[0012] An embodiment of the present invention will be described with reference to FIG.

[0013] As shown in FIG. 1, the display control device 1 includes a calculation means 111A, a collection means 111B, and a display control means 111C, and is connected to a display unit 2.

[0014] The calculation means 111A calculates an evaluation value for a location based on history information about the location. The history information about a location is, for example, information indicating a history of a user searching for the location, information indicating a history of a user visiting or passing through the location, etc. The evaluation value is, for example, a numerical value that indicates the degree of likelihood that the location will be the user's destination, and the higher the numerical value, the higher the likelihood that the location will be the user's destination.

[0015] The tallying means 111B calculates a total evaluation value by tallying the evaluation values ​​for the area to which the point for which the evaluation value was calculated belongs, among the pre-set areas. The pre-set area is, for example, an administrative district (such as a city, ward, town, or village), but can also be set arbitrarily.

[0016] The display control means 111C causes information about special areas, which are areas whose aggregated evaluation values ​​satisfy a first criterion, to be displayed on the display unit 2. The first criterion is, for example, a preset threshold value for comparison with the aggregated evaluation value.

[0017] Therefore, the display control device 1 can display information about special areas that are highly likely to include the user's destination.

[0018] The display control device 1 may further include a 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.

[0019] The display control means 111C may display information about the special area in different ways depending on whether the current location is inside or outside the special area, allowing the user to know at a glance whether the current location is inside a special area that is likely to include the destination.

[0020] Furthermore, when the current location is within a special area, the display control means 111C may display information representing a point belonging to the special area. The information representing the point may be, for example, a name representing the point (such as a facility name), an administrative notation representing the point (for example, 1-1-1, XX-cho, XX-city, XX-prefecture), an icon representing the point, etc. This allows the user to grasp at a glance the points belonging to the special area when the current location is within a special area that is likely to include the destination.

[0021] Furthermore, when the current location is outside the special area, the display control means 111C may display guidance information indicating the special area as a guidance target, thereby making it easier for the user to move in the direction of the special area that is likely to include the destination.

[0022] Furthermore, the display control means 111C may display more information about special areas than information about areas whose aggregated evaluation values ​​do not satisfy the first criterion. This allows information about special areas that are likely to be destinations to be displayed more than information about areas whose aggregated evaluation values ​​are unlikely to be destinations, allowing the user to obtain more information that is likely to be useful. Note that displaying more information about special areas than information about areas whose aggregated evaluation values ​​do not satisfy the first criterion includes displaying a certain amount of information about special areas and not displaying any information about areas whose aggregated evaluation values ​​do not satisfy the first criterion.

[0023] A higher-level area including multiple areas may be preset. For example, if an area identified by city, ward, town, or village name is set (e.g., Kawagoe City), an area identified by prefecture name (e.g., Saitama Prefecture) may be set as the higher-level area. If there is no area whose aggregated evaluation value satisfies the first criterion, the aggregation means 111A may aggregate the evaluation values ​​of the higher-level areas to which each location for which an evaluation value has been calculated belongs to calculate a higher-level aggregated evaluation value. If the current location is not included in a special higher-level area whose higher-level aggregated evaluation value satisfies the second criterion, the display control means 111C may display guidance information indicating the special higher-level area as a guidance target. The second criterion may be, for example, a threshold value preset for comparison with the higher-level aggregated evaluation value. This makes it easier for the user to move toward a special higher-level area that is likely to include the destination.

[0024] Furthermore, when the current location is outside a special area to which a special point whose evaluation value satisfies a third criterion belongs, the display control means 111C may display information representing the special point together with guidance information representing the special area as a guidance target. The third criterion is, for example, a preset threshold value 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 points that are likely to be the destination is displayed. [Example]

[0025] Next, a specific example corresponding to the above-described embodiment will be described.

[0026] The following embodiments will be described with reference to Figures 2 to 8. The embodiments described below are examples in which the present invention is applied to a navigation device mounted on a vehicle.

[0027] [1. Overview of the navigation device] First, an outline of the destination presentation function of the navigation device in this embodiment will be described. The destination presentation function is a function that, when a user is driving without setting a destination, estimates destination candidate points or areas including destination candidate points from points that the user has visited or searched for in the past and displays them on a directional sign on the screen.

