[0008] The present invention will be described below based on the illustrated embodiments, but the present invention is not limited to the embodiments described below.

[0009] Figure 1 shows a home screen HS1 displayed on a touch-panel automotive display installed inside the cabin of a car. This automotive display is a horizontally elongated rectangle with an upper side FU, a lower side FB, a left side FL, and a right side FR.

[0010] The home screen HS1 has three simplified display areas S11, S12, and S13, each of which is substantially rectangular and has substantially the same size. The vertical dimensions of areas S11, S12, and S13 are approximately the same as the vertical dimension of the home screen HS1. The horizontal dimension W11 of area S11, the horizontal dimension W12 of area S12, and the horizontal dimension W13 of area S13 are also approximately the same. The left side of area S11 is spaced apart from the left side FL of the automotive display. The right side of area S11 is adjacent to the left side of area S12, and the right side of area S12 is adjacent to the left side of area S13. The right side of area S13 is adjacent to the right side FR of the automotive display.

[0011] Area S11 is an area where a menu of media functions for displaying and operating media such as audio and radio is displayed. Area S12 is an area where a menu of telephone functions is displayed, such as a keypad for making calls and a history of incoming and outgoing calls. Area S13 is an area where a menu of car navigation functions such as the current position of the car and the route to the destination is displayed. A switching button S11a is displayed in the upper right corner of area S11. When this switching button S11a is pressed, the screen switches to a detailed display screen for the media function. Similarly, a switching button S12a for switching to a detailed display screen for the telephone function is displayed in the upper right corner of area S12, and a switching button S13a for switching to a detailed display screen for the car navigation function is displayed in the upper right corner of area S13. The detailed display screen will be described later.

[0012] The home screen HS1 also displays five roughly square buttons B14 to B18 of roughly the same dimensions. These five buttons can be collectively referred to as a first button group. The five buttons B14 to B18 are lined up in order from top to bottom of the screen with no gaps between them. The top side of button B14 is in contact with the top side FU of the car display, and the bottom side of button B18 is in contact with the bottom side FB of the car display. The left sides of each of the five buttons B14 to B18 are in contact with the left side FL of the car display. The right sides of each of the five buttons B14 to B18 are in contact with the left side of area S11.

[0013] When the button B14 labeled "Mode" is pressed, a separate screen for switching the vehicle's driving mode is displayed. For example, there are a mode that assists stability while driving, a mode that maintains high engine speed suitable for driving on mountain roads or merging at high speeds, a mode that optimizes driving force on snowy roads, and a mode that distributes driving force to the wheels with grip when escaping mud. When the button B15 labeled "Car Info" is pressed, a separate screen for the information confirmation function is displayed, which allows the driver to check the mileage, cruising range, average fuel consumption, instantaneous fuel consumption, average vehicle speed, and the like. When the button B16 labeled "Assist" is pressed, a separate screen for the ADAS (Advanced Driver Assistance System) function will be displayed, allowing you to turn the function on or off and check the currently active ADAS functions. When the button B17 labeled "Help" is pressed, an individual screen for a function that provides guidance on difficult-to-understand operation methods or setting contents is displayed. When the button B18 labeled "Setting" is pressed, a menu screen for making various settings is displayed.

[0014] When button B15 on the home screen HS1 shown in Fig. 1 is pressed, the screen switches to individual screen KS1 shown in Fig. 2. On individual screen KS1, buttons B14 to B18 are displayed, similar to home screen HS1. On individual screen KS1, a detailed display area D14, which occupies the majority of the screen, and four buttons BH, B11, B12, and B13 are also displayed.

[0015] The detail display area D14 is a generally horizontally elongated rectangle, with its top and bottom edges touching the top and bottom edges FU and FB of the automotive display, respectively. The right edges of the five buttons B14 to B18 touch the left edge of the detail display area D14. The right edge of the detail display area D14 is spaced apart from the right edge FR of the automotive display.

[0016] Buttons BH, B11, B12, and B13 are lined up in order from top to bottom of the screen with no gaps between them. Button BH is a roughly vertically elongated rectangle with its top edge touching the top edge FU of the automotive display, its left edge touching the right edge of the detail display area D14, and its right edge touching the right edge FR of the automotive display. The three buttons B11, B12, and B13 are all roughly square and have the same dimensions. Their left sides are in contact with the right side of the detail display area D14, and their right sides are in contact with the right side FR of the automotive display. The vertical dimension H11 of button B11, the vertical dimension H12 of button B12, and the vertical dimension H13 of button B13 are all approximately the same.

