It is a figure which shows an example of the position of the selection part 304 in a modification.

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

As shown in FIG. 1, the display control device 1 includes reception means 111A, point image display means 111B, selection image display means 111C, and movement means 111D. Moreover, the display control device 1 may further include a determining means 111E. The display control device 1 is a device that moves together with a moving object.

The accepting unit 111A accepts an operator's operation on the operating 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, a ship, or the like, whose direction can be changed by a steering wheel. The operating unit is, for example, a pointing device such as a touch pad, joystick, cross key, pointing stick.

The point image display means 111B displays point images representing points on the map displayed on the screen. A point image is, for example, an icon representing a logo mark of a store (department store, convenience store, supermarket, restaurant, etc.) as the point.

The selection image display means 111C detects a preset action of the operator and displays on the screen a selection image used for selecting a point on the map. The operator's preset action includes, for example, an action of directing the face or line of sight to the displayed point image, an action of moving the point image, and the like.

The moving means 111D moves the screen position of the point image or the screen position of the selected image in accordance with the operation received by the receiving means 111A.

As a result, there is no need to remove the hand from the steering wheel to operate the operation unit, and the operator's safe driving is not hindered by excessively displaying selection images used for selecting points on the map.

Further, when the display control device 1 further includes a determination unit 111E, the determination unit 111E may determine selection candidate points as candidates for selection based on the positional relationship between the point image and the selection image. . 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 image is such that the point to be selected becomes the selection candidate point. By performing this operation on the selected operation unit, the point desired to be selected can be set as a selection candidate point. When the selection candidate point is determined, the display control device 1 accepts a further selection confirmation operation by the operator for making the selection candidate point the selection target, the selection candidate point is set as the selection target point. preferably determined.

Further, the moving means 111D may move and display the point image on the map together with the map in accordance with the operation received by the receiving means 111A, and may not move the selected image. In this case, the operator moves the map image together with the map so that the positional relationship between the point image representing the point to be selected and the selection image on the screen is such that the point to be selected becomes the selection candidate point. As a result, the point desired to be selected can be selected as a selection candidate point.

Furthermore, the selected image indicates a selected area that is a partial area on the screen, and the determination unit 111E determines that the point image is included in the selected area in response to the operation received by the receiving unit 111A. may be determined as a selection candidate point. Note that 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, or a predetermined ratio or more of the pixels representing the point image may be included in the selected area. It may be the case that In this case, the operator can set the point to be selected as a selection candidate point by performing an operation so that the point image representing the point to be selected on the screen is included in the selection area.

Furthermore, the selected image display means 111C may simultaneously display a selected image of a size that does not include a plurality of point images, according to the scale of the displayed map. As a result, it is possible to prevent a plurality of spot images from being included in the selection area at the same time and a plurality of spots to be selected candidate spots.

Furthermore, if the scale of the displayed map includes a plurality of spot images in the selection area at the same time, the spot image display means 111B changes the scale to a scale that does not include the plurality of spot images in the selection area at the same time. You can do it. As a result, it is possible to prevent a plurality of spot images from being included in the selection area at the same time and a plurality of spots from becoming selection candidate spots.

Furthermore, when a plurality of point images are included in the selected area according to the operation accepted by the accepting means 111A, the point image display means 111B displays each corresponding image corresponding to each point image included in the selected area. The corresponding image is displayed outside the selected area, and the moving means 111D moves the screen position of the corresponding image or the screen position of the selected area in accordance with a further operation by the operator (a further operation received by the receiving means 111A). When the corresponding image is included in the selection area, the determining means 111E may determine the point represented by the corresponding image as the selection candidate point. This makes it possible to narrow down the number of corresponding images corresponding to the point images included in the selection area.

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

Furthermore, the point represented by the point image may be a point associated with the operator. In this case, it is possible to present a point of interest to the operator. The point associated with the operator is determined by the display control device 1 or another device by a conventionally known method. Note that the point related to the operator may be a point on the route along which the operator moves. In addition, the point on the route is preferably a point on the left side of the route when left-hand traffic is set in advance as the road on which the mobile body travels, is set, it is preferably the point on the right side of the route.

Furthermore, the spot image display 111B may display a preset number of spot images. In this case, many spot images are displayed, and it is possible to prevent the operator from wondering which spot image to move in which direction in relation to the positional relationship with the selection unit. In addition, in order to appropriately move the point image representing the point you want to select as a selection target in terms of the positional relationship with the selected image (if a lot of point images are displayed, there is a risk that an unintended point may become a candidate point for selection. ) Since the operator does not have to concentrate on the operation, the concentration on driving can be maintained.

