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

As shown in FIG. 1, the determination device 1 includes a reception unit 111A, a display control unit 111B, and a determination unit 111C. The determination device 1 is a device that moves together with the moving body.

The reception means 111A receives an operator's operation on the operation unit attached to the handle of the moving body. A moving body is, for example, a vehicle such as an automobile, a bicycle, an aircraft, or a ship that changes direction by a steering wheel. The operation unit is, for example, a pointing device such as a touch pad, a joystick, a cross key, or a pointing stick.

The display control means 111B displays a point image representing a point to be presented to the operator on a map on the screen, and is preset to a position on the screen or a screen of the point image according to the operation received by the reception means 111A. Move the position of the selection part. The point image is, for example, an icon representing the logo mark of the store when the point is a store (department store, convenience store, supermarket, restaurant, etc.). The selection unit may be, for example, a part of the screen, or at least a part of the edge of the screen (in this case, it may be a line instead of an area). When the selection unit is a partial area of the screen, for example, a frame image representing the partial area is displayed in order to inform the operator of the partial area. On the other hand, when the selection unit is the edge of the screen, in order to inform the operator of the selection unit, for example, an arrow image pointing to the selection unit is displayed, the position of the selection unit is guided by voice, or the determination is made. It is described in the instruction manual of the device 1.

The determination means 111C determines a selection candidate point as a candidate for selection based on the positional relationship between the point image and the selection unit.

As a result, the operator attaches an operation to the handle to move the point image or the selection part so that the positional relationship between the point image representing the point to be selected and the selection part becomes the selection candidate point. By performing the operation on the operation unit, the point to be selected can be set as the selection candidate point. That is, it is not necessary to take the hand off the steering wheel to operate the operation unit, and the operator can determine a selection candidate point that is a candidate for selection among the points displayed on the map. When the determination device 1 determines a selection candidate point and receives a further selection confirmation operation for selecting the selection candidate point by the operator, the determination device 1 determines the selection candidate point as the selection target point. It is preferable to do.

Further, the display control means 111B may move and display the point image on the map together with the map according to the operation received by the reception means 111A, and may not move the selection unit. In this case, the operator performs an operation of moving the map image together with the map so that the positional relationship between the point image representing the point to be selected as the selection target and the screen of the selection unit is the selection candidate point. As a result, the point to be selected can be set as the selection candidate point.

Further, the determination means 111C determines the point represented by the point image when the distance between the point image and the selection unit on the screen is shorter than the time when the point image is displayed in response to the operation received by the reception means 111A. It may be decided as a selection candidate point. In this case, the operator can set the point to be selected as the selection candidate point by operating so that the distance between the point image representing the point to be selected on the screen and the selection unit is shortened. The determination means 111C may determine, for example, a point represented by the point image as a selection candidate point when the distance between the point image and the selection unit is closer than a predetermined ratio from the time when the point image is displayed. Alternatively, when the number of pixels corresponding to the distance between the point image and the selection unit becomes a predetermined pixel or less, the point represented by the point image may be determined as the selection candidate point.

Furthermore, the selection unit may be a selection area which is a part of the screen, and when the determination means 111C includes a point image in the selection area according to the operation received by the reception means 111A, the selection unit may be a selection area. The point represented by the point image may be determined as a selection candidate point. When the point image is included in the selected area, the center (or the center of gravity) of the point image may be included in the selected area, and a predetermined ratio or more of pixels representing the point image is included. It may be the case. In this case, the operator may set the point to be selected as the selection candidate point by operating the point image representing the point to be selected on the screen so as to be included in the selection area which is the selection unit. it can.

Furthermore, when the selection unit is a selection area on the screen, the display control means 111B may simultaneously display a selection area having a size that does not include a plurality of point images according to the scale of the displayed map. Good. As a result, it is possible to prevent a plurality of point images from being included in the selection area at the same time and a plurality of points from becoming selection candidate points.

