<Embodiment 1>
<Configuration>
With reference to FIG. 1, a conceptual overall configuration of the map display device according to the first exemplary embodiment will be described. In addition, although the use is not specifically limited about the map display apparatus, the following Embodiment 1 assumes and demonstrates the car navigation apparatus mounted in the vehicle as a moving body.

As shown in FIG. 1, the map display device receives input information according to the user's intention and displays the information. The input / display unit 1 and the input / display unit based on the input information received by the input / display unit 1. The first information storage unit 2 and the second information in which the control unit 4 that controls the display operation of the map drawing screen in 1 and the drawing object related to the map information to be referred to when the control unit 4 controls the operation are stored. And a storage unit 3.

The drawing object is an object such as a road line, characters, terrain, building, icon, background color (which may be transparent or translucent), attached information, and the like displayed on the drawing screen. The background color (background object) included in the drawing object is not limited to one that is uniformly colored, but may be one that has been subjected to gradation or that partially paints the drawing screen.

The input / display unit 1 is realized by, for example, a touch panel (display device with a touch panel), receives a user's touch (touch) on the display surface, and analyzes the user's intention from the touch position and operation on the display surface. As the user's intention, there are an operation on a displayed map, a route search instruction, an operation on a built-in audio device, and the like. The operations on the map include, for example, changing the scale, changing (scrolling) the position on the map to be displayed, searching for information around the current position, comparing the information, and the like.

The first information storage unit 2 and the second information storage unit 3 store drawing objects related to map information. Specifically, map data indicating terrain and the like, road data associated with a position on the map, building data (figure, shape), background color data, and the like are stored. Here, the building data is data indicating the three-dimensional shape, type, name, etc. of the building itself. Note that the information stored in the first information storage unit and the second information storage unit 3 is not limited to the drawing object, and various information to be displayed on the input / display unit 1 can be stored.

Specifically, the first information storage unit 2 and the second information storage unit 3 are realized by a hard disk drive, a memory card, a DVD, a Blu-ray disc, or the like.

The control unit 4 controls each functional unit provided in the map display device and causes the input / display unit 1 to display a map drawing screen. As shown in FIG. 1, the control unit 4 analyzes the input information from the user to form an extraction condition related to the drawing object that is necessary for creating the map drawing screen. For example, when the control unit 4 analyzes the input information and the user's intention is “search for information on surrounding highways”, the drawing object of the general road around the current position and the highway around the current position The conditions for extracting the drawing objects can be formed.

Further, the control unit 4 extracts drawing objects from the first information storage unit 2 and the second information storage unit 3 based on the extraction condition, and displays them on the input / display unit 1 in a desired manner. Specifically, the control unit 4 is realized by a computer (CPU) and its program.

FIG. 2 shows in detail the conceptual configuration of the control unit 4 in the configuration of the map display device shown in FIG.

An input analysis unit 401 that analyzes input information input from the input / display unit 1, a first information drawing unit 403, a second information drawing unit 405, and a combined drawing unit 407 based on the analysis result in the input analysis unit 401. The overall control unit 402 that controls and displays the map drawing screen on the input / display unit 1 and the first drawing object that is the drawing object stored in the first information storage unit 2 are extracted, and the first drawing screen holding unit 404 is extracted. In addition, a first information drawing unit 403 that draws a first drawing screen that is a map drawing screen by the first drawing object and a second drawing object that is a drawing object stored in the second information storage unit 3 are extracted, A second information drawing unit 405 for drawing a second drawing screen, which is a map drawing screen by the second drawing object, on the second drawing screen holding unit 406; A first drawing screen holding unit 404 that holds a drawing screen, a second drawing screen holding unit 406 that holds a second drawing screen, and a combined drawing screen obtained by combining the first drawing screen and the second drawing screen. A composite drawing unit 407 for drawing on the screen holding unit 408 and a composite drawing screen holding unit 408 for holding the composite drawing screen created by the composite drawing unit 407 are provided. The composite drawing screen held in the composite drawing screen holding unit 408 is displayed on the input / display unit 1.

The input analysis unit 401 analyzes input information according to the user's intention. That is, the drawing screen display content and conditions such as the position and operation of the user touching the display surface are analyzed, and an operation (device operation or the like) according to the user's intention is identified. Here, the user's touch panel operation includes a conventional simple touch operation (normal touch operation) in which an icon is touched, and a “gesture operation” with movement, that is, a “drag operation” or a “flying operation” described later. is there.

The overall control unit 402 specifies a necessary drawing object based on the analysis result, causes the first information drawing unit 403 to extract the first drawing object from the first information storage unit 2, and the second information drawing unit 405. Then, the second drawing object is extracted from the second information storage unit 3.

The first information drawing unit 403 forms a first drawing screen from the extracted first drawing object, and draws it on the first drawing screen holding unit 404 (memory unit). The drawing is realized by combining map data, road data, building data, and the like as map information in the extracted first drawing object.

The second information drawing unit 405 forms a second drawing screen from the extracted second drawing object, and draws it on the second drawing screen holding unit 406 (memory unit). The drawing is realized by combining map data, road data, building data, etc. as map information in the extracted second drawing object.

In the first information drawing unit 403 and the second information drawing unit 405, for example, information generated in the apparatus such as current position data of the vehicle, route data to the destination of the vehicle obtained by the route search operation, etc. These can be added to the map drawing screens (first drawing screen and second drawing screen) formed respectively and drawn on the corresponding drawing screen holding unit.

Further, the overall control unit 402 causes the composite drawing unit 407 to combine the first drawing screen held in the first drawing screen holding unit 404 and the second drawing screen held in the second drawing screen holding unit 406, thereby combining the drawing. Drawing is performed on the screen holding unit 408 (memory unit). The composite drawing screen is held in the composite drawing screen holding unit 408 (memory unit) and then displayed on the input / display unit 1.

