Description

The present application relates to a technical field such as an information processing device that notifies a user of a destination.

Conventionally, there are people who want to move to a destination without setting a destination in the navigation device. Especially for destinations that I have visited in the past and have a rough idea of their location, I find it bothersome to set the destination. Some of these people start moving without using the route search / route guidance function based on the destination setting, but if the location of the destination is only roughly known, the road around the destination You may get lost.

Under such circumstances, a destination estimation function that estimates a destination intended by a user without setting a destination by the user is drawing attention. The destination estimation function estimates the destination intended by the user and notifies the position by image or voice. As a result, the user can grasp the position of the destination that he / she remembers, and can reach the destination without setting the destination.

However, when estimating the destination intended by the user, if the past destination is treated as a candidate for the destination, a point far away from the current position is also a candidate for the destination, so the target to be notified is There will be too many to tell the user the right candidates.

In response to these problems, the technique described in Patent Document 1 aims to make it easier for the user to find a new favorite facility, and when displaying the position of the new facility for the user, the object to be displayed is set. It is limited to those included in the user's activity range (set based on the user's movement history or home location). As a result, only facilities within the range of activities that users can easily visit are displayed without notifying the location of new facilities innumerably.

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

As shown in FIG. 1, the information processing device 1 includes a group area setting means 111A, a current position information acquisition means 111B, a notification control means 111C, a current user identification information acquisition means 111D, and a current companion identification information acquisition means. It includes 111E and the current date and time information acquisition means 111F. Further, the notification control means 111C is connected to the notification means 2.

The group area setting means 111A sets a plurality of group areas based on the point history information regarding the position information indicating the points where the user has shown interest in the past. The points that the user has been interested in in the past are, for example, the points that the user has visited in the past or the points that the user has searched for in the past.

The current position information acquisition unit 111B acquires the current position information indicating the current position of the user (the current position of the user using the information processing device 1 and the current position of the information processing device 1).

The notification control means 111C notifies the position information indicating a point in the first group area including the current position among the plurality of group areas set by the group area setting means 111A in the past. To notify. That is, when the current user is in any of the group areas, the position information including the points in the group area indicating the points where the user has been interested in the past is notified. The notification means is composed of, for example, an image display device or a voice output device. When the notification means is an image display device, the notification control means 111C causes the image display device to display an image representing the position information. When the notification means is a voice output device, the notification control means 111C causes the voice output device to output a voice representing the position information.

As described above, according to the operation of the information processing device 1 according to the present embodiment, when the user is in any of the group areas set based on the position of the point of interest in the past, the group area is set. Position information indicating the included points is notified. That is, the information processing device 1 estimates the point at which the user has been interested in the past as the current destination and notifies the user. As a result, the information processing device 1 notifies the position of the destination intended by the user without the user setting the destination, and causes the user who remembers the position of the destination to reach the destination. Can be done.

When the notification control means 111C notifies the position information indicating a point in the first group area in which the user has been interested in the past in association with any branch direction at the branch point of the route on which the user moves. There is. For example, if the notification control means 111C advances to the left at the branch point, it notifies that the user will arrive at the point X that has been interested in the past by using an image or a voice. As a result, the user can grasp in which direction the branch point should be advanced to reach the destination.

The notification control means 111C may notify the position information indicating a representative point in the second group area different from the first group area in association with any branch direction at the branch point. For example, if the current user is included in the first group area and the notification control means 111C advances to the right at the branch point, the notification control means 111C includes a second point Y including the point Y in which the user has been interested in the past. Notify the arrival of the representative point of the group area by using images and sounds. As a result, the user can grasp in which direction the branch point can be advanced to the second group area different from the first group area. The representative point may be a point (for example, point Y) in which any user included in the second group area has shown an interest in the past, a famous spot in the second group area, or a central point. (Position of the center of gravity) may be used.