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

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

An embodiment will be described with reference to FIGS. 2 to 6. FIG. The embodiment described below is an embodiment in which the present invention is applied to an in-vehicle navigation device NV (an example of a "display control device"; hereinafter sometimes referred to as a "navigation device NV"). The navigation device NV is connected by wire or wirelessly to a touch pad T attached to a steering wheel (a steering wheel of an automobile in this embodiment) shown in FIG. That is, the touch pad T is one of the input devices of the in-vehicle navigation device NV.

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

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

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

The position where the frame image 302 is displayed 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 timing of displaying the frame image 301 may be the same as when the point icon 301 is displayed. It may be displayed when a hand motion (sometimes referred to as “related motion”) is detected. The actions of the driver preset in relation to the point icon 301 include, for example, an action of directing the face or line of sight to the displayed point icon 301, an action of moving the point icon 301 (for example, a touch pad operation of touching T). These actions are detected by an image captured by a camera installed inside the vehicle or by the touch pad T. FIG. By displaying the frame image 302 according to the driver's motion in this way, the frame image 302 is displayed only when the driver has an intention to select a location, such as when the driver is interested in the location represented by the location icon. can be made As a result, the unnecessary frame image 302 is not displayed on the screen 300, so the driver can concentrate on driving.

The frame image 302 serves as a target for moving the point icon 301. 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 indicated by the point icon 301. A selection candidate point that is a target candidate is determined (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 take any form as long as it represents the selected area. As shown in FIG. 3, when the selected area is represented by dotted lines or lines, the color and density of the lines do not matter (the lines may be translucent).

When the navigation device NV determines that the point icon 301A is included in the selection area represented by the frame image 302, as shown in FIG. 4, the display mode of the point icon 301 is changed. For example, the navigation device NV enlarges the point icon 301A, changes its color, or blinks it. This allows the driver to recognize that the point indicated by the point icon 301A has been determined as the selection candidate point. Then, when the navigation device NV receives a further selection confirmation operation (for example, an operation of tapping the touch pad T) by the driver on the touch pad T in a state where the selection candidate point is determined, the selection candidate point is selected. Determine the point of interest. Note that the navigation device NV may set the determined point to be selected as a destination or a stopping point to provide route guidance.

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

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 in which the navigation device NV is mounted. (Step S11). Next, the control unit 211 estimates the driver's destination or stopping point by the estimation function (step S12). Next, the control unit 211 narrows down the destination or stopover point estimated in the process of step S12 based on the above-described predetermined narrowing conditions, and sets it as a destination candidate or stopover candidate (step S13). Next, the control unit 211 displays on the map the point icons 301 respectively indicating the destination candidate site and the stopover candidate site (step S14). However, if there is a destination candidate site or a stopping candidate site outside the area displayed on the map screen, the point icon 301 is displayed when the map is scrolled and the area is entered on the screen. Alternatively, the scale of the map may be changed to display point icons 301 representing all candidate destinations or candidate stopping points.

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

Next, the control unit 211 performs a movement operation (tracing the touch pad T) to move the point icon 301 (and the map) within a predetermined time (for example, within 5 seconds) after the frame image 302 is displayed in the process of step S16. operation) is detected (step S17). If the control unit 211 determines that the movement operation for moving the point icon 301 (and the map) has not been 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 a movement operation for moving the location icon 301 (and the map) has been detected within the predetermined time (step S17: YES), the map and the location icon 301 are moved 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 one point icon 301 is not included in the selected area represented by the frame image 302 (step S20: NO), the process proceeds to step S17. On the other hand, when the control unit 211 determines that one point icon 301 is included in the selection area represented by the frame image 302 (step S20: YES), the point represented by the one point icon 301 is selected. A candidate point is determined, and the one point icon 301 is enlarged and displayed (an example of change in display mode) (step S21).

Next, the control unit 211 determines whether a selection confirmation operation (an operation of tapping the touch pad T) has been 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 confirming operation has not been detected within the predetermined time after the point icon 301 is enlarged and displayed (step S22: NO), the process proceeds to step S18. On the other hand, when the control unit 211 determines that the selection confirmation operation is detected within the predetermined time after the point icon 301 is enlarged and displayed (step S22: YES), the control unit 211 determines the selection candidate point as the selection point (step S23), the selected point determination process is terminated.

