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

As illustrated in FIG. 1, the map display device includes an input / display unit 1 that also serves as an input unit that receives an operation input related to a user's screen display, and a display unit that performs screen display of a plurality of drawing screens. The first information storage unit in which the control unit 4 that controls the display operation of the map drawing screen according to the user's operation input received in step S1 and the drawing object that is referred to when the control unit 4 controls the operation are stored 2 and the second information 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 drawing object) included in the drawing object is not limited to a uniform color, but may be a gradation or a part of the drawing screen. .

Specifically, 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 determines the user's intention from the touch position and operation on the display surface. Is analyzed. 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. The information stored in the first information storage unit 2 and the second information storage unit 3 is not limited to the drawing object related to the map information, but stores other drawing objects to be displayed on the input / display unit 1. be able to.

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

The control unit 4 controls each functional unit provided in the map display device, and displays a map drawing screen or the like on the input / display unit 1. 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 A condition for extracting a drawing object is 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 a detailed conceptual configuration of the control unit 4 in the configuration of the map display device shown in FIG.

The control unit 4 includes an input analysis unit 401 that analyzes input information input from the input / display unit 1, and a first information drawing unit 403 and a second information drawing unit 405 based on the analysis result in the input analysis unit 401. The composite drawing unit 407 is controlled, the overall control unit 402 that displays a map drawing screen or the like on the input / display unit 1, the first drawing object that is the drawing object stored in the first information storage unit 2 is extracted, and the first drawing object is extracted. A first information drawing unit 403 that draws a first drawing screen that is a drawing screen by the first drawing object in the one drawing screen holding unit 404 and a second drawing that is a drawing object stored in the second information storage unit 3 A second information drawing unit 405 that extracts an object and draws a second drawing screen, which is a drawing screen by the second drawing object, in 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 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, and the like 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 and route data to the destination of the vehicle obtained by the route search operation. Can also 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 combines 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 in the composite drawing unit 407, and combines the drawing. Drawing is performed on the screen holding unit 408 (memory unit). The composite drawing screen is held by the composite drawing screen holding unit 408 and then displayed on the input / display unit 1.

The composite drawing unit 407 generates a composite drawing screen by combining the first drawing screen and the second drawing screen so that the respective drawing contents are displayed so as to be wholly or partially overlapped with each other. . In the portion where the first drawing screen and the second drawing screen are overlapped, the drawing object on the drawing screen located above the overlap masks the drawing object on the lower drawing screen, so that only the upper drawing object is visible. It becomes a state. However, if the overlapping of the drawing screens is controlled to eliminate the overlapping, it is possible to make the drawing object on the lower drawing screen visible. 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 combined may have a first attention point and a second attention point, respectively.

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 first drawing object and the second drawing object may have a predetermined relationship. For example, the case where the first drawing screen displays a map of a predetermined geographic range and the second drawing screen displays a map of the same or nearby geographic range as the first drawing screen is given as the predetermined relevance. Further, the first drawing screen displays the vicinity of the vehicle position, whereas the second drawing screen has a relevance on the moving route, such as displaying the route to the destination. In addition, there is a temporal relationship such as the current travel route of the same vehicle and the past travel 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. At this time, if it is displayed in a vertical relationship following the actual space arrangement, it is easier to grasp. For example, a drawing screen that displays an elevated road is superimposed on a drawing screen that displays a general road. The drawing screen for displaying the ground map is superimposed on the drawing screen for displaying the underground map. Note that the stacking order can be changed at any time.

<Basic 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 can display a plurality of map drawing screens in an overlapping manner. Then, since the overlapping state of the map drawing screen is updated to reflect the user operation, the user compares the drawing object on the upper map drawing screen with the drawing object on the lower map drawing screen, and the relationship between the two. Can be easily grasped. During these operations, each functional unit is controlled by the control unit 4, particularly the overall control unit 402.

In the following description, the slide method is used as a specific method of the predetermined operation for updating the display position of the map drawing screen that is overlaid. Although the slide method will be described below, it refers to a method of continuously moving the display position of the drawing screen.

The specific operation of the map display device 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 is in a normal display mode that accepts a normal touch operation.

