In a display device with a touch operation function, for example, a display device and an operation pad for performing a touch operation are separately provided, and a touch position on the operation pad corresponding to a display screen on the display is detected by an optical sensor. .

More specifically, a light projecting element and a light receiving element are arranged so as to form a plurality of parallel optical axes corresponding to the vertical and horizontal directions of the operation pad, and the surface of the operation pad is touched with a finger. At this time, the light emitted from the light emitting element and reaching the light receiving element is blocked by the finger, whereby the position of the finger on the operation pad is determined, and the coordinate position based on the determination result is output. The coordinate position of the finger is converted into a coordinate position on the display and displayed on the display.

On the other hand, in a car navigation system,
With the advancement of information and the improvement of the processing capability of the microcomputer, a wide variety of functions such as voice guidance and various search functions are provided. Generally, a vehicle speed sensor or the like is connected to the navigation system. When the vehicle speed sensor determines that the vehicle is running, only simple operations can be performed, and safety during running is ensured. When is stopped, it is possible to use functions that require complicated operations such as setting of destinations and voice guidance, various searches, and the like.

[0005] With the widespread use of wide-screen displays, a display device provided in a vehicle is also provided with a wide-screen display. By using a wide-screen display, it is possible to increase the number of operation items displayed on the display when the vehicle is stopped, thereby enabling input of various types of information using a 50-sound input or the like. Become.

On the other hand, in a display device with a touch operation function, when displaying a large number of operation items on a wide screen display, an input pad for the touch operation is also provided on the wide screen in order to eliminate operation errors and uncomfortable touch operation. It is preferable to make it wider in total.

[0007]

However, when the operation surface of the operation pad is widened in accordance with the display, the movement of the finger on the operation surface becomes large. For this reason, when an operation item that can be operated while the vehicle is running is displayed in a large size, the movement of a finger on the input pad increases, which may cause a feeling of strangeness in the operation or a burden on the operation.

[0008] The present invention has been made in view of the above-mentioned facts. Even when the number of operation items displayed on the display is changed, a touch operation can be smoothly performed without a sense of incongruity, and operability is improved. It is an object of the present invention to propose a display control device.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a vehicle, wherein an operation area is vertically and horizontally corresponding to the maximum number of divided areas obtained by dividing a display area on a display vertically and horizontally. The operation position on the divided operation pad is detected by the operation position detection means to determine which division area on the operation pad, and the divided area on the display corresponding to the detected division area on the operation pad is operated. A display control device to display on a display as a position, when the number of divisions on the display is changed,
Area selection means for selecting an operation area on the operation pad according to the changed number of divisions, and conversion for converting an operation position in the operation area selected by the area selection means into a division area on the display for display Means.

According to the present invention, when a large number of operation items are displayed on the display, the divided areas on the operation pad correspond to the divided areas on the display as they are, but when the display is largely divided, The operation area on the operation pad is narrowed according to the number of divisions.

[0011] Thus, when the operation items are displayed large on the display, a touch operation can be performed in a narrow operation range, and when tracing on the operation pad, there is no need to move the finger greatly, and there is no discomfort. Operation can be performed, and operability can be improved.

According to a second aspect of the present invention, when the operation position detected by the operation position detection means is around the selected operation area on the operation pad, the operation position is set to the selected area. It is characterized by conversion.

According to the present invention, when a touch operation is performed on the operation pad outside the operation area while the operation area is being narrowed, for example, conversion is performed assuming that a touch operation is performed on the closest divided area in the operation area.

As described above, when a touch operation is performed outside the selected operation area, the operation is converted into the selected operation area, thereby preventing the touch operation from being wasted.

The invention according to claim 3 is characterized in that, when the number of divisions to be changed is set in advance, partition means for partitioning an operation area selected on the operation pad is formed. I do.

According to the present invention, the partition means is formed on the operation pad so that when the operation area is narrowed, the outer periphery of the operation area corresponding to the outer peripheral area on the display becomes clear. Thereby, even when the operation area is narrowed, the touch operation can be performed by the blind touch, and the operability is not reduced.

The operation area partitioned by the partitioning means can be provided at a central portion on the operation pad.

The partitioning means may be a projection formed on the operation pad, or may be a step forming a low portion and a high portion on the operation pad.

