  However, the conventional technique has a problem that the execution result of a specific task performed in the past cannot be canceled.

  For example, to find a convenience store at a certain time, a convenience store icon is displayed at a convenience store location on the map, and the bank icon is displayed at the bank location this time. Often, the map is filled with a convenience store icon and a bank icon, and the readability is reduced. Therefore, only the execution result of the “display convenience store icon” task may be canceled.

  Since the “display convenience store icon” task and the “display bank icon” task are independent operations and are not hierarchically related, the conventional technology uses the “display convenience store icon” task. The execution result cannot be canceled. In addition, even if some kind of contrivance is used to create a hierarchy between the operations of the “display convenience store icon” task and the “display bank icon” task, in the conventional technology, the execution result of the “display convenience store icon” task When canceling, the execution result of the “display bank icon” task, which is the subsequent task, is also cancelled.

  The present invention has been made to solve the above problems, and provides a navigation device that can easily cancel only the execution result of a specific task without affecting the execution result of another task. For the purpose.

  In order to achieve the above object, a navigation device according to the present invention includes a display device, and provides a presentation unit for presenting guidance information to a driver, and executes a task set by a user. Presenting control means for presenting the guide information changed by the execution result to the presenting means, and when canceling the execution result of the task, a list of the tasks whose current execution result is reflected in the guidance information is displayed on the display device And canceling means for canceling the execution result of the task selected from the listed tasks.

  According to the navigation device of the present invention, the task set by the user is executed by the presentation control means, and the guidance information changed by the task execution result is presented to the presentation means. Also, when canceling the task execution result, the cancel means displays a list of tasks whose current execution result is reflected in the guidance information on the display device, and cancels the task execution result selected from the displayed task. .

  Therefore, a task whose current execution result is reflected in the guidance information is displayed in a list on the display device, and the execution result of the selected task is canceled. Therefore, a specific task is not affected without affecting the execution result of other tasks. Only the execution result of can be canceled easily.

  The navigation device according to the present invention further includes a task history storing task information indicating a task whose current execution result is reflected in the guidance information, and the canceling means cancels the task execution result when canceling the task execution result. Can display a list of tasks indicated by the task information stored in the display device.

  Further, the task history stores task cancellation processing information indicating task cancellation processing for canceling each execution result of the task indicated by the task information together with the task information, and the canceling means stores the task stored in the task history. Based on the information and the task cancellation processing information, the task cancellation processing of the selected task can be executed, and the execution result of the selected task can be canceled. As a result, the task cancellation process of the selected task is executed and the execution result of the task is canceled, so that only the execution result of a specific task can be canceled without affecting the execution results of other tasks.

  As described above, according to the navigation device of the present invention, the task whose current execution result is reflected in the guidance information is displayed in a list on the display device, and the other task is canceled to cancel the execution result of the selected task. It is possible to easily cancel only the execution result of a specific task without affecting the execution result.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the present embodiment, a case where the present invention is applied to a car navigation device will be described.

  As shown in FIG. 1, the car navigation device 10 according to the first embodiment includes an input unit 12 that receives user input regarding the car navigation device 10 and an image that shows guidance information such as map information around the current position. A display 14 to display, a task history database 16 storing a task label as task information added as information indicating a task whose execution result is reflected on the display screen of the display 14, an input unit 12, a display 14, and And a control unit 18 that is connected to the task history database 16 and stores a task control program for controlling various tasks provided in the car navigation apparatus 10.

  The input unit 12 is configured to accept user input using physical buttons and switches, a GUI drawn on a display screen, a voice operation system, or a combination of all or a part thereof.

  The task control program in the control unit 18 includes a task execution module and a task cancellation module. The task execution module is a program for executing a task execution processing routine described later, and sets a set task. The task label indicating the task reflecting the execution result and the cancel subroutine information indicating the task cancel subroutine for canceling the execution result of this task are registered in the task history database 16 in association with each other. . The task cancellation module is a program for executing a task cancellation processing routine to be described later, and cancels the task execution result and deletes a predetermined task label and cancellation subroutine information from the task history database 16. Yes.

  Further, the task control program includes a plurality of task execution processing subroutines for executing each of a plurality of tasks for realizing various functions of the car navigation device 10 (for example, changing the display screen), and each of the plurality of tasks. A plurality of task cancel processing subroutines for canceling execution results are implemented.

  In the task cancellation processing subroutine, it is only necessary to cancel the task execution result (for example, destination setting or icon display), or when it is necessary to change to another state or setting value (for example, map reduction) In the task cancellation processing subroutine involving changes to other states and setting values, the state and setting values after cancellation are determined in advance.

  Further, the task history database 16 includes, for example, a task label of a task which is configured by an HDD and whose execution result is reflected on the display screen of the display 14 and cancel subroutine information indicating the task cancel processing subroutine of this task. And stored. The task label is determined in advance as a task history display label, and the task history database 16 stores, for example, task labels indicating the 10 most recent tasks.

  The car navigation device 10 according to the present embodiment has the configuration and functions of a conventionally known general car navigation device, and the description of the configuration and function of this general car navigation device is omitted.