Next, in step ST11, the user performs a predetermined operation on the initial screen displayed on the input / display unit 1 to shift to the slide display mode. The slide display mode is a mode in which the user can slide the upper map drawing screen by a gesture operation on the input / display unit 1. The display mode is changed by, for example, touch operation, button operation, icon operation, gesture operation, voice input, or the like.

The overall control unit 402 stores a parameter for storing the type of display mode, and by referring to the parameter, it is possible to determine whether or not the display mode is the slide display mode. For example, it is determined whether or not the slide display mode is set when the parameter value is larger or smaller than a predetermined threshold value. The parameter may be set through a user operation such as an icon operation or voice input, or automatically changed according to preset conditions (including the vehicle state and the display state on the display surface). It may be. Further, an icon or the like may be displayed on the display screen of the input / display unit 1 so that the user can visually recognize whether or not the slide display mode is set.

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 slide operation for updating the display position of the map drawing screen overlaid has been performed. The input analysis unit 401 detects a user's input / display unit 1 gesture operation to detect a slide operation.

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 corresponds to information that changes from time to time, such as changes in display contents that change with the movement of the vehicle and changes in traffic jam information.

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. Then, the composite drawing screen is drawn, that is, displayed on the input / display unit 1. Details will be described later.

Next, in step ST18, the overall control unit 402 determines whether or not the input analysis unit 401 has detected a predetermined operation for ending the slide display mode. 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.

<Board slide>
Next, details of step ST17 performed by the composite drawing unit 407 will be described with reference to FIGS. In this step, a composite drawing screen is created. A case will be described in which the second drawing screen is slid out with a board slide from the state in which the second drawing screen overlaps the entire surface of the first drawing screen (full overlap state). . Here, the board slide refers to a slide method in which the drawing object moves in the slide direction in conjunction with the slide. Also, when the drawing screens overlap each other, the upper drawing screen moves and moves out of the display surface. This is called slide out, and all of the drawing screens are out of the display surface due to slide out. Is called complete slide-out. Further, the complete slide-out is also referred to as a total displacement state, paying attention to the state where it does not overlap with the other drawing screen.

In this specification, the second map drawing screen is consistently described as the upper side and the first map drawing screen is the lower side, but the reverse may be possible.

First, in step ST411 of FIG. 4, 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 with respect to the first drawing screen is determined according to the slide distance X0 updated by the slide operation. 5 and 6 schematically show a drawing screen composition method when the display positions of the drawing objects displayed on the drawing screen are different from each other.

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 positions of the first attention point and the second attention point on the display surface are the same).

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.

The user's gesture operation for updating the slide distance X0 includes a drag operation, a shutter operation, and a skip operation.

The drag operation is realized by a gesture operation in which a user moves a predetermined direction while touching a finger touching the display surface, and the drawing screen moves following the gesture operation. When the user performs a drag operation, the overlapping position of the second drawing screen with respect to the first drawing screen is shifted in the finger moving direction by the finger moving distance (sliding distance X0 in FIGS. 5 and 6). In the case of a drag operation in the right direction, a position that is separated from the left end of the first drawing screen by the slide distance X0 in the right direction is determined as the overlap start position. A mode in which a composite drawing screen is created by a drag operation is called a drag mode.

The second drawing screen slid by the drag operation in the drag mode remains in the slid position until the next gesture operation is performed. On the other hand, when the user releases the finger from the display surface after performing the drag operation, the second drawing screen may be returned to the overlapping position before the drag operation. The slide operation in this case is called a shutter operation in distinction from the drag operation, and a mode for creating a composite drawing screen by the shutter operation is called a shutter mode.

Whether the sliding operation is performed in the drag mode or the shutter mode may be set by the user selecting an icon or the like in advance, or the input analysis unit 401 changes the number of fingers touching the display surface or the finger pressure. You may distinguish by detecting etc.