[0017] The three buttons B11 to B13 can be collectively called a second button group.

[0018] When the button BH labeled "Home" is pressed, the screen switches to the home screen HS1 shown in Figure 1. When the button B11 labeled "Media" is pressed, the screen switches to a menu screen for displaying and operating media such as audio and radio. When the button B12 labeled "Phone" is pressed, the screen switches to a menu screen for the telephone function. When the button B13 labeled "Navi" is pressed, the screen switches to a menu screen for the car navigation function, which displays the current position of the car and the route to the destination.

[0019] Thus, area S11 in Fig. 1 and button B11 in Fig. 2 correspond to the media function, area S12 in Fig. 1 and button B12 in Fig. 2 correspond to the telephone function, and area S13 in Fig. 1 and button B13 in Fig. 2 correspond to the car navigation function. In Fig. 1, areas S11, S12, and S13 have a width ratio of 1:1:1, and correspondingly, in Fig. 2, buttons B11, B12, and B13 have a height ratio of 1:1:1.

[0020] When the switching button S13a shown in Fig. 1 or the button B13 shown in Fig. 2 is pressed, the screen switches to the individual screen KS2 shown in Fig. 3. On the individual screen KS2, buttons BH and B11 to B18 are displayed, similar to the individual screen KS1 shown in Fig. 2. Furthermore, instead of the area D14 on the individual screen KS1 shown in Fig. 2, an area D23 is displayed on the individual screen KS2 in Fig. 3. This area D23 is a detailed display area for the car navigation function.

[0021] FIG. 4 shows another home screen HS2. Similar to the home screen HS1 shown in FIG. 1, the home screen HS2 displays an area S13 and buttons B14 to B18. Meanwhile, instead of the areas S11 and S12 of the home screen HS1 shown in FIG. 1, a simplified display area S21 is displayed. This area S21 is rectangular, with its top and bottom edges touching the top and bottom edges FU and FB of the automotive display, respectively. The right edges of the buttons B14 to B18 touch the left edge of the area S21, and the right edge of the area S21 touches the left edge of the area S13. The horizontal dimension W21 of the area S21 is approximately twice the horizontal dimension W13 of the area S13. A switching button S21a is displayed in the upper right corner of the area S21.

[0022] When the button B18 on the home screen HS2 shown in Fig. 4 is pressed, the screen switches to the individual screen KS3 shown in Fig. 5. On the individual screen KS3, buttons B14 to B18 are displayed, similar to the home screen HS2. On the individual screen KS3, a home button BH and a button B13 are also displayed, similar to the individual screen KS1 shown in Fig. 2.

[0023] In addition, a horizontally elongated rectangular area D39 is displayed on the individual screen KS3 in place of area D14 in FIG. 2. This area D39 is an area for setting the home screen. Three icons D39a, D39b, and D39c are displayed in this area, from left to right. When icon D39a is pressed, the home screen is set to display three simplified display areas of the same size side by side. In other words, when icon D39a is pressed, the home screen layout is set to the layout setting similar to home HS1 shown in FIG. 1. When icon D39b is pressed, the home screen is set to display two simplified display areas of different sizes side by side, with the larger simplified display area displayed to the left of the smaller simplified display area. The outermost frame of icon D39b indicates that this setting is the current setting. When icon D39c is pressed, the home screen is set to display two simplified display areas of different sizes side by side, with the larger simplified display area displayed to the right of the smaller simplified display area.

[0024] The individual screen KS3 also displays a button B21 that is a substantially vertically elongated rectangle. The top side of this button B21 is in contact with the bottom side of the home button BH, the bottom side is in contact with the top side of the button B13, the left side is in contact with the right side of the area D39, and the right side is in contact with the right side FR of the automotive display.

[0025] Thus, area S21 in Fig. 4 and button B21 in Fig. 5 correspond to the media function, and area S13 in Fig. 4 and button B13 in Fig. 5 correspond to the car navigation function. In Fig. 4, areas S21 and S13 have a width ratio of 2:1, and correspondingly, in Fig. 5, buttons B21 and B13 have a height ratio of 2:1.

