It is supplied to the unit 24. The control unit 24 calculates the current position and direction of the vehicle based on these output signals. When displaying road guidance around the vehicle on the display 21, the control unit 24 draws a vehicle mark or the like on a map based on the vehicle position information detected by the vehicle position detection device 11.
[0015]
The operation panel 12, the voice input unit 13, and the remote control operation unit 14 constitute an input unit of the navigation device. The user gives instructions to the navigation device through these inputs, such as searching for a destination, searching for a route to the destination, and setting a display screen of a display. The operation panel 12 can use, for example, a plurality of operation keys 21 a provided below the display 21. The voice input unit 13 transmits the voice of the user to the input interface 15 via a voice input microphone (not shown), and converts a voice analog signal into a digital signal. The remote control operation unit 14 includes a plurality of input keys, and when the user operates the input keys, the input operation is transmitted to the input interface 15 via wireless. The input interface 15 is connected to the operation panel 12, the voice input unit 13, and the remote control operation unit 14, and transmits input information input by the user to the control unit 24.
[0016]
The storage unit 16 is a recording medium such as a CD, a DVD, or a hard disk, and stores various databases such as map data, addresses, telephones, and facilities required for the navigation device. Preferably, by using a hard disk, large-capacity storage can be realized (for example, 16 GB), and high-speed access and data rewriting can be performed.
[0017]
The audio output unit 17 is connected to the speaker 19 and outputs audio from the speaker 19 under the control of the control unit 24. For example, a voice that prompts attention of a course direction before an intersection is output as information until reaching a destination, or a voice output to a user when a user performs an interactive input to a navigation device. Give instructions. The audio circuit unit 18 is selected by the user when listening to radio or music by the navigation device.
The image output unit 20 is connected to the display 21 and displays a map on the display 21 under the control of the control unit 24, or a vehicle mark indicating the current position of the vehicle on the map, a route to the destination, a distance, a direction, and a vehicle.

The image output unit 20 preferably includes a VRAM such as a FIFO, stores map data read from the storage unit 16 in the VRAM, and combines various data such as vehicle marks on the map data output from the VRAM.
[0019]
As the program memory 22, a ROM or a nonvolatile RAM (for example, a flash memory) can be used. The program memory 22 stores various programs executed by the navigation device, and the control unit 24 performs an operation according to the programs stored in the program memory 22. The program memory 22 of the present invention stores an operation history reproduction program for storing a series of input operations input by the user and reproducing the series of operations in the area 22a. If a RAM is used as the program memory 22, the contents of the program can be modified or upgraded.
[0020]
As the data memory 23, a rewritable nonvolatile RAM such as a flash memory can be preferably used. However, it is possible to use an SRAM or a DRAM other than this, or a flash memory may be used together with the SRAM or the DRAM for backup. When the user inputs predetermined setting items via the operation panel 12, the voice input unit 13, and the remote control operation unit 14, the data memory 23 stores a series of these user input operations in the operation history storage area 23a. .

However, when a hard disk is used for the storage unit 16, the control unit 24 May be directly accessed.
[0021]
The control unit 24 can use, for example, a microprocessor, and controls the entire navigation device by a program in the program memory 22. For example, the vehicle position and orientation are detected based on the output from the vehicle position detecting device 11, a search for a destination, a search for a route thereof, and the like are executed in accordance with an instruction from a user. The required information is notified to the user via 20. Further, as described later, an operation of reproducing a history of a series of input operations input by the user is performed.
[0022]
Next, the operation of reproducing the operation history in the navigation device will be described. FIG. 2 is a flowchart for creating and storing an operation history file required to reproduce a series of input operations input by the user, FIG. 3 is a flowchart for reproducing the input operation, and FIG. 4 is a flowchart for editing the operation history file. It is. Hereinafter, an example in which the user sets “Tokyo Disneyland” as the destination and reproduces it later will be described with reference to the display screen of the display 21 together with a flowchart.
[0023]
(Creating and saving operation history files)
As shown in FIG. 2, when the power of the navigation device is turned on, an operation by the user is started (step S101). At this time, the main screen 51 shown in FIG. The main screen 51 roughly categorizes functions included in the navigation device. In the present embodiment, the main screen 51 displays a menu of “search”, “see”, “remember”, and “change”.