Further, when the point history information is information indicating a visited point that the user has visited in the past, the point history information is associated with the user identification information that identifies the user who visited the visited point. The current user identification information acquisition means 111D has acquired the current user identification information for identifying the current user, and the group area setting means 111A has acquired the current user identification information acquisition means 111D. The group area is set based on the point history information associated with the user identification information that identifies the same user as the user identified by the person identification information, and the notification control means 111C is the group area setting means 111A. In some cases, only the position information indicating the visited point indicated by the point history information when the group area is set is notified. In this case, the group area is set only for the visited points visited by the current user in the past, and the position information indicating the position is notified only for the visited points included in the first group area including the current position. That is, the position information indicating the visited point visited by a user other than the current user is not notified. Therefore, it is possible to notify the location information suitable for the current user.

Further, when the point history information is information indicating a visited point that the user has visited in the past, the point history information is used as the user identification information for identifying the user who visited the visited point and the user. The current user identification information acquisition means 111D acquires the current user identification information that identifies the current user, and is currently associated with the companion identification information that identifies the companion who visited the visited point. The companion identification information acquisition means 111E acquires the current companion identification information that identifies the companion who is accompanied by the user, and the group area setting means 111A is the same as the user currently identified by the user identification information. Group based on the point history information to which the user identification information that identifies the user and the companion identification information that identifies the same companion as the companion currently identified by the companion identification information are associated with each other. When the area is set, the notification control means 111C may notify only the position information indicating the visited point indicated by the point history information when the group area setting means 111A sets the group area. In this case, the group area is set only for the visit points that the current user and the current companion have visited together in the past, and the position indicating the position only for the visit point included in the first group area including the current position. Information is notified. That is, the position information indicating the position of the visited point visited by another user or the visited point visited by the user together with another companion is not notified. Therefore, it is possible to notify the location information suitable for the user and the companion.

Furthermore, the point history information is associated with date and time information indicating the date and time when the visited point was visited, and the current date and time information acquisition means 111F acquires the current date and time information indicating the current date and time, and the group area setting means 111A. May set the group area based on the point history information associated with the date and time information indicating the date and time corresponding to the current date and time indicated by the current date and time information. The date and time information is, for example, information indicating at least one of a date, a day of the week, and a time. The date and time corresponding to the current date and time can be considered as, for example, if the current date and time is Monday, any Monday in the past corresponds to the date and time. Similarly, if the current date and time is April 3, then any of the past April 3 is considered the corresponding date and time, and if the current date and time is 9:00 am, any of the past 9 am The time (in the case of time, you may allow a margin of the specified time before and after) is considered as the corresponding date and time, and if the current date and time is Wednesday 5 pm, any of the past Wednesday 5 pm corresponds to the date and time Can be considered as. Since users often act according to schedules determined by dates, days of the week, time, etc., the destinations presented to users are narrowed down according to the date and time when the destination was visited in the past, in line with the user's request. The possibility of being able to make a presentation is improved.

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

Examples will be described with reference to FIGS. 2-FIG. 14. The examples described below are examples in which the present invention is applied to an in-vehicle navigation device mounted on a vehicle.

[1. Overview of navigation device]
First, the outline of the characteristic destination presentation function of the navigation device in this embodiment will be described. The destination presentation function is a function that estimates a destination candidate from the points that the user has visited in the past and displays it on the direction signboard on the screen when the user is traveling without setting the destination. is there.

The navigation device routinely records the travel route of the vehicle for the destination presentation function (whether or not the destination presentation function is activated). For example, as shown in FIG. 2, the navigation device first moves the travel route R1 from the start point S1 of the travel to the end point G1 (destination P1) in an array of latitude and longitude during the first travel. Record based on road links, etc.

Similarly, during the next travel, the travel route is recorded, and during the travel, it is determined whether the vehicle is traveling on the travel route R1 that was previously traveled, and if the vehicle deviates from the travel route R1 as shown in FIG. FIG. 3 shows how the own vehicle icon C indicating the position of the own vehicle deviates from the traveling path R1), and this point is recorded as a branch point B1 as shown in FIG. Further, with respect to the branch point B1, information indicating which direction the vehicle has traveled (right in FIG. 4) and information indicating the traveling end point G2 (destination P2) at that time are recorded.

