The answer information is associated with the memory of the questions received from the driver.

The external information acquisition unit 3 acquires the question target output from the meaning understanding unit 21, performs an inquiry related to the question target, and acquires the answer information of the question target. The external information acquisition unit 3 outputs the acquired response information of the question target to the response message generation unit 22 of the question response unit 2. Further, the external information acquisition unit 3 may obtain the response information from, for example, a local network, or may obtain general information about the route or the object as the answer information by the Internet or the like.

Further, when receiving the inquiry of the necessary information for the output text generated by the information generation control unit 5, the external information acquisition unit 3 acquires the information corresponding to the inquiry and outputs the information corresponding to the inquiry to the provided information generation control unit 5. .

The information generation control unit 5 performs information control processing, and the reference history storage unit 25 estimates the driver's guidance route by using the modality of the question raised by the driver's guidance route guided by the vehicle guidance device 600 or the like. The degree of certainty, and the degree of confidence as the driver's understanding of the guiding path, etc., and based on the degree of understanding, determine the detail of the output text and the timing of the output that should be provided on the guiding path, generating the guidance data generating unit 63 control information.

Further, the output control unit 4 outputs the output text information outputted by the output text generating unit 52 as control information to the guidance material generating unit 63.

Here, as shown in FIG. 2, the question response unit 2 includes the question analysis knowledge storage unit 23, the response text template 24, and the history storage unit 25. However, the problem analysis knowledge storage unit 23 is not limited thereto. The response template 24 and the history storage unit 25 can be stored in, for example, a server external to the information providing control device 100, and the meaning understanding unit 21 accesses the server via the network or the like to refer to the question analysis knowledge storage unit 23 and the response text. The template 24 or the history memory unit 25.

That is, the information providing control device 100 has the processing circuit 301 for controlling the generation of the guidance material by the guidance material generating portion 63 based on the accepted voice input content.

The processing circuit 301 may be a dedicated hardware as shown in FIG. 3A, or may be a CPU (Central Processing Unit) 306 that executes a program stored in the memory 305 as shown in FIG. 3B.

When the processing circuit 301 is a dedicated hardware, the processing circuit 301 is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmable processor, an ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or a combination of the above.

When the processing circuit 301 is the CPU 306, each of the input accepting unit 1, the meaning comprehensing unit 21, the response text generating unit 22, the external information acquiring unit 3, the output control unit 4, the detail determining unit 51, and the output text generating unit 52 The function is achieved by a combination of software, firmware, or a combination of software and firmware.

It is realized by a processing circuit such as a CPU 306 or a system LSI (Large-Scale Integration) of a program such as a disk drive 302 or a memory 305. Further, the program stored in the HDD 302, the memory 305, or the like may be such that the computer executes the input accepting unit 1, the meaning understanding unit 21, the response text generating unit 22, the external information acquiring unit 3, the output control unit 4, and the detail determining unit 51. And a program or method of the output text generating unit 52. Here, the memory 305 is a nonvolatile such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), or an EEPROM (Electrically Erasable Programmable Read-Only Memory). Or non-volatile semiconductor memory, or a magnetic disk, a flexible disk, a magnetic disk, a CD (compact disk), a minidisc, a DVD (Digital Versatile Disc), and the like.

Further, the functions of the input accepting unit 1, the meaning comprehensing unit 21, the response text generating unit 22, the external information acquiring unit 3, the output control unit 4, the detail determining unit 51, and the output text generating unit 52 may be partially dedicated.

In addition, this is only an example, and the question analysis knowledge storage unit 23, the response text template 24, the history storage unit 25, and the output timing table 53 may be configured by a DVD, a memory 305, or the like.

Further, the information providing control device 100 includes an input interface device 303 and an output interface device 304 that communicate with external devices such as the input device 700 and the vehicle guidance device 600.

Explain the action.

In general, the information providing control device 100 according to the first embodiment of the present invention executes a process described later: a question response process that accepts a question from the driver and generates a response message to the question; the information providing process is based on the driver's request The degree of comprehension judged by the question arises to generate control information for controlling the vehicle guidance device 600 to generate the guidance material.

First, the action of the question response processing is explained, which accepts a question from the driver and generates a response to the question.

Fig. 4 is a flow chart for explaining the operation of the question response processing in the information providing control device 100 according to the first embodiment of the present invention.

Further, the premise of the question response processing explained in FIG. 4 is that the vehicle guidance device 600 is in a state of providing guidance information to the driver, for example. Specifically, for example, the driver uses the input device 700 to perform a route search instruction, and the vehicle guidance device 600 generates guidance data based on the obtained search result (its This guide data is converted into sound material as a guide path information for guiding a route to the destination, and can be output to the state of the output device 800.

The input accepting unit 1 stands by until the question of the route proposed by the driver is received from the input device 700 (the case of [NO] in step ST401). In a state where the vehicle guiding device 600 starts the route guidance, the driver can freely ask questions about the path being guided, for example, to the input device 700, "turn right here ( right )", "Go straight here ( Straight forward )" and other sounds. The input accepting unit 1 determines whether the driver has raised a question regarding the route as described above.

When receiving the question from the driver (in the case of [YES] in step ST401), the input accepting unit 1 converts the accepted voice data into a text and outputs it to the meaning understanding unit 21. For example, here, when the driver asks a question about "Want to turn right here" for the route, the input accepting unit 1 converts the sound data of "turn right here" to "turn right here." The text is output to the meaning understanding section 21.

The meaning comprehension unit 21 refers to the meaning analysis table 231 of the question analysis knowledge storage unit 23, and determines whether or not the character string of the speech mode matches the character string represented by the text acquired from the input accepting unit 1 (step ST402).

In step ST402, if there is no speech mode in which the character string matches (NO in step ST402), the processing is terminated.

When there is a speech mode in which the character string matches in the step ST402 (in the case of [YES] in step ST402), the meaning understanding unit 21 acquires the question symbol corresponding to the speech mode in which the character string matches (step ST403). The meaning understanding unit 21 outputs the acquired question symbol to the response message generation unit 22.

Here, FIG. 5 is a view for explaining an example of information stored in the meaning analysis table 231 in the first embodiment.

As shown in Fig. 5, in the meaning analysis table 231, the utterance mode and the question symbol are stored correspondingly.

The question symbol is determined in advance, and in the first embodiment, it is expressed as "YES_NO{next_cross=RIGHT}" shown in Fig. 5, for example.

The first half of the question symbol indicates the type of question, and the second half of the question symbol indicates the details of the question. For example, "YES_NO" when the question symbol is "YES_NO{next_cross=RIGHT}", and "YES_NO" indicates a question type that can be answered with a negative expression such as "Yes" or a negative expression such as "No". In addition, "{next_cross=RIGHT}" indicates that the details of the question content are, asking that the next intersection is a right turn.

