It is a figure which shows the display example of a direction signboard.

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 calculation means 111A, an aggregation means 111B, and a display control means 111C, and is connected to the display unit 2.

The calculation means 111A calculates an evaluation value for the point based on the history 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. The evaluation value is, for example, a numerical value indicating the degree of possibility that the user will be the destination, and the higher the numerical value, the higher the possibility that the user is the destination.

The aggregation means 111B aggregates the evaluation values and calculates the aggregation evaluation value for the area to which the point where the evaluation value is calculated belongs among the preset areas. The preset area is, for example, an administrative division (city, ward, town, village, etc.), but can be arbitrarily set.

The display control means 111C causes the display unit 2 to display information regarding a special area in which the aggregated evaluation value satisfies the first criterion. The first criterion is, for example, a preset threshold value for comparison with the aggregated evaluation value.

Therefore, according to the display control device 1, it is possible to display information about a special area that is likely to include the user's destination.

The display control device 1 may further include a current position acquisition unit 111D 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 111C may display the information regarding the special area differently depending on whether the current position is inside the special area or outside the special area. As a result, the user can grasp at a glance whether or not the current position is in a special area that is likely to include the destination.

Further, when the current position is in the special area, the display control means 111C may display information indicating a point belonging to the special area. 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, when the current position is in a special area that is likely to include the destination, the user can grasp the point belonging to the special area at a glance.

Further, the display control means 111C may display the guidance information representing the special area as the guidance target when the current position is outside the special area. This makes it easier for the user to move in the direction of a special area that is likely to contain the destination.

Furthermore, the display control means 111C may display more information about the special area than the information about the area where the aggregated evaluation value does not satisfy the first criterion. As a result, more information about the special area that is likely to be the destination is displayed than information about the area that is unlikely to be the destination, so that the user obtains a lot of information that is likely to be useful. can do. In order to display more information about the special area than the information about the area where the aggregated evaluation value does not meet the first criterion, the information about the special area is displayed to some extent and the aggregated evaluation value does not satisfy the first criterion. Includes not displaying any information about the area.

In addition, the upper area including a plurality of the said areas may be set in advance. For example, when an area identified by a city / ward / town / village name is set (for example, Kawagoe City), an area identified by a prefecture name (for example, Saitama Prefecture) can be set as a higher-level area. Then, when there is no area where the aggregated evaluation value satisfies the first criterion, the aggregation means 111A aggregates the evaluation values and aggregates the upper area to which each point for which the evaluation value is calculated belongs. The evaluation value is calculated, and the display control means 111C displays guidance information indicating the special upper area as a guidance target when the current position is not included in the special upper area where the upper total evaluation value satisfies the second criterion. You may let it. The second criterion is, for example, a preset threshold value for comparison with the top aggregate evaluation value. This makes it easier for the user to move in the direction of the special higher area that is likely to include the destination.

Furthermore, when the current position is outside the special area to which the special point whose evaluation value satisfies the third criterion belongs, the display control means 111C provides the information indicating the special point together with the guidance information indicating the special area as the guidance target. It may be displayed. The third criterion is, for example, a preset threshold value for comparison with the evaluation value. As a result, not only the guidance information indicating the special area as the guidance target but also the information indicating the point having a high possibility of the destination is displayed, so that the user can easily grasp what kind of area the special area is.

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

Examples will be described with reference to FIGS. 2-FIG. 8. 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 the destination candidate point or the area including the destination candidate point from the points that the user has visited or searched in the past when traveling without setting the destination. It is a function to be displayed on the direction signboard on the screen.

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. The higher the score value, the more likely it is the user's destination. Therefore, it is possible to present the points whose score is above a certain level to the user as destination candidate points. If there are many points for which the score is calculated, the point where the distance or travel time is outside 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 were calculated for a total of five points: "company", "convenience store", and "gas station" in Kawagoe City, and "supermarket" and "nursery school" in Fujimino City.

The navigation device calculates an area score for each area to which the point belongs. The area score is the sum of the scores of the points belonging to the area. If the score calculated for a point is less than a certain value, it is unlikely that the point is a candidate destination for the user, so it is desirable not to present it to the user. Instead, the navigation device presents the area to the user as the area to which the destination candidate point belongs if the area score is above a certain level. In the example of FIG. 2, the area score is calculated for the Kawagoe city area and the Fujimino city area. In this embodiment, the navigation device displays information about an area having an area score of 50 or more (an example of the "first criterion") on the direction signboard.

