Send. Examples of the external device 12 include a car navigation device, an air conditioner, a CD player, and a television.
[0015]
The switch management unit 6 includes a hardware switch control unit 13 and a software switch control unit 14.
The hardware switch 4 is configured by a push button switch or the like disposed around the screen display unit 2 and is provided for each external device 12.
The touch switch 3 is incorporated in the screen display unit 2. The screen display unit 2 is configured by a liquid crystal screen of a touch panel.
[0016]
The hardware switch control unit 13 is connected to the hardware switch 4 and transmits the open / closed state of the hardware switch 4 to the drawing unit 5.
The software switch control unit 14 is connected to the touch switch 3 and transmits the operation state of the touch switch 3 to the drawing unit 5.
The software switch control unit 14 includes a shortcut switch control unit 15. The shortcut switch control unit 15 includes a category classification table 16 and a display management table 17.
[0017]
The display device 1 includes a shortcut DB 7. The external device 12 includes a drawing DB 18. Note that the other functions of the external device 12 are not shown.
FIG. 2A shows the structure of the shortcut DB 7. Here, the number, display information on the screen, and registration information are stored for each registered shortcut object.
[0018]
The display information includes a display position, a display size, and display contents. Display contents include display color and display characters.
Examples of the registration information include information regarding the corresponding external device, object ID, and object type (operation information, operation switch).
[0019]
FIG. 2B shows the structure of the drawing DB 18. Here, for each object that the external device 12 has, its ID number, registration state, operation content, and display information are stored.
As the registration state, whether or not the object is stored in the shortcut DB 7 as a shortcut object is stored.
[0020]
As the operation content, the function is stored when the object is an operation switch, and the display content is stored when the object is operation information.
As the display contents, whether or not registration is possible for a shortcut, the display size of the object, and the like are stored. When the display sizes are different, the display characters can be easily displayed by changing the contents of the display characters.
[0021]
  FIG. 3 shows a screen displayed on the screen display unit 2.
  The user operates the hardware switch 4 to select a desired external device 12 to be displayed on the screen display unit 2. As a result, data is transmitted and received between the external device management unit 9 and the external device 12, and the screen management unit 8 causes the screen display unit 2 to send the external device 12Is displayed.
[0022]
In the illustrated example, the selected external device 12 is a car navigation system, and a map, a cursor 21 indicating the vehicle position, and guidance information 22 are displayed on a car navigation screen 19 (base screen). The car navigation device performs an operation according to a command by the user's voice and transmits operation information to the display device 1.
[0023]
The screen management unit 8 displays an object of an arbitrary external device registered in advance in the shortcut DB 7 so as to overlap the car navigation screen 19.
In the illustrated example, an object of the CD device is displayed, the magazine number and track number of the disc being played are displayed as the operation information 23, and “RAND (random)” and “fast forward” are displayed as the touch switch 24. It is displayed.
[0024]
The CD device objects 23 and 24 displayed on the screen operate as shortcut objects for the CD device. That is, with the car navigation screen 19 displayed, the performance state for the CD player can be confirmed by the shortcut operation information 23. Further, the CD player can be operated by the shortcut touch switch 24.
[0025]
When the user touches the shortcut touch switch 24, information on the shortcut object touched to the CD device of the external device 12 is sent from the software switch control unit 14 via the external device management unit 9.
In the CD device, a function corresponding to the received shortcut object information is operated, and the operation information is transmitted to the display device 1. This operation information is displayed on the screen display unit 2 by the screen management unit 8.
[0026]
Thus, the user can know the operation information of the CD device and perform a desired operation even when the screen of the navigation device is displayed on the display device. Therefore, when it is desired to operate the CD device as in the prior art, it is not necessary to switch to the CD screen or operate the remote control for the CD device, and the operability is improved.
[0027]
The shortcut objects 23 and 24 of the arbitrary external device 12 are registered in advance in the shortcut DB 7 by a user operation. The object registration method will be described below.
FIG. 4 is a flowchart showing the object registration process.
When there is an object to be registered as a shortcut key, the user selects an external device having the object by operating the hardware switch 4.
[0028]
This operation is detected by the hardware switch control unit 13, and the external device management unit 9 requests the corresponding external device to transmit screen data.
On the other hand, the selected external device extracts predetermined screen data from the drawing DB 18 and transmits it.
A screen created based on the screen data received by the external device management unit 9 is displayed on the screen display unit 2 by the screen management unit 8 (step S1).
[0029]
FIG. 5 shows a screen displayed on the screen display unit 2. This screen display processing is the same as the conventional screen display. Here, operation information 23 and a touch switch 24 are displayed as objects. In the figure, although only STATUS and SW are shown, the names corresponding to the functions of the external device 12 are actually shown.
[0030]
In a state where the normal screen is displayed, a shortcut menu screen is displayed by long pressing an arbitrary portion of the screen (step S2). The method for displaying the shortcut menu screen can be any method other than long-pressing the screen.
[0031]
FIG. 6 shows a shortcut menu screen 25.