Furthermore, when the selection unit is a selection area on the screen, the display control means 111B sets the scale to a plurality of point images at the same time when a plurality of point images are included in the selection area at the same time at the scale of the displayed map. May be changed to a scale that is not included in the selection area. As a result, it is possible to prevent a plurality of point images from being included in the selected area at the same time and a plurality of points becoming selection candidate points.

Furthermore, when the selection unit is a selection area on the screen, the display control means 111B sets the selection area to the selection area when a plurality of point images are included in the selection area according to the operation received by the reception means 111A. Each corresponding image corresponding to each included point image is displayed outside the selected area, and the position of the corresponding image on the screen or the corresponding image is displayed according to a further operation by the operator (a further operation received by the reception means 111A). The position of the selected area may be moved, and when the corresponding image is included in the selected area, the determination means 111C may determine the point represented by the corresponding image as the selection candidate point. As a result, the number of corresponding images corresponding to the point images included in the selected area can be narrowed down.

Furthermore, if the operating unit is attached to any portion of the right half of the handle when the handle is not turned, the selection may be located in the area of the right half of the screen. As shown in FIG. 2, when the touch pad T which is an operation unit is provided on the handle H and the operator who is a driver operates the touch pad T with the finger of the right hand (for example, the thumb or the index finger), the right It is considered easy to move in the direction. Therefore, it is preferable that the selection unit is arranged in the right half area of the screen corresponding to the right direction, which is easy for the operator to operate, so that the operator can easily bring the point image closer to the selection unit. In this case, the operator can operate the operation unit to the right to set the point represented by the point image as a selection candidate point, which facilitates the operation. Similarly, if the operating unit is attached to any portion of the left half of the handle when the handle is not turned, the selection may be located in the area of the left half of the screen.

Furthermore, the point presented to the operator may be a point related to the operator. In this case, it is possible to present a point of interest to the operator. The point related to the operator is determined by the determination device 1 or another device by a conventionally known method. The point related to the operator may be a point on the route on which the operator moves. Further, when the left side traffic is set in advance as the road on which the moving body moves, the point on the route is preferably the left side point on the route, and the right side traffic is set in advance as the road on which the moving body moves. If so, it is preferably the point on the right side of the route.

Furthermore, the display control means 111B may display a preset number of point images. In this case, a large number of point images are displayed, and it is possible to prevent the operator from being confused as to which direction the point image should be moved in the positional relationship with the selection unit. In addition, in order to move the point image representing the point to be selected appropriately in the positional relationship with the selection unit (when many point images are displayed, an unintended point may become a selection candidate point. ) Since the operator is not concentrated on the operation, the concentration on the driving can be maintained.

Furthermore, the display control means 111B may display a point image on a map including a point where the moving body is moving. In this case, the operator can use a point near the current location as a selection candidate point.

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

Examples will be described with reference to FIGS. 2-. The examples described below are examples in which the present invention is applied to an in-vehicle navigation device NV (an example of a "determining device"; hereinafter, may be referred to as a "navigation device NV"). Further, the navigation device NV is connected to the touch pad T attached to the steering wheel shown in FIG. 2 (the steering wheel of the automobile in this embodiment) by wire or wirelessly, and accepts the driver's operation on the touch pad T. That is, the touch pad T is one of the input devices of the in-vehicle navigation device NV.

[1. Overview of navigation device NV]
The navigation device NV of this embodiment has an estimation function of estimating a destination, a stop, and a point of interest to which the driver of the vehicle is heading. The estimation function includes the driver's past driving history, the driver's movements taken by a camera installed in the vehicle interior, and the driver's biological information (body temperature, blood pressure, heart rate, etc.) acquired by a biosensor. Is used.

The navigation device NV narrows down a plurality of points estimated by the estimation function according to a predetermined narrowing condition, and displays a point icon representing the point on a map on the screen. The predetermined narrowing-down condition is, for example, a condition that the number of estimated points is the top n when arranged in an arbitrary arrangement order (for example, the order of the number of visits by the driver), and is equal to or higher than the predetermined order. There are conditions such as that.