FIG. 3 is a diagram showing the positional relationship of points belonging to the Kawagoe City area having an area score of 50 or more, and the position of the vehicle is represented by the vehicle mark C. In the example of FIG. 3, the vehicle is located outside the Kawagoe city area. In this case, as shown in FIG. 4, the navigation device displays a direction signboard 500 indicating that the straight direction is toward Kawagoe City. On the other hand, in the example of FIG. 5, the vehicle is located in the Kawagoe city area. In this case, as shown in FIG. 6, the navigation device displays the names “company”, “convenience store”, and “gas station” of the points belonging to the Kawagoe city area on the direction signboard 500 in association with the direction of the points. Specifically, as shown in FIG. 5, the "company" is located in the direction of going straight through the branch point F1, the "convenience store" is located in the direction of turning right at the branch point F1, and the "gas station" is located in the direction of turning right at the branch point F1. Since it is located in the direction of turning left, the direction sign 500 also has information indicating "company" in the straight direction, information indicating "convenience store" in the right turn direction, and information indicating "gas station" in the left turn direction. indicate. That is, for the Kawagoe city area where the area score is 50 or more, when the current position is outside the Kawagoe city area, the navigation device displays the guidance information for the Kawagoe city area as the guidance target, while the current position is Kawagoe. If it is within the city area, the guidance information is displayed for the points belonging to the Kawagoe city area.

According to this embodiment, even if the score is low as an individual point and it cannot be presented to the user as a destination candidate point, an area having a certain score is given to the user as an area including the destination candidate point. Can be presented. In addition, the user will not be confused by not presenting the area that does not have a certain score.

The map information includes information that can determine which area (city, ward, town, village, prefecture) the point to which the navigation device NV can guide belongs.

Further, the storage device 212 stores information necessary for realizing the destination presentation function. For example, it stores history information indicating a user's destination search history, point visit history (via history), and branch point information (information indicating the position of a branch point) related to a branch point.

The input device 213 is composed of a touch panel, a keyboard, a mouse, another controller, and the like, receives an input operation of the user, and transmits an operation signal indicating the operation content to the control unit 211.

Control each movement of the member.

[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 totals the scores of the points for each area and calculates the area score (step S12).

Next, the control unit 211 determines whether or not there is an area in which the area score is equal to or higher than the threshold value (“50” in this embodiment) among the area scores calculated in the process of step S12 (step S13). At this time, if the control unit 211 determines that there is no area whose area score is equal to or higher than the threshold value (step S13: NO), the control unit 211 ends the process shown in the flowchart. On the other hand, when the control unit 211 determines that there is an area whose area score is equal to or higher than the threshold value (step S13: YES), the control unit 211 determines the area as a display area (an example of a "special area") (step S14).

Next, the control unit 211 determines whether or not there is a display area including the current position among the display areas determined in the process of step S13 (step S15). At this time, when the control unit 211 determines that there is a display area including the current position (step S15: YES), the control unit 211 displays the direction signboard screen 500 displaying the name of each point belonging to the display area on the display 214c. (Step S16), and the process shown in the flowchart is terminated. On the other hand, when the control unit 211 determines that there is no display area including the current position (step S15: NO), the control unit 211 displays the direction sign screen 500 displaying the name of the display area determined in the process of step S14 on the display 214c. It is displayed (step S17), and the process shown in the flowchart is terminated.

As described above, according to the navigation device NV (an example of the "display control device 1") according to the present embodiment, the control unit 211 (an example of the "calculation means", the "aggregation means", and the "display control means"). Calculates the score (an example of "evaluation value") for the point based on the history information about the point, and totals the score for the area to which the point for which the score is calculated belongs among the areas set in advance by the administrative divisions. Calculates the area score (an example of "aggregated evaluation value") and displays information about the Kawagoe city area, which is an area with an area score of 50 or more (an example of "area that meets the first criterion" and "special area"). It is displayed on the screen of 214c (an example of "display unit 2").

Therefore, according to the navigation device NV according to the present embodiment, it is possible to display information about the Kawagoe city area that is likely to include the user's destination.

Further, the control unit 211 (an example of the "current position acquisition means") of the navigation device NV according to this embodiment acquires information indicating the current position of the navigation device NV, and the current position is in the Kawagoe City area. The display mode of information about the Kawagoe City area differs depending on whether it is outside the Kawagoe City area. As a result, the user can grasp at a glance whether or not the current position is within the Kawagoe City area, which is likely to include the destination.

Further, when the current position is within the Kawagoe City area, the control unit 211 of the navigation device NV according to the present embodiment names the points "company", "convenience store", and "gas station" belonging to the Kawagoe City area. Display it. As a result, the user can grasp at a glance the points belonging to the Kawagoe city area when the current position is within the Kawagoe city area which is likely to include the destination.

Furthermore, when the current position is outside the Kawagoe City area, the control unit 211 of the navigation device NV according to the present embodiment displays guidance information indicating the Kawagoe City area as a guidance target. This makes it easier for the user to move in the direction of the Kawagoe city area, which is likely to include the destination.

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 calculates the area score for the area, but in addition to this, the upper area score may be calculated for the upper area which is the upper part of the area. In the above embodiment, the area is associated with the "city" level, but in this modification, the upper area is associated with the "prefecture" level.