Further, in the next traveling time, the traveling route is similarly recorded, and during the traveling, it is determined whether the vehicle is traveling on the traveling route R1 or the traveling route R2 that has been traveled in the past, and the vehicle deviates from the past traveling route. Is recorded as a branch point B2 as shown in FIG. Further, with respect to the branch point B2, information indicating which direction the vehicle has traveled (left in FIG. 5) and information indicating the traveling end point G2 (destination P3) at that time are recorded.

Then, when the own vehicle is at the position indicated by the own vehicle icon C (the position before the branch point B1) as shown in FIG. 6, for example, the navigation device is shown in FIG. The direction signboard 500 regarding the branch point B1 as shown in 7 is displayed. That is, the navigation device estimates the past destination as the current destination, and indicates that the right direction is the direction of the destination P2 and the left direction is the direction of the destination P1 and the destination P3. Display 500. Similarly, as shown in FIG. 8, the navigation device, for example, when the own vehicle is at the position indicated by the own vehicle icon C (the position in front of the branch point B2), the navigation device has the branch point B2 as shown in FIG. The direction signboard 500 is displayed. That is, the direction signboard 500 indicating that the right direction is the direction of the destination P1 and the left direction is the direction of the destination P3 is displayed. As a result, even when the user is traveling without setting a destination, he / she can know the direction of the destination that he / she remembers and can freely travel.

On the other hand, if all past destinations are treated as estimation candidates, it may not be possible to present a destination suitable for the current driving situation, such as displaying one that is too far from the current position. .. Therefore, the navigation device divides the points (destination) visited in the past into groups based on the position, sets each as an action area, and determines whether or not the own vehicle is in any of the action areas. By displaying only the destination in the action area, the display of the destination that is too far from the current position is suppressed.

FIG. 10A shows how the action areas A1 and A2 are set based on the points (destination P) that the user has visited in the past. The navigation device sets each action area so that the area is smaller than the preset maximum area. This is because if an excessively large range is set as the action area, as a result, a point that is too far from the current position is also displayed as a destination candidate. As a method of grouping points (destination) visited in the past based on the position, a conventionally known grouping method or clustering method can be adopted. In addition, when setting the action area, it is suitable for the current usage situation by filtering the points visited in the past using information such as the date, time, driver, passengers, etc. related to the points visited in the past. You can set the action area. For example, as shown in FIG. 10B, by filtering the grouping target only to the points visited by the current driver, only the destination candidates suitable for the current driver can be displayed. ..

As a result, when referring to the history, it can be determined that there is no passenger and the driver has visited alone.

[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. Before the destination presentation function is activated, the input of the current driver identification information for identifying the current driver and the current passenger identification information for identifying the current passenger is received and recorded in the storage device 212. And.

First, the control unit 211 of the navigation device NV acquires the driving information (step S11). The driving information includes the current driver identification information and the current passenger identification information recorded in the storage device 212 before the destination presentation function is activated, and the current date and time (year / month / day / day of the week / hour / minute / second). Contains current date and time information indicating.

Next, the control unit 211 performs an action area setting process (step S12). Here, the action area setting process will be described with reference to FIG.

First, the control unit 211 refers to the destination history information recorded in the storage device 212, and corresponds to the driver identification information that identifies the same driver as the driver indicated by the current driver identification information included in the driving information. The attached destination is extracted (step S31).

Next, the control unit 211 refers to the destination history information recorded in the storage device 212, and further, from the destinations extracted in the process of step S31, the rider indicated by the current passenger identification information included in the driving information. The destination to which the passenger identification information for identifying the same passenger as the person is associated is extracted (step S32).

Next, the control unit 211 refers to the destination history information recorded in the storage device 212, and further, from the destinations extracted in the process of step S32, the day of the week indicated by the current date and time information included in the operation information is the same. And, the destination to which the date and time information indicating the date and time indicating the date and time within a predetermined range is associated with the time indicated by the current date and time information is extracted (step S33). Here, it was decided to extract destinations that have the same day of the week and time (the times are close), but the destinations should be extracted based on the date and time information from other viewpoints (date, etc.). May be.

Next, the control unit 211 refers to the destination history information recorded in the storage device 212, and groups the destinations extracted in the process of step S33 based on the position (step S34). As the grouping method, a conventionally known method can be adopted.