Here, “Register”, “Delete”, “Resize”, and “Move” are displayed as shortcut menus.
When “registration” is selected (touching the corresponding part), a request is made to transmit information on an object that can be registered in the corresponding external device (step S3).
[0032]
In response to this, the external device refers to the drawing DB 18 and transmits information (number, position (coordinate), size), etc., of objects that can be registered (step S4).
The drawing unit 8 highlights what can be registered as a shortcut object in the screen of FIG. For example, a portion other than a registerable object is masked and displayed.
[0033]
The user selects an object to be registered (step S6). Then, information on the selected object is notified to the corresponding external device (step S7). Here, when the user touches the touch switch 3, it is checked whether or not the coordinates of the touched position indicate the position of an object that can be registered. If the position can be registered, the touched area information is transmitted from the software switch control unit 14 to the drawing unit 5.
[0034]
The object information that the drawing unit 5 transmits to the external device may be only the coordinates of the object. Alternatively, the ID of the object can be transmitted with reference to the shortcut DB 7.
In the external device, the notified information is provisionally registered in the drawing DB 18 (step S8), and the temporarily registered data is returned (step S9).
[0035]
The screen management unit 8 determines whether the selected object can be registered (step S10). Here, it is determined whether or not the object selected this time can be displayed on the screen when the object has already been registered. If registration is impossible here, the processing of FIG. 4 is terminated.
[0036]
If registration is possible, a request for main registration is notified to the corresponding external device 12 (step S11).
The external device 12 registers the temporarily registered object in its own drawing DB 18 (step S12). After this registration, a registration response is returned to the display device 1 (step S13). The registration response includes necessary information such as an object ID, a registration state, and operation content.
[0037]
If there is a registration response, the screen management unit 8 stores the shortcut object information in the shortcut DB 7 (step S14), and ends the object registration process of FIG.
Thereafter, as shown in FIG. 3, the display device 1 displays the screen (base screen) of an arbitrary external device 12 selected by the user, but the screen management unit 8 registers it in the DB 7 on the base screen. The shortcut objects 23 and 24 thus displayed are displayed.
[0038]
At this time, the screen management unit 8 compares either the display position of the object on the base screen or the display position of the already registered shortcut object with the display position of the shortcut object to be registered. The display position of the shortcut object to be registered is automatically changed to a position that does not overlap.
[0039]
Further, if there is no position that does not overlap, the external device is requested for a shortcut object having a smaller size. The external device refers to the drawing DB 18 and transmits a smaller size object and its display content.
In addition to requesting a shortcut object of a small size, all the registered objects are rearranged and displayed.
[0040]
The registered shortcut object can be switched between display and non-display by user selection. For this reason, one of the hardware switches 4 is a dedicated switch.
When the user operates this dedicated hardware switch, the hardware switch control unit 13 detects this and notifies the screen management unit 8. The screen management unit 8 switches between displaying and hiding the shortcut object each time an operation is detected.
[0041]
The shortcut object can be displayed or hidden automatically. For example, when the connection with the external device is disconnected, the shortcut DB 7 is referred to, and when the shortcut object of the disconnected external device is registered, the registration is deleted. As a result, the shortcut object is switched from display to non-display.
[0042]
When the shortcut touch switch 24 displayed on the screen display unit 2 is operated (touched on the screen), the corresponding external device 12 operates a function corresponding to the operation.
Processing when the shortcut touch switch is operated will be described with reference to the flowchart of FIG.
[0043]
As shown in FIG. 3, a desired touch switch 24 is operated in a state where the shortcut objects 23 and 24 are displayed on the normal screen (step S21). Then, the ID corresponding to the coordinate of the operated touch switch 24 is extracted from the shortcut DB 7 and notified to the corresponding external device 12 (step S22).
[0044]
The external device 12 refers to the drawing DB 18 to collate the received ID with the function of its own device (step S23) and activate the function (step S24).
Thereafter, the operation information is transmitted to the display device 1 and displayed on the screen display unit 2. This point is executed by a function provided conventionally.
[0045]
Registered objects can be deleted.
The deletion process will be described with reference to the flowchart of FIG.
As shown in FIG. 3, an arbitrary normal screen and shortcut objects are displayed on the screen display unit 2. In a state where the normal screen is displayed, a shortcut menu screen (FIG. 6) is displayed by long-pressing an arbitrary portion of the screen (step S31).
[0046]
If “delete” is selected here, the screen returns to the screen of FIG. When the user selects an object to be deleted (step S32), the corresponding external device 12 is determined by searching the shortcut DB 7 based on the touched coordinates. Then, the corresponding external device 12 is notified of information on the object to be deleted (step S33).
[0047]
The external device 12 changes the registered state in the drawing DB 18 to deleted for the notified object (step S34). Then, a deletion completion notification is returned to the display device 1 (step S35).
The screen management unit 8 deletes the notified shortcut object from the shortcut DB 7 (step S36). Thereafter, the deleted object is not displayed on the screen display unit 2.