[0026] When icon D39c in FIG. 5 is pressed, the layout setting of the home screen is changed to that of home screen HS3 in FIG. 6. On home screen HS3, area S11 and buttons B14 to B18 are displayed, similar to home screen HS1 shown in FIG. 1. Meanwhile, simplified display area S33 is displayed in place of areas S12 and S13 of home screen HS1 shown in FIG. 1. This area S33 is rectangular, with its top and bottom edges bordering the top and bottom edges FU and FB of the automotive display, respectively. Furthermore, the left edge of area S33 borders the right edge of area S11, and its right edge borders the right edge FR of the automotive display. The horizontal dimension W33 of area S33 is approximately twice the horizontal dimension W11 of area S11. A switching button S33a is displayed in the upper right corner of area S33.

[0027] When button B15 on the home screen HS3 shown in FIG. 6 is pressed, the screen switches to individual screen KS4 shown in FIG. 7. On individual screen KS4, buttons B14 to B18, a detailed display area D14, and a home button BH are displayed, similar to the individual screen KS1 shown in FIG. 2. Furthermore, on individual screen KS4, buttons B43 and B41 are displayed instead of buttons B11 to B13 on individual screen KS1 shown in FIG. 2. Button B43 has a vertically elongated rectangular shape, with its top edge abutting the bottom edge of home button BH, its left edge abutting the right edge of area D14, and its right edge abutting the right edge FR of the automotive display. On button B41, its top edge abutting the bottom edge of button B43, its bottom edge abutting the bottom edge FB of the automotive display, its left edge abutting the right edge of area D14, and its right edge abutting the right edge FR of the automotive display. The height H43 of the button B43 is about twice the height H41 of the button B41.

[0028] Thus, area S33 in Fig. 6 and button B43 in Fig. 7 correspond to the car navigation function, and area S11 in Fig. 6 and button B41 in Fig. 7 correspond to the media function. In Fig. 6, areas S33 and S11 have a width ratio of 2:1, and correspondingly, in Fig. 7, buttons B43 and B41 have a height ratio of 2:1.

[0029] Alternatively, when the switching button S13a of the individual screen HS1 shown in FIG. 1 is pressed, the screen may be switched to the individual screen KS5 shown in FIG. 8 instead of the individual screen KS2 shown in FIG. 3. On the individual screen KS5, buttons BH, B12, and B14-B18 and area D23 are displayed, similar to the individual screen KS2 shown in FIG. 3. Furthermore, instead of buttons B11 and B13 shown in FIG. 3, buttons B53 and B51 are displayed. The top side of button B53 is in contact with the bottom side of button BH, the bottom side is in contact with the top side of button B12, the left side is in contact with the right side of area D23, and the right side is in contact with the right side FR of the automotive display. The top side of button B51 is in contact with the bottom side of button B12, the bottom side is in contact with the bottom side FB of the automotive display, the left side is in contact with the right side of area D23, and the right side is in contact with the right side FR of the automotive display.

[0030] Thus, area S11 in Fig. 1 and button B51 in Fig. 8 correspond to the media function, area S12 in Fig. 1 and button B12 in Fig. 8 correspond to the telephone function, and area S13 in Fig. 1 and button B53 in Fig. 8 correspond to the car navigation function. In Fig. 1, areas S13, S12, and S11 have a width ratio of 1:1:1, and correspondingly, in Fig. 8, buttons B53, B12, and B51 have a height ratio of 1:1:1.

[0031] 9 shows an example of the computer hardware configuration of the automotive display 1. The automotive display 1 includes a CPU 11, an interface device 12, a display device 13, an input device 14, a drive device 15, an auxiliary storage device 16, and a memory device 17, which are interconnected by a bus 18.

[0032] The program that realizes the functions of the automotive display 1 is provided by a recording medium 19 such as a CD-ROM. When the recording medium 19 on which the program is recorded is set in the drive device 15, the program is installed from the recording medium 19 into the auxiliary storage device 16 via the drive device 15. Alternatively, the program does not necessarily have to be installed from the recording medium 19, but can also be installed via a network. The auxiliary storage device 16 stores the installed program as well as necessary files, data, etc.

[0033] The memory device 17 reads out and stores the program from the auxiliary storage device 16 when an instruction to start the program is received. The CPU 11 realizes the functions of the automotive display 1 in accordance with the program stored in the memory device 17. The interface device 12 is used as an interface for connecting to other computers via a network. The display device 13 displays a GUI (Graphical User Interface) or the like according to the program. Examples of this GUI are as described with reference to FIGS. 1 to 8. The input device 14 is a touch panel or the like.