The composite drawing unit 407 combines the first drawing screen and the second drawing screen so that the first drawing screen and the second drawing screen are displayed while being completely or partially overlapped with each other, thereby obtaining a combined drawing screen. By displaying the first drawing screen and the second drawing screen in an overlapping manner, the drawing object on the lower drawing screen is masked by the drawing object on the upper drawing screen (display of the drawing object on the upper drawing screen). The drawing object on the lower drawing screen is not displayed).

The overlapped part is usually in a state where you can see the drawing object on the map drawing screen that is overlaid, but by controlling the overlap, the drawing object on the map drawing screen displayed below Can see. Note that “upper and lower” here is the upper and lower in the normal direction of the display surface, and the upper side is “upper”, but actually the drawing screen data is conceptually superimposed. Is.

The first drawing screen and the second drawing screen to be synthesized can each have a first attention point and a second attention point set in advance.

Here, the first attention point and the second attention point are points that the user particularly pays attention on the drawing screen, and points to be compared when the user refers to both the first drawing screen and the second drawing screen. As subjectively defined. For example, points that are the purpose of creating the drawing screen, such as the current position of the vehicle in the map around the vehicle and the position of the destination in the map around the destination, can correspond.

The drawing objects displayed on each of the combined map drawing screens can have a predetermined relationship. The predetermined relationship includes, for example, a relationship based on whether the position of the vehicle on the map is coincident or close, a relationship on the moving route such as between the current position of the vehicle and the destination, and the current travel route of the vehicle And time relations such as past driving history.

The order of overlaying the map drawing screens can be determined for each combination of drawing objects, for example, in accordance with the user's intention. Further, the order of stacking can be changed at any time. At this time, it is also possible to make it easier to grasp by displaying in a vertical relationship (relationship between elevated road map and general road map, relationship between ground map and underground map) corresponding to the actual space layout. . A specific vertical relationship may be defined for a specific combination.

<Operation>
Next, an outline of the operation of the map display device according to the first embodiment will be described.

The map display device according to the present invention updates the drawing object of the map drawing screen overlaid by a predetermined operation (specifically, changes the transparency of the drawing object of the map drawing screen overlaid by the predetermined operation). By making the drawing objects on the lower map drawing screen visible, the relationship between the drawing objects on the plurality of map drawing screens can be easily grasped. In the operation, each functional unit is controlled by the control unit 4, particularly the overall control unit 402.

Also, in the first embodiment, a slide method is used as a specific method for updating the display position of the map drawing screen that is overlaid. The slide method is a first method in which the entire map drawing to be overlaid moves continuously as shown below, that is, the drawing object on the map drawing screen to be overlaid moves in the sliding direction in conjunction with the slide. Or, partially switch the display of the drawing object on the map drawing screen that is overlaid, and continuously change (increase or decrease) the display area of the map drawing screen that is overlaid, that is, overlay This is a second method in which only the area overlapping the drawing object on the lower map drawing screen is changed without changing the display position of the drawing object on the map drawing screen. It should be noted that how the display position of the map drawing screen that is overlaid is updated can be changed according to the user's operation mode on the display surface, the setting made in advance for the combination of maps, and the like.

Specific operation will be described with reference to FIG.

First, in step ST10, the map display device is turned on and an initial screen is displayed on the input / display unit 1. The initial screen can be set to a normal display mode, that is, a mode for accepting a normal touch operation.

Next, in step ST11, the input / display unit 1 performs a predetermined operation on the initial screen to shift to the slide display mode. Here, the slide display mode is a mode in which the display position of the map drawing screen overlaid can be updated using the above-described slide method.

The transition (transition to the slide display mode) can be performed by, for example, touch operation, button operation, icon operation, gesture operation, voice recognition, or the like on the initial screen.

When confirming whether or not the mode is changed to the slide display mode, it can be performed by referring to a parameter stored in the overall control unit 402 and storing the mode type. For example, whether or not the slide display mode is set can be determined based on whether the parameter value is larger or smaller than a predetermined threshold value. The value of the parameter may be changed according to an input from the user, or automatically changed according to preset conditions (including the vehicle state and the display state on the display surface). Also good. In addition, if the input / display unit 1 is set to display an icon or the like indicating whether or not the slide display mode is set, the mode can be easily confirmed, which is convenient.

When the mode is changed to the slide display mode, the slide distance X0 is set to 0 in step ST12.

Next, in step ST13, a first drawing screen and a second drawing screen are created. The creation is performed in the first information drawing unit 403 and the second information drawing unit 405 in accordance with the user input information as described above. The created first drawing screen is drawn and held in the first drawing screen holding unit 404, and the second drawing screen is drawn and held in the second drawing screen holding unit 406.

Next, in step ST14, it is detected whether or not a predetermined operation (slide operation) for updating the display position of the map drawing screen to be overlaid has been performed. The detection is performed by analyzing the gesture operation or the like in the input / display unit 1 in the input analysis unit 401. If a slide operation is detected, the process proceeds to step ST15. If a slide operation is not detected, the process proceeds to step ST16.

Next, in step ST15, the slide distance X0 is updated based on the slide operation.

Next, in step ST16, the drawing objects displayed on the first drawing screen and the second drawing screen are updated. The update includes the range around the vehicle displayed on the drawing screen, the map information displayed as a drawing object, etc. (road data, building data, data indicating traveling history, etc.) Update).

Next, in step ST17, the display position of the map drawing screen to be overlaid is determined according to the slide distance X0, and a composite drawing screen is created from the first drawing screen and the second drawing screen. The created composite drawing screen is drawn, that is, displayed on the input / display unit 1. Details will be described later.

Next, in step ST18, a predetermined operation for ending the slide display mode is detected. When the operation is detected, the process proceeds to step ST19, and when the operation is not detected, the process returns to step ST14. The slide display mode can be ended by, for example, touch operation, button operation, icon operation, gesture operation, voice recognition, or the like.

Next, in step ST19, the mode is changed to the normal display mode, and the process returns to step ST11.