[0028] For the purpose of the destination presentation function, the navigation device routinely records history information indicating the search history of destinations, visit (via) history, etc. (regardless of whether the destination presentation function is in operation or not).

[0029] The navigation device calculates a score (an example of an "evaluation value") for each location based on history information using a conventionally known method, as shown in Figure 2, to estimate candidate destination locations for the user. The higher the score, the more likely the location is the user's destination. Therefore, locations with a score above a certain level can be presented to the user as candidate destination locations. If there are many locations for which scores are to be calculated, the score may be calculated by excluding locations that are outside a predetermined range of distance or travel time from the current location of the vehicle (navigation device) or locations that have been searched for or visited (passed by) for a predetermined period of time or more. Figure 2 shows an example of scores calculated for five locations: a "company," a "convenience store," and a "gas station" in Kawagoe City, and a "supermarket" and a "nursery school" in Fujimino City.

[0030] The navigation device calculates an area score for each area to which a 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 below a certain level, the point is unlikely to be a candidate destination point for the user, and it is therefore desirable not to present the point to the user. Instead, if the area score is above a certain level, the navigation device will present the area to the user as an area to which a candidate destination 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 about areas with an area score of 50 or above (an example of the "first criterion") on a directional sign.

[0031] FIG. 3 is a diagram showing the positional relationship of points belonging to the Kawagoe City area with an area score of 50 or more, and the position of the vehicle is represented by 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 directional sign 500 indicating that the straight-ahead direction is toward Kawagoe City, as shown in FIG. 4. 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 directional sign 500, as shown in FIG. 6. Specifically, as shown in FIG. 5, "company" is located in the straight-ahead direction from junction F1, "convenience store" is located in the right-turn direction from junction F1, and "gas station" is located in the left-turn direction from junction F1. Accordingly, directional sign 500 also displays information indicating "company" in the straight-ahead direction, information indicating "convenience store" in the right-turn direction, and information indicating "gas station" in the left-turn direction. In other words, 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 with the Kawagoe City area as the guidance target, and on the other hand, if the current location is within the Kawagoe City area, the navigation device displays guidance information with points belonging to the Kawagoe City area as the guidance target.

[0032] According to this embodiment, even if an individual point has a low score and cannot be presented to the user as a destination candidate, an area with a certain score can be presented to the user as an area containing a destination candidate. Furthermore, by not presenting areas that do not have a certain score, the user is not unnecessarily confused.

[0033] [2. Configuration of navigation device] Next, the configuration of the navigation device NV according to this embodiment will be described with reference to Fig. 7. As shown in Fig. 7, the navigation device NV includes a control unit 211, a storage device 212 including an HDD or the like, an input device 213 including a keyboard, a remote controller, a touch panel or the like, a display unit 214, a bus line 215, an input / output interface unit 220, a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, a GPS receiving unit 225, a data transmitting / receiving unit 226, and a wireless communication unit 227.

[0034] The vehicle speed sensor 221 detects the current speed of the vehicle using a speed detection process using, for example, a vehicle speed pulse acquired from the vehicle equipped with the navigation device NV, and outputs speed data. The angular velocity sensor 222 detects, for example, the angular velocity of the vehicle, which is a change in direction, and outputs angular velocity data and relative direction data per unit time. The acceleration sensor 223 detects, for example, the acceleration of the vehicle in the longitudinal direction, and outputs acceleration data per unit time, etc. The steering angle sensor 224 detects the steering angle of the vehicle and outputs steering angle data, etc. The GPS receiver 225 receives navigation radio waves from GPS satellites and outputs GPS positioning data, such as latitude, longitude, and altitude data, which are vehicle position information (current position information), absolute direction data of the vehicle's traveling direction, and GPS speed data. The data transmitter / receiver 226 performs processing related to data transmission and reception with a server device via a network. The wireless communication unit 227 performs processing related to wireless road-to-vehicle communication and wireless vehicle-to-vehicle communication.

[0035] 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 acquired, for example, from a server device or the like via a network, or may be read and executed from a recording medium such as a CD, DVD, or USB memory.

[0036] The storage device 212 also stores map image data for displaying a map on the display unit 214, map information used for route searches, road link information, etc. The map information includes information that enables the navigation device NV to determine to which area (city, ward, town, village, prefecture) a point that can be guided by the navigation device NV belongs.