The skipping operation is realized by performing an operation (flicking operation) such as playing a playing card with a finger touching the display surface. When the user performs a skip operation, the overlapping position of the second drawing screen with respect to the first drawing screen is shifted in the direction of the skip operation by a distance corresponding to the skip operation. In the case of a drag operation in the right direction, a position that is separated from the left end of the first drawing screen by the slide distance X0 in the right direction is determined as the overlap start position. Here, since the slide distance X0 (see FIGS. 5 and 6) is an amount that increases with time unlike the drag mode, the second drawing screen slides to the right and finally slides out completely. 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 skip operation of the condition (a) is distinguished from the drag operation by the moving speed of the finger. In addition, 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 drawn on the first drawing screen (data is overwritten) according to the overlapping position determined in step ST412, 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 area of the second drawing screen that does not overlap the first drawing screen (P2 in FIGS. 5 and 6) is not displayed on the display surface. That is, the first drawing object of the first drawing screen having a width of the slide distance X0 that does not overlap the second drawing screen, and the second drawing width D1 from the left end of the second drawing screen (excluding the width of X0 from the right end). The second drawing object (P1 in FIGS. 5 and 6) on the drawing screen is displayed on the display surface.

By sequentially creating the composite drawing screen as described above, it is possible to slide out by the board slide shown in FIG. In FIG. 7, 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. The first background drawing object and the second background drawing object are, for example, rectangular objects painted in cream color with the same size as the drawing screen size. 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.

7, (1a), (2a), and (3a) are schematic views of the lower first drawing screen and the upper second drawing screen as seen from the side, (1b), (2b) (3b) is a schematic view of the first drawing screen and the second drawing screen as seen from the top surface direction.

The user touches the input / display unit 1 with a finger and moves the finger in the right direction in the figure while keeping the touch (drag operation). Then, since the overlapping start position of the upper second drawing screen is sequentially updated (1a → 2a → 3a or 1b → 2b → 3b), the entire second drawing screen moves to the right as if it slides on the board. Is displayed. That is, the drawing objects a, b, and c move to the right as if they are on the board.

In the states (1a) and (1b), the first drawing screen and the second drawing screen are completely overlapped, and the drawing objects A, B, and C are masked by the second background drawing object. When the second drawing screen is smaller than the first drawing screen, the second drawing screen only has to overlap the area of 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 of the input / display unit 1, but the rightmost drawing object c is removed from the display surface and is not displayed. . On the other hand, although the drawing object A is displayed, the drawing objects B and C are masked by the second background drawing object and are not displayed. When the attention point is set, the drawing object A, which is the first attention point, and the drawing object a, which is the second attention point, are displayed close to each other, making it easy to grasp the relationship between the two drawing objects. (See also FIG. 6). 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, with reference to FIGS. 8 to 10, creation of a composite drawing screen using slide-in by board slide will be described. In this case, the map drawing screens do not overlap at all in the initial state (total displacement state), the second drawing screen moves from outside the display surface and gradually overlaps the first drawing screen, and finally Become.

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. 9 and 10 schematically illustrate a drawing screen composition method in the case where display positions of drawing objects displayed on the drawing screen are different from each other.

When the slide distance X0 is 0, the overlapping position is determined so 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 is determined according to the slide distance X0 based on the user's gesture operation.

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. 9 and 10) is not displayed on the display surface. In this state, the first drawing object of the first drawing screen having a width D1 that does not overlap the second drawing screen, and the second drawing object of the second drawing screen of the slide distance X0 from the right end of the second drawing screen (FIG. 9). , 10 P2) is displayed on the display surface.

Next, referring to FIGS. 11 to 13, the slide-in to the right by the board slide will be described. In this case, the second drawing screen moves to the right from outside the display surface and overlaps the first drawing screen.

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. 12 and 13 schematically show a drawing screen composition method in the case where display positions of drawing objects displayed on the drawing screen are different from each other.

When the slide distance X0 is 0, the overlapping position is determined at a position where the second drawing screen is completely outside the display surface. However, it is outside the display surface on the opposite side (right side) from the case shown 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 is determined according to the slide distance X0 based on the gesture operation of the user related to the update.

Next, in step ST443, the second drawing screen is drawn on the first drawing screen in accordance with 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. 12 and 13) is not displayed on the display surface. In this state, the first drawing object of the first drawing screen having a 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. 12, 13 is displayed on the display screen. However, in FIGS. 9 and 10, the left and right arrangements are switched and displayed.

In the above, the operation of the board slide has been described, but there are various variations in the direction of the slide and the movement of the sliding map drawing screen.

<Curtain slide>
Next, creation of a composite drawing screen using a curtain slide (step ST17 in FIG. 3) will be described with reference to FIGS. Here, the curtain slide refers to a slide method in which the display area is continuously changed (increased or decreased) while the display position of the drawing object is fixed. In particular, a case will be described in which the upper second drawing screen slides out in the right direction on the display surface from the fully overlapped state.

