[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a dialogue control device according to an embodiment of the present invention.
In FIG. 1, a dialogue device 1 is a dialogue processing unit that controls the content of a dialogue with a vehicle user 3 who inputs voice via a voice input unit 2. On the other hand, the storage unit 4 stores the contents of the dialogue between the dialogue device 1 and the user 3 from the position information of the vehicle and the time information detection unit 6 obtained from the position information detection unit 5 using GPS (Global Positioning System) or the like. Time information obtained from the vehicle, the surrounding information of the own vehicle obtained from the own vehicle surrounding information detecting unit 7 using an infrared sensor, a camera, and the like, and the driving information obtained from the driving information detecting unit 8 such as a sensor provided in a steering or a brake. Further, it is a storage unit for storing as a history of conversation contents together with driver information such as the expression of the user 3 (driver) and heart rate obtained from the driver information detection unit 9 such as a camera or a biological sensor.
[0009]
In addition, the similar situation determination device 10 determines a similar conversation situation from the stored conversation history based on the current vehicle position information, time information, own vehicle surrounding information, driving information, and driver information. This is a processing unit. Note that the dialog device 1 presents to the user 3 dialog contents corresponding to the dialog status determined to be similar by the similar status determination device 10.
[0010]
FIG. 2 is a diagram illustrating an example of information stored in the storage unit 4. The dialog content between the interactive device 1 and the user 3 is a history of the dialog content. Geographical position information, date information, number of people information, etc., and vehicle position information, time information obtained from GPS or the like at that time, information on the surroundings of the vehicle using infrared sensors, cameras, etc. , Driving information captured by sensors such as steering and brakes, and driver information such as facial expressions and heart rate captured by cameras and biological sensors.
[0011]
Next, the operation of the dialog control device according to the present embodiment will be described with reference to the drawings. FIG. 3 is a flowchart showing the operation of the dialog control device according to the present embodiment. It is assumed that the storage unit 4 stores the history of the contents of the dialog in various situations.
In FIG. 3, first, when a voice is input via the voice input unit 2 (step S1), the dialog control device determines whether or not the same dialog content has been used in the past in the dialog device 1 based on the status number of the dialog. A determination is made (step S2).
If the same conversation content has been used in the past in step S2 (YES in step S2), the similar situation determination device 10 determines the position information of the vehicle by the position information detecting unit 5, the time information by the time information detecting unit 6, The vehicle surrounding information detection unit 7 acquires the vehicle surrounding information, the driving information detection unit 8 driving information, and the driver information detection unit 9 driver information (step S3).
[0012]
Then, the current dialogue state is compared with the history of the dialogue contents stored in the storage unit 4 to determine whether or not the similarity is large (step S4).
Here, the similarity determination is performed by selecting information used for the determination from the vehicle position information, time information, own vehicle surrounding information, driving information, and driver information in accordance with the attribute of the input dialogue content. The priority of time and the matching determination range are changed. As a result, when some pieces of information match, it is determined that they are similar. For example, when the input dialogue content relates to a place name, the similarity of the position information is determined as the highest priority item.
In this case, the match determination range may be slightly enlarged in order not to narrow down candidates to be presented to the user 3 more than necessary. Further, in this case, since items such as vehicle information are considered to have low relevance, they are not used for similarity determination.
[0013]
If, in step S4, the current dialogue state has a higher similarity than the history of the dialogue content stored in the storage unit 4 (YES in step S4), the user 3 is notified of the dialogue content having the higher similarity. The content is presented (step S5), and the user is asked to input whether to set automatically (step S6).
If the user 3 desires automatic setting in step S6 (YES in step S6), the interactive device 1 executes a process according to the content of the interaction with the user 3 (step S7), and the operation of the interactive control device. To end.
[0014]
On the other hand, if the same conversation content has not been used in the past in step S2 (NO in step S2), or in step S4, the current conversation content is compared with the history of the conversation content stored in the storage unit 4. If the degree of similarity is low (NO in step S4), or if the user 3 does not desire automatic setting in step S6 (NO in step S6), the interactive device 1 Is input (step S8).
[0015]
The storage unit 4 stores the position information of the vehicle by the position information detecting unit 5, the time information by the time information detecting unit 6, the own vehicle surrounding information by the own vehicle surrounding information detecting unit 7, the driving information by the driving information detecting unit 8, the driver The driver information is acquired by the information detecting unit 9 (step S9) and stored together with the state number indicating the content of the dialog (step S10).
Further, the interactive device 1 executes a process according to the content of the interaction with the user 3 (step S7), and ends the operation of the interactive control device.
[0016]
In addition, by providing the interactive device 1, the storage unit 4, and the similar situation determination device 10 described in the above-described embodiment on the information center side connected to the vehicle by wireless communication, the load on the device on the vehicle side is reduced. May be reduced.
[0017]
As described above, when a voice is input from the voice input unit 2, the dialog control device of the present embodiment determines whether or not the same dialog content has been used in the past in the dialog device 1 based on the status number of the dialog. judge. If the same conversation content has been used in the past, the similar situation determination device 10 determines the position information of the vehicle by the position information detecting unit 5, the time information by the time information detecting unit 6, and the surroundings of the own vehicle by the own vehicle surrounding information detecting unit 7. The information, the driving information by the driving information detecting unit 8, and the driver information by the driver information detecting unit 9 are acquired. Then, it is determined whether or not the similarity of the dialogue stored in the storage unit 4 is greater than the degree of similarity by comparing the current dialogue state with the history of the dialogue contents stored in the storage unit 4. If the similarity is higher than the history, the dialogue content having the higher similarity is presented to the user 3 to urge the user 3 to perform automatic setting.
[0018]
Therefore, when the same content is repeatedly input by the user 3, the dialog control device determines the input content in advance and presents it to the user 3, and the user 3 confirms the presented content. The input can be performed only by the user, and the effect of reducing the burden on the user 3 in the input can be obtained.
[0019]
【The invention's effect】
As described above, according to the dialogue control apparatus of the first aspect, the similar situation determination unit determines that the current vehicle traveling state is a dialogue state similar to the history of the dialogue content stored in the dialogue history storage unit. If it is determined that there is, the dialog content presenting means presents to the user the dialog content according to the dialog situation determined to be similar, so that the user only has to confirm the presented content and execute the input. Will be able to
Therefore, when the user repeatedly inputs the same content, the user can perform the input only by confirming the presented content, thereby reducing the burden on the user in the input. Is obtained.
