A plurality of detailed menus are also associated with the other main menu items, but the details of these detailed menu items are not shown.

(Operation of display device 1)
Next, the operation of the display device 1 according to the first embodiment will be described with reference to FIG. 4 and FIGS. 5A to 5E.

  FIG. 4 is a flowchart illustrating an example of the operation of the display control unit 101 of the display device 1. 5A to 5E show examples of screen display displayed on the display panel 121 by the operation of the display control unit 101 according to the flowchart of FIG.

  When the power of the display device 1 is turned on, the display control unit 101 displays an initial screen 121a illustrated as an example in FIG. 5A on the display panel 121 (Step 1).

  As shown in FIG. 5A, eight objects corresponding to each main menu item of the main menu hierarchy 40 are displayed on this initial screen. More specifically, the first object 41 is displayed corresponding to the main menu item “air conditioner”, and similarly, “seat”, “navigation”, “audio”, “others”, “running support”, The second to eighth objects 42 to 48 are displayed in correspondence with the main menu items of “vision assistance” and “light”, respectively.

  The first to eighth objects 41 to 48 are displayed as images in which character information indicating the corresponding main menu item is superimposed on an elliptic symbol. The first to eighth objects 41 to 48 are displayed along the annular symbol 49 so as to surround the center point 49 a of the annular symbol 49.

  In addition to the first to eighth objects 41 to 48 and the annular symbol 49, an arrow-shaped pointer 5 is displayed on the initial screen 121 a. The initial position of the pointer 5 is a position (indicated by a two-dot chain line in FIG. 5A) where the center point 49a is pointed by the tip 5a of the arrow shape of the pointer 5. The tip 5a indicates the position indicated by the pointer 5.

  For example, as shown in FIG. 5A, the initial screen 121a has a coordinate system in which the lower left corner of the screen is the origin, the horizontal direction is the X axis, and the vertical direction is the Y axis.

  Next, the display control unit 101 acquires information on the X-axis coordinate and the Y-axis coordinate of the user's designated position detected by the designated position detection unit 102 based on the swing direction of the operation knob 131b of the pointing device 131 (Step 2). ).

  Next, the display control unit 101 generates image information in which the display position of the pointer 5 is moved so that the tip 5a of the pointer 5 indicates the coordinates of the user's designated position acquired in Step 2, and the image information is displayed. The data is sent to the display unit 12 (Step 3). As a result, the display position of the pointer 5 moves in the direction of the arrow A from the position indicated by the two-dot chain line in FIG. 5A to the position indicated by the solid line, for example.

  Next, the display control unit 101 calculates the distance between the indication position of the pointer 5 and the center position of the display area of the first to eighth objects 41 to 48, and whether the distance is equal to or less than the first threshold value. It is determined whether or not (Step 4).

  When the distance between the indicated position of the pointer 5 and the position of the center of any one of the display areas of the first to eighth objects 41 to 48 is equal to or smaller than the first threshold, the display control unit 101 displays the object and its surroundings. The image information to be sent to the display unit 12 is changed so that the object displayed on the screen is gradually enlarged and displayed according to the distance from the designated position of the pointer 5 (Step 5).

  For example, when the distance D1 between the indicated position of the pointer 5 indicated by the solid line in FIG. 5A and the center 42a of the display area of the second object 42 is equal to or less than the first threshold value, the display control unit 101 is shown in FIG. 5B. Like the enlarged display screen 121b, the second object 42 and the objects displayed in the vicinity thereof are gradually enlarged and displayed according to the distance D1. The example shown in FIG. 5B shows a state where the first to third objects 41 to 43 are enlarged and displayed 1.3 times the initial screen.

  The first threshold is set to a value that satisfies the determination condition of Step 4 in a state where the indicated position of the pointer 5 does not overlap the display range of any of the first to eighth objects 41 to 48. In the example shown in FIG. 5A, the distance D1 is equal to or smaller than the first threshold value in a state where the pointing position of the pointer 5 is located outside the outline 42b indicating the boundary between the display range of the second object 42 and the background. Thus, the first threshold value is set. That is, the first to third objects 41 to 43 are enlarged and displayed when the indicated position of the pointer 5 approaches the display range of the second object 42.

  Next, the display control unit 101 calculates the distance between the center position of the enlarged object and the designated position of the pointer 5, and determines whether or not the distance is equal to or smaller than the second threshold (Step 6). . If the result of this determination is No, the distance between the center position of the object and the indicated position of the pointer 5 is obtained by performing the process of acquiring the information on the user's designated position and the process of moving the display position of the pointer 5 again. Is determined to be less than or equal to the second threshold.