Regarding the type of question, such as "YES_NO", the type of question that can be answered with a positive expression such as "Yes" or a negative expression such as "No" is generally called a non-question sentence. Here, the question of the form of the non-interrogative sentence is referred to as the YES_NO type, and other things, such as "Would you like to turn right in front of a few meters?" and "Where to turn next?" The type of question that is answered "or not" is called an open question.

Further, the content of the question symbol is described as an example in the fifth diagram, and the expression of the question symbol is not limited thereto.

In step ST401, the meaning understanding unit 21 acquires a text such as "Where to turn right here", and if the content of the fifth figure is stored in the meaning analysis table 231, the meaning analysis table 231 has and "here is The character string of the "right turn" is consistent with the speech mode, so the meaning understanding unit 21 obtains from the meaning analysis table. The question symbol "YES_NO{next_cross=RIGHT" corresponding to "Please turn right here" (step ST402, 403).

The meaning comprehension unit 21 compares the question symbol acquired in step ST403 with the object table 232 of the question analysis knowledge storage unit 23, and acquires a question object corresponding to the question symbol from the object table 232 (step ST404). The meaning understanding unit 21 outputs the acquired question object to the external information acquisition unit 3.

Here, Fig. 6 is a view showing an example of information stored in the object table 232 in the first embodiment.

As shown in Fig. 6, in the object table 232, the question symbol is stored in association with the question object. The question symbol is the same as the question symbol stored in the meaning analysis table 231.

In the first embodiment, the object to be questioned is information which the external information acquisition unit 3 asks. The question object is preset for each question symbol and stored in the object table 232 corresponding to the question symbol.

For example, if the content of the object table 232 is as shown in FIG. 6, the meaning comprehension unit 21 acquires the question object "the advancing direction of the next intersection" corresponding to the question symbol "YES_NO{next_cross=RIGHT}" acquired in step ST403. "." Then, the meaning comprehension unit 21 outputs the question object "the advancing direction of the next intersection" to the external information acquisition unit 3.

The external information acquisition unit 3 acquires the question target output from the meaning understanding unit 21, and makes an inquiry about the question target, and acquires the answer information of the question target (step ST405). Specifically, for example, when the question object obtained from the meaning comprehension unit 21 is "the advancing direction of the next intersection", the external information acquisition unit 3 inquires and acquires the guidance route information and the vehicle position information, and acquires the distance. The direction of the intersection of the nearest intersection to the location of the vehicle is the answer information of the question. The external information acquisition unit 3 can acquire the guidance route information from, for example, the guidance data generation unit 63, and can acquire the vehicle position information from the position detection unit 62. In addition, as an example, the external information acquisition unit 3 inquires various information in the vehicle guidance device 600 and obtains the response information, but is not limited thereto. For example, the response information can be obtained from the regional network. General information about the path or object can be obtained from the Internet or the like as an answer message.

In addition, in the first embodiment, the forward direction is expressed by RIGHT, STRAIGHT, LEFT, etc., and in step ST405, the external information acquisition unit 3 acquires "STRAIGHT" indicating that the direction of the next intersection is straight. As an answer to the information.

The external information acquisition unit 3 outputs the acquired response information to the response message generation unit 22.

Further, in the first embodiment, the information providing control device 100 is installed in the vehicle guidance device 600. Therefore, as described above, the external information acquisition unit 3 acquires guidance route information for guiding the driver, for example, the advancing direction of the intersection. As the answer information, this is only an example, and the external information acquisition unit 3 acquires the response information corresponding to the question target. For example, when the information providing control device 100 is installed in the work device that performs the maintenance check operation and acquires the next check point item as the target of the question, the external information obtaining unit 3 acquires the information of the place or position to be next detected as the answer information.

The response message generation unit 22 generates a response message based on the question symbol output by the meaning understanding unit 21 in step ST403 and the response information outputted by the external information acquisition unit 3 in step ST405 (step ST406). Specifically, examples For example, the question mark outputted by the meaning understanding unit 21 in step ST403 and the answer information outputted by the external information acquisition unit 3 in step ST405 are obtained, and the response message is determined by referring to the response template 24, thereby generating a response message.

The response message generation unit 22 outputs the acquired response message to the output control unit 4.

Here, Fig. 7 is a view for explaining an example of the response template 24 in the first embodiment, and Fig. 7A is an example of the response template 24 in the case where the question symbol is "YES_NO{next_cross=RIGHT}", 7B. The figure shows an example of the response text template 24 in the case where the question symbol is "WHICH{obj=next_cross}".

As shown in FIGS. 7A and 7B, in the response text template 24, a response message corresponding to the inquiry result information is defined for each question symbol. Further, the inquiry result information sets the answer information that is assumed to be obtained from the external information acquisition unit 3.

Here, in step ST403, the question symbol "YES_NO{next_cross=RIGHT}" is output, and in step ST405, it is assumed that the response information "STRAIGHT" is output. Therefore, the response text generating unit 22 refers to the response text template 24 shown in Fig. 7A. , get the response text "No. Go straight."

Further, in the first embodiment, the response text template 24 is defined in advance, and the response text generating unit 22 uses the response text obtained from the response text template 24 as the response text outputted to the output control unit 4, but is not limited thereto. The response text generating unit 22 can also generate a response text by other methods.

The response text generating unit 22 stores the response text acquired in step ST406 in the history storage unit 25 (step ST407). At this time, the response text generating unit 22, the response text and the time information, and the text acquired by the meaning understanding unit 21 from the input accepting unit 1 in step ST401 (that is, the question posed by the driver), step ST403 The question symbol obtained by the medium meaning comprehension unit 21 is stored in the history storage unit 25 in association with the answer information output from the external information acquisition unit 3 in step ST405 (see FIG. 8).

Here, the time referred to here is, for example, the mechanical current time in the clock (not shown) in the information providing control device 100. This is only an example. For example, the time may be the time at which the input accepting unit 1 receives the text of the question from the input device 700, or may be the time at which the position detecting unit 62 detects and responds to the timing at which the text generating unit 22 obtains the response message. At the time, it is sufficient to set the timing of which timing to be used as the reference for the time stored in the history storage unit 25, and the time information based on the reference may be used.

By the operation of the step ST407, the response text to the question raised by the driver is associated with the question raised by the driver, the answer information obtained by inquiring the question, and the like, and is accumulated and stored in the history storage unit 25. In other words, the history memory unit 25 accumulates the history of the questions raised by the driver accepted by the input accepting unit 1.