The navigation device NV has a display function of displaying a map or the like on a display and a selection candidate point determination function. Specifically, the navigation device NV displays a map on the screen 300 of the display as shown in FIG. Further, the navigation device NV is a point estimated by the estimation function on the map, and the point icons 301A and 301B representing the points narrowed down by a predetermined narrowing condition (the point icons are collectively referred to as the point icon 301). In some cases), the frame image 302 is displayed. The frame image 302 is fixedly displayed on the screen 300 and does not move due to the driver's operation on the touch pad T. On the other hand, the point icon 301 moves together with the map by operating the touch pad T.

The position for displaying the frame image 302 may be any position within the screen 300. When the touch pad T is provided as shown in FIG. 2, it is preferable to arrange the frame image 302 in the right half area of the screen 300 so that the operator can easily operate the touch pad T. Further, the timing of displaying the frame image 301 may be the same as that of displaying the point icon 301, or after displaying the point icon 301, a preset operation related to the displayed point icon 301 may be performed. It may be displayed when a hand movement (sometimes referred to as "related movement") is detected. The preset driver's actions related to the point icon 301 include, for example, an action of directing a face or a line of sight to the displayed point icon 301, or an action of trying to move the point icon 301 (for example, a touch pad). Operation of touching T) and the like. These movements are detected by an image taken by a camera installed in the vehicle interior or by the touch pad T. By displaying the frame image 302 according to the driver's movement in this way, the frame image 302 is displayed only when the driver is interested in the point represented by the point icon and is willing to select the point. Can be made to. As a result, the driver can concentrate on driving because the unnecessary frame image 302 is not displayed on the screen 300.

The frame image 302 serves as a target when moving the point icon 301, and when the point icon 301 is included in the area on the screen 300 indicated by the frame image 302, the navigation device NV selects the point represented by the point icon 301. It is determined as a selection candidate point that is a target candidate (hereinafter, the area indicated by the frame image 302 (the area surrounded by the frame image 302) is referred to as a “selection area”).

The frame image 302 may be in any mode as long as it represents a selected area. When the selected area is represented by a dotted line or a line as shown in FIG. 3, the color and density of the line do not matter (the line may be translucent).

As shown in FIG. 4, the navigation device NV changes the display mode of the point icon 301 when it is determined that the point icon 301A is included in the selection area represented by the frame image 302. For example, the navigation device NV enlarges the point icon 301A, changes the color, and blinks it. As a result, the driver can recognize that the point represented by the point icon 301A has been determined as the selection candidate point. Then, when the navigation device NV accepts a further selection confirmation operation (for example, an operation of tapping the touch pad T) by the driver for the touch pad T in a state where the selection candidate point is determined, the selection candidate point is selected. Determine the target point. The navigation device NV may set the determined selection target point as a destination or a stop-by point to guide the route.

[3. Operation example of navigation device NV]
Next, an operation example of the selection point determination process by the navigation device NV will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart showing an example of the selection point determination process.

First, the control unit 211 of the navigation device NV causes the display 214c to display a map including the current position of the vehicle on which the navigation device NV is mounted. (Step S11). Next, the control unit 211 estimates the driver's destination or stop-by place by the estimation function (step S12). Next, the control unit 211 narrows down the destinations or stop-by points estimated in the process in step S12 based on the predetermined narrowing conditions described above, and sets them as destination candidate sites or stop-by candidate sites (step S13). Next, the control unit 211 displays the point icon 301 indicating the destination candidate site or the stop-by candidate site on the map (step S14). However, if there is a target candidate site or a stop-by candidate site outside the area displayed on the map screen, the point icon 301 is displayed when the map is scrolled and the area enters the screen. Alternatively, the scale of the map may be changed to display the point icon 301 representing all the destination candidate sites or stop-by candidate sites.

