Description

The present invention relates to, for example, a system and a program including a control unit that outputs an access message to a user and starts voice recognition.

A system has been proposed in which a character displayed on a display screen communicates with a driver to assist the driver in driving. For example, Patent Document 1 proposes a system in which a user can perform various instructions such as route search and opening/closing of a power window while interacting with a character. A storage unit of the system stores an expected question of the user and a pattern of an answer of the character corresponding to the question, and guides a conversation while answering the question of the user to give various instructions. Unlike mere device operation, it is possible to make people feel an entertainment by operating in conversation with an anthropomorphic character.

If the conversation between the user and the character has one pattern, the entertainment property may be diminished by, for example, repeating the conversation many times. Therefore, different conversation patterns are stored according to multiple personalities such as social, positive, and introvert.

Japanese Patent No. 4798431

However, in the above-mentioned system, the conversation with the character is basically performed by the user to give an instruction to the system, and is basically passive in answering the questions from the user. Therefore, it is difficult to feel the individuality beyond one function of the system.

(1) The system according to the present invention has control means for outputting an access message to the user to start voice recognition when a predetermined condition is satisfied.

A system installed in an on-vehicle electronic device or the like usually operates by a user's button operation or voice input, but even if there is no user operation or input, by outputting a message for accessing the user from the system side, It is possible to give a surprise to the user, and it is possible to bring an added value that attracts the user in addition to the convenience. In particular, in a system that displays an animation of a character or outputs a voice, making a user feel a surprise makes the character more human and further arouses the purchase intention of the user who uses the system for the purpose of the character. be able to.

The “predetermined condition” may be, for example, the traveling distance or traveling time of the vehicle in which the vehicle-mounted electronic device is mounted. For example, by outputting an access message every 100 km of travel distance or every 3 hours of travel time, it is possible to give a stimulus to a drive that tends to be monotonous. The predetermined condition may be, for example, the traveling area of the vehicle in which the vehicle-mounted electronic device is mounted. For example, it is good to detect the position of the vehicle by GPS installed in the vehicle and output an access message when the vehicle moves from one prefecture to an adjacent prefecture. For example, the contents of the access message may be dialects or tourist information unique to the prefecture. In this way, the user can obtain useful information unique to the region, and possibly stimulate a monotonous drive. You can give it. The predetermined condition may be, for example, the number of times the system installed in the vehicle-mounted electronic device is activated or the number of times the voice recognition function is used. For example, when the number of system activations reaches a predetermined number, such as when the system has been activated 30 times or when the voice recognition function has been used 100 times, or when the voice recognition function has been used. If the access message is output when the number of times reaches a predetermined number, the motivation to use the system or voice recognition can be particularly agitated.

The “access message to the user” may be, for example, a message requesting a response from the user. The access message may be output, for example, as a utterance of the character. For example, in the case where an access message triggers a dialog with the user, the access message may be a message requesting permission to start the dialog, such as “Ah, can I talk now?”. Besides, for example, "Hello, now do I talk?" May include the words as a greeting, such as. In addition, it is preferable to include a nickname created according to the user's name input in advance, for example, "Yu-kun, can I talk now?" The access message may be output as voice, for example, through a speaker of the vehicle-mounted electronic device, or may be displayed as characters or image information on the display unit of the vehicle-mounted electronic device.

(2) If the user's response to the access message is affirmative, the control means may start a dialogue with the user by outputting predetermined information and recognizing the user's response to the information by voice recognition.

By accessing the user from the system side and further interacting with the system, it is possible to make the system, which tends to feel inorganic, to have a human touch, and further increase the added value of the system. In addition, by starting a dialogue with the user in response to the content of the response to the access message from the user, while giving a surprise to the user, the subsequent scenarios can proceed in consideration of the user's convenience. It is possible to prevent the user from feeling annoying.

By starting the dialog only when the user gives a positive response, it is possible to prevent the scenario from progressing and causing the user to feel annoyed. Therefore, it is particularly useful in a system in which a character on the system side advances a dialogue based on a stored scenario. Further, when the character is used, the user can be made to feel the modesty of the character.

