In the example shown in FIG. 4, the display on the display screen of the display 20 includes a menu button 24, a prompt display 26, and a voice recognition result display 28.

The prompting display 26 may include a question or question related to the current surroundings of the vehicle (hereinafter, represented by "question"). In the example shown in FIG. 4, it is assumed that the vehicle has entered a traffic jam section as the current peripheral situation of the vehicle. In this case, the prompting display 26 comprises a question such as "How is the traffic jam now?". This is different from the output that prompts the user to create a tweet in a completely undirected manner, such as "Please tweet something from now on", but the output that asks the user to answer the information used to create the tweet. Is. As a result, the user can tweet as if answering a question, which makes it easier for users who are not accustomed to Twitter. However, it may be an output (output that gives direction to the user) that prompts the creation of a tweet related to the surrounding conditions of the vehicle, such as "Please tweet something about this traffic jam from now on".

In the example shown in FIG. 4, the user answers "I can't see the beginning" in response to the question "How about the traffic jam now?". In this case, as shown in FIG. 4, the voice recognition result "I can't see the beginning" is output as the voice recognition result display 28. Based on the response from this user, the processing device 10 creates a tweet that can be finally posted. The creation of this tweet may be executed, for example, by the user selecting an automatic creation button (not shown) prepared on the display screen of the display 20 after outputting the voice recognition result display 28.

FIG. 5 is a diagram showing an example of a tweet created by the processing device 10 based on the response from the user shown in FIG.

In the example shown in FIG. 5, the answer from the user "I can't see the beginning" is used for the part "I can't see the beginning". That is, the answer from the user "I can't see the beginning" is used in a manner of filling in the part in parentheses of "feeling that the beginning cannot be seen". In this way, it is possible to efficiently create a tweet in a manner in which only the word part that fills in the blank is spoken. In the example shown in FIG. 5, "R40" is a user name.

In the example shown in FIG. 5, the processing device 10 edits the response from the user to create a tweet, but even if the response from the user is used as it is for the word part to fill in the blank, the tweet is created. Good.

FIG. 6 is a flowchart showing an example of the main processing executed by the processing apparatus 10 of this embodiment.

In step 600, the current location name (address, etc.) is acquired from the navigation device 40. The current location name may be derived based on the map data of the navigation device 40 and the vehicle position information.

In step 602, congestion information is acquired from the navigation device 40. The congestion information may be, for example, level 1 (character information) from VICS (registered trademark).

In step 604, it is determined whether or not the distance of the traffic jam exceeds a preset threshold value based on the traffic jam information acquired in step 602. The threshold value may be a fixed value or a variable value (for example, a variable value according to the road type). Further, the threshold value may be arbitrarily set by the user. If the traffic jam distance exceeds the threshold value, the process proceeds to step 606, and if the traffic jam distance does not exceed the threshold value, the process proceeds to step 608. If the distance of the traffic jam does not exceed the threshold value, the process may return to step 600.

In step 606, a question prompting the creation of a tweet regarding the traffic jam is output (see sign 26 in FIG. 4).

In step 608, the current time is acquired from the navigation device 40.

In step 610, the destination arrival time is acquired from the navigation device 40.

In step 612, a candidate sentence (see FIG. 3B) representing the current situation is created based on the information acquired in steps 608 and 610. As shown in FIG. 3B, the created candidate sentence may be output on the display screen of the display 20 in the form of a button.

In step 614, it is determined whether or not the button of each candidate sentence output on the display screen of the display 20 is selected. If the predetermined time has elapsed without the button being selected, the process may return to step 600. If the button is selected, the process proceeds to step 616. A plurality of buttons may be selected (that is, a plurality of candidate sentences may be selected).

In step 616, the candidate sentence selected in step 616 is pasted to generate a tweet, which is presented to the user (see FIG. 5). At this time, the tweet before posting may be modified according to the input from the user via the input device 30. Further, the final posting of the tweet may be executed by the user selecting a posting button (not shown) provided on the display screen of the display 20.

