A mode for carrying out the present invention will be described using FIG. 1.

As shown in FIG. 1, the display control device 1 includes a calculation means 111A, a totaling means 111B, and a display control means 111C, and is connected to the display section 2.

The calculation means 111A calculates an evaluation value for the point based on historical information regarding the point. The history information regarding a point is, for example, information indicating a history of a user's search for a point, information indicating a history of a user visiting or passing through a point, and the like. The evaluation value is, for example, a numerical value representing the degree of possibility that the user will select the destination as the destination, and the higher the numerical value, the higher the possibility that the destination is the user's destination.

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

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

Therefore, the display control device 1 can display information regarding a special area that is likely to include the user's destination.

The display control device 1 may further include current position acquisition means 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.

The display control means 111C may display information regarding the special area differently depending on whether the current position is inside the special area or outside the special area. This allows the user to understand at a glance whether the current location is within a special area that is likely to include the destination.

Furthermore, when the current position is within the special area, the display control means 111C may display information representing a point belonging to the special area. The information representing the location includes, for example, a name representing the location (facility name, etc.), an administrative notation representing the location (for example, 1-1-1 XXX-cho, XXX City, XXX Prefecture), an icon representing the location, and the like. Thereby, if the user's current position is within a special area that is likely to include the destination, the user can grasp at a glance the points belonging to the special area.

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

Furthermore, the display control means 111C may display more information regarding the special area than information regarding the area whose total evaluation value does not satisfy the first criterion. This allows the user to receive more information that is likely to be useful, as more information about special areas that are likely to be a destination is displayed than information about areas that are less likely to be a destination. can do. Note that displaying more information about special areas than information about areas whose aggregated evaluation values do not satisfy the first criterion involves displaying a certain amount of information about the special areas and displaying a certain amount of information about the special areas whose aggregated evaluation values do not satisfy the first criterion. This includes not displaying any information about the area.

Note that an upper area including a plurality of the above areas may be set in advance. For example, when an area identified by a city, ward, town, or village name is set (for example, Kawagoe City), an area identified by a prefecture name (for example, Saitama Prefecture) can be set as an upper area. Then, when there is no area for which the aggregated evaluation value satisfies the first criterion, the aggregation means 111A aggregates the evaluation values for the upper area to which each point for which the evaluation value has been calculated belongs, among the upper areas, to aggregate the higher ranking. The evaluation value is calculated, and if the current position is not included in the special high-rank area where the high-rank aggregated evaluation value satisfies the second criterion, the display control means 111C displays guidance information representing the special high-rank area as a guidance target. It is also possible to do so. The second standard is, for example, a threshold value set in advance for comparison with the higher-rank aggregated evaluation value. This makes it easier for the user to move in the direction of the special high-rank area that is likely to include the destination.

Furthermore, if the current position is outside the special area to which a special point whose evaluation value satisfies the third criterion belongs, the display control means 111C displays information representing the special point along with guidance information representing the special area as a guidance target. It may also be displayed. The third standard is, for example, a threshold value set in advance for comparison with the evaluation value. This allows the user to easily understand what kind of area the special area is since not only the guidance information representing the special area as a guidance target but also information representing a point with a high possibility of a destination is displayed.

Next, specific examples corresponding to the above-described embodiments will be described.

An example will be described using FIGS. 2 to 8. The embodiments 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, an outline of the destination presentation function of the navigation device in this embodiment will be explained. The destination presentation function estimates a potential destination point or an area containing a potential destination point from among the points that the user has visited or searched for in the past when the user is driving without setting a destination. This function displays the directions on the on-screen directional signboard.

For the purpose of the destination presentation function, the navigation device routinely records history information indicating the search history, visitation (via) history, etc. of the destination (regardless of whether the destination presentation function is in operation or not).