Next, the control unit 211 displays the point icon 301 in the process of step S14, and then within a predetermined time (for example, within 10 seconds), the related operation (driver's operation preset in relation to the point icon 301). ) Was detected (step S15). When the control unit 211 determines that the related operation is not detected within the predetermined time (step S15: NO), the control unit 211 shifts to the process in step S12. On the other hand, when the control unit 211 determines that the related operation is detected within the predetermined time (step S15: YES), the control unit 211 displays the frame image 302 on the display 214c (step S16).

Next, the control unit 211 traces the movement operation (touch pad T) to move the point icon 301 (and the map) within a predetermined time (for example, within 5 seconds) after displaying the frame image 302 in the process of step S16. It is determined whether or not the operation) is detected (step S17). When the control unit 211 determines that the movement operation for moving the point icon 301 (and the map) is not detected within the predetermined time (step S17: NO), the frame image 302 is hidden (step S18). The process proceeds to step S12. On the other hand, when the control unit 211 determines that the movement operation for moving the point icon 301 (and the map) is detected within the predetermined time (step S17: YES), the control unit 211 moves the map and the point icon 301 according to the movement operation. Display (step S19).

Next, the control unit 211 determines whether or not one point icon 301 is included in the selection area represented by the frame image 302 (step S20). When the control unit 211 determines that the one point icon 301 is not included in the selection area represented by the frame image 302 (step S20: NO), the control unit 211 proceeds to the process of step S17. On the other hand, when the control unit 211 determines that the one point icon 301 is included in the selection area represented by the frame image 302 (step S20: YES), the control unit 211 selects the point represented by the one point icon 301. A candidate point is determined, and the one point icon 301 is enlarged and displayed (an example of a change in the display mode) (step S21).

Next, the control unit 211 has detected whether or not the selection confirmation operation (operation of tapping the touch pad T) is detected within a predetermined time (for example, within 3 seconds) after the point icon 301 is enlarged and displayed in the process of step S21. (Step S22). When the control unit 211 determines that the selection confirmation operation has not been detected within a predetermined time after enlarging the point icon 301 (step S22: NO), the control unit 211 proceeds to the process of step S18. On the other hand, when the control unit 211 determines that the selection confirmation operation is detected within a predetermined time after enlarging the point icon 301 (step S22: YES), the control unit 211 determines the selection candidate point as the selection point (step). S23), the selection point determination process is completed.

As described above, in the navigation device NV (an example of the "decision device") according to the present embodiment, the control unit 211 (an example of the "reception means", the "display control means", and the "decision means") is an automobile (an example). The operation of the driver (an example of the "operator") on the touch pad T (an example of the "operation unit") attached to the handle H of the "moving body") is accepted and displayed on the screen 300 of the display 214c. A point icon 301 (an example of a "point image") representing a point to be presented to the driver is displayed on the map, and the position of the point icon 301 on the screen 300 is moved according to the received operation, and the point icon 301 on the screen 300 is displayed. Based on the positional relationship between and the selection area (an example of the "selection unit"), the selection candidate points that are candidates for selection are determined.

Therefore, according to the navigation device NV according to the present embodiment, the driver has a positional relationship between the point icon 301 representing the point to be selected and the screen 300 of the selection area, and the point to be selected is the selection candidate point. By operating the touch pad T in this way, a point to be selected can be set as a selection candidate point. That is, it is not necessary to take the hand off the handle H to operate the touch pad T, and the driver can determine a selection candidate point that is a candidate for selection among the points displayed on the map.

Further, the destination / stop-off point estimated by the process of step S12 is a point related to the driver based on the driver's past driving history and the like. This makes it possible to present points of interest to the driver. The stop-off point may be a point on the route on which the driver moves, and if left-hand traffic is set in advance as the road on which the vehicle moves, it should be a point on the left side of the route. Is preferable. As a result, it is possible to present a point where the driver can easily stop the vehicle, and the convenience of the driver is improved.

Further, the control unit 211 displays the point icon 301 on the map including the point where the vehicle is moving at that time. In this case, the driver can use a point near the current location as a candidate point for selection.