In the process shown in FIG. 6, after outputting a question prompting the creation of a tweet regarding the traffic jam in step 606, a candidate sentence regarding the current surrounding environment (traffic jam) is created based on the information from the navigation device 40, and the user Present to. As a result, the user can receive assistance in creating a tweet by selecting a candidate sentence (by answering a question). Also in the process shown in FIG. 6, after outputting a question prompting the creation of a tweet regarding the traffic jam in step 606, the voice recognition device is turned on to form a state in which a response is received by an utterance from the user. May be good. In this case, when a response is received from the user's utterance, a tweet based on the response from the user may be created in the above-described manner with reference to FIGS. 4 and 5.

Further, in the process shown in FIG. 6, in this case, after outputting a question prompting the creation of a tweet regarding the traffic jam in step 606, a candidate sentence is created and displayed as a button, but in step 606, regarding the traffic jam. Before outputting the question prompting the creation of the tweet, the candidate sentence may be created, and in step 606, the question prompting the creation of the tweet regarding the traffic jam may be output, and at the same time, the candidate sentence may be displayed as a button. Alternatively, as described above in FIGS. 2 and 3, the candidate sentence may not be displayed until the button 24b (see FIG. 2) for displaying the candidate sentence regarding the current situation is selected by the user.

The process shown in FIG. 6 outputs a question prompting the creation of a tweet at the start point of the traffic jam (at the time when the traffic jam occurs), but outputs a question prompting the creation of a tweet at the intermediate point or the end point of the traffic jam. You may. Further, for example, in the case of an accident congestion, considering that the accident situation is of concern to the driver of the following vehicle, a question prompting the creation of a tweet may be output when passing near the accident site. ..

FIG. 7 is a flowchart showing another example of the main processing that may be executed by the processing apparatus 10 of this embodiment.

In step 700, it is determined whether or not the predetermined tourist object is within the field of view of the user (typically, the driver) based on the information from the navigation device 40. Predetermined tourism objects may include natural objects such as famous mountains, rivers and lakes, and famous man-made objects (towers, archaeological sites, etc.). When the predetermined tourist object is within the user's field of view, the process proceeds to step 702.

In step 702, a question prompting the creation of a tweet regarding the tourist object detected in step 700 is output. For example, when the tourist object is Mt. Fuji, a question such as "How is Mt. Fuji today?" Is output.

In step 704, a candidate sentence regarding the tourist object detected in step 700 is created. The created candidate sentence may be displayed in the form of a button as a candidate sentence indicating the current situation (see FIG. 3B). The candidate sentence for the tourist object is arbitrary and may be a fixed candidate sentence or a variable candidate sentence. For example, when the tourist object is Mt. Fuji, one or more fixed candidate sentences such as "Mt. Fuji that cannot be seen well today" and "Mt. Fuji, a superb view!" May be prepared.

Steps 706 and 708 may be similar to steps 614 and 618 of the process shown in FIG.

In the process shown in FIG. 7, after outputting a question prompting the creation of a tweet about the tourist object in step 702, a candidate sentence regarding the tourist object is created and presented to the user. As a result, the user can answer the question and receive assistance in creating a tweet by selecting a candidate sentence. Also in the process shown in FIG. 7, after outputting a question prompting the creation of a tweet about the tourist object in step 702, the voice recognition device is turned on to form a state in which a response is received by an utterance from the user. You may. In this case, when a response is received from the user's utterance, a tweet based on the response from the user may be created in the above-described manner with reference to FIGS. 4 and 5.

Further, also in the process shown in FIG. 7, the processes of steps 608 and 610 shown in FIG. 6 are executed, and candidate sentences including these information are separately created, or these information are used as candidate sentences related to tourism objects. It may be incorporated and presented to the user.

According to the tweet creation assisting device 1 of the present embodiment described above, the following excellent effects are particularly exhibited.

As described above, since a question prompting the user to create a tweet about the surrounding environment of the vehicle is output based on the information from the navigation device 40, it is possible to appropriately trigger the information transmission in advance of the user's desire to tweet. it can. In particular, when there is a change in the surrounding environment of the vehicle (for example, in the above example, when a traffic jam is encountered or a tourist object comes into view), a question is asked to encourage the creation of tweets related to the change. By outputting, this effect becomes remarkable.

In addition, since a tweet is created by creating a candidate sentence about the surrounding environment of the vehicle and letting the user select it, the user can complete the tweet to be posted with a simple operation, which improves convenience. To do.