It should be noted that which slide method is used to create the composite drawing screen may be distinguished according to the manner of user gesture operation, or may be set in advance according to the combination of maps to be displayed.

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 with respect to the first drawing screen is determined according to the slide distance X0 updated by the slide operation.

When the slide distance X0 is 0, the overlapping position is determined so that the first drawing screen and the second drawing screen completely overlap and the second drawing object masks all the first drawing object. When the attention point is set, it is desirable to determine the overlapping position so that the first attention point on the first drawing screen and the second attention point on the second drawing screen overlap and coincide on the display surface. . That is, when the surrounding map of the vehicle is shown on the first drawing screen and the second drawing screen, it is desirable to determine the overlapping position so that the current position of the vehicle on each drawing screen matches.

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 is determined according to the slide distance X0 based on the user's gesture operation.

In the drag mode, the overlap start position is set with the distance (slide distance X0 in FIG. 15) moved by the user touching the display surface as an offset.

In the shutter mode, the overlapping start position is set in the same manner. However, in the shutter mode, the user touches the display surface, and at the same time, the overlapping position is restored.

In the skip mode, the overlap start position of the second drawing screen is set with an amount that increases with time (the slide distance X0 in FIG. 15 increases with time) as an offset.

Next, in step ST423, the second drawing screen is drawn on the first drawing screen in accordance with the overlapping position, specifically, the overlapping start position. When the second drawing screen is slid 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 coincides with the overlap start position. That is, the position offset by the slide distance X0 from the left end of the second drawing screen coincides with the overlap start position.

The portion (P1 in FIG. 15) removed from the first drawing screen in the second drawing screen 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. 15 is displayed on the display surface.

16 By sequentially creating the composite drawing screen as described above, the operation shown in FIG. 16 (slide out by curtain slide) becomes possible. In FIG. 16, 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 a drawing object B, and the second point of interest on the second drawing screen is a drawing object b. The first background drawing object and the second background drawing object are, for example, rectangular objects painted in cream color with the same size as the drawing screen size. 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.

16, (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) are schematic views of the first drawing screen and the second drawing screen viewed from the top surface direction.

The user performs a drag operation in the right direction of FIG. 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 maintains the display position of the drawing object. It is displayed by sliding to draw (curtain slide).

In the states (1a) and (1b), the first drawing screen and the second drawing screen are in a fully overlapped state, and the drawing object A, the drawing object B, and the drawing object C are respectively masked by the second background drawing object. ing. When the second drawing screen is smaller than the first drawing screen, the second drawing screen only has to overlap the area of 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 of the input / display unit 1, but the leftmost drawing object a is not displayed. On the other hand, although the drawing object A is displayed, the drawing objects B and C are masked by the second background drawing object and are not displayed. 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. When the attention point is set, the drawing object B, which is the first attention point, is displayed at the position where the drawing object b, which is the second attention point, is removed. (See also FIG. 15). 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. However, in FIG. 16, when the gradation is applied so that the drawing object a and its vicinity are cream and the drawing object c and its vicinity are pink. The drawing background colors of 1a), (2a), and (3a) are close to the same pink.

In the curtain slide described above, the range in which the lower first drawing screen can be seen is changed by sliding the second drawing screen without changing the display position of the second drawing object. Here, an example of sliding out to the right of the display surface with a curtain slide has been described. However, the slide direction is not limited to a uniform direction such as left, right, up, down, but may be a slide that progresses radially around the user's touch position. . In addition, various variations are conceivable, such as blinking the second drawing screen or displaying a fade when the slide progresses.

Moreover, although the slide method shown above was able to be slid regardless of where the user touched or operated in the area where the second drawing screen is displayed, the display range of the second drawing screen that accepts the slide operation May be limited. For example, only the area in the vicinity of the boundary with the first drawing screen in the display range of the second drawing screen may be set as an area for receiving the slide operation.

Also, an area for accepting 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.

In the above example, the second background drawing object is a cream rectangular object having the same size as the drawing screen. However, the shape of the background drawing object is not limited to a rectangle, and may be a trapezoid, an ellipse, or a holed object. Also, the color of the background drawing object is not limited to light colors, and a display with a good design can be provided as long as it draws a gradation or a pattern.