[0034] Fig. 10 shows an example of the software functional configuration of the automobile display 1. The automobile display 1 has an operation reception unit 21 that receives user operations, and a display control unit 22 that controls the display of the screen in accordance with the operations received by the operation reception unit 21. The screens shown in Figs. 1 to 8 are displayed in the display area of ​​the automobile display 1.

[0035] The above embodiment will be further described. (1a) The home screen is provided with buttons to allow users to move on to other operations, but because the home screen displays multiple simple display areas, the buttons are displayed along one of the top, bottom, left, or right edges to make the display as large as possible. (1b) You can move to individual screens by selecting the switch button on the home screen or by touching a button. (1c) Since an individual screen has only one detailed display area, buttons are displayed along two of the edges, either top, bottom, left, or right. (1d) At one of the two ends of (1c) above, a home button for returning to the home screen and buttons for functions corresponding to the simplified display area of ​​the home screen are displayed. When simplified display areas for functions A, B, and C are displayed on the home screen, the home button and buttons for functions A, B, and C are displayed at one end of the individual screen. (1e) Pressing the button will take you to the individual screen for that function. However, if the screens for functions A, B, and C are displayed on the home screen and you use the switch button for function A to transition to the individual screen for function A, pressing the button for function A will not change the display. Pressing the button for function B or C will take you to the individual screen accordingly. (1f) The height of the second button group on the individual screen is determined according to the area ratio of the simplified display area on the home screen. (1g) The simplified display area on the home screen and the detailed display area of ​​the same function are different in size, and therefore the number of sub-functions available for that function differs. For example, the audio function allows users to use sub-functions such as "play," "stop," "next," and "previous" in the simplified display area of ​​the home screen. In addition to the sub-functions available in the simplified display area of ​​the home screen, the individual audio function screen also allows users to use sub-functions such as shuffle and source switching. The air conditioning functions can be controlled by adjusting the temperature and airflow on the home screen. On the individual screen, the auto and off functions, seat heaters, etc. are also displayed and selectable. The phone function allows you to operate the call history on the home screen, and the keypad and phone book on individual screens. The car navigation function allows you to "Go home" and "Cancel route" on the home screen. On individual screens, you can also adjust the area, scale, and volume. (1h) The button position and the display content on the home screen can be changed by dragging and dropping after pressing and holding.

[0036] As described in (1a), by displaying the buttons only at one end, it is possible to make maximum use of the screen size on a home screen that has multiple screens, and it is also possible to easily transition to other functions. (1b) allows you to easily switch to an individual screen when necessary. Since you cannot switch to an individual screen without pressing the switch button from the home screen, you can simultaneously use multiple simple display areas displayed on the home screen. (1c) and (1d) allow easy movement from individual screens to the home screen, and allow transition to individual screens of screens displayed on the home screen that are likely to be used frequently. All the icons of the screens that were displayed on the home screen (1d) are displayed, and buttons are also displayed for the screens that are switched, so that it is easy to select individual screens. Furthermore, if the screens for functions A, B, and C are displayed on the home screen and the function A switch button is pressed to transition to the individual screen for function A, assuming that there is no icon for function A, the home screen can display multiple screens and the screen size can be changed (selected). Therefore, it can be difficult for users who are not familiar with the system to tell whether they have transitioned to the individual screen for function A or whether the simple display areas for functions B and C on the home screen are simply different sizes. (1f) allows you to understand the configuration of the home screen even on individual screens. Also, for home screens, there may be three screens with a screen size ratio of 1:1:1, or two screens with a screen size ratio of 2:1 or 1:2. In this case, the screens can be used more effectively when the number of screens is reduced from three to two. If the button size is 2:1, the home screen will also be 2:1. Therefore, the screen size ratio is 2:1, and the smaller screen corresponds to the car navigation function. If you want to use the car navigation function, you can return to the home screen, which is small, and press a button to go to the individual screen for the car navigation function. On the other hand, if the screen size ratio is 2:1 and the functions on the smaller screen can be easily operated without pressing the larger screen, you can operate the smaller screen by pressing the home button without pressing the button. Since you are already on the home screen, there is no need to press the home button to return to the home screen. When you want to move on to the next operation, you can visually check in advance whether the size of the simple display area on the home screen is sufficient or whether you need to switch to an individual screen. (1g) allows you to use the minimum necessary functions even with a small screen size. (1h) allows for improved visibility and operability according to user preferences.