The navigation device calculates a score (an example of an "evaluation value") for estimating a user's destination candidate point for a point, as shown in FIG. 2, using a conventionally known method based on historical information. The higher the score value, the more likely it is the user's destination. Therefore, points with scores above a certain level can be presented to the user as destination candidate points. If there are many points to calculate the score, points whose distance or travel time is outside the specified range from the current position of the vehicle (navigation device), or points where a specified period of time or more has passed since the date of search/visit (via). The score may be calculated by excluding the following. Figure 2 shows an example in which scores were calculated for a total of five locations: "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 a point belongs. The area score is the sum of scores of points belonging to the area. If the score calculated for a point is less than a certain value, that point is unlikely to be a candidate destination point for the user, so it is desirable not to present it to the user. Instead, if the area score is above a certain level, the navigation device presents the area to the user as the area to which the destination candidate point belongs. In the example of FIG. 2, area scores are calculated for the Kawagoe City area and the Fujimino City area. In this embodiment, the navigation device displays information regarding areas with an area score of 50 or higher (an example of a "first criterion") on a direction signboard.

FIG. 3 is a diagram showing the positional relationship of points belonging to the Kawagoe City area with an area score of 50 or higher, and the position of a vehicle is represented by a vehicle mark C. In the example of FIG. 3, the vehicle is located outside the Kawagoe City area. In this case, the navigation device displays a direction signboard 500 indicating that the straight direction is toward Kawagoe City, as shown in FIG. On the other hand, in the example of FIG. 5, the vehicle is located within the Kawagoe City area. In this case, the navigation device displays the names of points belonging to the Kawagoe City area, "company," "convenience store," and "gas station," in association with the directions of the points on the direction signboard 500, as shown in FIG. Specifically, as shown in Figure 5, the "company" is located in the direction that goes straight ahead from the junction F1, the "convenience store" is located in the direction that turns right at the junction F1, and the "gas station" is located in the direction that goes straight ahead at the junction F1. Therefore, in accordance with this, the direction signboard 500 also includes information indicating "company" in the direction of going straight, information indicating "convenience store" in the direction of right turn, and information indicating "gas station" in the direction of left turn. indicate. That is, for the Kawagoe City area with an area score of 50 or more, if the current location is outside the Kawagoe City area, the navigation device displays guidance information for the Kawagoe City area; If the location is within the city area, guidance information will be displayed with points belonging to the Kawagoe city area as guidance targets.

According to this embodiment, even if an individual point has a low score and cannot be presented to the user as a candidate destination point, an area with a certain score can be presented to the user as an area containing the candidate destination point. can be presented. Furthermore, by not presenting areas that do not have a certain score, the user is not needlessly confused.

[2. Configuration of navigation device]
Next, the configuration of the navigation device NV according to this embodiment will be explained using FIG. 7. As shown in FIG. 7, the navigation device NV includes a control unit 211, a storage device 212 such as an HDD, an input device 213 such as a keyboard, remote controller, or touch panel, a display unit 214, and a bus line 215. It is configured with an input/output interface section 220, a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, a GPS receiving section 225, a data transmitting/receiving section 226, and a wireless communication section 227. There is.

The vehicle speed sensor 221 detects the current speed of the vehicle using, for example, a speed detection process using a vehicle speed pulse obtained from the vehicle in which the navigation device NV is mounted, and outputs speed data. The angular velocity sensor 222 detects the angular velocity of, for example, a direction change of the vehicle, and outputs angular velocity data and relative azimuth data per unit time. The acceleration sensor 223 detects the acceleration of the vehicle, for example in the longitudinal direction, and outputs acceleration data per unit time. The steering angle sensor 224 detects the steering angle of the vehicle and outputs steering angle data and the like. The GPS receiving unit 225 receives navigation radio waves from GPS satellites, and receives vehicle position information (current position information) latitude, longitude, altitude data, absolute azimuth data of the direction of travel of the vehicle, and GPS speed data as GPS positioning data. etc. is output. The data transmitting/receiving unit 226 performs processing related to transmitting and receiving data with the server device via the network. The wireless communication unit 227 performs processing related to wireless road-to-vehicle communication and vehicle-to-vehicle communication.

The storage device 212 stores various programs such as an operating system and application programs (including a program for realizing a destination presentation function). Note that the various programs may be obtained from a server device or the like via a network, or may be executed by reading those recorded on a recording medium such as a CD, DVD, or USB memory. .

The storage device 212 also stores map image data for displaying a map on the display unit 214, map information used for route searching, road link information, and the like. The map information includes information that allows it to be determined to which area (city, town, village, prefecture) a point to which the navigation device NV can guide belongs.