The “dialogue with the user” is, for example, voice recognition of a user's response to predetermined information output by the system, and further output of further information according to the content. For example, the system outputs information sufficient for the user to feel that the communication is established. The information may be output as, for example, the utterance of the character.

The predetermined information forming the dialogue may be composed of a plurality of phrases such as a question, a thank-you note, and an exclamation point. The plurality of phrases may include, for example, at least one question, and may prompt the user to give either a positive or negative response. What is combined with the question may be, for example, a word of emotion expression or a thank-you note that represents the character of the character, and may be a word unrelated to the original function of the system. The plurality of phrases may be output as the character's statement. For example, the following statement may be output.
・"Ah~, thank you for buying my Navi this time. I wonder if you like it?
・"I was a little free. I sometimes talk to you like this.
・“Thank you for using it a lot. I want to give a thank you song as a gift.

For example, the system may store in advance a word or phrase that is supposed as a response content of the user in the storage means. Words may be classified as either "positive" or "negative", for example. As a positive word, for example, “yes”, “yes”, “ok”, “good”. As a negative word, for example, "No", "No", "No", "Noisy", "No". If it does not correspond to the stored phrase, it is good to treat it as unrecognizable.

Furthermore, it is preferable to store the word/phrase assumed as the response content of the user in the “dialogue” in the storage means in advance. Words may be classified as either "positive" or "negative", for example. Since there are a plurality of types of information output by the system in the "dialogue", it is better to store more words and phrases in the "dialogue" stage than in the access message output stage.

As a positive phrase, for example, “yes”, “yes”, “ok”, “is good”, “is like”, “is like”, “is like”, “knows”, and “is understood”. Negative phrases include, for example, "No", "No", "No", "Noisy", "No", "No", "No", "No", "No", "No", "No" Is good.

The system may select the information to be output next depending on whether the user's response to the output information is “positive” or “negative”.

If the user does not respond to the access message, or if the response contents cannot be recognized by voice, for example, a reminder message prompting the user to respond may be output a predetermined number of times at predetermined intervals. The prompt message prompting the user to respond may be, for example, "Hey, say something" or "I'm sad if you don't say something" when there is no response. If the voice cannot be recognized, for example, "I don't know what I said. I'll say it again." If the user does not respond to the reminder message within the predetermined time, for example, a termination message such as "see you next time" may be output to cancel the voice recognition.

(3) When the user's response to the access message is negative, the control unit may output information including a notification that the dialogue with the user is not started, and terminate the voice recognition.

By not starting the dialogue when the user's response is negative, it is possible to prevent the scenario from progressing and causing the user to feel annoyed. When using a character, the user can be made to feel the modesty of the character. For example, if the user outputs a negative response "No, can I speak now?" as an access message and the user makes a negative response "No", then "I'm sorry. See you next time" It is good to output a statement.

(4) In the dialog with the user, the control means may output information including notification of the end of the dialog, and start a predetermined event after the dialog with the user ends.

A predetermined event is started after the end of the interaction with the user, that is, the interaction with the user triggers the start of the predetermined event, for example, to motivate the user to have an interaction and increase attachment to the system. it can.

The end of the dialogue with the user may be, for example, end of information output and cancellation of voice recognition. The “notification of end of dialogue” may be, for example, to inform the user that the dialogue with the character is finished. For example, a combination of words of thanks and ending greetings may be output as the character's statement. For example, the following statement may be output.
・"Thank you. I'm glad. Please use it from now on. Next time again"
・"Really?I'll talk again."

The “predetermined event” may be, for example, new information, character information, or a combination of these information. For example, it may be image information in which the character wears a new costume. Further, for example, it may be moving image information in which the character sings a song or dances. A plurality of predetermined events may be stored in the storage means of the system. As the predetermined event, the predetermined event to be started may be determined according to a combination of the information output to the user and the user's response to the information. Alternatively, the predetermined event to be started may be determined in accordance with the time condition such as a season or an annual event and the condition of a place such as a traveling area of the vehicle.

(5) In the dialog with the user, the control means outputs information including a question asking for permission to start a predetermined event, and includes notification of dialogue end when the user's response to the information is affirmative. It is advisable to output information and start a predetermined event after the dialogue ends.