Figure 9 shows scores for a total of 6 points: "company", "convenience store", "gas station" in Kawagoe City, "supermarket", "nursery school" in Fujimino City, and "restaurant" in Nerima Ward. The calculated example is shown. In this example, the area score is "65" for the Kawagoe city area, "25" for the Fujimino city area, and "10" for the Nerima ward area. Here, assuming that the threshold value for determining the display area (threshold value in step S13) is set to, for example, "70", the display area is not determined.

Therefore, in this modification, the control unit 211 calculates the upper area score for the upper area of the area. In the example of FIG. 9, the high-ranking area score is "90" for the Saitama prefecture area and "10" for the Tokyo metropolitan area. Here, the upper area score of the Saitama prefecture area determines the threshold value "70" for determining the display area (the threshold value is set depending on whether the display area is determined in the area or the display area is determined in the upper area). It may be changed. It will be described as not changing in this modification.) Therefore, the control unit 211 determines the Saitama prefecture area as the display area. Then, when the current position is outside the Saitama prefecture area, the control unit 211 displays the direction signboard screen 500 indicating the direction of the Saitama prefecture area as shown in FIG.

That is, the control unit 211 of this modification is a higher-level area when there is no area (an example of the "area satisfying the first criterion") in which the area score (an example of the "aggregated evaluation value") is "50" or more. Of these, for the upper area to which each point for which the score (an example of "evaluation value") belongs, the scores are aggregated to calculate the upper area score (an example of "upper total evaluation value"), and the upper area score is " A direction to display guidance information indicating the Saitama prefecture area as a guidance target when the current position is not included in the Saitama prefecture area, which is an area of 70 "or more (an example of a" special upper area that meets the second criterion "). The signboard screen 500 is displayed. This makes it easier for the user to move in the direction of the Saitama prefecture area, which is likely to include the destination.

[4.2. Modification 2]
In this modification, when the control unit 211 determines "NO" in the process of step S15 of FIG. 8, it is a point in the display area and has a score of "40" or more ("" It is determined whether there is an example of "a point where the evaluation value satisfies the third criterion"), and if there is a corresponding point, the corresponding point is determined as a display point (an example of "special point"). Then, when the current position of the vehicle is outside the display area, the control unit 211 displays the information indicating the display point together with the guidance information indicating the display area as the guidance target.

For example, in the example of FIG. 11, the control unit 211 determines the Kawagoe city area as the display area, and the score of the "company" belonging to the Kawagoe city area is "55" ("40" or more), so that the display point is set. decide. Then, when the current position of the vehicle is outside the Kawagoe City area, the control unit 211 displays the direction signboard screen 500 indicating the direction of the "company" and the Kawagoe City area, as shown in FIG.

That is, the control unit 211 of this modification is Kawagoe City to which the "company" to which the score (an example of the "evaluation value") is "40" or more (an example of the "special point satisfying the third criterion") belongs. If the current location is outside the area (an example of "special area"), the information indicating "company" is displayed together with the guidance information indicating the Kawagoe city area as the guidance target. As a result, not only the guidance information indicating the Kawagoe city area as the guidance target but also the information indicating the "company" is displayed, so that the user can easily grasp what kind of area the Kawagoe city area is.

[4.3. Modification 3]
This modification is a modification in which the control unit 211 determines a plurality of areas as display areas. In this modification, the threshold value for determining the display area is calculated by the following equation (1).
Threshold = (1 / number of areas for which area score is calculated) x 100 (1) Equation For example, in the example of FIG. 13, "number of areas for which area score is calculated" is three areas of Kawagoe City, Fujimino City, and Tokorozawa City. Therefore, the threshold value is "33" (the processing after the decimal point may be rounded down, rounded up, rounded off, or the like). Then, the control unit 211 determines the Kawagoe city area and the Tokorozawa city area, which are areas where the area score is the threshold value “33” or more, as the display area.

FIG. 14 is a diagram showing an example of the positional relationship between the Kawagoe City area and the Tokorozawa City area, which are display areas, and the points belonging to the respective areas. That is, if you turn right at the fork F2 in the direction of travel of the vehicle, you will be in the direction of the Kawagoe City area, and the "company" and "convenience store" belong to the Kawagoe City area. On the other hand, if you go straight on the fork F2, you will be in the direction of Tokorozawa City area, and "Station" and "Restaurant" belong to Tokorozawa City area. When the positional relationship between the two display areas, the Kawagoe city area and the Tokorozawa city area, is as shown in FIG. 14, the control unit 211 represents the Tokorozawa city area as a guidance target in the straight direction as shown in FIG. In addition to displaying the guidance information, the direction signboard screen 500 for displaying the guidance information indicating the Kawagoe city area as the guidance target is displayed in the right turn direction. As a result, it is possible to present the user with a plurality of areas that are likely to include the destination.