[0037] By making the buttons appear only when you touch the touch panel or when your hand is close to the touch panel, the screen size can be made larger under normal circumstances (when your hand is not close to the panel). When a button for a function that has been switched to an individual screen for that function is touched, a message indicating that the screen has already been switched may be displayed, making it easier to recognize that the screen is not the home screen.

[0038] Regarding (1a) to (1h), unnecessary program processing is reduced as follows, and as a result, unnecessary calculations are not performed, thereby reducing the calculation load. -Easy transition to the home screen and individual screens - The difference between individual screens and the home screen can be easily seen, reducing accidental operations. - By knowing the size ratio of the home screen on each individual screen, you can visually determine whether the next screen to move to is the home screen or a settings screen for changing the screen size, reducing inadvertent operations. - The same icon as on the individual screen cannot be selected -Increasing the screen size reduces the chance of incorrect operation

[0039] (2a) The individual screen displays all the buttons that were displayed on the home screen and a home button that transitions to the home screen, and the size ratio of the buttons is the same as the size ratio of the simplified display areas that were displayed multiple times on the home screen. (2b) Functions can be operated on the home screen and individual screens. (2c) When you change the number of simple display areas on the home screen and the size of each area, the number and size of the buttons on each individual screen will automatically change accordingly. (2d) The button size ratio will be the same as the area ratio of the home screen. (2e) The button size ratio will be the same as the larger difference between the horizontal and vertical lengths of the home screen (if the height of the home screen changes). The (2f) button and the home button are located at the left and right ends, and their order is from top to bottom: home button, multiple buttons. The order of the multiple buttons from top to bottom is the same as the order of the multiple simple display areas displayed on the home screen from left to right. (2g) Individual function buttons and the home button are displayed on the driver's side. In right-hand drive vehicles, they are displayed on the right side of the display. (2h) The individual function buttons and the home button have the same horizontal size, but the size of the buttons varies depending on the height. (2i) On the individual screen, multiple buttons (first group of buttons) that transition to other functions are arranged in a vertical row, and are located on the opposite side from the icons (second group of buttons) and the home button. (2j) On the home screen, a switch button is provided in the upper right corner of each simple display area, and by selecting the switch button, it is possible to transition to an individual screen for the function of each screen. When transitioning from the home screen to an individual screen, the icon (second button group) related to that individual screen cannot be selected, but the remaining icons can be selected to transition to the individual screen of that icon. Of the three functions A, B, and C on the home screen, if you transition to the individual screen for function A, nothing happens when you press the button for function A on the individual screen for function A. However, touching the buttons for functions B and C will transition to the individual screens. (2k) One side, two opposing sides, or all sides of each simplified display area on the home screen are colored in a different color for each simplified display area (symbols CL1, CL2, and CL3 in FIG. 1), and the icons on individual screens display the colors associated with each simplified display area (symbols CL1, CL2, and CL3 in FIG. 2). The symbols CL1 to CL3 in FIG. 1 and the symbols CL1 to CL3 in FIG. 2 indicate that the display colors are the same. (2l) The multiple screens and buttons on the home screen all have separate functions.