Next, details of step ST16 will be described with reference to FIG. In step ST16, as described above, the range around the vehicle displayed on the drawing screen and the map information (road data, building data, and traveling history displayed as a drawing object) that change from moment to moment as the vehicle moves are shown. The drawing object displayed on the first drawing screen and the second drawing screen is updated (including data etc.), but the transparency of the second drawing object on the second drawing screen is changed according to a predetermined operation by the user. Is going.

As shown in FIG. 4, in step ST161, the input analysis unit 401 specifies a range specified (instructed) by a gesture operation by the user via the input / display unit 1 on the second drawing screen. For example, when there is an operation similar to the drag operation or the skip operation as described later with reference to FIG. 22, the range on the screen where the operation is performed is specified.

Next, in step ST162, the drawing object within the range designated by the user is specified. For example, an object in the specified area is specified as will be described later with reference to FIG.

Next, in step ST163, the specified drawing object is displayed in a semi-transparent display (semi-transparent display). Note that although semi-transparent display is used here, transmissive display (transparent display) may be used. That is, the overall control unit 402 controls the degree of masking of the first and second drawing objects according to the user's operation input received by the input / display unit 1, and the first control unit 402 changes the degree of masking. The second drawing object on the two drawing screen is controlled to be transparent or translucent (that is, the transparency is controlled).

Next, in step ST164, the second drawing screen holding unit 406 draws and holds the second drawing screen including the drawing object not subjected to the semi-transparent processing and the drawing object subjected to the semi-transparent processing.

Next, details of step ST17 will be described with reference to FIGS. In this step, a composite drawing screen is created, but as a sliding method of the map drawing screen superimposed on top, the entire map drawing screen overlaid is moved continuously, that is, the map drawing screen superimposed on top A case will be described in which a composite drawing screen is created using a first method (hereinafter referred to as board slide) in which the drawing object moves in the sliding direction in conjunction with the slide. In particular, a slide-out by a board slide, that is, a case where the map drawing screen superimposed on the map drawing screen is completely overlapped (overlapping state) and the method of moving out of the display surface is used is explained. To do. In the following, the map drawing screen superimposed on top is referred to as the second drawing screen, but it may be reversed.

First, in step ST411, the first drawing screen held in the first drawing screen holding unit 404 is drawn in the composite drawing screen holding unit 408.

Next, in step ST412, the overlapping position of the second drawing screen on the first drawing screen is determined according to the slide distance X0 updated by the slide operation. FIG. 6 and FIG. 7 schematically show a drawing screen composition method when the display positions of the drawing objects displayed on the drawing screen are different.

When the slide distance X0 is 0, the first drawing screen and the second drawing screen are completely overlapped, and the second drawing object is set to a position that masks all the first drawing objects. When the attention point is set, it is desirable that the first attention point on the first drawing screen and the second attention point on the second drawing screen overlap with each other on the display surface. That is, when a map around the vehicle is shown on the first drawing screen and the second drawing screen, it is desirable that the current position of the vehicle on each drawing screen is the same (in this case, The position of the first attention point and the second attention point on the map is also common).

When the slide distance X0 is updated to a value other than 0, the overlapping position of the second drawing screen on the first drawing screen according to the position where the user touches the display surface in the gesture operation, for example, and the slide distance X0 based on the operation To decide.

For example, the distance (slide distance X0 in FIGS. 6 and 7) that the user touches and moves the display surface is set as an offset to the overlap start position where the screen edge of the second drawing screen is located. Like the operation, an operation in which a drawing screen superimposed on a predetermined touch operation (for example, moving a finger at a predetermined speed or less in a certain direction on the display surface) moves is called a drag operation, The mode in which the operation is performed is called a drag mode.

Further, for example, the distance that the user touches and moves the display surface (slide distance X0 in FIGS. 6 and 7) is set as an offset to the overlap start position where the screen edge of the second drawing screen is located, and the user is placed on the display surface. At the same time as the touch operation is finished, the original overlap position before the touch and movement is restored. Like the operation, the drawing screen overlaid is moved following a predetermined touch operation (for example, moving a finger in a certain direction on the display surface at a predetermined speed or less), and the original operation is performed simultaneously with the end of the touch operation. The operation for returning to the overlapping position is called a shutter operation, and the mode for performing the operation is called a shutter mode. The shutter operation and the drag operation can be distinguished by the number of fingers touching the display surface, for example.

Further, for example, when the user touches the display surface and performs an operation (flicking operation) such that the playing card flies, an amount that increases with time (the slide distance X0 in FIGS. 6 and 7 increases with time). As the offset, the overlap start position of the second drawing screen is set. Like this operation, the drawing screen that is overlaid in the direction specified by the predetermined touch operation is moved, and thereafter the operation to move according to the predetermined inertia is called a skip operation, and the mode for performing the operation is called the skip mode. .

In the skip mode, for example, the skip operation is determined under the following conditions and combinations. (A) After touching the touch panel, when a finger is quickly moved in a certain direction on the display surface at a predetermined speed or higher, (b) after pressing the touch panel, a predetermined predetermined direction on the display surface When moving the finger quickly by lowering the pressure at or above the speed, (c) touching the touch panel, then quickly moving the finger at a predetermined speed or higher in a certain direction on the display surface, and releasing the finger slightly from the touch panel (However, in this case, a touch pal that recognizes a three-dimensional position is necessary).

Note that the speed set as the predetermined speed in (a) to (c) may be different for each condition.

Next, in step ST413, the second drawing screen is overlaid and drawn (data is overwritten) in accordance with the overlapping position, specifically the overlapping start position. For example, when sliding out to the right side of the display surface, drawing is performed so that the left end of the second drawing screen matches the overlap start position.

