these destination candidate points in a short time. can do.

In this embodiment, the case where the present invention is applied to the in-vehicle navigation device NV has been described, but it is applied to a portable navigation device, a smartphone, a tablet terminal, a PC, etc. on which a navigation application program is installed. You can also do it.

[4. Modification example]
Next, a modified example of the above embodiment will be described. The modifications described below can be combined as appropriate.

[4.1. Modification 1]
In the above embodiment, the control unit 211 has decided to display the guidance information including the names of the points closest to the current position and the points farthest from the current position for the group including three or more candidate destination points. Or, in addition, after selecting a point with a score of 15 points or more as a destination candidate point, as shown in FIG. 7, information indicating the point having the highest score (see FIG. 2) among the points included in the group (see FIG. 2). For example, the name) may be displayed as at least a part of the guidance information.

Further, as shown in FIG. 2, the number of days elapsed since the user visited (via) or searched for each point is stored in the storage device 212, and the control unit 211 stores the number of days elapsed since the user visited (via) or searched, as shown in FIG. Among the destination candidate points included in the group, information (for example, a name) representing the most recently visited or searched destination candidate point (see FIG. 2) may be displayed as at least a part of the guidance information. As a result, the user can roughly grasp the position of the group (guidance target).

[4.2. Modification 2]
In the above embodiment, in the process of step S14, the control unit 211 groups the destination candidate points for each branching direction at the branch point, but instead, the control unit 211 has a plurality of destination candidates. The points may be divided into groups according to the distance from the current position or the travel time from the current position. For example, as shown in FIG. 9, when the vehicle represented by the vehicle mark C moves on a straight road, if 5 km is set as the threshold value indicating the boundary B1, the destination candidate point less than 5 km from the current position. Group G3 including point R and point Q, and group G4 including point S, point T, and point U, which are candidate points for destinations of 5 km or more, are divided into groups, and 15 minutes is set as a threshold value representing boundary B1. If so, the group G3 including the destination candidate points R and the point Q whose travel time is less than 15 minutes from the current position, and the point S, the point T, and the point U which are the destination candidate points of 15 minutes or more. The group is divided into groups G4 including. Then, as shown in FIG. 10, the control unit 211 displays the information representing the points as it is for the group G3 (the group not including the points of 3 or more), and for the group G4 (the group including the points of 3 or more). , Guidance information including information representing any of the points included in group G4 (eg, the point with the highest score, the point closest to the current position, the point farthest from the current position, the point most recently visited or searched). Display it. As a result, even if there are multiple candidate destination points in the same direction of travel, information on both points near and far from the current position is displayed on the direction signboard, so only one of them is displayed. Can be avoided. In this modified example, in the process of step S14 of FIG. 6, as a result of grouping the destination candidate points for each branching direction at the branching point, only one direction group can be formed (for example, all groups). It can be applied to (when the destination candidate point is located in the straight line direction).

Further, as shown in FIG. 11, the control unit 211 has a target in the direction of turning left at the branch point F2, a group G5 including the points K and J which are candidate destination points in the direction of turning left at the branch point F2, and a target in the direction of turning right at the branch point F2. Grouping is performed with group G6 including point L, point M, point N, point O, and point P, which are candidate sites, and as a result, the maximum distance between points included in the same group (the point closest to the current position). And the distance of the farthest point from the current position) ”is equal to or greater than the threshold value (for example, 20 km), the group may be further divided to form a subdivided group. For example, in the example of FIG. 11, when the distance between the point L and the point P included in the group G6 is 20 km or more and the group G6 is further subdivided, the control unit 211 sets the branch point F2 as a threshold value indicating the boundary B2. If 5 km is set (the distance from the current position may be set), the group G7 (“subdivision group”” including the point L and the point M, which are candidate destination points less than 5 km from the branch point F2. (Example)) and group G8 (an example of a "subdivision group") including point N, point O, and point P, which are candidate destination points of 5 km or more. Then, as shown in FIG. 12, the control unit 211 displays the information representing the points as it is for the group G5 (group not including 3 or more points), and for the group G6 (group including 3 or more points). , Any of the points included in the further subdivided group 7 (for example, the point with the highest score, the point closest to the current position, the point farthest from the current position, the point most recently visited or searched). Information that represents and information that represents any of the points included in Group 8 (for example, the point with the highest score, the point closest to the current position, the point farthest from the current position, the point most recently visited or searched). Display guidance information including at least. As a result, even if there are multiple destination candidate points in the same direction of travel after turning right at the branch point F2, information on both points near and far from the current position will be displayed on the direction signboard. It is possible to avoid displaying only one of them.

[4.4. Modification 4]
In the above embodiment, the control unit 211 displays the guidance information only for the group including the number of destination candidate points of 3 or more, which is the threshold value in the process of step S16 of FIG. 6, but the threshold value is 2. On condition that the above conditions are met, the setting may be made based on at least one of the size of the display unit 2 (screen), the character size of the characters displayed on the display unit 2, or the value set by the user. .. For example, when the size of the display unit 2 (screen) is small or the character size is large, it is difficult for the control unit 211 to simultaneously display information representing a plurality of points, so that the threshold value may be set small. Alternatively, the value may be set so that the user can easily see it. This improves the visibility of the user.

[4.5. Modification 5]
In the above embodiment, the guidance information including at least the point name is displayed as the information indicating the point, but instead of or in addition to this, the genre to which the point belongs (restaurant, convenience store, parking lot, etc.) ), Or an icon indicating a logo or mark indicating a specific chain store or the like may be displayed.

[4.6. Modification 6]
As shown in FIG. 3, when the branch point F1 is turned right and a branch point F3 exists further ahead, as shown in FIG. 13, whether to proceed the branch point F3 to the left or to the right. Group G2 is further grouped accordingly, and any of the points included in each group (eg, the point with the highest score, the point closest to the current position, the point farthest from the current position, the most recent visit or search).