Furthermore, the storage device 212 stores information necessary to implement the destination presentation function. For example, history information indicating the user's destination search history, point visit history (transit history), etc., and branch point information regarding branch points (information indicating the position of the branch point) are stored.

The input device 213 includes a touch panel, a keyboard, a mouse, another controller, etc., and receives input operations from the user and sends an operation signal indicating the content of the operation to the control unit 211.

The display unit 214 displays various display data under the control of the control section 211. The display unit 214 includes a graphics controller 214a, a buffer memory 214b made of a memory such as VRAM (Video RAM), and a display 214c made of a liquid crystal display or the like. In this configuration, the graphics controller 214a controls the entire display unit 214 based on control data sent from the control section 211 via the bus line 215. Further, the buffer memory 214b temporarily stores image information that can be displayed immediately. An image is then displayed on the display 214c based on the image data output from the graphics controller 214a. The display 214c displays a direction signboard screen 500 (see FIG. 4, etc.).

The control unit 211 includes a CPU 211a that controls the entire control unit 211, a ROM 211b that stores a control program and the like that controls the control unit 211 in advance, and a RAM 211c that temporarily stores various data. The control unit 211 is connected to a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, and a GPS receiving unit 225 via a bus line 215 and an input/output interface unit 220, and outputs are output from each. The entire navigation device is controlled based on speed data, angular velocity data, relative azimuth data, steering angle data, GPS positioning data, absolute azimuth data of the direction of travel of the vehicle, acceleration data, etc., and various configurations such as the display unit 214. Control the respective movements in the members.

[3. Operation example of navigation device NV]
Next, an example of the operation of the navigation device NV while the destination presentation function is in operation will be described using the flowchart of FIG.

First, the control unit 211 of the navigation device NV calculates a score of a point based on the history information recorded in the storage device 212 (step S11). Note that the control unit 211 may calculate the score by narrowing down to the current position of the vehicle and a point in the direction of travel 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 points for each area and calculates an area score (step S12).

Next, the control unit 211 determines whether or not there is an area whose area score is equal to or greater than a 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 where the area score is equal to or greater than the threshold (step S13: NO), the control unit 211 ends the process shown in the flowchart. On the other hand, if the control unit 211 determines that there is an area whose area score is equal to or greater than the threshold (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 there is a display area that includes the current position among the display areas determined in the process of step S13 (step S15). At this time, if the control unit 211 determines that there is a display area that includes the current position (step S15: YES), the control unit 211 displays a direction signboard screen 500 that displays the names of each point belonging to the display area on the display 214c. (step S16), and the process shown in the flowchart ends. On the other hand, if the control unit 211 determines that there is no display area that includes the current position (step S15: NO), the control unit 211 displays the direction signboard screen 500 that displays the name of the display area determined in the process of step S14 on the display 214c. The information is displayed (step S17), and the processing shown in the flowchart is ended.

As explained 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 "calculation means", "aggregation means", "display control means") calculates a score (an example of an "evaluation value") for a point based on historical information about the point, and aggregates the score for the area to which the point for which the score was calculated belongs, out of areas set in advance by administrative divisions. The area score (an example of a "summary evaluation value") is calculated, and information about Kawagoe City areas that have an area score of 50 or higher (an example of an "area that meets the first criteria" or a "special area") is displayed. 214c (an example of "display section 2").

Therefore, according to the navigation device NV according to the present embodiment, information regarding the Kawagoe City area that is likely to include the user's destination can be displayed.

Further, the control unit 211 (an example of a "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 when the current position is within the Kawagoe City area. The display format of information regarding the Kawagoe City area is different depending on whether the information is outside the Kawagoe City area or not. This allows the user to understand at a glance whether the current location is within the Kawagoe City area, which is likely to include the destination.

Furthermore, when the current location is within the Kawagoe City area, the control unit 211 of the navigation device NV according to this embodiment displays the names of the points "company", "convenience store", and "gas station" that belong to the Kawagoe city area. Display. With this, 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 that 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 present invention is applied to an in-vehicle navigation device NV, but the present invention can also be applied to a portable navigation device, a smartphone, a tablet terminal, a PC, etc. in which a navigation application program is installed. You can also do that.

[4. Modified example]
Next, a modification of the above embodiment will be described. Note that the modifications described below can be combined as appropriate.