Next, the control unit 211 refers to the destination history information recorded in the storage device 212, and sets an action area for each group based on the positions of the destinations grouped in the process of step S34 (step S35). ), End the action area setting process.

Returning to FIG. 12, the control unit 211 determines whether or not the current position indicated by the vehicle position information is included in any of the action areas set in the process of step S12 (step S13). At this time, the control unit 211 waits while the current position is not included in any action area (step S13: NO), and if it is determined that the current position is included in any action area (step S13: NO). S13: YES), then it is determined whether or not it is the display timing of the direction signboard 500 (step S14). For example, if the current position is approaching a predetermined distance (400 m) from the branch point, the control unit 211 determines that it is the display timing of the direction signboard 500.

When the control unit 211 determines that it is not the display timing of the direction signboard 500 (step S14: NO), the control unit 211 shifts to the process of step S13. On the other hand, when the control unit 211 determines that it is the display timing of the direction signboard 500 (step S14: YES), the control unit 211 selects the destination to be displayed on the direction signboard 500 from the destination candidates in the action area. .. Specifically, the control unit 211 passes through the next branch point from the destinations narrowed down by the processes of steps S31 to S33 in FIG. 13 with reference to the branch point information of the next branch point. And select the destination you visited. When the number of destinations to be selected is large (the number that cannot be displayed on the direction signboard 500), the destinations for the predetermined number of the most recently visited (the number that can be displayed on the direction signboard 500) are selected.

Next, the control unit 211 generates directional signboard display data representing the directional signboard 500 based on the destination selected in the process of step S15 (step S16).

Next, the control unit 211 causes the display 214c to display the direction signboard 500 based on the direction signboard display data generated in the process of step S16 (step S17).

Next, the control unit 211 determines whether or not the vehicle has passed the branch point displaying the direction sign 500 (step S18). At this time, the control unit 211 waits until it passes the branch point displaying the direction signboard 500 (step S18: NO), and if it determines that it has passed the branch point displaying the direction signboard 500 (step S18: NO). YES), the process proceeds to step S13.

As described above, according to the navigation device NV according to the present embodiment, the user can use the control unit 211 (an example of "group area setting means", "current position information acquisition means", and "notification control means"). Based on destination location information (an example of "point history information") that indicates destinations visited in the past, multiple destinations visited in the past are divided into multiple groups based on the location of the destination, and the group An action area (an example of "group area") including destinations divided into the relevant group is set for each, and the vehicle position information (an example of "current position information") indicating the current position of the user is acquired. When the current position is included in any of the action areas, a direction signboard 500 (an example of "position information") indicating the position of the destination included in the action area is displayed on the display 214c (an example of "notification means"). Let me.

Therefore, according to the navigation device NV according to the present embodiment, when the user is in any action area set based on the position of the destination visited in the past, the position of the destination included in the action area. The direction signboard 500 indicating is displayed. That is, the navigation device NV estimates the destination visited by the user in the past as the current destination intended by the user and displays it to the user. As a result, the navigation device NV can display the position of the destination intended by the user without the user setting the destination, and allow the user who remembers the position of the destination to reach the destination. it can.

Further, the control unit 211 of the navigation device NV according to the present embodiment displays the direction signboard 500 at the branch point in the route on which the current user travels. That is, the position of the destination included in the action area including the current position is displayed in association with any branch direction at the branch point. As a result, the user can grasp in which direction the branch point should be advanced to reach the destination.

Further, the navigation device NV according to the present embodiment uses the destination position information as the driver identification information (“example” of the “user”) that identifies the driver (an example of the “user”) who visited the destination (an example of the “visit point”). The control unit 211 (an example of the "current user identification information acquisition means") identifies the current driver ("current user identification") in association with the current driver identification information (an example of the "user identification information"). An action area based on the destination location information associated with the driver identification information that identifies the same driver as the driver identified by the acquired current user identification information (an example of information). Is set, and only the destination indicated by the destination position information based on the setting of the group area is displayed on the direction sign 500. As a result, the action area is set only for the destinations visited by the current driver in the past, and only the destinations included in the action area including the current position are displayed on the direction signboard 500. That is, destinations visited by drivers other than the current driver are not displayed. Therefore, it is possible to display a destination suitable for the current driver.