In this embodiment, the target candidate sites and stop-by candidate sites narrowed down by the predetermined narrowing conditions in the process of step S13 are presented, but the number of point icons 301 to be displayed is limited by the predetermined narrowing conditions. , A preset number of point icons 301 may be displayed. In this case, a large number of point icons 301 are displayed, and it is possible to prevent the driver from being confused as to which point icon 301 should be moved within the selected area. Further, in order to move the point icon 301 representing the point to be selected to be included in the selection area (when many point icons 301 are displayed, the point represented by the unintended point icon 301 becomes a selection candidate point. Since the driver does not concentrate on the operation for moving the point icon 301, it is possible to maintain the concentration on driving.

[4. Modification example]
Next, a modification 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 map and the point icon 301 are moved according to the operation on the touch pad T, but instead, the frame image 302 representing the selected area may be moved according to the operation on the touch pad T. Good.

[4.2. Modification 2]
The control unit 211 may display a selection area having a size that does not include a plurality of point icons 301 at the same time according to the scale of the displayed map. In this case, a plurality of point icons 301 are included in the selection area at the same time, and it is possible to prevent the plurality of points from becoming selection candidate points.

[4.3. Modification 3]
If the scale of the displayed map includes a plurality of point icons 301 at the same time in the selected area, the control unit 211 may change the scale to a scale in which the plurality of point icons 301 are not included in the selected area at the same time. Good. As a result, it is possible to prevent a plurality of point icons 301 from being included in the selection area at the same time and a plurality of points becoming selection candidate points.

[4.4. Modification 4]
As a result of moving the map and the point icon 301 according to the driver's operation, the control unit 211 includes a plurality of point icons 301 in the selected area, and as shown in FIG. 7, each point included in the selected area. The corresponding images 303A and 303B corresponding to the icons 301A and 302A are displayed outside the selected area, and the positions of the corresponding images 303A and 303B on the screen 300 are moved according to the further operation by the driver. When 303B is included in the selection area, the points represented by the included corresponding images 303A and 303B may be determined as selection candidate points. As a result, the number of corresponding images 303A and 303B corresponding to the point icons 301A and 301B included in the selection area can be narrowed down.

[4.5. Modification 5]
When the distance between the point icon 301 and the selection area on the screen 300 is shorter than the time when the point icon 301 is displayed by the received operation, the control unit 211 determines the point represented by the point icon as the selection candidate point. You may do it. For example, as shown in FIG. 8, the distance between the point icon 301 and the selected area (distance between the center (center of gravity) of the selected area and the center (center of gravity) of the point icon 301) is the time when the point icon 301 is initially displayed. Therefore, the point represented by the point image may be determined as the selection candidate point when the distance is closer than a predetermined ratio. Further, when the number of pixels corresponding to the distance between the point icon 301 and the selection area becomes a predetermined pixel or less, the point represented by the point icon 301 may be determined as the selection candidate point. That is, in the modified example, the selection candidate point can be determined even if the point icon 301 is not included in the selection area. In this case, the driver can set the point to be selected as the selection candidate point by operating so that the distance between the point icon 301 representing the point to be selected on the screen 300 and the selection area is shortened.

[4.6. Modification 6]
In the above embodiment, the selection candidate points to be the candidates for selection are determined based on the positional relationship between the point icon 301 and the selection area represented by the frame image 302 on the screen 300, but the selection is made instead of the selection area. The unit 304 may be set. The selection unit 304 is formed by at least a part of the edge of the screen 300. In the example of FIG. 9, a linear selection unit 304 is set on the upper right edge of the screen 300. In addition, one or a plurality of edges of the screen 300 may be set in the selection unit 304. In this case, when the control unit 211 determines that the point icon 301A moves by the operation of the touch pad T and touches the selection unit 304, the control unit 211 determines the point represented by the point icon 301A as the selection candidate point. .. Further, as described in the above modification 5, when it is determined that the point icon 301A moves and the distance between the point icon 301A and the selection unit 304 is shortened, the point represented by the point icon 301A is determined as the selection candidate point. May be.