The portion that does not overlap the first drawing screen (P2 in FIGS. 6 and 7) is not displayed on the display surface. In this state, the first drawing object of the first drawing screen having a width of the slide distance X0 where the second drawing screen does not overlap, and the second drawing object of the second drawing screen (width D1 from the left end of the second drawing screen) P1) in FIGS. 6 and 7 is displayed on the display surface. Here, the width D1 in FIGS. 6 and 7 is a length corresponding to the width of the second drawing screen displayed on the composite drawing screen.

8 By sequentially creating the composite drawing screen as described above, the operation shown in FIG. 8 (slide out by board slide) becomes possible. In FIG. 8, the drawing object a, the drawing object b, the drawing object c, and the second background drawing object are drawn on the first drawing screen on which the drawing object A, the drawing object B, the drawing object C, and the first background drawing object are drawn. The second drawing screen is overlapped. Suppose that the first point of interest on the first drawing screen is the drawing object A, and the second point of interest on the second drawing screen is the drawing object a. Each of the first background drawing object and the second background drawing object is, for example, a rectangular object painted in cream color with the same size as the first drawing screen and the second drawing screen. On the second drawing screen, a drawing object a, a drawing object b, and a drawing object c are drawn on the second background drawing object.

In FIG. 8, (1a), (2a), and (3a) are schematic views of the lower first drawing screen and the upper second drawing screen as viewed from the side, (1b) (2b) (3b) ) Is a schematic view of the first drawing screen and the second drawing screen as viewed from above.

Touch the input / display unit 1 with the user's finger and move it to the right in the figure (drag operation). Then, the overlapping start position of the upper second drawing screen is sequentially updated (1a → 2a → 3a, or 1b → 2b → 3b), and the entire second drawing screen is displayed as if it is slid on the board ( Board slide).

That is, when the above-described slide operation is performed, the drawing object a, the drawing object b, and the drawing object c in FIG. 8 move to the right as if they are on the board together with the second background drawing object.

In the states (1a) and (1b), the first drawing screen and the second drawing screen are completely overlapped, and the drawing object A, the drawing object B, and the drawing object C are masked by the second background drawing object. For example, when a map around the vehicle is shown on the first drawing screen and the second drawing screen, the current positions of the vehicles on the respective drawing screens match (that is, the first attention point and the second attention point). The point on the map matches the point). When the second drawing screen is a screen that is smaller than the first drawing screen, it is only necessary that the second drawing screen overlaps an area on the first drawing screen corresponding to the size of the second drawing screen.

In the states (2a) and (2b), the drawing object a and the drawing object b are displayed on the display surface, but the rightmost drawing object c deviates from the display surface of the input / display unit 1 and is not displayed. . On the other hand, although the drawing object A is displayed, the drawing object B is masked and hidden by the second background drawing object, and the drawing object C is masked and hidden by the second background drawing object. At this time, the relative positional relationship between the upper second drawing screen and the lower first drawing screen changes as needed.

In the states (3a) and (3b), the upper second drawing screen moves further to the right, and the drawing object b is also removed from the display surface of the input / display unit 1 and is not displayed. On the other hand, the drawing object A and the drawing object B are displayed, but the drawing object C is masked by the second background drawing object and is not displayed. At this time, the relative positional relationship between the upper second drawing screen and the lower first drawing screen changes as needed.

Next, referring to FIGS. 9 to 11, from the slide-in by the board slide, that is, from the state in which the map drawing screens do not overlap (totally shifted state), the map drawing screen that overlaps moves from the outside of the display surface and overlaps, A case will be described in which a composite drawing screen is created using a method in which map drawing screens overlap each other (full overlap state).

First, in step ST431, the first drawing screen held in the first drawing screen holding unit 404 is drawn in the composite drawing screen holding unit 408.

Next, in step ST432, the overlapping position of the second drawing screen on the first drawing screen is determined according to the slide distance X0 updated by the sliding operation. FIG. 10 and FIG. 11 schematically show a drawing screen composition method when the display positions of the drawing objects displayed on the drawing screen are different.

When the slide distance X0 is 0, for example, the position is set such that the second drawing screen is completely out of the display surface.

When the slide distance X0 is updated to a value other than 0, the overlapping position of the second drawing screen on the first drawing screen according to the position where the user touches the display surface in the gesture operation, for example, and the slide distance X0 based on the operation To decide.

When the attention point is set, the update of the slide distance X0 causes the first drawing point on the first drawing screen to approach the second attention point on the second drawing screen. It is desirable to determine the overlapping position on the first drawing screen.

Next, in step ST433, the second drawing screen is drawn in an overlapping manner according to the overlapping position, specifically, the overlapping start position. For example, when sliding in from the left side of the display surface, the drawing is performed so that the right end of the second drawing screen matches the overlap start position.

The portion that does not overlap the first drawing screen (P1 in FIGS. 10 and 11) is not displayed on the display surface. In this state, the first drawing object of the first drawing screen having a width D1 with which the second drawing screen does not overlap, and the second drawing object of the second drawing screen (slid distance X0 from the right end of the second drawing screen) (FIG. 10). And P2) in FIG. 11 are displayed on the display surface.

Next, referring to FIGS. 12 to 14, the slide-in by the board slide from the side opposite to the case in FIGS. 9 to 11 will be described.

First, in step ST441, the first drawing screen held in the first drawing screen holding unit 404 is drawn in the composite drawing screen holding unit 408.

Next, in step ST442, the overlapping position of the second drawing screen on the first drawing screen is determined according to the slide distance X0 updated by the sliding operation. FIG. 13 and FIG. 14 schematically show a drawing screen composition method when the display positions of the drawing objects displayed on the drawing screen are different.

When the slide distance X0 is 0, for example, the position is set such that the second drawing screen is completely out of the display surface. However, it is outside the display surface on the opposite side (right side) from the case in FIGS.

When the slide distance X0 is updated to a value other than 0, the overlapping position of the second drawing screen on the first drawing screen according to the position where the user touches the display surface in the gesture operation, for example, and the slide distance X0 based on the operation To decide.