As described above, the navigation device NV (an example of the “display control device”) according to the present embodiment includes the control unit 211 (“reception means”, “point image display means”, “selected image display means”, “movement An example of a "means") accepts an operation of a driver (an example of an "operator") on a touch pad T (an example of an "operation unit") attached to a steering wheel H of an automobile (an example of a "moving body"), A map is displayed on the screen 300 of the display 214c, and a point icon 301 representing a point is displayed on the map. (an example of a "selection image used to select a point on the map") is further displayed on the screen 300, and the position of the point icon 301 on the screen 300 is moved according to the received operation.

Therefore, according to the navigation device NV according to the present embodiment, it is not necessary to remove the hand from the steering wheel H to operate the touch pad T, and the frame image 302 on the map is displayed more than necessary to ensure safe driving for the driver. It does not interfere with

Also, the control unit 211 (an example of a “determining unit”) determines selection candidate points as candidates for selection based on the positional relationship on the screen between the point icon 300 and the frame image 302 on the screen 300 . As a result, the driver can move the point icon so that the positional relationship between the point icon 301 representing the point desired to be selected and the frame image 302 on the screen 300 is such that the point desired to be selected becomes a selection candidate point. By performing this operation on the touch pad T attached to the steering wheel H, it is possible to set a point to be selected as a selection candidate point.

Also, the destination/drop-off point estimated in the process of step S12 (an example of the "point represented by the point image") is a point related to the driver based on the driver's past travel history or the like. This makes it possible to present points of interest to the driver. The stopping point may be a point on the route on which the driver travels, or if left-hand traffic is set in advance as the road on which the vehicle travels, it should be a point on the left side of the route. is preferred. As a result, it is possible to present a point at which the driver is likely to stop, which improves convenience for the driver.

Furthermore, the control unit 211 displays a point icon 301 on the map including the point where the vehicle is currently moving. In this case, the driver can select points near the current location as selection candidate points.

In this embodiment, the destination candidate sites/drop-off candidate sites narrowed down by the predetermined narrowing conditions in the process of step S13 are presented. , a preset number of point icons 301 may be displayed. In this case, many point icons 301 are displayed, and it is possible to prevent the driver from wondering which point icon 301 should be moved into the selection area. Also, in order to move the point icon 301 representing the point to be selected so as to be included in the selection area (if a lot of point icons 301 are displayed, the point represented by the unintended point icon 301 becomes the selection candidate point). Since the driver is not forced to concentrate on the operation for moving the point icon 301, the concentration on driving can be maintained.

Corresponding images 303A and 303B corresponding to the icons 301A and 302A are displayed outside the selection area, and the positions of the corresponding images 303A and 303B on the screen 300 are moved according to further operations 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. This makes it possible to narrow down the number of corresponding images 303A and 303B corresponding to the location icons 301A and 301B included in the selection area.

[4.5. Modification 5]
When the distance between the point icon 301 and the selection area on the screen 300 becomes smaller than the point at which the point icon 301 is displayed due to the received operation, the control unit 211 determines the point represented by the point icon as a selection candidate point. It is also possible to For example, as shown in FIG. 8, the distance between the point icon 301 and the selected area (the distance between the center (center of gravity) of the selected area and the center (center of gravity) of the point icon 301) Therefore, the point represented by the point image may be determined as the selection candidate point when the point image is closer than the predetermined ratio. Further, when the number of pixels corresponding to the distance between the point icon 301 and the selected area is equal to or less than a predetermined number of pixels, the point indicated by the point icon 301 may be determined as the selection candidate point. In other words, in this modification, selection candidate points can be determined even if the point icon 301 is not included in the selection area. In this case, the driver can make the point to be selected as a selection candidate point by performing an operation so as to reduce the distance between the point icon 301 representing the point to be selected on the screen 300 and the selection area.

[4.6. Modification 6]
In the above embodiment, the selection candidate points to be selected are determined based on the positional relationship between the selection area represented by the point icon 301 and the frame image 302 on the screen 300. 304 may be set. The selection portion 304 is formed by at least part of the edge of the screen 300 . In the example of FIG. 9, a linear selection section 304 is set on the upper right edge of the screen 300 . Note that one or more edges of the screen 300 may be set in the selection section 304 . In this case, if the control unit 211 determines that the point icon 301A is moved by the operation on the touch pad T and touches the selection unit 304, the point indicated by the point icon 301A is determined as the selection candidate point. . Further, as described in Modification 5 above, when it is determined that the point icon 301A has moved and the distance between the point icon 301A and the selection unit 304 has decreased, the point represented by the point icon 301A is determined as the selection candidate point. may be