The response message generation unit 22 outputs the response message acquired in step ST406 to the output control unit 4, and the output control unit 4 generates sound data from the response message by voice synthesis processing, and outputs the sound from the output device 800 (step ST408). The sound synthesizing process performed by the output control unit 4 may be performed using a known technique in the same manner as the voice recognition process performed by the input accepting unit 1.

Thereby, the sound of "No. To go straight." is outputted from the output device 800, and the driver receives a response to the question "Please turn right here."

In addition, as an example of the above description, the driver's question is "Please turn right here", and the question mark obtained for the question. The type of question is YES_NO. However, the same type of action is used when the question type of the question symbol is an open question.

For example, suppose the driver asks a question about "Where to turn next." In this case, the meaning understanding unit 21 acquires the question symbol of "WHICH{obj=next_cross}", and acquires the "direction of the next intersection" as the question object corresponding to the question symbol (steps ST403, 404).

Then, the external information acquisition unit 3 outputs the response information of "STRAIGHT" to the "direction of the next intersection" (step ST405), and the response message generation unit 22 refers to the response template 24 as shown in FIG. 7B. A response message "After going straight." is obtained (step ST406). Then, the response text generating unit 22, when outputting the response message "to be straight ahead" to the output control unit 4, memorizes the response text in association with the time, the question asked by the driver, the question symbol, and the answer information. The history storage unit 25 (refer to Fig. 8 in step ST407).

The output control unit 4 generates a sound material "to go straight ahead", and causes the output device 800 to output it (step ST408).

As such, the question response function can be implemented in the information providing control device 100, and the driver can obtain a response corresponding to the question to the path.

Next, the action of the information providing process is explained, which is based on the degree of understanding judged by the driver's question, and generates control information for controlling the generation of the guidance data in the vehicle guidance device 600.

Further, as described above, the degree of understanding is a degree to which the driver understands the guidance route and the like.

In addition, the question response processing and the information providing processing illustrated in FIG. 4 In the execution of the information providing process, the question response processing described in FIG. 4 is executed in advance, and the history of the question raised by the driver is memorized in the history storage unit 25.

Further, at the time of execution of the information providing process, the information providing control device 100 transmits a guidance material generation control start instruction to the guidance material generating portion 63 of the vehicle guidance device 600, which is used to indicate that it is to be based on the information providing control device later. Guide information is generated by the control information transmitted from 100. The guidance data generating unit 63 generates the guidance data based on the control information transmitted from the information providing control device 100 when receiving the guidance material generation control start instruction until the guidance data generation control end instruction is received from the information provision control device 100. .

FIG. 9 is a flow chart for explaining the operation of the information providing process in the information providing control device 100 according to the first embodiment of the present invention.

The question determination unit 511 of the detail level determination unit 51 executes the degree of understanding determination process and determines the degree of understanding of the driver (step ST901). Specifically, the question determining unit 511 determines the degree of understanding indicating how much the driver has an understanding of the guidance route or the like. Further, in the first embodiment, the degree of understanding is "high" or "low".

The question determining unit 511 outputs the determined degree of understanding of the driver to the detail level determining unit 512 of the detail level determining unit 51.

Fig. 10 is a flowchart for explaining the operation of the degree of understanding determination processing performed by the question determining unit 511 in the first embodiment.

The understanding degree determination processing of step ST901 of Fig. 9 will be described in detail with reference to Fig. 10.

First, the question determining unit 511 refers to the history storage unit 25 to determine whether it is The question response processing is executed while traveling on the current route (step ST1001). In addition, when traveling on the current route, the vehicle itself travels on the path that the vehicle guide 600 is now guiding.

For example, the question response processing is executed as to whether or not the vehicle is traveling on the current route, and the flag can be appropriately used. Specifically, when the vehicle guidance device 600 receives the route search instruction, the guidance flag stored in the vehicle guidance device 600 that the information providing control device 100 can refer to is set to 1, and in the question response process, the response message is When the history of the question is stored in the history storage unit 25 (step ST407 in FIG. 4), the generation unit 22 also adds and memorizes the information of the guidance flag (the illustration of the guidance flag is omitted in FIG. 8). Then, in this step ST1001, the question determining unit 511 can perform the question response processing when it is determined whether or not the vehicle is traveling on the current route, depending on whether or not the question of the in-progress flag 1 is added. Further, in this case, if the driver guides the current route (for example, inputs a guidance end instruction from the input device 700, or changes the destination or the like), the accepting unit 61 accepts the guidance end instruction and stores the internal storage. The guidance flag is initialized (=0), and information indicating that the guidance of the guidance end or the change of the destination or the like is received is output to the response message generation unit 22, and the response message generation unit 22 displays the guidance flag in the history storage unit 25. All updated to 0.

In addition, this is only an example. For example, the time at which the route search instruction issued by the driver is received is previously stored in the vehicle guidance device 600, and the question determination unit 511 can receive the time stored in the history storage unit 25. The question history after the time of the route search instruction is determined as the question response executed when traveling on the current route. In this way, the question determining unit 511 only needs It is possible to judge whether or not the question response processing is executed while driving on the current path, and any method can be used.

In step ST1001, when the question determining unit 511 determines that the question response processing is not performed at all when traveling on the current route (that is, the question history stored when the history memory unit 25 is not traveling on the current route) (in the case of [NO] in step ST1001), the question determining unit 511 sets the degree of understanding to "high" (step ST1004), and outputs the information of the degree of understanding "high" to the detail level determining unit 512, and ends. deal with.

In step ST1001, when the question determining unit 511 determines that the question response processing is executed when traveling on the current route (that is, when the history storage unit 25 has the question history stored when traveling on the current route) (in the case of [YES] in step ST1001), the question determining unit 511 estimates the driver for the latest history among the question history stored in the history memory unit 25 when it is traveling on the current route. For the degree of certainty of the guidance path, it is judged whether the degree of confidence is high or low (step ST1002). In this step ST1102, the question determining unit 511 estimates the degree of confidence by using the tone in which the driver makes a question (for example, the degree of confidence in the route is high or the degree of suspicion of the route is high).

Specifically, for example, the question judging unit 511 obtains the content of the question in the latest history among the question histories that are stored in the history memory unit 25 when the user is traveling on the current route, as shown in FIG. The confidence estimation table set in advance using the tone of the question is used to estimate the degree of certainty. In addition, the degree of certainty estimation table shown in FIG. 11 is an example, and the degree of certainty estimation table may be set in advance in accordance with the degree of certainty.

For example, the question is "The next step is xx. ×× When the form is equal, the degree of confidence in the route is high, and the driver's confidence can be determined to be high.

On the other hand, for example, the question is "Will it be xx next time? ×× In the form of "), etc., the degree of suspicion is high, so it can be assumed that the driver's confidence is low.

In other words, the question determining unit 511 estimates the degree of certainty that the driver has confidence in the guidance route by using the tone determined by the question form.

