Next, another specific example of the operation of the information device 1 will be described with reference to FIG.
Hereinafter, a case where the function extraction unit 33 extracts a plurality of functions for generating a shortcut in the state of FIG. 5 will be described.

Based on the device information or history information, the function extraction unit 33 extracts a function “change to a detour route” and a function “change to a toll road priority route” as a function for generating a shortcut (step ST1). . Here, the extraction of the function “change to a detour route” is based on the traffic information included in the device information, and the reason for extracting the function is, for example, that an accident occurred 2 km ahead in the current guidance route . Also, the extraction of the function “change to a toll road priority route” is based on history information, and the reason for extracting the function is, for example, that there is a history of changes in the past at the current position.
Next, the shortcut generation unit 34 generates a shortcut for a function “change to a detour route” and a function “change to a toll road priority route” (step ST2).
Next, the determination unit 35 determines that it is necessary to execute the function of each shortcut (step ST3; YES), and the execution unit 36 performs a route search function “change to a detour route” and “toll road” The route search function of “change to the preferred route” is executed (step ST4).
Next, the auxiliary information generation unit 37 generates tenth auxiliary information and third auxiliary information (step ST5).
The auxiliary information generation unit 37 generates tenth auxiliary information using the execution result of the function acquired from the execution unit 36 (step ST22). Further, the auxiliary information generating unit 37 generates the reason why the function extracting unit 33 has extracted the function “change to a detour route” as tenth auxiliary information (step ST24). The auxiliary information generation unit 37 generates, as tenth auxiliary information, information on a route that detours to reach the destination and information that an accident has occurred 2 km away. A duplicate description of the generation of the third auxiliary information is omitted.
Next, in step ST6, the shortcut presentation control unit 38 determines which shortcut information is to be presented based on the importance determined in advance for the function of the shortcut. Here, it is assumed that the importance of the function “change to a detour route” is higher than the importance of the function “change to a toll road priority route”. In this case, the shortcut presentation control unit 38 displays the shortcut “change to a detour route” and the shortcut “change to a toll road priority route” on the shortcut display unit 39 and displays the tenth auxiliary information as a shortcut. Displayed on the unit 39 and the display unit 8.
FIG. 15 is a diagram illustrating an example of a display of a shortcut “change to a detour route”, a shortcut “change to a toll road priority route”, and tenth auxiliary information. As described above, the shortcut presentation control unit 38 is configured to determine the auxiliary information to be presented based on the degree of importance predetermined for the function of the shortcut, so that the user can display the auxiliary information. It can be recognized that the shortcut is higher in importance.

Next, another specific example of the operation of the information device 1 will be described.

Hereinafter, the vehicle information and the vehicle periphery information included in the information device 1 are referred to as vehicle status information.

The device information acquisition unit 31 acquires vehicle status information as device information.
The shortcut presentation control unit 38 controls the presentation of auxiliary information based on the vehicle status information included in the device information acquired from the device information acquisition unit 31.
For example, when the vehicle status information indicating that the vehicle is traveling is acquired, the shortcut presentation control unit 38 does not present auxiliary information and acquires the vehicle status information indicating that the vehicle is stopped. If so, provide auxiliary information.
The shortcut presentation control unit 38 does not present auxiliary information when the vehicle status information indicating that the vehicle is traveling in the intersection is acquired, for example, and the vehicle is not traveling in the intersection. If vehicle status information indicating this is acquired, auxiliary information is presented.
By comprising in this way, it can prevent that the increase in the amount of information accompanying presentation of auxiliary information obstructs driving of a vehicle.

Thus, by presenting information that assists selection of a shortcut together with a shortcut, an information device that can prevent an increase in the number of operations can be obtained.

In addition, after the user selects a shortcut and executes the function of the shortcut, for example, when the function is unsuitable, the user performs an operation to cancel the function. The canceling operation is, for example, an operation of pressing a button labeled “return”. According to the information device 1 according to the first embodiment, the information for assisting selection of the shortcut is presented together with the shortcut, so that the chance of performing the cancel operation can be reduced. The shortcut is a function that can be executed by a single operation that can only be executed by a plurality of operations, and may require a plurality of operations to be canceled. According to the information device 1, the opportunity to perform such multiple operations can be reduced. Further, by reducing the chance of performing the cancel operation, the chance of hindering another operation such as driving can be reduced, and safety can be improved.

Also, the auxiliary information generation unit 37 according to the information device 1 of Embodiment 1 generates information indicating an execution result when the shortcut is selected as the auxiliary information and the function of the shortcut is executed. Thus, the user can grasp the execution result of the shortcut function before selecting the shortcut. Since the user can select a shortcut in which a desired execution result is suggested, it is possible to reduce the opportunity for a cancel operation.

In addition, for example, when only the shortcut “change to detour route” is displayed, it is impossible to know which way to go, so the user who selects the shortcut and executes the function of the shortcut “I didn't change it if I knew it would be this route,” sometimes complained. On the other hand, according to the information device 1 according to the first embodiment, it is possible to reduce the chance that the user is dissatisfied with the execution result of the shortcut function.

In addition, according to the first embodiment, the information device 1 includes a device information acquisition unit 31 that acquires device information including information on available functions, and a history that acquires history information including information on used functions. An information acquisition unit 32, the function extraction unit 33 extracts a function based on the device information or the history information, and the auxiliary information generation unit 37 extracts a function based on the function extraction reason in the function extraction unit 33. The reason is generated as auxiliary information. For this reason, before selecting a shortcut, the user can grasp the reason why the shortcut is generated and determine whether or not the shortcut needs to be selected. Thereby, after selecting the shortcut and executing the function of the shortcut, it is possible to reduce the chance of performing the cancel operation.