In the above example, 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. One drawing object may be generated. For example, the vehicle position mark and the like may be generated by the overall control unit 402 by a program. Further, both or one of the background drawing objects may be generated by the overall control unit 402 by software processing.

In the above example, the method of rendering the background drawing object, which is a rectangular drawing object, on the drawing screen has been described, but the method of generating the background drawing object is not limited to this method. For example, when the drawing screen itself has a function of generating a background color corresponding to the background drawing object, the overall control unit 402 sets the background colors of the first drawing screen holding unit and the second drawing screen holding unit by software processing. It's okay.

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 by software processing. A color may be set.

In addition, the drawing object in this specification is a concept including a display object that is finally displayed on the input / display unit 1 by the above-described software processing.

<Icon display>
When the second drawing screen is in a completely shifted state defined above with respect to the first drawing screen, the first drawing screen is displayed on the entire display screen. In this state, the user is in a state where the second drawing screen is completely slid out and the first drawing screen is displayed on the entire surface, or the second drawing screen is displayed so as to overlap the entire surface of the first drawing screen. It cannot be judged at a glance.

Therefore, when the second drawing screen is completely slid out, a status icon is displayed on the first drawing screen to make the user recognize that the current display screen is the first drawing screen.

The status icon may indicate other information such as whether or not the current display mode is the slide mode in addition to the presence or absence of the slide-out.

Furthermore, a return icon for performing an operation of returning the second drawing screen from the slide-out to the original state may be displayed on the first drawing screen.

FIG. 17 shows a display screen in which a second drawing screen for displaying a POI map in the same geographical area as the first drawing screen is superimposed on a first drawing screen for displaying a planar map. The user can remove the POI map within the slid range by sliding the second drawing screen as necessary, and can display a planar map instead.

Suppose now that the user performs a skip operation and slides the second drawing screen to the right of the display screen. Then, a return icon is displayed as display information on the first drawing screen as shown in FIG. The user grasps that the second drawing screen is currently slid out by looking at the return icon. Further, by pressing the return icon, it is possible to return to the position before the slide-out operation by skipping the second drawing screen.

In FIG. 17, the first background drawing object and the second background drawing object are illustrated as having different colors in order to make the description easy to understand, but the present invention is not limited to this.

18 and 19 are flowcharts of the above operations. FIG. 18 is a flowchart showing the operation of the map display device for an input event.

In FIG. 18, the overall control unit 402 determines the end of the process (step ST700). For example, it is determined that the process has ended when a predetermined command is input from the user or when the power of the apparatus is turned off.

If NO in step ST700, the input analysis unit 401 determines whether or not an input event has occurred in the input / display unit 1 (step ST701). Here, the input event is a user's gesture operation on the touch panel serving as the input / display unit 1 such as a drag operation, a skip operation, or a screen selection.

If there is no input event, the process returns to step ST700 to determine the end of the process. If there is an input event, input analysis section 401 determines whether or not the input event is an input event for the second drawing screen (step ST702). Which drawing screen is the input event is determined from the touch position on the touch panel. When the user touches the display position of the second drawing screen, the input event is determined to be the input event to the second drawing screen. To do. Similarly, when the user touches the display position of the first drawing screen, it is determined that the event is an input event to the first drawing screen, but when the return icon displayed on the first drawing screen is touched. Exceptionally, it is determined that the event is an input event for the second drawing screen.

If there is an input event to the second drawing screen (Y in step ST702), a process corresponding thereto is performed on the second drawing screen (step ST703). Thereafter, processing corresponding to the input event to the second drawing screen is performed on the first drawing screen (step ST704). For example, when there is an input event for sliding the second drawing screen, a process for changing the scale in accordance with a change in the display area of the first drawing screen is performed.

If there is an input event to the first drawing screen (N in step ST702), processing corresponding to the input event is performed on the first drawing screen (step ST705). Thereafter, a process corresponding to an input event to the first drawing screen is performed on the second drawing screen (step ST706). For example, when the map display scale of the first drawing screen is changed, a process of changing the map display scale of the second drawing screen is performed in conjunction with the change.

In the above example, the other image display content is also linked in response to an event on one drawing screen, but this is due to a predetermined operation sequence and is not necessarily an event on one drawing screen. Accordingly, the other image display content does not change. That is, step ST704 and step ST706 are not essential.