In addition, this is an example, and the question determining unit 511 may estimate the degree of certainty by using a method other than the tone. For example, the question determining unit 511 uses the tone information at the end of the sentence to generate a confidence estimation table by using a high degree of doubt when the tone of the ending is raised. The so-called ending tone information is, for example, a text of "?" in order to indicate that the ending is raised. For example, when the input accepting unit 1 receives a question from the driver and converts the voice data into a text (refer to step ST401 in FIG. 4), when the voice data that is raised at the end of the conversion is added, the text of "?" is added and then output to The meaning understanding unit 21 stores the text to which the "?" is attached as the content of the question in the history storage unit 25. When the question determination unit 511 refers to the confidence estimation table, it is also necessary to check whether the tone information at the end of the sentence includes "?" "."

When the question determining unit 511 determines that the degree of certainty is low (in the case of [YES] in step ST1002), the question determining unit 511 sets the degree of understanding to "low" (step ST1003), and the degree of understanding is "low". The information is output to the detail level determining unit 512, and the processing ends. In the first embodiment, the question determining unit 511 determines the degree of understanding using the degree of certainty. When the degree of certainty is low, the degree of understanding is set to "low", and when the degree of certainty is high, the degree of understanding is set to "high". . In other words, the question determining unit 511 uses the degree of confidence in the tone estimation as the degree of understanding. To judge the degree of understanding.

For example, if the question is in the form of "Will it be xx?", it can be presumed that the driver has doubts about the route he is guided, and the degree of certainty is low. Therefore, the question determining unit 511 sets the degree of understanding to "low" based on the estimation result that the driver's confidence level is low.

When the question determining unit 511 determines that the degree of certainty is high (in the case of [NO] in step ST1002), the question determining unit 511 sets the degree of understanding to "high" (step ST1004), and the degree of understanding is "high". The information is output to the detail level determining unit 512, and the processing ends. For example, if the question is in the form of "Next xx is right", it can be presumed that the driver is convinced that the path his vehicle is traveling is correct with respect to the route it is guided (ie, is being guided) On the path of the route), it is likely to be confirmed only for the sake of caution. Therefore, the question determining unit 511 sets the degree of understanding to "high" based on the estimation result that the driver's confidence level is estimated to be high.

As described above, the question determining unit 511 estimates whether or not the driver is convinced of the degree of confidence in the route based on whether or not the driver has received a question of the driver's question about the route when traveling on the current route. Degree, and judge the degree of understanding based on the degree of certainty.

In addition, in step ST1002, the question determination unit 511 estimates the degree of certainty using the latest history among the question history stored in the history memory unit 25 when it is traveling on the current route, but Without being limited thereto, the question determining unit 511 may estimate the degree of confidence using the previous history stored in the history storage unit 25. Further, the question determining unit 511 may not use the history that has passed a certain time.

Go back to the flowchart in Figure 9.

The detail determination unit 512 acquires the information of the degree of understanding outputted by the question determination unit 511 in step ST901, and determines the detail level of the output text output by the output device 800 in the vehicle guidance device 600 (step ST902). Here, for example, the detail level determining unit 512 determines that the detail level is "low" if the degree of understanding is "high", and determines that the detail level is "high" if the degree of understanding is "low". Further, the output text output by the vehicle guidance device 600 to the output device 800 is here the content of the guidance material for route guidance.

The output text generation unit 52 refers to the output timing table 53, and acquires an output text template corresponding to the detail level outputted by the detail degree determining unit 512 in step ST902, and an output timing based on the output text of the output text template (step ST903).

Here, Fig. 12 is a view for explaining an example of the output timing table 53 in the first embodiment. Fig. 12A shows an output timing table 53 in the case where the detail is "high", and Fig. 12B shows an output timing table 53 in the case where the detail is "low".

In the output timing table 53, the output text template and the timing of outputting the output based on the output text template are defined in association with each other. In the first embodiment, as shown in FIG. 12A and FIG. 12B, an output timing table 53 corresponding to the case where the detail degrees "high" and "low" are respectively prepared is prepared in advance.

The output text generation unit 52 outputs the information of the output timing table 53 obtained in step ST903 (specifically, the output text template and the information on the output timing of the output text) to the external information acquisition unit 3.

The external information acquisition unit 3 determines whether or not the output of the output text has been reached based on the guidance route information, the vehicle position information, and the map data based on the timing at which the output text is output from the output text generation unit 52 in step ST903. Step ST904). The external information acquisition unit 3 can obtain the guidance route information from the guidance data generation unit 63, and the position detection unit 62 acquires the vehicle position information, and the data storage unit 65 acquires the map data.

When it is determined in step ST904 that the timing at which the output text is output has not been reached (in the case of [NO] in step ST904), the processing in step ST904 is repeatedly executed.

When it is determined in step ST904 that the timing of outputting the output text has been reached (in the case of [YES] in step ST904), the external information acquisition unit 3 is based on the output text template corresponding to the timing at which the output text is output. The information necessary for generating the output text is obtained, and is output to the output text generating unit 52 together with the information of the output timing (step ST905).

Specifically, for example, the detail level determining unit 512 determines that the detail level is "high", and the external information obtaining unit 3 acquires the information shown in FIG. 12A from the output text generating unit 52. Then, the external information acquisition unit 3 determines, from the guidance route information, the vehicle position information, and the map data, that the vehicle position is 1 km (km) from the intersection at which the forward direction is to be changed. At this time, the external information acquisition unit 3 determines that the output of the output text has been reached (YES in step ST904), and obtains an output text template corresponding to an output timing of 1 km from the intersection at which the distance is to be changed. The information necessary for outputting the text is generated about 1 km ahead of the direction of the ○, that is, the direction information for changing the forward direction is obtained, and is output to the output text generating unit 52 together with the information of the output timing.

In the output text template of the output timing table 53 shown in FIG. 12A and FIG. 12B, for example, "○" which is "about 1 km ahead and advances in the direction of ○" is filled with, for example, "right". The text or text column of the direction. external The information acquisition unit 3 acquires information in the specific direction from the guidance route information or the like, and outputs the information to the output text generation unit 52.

In addition, in the output text template, for example, "$locale $" in the "crossroads where the previous $ landmarks are located" can be filled with a character or a character string indicating a specific landmark such as "A supermarket".

In this way, the output text generation unit 52 inquires of the external information acquisition unit 3 about the information necessary for generating the output text, and the external information acquisition unit 3 acquires the information corresponding to the inquiry and outputs it to the output text generation unit 52.

In addition, when the detail level is "low", as shown in Fig. 12B, "there is 1km from the intersection where the direction of the direction is to be changed" is not defined as the timing of the output of the output text, so the external information is obtained. The portion 3 does not determine that it is the timing to output the output text even if it is determined that there is a place of 1 km from the intersection at which the forward direction is to be changed.