Next, in step ST443, the second drawing screen is drawn in an overlapping manner according to the overlapping position, specifically, the overlapping start position. For example, when sliding in from the right side of the display surface, the drawing is performed so that the left end of the second drawing screen coincides with the overlap start position.

The portion that does not overlap the first drawing screen (P2 in FIGS. 13 and 14) is not displayed on the display surface. In this state, the first drawing object of the first drawing screen having the width D1 that does not overlap the second drawing screen and the second drawing object of the second drawing screen (slid distance X0 from the left end of the second drawing screen) (FIG. 13). And P1) in FIG. 14 are displayed on the display surface. In the case of FIG. 10 and FIG. 11, the left and right arrangement relations are switched and displayed.

In the slide method described above, the drawing screen superimposed on the top moves, and the range in which the lower drawing screen can be seen changes according to the movement. The sliding method is not limited to the above case, and various variations such as the direction of sliding and the movement of the drawing screen when sliding are conceivable.

Further, details of step ST17 in the case of another sliding method will be described with reference to FIGS. In this step, a composite drawing screen is created. As a slide method for the map drawing screen that is overlaid, the display of the drawing object on the map drawing screen that is overlaid is partially switched, and the map drawing screen that is overlaid is displayed. The display area is continuously changed (increased or decreased), that is, only the area that overlaps the drawing object on the lower map drawing screen without changing the display position of the drawing object on the upper map drawing screen. A case will be described in which a composite drawing screen is created by using a second method (hereinafter referred to as curtain slide) for changing. In particular, from the slide-out by the curtain slide, that is, from the state in which the map drawing screens overlap each other (full stacking state), the map drawing screen superimposed on top is continuously removed while maintaining its position, and the map drawing below The case where the method of becoming a display area where the screen is displayed is described. In the following, the map drawing screen superimposed on top is referred to as the second drawing screen, but it may be reversed.

First, in step ST421, the first drawing screen held in the first drawing screen holding unit 404 is drawn in the composite drawing screen holding unit 408.

Next, in step ST422, the overlapping position of the second drawing screen on the first drawing screen is determined according to the slide distance X0 updated by the sliding operation.

When the slide distance X0 is 0, the first drawing screen and the second drawing screen are completely overlapped, and the second drawing object is set to a position that masks all the first drawing objects. When the attention point is set, it is desirable that the first attention point on the first drawing screen and the second attention point on the second drawing screen overlap with each other on the display surface. That is, when a map around the vehicle is shown on the first drawing screen and the second drawing screen, it is desirable that the current position of the vehicle on each drawing screen match.

When the slide distance X0 is updated to a value other than 0, the overlapping position of the second drawing screen on the first drawing screen according to the position where the user touches the display surface in the gesture operation, for example, and the slide distance X0 based on the operation To decide.

For example, the distance (slide distance X0 in FIG. 16) moved by the user touching the display surface is set as an offset to the overlap start position where the screen edge to be removed of the second drawing screen is located. Like the operation, an operation in which a drawing screen superimposed on a predetermined touch operation (for example, moving a finger at a predetermined speed or less in a certain direction on the display surface) moves is called a drag operation, The mode in which the operation is performed is called a drag mode.

In addition, for example, an operation in which the user touches the display surface by setting the distance (the slide distance X0 in FIG. 16) moved by touching the display surface as an offset to the overlap start position where the screen edge of the second drawing screen is located. At the same time as ending, return to the original overlapping position before touching and moving. Like the operation, the drawing screen overlaid is moved following a predetermined touch operation (for example, moving a finger in a certain direction on the display surface at a predetermined speed or less), and the original operation is performed simultaneously with the end of the touch operation. The operation for returning to the overlapping position is called a shutter operation, and the mode for performing the operation is called a shutter mode. The shutter operation and the drag operation can be distinguished by the number of fingers touching the display surface, for example.

Further, for example, when the user touches the display surface and performs an operation (flicking operation) such that the playing card flies, an amount that increases with time (the slide distance X0 in FIG. 16 increases with time) is used as an offset. The overlapping start position of the second drawing screen is set. Like this operation, the drawing screen that is overlaid in the direction specified by the predetermined touch operation is moved, and thereafter the operation to move according to the predetermined inertia is called a skip operation, and the mode for performing the operation is called the skip mode. .

Next, in step ST423, the second drawing screen is drawn in an overlapping manner according to the overlapping position, specifically, the overlapping start position. For example, when sliding out to the right side of the display surface, drawing is performed so that the left end of the second drawing screen to be removed matches the overlap start position. That is, the position of the second drawing screen that matches the overlap start position is a position that is offset from the left end of the screen by the slide distance X0 on the second drawing screen.

The part removed from the first drawing screen (P1 in FIG. 16) is not displayed on the display surface. In this state, the first drawing object of the first drawing screen having a width of the slide distance X0 where the second drawing screen does not overlap, and the second drawing object of the second drawing screen (width D1 from the right end of the second drawing screen) P2) in FIG. 16 is displayed on the display surface.

By sequentially creating the composite drawing screen as described above, the operation shown in FIG. 17 (slide out by curtain slide) becomes possible. In FIG. 17, the second drawing screen on which the drawing object a, the drawing object b, and the drawing object c are drawn is superimposed on the first drawing screen on which the drawing object A, the drawing object B, and the drawing object C are drawn. Suppose that the first point of interest on the first drawing screen is a drawing object B, and the second point of interest on the second drawing screen is a drawing object b.

In FIG. 17, (1a), (2a), and (3a) are schematic views of the lower first drawing screen and the upper second drawing screen as viewed from the side, and (1b) (2b) (3b) ) Is a schematic view of the first drawing screen and the second drawing screen as viewed from above.

Touch the input / display unit 1 with the user's finger and move it to the right in the figure (drag operation). Then, the overlapping start position of the upper second drawing screen is sequentially updated (1a → 2a → 3a or 1b → 2b → 3b), and the second drawing screen continuously draws the curtain while maintaining the display position. It is displayed by sliding (curtain slide).