When the partitioning means is formed by the projections and the steps, the projections and the steps should not be made unnecessarily large and only need to be recognized when touched by a finger. Even if is formed, the operational feeling and operability are not impaired.

Further, the display control device of the present invention includes a traveling detecting means for detecting a traveling state of the vehicle, and the area selecting means selects an operation area on the operation pad based on a detection result of the traveling detecting means. It may be something.

The control unit 56 is connected to a vehicle speed sensor 58 and a parking brake switch 60 as travel detecting means. The control unit 56 controls the vehicle based on signals from the vehicle speed sensor 58 and the parking brake switch 60. The vehicle traveling state, such as whether the vehicle is traveling or not, is determined.

On the other hand, in the display system 10, an operation menu is set according to the display screen of the display 12. For example, when a map screen for navigation is displayed on the display 12, an operation menu for navigation is displayed, and when a TV screen is displayed, an operation menu for performing processing such as channel switching is displayed. You.

When the display of the operation menu is requested, the control unit 56 displays the screen displayed on the display 12 and the operation menu set according to the running state of the vehicle. That is, the operation menu is switched depending on whether the vehicle is stopped or running.

Thus, in the display system 10, when the vehicle is running, the operation items are displayed large on the display 20, and the number of layers for performing the displayed operation is reduced. Also, when the vehicle is stopped,
An operation menu for inputting the Japanese syllabary is displayed, and a complicated operation divided into several layers can be performed.

The display system 10 uses a wide-screen display 20, and when the vehicle is stopped, a large number of operation items can be displayed on the display 20. Further, in the display system 10, when the vehicle is running, the screen of the display 20 is largely divided, and, for example, operation items set to be operable even while the vehicle is running are displayed in large size.

In the display system 10 applied to the present embodiment, while the vehicle is stopped, the screen of the display 12 is divided into 12 × 5, as shown in FIG. indicate. Thus, a large number of operation items can be displayed on the display 12, and for example, a Japanese syllabary input menu 206 as shown in FIG. 14B can be displayed.

Further, in the display system 10, as shown in FIG. 6B, the screen of the display 20 is divided into 6 × 3, and the number of operation items to be displayed is reduced. It is designed to be displayed large so that it can be easily displayed.

The upper part is divided to determine the operation position. The control unit 54 converts an area detected by the touch tracer controller 54 of the touch tracer 16 into an area on the display 12 and displays the area.

That is, as shown in FIGS. 6A and 7A, the controller 56 of the display system 10
Then, the display area of the display 12 is defined by coordinates A ₁ B _{1 to} A _12.
When divided into B _5, an input pad over 36, just as 12 × 5 (coordinate a ₁ b ₁ ~a ₁₂ b and the display 12 above
Dividing the region of _5), coordinates a _n b on the input pad 36
_m (1 ≦ n ≦ 12, 1 ≦ m ≦ 5) on the display 20
The coordinates are made to correspond to the upper coordinates A _n B _m . Thus, the operation position on the input pad 36 can be displayed on the display 12 by the absolute coordinate conversion.

As shown in FIGS. 7A and 8A, the input pad 36 has a lower portion 62 formed at the center. The lower portion 62 is slightly lower than the higher portion 64 due to the formation of a step 66 between the lower portion 62 and the higher portion 64 on the periphery of the input pad 36. Lower part 6
The height difference between 2 and the high portion 64 is set so that, for example, when a trace is made on the input pad 36, the fingertip does not feel uncomfortable and the boundary between the low portion 62 and the high portion 64 is clear. (For example, about 0.5 mm to 1.0 mm). Thus, the touch tracer 16 can recognize the outer periphery of the input range of the input pad 36 even with a blind touch.

The lower portion 62 has a shape similar to the screen of the display 12 (the planar shape of the input pad 36). Further, as shown in FIG.
Is such that, when the display 12 is divided into 6 × 3 areas (see FIG. 6B), the coordinates a ₄ b _{2 to} a ₉ b ₄ are positioned so as to face the respective areas. Has become.

The control unit 56 switches between an operation area 68 formed by the lower part 62 and the higher part 64 of the input pad 36 and an operation area 70 formed by the lower part 62 according to the display on the display 12. It has become.
That is, when the display on the display 12 is divided into 12 × 5, the touch operation can be performed in the operation area 68, and when the display on the display 12 is divided into 6 × 3, the touch operation can be performed in the operation area 70. I have to.