The output text generating unit 52 generates an output message based on the information indicating the output timing output from the external information acquiring unit 3 and the information necessary for generating the output text, and outputs the output text to the output control unit 4 (step ST906). Specifically, for example, the output text generating unit 52 generates information indicating an output text of "about 1 km ahead and advancing to the right", and outputs the information to the output control unit 4.

The output control unit 4 transmits the information indicating the output text outputted by the output text generating unit 52 to the guidance material generating unit 63 of the vehicle guidance device 600 as control information.

The guidance data generating unit 63 uses the information indicating the output of the control information obtained from the output control unit 4 as the guidance material, and outputs the guidance data to the guidance control unit 64. For example, the guidance control unit 64 causes the output device 800 The obtained guidance data is output as sound data. The guidance control unit 64 may convert the guidance material into sound data by a well-known sound synthesis process as described above. In addition, here, the guidance control unit 64 converts the guidance data into a sound and outputs it, but it is not limited thereto, and may be converted into an image output.

Then, the process returns to step ST904, and the subsequent process is repeated. When the external information acquisition unit 3 determines that the output timing corresponding to the detail level has been reached, the output message generation unit 52 generates information indicating the output of the output template. The output control unit 4 outputs the generated information indicating the output text to the vehicle guidance device 600, and uses the output text as the guidance material, converts it into a sound, and outputs the output device 800.

Here, after step ST906, the process returns to step ST904. However, the process proceeds to step ST901, and the degree of understanding is re-determined based on the latest question response history.

For example, when the driver inputs the guidance end instruction or the like by the input device 700 to end the current route guidance, the receiving unit 61 of the vehicle guidance device 600 accepts the guidance end instruction and provides the received guidance end instruction to the information providing control. The device 100 outputs, and the information providing control device 100 ends the information providing process. At this time, the information providing control device 100 outputs a guidance material generation control end instruction to the guidance data generation unit 63 of the vehicle guidance device 600.

Further, in the first embodiment, the output text generating unit 52 generates an output message based on the information indicating the output timing output from the external information acquiring unit 3 and the information necessary for generating the output text, and transmits the output text to the output control unit 4 via the output control unit 4. The information indicating the generated output text is output as the control information to the guidance data generating unit 63, but is not limited thereto. For example, the output text generating unit 52 may be transparent. The output control unit 4 outputs the information indicating the output timing outputted by the external information acquisition unit 3 and the information necessary for generating the output text as control information to the guidance data generation unit 63, and the guidance data generation unit 63 generates the information based on the control information. Output text (ie, guidance material).

As described above, according to the first embodiment, a question raised by the driver of the user of the vehicle guiding device 600 regarding the information that the vehicle guiding device 600 can provide (for example, a question regarding the guiding route) is accepted, by using the question. The tone of the presumption of the degree of confidence to determine the user's understanding, and based on the degree of understanding, the output of the output after the details of the output and the timing of the output, therefore, without the user's question, can be understood by the user The guidance content of the degree, the frequency suitable for the user's understanding frequency, and the provision of information such as route guidance. In this way, for example, unnecessary information is not provided to users with high understanding, and detailed information can be provided to users with low understanding, and information that is easy for the user to understand can be provided.

In addition, in judging the degree of comprehension of the user, in the method of outputting a question to the user and obtaining the user's answer to the question, there is a problem as follows: a large number of users must be prepared in advance. Various questions. On the other hand, in the first embodiment of the present invention, the degree of comprehension of the user is determined based on the question posed by the user. Thereby, not only the trouble of the user is reduced, but also various questions asked to the user are not prepared in advance.

Further, the degree of certainty is estimated by the tone estimated by the user's question in the form of a question, and the degree of understanding is judged by the degree of certainty. Therefore, the degree of understanding can be judged by a relatively simple method.

In addition, using the tone of the question to estimate the degree of certainty, therefore, based on the test The control of information is provided in consideration of the degree of understanding of the user's subjective feelings.

Further, in the first embodiment, the driver is asked to input a question for the route by using the voice. However, the driver is not limited thereto, and the driver can input the text by using an input device such as a keyboard, thereby inputting the pair. Path to the question.

Further, in the first embodiment, the guidance material and the response to the question are outputted by the output device 800 in the form of sound data. However, the output device 800 may be a display screen or the like, and the guidance material may be The response text is also displayed on the output device 800.

In the first embodiment, the meaning understanding unit 21 refers to the meaning analysis table 231 to obtain the question symbol in step ST403 of FIG. 4, but the present invention is not limited thereto. For example, the meaning comprehension unit 21 can also describe the speech mode using a regular expression. Further, the meaning understanding unit 21 can also learn the question symbol with respect to the text in advance using the method of mechanical learning, and determine the question symbol based on which question symbol is classified as the accepted text.

Further, in the fourth embodiment, the degree of certainty, the degree of understanding, and the detail are described as two values of "high" and "low", but the present invention is not limited thereto. For example, more detailed confidence, comprehension, or detail can be defined, using its corresponding output timing table 53 to control the output text in more detail.

Further, in the first embodiment, the information providing control device 100 is installed in the vehicle guidance device 600, and the information providing control device 100 controls the information providing function, specifically, on the guided route. The function of path guidance on the way, but is not limited to this.

For example, the information providing control device 100 is a device that controls the information providing function in the device checkpointing support device installed in the facility, and receives the user as a user. The equipment checkpoint operator, etc., asked about the equipment maintenance of the equipment checkpoint operation support device and the work information in the equipment checkpoint (for example, what the equipment checkpoint operator should check next), and should answer the question and memorize the question. In response to the history, based on the memorized resume, the device checkpoint operator determines the degree of understanding of the job in the equipment checkpoint, and changes the detail of the output job information according to the degree of understanding.

Fig. 13 is a view showing the configuration of a device checkpointing support device 900 to which the information providing control device 100 of the first embodiment is mounted.

As shown in FIG. 13, the equipment checkpoint operation support device 900 receives, from the input device 700, a route search instruction, for example, to a device checkpoint position, which is input to the input device 700 by a device checkpoint worker or the like, and is provided in the information providing control device 100. Under control, the related information of the path to the next device checkpoint corresponding to the path search indication that has been accepted to the device checkpoint position is output from the output device 800.

Further, the device checkpoint operation support device 900 is preset to, for example, a server provided in the device checkpoint office.

The equipment checkpoint operation support device 900 includes an accepting unit 71, a position detecting unit 72, a checkpoint data generating unit 73, a guidance control unit 74, and a data storage unit 75.

The accepting unit 71 receives, from the input device 700, a route search instruction or the like that is input to the input device 700, for example, to the device checkpoint position, such as a device checkpoint worker.