[4.1. Modification example 1]
In the above embodiment, the control unit 211 calculates the area score for the area, but in addition to this, the control unit 211 may calculate the upper area score for the upper area that is higher than the area. In the above embodiment, areas were associated with the "city" level, but in this modification, the upper areas are associated with the "prefecture" level.

Figure 9 shows the scores for a total of six locations: "company," "convenience store," and "gas station" in Kawagoe City, "supermarket" and "nursery school" in Fujimino City, and "restaurant" in Nerima Ward. An example of calculation is shown. In this example, the area scores are "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 will not be 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 top area scores are "90" for the Saitama area and "10" for the Tokyo area. Here, the upper area score of the Saitama prefecture area is the threshold for determining the display area (70) (the threshold is set for determining the display area within the area and when determining the display area within the upper area). (It may be changed. In this modification, the description will be made assuming that it is not changed.) Therefore, the control unit 211 determines the Saitama Prefecture area as the display area. Then, when the current location is outside the Saitama Prefecture area, the control unit 211 displays a 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 example selects a top area when there is no area (an example of an "area that satisfies the first criterion") with an area score (an example of an "aggregated evaluation value") of "50" or more. Of these, for the top area to which each point for which the score (an example of an "evaluation value") was calculated belongs, the scores are aggregated to calculate the top area score (an example of a "top aggregated evaluation value"), and the top area score is " 70" or above (an example of a "special high-ranking area that meets the second criterion"), where the current location is not included in the Saitama Prefecture area, displaying guidance information that indicates the Saitama Prefecture area as the guidance target. A 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 in FIG. It is determined whether there is a corresponding point (an example of a point whose evaluation value satisfies the third criterion), and if there is a corresponding point, the point is determined to be a display point (an example of a “special point”). When the current position of the vehicle is outside the display area, the control unit 211 displays information representing the display point along with guidance information representing the display area as a guidance target.

For example, in the example of FIG. 11, the control unit 211 determines the Kawagoe City area as the display area, and since the score of the "company" belonging to the Kawagoe City area is "55" ("40" or higher), the control unit 211 selects the display point as the display area. decide. Then, when the current position of the vehicle is outside the Kawagoe City area, the control unit 211 displays a direction signboard screen 500 showing "company" and directions to the Kawagoe City area, as shown in FIG.

That is, the control unit 211 of this modification example controls Kawagoe City to which a "company" whose score (an example of an "evaluation value") is a point of "40" or higher (an example of a "special point that satisfies the third criterion") belongs to. If the current location is outside the area (an example of a "special area"), information representing the "company" is displayed along with guidance information representing the Kawagoe City area as the guidance target. This allows the user to easily understand what kind of area the Kawagoe City area is since not only the guidance information representing the Kawagoe City area as the guidance target but also information representing the "company" is displayed.

[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 using the following equation (1).
Threshold = (1/Number of areas for which area scores were calculated) x 100 (1) Formula For example, in the example in Figure 13, the "number of areas for which area scores were calculated" are three areas: Kawagoe City, Fujimino City, and Tokorozawa City. Therefore, the threshold value is "33" (the processing below the decimal point may be rounded down, rounded up, rounded off, etc.). Then, the control unit 211 determines the Kawagoe City area and Tokorozawa City area, which are areas with area scores equal to or higher than the threshold value "33", as display areas.

FIG. 14 is a diagram showing an example of the positional relationship between the Kawagoe City area and Tokorozawa City area, which are display areas, and points belonging to each area. That is, if you turn right at junction F2 in the direction of travel of the vehicle, you will be heading towards the Kawagoe City area, and the Kawagoe City area includes "companies" and "convenience stores." On the other hand, if you go straight at junction F2, you will be heading towards the Tokorozawa City area, and the "station" and "restaurant" belong to the Tokorozawa City area. When the positional relationship between the two display areas, Kawagoe City area and Tokorozawa City area, is as shown in FIG. 14, the control unit 211 displays the Tokorozawa City area as a guidance target in the straight direction, as shown in FIG. In addition to displaying guidance information, a direction signboard screen 500 is displayed that displays guidance information representing the Kawagoe City area as a guidance target in the right turn direction. Thereby, multiple areas that are likely to include the destination can be presented to the user.