[0037] Furthermore, the storage device 212 stores information necessary to realize the destination presentation function, such as history information indicating the user's destination search history and point visit history (route history), and branch point information (information indicating the position of the branch point).

[0038] The input device 213 is configured with a touch panel, a keyboard, a mouse, other controllers, etc., and receives input operations from the user and transmits operation signals indicating the operation contents to the control unit 211.

[0039] The display unit 214 displays various display data under the control of the control unit 211. The display unit 214 is configured to include a graphics controller 214a, a buffer memory 214b consisting of a memory such as a VRAM (Video RAM), and a display 214c consisting 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 unit 211 via a bus line 215. The buffer memory 214b temporarily stores image information that can be displayed immediately. Images are then displayed on the display 214c based on the image data output from the graphics controller 214a. The display 214c displays a directional sign screen 500 (see FIG. 4, etc.).

[0040] The control unit 211 is made up of a CPU 211a that controls the entire control unit 211, a ROM 211b in which control programs and the like that control the control unit 211 are stored 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 controls the entire navigation device and the operations of various components such as a display unit 214 based on speed data, angular velocity data, relative direction data, steering angle data, GPS positioning data, absolute direction data of the vehicle's traveling direction, acceleration data, and the like output from each of these sensors.

[0041] [3. Example of operation 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 with reference to the flowchart of FIG.

[0042] First, the control unit 211 of the navigation device NV calculates the score of a location 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 the locations to the current location of the vehicle and the locations in the direction of travel of the vehicle. Furthermore, a conventionally known method can be used as a method for calculating the score.

[0043] Next, the control unit 211 tallies the scores of the points for each area and calculates the area score (step S12).

[0044] 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 processing 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 greater than the threshold value (step S13: NO), it ends the processing 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 value (step S13: YES), it determines that area as a display area (an example of a "special area") (step S14).

[0045] Next, the control unit 211 determines whether or not any of the display areas determined in the processing of step S13 includes a display area that includes the current position (step S15). If the control unit 211 determines that a display area that includes the current position exists (step S15: YES), the control unit 211 causes the display 214c to display a direction sign screen 500 that displays the names of locations that belong to the display area (step S16), and ends the processing shown in the flowchart. On the other hand, if the control unit 211 determines that no display area includes the current position exists (step S15: NO), the control unit 211 causes the display 214c to display a direction sign screen 500 that displays the name of the display area determined in the processing of step S14 (step S17), and ends the processing shown in the flowchart.

[0046] As described above, according to the navigation device NV (an example of a "display control device 1") of this embodiment, the control unit 211 (an example of a "calculation means," "aggregation means," or "display control means") calculates a score (an example of an "evaluation value") for a location based on historical information about the location, aggregates the scores for the areas to which the location for which the score was calculated belongs among the areas previously set by administrative districts to calculate an area score (an example of an "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 an "area that meets the first criterion" or a "special area") on the screen of the display 214c (an example of a "display unit 2").

[0047] Therefore, the navigation device NV according to this embodiment can display information about the Kawagoe area, which is highly likely to include the user's destination.

[0048] Furthermore, the control unit 211 (an example of a "current location acquisition means") of the navigation device NV according to this embodiment acquires information indicating the current location of the navigation device NV, and displays information about the Kawagoe City area in different ways depending on whether the current location is within the Kawagoe City area or outside the Kawagoe City area. This allows the user to know at a glance whether the current location is within the Kawagoe City area, which is likely to include the destination.

[0049] 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 points that belong to the Kawagoe city area, such as "company," "convenience store," and "gas station." This allows the user to grasp at a glance the points that belong to the Kawagoe city area when the current location is within the Kawagoe city area, which is likely to include the destination.

[0050] Furthermore, when the current location is outside the Kawagoe area, the control unit 211 of the navigation device NV according to this embodiment displays guidance information indicating the Kawagoe area as a guidance target, which makes it easier for the user to move in the direction of the Kawagoe area, which is likely to include the destination.

[0051] In this embodiment, the present invention has been described as being applied to an in-vehicle navigation device NV, but it can also be applied to portable navigation devices, smartphones, tablet terminals, PCs, etc. on which a navigation application program is installed.

[0052] [4. Modifications] Next, modifications of the above embodiment will be described. The modifications described below can be combined as appropriate.