The position detecting unit 72 is configured by, for example, a speedometer, a gyroscope, a GPS (Global Positioning System) receiver, or the like, and detects the current position, speed, azimuth, current time, and the like of the equipment checkpoint operator. In addition, the position detecting unit 72 It is also possible to combine two or more of these sensors and receivers.

The position detecting unit 72 outputs information such as the current position, speed, azimuth, and current time of the equipment inspection worker or the like detected by the position detecting unit 72 to the inspection point data generating unit 73.

For example, the checkpoint data generating unit 73 is based on the route search instruction that has been received by the receiving unit 71 to the device checkpoint position, the information stored in the data storage unit 75, the current position and speed of the device checkpoint operator that has been output by the position detecting unit 72, and the speed. Information such as orientation, current time, etc., explores the path to the next device checkpoint location, and generates checkpoint data to indicate the explored path or checkpoint content. The inspection point data generating unit 73 outputs the generated guidance data to the guidance control unit 74. Further, when the information providing control device 100 outputs the control information, the checkpoint data generating unit 73 generates the checkpoint data based on the control information. In addition, here, the control information includes an output text or information indicating an output timing.

For example, the guidance control unit 74 converts the checkpoint data generated by the checkpoint data generating unit 73 into sound data, and outputs the output data to the output device 800. In addition, here, the guidance control unit 74 converts the inspection data into sound data and outputs it, but the limitation is not limited thereto. For example, the guidance control unit 74 converts the guidance data into image data and outputs the same. can.

The data storage unit 75 stores map data, various materials for route search, and the like. The data storage unit 75 is composed of, for example, an HDD (Hard Disk Drive), a DVD (Digital Versatile Disc), a memory, or the like.

Here, as shown in Fig. 13, the equipment checkpoint operation support device 900, the input device 700, and the output device 800 are independent devices. In addition, the input device 700 is a sound input device preset to a microphone or the like, and the output device 800 is a sound output device such as a speaker or a display device such as a display screen. These can also be integrated with portable terminals such as smart phones or head-mounted displays.

Here, FIG. 15 is a view for explaining an example of a cooking program searched by the program material generating unit 83 of the conversational robot controller 1000.

For example, as shown in Fig. 15, in the case of cooking the same food, the cooking program searched by the program data generating unit 83 differs depending on whether it is for a novice or a veteran. Alternatively, the cooking program that the program data generating unit 83 should select may also be different for people who have time and who want to cook quickly.

The program data generating unit 83 generates program data for indicating the most appropriate cooking program in response to the state or knowledge of the cook. Further, the program data generating unit 83 stores in advance the mode of the cooking program to be searched, for example, an instruction to search for the cooking program based on which mode is received from the cook or the like, and then the cooking program search and program data based on the accepted instruction. It can be produced.

The device 800 is integrated into a portable terminal such as a smart phone.

The configuration and operation of the information providing control device 100 are the same as those of the information providing control device 100 installed in the vehicle guiding device 600 described above.

Further, in the above description, the information providing control device 100 is installed in the vehicle guidance device 600, and performs a process of receiving a question from the driver and generating a question response process for the response to the question; based on the driver's request. The degree of understanding judged by the question is generated by the information providing process for controlling the generation of the guidance material in the vehicle guidance device 600. On the other hand, as shown in FIG. 14 , when the conversation robot control device 1000 is installed, the information providing control device 100 executes a process to be described later: a question response process, and receives a question about a cooking program, such as a cooking program, and generates a question. The response message for the question; and the information providing process generate control information for controlling the generation of the program data in the conversation robot control device 1000 based on the degree of understanding determined based on the question raised by the cook or the like.

Then, the program material generating unit 83 of the conversation robot control device 1000, based on the control information provided by the information providing control device 100, for example, searches for a program for completing the target food, and generates a program for indicating the searched, or a seasoning focus. The program data is output to the guidance control unit 84. The guidance control unit 84 outputs the program data from the output device 800. In other words, according to the control of the conversational robot controller 1000, information related to the cooking program such as the program for completing the target cooking or the seasoning focus is supplied from the output device 800 to the cook or the like.

Alternatively, for example, the information providing control device 100 is a device that controls an information providing function in the work support device that describes the method of using the device, and accepts a question about which action to be performed by the user by, for example, pressing a certain button. At the same time as the question should be answered, the question response history is memorized, and based on the memorized history, the user's understanding of the use of the machine is determined, and the details of the information to be output are changed due to the degree of understanding. .

Embodiment 2

In the first embodiment, the detail level determining unit 51 estimates the degree of confidence of the user using the tone of the question raised by the user, determines the degree of understanding from the degree of certainty, and determines the detail level of the output text based on the degree of understanding.

However, sometimes the degree of certainty estimated by the use of the user's questioning tone cannot be properly judged.

For example, in the first embodiment, the driver's question "the next step is to turn right", the detail level determining unit 51 expresses a high degree of confirmation because of the question form. In tone, the confidence level is "high" and the level of detail provided later is set to low. As a result, the detailedity of the path guidance information outputted later is low, and the frequency of the output path guidance information is lowered.

However, in fact, because it is a crossroad that should be turned left, the driver who asked the question "Next turn right" is to think of the left turn in the guide path as a right turn, and is convinced. In this case, it is better to provide more detailed information to the driver so that the driver can master the correct guiding path.

Therefore, in the embodiment described in the second embodiment, the information included in the question and the information included in the answer information of the question object are compared with each other, and the degree of the agreement is considered to determine the user's Comprehension.

The configuration of the information providing control device 100 according to the second embodiment of the present invention is the same as the configuration described with reference to the second embodiment in the first embodiment, and thus the overlapping description will be omitted.

In addition, the hardware configuration of the information providing control device 100 is also the same as that described in the third embodiment and the third embodiment in the first embodiment. A slightly repeated explanation.

Hereinafter, in the second embodiment, as in the first embodiment, the information providing control device 100 is attached to the vehicle guidance device 600 (see FIG. 1), and in the vehicle guidance device 600, information is provided. The control executed by the control device 100 provides guidance route information and the like to a driver or the like as a user.

The action is explained.

In the same manner as the first embodiment, the information providing control device 100 according to the second embodiment of the present invention performs the processing described later: the question response processing, which accepts a question from the driver and generates a response message to the question; The control information for controlling the generation of the guidance material of the vehicle guidance device 600 is generated based on the degree of understanding judged based on the question posed by the driver.

The specific operation of the question response processing by the information providing control device 100 according to the second embodiment of the present invention is the same as the operation described with reference to FIG. 4 in the first embodiment, and thus the overlapping description will be omitted.