Thus, the operation area 7 by the lower part 62
When 0 is selected, the relative coordinate conversion, the coordinate a ₄ b ₂ ~a ₉ b ₄ in the operation area 70, the coordinates C ₁ D ₁ ~C ₆ on the display 12 shown in FIG. 6 (B) is converted into D ₃ are to be displayed on the display 12.

When the control section 56 detects a touch operation on the high-order section 64 while selecting the operation area 70 on the input pad 36, the control section 56 selects the operation area 70 closest to the detected operation position. It is determined that a touch operation has been performed. For example, when the user touches the coordinate a ₁₂ b ₁ , it is determined that the touch operation has been performed on the coordinate a ₉ b ₂ in the operation area 70, thereby preventing the touch operation from being wasted. .

In the present embodiment, as an example, a part of the region on the input pad 36 is
Areas C ₁ D _{1 to} C _{6 of} display 12 divided into × 3
Although it was formed so as to correspond to D ₃ , for example, FIG.
As shown in FIG. 8B, a projection such as a rib 72 may be formed on the surface of the input pad 36 instead of the step 66 as the partitioning means. At this time, the rib 72
When tracing on the input pad 36, the operation area 70
Should be clear and the height should not cause a sense of incongruity due to a fingertip being caught.

The operation of the present embodiment will be described below with reference to the drawings.

The display system 10 is turned on by operating the power switch 18 provided on the remote controller 14, and an operation menu for selecting a screen to be displayed on the display 12 is displayed on the display 12. By selecting a desired screen from the operation menu, a screen based on the image data output from the selected attached device is displayed on the display 12. By selecting the display of the operation menu on each screen, an operation menu in which operation items corresponding to the displayed screen are set is displayed on the display 12, and a desired process or the like can be performed from the operation menu. Can be done.

The screen display on the display 12 and the processing for the display screen are performed by the remote controller 14.

At the same time, in the display system 10, when the operation items are displayed by dividing the display 12 into large parts, the touch operation is performed in the operation area 70 provided at the center of the input pad 36 of the touch tracer 16. The input pad 36
The finger movement on the top is reduced so that the touch operation can be performed smoothly. Therefore, in the touch tracer 16, when the operation items are displayed large on the display 12, such as when the vehicle is running, the movement of the finger on the input pad 36 can be reduced.

A step 66 is provided on the input pad 36.
Is provided to clarify the operation area 70. Thus, the display system 10 can smoothly and accurately perform an operation input by a blind touch.

Note that the present embodiment described above does not limit the configuration of the present invention. The present invention can be applied to a display device having an arbitrary configuration having a touch operation input function.

In this embodiment, the input pad 36
A stepped portion 66 is provided as a dividing means at the center of the operation area so that the operation area 70 can be clearly determined, but the setting position of the operation area is not limited to this. For example, FIG.
As shown in FIGS. 15A and 15B, a step portion 90 or a rib 92 is formed as a partitioning means at the lower left of the input pad 36 (the lower left side in FIG. 15) and partitioned by the step portion 90 or the rib 92. The arranged operation area 70 may be arranged. In this case, the coordinates a ₆ on the input pad 36
b _{1 to} a ₁₂ b ₃ are coordinates C ₁ D _{1 to} C ₆ D _{3 of the} display 12
(Relative coordinate conversion).

Further, a plurality of operation areas are displayed on the input pad 36.
The region 70 may be formed. For example, FIG.
(A), as shown in FIG.
6 to form an operation area 70 on each of the left and right sides.
The coordinates a on the input pad 36 ₁b_Two~ A₆b_FourAnd coordinates a
₇b_Two~ A₁₂b_FourStep 94 or rib
Form 96.

Thus, if the remote controller 14 is attached to the center console of the vehicle, touch operations can be performed from either the driver's seat side or the passenger's seat side of the vehicle.

[0090]

As described above, according to the present invention, when the display is largely divided horizontally and vertically, the operation area on the operation pad is selected so as to be narrowed. This can reduce the movement of the finger on the operation pad, improve the operability when selecting an operation item displayed on the display, and perform the touch operation without discomfort.

By providing the partitioning means on the operation pad, an excellent effect that the operation area can be clearly determined even by a blind touch can be obtained.