[0053] [4.1. Variation 1] In the above embodiment, the control unit 211 calculates an area score for each area, but in addition, it may calculate a higher-level area score for each higher-level area that is a higher-level area. In the above embodiment, areas are associated with the "city, ward, town, or village" level, but in this modified example, higher-level areas are associated with the "prefecture" level.

[0054] Figure 9 shows an example in which scores are calculated for six locations: a "company," a "convenience store," and a "gas station" in Kawagoe City, a "supermarket" and a "daycare center" in Fujimino City, and a "restaurant" in Nerima Ward. 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. If 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.

[0055] Therefore, in this modified example, the control unit 211 calculates a higher-level area score for the higher-level area of ​​the area. In the example of FIG. 9, the higher-level area score is "90" for the Saitama prefecture area and "10" for the Tokyo metropolitan area. Here, since the higher-level area score for the Saitama prefecture area is equal to or greater than the threshold value "70" for determining the display area (the threshold may be different when determining the display area within an area and when determining the display area within a higher-level area. In this modified example, it is described as not being changed), 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 directional sign screen 500 indicating the direction of the Saitama prefecture area, as shown in FIG. 10.

[0056] That is, in this modified example, when there is no area (an example of an "area satisfying the first criterion") with an area score (an example of an "aggregated evaluation value") of 50 or more, the control unit 211 calculates a top area score (an example of a "top aggregated evaluation value") by aggregating the scores of the top areas to which each point for which a score (an example of an "evaluation value") has been calculated belongs, and when the current location is not included in the Saitama prefecture area, which is an area with a top area score of 70 or more (an example of a "special top area satisfying the second criterion"), displays a directional sign screen 500 that displays guidance information indicating the Saitama prefecture area as the guidance target. This makes it easier for the user to move in the direction of the Saitama prefecture area, which is likely to include the destination.

[0057] [4.2. Variation 2] In this modified example, when the control unit 211 determines "NO" in the processing of step S15 in Fig. 8, it further determines whether there is a point within the display area that has a score of "40" or more (an example of a "point whose evaluation value satisfies the third criterion"), and if there is such a point, it determines that point as a display point (an example of a "special point"). Then, when the current position of the vehicle is outside the display area, the control unit 211 displays information indicating the display point together with guidance information that indicates the display area as a guidance target.

[0058] 11, the control unit 211 determines the Kawagoe city area as the display area, and also determines the "company" that belongs to the Kawagoe city area as the display location because the score is "55" (40 or more). Then, when the current location of the vehicle is outside the Kawagoe city area, the control unit 211 displays a direction sign screen 500 indicating the direction of the "company" and the Kawagoe city area, as shown in FIG.

[0059] That is, in this modified example, when the current location is outside the Kawagoe City area (an example of a "special area") to which the "company" belongs, which is a location (an example of a "special location satisfying the third criterion") with a score (an example of an "evaluation value") of 40 or more, the control unit 211 displays information representing the "company" along with guidance information representing the Kawagoe City area as the guidance target. This makes it easier for the user to understand what kind of area the Kawagoe City area is, as not only the guidance information representing the Kawagoe City area as the guidance target but also the information representing the "company" is displayed.

[0060] [4.3. Variation 3] This modification is a modification in which control unit 211 determines a plurality of areas as the display area. In this modification, a threshold value for determining the display area is calculated by the following equation (1). Threshold = (1 / number of areas for which area scores are calculated) × 100 (1) 13, the "number of areas for which area scores have been calculated" is three: Kawagoe City, Fujimino City, and Tokorozawa City, so the threshold is "33" (decimal points can be rounded down, rounded up, rounded to the nearest whole number, or any other method). Then, the control unit 211 determines the Kawagoe City area and Tokorozawa City area, which are areas with area scores equal to or greater than the threshold "33," as display areas.

[0061] 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 locations belonging to each area. That is, turning right at branch point F2 in the vehicle's direction of travel leads to the Kawagoe City area, which includes "companies" and "convenience stores." On the other hand, going straight at branch point F2 leads to the Tokorozawa City area, which includes "stations" and "restaurants." 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 displays guidance information indicating the Tokorozawa City area as a guidance target in the direction of travel, as shown in FIG. 15, and also displays a directional sign screen 500 that displays guidance information indicating the Kawagoe City area as a guidance target in the direction of a right turn. This allows the user to be presented with multiple areas that are likely to include the destination. [Explanation of symbols]