The information providing control device 100 according to the second embodiment of the present invention differs from the information providing control device 100 according to the first embodiment in the first embodiment in the first embodiment in the step ST901 of the ninth embodiment described in the tenth embodiment. Since the contents of the operation of the degree of judgment processing are described in detail, only the operation different from the first embodiment will be described in detail, and the other operations similar to those of the information providing control device 100 according to the first embodiment will be omitted.

Fig. 16 is a flow chart for explaining the operation of the degree of understanding determination process performed by the question determining unit 511 in the second embodiment.

The question determining unit 511 determines whether or not it is driving on the current route. The question response processing is performed (step ST1301). The specific operation is the same as that of step ST1001 in Fig. 10, and therefore the overlapping description will be omitted.

In step ST1301, when the question determining unit 511 determines that the question response processing is not performed at all when traveling on the current route (that is, the question history stored when the history memory unit 25 is not traveling on the current route) (in the case of [NO] in step ST1301), the question determining unit 511 sets the degree of understanding to "high" (step ST1306), and outputs the information of the degree of understanding "high" to the detail level determining unit 512, and ends. deal with.

In step ST1301, when the current route is traveling, there is a question about the route that is received by the receiving driver, and there is a response to the question (that is, there is a present in the history memory unit 25). In the case of the question history of the memory when the route is traveling (in the case of [YES] in step ST1301), the question determining unit 511 writes a question that is memorized when it is stored on the current route in the history memory unit 25. The latest history in the history is judged whether or not the question form is questionable (step ST1302). The specific operation is the same as that of step ST1002 in Fig. 10, and therefore the overlapping description will be omitted.

When the question determining unit 511 determines that the degree of certainty is high (in the case of [NO] in step ST1302), the question determining unit 511 calculates the question answer matching degree W (step ST1303).

Here, FIG. 17 is a flowchart for explaining an operation of the question determining unit 511 to calculate the question answer matching degree W in the second embodiment.

The operation of step ST1303 will be described in detail using Fig. 17 .

First, the question judging unit 511 updates the latest history of the question history stored in the current history on the current path stored in the history storage unit 25. The information of the question and the information of the answer information are obtained (step ST1401). In other words, the question determining unit 511 acquires the content of the question from the driver that has been stored in the history storage unit 25 and the answer information for the question obtained by the external information obtaining unit 3.

For example, the question determining unit 511 estimates the direction included in the question based on the content of the question acquired in step ST1401 (step ST1402). Here, the question determining unit 511 determines whether the word of the designated route included in the question is a word such as "right" or "left" indicating the direction, and if it is a word indicating the direction, the direction is estimated to be included in the question. The direction. For example, when the content of the question is "When you want to turn right here", since the word "right" is included, the question determining unit 511 estimates that the result obtained by the direction included in the question is "RIGHT".

In addition, the result obtained by the question determining unit 511 in estimating the direction included in the question is indicated by "RIGHT", "LEFT", "NONE", etc., but it is not limited thereto, and it may be expressed in any manner. As long as it is a way of understanding the result of the estimation direction.

The question determining unit 511 estimates the direction included in the answer information acquired in step ST1401 (step ST1403). Specifically, the question determining unit 511 determines whether or not the word related to the direction is included in the answer information, and if there is an inclusion, the direction is used as the direction included in the answer information. Here, the answer information of the question object is answered by "RIGHT", "LEFT", etc., and when the "RIGHT", "LEFT", etc. are included, the question determining unit 511 uses the "RIGHT" and "LEFT". Wait for the direction included in the answer message.

Further, for example, in the second embodiment, "HOW_DISTANCE{obj=next_turn, next_cross=RIGHT}" is acquired, As a question mark for the question "Want to turn right in the first few meters", the question object is a structure including "the next intersection direction" and "the distance to the next intersection". In addition, the answer information such as "RIGHT" and "100m" is obtained.

The question determining unit 511 compares the direction included in the question estimated in step ST1402 with the direction included in the answer information estimated in step ST1403, and calculates the question answer matching degree W (step ST1404).

Specifically, the question determining unit 511 converts the direction estimated in steps ST1402 and ST1403 into angle information, and calculates the question answer matching degree W.

For example, the question determining unit 511 converts the estimated direction into angle information in the following manner: right: RIGHT=0 degrees; left: LEFT=180 degrees; front: STRAIGHT, FORWARD=90 degrees; rear: BACKWARD=270 degrees .

Then, the question determining unit 511 calculates the question answer matching degree W based on the following formula.

W=|100-|X-Y|/180×100|

X: the angle of the transition from the direction included in the question

Y: the angle of the direction conversion from the inquiry result

Here, the unit of the question answer matching degree W is %.

Here, for example, the question determining unit 511 estimates in step ST1402 that the direction included in the question is "RIGHT", and in step ST1303, it is estimated that the direction included in the answer information is "RIGHT", and the question determining unit 511 The question answer matching degree W=100% was calculated from the following formula.

W=|100-|0-0|/180×100|

In addition, for example, the question determining unit 511 estimates in step ST1402 that the direction included in the question is "RIGHT", and in step ST1403, it is estimated that the direction included in the answer information is "LEFT", and the question determining unit 511 calculates the question answer. Consistency W = 0%.

In addition, for example, the question determining unit 511 estimates in step ST1402 that the direction included in the question is "STRAIGHT", and in step ST1403, it is estimated that the direction included in the answer information is "RIGHT", and the question determining unit 511 calculates the question answer. Consistency W = 50%.

In addition, for example, if the question answer matching degree W cannot be calculated because the direction included in the question cannot be estimated, the question determining unit 511 determines the question answer matching degree W=0%.

As described above, the question determining unit 511 calculates the question answer matching degree W from the direction included in the question and the direction included in the answer information by the driver.

In addition, in step ST1302 and step ST1303, the question determining unit 511 determines the degree of understanding using the latest history among the question histories stored in the history memory unit 25 when traveling on the current route, or The question answer matching degree W is calculated, but the question determining unit 511 may determine the degree of understanding using the previous history stored in the history storage unit 25 or calculate the question answer matching degree W. Further, the question determining unit 511 may not use the history that has passed a certain time.

Go back to the flowchart of Figure 16.

When the question answer matching degree W is calculated in step ST1303, the question determining unit 511 determines whether or not the question answer matching degree W is equal to or lower than the first threshold Th1, that is, whether or not W≦Th1 is established (step ST1304). Here, for example, it is assumed to be set to the first threshold Th1=50%. This is only an example, and the first threshold Th1 can be appropriately set as appropriate.

In the case of W ≦ Th1 (that is, when W is 50% or less) (in the case of [YES] in step ST1304), the question determining unit 511 sets the degree of understanding to "low" (step ST1305). The information of the degree of understanding "low" is output to the detail level determining unit 512, and the processing ends.