  On the other hand, when the determination result is Yes, the display control unit 101 refers to the menu item information 111 and shows the detailed menu item associated with the main menu item indicated by each object displayed on the enlarged display screen 121b. The sub-object is displayed on the screen (Step 7). At this time, the display control unit 101 causes the sub-object so that a plurality of sub-objects corresponding to the object whose distance between at least the indicated position of the pointer 5 and the center position is equal to or smaller than the second threshold value are all displayed on the screen. Adjust the display position of.

  For example, when the distance D2 between the indicated position of the pointer 5 shown in FIG. 5B and the center 42a of the display area of the enlarged second object 42 is equal to or smaller than the second threshold, the display control unit 101 displays the information shown in FIG. As shown, the sub-object 421 indicating “seat heater”, the sub-object 422 indicating “slide”, and the “vertical” are detailed menu items associated with the main menu item “sheet” indicated by the second object 42. A sub-object 423 indicating “memory” and a sub-object 424 indicating “memory” are displayed on the detailed menu screen 121c.

  The second threshold is set to a value that satisfies the determination condition of Step 6 in a state where the second threshold is smaller than the first threshold and the pointing position of the pointer 5 does not overlap the display range of any of the objects displayed in an enlarged manner. Yes. That is, a plurality of sub-objects are displayed when the designated position of the pointer 5 approaches the display range of the enlarged object.

  In the example shown in FIG. 5C, the sub-object 411 indicating “A / C” which is a detailed menu associated with the main menu item “air conditioner” indicated by the first object 41 adjacent to the second object 42, “ A destination associated with the main menu item “navigation” indicated by the sub-object 412 indicating “mode”, the sub-object 413 indicating “air flow”, the sub-object 414 indicating “temperature”, and the third object 43 is set. A sub-object 431 indicating “Destination”, which is a detailed menu for the purpose, is displayed on the detailed menu screen 121c.

  Furthermore, in the example shown in FIG. 5C, the display position of each sub-object on the initial screen 121a corresponds to the display position of the object indicating each main menu item with the center position 49a of the annular symbol 49 as the center. It is annularly arranged at the position. The display order is set based on the relevance with the contents of the main menu item indicated by the object. For example, the detailed menu item “seat heater” indicated by the sub-object 421 is associated with the main menu item “seat”, but “sheet heater” is also related to temperature adjustment, so the display areas of the sub-objects 421 to 424 are displayed. Of these, the sub-objects 411 to 414 indicating the detailed menu items associated with the main menu item “air conditioner” related to temperature adjustment are displayed at positions closest to the display area.

  Next, the display control unit 101 refers to the information on the user's designated position detected by the designated position detection unit 102, and determines whether the designated position has moved in the circumferential direction centered on the center position 49a (Step 8). . In this determination, the direction of movement of the designated position is the circumference around the center position 49a, except when the designated position is not moved and when the designated position is moved only in the radial direction around the center position 49a. When it has a directional component, it is determined that it has moved in the circumferential direction.

  When the determination result in Step 8 is Yes, the display control unit 101 moves the sub-object of the detailed menu item to be arranged in the position in the circumferential direction of the designated position within the display range of the detailed menu screen 121c. In this way, the display position of each sub-object is changed (Step 9).

  For example, as illustrated in FIG. 5D, when the display position of the pointer 5 moves in the direction of arrow B (clockwise), the display control unit 101 moves the third object 43 to the third object 43 in the clockwise direction of the sub-objects 421 to 424. The display position of each sub-object is changed so that the associated sub-object 432 is displayed. The sub object 432 is associated with the main menu item “navigation” and indicates a detailed menu item “home” for setting a position on the map set in advance as a home as a destination.

  As described above, when the target object is not found in the sub-object displayed on the detailed menu screen 121c, the user moves the pointer 5 to indicate the detailed menu item outside the display range of the detailed menu screen 121c. Display sub-objects.

  Next, the display control unit 101 refers to the detection result of the selection detection unit 103 and determines whether any of the sub-objects displayed on the detailed menu screen 121c is selected by the user (Step 10). When any sub-object is selected by the user, the display control unit 101 changes the display mode such as the color and size of the selected sub-object or the thickness of the line. If no sub-object has been selected, the process of acquiring information on the user's designated position and the process of moving the display position of the pointer 5 are performed again, and the processes after Step 8 are repeatedly executed.