[0024]
At the start of the operation history reproduction program, the control unit 24 sets the hierarchy N = 1 corresponding to the input screen sequentially provided to the user in a hierarchical manner (step S102). For this setting, the data memory 23 or another counter may be used. Next, as shown in FIG. 5, an operation screen or an input screen of layer 1 (N = 1) is displayed on the display 21 (step S103). At the first level, the user inputs an instruction to select “search” from input means such as the operation panel 12 (step S104). The position of the cursor in the figure indicates the position selected by the user. The operation information input by the user is stored in the data memory 23 under the control of the control unit 24 (Step S105). Next, 1 is added to the layer N (step S106), and if the operation by the user does not end, the operations of steps S103 to S106 are repeated.
[0025]
Next, the operation screen of the hierarchy 2 (N = 2) is displayed, and when the user selects “destination”, this input operation is stored in the data memory 23. Thereafter, similarly, “genre” is selected in hierarchy 3, and subsequently, as shown in FIG. 6, “amusement park” is selected in hierarchy 4, “Chiba” is selected in hierarchy 5, and “Tokyo Disneyland” is selected in hierarchy 6 Is selected, and “destination setting” is selected in the last layer 7.
[0026]
When the operation by the user is completed (step S107), the control unit 24 stores a series of input operations of the user from the hierarchy 1 to the hierarchy 7 as an operation history file in the operation history storage area 23a of the data memory 23. At this time, an operation history file is given an operation history name to facilitate identification of the operation history file. In this example, using the names of the layers N = 3, 4, 6, and 7 (“genre”, “amusement park”, “Tokyo Disneyland”, “destination setting”), “genre to amusement park“ Tokyo ” An operation history name or title of "Set Disneyland as a destination" is created.
[0027]
The operation history file is automatically created each time the user sets a predetermined item, and is sequentially stored in the operation history storage area 23a of the data memory 23. In this example, the operation history names are created using the names of the layers N = 3, 4, 6, and 7. However, the operation history names may be created using the names of other layers. Note that the names of the layers indicated by double frames in FIGS. 5 and 6 are used for the operation history names. In addition, in the operation history name, it is desirable to add “” to the proper noun selected by the user. This is to make it easy to see it separately from other parts.
[0028]
(Reproduction and editing of operation history)
Next, an operation for reproducing a user's input operation based on the operation history file stored in the data memory 23 will be described. As shown in FIG. 3, when the navigation device is turned on and the operation by the user is started (step S202), or the user issues an instruction to request the reproduction of the operation history via the operation panel 12 or the remote control operation unit 14. (Step S203), the control unit 24 starts a flow of reproducing the operation history.
[0029]
When the operation history reproduction flow starts, the control unit 24 reads a predetermined number of operation history files from the operation history storage area 23a of the data memory 23 (Step 203). Then, a screen displaying a plurality of operation history names is displayed on the display 21 as shown in FIG. On this screen, operation history names and input buttons 71 and 72 for "edit" and "demo" are displayed in addition to the names. (Step S204). In the example of FIG. 7, in addition to the input operation example described above, operation history names of “set“ Ikspiari ”in Chiba from the address as the destination” and “turn on“ road width display ”on the setting screen” are displayed. Are arranged in chronological order. To display the operation history file stored earlier than this, the screen is scrolled.
[0030]
From the operation history name display screen, the user operates the operation panel 12, the remote control operation unit 14, and the like, and selects “demo” (demonstration) or “edit” of the operation history file to be reproduced (step S205).
[0031]
When the user selects the "demo" input button 72, the control unit 24 reads out the corresponding operation history file stored in the data memory 23, and based on this, executes a series of past input operations performed by the user. It is reproduced (step 206). For example, when the demonstration of “Set amusement park“ Tokyo Disneyland ”as the destination from the genre” is selected, the operation histories of layers 1 to 7 are sequentially reproduced on the display 21. When the input operation by the user is performed by the cursor, the cursor is sequentially moved to the position of the selection item as in the case of FIGS. Is moved to “destination” in the hierarchy 2), and the procedure in which the user has set the destination in the past is reproduced on the display. Further, in addition to the display on the screen, the sound output unit 17 may reproduce the operation procedure by voice. For example, in the reproduction of the hierarchy 3, it is possible to reproduce the sound "Genre selected" in synchronization with the timing when the cursor is moved to "Genre".