FIG. 19 is a flowchart showing details of the process (step ST703 in FIG. 18) corresponding to the input event to the second drawing screen. In FIG. 19, first, the input analysis unit 401 analyzes an input event and determines the type of gesture (step ST720).

If it is determined in step ST720 that the input event is a selection operation, it is determined whether a return icon is displayed on the first drawing screen (step ST721). The selection operation refers to an operation of touching the touch panel once.

If the return icon is in a display state (Yes in step ST721), it is determined that the second drawing screen has been slid out and the user has selected the return icon. Then, the composite drawing unit 407 draws the second drawing screen so as to overlap the first drawing screen, whereby the second drawing screen returns to the display surface (step ST723).

If the return icon is not displayed (No in step ST721), a predetermined process is executed for the selection operation (step ST722). For example, when the second drawing screen displays a POI map, an operation such as displaying related information of the selected point is performed.

If it is determined in step ST720 that the input event is a drag operation, the composite drawing unit 407 creates a composite drawing screen in which the second drawing screen is slid according to the drag direction and drag length, and the input / display unit 1 updates the display. Is done. (Step ST724).

If it is determined in step ST720 that the input event is a skip operation, the composite drawing unit 407 creates a composite drawing screen by sliding the second drawing screen by a predetermined distance according to the skip direction, and the display is updated on the input / display unit 1 (Step ST725). Step ST725 is repeated until the second drawing screen is completely slid out. When it is determined in step ST726 that the second drawing screen is completely slid out, a return icon is displayed at the end of the first drawing screen (step ST727). Here, the first information drawing unit 403 acquires a drawing object from the first information storage unit 2, and draws a new first drawing screen on the first drawing screen holding unit 404 based on the acquired drawing object. Then, the composite drawing unit 407 performs composite drawing using the new first drawing screen, whereby a return icon is displayed on the first drawing screen.

In step ST727, the display position of the return icon is not limited to the screen edge, and may be displayed at an arbitrary position on the screen. However, if the return icon is displayed at the screen edge corresponding to the direction in which the second drawing screen is slid out, the user can know the slide-out direction of the second drawing screen from the position of the return icon. That is, when the second drawing screen is skipped in the right direction of the screen and completely slides out, the return icon is displayed at the right end of the first drawing screen, and the second drawing screen is skipped in the left direction of the screen and completely slides out. In such a case, a return icon is displayed at the left end of the first drawing screen.

FIG. 20 (a) shows a display screen in which a second drawing screen for displaying a three-dimensional map in the same geographical area as the first drawing screen is superimposed on a first drawing screen for displaying a planar map of a road. FIGS. 20B and 20C show a state where the user touches the second drawing screen and performs a slide operation in the right direction. The second drawing screen is slid out by the board slide, and the drawing object of the planar map is displayed in the area where the second drawing screen is removed. FIG. 20D shows a state where the second drawing screen is completely slid out, and a return icon is displayed at the right end of the first drawing screen.

<Thread display>
In order to prevent an adverse effect that the user cannot grasp whether or not the second drawing screen has been slid out, a predetermined end portion of the second drawing screen may be always overlapped with the first drawing screen. In the following description, for convenience of explanation, a state in which a predetermined end of the second drawing screen overlaps the first drawing screen may be referred to as a total displacement state.

FIG. 21 shows a display screen in which a second drawing screen for displaying a POI map in the same geographical range as the first drawing screen is superimposed on a first drawing screen for displaying a planar map. The user can remove the POI map within the slid range by sliding the second drawing screen as necessary, and can display a planar map instead.

Suppose now that the user performs a skip operation and slides the second drawing screen to the right of the display screen. Then, when the display area of the second drawing screen becomes less than the predetermined width, the sliding operation ends, and as shown in FIG. 22, a predetermined end portion of the second drawing screen, that is, an area having a predetermined width from the left end is used as a thread. Is displayed. Even if the user touches the sled and drags in the right direction, the second drawing screen is not slid rightward any more.

The user can see that the second drawing screen is being slid rightward on the screen by looking at the thread display. Further, the user can slide in the second drawing screen by touching the thread on the touch panel and dragging or skipping the screen leftward. That is, the thread is an operation image for returning the second drawing screen to the first drawing screen.