[0040] (2a) allows the user to grasp the configuration of the home screen even on individual screens. (2b) The icon ratio gives you an idea of ​​the screen size of the home screen, so you can immediately understand whether to go to the home screen or an individual screen for the function you want to operate. If the icon size is 2:1, the home screen will also be 2:1. (2c) The user can select the size and number of home screens, and when these are changed, the user does not need to reset the individual screens, which can be expected to have the effect of (2a) above. (2d) It is easy to grasp the sense of size. If the height of each home screen size is the same, the ratio of the horizontal lengths will be the ratio of the icon size. Therefore, by fixing the width of the icon and changing the vertical ratio, it is possible to make it easier to grasp the sense of size even when expressing the ratio. (2e) The larger the aspect ratio, the greater the visual change, making it easier to understand when displayed as an icon. If you fix the width when arranging icons vertically, the ratio of the home screen will be expressed in terms of the vertical width, but since the icons are expressed in terms of the ratio of one vertical side, and the home screen is also expressed in terms of the ratio of one vertical side to one horizontal side, it is easy to get a sense of the size. (2f) The home button is used frequently, so by displaying it at the top, it is easier to see and operate. In addition, since horizontal text is generally read from left to right and vertical text is read from top to bottom, the relative positions of the home screens can be easily understood when icons are displayed. (2g) The home button is frequently used and is easy to operate while driving, so placing it on the driver's side will improve convenience. Since it is easier to understand if the position of the first button group does not change between the home screen and individual screens, the second button group and the home button are placed on the opposite side of the first button group. (2h) By changing the icon ratio, you can prevent the display of individual screens from becoming too small. It is possible to prevent the display of individual screens from becoming smaller by fixing the width of the larger icon and reducing the width of the smaller icon, but this eliminates the disadvantage that visibility and operability are poor when the icon is small. (2i) Placing the first button group and the second button group close to each other increases the possibility of operational errors, but this possibility can be eliminated. By displaying the first button group and the home button and second button group separately on both sides, the detailed display area of ​​the individual screen can be positioned in the center, resulting in a better appearance. When the display is landscape, arranging the display along the top and bottom edges makes the detailed display area appear more compressed and looks less appealing, but this can be avoided. (2j) You can switch functions on the home screen. When operating on a screen, it is generally easier to understand if the operation buttons are displayed at the bottom and the letters or figures representing them at the top, but this reduces the chance of accidentally pressing the switch button when operating and does not get in the way. When operating a touch panel, you may move your hand downwards for navigation, etc., and you may also move your hand upwards, but you rarely move your fingers all the way to the top, which reduces the chance of accidentally pressing the switch button. Selecting an icon after switching home screens is a mistake, so you can avoid changing the display unnecessarily at that time. By pressing the icon, you can display a message that it is an error or take you back to the individual screen for that icon, but doing so will prevent you from operating the device during that time, resulting in wasted time, and this can be prevented. (2k) By linking icons to the home screen not only by displaying the text and pictures on the icons but also by coloring them, it becomes easier to understand what the icons represent. (2l) On individual screens, home screen functions can be selected as icons, allowing you to display as many functions as possible and transition between them by selecting them.

[0041] The number of screens displayed on the home screen is limited, and if the number of screens set as home screens is reduced, the functions of the screens that will no longer be displayed on the home screen next time may be automatically displayed as buttons. This saves the user the trouble of having to reconfigure frequently used or likely used home screen functions as buttons.

[0042] Regarding (2a) to (2l), unnecessary program processing is reduced as follows, and as a result, unnecessary calculations are not performed, thereby reducing the calculation load. - By knowing the size ratio of the home screen on each individual screen, you can visually determine whether the next screen to move to is the home screen or a settings screen for changing the screen size, reducing inadvertent operations. · No need to reconfigure individual screens when changing the size or number of home screens - Reducing accidental operation by appropriately positioning and sizing buttons