  For example, as illustrated in FIG. 5E, when the switch 132 is pressed in a state where the indication position of the pointer 5 is included in the display range of the sub-object 421 of “seat heater”, the selection detection unit 103 indicates that the sub-object 421 Detects selection. Then, the display control unit 101 refers to this information, changes the display mode of the sub-object 421, and displays on the detailed menu screen 121c that the user can visually recognize that the sub-object 421 has been selected (Step 11). In the example shown in FIG. 5E, the display mode is changed so that the line indicating the outer edge of the sub-object 421 is thickened.

  Next, the display control unit 101 causes the display panel 121 to display an individual setting screen for setting the detailed menu item indicated by the selected sub-object (Step 12). The display content of the individual setting screen is stored in advance as individual setting screen information 112 in the storage unit 11 for each detailed menu item.

  The user moves the pointer 5 with the pointing device 131 on the screen on which the individual setting screen is displayed, and sets each part of the vehicle by operating the switch 132. The setting content set by the user is transmitted to the corresponding in-vehicle device (Step 13).

  For example, as shown in FIG. 5C, when the sub object is displayed and the pointing position of the pointer 5 moves away from the display position of the sub object, the sub object is changed to, for example, as shown in FIG. 5B. An object may be displayed, and when the pointing position of the pointer 5 is further away from the display position of the object in this state, an initial screen may be displayed as shown in FIG. 5A, for example. .

(Effects of the first embodiment of the present invention)
The above-described first embodiment of the present invention has the following effects.
(1) Of the objects shown on the initial screen, those close to the position indicated by the pointer 5 are enlarged and displayed, so that even when a large number of objects are displayed, the user can easily view the displayed contents of the objects. Visibility and selectivity are improved.
(2) When the designated position of the pointer 5 approaches the object, a sub-object associated with the object is displayed. Therefore, in order to display the sub-object, for example, the switch is performed by aligning the designated position of the pointer 5 with the object. There is no need to push in 132 or the like, and the operation from the initial screen until the sub-object is displayed can be performed as a series of operations using only the pointing device 131. For this reason, operations from displaying the initial screen to selecting the sub-object can be performed in a short time.
(3) Since the sub-objects not displayed on the detailed menu screen 121c are sequentially displayed according to the movement of the pointer 5 in the circumferential direction, when the display of the object is switched to the display of the sub-object, the user aims Even when the sub object indicating the detailed menu item is not displayed, for example, it is not necessary to return to the initial screen, and the sub object indicating the target detailed menu item can be displayed.
(4) Since the display position of the sub-object on the detailed menu screen 121c is set based on the relevance with the contents of the main menu item indicated by the object, the user can easily find the sub-object indicating the target detailed menu item. Thus, the selectivity is improved.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. 6A and 6B.

  In the first embodiment, when the pointing position of the pointer 5 approaches one of the objects, the display device 1 is configured to enlarge and display both the object and the other object. In the embodiment, only the object whose pointing position of the pointer 5 is close is displayed in an enlarged manner. Further, in the first embodiment, when the indicated position of the pointer 5 further approaches the display range of any of the enlarged objects, the sub-objects related to all the objects displayed on the screen are displayed. However, in the second embodiment of the present invention, only the sub-object associated with the object whose pointing position of the pointer 5 approaches is displayed on the screen. Note that, in the second embodiment of the present invention described below, portions having the same configuration and function as those of the first embodiment are denoted by common reference numerals, and description thereof is omitted.

  FIG. 6A corresponds to FIG. 5B in the first embodiment, and shows an example of the enlarged display screen 121d when the pointer 5 approaches the second object 42 from the initial screen shown in FIG. 5A. As shown in FIG. 6A, when the indicated position (tip portion 5a) of the pointer 5 approaches the display range of the second object 42, the second object 42 is displayed in an enlarged manner than the other objects.

  More specifically, the center position 42a of the second object 42 is unchanged compared to the initial screen, and the size is enlarged and displayed 1.3 times. The display positions and sizes of the first object 41 and the third to eighth objects 43 to 48 are the same as those of the initial screen.

  FIG. 6B corresponds to FIG. 5B in the first embodiment, and the pointing position of the pointer 5 further approaches the second object 42 in a state where the second object 42 is enlarged and displayed. An example of the detailed menu screen 121e in a state where the sub objects 421 to 424 associated with the object 42 are displayed is shown.

  In the detailed menu screen 121e shown in FIG. 6B, sub objects 421 to 424 are displayed instead of the second object 42 displayed on the enlarged display screen 121d shown in FIG. 6A. The display positions of the sub-objects 421 to 424 are set along the annular symbol 49, and the first object 41 and the third to eighth objects 43 to 48 are arranged so as to reduce the interval along the annular symbol 49. Is displayed.