For example, if the predetermined event is a moving image of a character, it may take time to display all the moving images. Therefore, before the moving image is displayed, the user is asked whether or not the moving image can be displayed, and the response the user wants to display. By starting the event only when the user performs the operation, the system can be made convenient for the user. For example, the inquiry information requesting permission to start a predetermined event and the user's positive response to the information may be set as follows.
・Inquiry information asking for permission to start a predetermined event: "There is a special dance, can I show it now?"
・User's positive response: “Yes”, “Yes”, “Okay”, “Good”, “Thank you”

(6) In the dialog with the user, the control means outputs information including a question asking for permission to start a predetermined event, and when the user's response to the information is negative, a notification of the end of the dialog and a predetermined notification are given. It is advisable to notify the event start condition and end the dialogue.

For example, if the predetermined event is a moving image of a character, it may take time to display all the moving images. Therefore, the user is asked whether or not the moving image can be displayed before the moving image is displayed, and the user does not want to display the moving image. When a response is given, the user can watch the moving image at any time by notifying the displaying condition of the moving image, instead of displaying the moving image, and the system is convenient for the user. For example, the inquiry information asking for permission to start a predetermined event, the user's negative response to the information, the notification of the dialogue end, and the notification of the predetermined event start condition may be performed as follows.
・Inquiry information asking for permission to start a predetermined event: "There is a special dance, can I show it now?"
・Negative response from the user: "No. I'm driving now."
・Notification of dialogue end and predetermined event start condition: "Okay. I will keep the image in the event log, so please access it at any time. See you later."

(7) When the predetermined event starts, the control means may display the character on the display means in a size that hinders the function of the system.

The predetermined event gives a big surprise to the user by displaying the image information of the character by ignoring the original functions such as the radar detector and the car navigation and displaying the character with the momentum to hijack the screen. You can

Displaying in a size that hinders the function of the system may be displayed, for example, so as to cover the image already displayed on the display unit.

(8) The control means may display a mark indicating that the character is about to listen to the voice of the user on the display means when starting the voice recognition.

When voice recognition is started, for example, an image in which the character wears a headset or an image in which the character makes a gesture to listen to may be displayed on the display unit of the vehicle-mounted electronic device. The user can have an impression that the character is listening to his/her voice, and can easily become familiar with the character. Further, it is easy to visually confirm that the voice recognition function is operating, which is highly convenient.

(9) The control unit may delay the output of the access message until the control condition is not satisfied even when the control condition is satisfied even when the predetermined condition is satisfied.

If the user is in a situation that should be prioritized over the dialogue, for example, even if the predetermined mileage is exceeded, for example, if the acceleration condition detected from OBD is high, access message until the acceleration condition becomes low. By delaying the output of, the safety is high without impeding the ability to concentrate on driving.

Suppression conditions are, for example, that route guidance, which is the original function of the system installed in in-vehicle electronic devices, is being performed, that voice recognition is being performed, that an alarm voice is being generated, and that other voice is being generated. It is preferable that the character display mode is not set, the vehicle is traveling at 100 km/h or more, and so on.

According to the present invention, for example, a surprise can be given by accessing the user from the system side regardless of the user's operation. Further, it is possible to provide an excellent system that makes the system feel human, amplifies the attachment to the system, and stimulates the purchase will.

The following devices and parts are arranged inside the case body 4. That is, the microwave receiver 11 is arranged inside the back side of the case body 4. The microwave receiver 11 receives microwaves in a predetermined frequency band, and when receiving microwaves in the set frequency band, detects the signal level of the received microwaves. Specifically, the RSSI voltage that is the signal level and corresponds to the electric field strength is used. The above-mentioned predetermined frequency band is a frequency band including the frequency of the microwave emitted from the vehicle speed measurement device, for example.

A GPS receiver 12 that receives a GPS signal and obtains the current position is arranged inside the upper surface of the case body 4. An infrared communication device 14 is arranged inside the front surface of the case body 4. The infrared communication device 14 transmits/receives data to/from a communication device such as a mobile phone 15 having a built-in infrared communication device. Further, a speaker 20 is built in the case body 4.