Further, the navigation device NV according to the present embodiment uses the destination position information as the driver identification information for identifying the driver who visited the destination and the passenger (“accompanied person”) who visited the destination together with the driver. An example of the control unit 211 (“current user identification information acquisition means” and “current companion identification information acquisition means”” in association with the passenger identification information (an example of “accompaniment identification information”) that identifies (one example). ) Acquires the current driver identification information that identifies the current driver, and identifies the current passenger (an example of "accompaniment") who is in the same vehicle as the current driver. Driver identification information that acquires information and identifies the same driver as the driver currently identified by the driver identification information, and identifies the same passenger as the passenger currently identified by the passenger identification information. The action area is set based on the destination destination location information to which the companion identification information is associated with each other, and only the destination indicated by the destination location information based on the action area is displayed on the direction sign 500. To do. As a result, the action area is set only for the destinations that the current driver and the current passenger have visited together in the past, and only the destinations included in the action area including the current position are displayed on the direction signboard 500. That is, the destinations visited by other drivers and the destinations visited by the current driver with other passengers are not displayed. Therefore, it is possible to display a destination suitable for the current driver and the current passenger.

Furthermore, the navigation device NV according to the present embodiment associates the destination position information with the date and time information indicating the date and time when the destination is visited, and the control unit 211 (an example of the "current date and time information acquisition means") , Acquires the current date and time information indicating the current date and time, and sets the action area based on the destination position information associated with the date and time information indicating the date and time corresponding to the current date and time indicated by the current date and time information. As a result, by narrowing down the destinations to be displayed on the direction signboard 500 according to the date and time when the destinations were visited in the past, the possibility that the destinations can be displayed according to the user's request is improved.

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 destination (point) that the user has visited in the past is estimated to be the current destination and displayed on the direction signboard 500, but instead of or in addition to this, the destination signboard 500 is displayed. A point that the user has searched for in the past may be estimated as the current destination and displayed on the direction signboard 500. In this case, the control unit 211 records the search history when the user searches for a point in the storage device 212 as the search history information. The search history information corresponds to, for example, information indicating the name, position, and genre of the searched point, information indicating the search date and time, identification information for identifying the driver when searching, and passenger identification information for identifying the passenger. The information is attached. Then, the destination to be displayed may be filtered based on the associated information.

[4.2. Modification 2]
In the above embodiment, the control unit 211 extracts the driver, the passenger, and the destination whose date and time are the same as the current driver, passenger, and date and time (including those close to the date and time) when the destination is visited. Although it is intended to be displayed on the direction signboard 500, a destination in which at least one of the driver, the passenger, and the date and time is the same may be displayed on the direction signboard 500. Further, instead of or in addition to this, the control unit 211 extracts a destination in which the number of passengers when visiting the destination is the same as the current number of passengers and displays it on the direction signboard 500. You may do it. As a result, the possibility that the display can be displayed according to the user's request is improved.

[4.3. Modification 3]
In the above embodiment, the direction signboard 500 is displayed at the branch point in the route on which the current user moves. However, instead of or displaying the direction signboard 500, the display content of the direction signboard 500 is voiced. It may be output with. That is, the position of the destination included in the action area including the current position is output by voice in association with any branching direction at the branching point. As a result, the user can grasp by voice which direction the branch point should be advanced to reach the destination, so that it is not necessary to visually check the direction signboard 500 displayed on the display 214c, which is safer. Can be driven.

[4.4. Modification 4]
In the above embodiment, the direction sign 500 displays the past visited place (destination) included in the action area including the current position, but as shown in FIG. 14A, the current position is the action area. When included in A1, the direction of another action area A2 different from the action area A1 is displayed as shown in FIG. 14 (B), or the representative included in the action area A2 as shown in FIG. 14 (C). The position of the point (for example, the center point D (position of the center of gravity) of the action area A2) may be displayed. The representative point may be a point that any user included in the action area A2 has visited or searched for in the past, or may be a well-known spot in the action area A2.
