[0002]
[Prior art]
Currently, in-vehicle devices equipped with various functions such as navigation, television, and audio are widely used. Such an in-vehicle device is provided with an operation button for selecting a function. However, due to the diversification of functions in recent years, when an uneven button is used, a plurality of buttons are used to call a desired function. It has become necessary to press in combination. For this reason, although the apparatus provided with the touch panel has increased in recent years, there has been a problem that the touch panel has a less operational feeling than the buttons with unevenness.
[0003]
Therefore, in recent years, when a switch displayed on the touch panel display is selected, the content of the function corresponding to the switch and the ON / OFF state are guided by voice, or the voice is recognized and displayed according to the recognized voice. There has been invented an automobile input device that switches screens or blinks and displays an icon of a selected switch (for example, see Patent Document 1).

[0027]
FIG. 2 is a flowchart showing a screen display control process executed by the in-vehicle device 1. As shown in the figure, in the screen display control process, when an operation input is made via the touch panel 12a (step S1; YES), the process proceeds to step S5. On the other hand, when there is no operation input (step S1; NO), it is determined whether time t2 has elapsed since the previous operation input (step S2). If the time t2 has not elapsed (step S2; NO), the process returns to step S1, and if the time t2 has elapsed (step S2; YES), the image is an explanatory image corresponding to the currently selected operation button. The moving image is read from the storage device 14 and displayed on the display unit 12b (step S3). Here, for example, when the MD is currently selected, a moving image corresponding to the MD is read from the storage device 14 and displayed.
[0028]
Subsequent to step S3, when an operation input is made via the touch panel 12a (step S4; YES), the process proceeds to step S5. In step S5, when any one of the operation buttons displayed on the display unit 12b is continuously pressed for the time t1 or more (step S5; YES), an explanatory image of the pressed operation button is read from the storage device 14.

[0032]
On the other hand, in step S8, it is determined that the pressed operation button is not the SRC button (step S8; NO), and when it is determined that the button is a volume changing button (step S12; YES), when the volume is changed. An explanatory image for use is read from the storage device 14 and displayed on the display unit 12b (step S13).
[0033]
FIGS. 5A to 5F show transition examples of the display screen in step S13. First, in the screen example shown in FIG. 5A, volume up buttons 103R and 103L for increasing the volume and volume down buttons 104R and 104L for decreasing the volume are displayed. When is pressed, the screen display sequentially changes to FIGS. 5B, 5C, 5D, and 5E. In FIGS. 5B to 5E, an image showing the volume value set by pressing the operation button is displayed large in the center of the screen, and a circular broken line is sequentially lit around the value. Is displayed, the screen returns to the same screen display as in FIG. 5A as shown in FIG.
Note that the display mode of the image G203 may be accompanied by not only a change in motion but also a change in color and brightness.
[0034]
Next, when the image display in step S13 ends (step S14; YES), the screen display control process ends.
[0035]
On the other hand, if it is determined in step S12 that the operated button is not a volume change button (step S12; NO) and it is determined that the button is a screen switching button (step S15; YES), the screen The switching image is read from the storage device 14 and displayed on the display unit 12b (step S16). Next, when it is determined that the display of the screen switching image has been completed (step S16; YES), for example, as shown in FIG. 6F, the next screen is displayed on the display unit 12b (step S18). The display control process ends.
[0036]
6A to 6F show transition examples of display screens in steps S16 to S18. In FIG. 6A, when the speaker mark 105, which is an operation button for setting the speaker, is pressed, the screen display changes to FIGS. 6B, 6C, 6D, and 6E. And change sequentially. As shown in FIGS. 6B to 6E, an explanatory image for screen switching (for example, a lightning-like image) is displayed with a change in movement (size or shape).
[0037]
Then, after the display of the screen switching image is completed, the next screen shown in FIG. 6 (f) (shown in FIG. 6 is a speaker setting screen) is displayed on the display unit 12b. As shown in the figure, a home mark 106 which is an operation button for returning to the original screen display is displayed on the speaker setting screen. When the home mark 106 is pressed on this screen, the screen switching explanatory images shown in FIGS. 6B to 6E are displayed along with the movement change, and then the screen shown in FIG. The original screen shown in Fig. 6 is displayed.
[0038]
Note that the screen switching images shown in FIGS. 6B to 6E may be displayed not only with changes in motion but also with changes in color and brightness.
[0039]
As described above, in the in-vehicle device 1, when the operation button is pressed via the touch panel 12a, an explanation image of the operation button is displayed on the display unit 12b according to the type of the pressed operation button or the continuous pressing time. Is displayed for a predetermined time. Further, when pressing of the operation button is not detected for a predetermined time or longer, an explanation image of the contents explaining the selected source (description image corresponding to the operation button) is displayed until the next operation input is made. . The explanatory image is dynamically displayed with changes in size, shape, color, brightness, and the like.
[0040]
Therefore, for example, when the volume is changed, the volume value after the change is dynamically displayed, the contents explaining the currently selected source are displayed with moving characters, and the pressed operation button is dynamically displayed. It becomes possible. For this reason, since the operation button pressed on the touch panel 12a and the currently selected function can be displayed in a visually easy-to-understand manner, it is possible to increase the operation feeling of the touch panel, which has been conventionally scarce. Thereby, the user can confirm the selected function reliably. Further, the user can easily confirm the selected function only by confirming the movement of the image or the change of the color with his / her eye without looking at the display screen of the display unit 12b.
[0041]
The present invention is not limited to the above embodiment. For example, the correspondence between the operation buttons and the explanation images may be configured to be different from the above embodiment. For example, the screen switching image G204 shown in FIG. 6 can be displayed instead of the source switching image G202 shown in FIG.
[0042]
In addition, in FIG. 4A, the example in which the SRC button 102 is displayed with a motion that vibrates left and right and up and down has been described, but the display mode when the operation button is pressed is not limited to this. For example, not only the pressed operation button can be displayed with movement, but also the color and shape of the operation button can be changed and displayed.
[0043]
Further, in the above embodiment, when the operation button is pressed, not only the explanation image is displayed, but also the beep sound and the guidance voice associated with each explanation image are outputted from the voice output unit 19. It is good as well.
[0044]
In addition, the detailed configuration and detailed operation of the in-vehicle device 1 to which the present invention is applied can be appropriately changed without departing from the spirit of the present invention.
[0045]