In the states (1a) and (1b), the first drawing screen and the second drawing screen are completely overlapped, and the drawing object A, the drawing object B, and the drawing object C are masked by the second background drawing object. For example, when a map around the vehicle is shown on the first drawing screen and the second drawing screen, the current positions of the vehicles on the respective drawing screens match (that is, the first attention point and the second attention point). The point on the map matches the point). When the second drawing screen is a screen that is smaller than the first drawing screen, it is only necessary that the second drawing screen overlaps an area on the first drawing screen corresponding to the size of the second drawing screen.

In the states (2a) and (2b), the drawing object b and the drawing object c are displayed on the display surface, but the leftmost drawing object a is removed from the display surface of the input / display unit 1 and displayed. Disappear. On the other hand, although the drawing object A is displayed, the drawing object B is masked and hidden by the second background drawing object, and the drawing object C is masked and hidden by the second background drawing object. At this time, the relative positional relationship between the upper second drawing screen and the lower first drawing screen is maintained. That is, the first attention point and the second attention point always coincide on the display surface.

In the states (3a) and (3b), the upper second drawing screen is further removed to the right, and the drawing object b is also removed from the display surface of the input / display unit 1 and is not displayed. On the other hand, the drawing object A and the drawing object B are displayed, but the drawing object C is masked by the second background drawing object and is not displayed. At this time, the relative positional relationship between the upper second drawing screen and the lower first drawing screen is maintained.

Further, the second background drawing object has been described as a single cream color. For example, in FIG. 17, when the gradation is applied so that the vicinity of the drawing object a is cream and the drawing object c is pink. , (1a), (2a), (3a), the drawing background color in the vicinity of the drawing object c is a color close to the same pink.

In the above description, the slide-out by the curtain slide has been described, but the slide-in by the curtain slide, that is, the map drawing screen superimposed on the map drawing screen maintains its position from the state in which the map drawing screen does not overlap (totally shifted state). However, the operation in the case where it appears continuously and becomes a display area where the map drawing screen above is displayed is the reverse direction of FIG. 17 ((3a, 3b) → (2a, 2b) in FIG. 17 → ( 1a, 1b)).

In addition, the slide method described above changes the range in which the lower map drawing screen can be seen by changing the display area continuously while maintaining the display position of the map drawing screen overlaid. Is. The slide method is not limited to the above case, and various variations such as the direction in which the fluctuation progresses (spreading around the touch position, etc.), the display method of the map drawing screen at the time of switching the display (flashing or fading), etc. .

In addition, the slide method described above allows the user to perform a slide operation no matter where the user touches the area where the second drawing screen is displayed. However, the second drawing screen that accepts the slide operation is displayed. The range may be limited. For example, it may be configured to receive a slide on the second drawing screen when a gesture indicating a slide is performed near the boundary where the second drawing screen is displayed.

Also, an area on the second drawing screen that accepts a slide operation may be displayed with an icon or the like. In this case, normal operation transitions by drag operation, skip operation, and simple touch operation can be received side by side, and a user-friendly device can be provided.

Further, in the above, the second background drawing object is not limited to the rectangular shape with the cream-colored rectangular object having the same size as the drawing screen, and the bottom may be a trapezoidal shape, an elliptical shape, or a perforated object. The color may not be a single color but may have gradations and patterns, and can provide a display with a good design for the user.

In the above description, the first drawing object and the second drawing object have been described as being stored in the first information storage unit 2 and the second information storage unit 3, respectively. The drawing object may be generated. For example, the vehicle position mark or the like may be created by the overall control unit 402 by a program. In addition, the overall control unit 402 may generate both or one of the background drawing objects by software processing.

In the above description, the method of rendering the background drawing object, which is a rectangular drawing object, on the drawing screen has been described. However, the method of generating the background drawing object is not limited to this method. For example, the drawing screen itself is the background drawing object. In the case of having a function of generating a background color corresponding to, the overall control unit 402 may set the background colors of the first drawing screen holding unit 404 and the second drawing screen holding unit 406 by software processing.

In addition, when the composite drawing unit 407 inputs and generates the background color settings of the first drawing screen and the second drawing screen in terms of hardware structure or software processing, the overall control unit 402 performs the respective background colors by software processing. May be set.

The drawing object referred to in the present invention is a concept including a display object that is finally displayed on the input / display unit 1 by the above-described software processing.

Next, a specific example of the operation using the above sliding method will be described.

18 to 22 are diagrams showing specific examples of the operation of the map display device according to the first embodiment. 18 to 22 show an operation of changing the transparency of the second drawing object on the second drawing screen after the second drawing screen is slid into the first drawing screen by the curtain slide from the completely displaced state.

As a premise of the operation, the first information drawing unit 403 forms the first drawing screen shown in FIG. 18A and draws it on the first drawing screen holding unit 404. On the first drawing screen, a map including the car navigation guidance route and the vehicle position is displayed as the first drawing object. The second information drawing unit 406 forms the second drawing screen shown in FIG. 18B and draws it on the second drawing screen holding unit 406. On the second drawing screen, a drawing object including three-dimensional building data associated with the position of the first drawing object on the map is displayed as the second drawing object. The second background drawing object is transparent. Or it may not exist.

As shown in FIG. 19A, only the first drawing screen is displayed on the display surface of the input / display unit 1. An icon labeled “3D” is displayed at the upper left of the first drawing screen. The icon is used to display a second drawing screen with a three-dimensional building as a second drawing object when selected. The icon can be displayed at any location on the first drawing screen.

In the state of FIG. 19A, when the user selects an icon (for example, presses the icon display portion with a finger), the slide operation area is displayed at the left end of the first drawing screen as shown in FIG. Is done.