[0043] The following additional notes are provided regarding the above-described embodiments. [Appendix 1] 1. An automotive display that allows multiple functions to be used and that can be switched between a home screen and an individual screen, the plurality of functions includes a first group of functions and a second group of functions; a first button group including a plurality of buttons corresponding to a plurality of functions included in the first function group is displayed on the home screen, and when one of the plurality of buttons included in the first button group is operated, the screen switches to the individual screen having a detailed display area for the function corresponding to the operated button; a plurality of simplified display areas respectively corresponding to a plurality of functions included in the second function group are displayed on the home screen, and a switching button for switching to the individual screen having a detailed display area for the corresponding function is displayed in each of the simplified display areas; the individual screen displays the details display area, a home button for switching to the home screen, the first button group, and a second button group including a plurality of buttons respectively corresponding to a plurality of functions included in the second function group, and when any of the plurality of buttons included in the second button group is operated, the screen switches to the individual screen having a details display area for the function corresponding to the button; the number and size of the plurality of simplified display areas displayed on the home screen and the functions corresponding to each simplified display area can be selectively designated; The ratio of the sizes of the plurality of buttons included in the second button group displayed on the individual screen is the same as the ratio of the sizes of the plurality of simplified display areas displayed on the home screen. Automotive display. [Effects of Appendix 1] On each screen, you can see the layout and screen ratio of the home screen. The buttons make it easy to get a sense of the screen size of the home screen. Even on individual screens, it is possible to recognize whether it is better to change the size or type of the home screen, making it easy to choose whether to return to the home screen or move on to another individual screen. This eliminates the need to operate the individual screen when the home screen configuration cannot be recognized. If the heights of the simplified display areas on the home screen are the same, the ratio of the widths of the simplified display areas will be equal to the ratio of the button sizes. Therefore, by fixing the button width, when the buttons are arranged vertically, the ratio of the button heights can be changed according to the width of each simplified display area. In other words, the size of the simplified display area on the home screen can be intuitively grasped from the ratio of the button heights on individual screens. Furthermore, since there is no need to change the button width, the width of the detailed display area on each individual screen can be secured. [Appendix 2] the second button group is arranged in the vertical direction along the left or right side of the automotive display, the widths of the plurality of buttons included in the second button group are predetermined, A ratio of heights of the plurality of buttons included in the second button group is determined according to an area ratio of the plurality of simplified display areas displayed on the home screen. 10. An automotive display as described in Appendix 1. [Effects of Appendix 2] The size of each button included in the second button group can be changed while ensuring the width of the detail display area of ​​the individual screen. Changing the width of a button can potentially reduce the width of the detail display area on an individual screen, but this can be avoided. This ensures the width of the detail display area on an individual screen while increasing the user's visibility of the button, thereby maintaining the functionality of the individual screen while improving the user's convenience for the button. It is possible to prevent the display of individual screens from becoming smaller by fixing the width of relatively large buttons and reducing the width of relatively small buttons, but since small buttons have poor visibility and operability, this can eliminate such disadvantages. A relatively large button or a button located at the top of an individual screen is defined as a first button. A relatively small button or a button located below the first button is defined as a second button. If there are three or more buttons in the second button group, they are defined as the first button, second button, third button, and so on. The buttons are arranged vertically along the left or right side of the screen in descending order of area, with the first button being the first, the second button being the second, and the third button being the third. Furthermore, the buttons are arranged from top to bottom of the screen in the order of the first button, the second button, and the third button. [Appendix 3] 3. The automotive display according to claim 1, wherein when the size or number of the simplified display areas on the home screen is changed, the area ratio or number of the buttons on the individual screen is changed. [Effects of Appendix 3] The home screen allows the user to select the size and number of simplified display areas, but when these are changed, the user does not need to reconfigure the individual screens, and the aforementioned effects can still be expected. [Appendix 4] a switching button for switching to an individual screen of a function corresponding to each simplified display area is displayed in the upper right corner of each simplified display area on the home screen; 4. The automotive display according to claim 1, wherein functions included in the second function group are available on each of the home screen and the individual screen. [Effects of Appendix 4] The button ratio gives an intuitive sense of the size of the home screen, allowing users to quickly determine whether to switch to the home screen or an individual screen for the function they want to use. If the size of the two buttons is 2:1, the size of the simple display area on the home screen will also be 2:1. Therefore, if the simplified display area with a relatively small size is a car navigation function, when returning to the home screen, the size is small, and it is possible to switch to a relatively large individual screen by operating a button. Furthermore, if a function can be easily used without a large screen, the function can be used on a small home screen by pressing the home button instead of the button corresponding to the function. After using the function, since it is the home screen, there is no need to operate the home button again to return to the home screen, which is convenient. In other words, when you want to move on to using the next function, you can visually determine on the current individual screen whether the size of the simplified display area displayed on the home screen is sufficient or whether you need to proceed to an individual screen. When operating on a screen, it is generally easier to understand if letters or figures indicating the function of the operation button are displayed above the screen, but this reduces the possibility of accidentally pressing the switch button when operating and does not get in the way. When operating a touch panel, you may move your hand downwards for navigation, etc., and you may also move your hand upwards, but you rarely move your fingers all the way to the top, which reduces the chance of accidentally pressing the switch button. For example, when it comes to audio functions, it is easier to understand if buttons such as play, stop, next, and previous are displayed at the bottom and audio-related figures are displayed at the top than if the buttons are at the top and the figures are at the bottom. Because the button is located at the bottom, there is less chance of accidentally pressing the magnification button (switch button) in the upper corner when operating the button. When navigating, there is less chance of moving your finger until it touches the magnification button (switch button) in the upper corner, so there is less chance of accidentally pressing the magnification button when trying to perform another operation.