[0032]
When the “edit” selection button 71 is selected by the user, the control unit 24 displays an edit screen as shown in FIG. 8 (steps S301 and S302 in FIG. 4). In this example, a case will be described in which “edit” for “set amusement park“ Tokyo Disneyland ”as a destination from genre” is selected. On the editing screen, "ON" and "OFF" selection buttons 81 and 82 for automatic processing are displayed for each layer. When you select the automatic processing "on", the past of the input operation of the hierarchy Ru skipped the input operation of the hierarchy unchanged. On the other hand, when the automatic processing “OFF” is selected, the input operation of the hierarchy can be changed, and a screen waiting for an input from the user is displayed. In other words, the automatic processing “off” has a function of partially changing the contents of the operation history file.
[0033]
For example, if the automatic processing of layers 1, 2, 3, 5, and 7 is set to “ON” and the automatic processing of layers 4 and 6 is set to “OFF” (step S303), the screens of layers 1, 2, and 3 in the reproduction flow Is skipped (step S304), and a genre selection screen of layer 4 as shown in FIG. 9 is displayed (step S305). The user can perform a new input operation different from the past input operation on the genre selection screen, and can specify, for example, “famous place” (step S306). If there is a hierarchy for which the automatic selection has been set to “OFF” (step S307), the operation from step S304 is repeated. Then, a sights selection screen of the hierarchy 6 as shown in FIG. 10 is displayed (step S305). The user selects a desired candidate from a plurality of candidates. If there is no hierarchy of automatic processing “OFF” (step S307), an operation history file with these changes added is newly created and stored. At this time, an operation history name of "set a famous spot" XX castle ruins "as a destination from a genre" is created using the name of the hierarchy. The control unit 24 stores the operation history file in the data memory 23, and executes the setting of the destination according to a series of input operations of the edited user. The user can omit the duplicate input operation only by changing a part of the past input operation. This makes it possible to further improve the operability of the user and provide a comfortable operation.
[0034]
Next, an example in which the operation history reproducing function of the present invention is applied to audio operation of a navigation device will be described. The creation and storage of the operation history files and the operation of reproducing the operation history using these files in the audio operation are the same as those in the navigation operation described above, and are executed according to the flow charts of FIGS.
[0035]
The navigation device includes an audio circuit unit 18 in addition to the navigation function, and the user can enjoy the audio function by using the music media stored in the storage unit 16. FIG. 11 shows an example in which the user sets the screen of the display 21 in the operation of the audio function. As shown in the figure, the user selects “screen effect” in layer 1, selects “power” in layer 2, and selects “fade out” in layer 3. Then, an operation history name “select“ fade out ”by the screen effect” is created using the names of the layers 1 and 3, and this file is stored in the data memory 23. In this example, the operation history name is created using the name of the hierarchy different from that of the navigation operation, but it is possible to appropriately change the hierarchy of the operation history name to be created using the sight of the hierarchy. Can be determined.
[0036]
As described above, the preferred embodiments of the present invention have been described in detail. However, the present invention is not limited to the specific embodiments, and various modifications may be made within the scope of the present invention described in the appended claims. Deformation and modification are possible.
[0037]
For example, in the operation history name display screen shown in FIG. 7, each operation history name is displayed in chronological order. However, the present invention is not limited to this, and operation history files are classified by category (for example, a destination setting category). Or display screen setting category), and the operation history name may be displayed for each category.
[0038]
Further, in the above embodiment, the position of the cursor is moved when a series of input operations by the user is reproduced on the display. However, the reproduction can be displayed using other methods. For example, the selected item can be highlighted in a different color from the other items. Alternatively, a slide screen may be prepared for each layer, and an input operation example may be displayed on the slide screen so that the user can easily understand the input operation.
[0039]
In the above embodiments, the present invention has been described with respect to an in-vehicle navigation device. However, the present invention may be applied to other devices, for example, electronic devices such as an audio device, a personal computer, a home appliance, or a multimedia device combining these devices.