As described above, for example, in the case where the driver is convinced and asks a question such as "the next right turn right" before the intersection that should turn left, it is based on the use of the user. The degree of certainty that is presumed by the tone of the question cannot properly judge the degree of understanding.

Therefore, in the second embodiment, when it is estimated that the driver has a high degree of confidence in the route (in the case of [NO] in step ST1302), if the question answer matching degree W is less than the first threshold Th1, the degree of understanding is " Low, whereby the guidance route information can be more appropriately provided in response to the actual situation of the driver.

In the case where W ≦ Th1 is not established (that is, when W is greater than 50%) (in the case of [NO] in step ST1304), the question determining unit 511 sets the degree of understanding to "high" (step ST1306). The information of the degree of understanding "high" is output to the detail level determining unit 512, and the processing ends.

On the other hand, in step ST1302, the question determining unit 511 determines that the degree of certainty is low (in the case of [YES] in step ST1302), and the question determining unit 511 sets the degree of understanding to "low" (step ST1305), and will understand Degree of "low" The information is output to the detail level determining unit 512, and the processing ends.

When the driver's confidence is low, it can be thought that the driver is asking the question because he wants more detailed information to make him convinced of the guiding route, so it is better to provide more detailed information to the driver.

Therefore, in the case where the question determining unit 511 determines that the degree of certainty is low, the question determining unit 511 sets the degree of understanding to "low" regardless of the question answer matching degree W. Thereby, when the detail level determination unit 512 determines the detail level of the output text, the apparatus can output an output text having a higher detail level to make the driver confident. In other words, it is possible to prevent an output sentence having a low level of detail from being output because it is judged that the degree of understanding is "high". As a result, the guidance route information can be more appropriately provided in response to the actual situation of the driver.

As described above, the question determining unit 511 considers the direction included in the question and the answer information of the question object acquired by the external information obtaining unit 3 in consideration of the degree of certainty estimated by the questioning mood in the understanding degree determining process. The extent to which the directions are included is the same to determine the user's understanding.

Here, FIG. 18 is a view showing an example of the relationship between the degree of understanding, the question answer matching degree W, and the degree of certainty in the degree of understanding determined by the question determining unit 511 in the second embodiment.

In addition, in one of the examples shown in Fig. 18, the question answering degree of agreement W and the degree of certainty are both binarized. In the second embodiment, the question determining unit 511 determines the degree of understanding by asking the question answering degree W and the degree of confidence (AND condition).

The detail level determining unit 512 determines the detail level based on the degree of understanding obtained by the question determining unit 511, and changes the information provided to the driver.

Here, the question determining unit 511 sets the degree of understanding to two values of "low" and "high", and the question determining unit 511 divides the degree of understanding into two stages. However, this is only an example. For example, the question determining unit 511 considers The degree of understanding is further subdivided (for example, into three stages, etc.) to the extent that the direction included in the question raised by the driver and the direction included in the answer information of the question object obtained by the external information acquisition unit 3 match.

For example, when W≦Th1 is not satisfied in the step ST1304 (in the case of [NO] in step ST1304), it is determined whether or not Th1<W<Th2 is established using the second threshold Th2. If yes, the question determining unit 511 will understand. The degree is set to "medium" (refer to step ST1601 of Fig. 19, step ST1602).

Then, the detail level determining unit 512 determines the degree of detail in accordance with the degree of understanding distinguished by the question determining unit 511. At this time, the output timing table 53 is defined in advance based on the detail level determined by the detail level determining unit 512.

In addition, in the case of the second embodiment, the question determining unit 511 uses the direction (that is, the information of the orientation) when calculating the question answer matching degree W, but is not limited thereto. For example, the question answer matching degree W may be calculated based on the distance of a three-dimensional geographic coordinate such as a landmark. For example, the question answer matching degree W can be calculated based on the name of the building.

For example, the history memory unit 25 remembers that the question content is "turning at the restaurant A side", the question symbol is "HOW_DISTANCE{obj=next_turn, landmark=restaurant A}", and the answer information is "{landmark=restaurant B}" .

In this case, the question determining unit 511 calculates the question answer matching degree W based on the geographic coordinates of the landmark information landmark. For example, suppose the geographic coordinates of landmark A are H1=(X1, Y1, Z1), and the geographic coordinates of landmark B are H2=(X2, Y2, Z2), the question determining unit 511 calculates the Euclidean distance between H1 and H2, and if it is below a certain threshold, the question answer matching degree W is calculated to be 100%, otherwise the question answer matching degree W is calculated to be 0%.

Further, regarding the geographic coordinates of the landmark A and the landmark B, for example, the question determining unit 511 may inquire the external information acquiring unit 3 or acquire it through the external information acquiring unit 3.

Further, for example, the question determining unit 511 can calculate the question answer matching degree W based on the name of the building. Specifically, for example, the question determining unit 511 estimates the name of the building included in the question and the name of the building included in the answer information, and the "name of the building estimated by the speech" and "predicted by the answer information" The name of the building to be displayed is a completely identical character string or a character string referring to the abbreviation of the same place, and the question answer matching degree W is calculated to be 100%, otherwise the question answer matching degree W is calculated to be 0%.

Further, as in the first embodiment, the driver is not limited to input the question of the route by the driver into the information providing control device 100 of the second embodiment. Further, the output from the output device 800 is not limited to the sound. Furthermore, the information providing function controlled by the information providing control device 100 is not limited to the function of performing path guidance. The information providing control device 100 according to the fifth embodiment of the present invention is a device for controlling an information providing function in an information providing device such as various devices that provide information, and can be widely applied. It can be used only from the information providing device proposed by the user. The degree of confidence in the tone of the question of the information provided and the information contained in the question and the information contained in the answer information of the question object can be calculated.

As described above, according to the second embodiment, the question determining unit 511 judges In the degree of comprehension, in addition to the degree of certainty estimated by using the tone of the question raised by the user, the question answer consistency W is also considered. Thereby, the information can be provided to the user with the level of detail of the information that better matches the user's understanding.

In the first and second embodiments, the detail level determining unit 512 changes the detail level of the output text and the output timing of the output text based on the degree of understanding determined by the question determining unit 511. However, the detail level determining unit 512 may change only. The detail level determining unit 512 may change the information amount of the output text based on the degree of understanding determined by the question determining unit 511.

Further, in the first and second embodiments, an example of the information providing device is the vehicle guiding device 600. However, the present invention is not limited to the vehicle guiding device for a vehicle, and the information providing device is a moving body (for example, it includes a person, a vehicle, a railway, A guiding device for use in a ship or aircraft, etc., which is particularly suitable for guiding devices that are suitable for being brought into or mounted in a vehicle.