[0048]
When there is a specification change in the external device 12, the display device 1 is automatically notified and the display is changed.
A process performed by changing the external device 12 will be described with reference to the flowchart of FIG. When the object information in the drawing DB 18 changes (step S41), the external device 12 automatically notifies the display device 1 of the changed object information (step S42).
[0049]
When the screen management unit 8 receives the notification of the object information, it collates with the shortcut DB 7, and when it is determined that the registered shortcut object has changed, the corresponding shortcut object is updated (step S43). ).
By doing so, the shortcut object can be changed without any particular operation by the user.
[0050]
According to the processing described above, the shortcut object is displayed in an initially set size. When there is a request that this size is too large or too small, the size of the object can be changed.
The size change process will be described with reference to the flowchart of FIG.
A shortcut menu screen (FIG. 6) is displayed by long pressing an arbitrary portion of the screen of the screen display unit 2 (step S61).
[0051]
When “size change” is selected (step S62), the external device 12 is requested to change the size pattern (step S63).
The external device 12 transmits a plurality of object sizes prepared in the drawing DB 18 in response to the request (step S64).
[0052]
The screen management unit 8 displays a screen for changing the size (step S65).
FIG. 11 shows a screen for changing the size. In the illustrated example, three types of sizes of large (L), medium (M), and small (S) are prepared as object sizes. Further, the currently used size (M) is displayed by shading. When the user selects a desired size (step S66), a size change request is requested from the corresponding external device 12 (step S67).
[0053]
The external device 12 updates the size in the registration state of the drawing DB 18 (step S68), and notifies the change completion (step S69). The screen management unit 8 changes the display size in the shortcut DB 7 (step S70). Thereby, the display size of the object displayed on the screen display part 2 is changed (step S71).
[0054]
The shortcut object described above is described as being registered for one external device 12. However, the shortcut object can be registered for a plurality of external devices 12 at the same time.
For this purpose, the registration process described with reference to FIG. 4 may be performed for a plurality of external devices 12.
[0055]
As a result, the number of registered objects increases, and if all objects are displayed on one screen display unit 2, the screen may be difficult to see. In this case, it is possible to make the screen easier to view by reducing the number of objects displayed on one screen by displaying the registered objects in categories.
[0056]
The flowchart of FIG. 12 shows the process in the case of automatically classifying categories. When the shortcut object registration process ends (step S81), the classification of the registered shortcut object is determined (step S82).
As a result, it is determined whether or not the target category exists in the category classification table 16 (step S83). If it exists, the shortcut object is registered in the determined category of the display management table 17 (step S84).
[0057]
If “No” in step S83, it is determined whether or not the user designates a classification category (step S91). If user designation is selected here, a registration category is selected by a user operation (step S92), and the shortcut object is registered in the selected category of the display management table (step S94).
If No in step S91, the default category is selected (step S93), and the shortcut object is registered in the default category of the display management table 17 (step S94).
[0058]
After registration in the display management table 17, it is determined whether display category selection is user selection (step S85) or base screen selection (step S86). If the user is selected (Yes in step S85), the display category is selected by the user's selection operation (step S87), and the shortcut object belonging to the display category is selected from the display management table 17 and displayed (step S90). .
[0059]
If it is base screen selection (Yes in step S86), the display category corresponding to the base screen is selected from the display management table 17 (step S88), and objects belonging to the display category are selected from the management table and displayed (step S88). S90).
If neither step S85 nor step S86 is selected, a display category is selected from the display management table 17 in accordance with an instruction from the external device 12 corresponding to the registered object (step S89), and objects belonging to the display category are displayed from the display management table 17. Selected and displayed (step S90).
[0060]
The flowchart in FIG. 13 shows processing when a user classifies a category. When the registration process ends (step S101), the user designates the registered shortcut object classification (step S102).
Next, it is determined whether or not the category designated for classification is a new category (step S103). If it is not new (No in step S103), the shortcut object is registered in the designated category of the display management table 17 (step S104).
[0061]
If Yes in step S103, the category name is input by the user (step S105), and it is checked whether the category name is duplicated (step S106). If the category name is duplicated, the process returns to step S105 and input again. Make it. If not overlapping, a new category is added to the display management table 17 (step S107), and the shortcut object is registered in the new registration category of the display management table 17 (step S104).
Next, a display category is selected. Since the following processing is the same as that in FIG. 11 described above, the same number of steps is used, and redundant description is omitted.
[0062]
The flowchart in FIG. 14 shows processing when a category is classified by designation of an external device.
When the registration process ends (step S121), classification of the registered shortcut object is performed by the external device 12 (step S122).
Next, it is determined whether or not the designated category is a new category (step S123). If it is not new, it is registered in the designated category of the display management table 17 (step S124).
[0063]
If Yes in step S123, the designated category is registered in the display management table 17 (step S125), and the shortcut object is registered in the newly registered category of the display management table 17 (step S124).
Next, a display category is selected. Since the following processing is the same as that in FIG. 11 described above, the same number of steps is used, and redundant description is omitted.