  Next, the operation of the present embodiment will be described. In the present embodiment, a case will be described in which a task is set and then an execution result of a predetermined task is canceled.

  First, when the input unit 12 is operated by the user, selection and input are repeated hierarchically, and a predetermined task is set, the control unit 18 executes a task registration processing routine shown in FIG.

  First, in step 100, execution of a task execution processing subroutine corresponding to the set task is started. In step 102, the set task is executed by the task execution processing subroutine. The display screen is changed according to the execution result and displayed on the display 14, and the changed map information or the like is presented to the driver.

  In step 104, a task label indicating the set task and cancel subroutine information indicating a task cancel processing subroutine for canceling the execution of this task are additionally registered in the task history database 16, and a task execution processing routine is set. finish.

  Further, when the input unit 12 is operated by the user, for example, when a task cancel button is pressed and a cancel request for a task execution result is input, the control unit 18 executes a task cancel processing routine shown in FIG. The Note that the task cancel button is always displayed on the screen of the display 14 by the GUI.

  First, in step 110, the task label stored in the task history database 16 is displayed as a list of task histories on the display 14. In step 112, the user displays the execution result from the task labels displayed on the display 14. It is determined whether or not the task label of the task to be canceled is selected, and when the user operates the input unit 12 to select the task label, the process proceeds from step 112 to step 114.

  In step 114, the cancel subroutine information corresponding to the task label selected in step 112 is extracted from the task history database 16, and the task cancel processing subroutine indicated by the cancel subroutine information is executed. As a result, when the task execution result is canceled and only the task execution result is canceled, the task execution result is not reflected on the display screen as it is, and the state and setting value after cancellation are not changed. If it is determined in advance, the task execution result is canceled and the display screen is changed to a state after cancellation or to a state set to a predetermined set value.

  In the next step 116, the task label selected in step 112 and the cancel subroutine information corresponding to the task label are deleted from the task history database 16, and the task cancel processing routine is terminated.

  When performing the tasks "Convenience store display", "Destination setting", and "Bank display" after executing the task execution processing routine and task cancellation processing routine described above, the execution result of "Convenience store display" is canceled. Explained as an example.

  When the “convenience store display” task execution processing subroutine is executed, map information is displayed on the display 14 and a convenience store icon is displayed. As shown in FIG. 4, the “convenience store display” task cancellation processing subroutine is displayed. And the task label “Convenience Store Display” are additionally registered in the task history database 16.

  When the “execution of destination” task execution processing subroutine is executed, the map information and the convenience store icon indicating the location of the convenience store are displayed on the display 14, and the guidance information to the set destination is also displayed. Further, as shown in FIG. 5, cancellation subroutine information indicating a task cancellation processing subroutine of “Destination setting” and a task label of “Destination setting” are additionally registered in the task history database 16.

  When the “bank display” task execution processing subroutine is executed, the bank icon indicating the bank position is also displayed while the map information, the convenience store icon, and the guidance information to the destination are displayed on the display 14. Further, as shown in FIG. 6, cancellation subroutine information indicating a “bank display” task cancellation processing subroutine and a task label of “bank display” are additionally registered in the task history database 16.

  Next, when the task cancel button is pressed to cancel the execution result of the “convenience store display”, a list of task labels is read from the task history database 16, and the execution result is displayed on the display screen as shown in FIG. A task label list is displayed on the display 14 as a task history indicating a task in which is reflected. When "Convenience store display" is selected from the task label list displayed on the display 14, the task cancellation processing subroutine corresponding to "Convenience store display" is called and the task cancellation processing subroutine corresponding to "Convenience store display" is executed. Then, the execution result of the task “Convenience Store Display” is canceled, and, as shown in FIG. 8, the task label and “Cancellation Subroutine Information” of the “Convenience Store Display” are deleted from the task history database 16, and the task label list on the display 14 is displayed. The display of is terminated. The display 14 displays only map information, guidance information to the destination, and bank icons.

  As described above, according to the car navigation device of the embodiment of the present invention, the task label of the task whose current execution result is reflected on the display screen is displayed in a list on the display, and the selected task label is displayed. Since the task cancellation processing subroutine of the task shown is executed to cancel the task execution result, only the execution result of a specific task can be canceled easily without affecting the execution results of other tasks.

  In addition, in order to retain the task label and cancellation subroutine information of the task in which the execution result is reflected in a unit independent from each other in the task history, without affecting the execution result of the task before and after the corresponding task, Only the execution result of the corresponding task can be canceled.

  Conventionally, in order to cancel the execution results of tasks such as “Destination setting” and “Convenience store display” that have been performed in the past, it is necessary to perform operations according to each task. In this embodiment, the task label of the task whose execution result is reflected is displayed based on the task history database regardless of the type of task. By implementing a unified operation method of selecting a task for which a result is to be canceled, cancellation can be easily performed.

  In the above embodiment, the case where the guidance information changed according to the task execution result is displayed on the display screen of the display has been described as an example. However, the present invention is not limited to this. The changed guidance information may be presented to the driver.