FIG. 22 shows a flowchart of processing (step ST703 in FIG. 18) for an input event to the second drawing screen when performing thread display.

22, first, the input analysis unit 401 determines the type of gesture for the input event (step ST730). If it is determined that the input event is a selection operation, a predetermined action is executed for the selection operation (step ST731). For example, when a POI map is displayed on the second drawing screen, an operation such as displaying related information of the selected point is performed.

If it is determined in step ST730 that the input event is a skip operation, the composite drawing unit 407 creates a composite drawing screen by sliding the second drawing screen by a predetermined distance according to the skip direction, and the display is updated on the input / display unit 1 Is done. (Step ST733). After that, the overall control unit 402 determines whether or not the display width of the second drawing screen is equal to or smaller than a predetermined value (step ST734). 2 Continue sliding the drawing screen.

If it is determined in step ST730 that the input event is a drag operation, the composite drawing unit 407 creates a composite drawing screen in which the second drawing screen is slid according to the drag direction and drag length, and the input / display unit 1 updates the display. Is done. (Step ST732). If the second drawing screen is displayed as a thread and the drag gesture is performed on the thread, the second drawing screen is threaded in according to the drag operation.

In the above embodiment, the drawing screen to be slid out is one second drawing screen. However, in a map display device that displays three or more drawing screens in an overlapping manner, a plurality of drawing screens may be slid out. For example, when the third drawing screen is displayed over the second drawing screen and both the second drawing screen and the third drawing screen are completely slid out (totally shifted state), the second drawing screen and the third drawing screen are displayed. You may display two icons that let you know the existence of. When the icon is a return icon, the second drawing screen and the third drawing screen can be slid in on the first drawing screen separately, so that information can be superimposed according to the purpose and is very convenient to use. A user interface can be realized.

Further, instead of the icon, a thread indicating the presence of the third drawing screen may be displayed on the thread indicating the presence of the second drawing screen. In this case, the thread width of the second drawing screen is displayed wider than the thread of the third drawing screen. As described above, a plurality of threads are displayed on the staircase so that any thread can be operated independently. These are display methods suitable for displaying a plurality of highly related maps such as maps of different ages.

<Others>
As another method for preventing the adverse effect that the user cannot grasp whether or not the second drawing screen has been completely slid out, it is automatically restored when a predetermined time elapses after the second drawing screen is completely slid out. May be.

In addition, various operations for improving the usability of the map display device can be considered. The enlargement / reduction of the first and second drawing screens may be realized by the user touching two points on the touch panel. That is, for example, the screen is touched at two places, such as the thumb and the index finger, and the reduction operation is performed by narrowing the interval between the two points while being touched, and the enlargement operation is performed by increasing the interval between the two points.

As shown in FIG. 23, when the first drawing screen is an entire route diagram from the periphery of the vehicle position to the destination and the second drawing screen is a map of the vehicle position periphery, the second drawing screen is displayed with a finger. By dragging in the right direction while touching the display area, the second drawing screen can be slid to display the destination map. Further, the size of the second drawing screen can be reduced and the display area of the first drawing screen can be expanded by a gesture of touching the second drawing screen with two points and reducing the interval between the two points.

FIG. 24 is a diagram in which the second drawing screen in FIG. 23 is displayed smaller than the first drawing screen. Thus, if the upper drawing screen is displayed in a small size, the user can easily recognize which is the upper drawing screen, that is, the drawing screen to be slid.

If the input / display unit 1 is a three-dimensional touch panel, the drawing screen can be controlled by a non-contact gesture. For example, the drawing screen may be enlarged when a finger is brought close to the touch panel and reduced when the finger is moved away from the touch panel. Alternatively, the second drawing screen may start sliding when the distance between the finger and the touch panel becomes a predetermined value or less, and may slide out when the finger touches the touch panel.

Further, an operation for switching the display contents of the first drawing screen and the display contents of the second drawing screen, and an animation of turning the map book may be realized by a predetermined gesture.

Also, the second drawing screen during the slide may be displayed as a semi-transparent display.

<Modification>
The input / display unit 1 has a configuration in which 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 are integrated. The structure for realizing these functions may be provided separately. Moreover, the information to be displayed is not limited to the information on the map drawing screen, and various information according to the user's request can be displayed.