In the state of FIG. 19B, when the user drags the slide operation area in the right direction of the first drawing screen (for example, the user touches the slide operation area with a finger and drags it), FIG. ), (D), the second drawing screen is displayed by gradually sliding in from the left end of the first drawing screen. At this time, the background of the second drawing screen is displayed in a translucent manner so that it can be distinguished from the first drawing screen. Note that the second drawing screen may not be translucent and may be displayed so as to be distinguishable from the first drawing screen. That is, it is only necessary to display a slidable screen (here, the second drawing screen) so that it can be distinguished.

As shown in FIGS. 19 (c) and 19 (d), when the drag operation is stopped halfway and the user releases his / her finger from the display surface, as shown in FIG. 20 (a), the slide is performed at the position where the drag operation is stopped. The operation area is fixed. That is, the display area of the second drawing screen that is slid in by the curtain slide is determined (the area that the second drawing object of the second drawing screen masks the first drawing object of the first drawing screen). At this time, the background of the second drawing screen remains translucent. In the state of FIG. 20A, when the user drags the slide operation area again, the second drawing screen can be slid in or out by curtain slide according to the drag operation.

In FIG. 20A, when the drag operation is stopped, the slide operation area is fixed and displayed at the stopped position, but as shown in FIG. 20B, an icon is displayed instead of the slide operation area. You may let them. At this time, the background of the second drawing screen may be transparent. When the icon is selected in the state of FIG. 20B, the display returns to the display shown in FIG. 20A, and the user can restart the drag operation.

When the second drawing screen is slid to the right end of the first drawing screen by the drag operation, the entire second drawing screen is displayed so as to overlap the entire first drawing screen as shown in FIG. Overlapping state). That is, all the second drawing objects on the second drawing screen are in a state of masking the first drawing object on the first drawing screen. At this time, a slide operation area is displayed at the right end of the display screen.

In FIG. 21A, the slide operation area is displayed at the right end of the display screen. However, as shown in FIG. 21B, a predetermined portion of the display screen (FIG. 21B shows the display screen). An icon may be displayed in the lower right). That is, in the state of FIGS. 21A and 21B, the user may be able to recognize that there is a slidable second drawing screen. When the user selects an icon in the state of FIG. 21B, a slide operation area as shown in FIG. 21A may be displayed.

Further, in the state of FIG. 21A, when the user drags the slide operation area to the left of the display screen, the second drawing screen can be slid out by the curtain slide according to the drag operation. Specifically, the second drawing screen can be slid out in the order of FIG. 21 (a) → FIG. 20 (a) → FIG. 19 (d) → FIG. 19 (c) → FIG. 19 (b).

Further, in the state of FIG. 21A, when the user performs an operation of skipping the slide operation area in the left direction of the display screen, the state of FIG. 21A (full overlap state) to the state of FIG. The display may be changed at once.

As shown in FIG. 21A, when the user stops the drag operation and lifts the finger away from the display surface, the user draws the second drawing object on the second drawing screen as shown in FIGS. 22A and 22B. You will be able to change the transparency.

As shown in FIG. 22 (a), when the destination of the guide route is blocked by the front buildings 9 and 10 and cannot be seen, the user performs, for example, the same operation (gesture operation) as the drag operation or the fly operation described above. When it is performed on the buildings 9 and 10 (rightward in FIG. 22A), as shown in FIG. 22B, the buildings 9 and 10 are displayed translucently. The buildings 9 and 10 may be transparently displayed. Further, for example, when the user performs an operation similar to the drag operation or the fly operation described above on the buildings 9 and 10 in the opposite direction (leftward in the state of FIG. 22B), the buildings 9 and 10 are performed. The semi-transparent display may be canceled.

From the above, the user can easily recognize the guide route hidden in the buildings 9 and 10 that could not be recognized in FIG. 22A, and can know the route situation after turning right at the intersection, for example.

Note that the transparency of the second drawing object (the building in the above) on the second drawing screen is changed even when the drag operation is stopped halfway as shown in FIGS. 20 (a) and 20 (b). Can do.

In the state shown in FIG. 22A or 22B, when the user drags the slide operation area to the left of the display screen, the second drawing screen can be slid out by the curtain slide according to the drag operation. Specifically, the second drawing screen may be slid out in the order of FIG. 22 (a) or (b) → FIG. 20 (a) → FIG. 19 (d) → FIG. 19 (c) → FIG. 19 (b). it can.

Also, in the state of FIG. 22 (a) or (b), when the user operates the slide operation area to the left of the display screen, the state from FIG. 20 (a) or (b) to the state of FIG. 19 (b). You may make it slide out the 2nd drawing screen at a stretch so that it may become.

In FIG. 18, the second drawing screen is slid in by the curtain slide. However, the second drawing screen may be slid in by the board slide. In this case, after the second drawing screen is slid in from the state shown in FIG. 19B (full shift state) to the state shown in FIG. 21A (full overlap state), it is shown in FIGS. The transparency of the second drawing object (the building in the above) on the second drawing screen is changed. Note that the transparency of the second drawing object (the building in the above) on the second drawing screen may be changed in a state where it is stopped during the slide-in (the state shown in FIG. 20A). In this case, during the slide-in, the first drawing object on the first drawing screen hidden by the second drawing object on the second drawing screen can be visually recognized.

In the above description, the second drawing screen is slid in and superimposed on the first drawing screen. However, for example, a planar map (third drawing object) and a three-dimensional object are displayed on one drawing screen (first drawing screen). A shape building (fourth drawing object) may be displayed, and a three-dimensional building may be designated to change the transparency.

23 and 24 are diagrams showing another specific example of the operation of the map display device according to the first embodiment. In FIGS. 23 and 24, the hue of the drawing object designated by the user is changed. That is, the hue of the drawing object is changed in step ST163 in FIG. Note that the process for the second drawing screen is performed in step ST16 of FIG.