In addition, if the input / display unit 1 is realized by a touch panel as in the present embodiment and the overlap of the drawing screens is changed by a gesture operation, the operation can be easily performed. In conventional map display devices, screen operations are performed by touching operation icons displayed on a touch panel, mechanical switches, or dial operations, and the user interface is not always easy to use. However, a user interface that is easy to use can be realized by adopting a gesture operation that is used in a mobile terminal having a touch panel, such as a smartphone, as in the present invention.

Therefore, it is effective for screen operation of a map display device used in an environment where operation time is limited, such as a map display device mounted on a vehicle. Furthermore, by providing a degree of freedom in the sliding direction of the drawing screen and the display effect of the drawing screen during the slide, an entertaining element can be added to the screen operation.

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.

The first information storage unit 2 and the second information storage unit 3 may be different storage media as shown in FIG. 1, or may be a case where both are included in one storage medium. Moreover, the case where map information etc. are acquired by communicating with the storage medium provided outside may be sufficient.

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.

Also, the upper drawing screen and the lower drawing screen do not need to have the same size. Note that the drawing screen does not have to be the size of the entire display surface.

Note that the map information displayed on the first drawing screen and the second drawing screen can be interchanged with each other.

In addition, it has been described that the selection of the return icon skips the second drawing screen and slides in the arrangement before the operation. However, one end of the second drawing screen is displayed on the end of the display screen, and the user touches and drags the one end. You may enable it to slide in the 2nd drawing screen to arbitrary positions by operating.

<Effect>
The map display device of the present embodiment is a map display device that can at least partially overlap a plurality of screens including a first drawing screen and a second drawing screen. The first drawing screen displays at least one first drawing object, the second drawing screen displays at least one second drawing object, and at least one of the first drawing object and the second drawing object includes map information. The first drawing screen and the second drawing screen have the same or different sizes. The map display device controls an overlapping state of the first and second drawing screens in accordance with an input unit that receives an operation input related to a user's drawing screen display and a user's operation input received by the input unit. The overlapping portion of the two drawing screens includes a control unit 4 in which one of the first and second drawing objects masks the other and outputs to the display unit, and the display screen of the display unit corresponds to the entire first drawing screen. When the second drawing screen is completely displaced from the first drawing screen, an operation image for returning the second drawing screen to the first drawing screen is displayed on the display screen. When the second drawing screen is completely displaced from the first drawing screen, that is, when it slides out, the user can confirm the presence or absence of the slide-out by the operation image, and can return the slide-out second drawing screen. Since it is possible, it becomes an easy-to-use map display device.

Further, the control unit 4 continuously changes the overlapping state of the first and second drawing screens by sliding the other of the first and second drawing screens. For example, when the maps having the same geographical range and displaying different information are used as the first and second drawing screens, the overlapping state of these maps continuously changes, so that the user can recognize the relationship between the two maps. Easy to grasp.

Also, the slide includes a board slide in which the drawing object on the drawing screen moves in the slide direction in conjunction with the slide on the drawing screen, and a curtain slide in which the position of the drawing object displayed on the display unit does not change. Regardless of the slide method, the user can easily understand the relationship between the two maps by continuously changing the overlapping state of the maps.

In addition, since the input unit and the display unit are integrally formed as the input / display unit 1 of the display device with a touch panel, the convenience of the user's input operation is improved.

Further, since the operation image for returning the second drawing screen to the first drawing screen is a return icon as the first drawing object, the user selects the return icon to change the first drawing screen to the first drawing screen. It is possible to return to the drawing screen.

The total displacement state of the second drawing screen with respect to the first drawing screen includes a case where only a predetermined end portion of the second drawing screen overlaps the first drawing screen, and the second drawing screen is displayed on the first drawing screen. Since the operation image for returning to the screen is the predetermined end portion, the user can confirm the presence or absence of the slide-out by the predetermined end portion, and can return the slide-out second drawing screen.

The map display method of the present embodiment is a map display method for displaying a plurality of drawing screens including a first drawing screen and a second drawing screen at least partially overlapping each other. The first drawing screen displays at least one first drawing object, the second drawing screen displays at least one second drawing object, and at least one of the first drawing object and the second drawing object relates to map information. The first drawing screen and the second drawing screen including the drawing object have the same or different sizes.