In FIG. 23A, the second drawing screen is superimposed on the first drawing screen. On the first drawing screen, a map such as a car navigation route (guide route) and the vehicle position is displayed as a first drawing object. In addition, on the second drawing screen, a drawing object including POI (Point Of Interest) data, which is a drawing object related to feature information associated with the position of the first drawing object on the map, is displayed as the second drawing object. Has been. It is assumed that the second drawing object is transparent except for the portion where the POI is displayed. That is, the second background drawing object is transparent. Or it may not exist. As the method for displaying the second drawing screen so as to overlap the first drawing screen, the methods described in FIGS. 18 to 22 can be used.

In the state of FIG. 23A, when the user performs, for example, the same operation (gesture operation) as the drag operation or the skip operation described above once in the right direction with respect to the second drawing screen, the drawing on the second drawing screen is performed. An object (POI in FIG. 19) is specified, and the hue of the POI becomes dark as shown in FIG.

Further, in the state of FIG. 23B, when the user performs, for example, the same operation as the drag operation or the skip operation described above once in the right direction with respect to the second drawing screen, as shown in FIG. In addition, the hue of POI becomes darker.

Also, in the state of FIG. 24C (corresponding to FIG. 23C), when the user performs, for example, the same operation as the drag operation or the skip operation described above once in the left direction with respect to the second drawing screen. As shown in FIG. 24B (corresponding to FIG. 23B), the hue of the POI becomes brighter.

Also, in the state of FIG. 24B (corresponding to FIG. 23B), when the user performs, for example, the same operation as the above-described drag operation or skip operation once in the left direction with respect to the second drawing screen. 24A (corresponding to FIG. 23A), the hue of the POI becomes even brighter.

As described above, the user can arbitrarily change the hue of the drawing object (POI in FIGS. 23 and 24) in the second drawing screen, and the display can be easily displayed according to the purpose.

As described above, according to the first embodiment, when a plurality of map drawing screens are displayed on the display surface, the relationship between the drawing objects on each map drawing screen can be easily grasped, and the user's operation It becomes possible to improve the property.

In the first embodiment, the transmittance (transparency) for the second drawing object on the second drawing screen performed in step ST163 in FIG. 4 is a predetermined value. A means for setting an arbitrary transmittance may be provided.

In the first embodiment, the specific drawing object displayed on the second drawing screen is transparent or semi-transparent. However, the entire second drawing screen may be uniformly transparent or semi-transparent. Good.

In the first embodiment, the user changes the predetermined transmittance (transparency) by performing a single gesture operation on a specific drawing object displayed on the second drawing screen. The transmittance may be changed each time the gesture operation is repeated. At this time, the density of the transmittance may be changed according to the direction of the gesture operation.

Further, as an example of changing the transmittance by a gesture operation, the transmittance is changed stepwise by a one-point touch (for example, an operation of sliding a drawing object displayed on the drawing screen while touching it). Point transmission (for example, an operation of sliding while touching two points on a drawing object displayed on the drawing screen) is set to the minimum transmittance, and the two-point touch is performed in the direction opposite to the direction of the gesture operation of the two-point touch. The original transmittance (no transparency) may be changed by performing a gesture operation.

Further, as another example of changing the transmittance by the gesture operation, the transmittance may be changed depending on the direction and speed of the gesture operation. For example, when the gesture motion is fast, it may correspond to the gesture motion by the above two-point touch, and the transmittance may be changed between the gesture motion in the vertical direction and the gesture motion in the horizontal direction.

In the first embodiment, the second drawing screen is displayed so as to overlap the first drawing screen, but there may be a plurality of drawing screens superimposed on the first drawing screen. For example, a third drawing screen may be prepared separately from the second drawing screen, the second drawing object of the second drawing screen is a three-dimensional building, and the third drawing object of the third drawing screen may be POI. it can. In this case, in order to distinguish between the second drawing screen and the third drawing screen, an icon indicating that each drawing screen exists may be displayed on the display surface.

Further, in the first embodiment, the first drawing object is road information, and the second drawing object has been described by taking information on a three-dimensional building (three-dimensional stereoscopic image) as an example. , 20 may be used as drawing objects related to POI information, elevated road information, highway information, and arbitrary registered point information.

In the first embodiment, a three-dimensional building (three-dimensional stereoscopic image) has been described as an example of the second drawing object on the second drawing screen. However, not only artificial buildings but also natural three-dimensional features (such as mountains) Object) may be a drawing object.

In the first embodiment, a two-dimensional map has been described as an example of the first drawing object on the first drawing screen. However, a drawing object by other expression methods such as a Bird View (registered trademark) map may be used.

The input / display unit 1 may have a display surface, the size of the first drawing screen may correspond to the entire display surface, and the size of the second screen may correspond to a part of the display surface. .

In addition, the input / display unit 1 according to the first embodiment includes an input unit that receives user input information and a display unit that displays a map drawing screen based on the received input information and operation control by the control unit 4. However, a configuration for realizing these functions may be provided separately.

Also, the operation can be easily performed by using the touch panel as in the first embodiment and changing the overlap of the drawing screens by the gesture operation. That is, the control of the conventional map display device is performed by touching an operation icon displayed on the touch panel or by a mechanical switch or dial operation, and the user interface is not necessarily easy to use. As described above, a user interface that is easy to use can be realized by using a gesture operation represented by a mobile terminal having a touch panel, which is called a so-called smartphone or the like.

Therefore, it is effective when the operation time is limited, for example, when the map display device mounted on the vehicle is operated. Furthermore, the degree of freedom of fluctuation of the overlap (the direction of movement, the effect at the time of introduction and removal, etc.) is high, and it is possible to meet the requirements including the user's entertaining elements.

Also, it is possible to provide an input mode that is familiar to users familiar with the operation of touch panels.

The input / display unit 1 is not limited to a normal touch panel, and may be a three-dimensional touch panel capable of detecting the proximity and contact of a finger using a capacitance detection type touch panel.

Also, the slide method in the present embodiment is an example, and in the above slide display mode, the map drawing screen may be updated by a method other than the slide method.

In the present invention, the embodiments can be appropriately modified or omitted within the scope of the invention.