Further, the apparatus of this embodiment includes a wireless receiver 13 and a remote control receiver 16. The wireless receiver 13 receives incoming radio waves of a predetermined frequency. The remote control receiver 16 performs data communication with a remote control (portable device: slave device) 17 and makes various settings for the device. The radio receiver 13 receives incoming radio waves in a predetermined frequency band. The predetermined frequency may be, for example, a wireless frequency band used by the emergency vehicle to notify the base station of its own vehicle position.

In addition to the navigation function, the navigation device 1 of the present embodiment also has a target object notification function as a target object notification device for notifying a target object such as a vehicle speed measuring device and other traffic monitoring points existing in the vicinity. The navigation function and the target notification function are stored in the EEPROM of the control unit 18 as a program executed by the computer included in the control unit 18, and are realized by the computer included in the control unit 18 executing the program.

That is, the control unit 18 controls the above various input devices (GPS receiver 12, microwave receiver 11, wireless receiver 13, touch panel 8, infrared communication device 14, remote control receiver 16, SD memory card slot unit 21, Predetermined processing is executed based on information input from the USB terminal 23 or the like), and output devices (display unit 5, alarm lamp 9, speaker 20, infrared communication device 14, SD memory card slot unit 21, USB terminal 23, etc.) To output predetermined information/warning/message. This predetermined processing is for executing the above-mentioned functions, and accesses the database 19 and the SD memory card 22 as necessary.

Here, the database 19 can be realized by a non-volatile memory (for example, EEPROM) inside or outside the microcomputer of the control unit 18. Note that the database 19 stores certain target objects and information necessary for carrying out each function such as a map at the time of shipment, and data etc. regarding the target objects added after that are subjected to predetermined processing. Can be updated over time. The update process may be performed by, for example, mounting the SD memory card 22 storing the additional data in the SD memory card slot portion 21 and transferring the SD memory card 22 from the SD memory card 22 to the database 19. .. Further, this data update can be performed by using the infrared communication device 14 or a personal computer or other external device connected via the USB terminal 23.

The control unit 18 for realizing the target object notification function operates as follows. That is, the control unit 18 outputs a predetermined alarm when the microwave receiver 11 receives a desired microwave. As this alarm, a buzzer using the speaker 20 or a voice output for notifying reception of microwaves (detection of the vehicle speed measuring device, etc.), lighting of the alarm lamp 9, and characters or images using the display unit 5 are used. There are message output etc.

In addition, the control unit 18 outputs a predetermined alarm when the wireless receiver 13 receives a desired wireless. Examples of the alarm include a buzzer using the speaker 20 and a voice output for notifying the reception of microwaves (approach of an emergency vehicle, etc.) and a message output by characters or images using the display unit 5. It is preferable that the alarm associated with the reception of the radio wave and the alarm associated with the reception of the microwave are different in form.

Further, the control unit 18 outputs a predetermined alarm when the current position detected by the GPS receiver 12 and the position of a target object such as a traffic monitoring point stored in the database 19 have a predetermined positional relationship. .. Therefore, the database 19 is safer with more attention such as information about the target object to be detected (positional information of the target object including longitude and latitude, target object type information, etc.), accident-prone zones, traffic control information, etc. There are traffic safety information for driving, and various information useful for landmarks and driving. Each information is registered by associating a specific information type (type of target, type of traffic crackdown, accident-prone zone, name of landmark, etc.) with position information.

The distance to the target when the alarm is issued can be changed for each type of target. Similar to the above, examples of the warning include a warning by voice or the like using the speaker 20 and a warning using the display unit 5. FIG. 3 shows an example of an alarm by the display unit 5. In the present embodiment, since the device is the navigation device 1, since it has map data as will be described later, the control unit 18 reads the road network information around the current position as a basic screen and The display unit 5 has a function of displaying the map. Then, the warning screen 70 is displayed on the display unit 5 so as to be superimposed on the currently displayed screen (here, the map around the current position). FIG. 3 is a display example of the warning screen 70 when the distance between the current position and the LH system, which is a type of speed measurement device that is one of traffic monitoring points, is 500 m when the map 50 is displayed. Is shown. Further, a process of outputting a warning voice indicating the alarm type and distance such as “500 m ahead LH system” from the speaker 20 is performed.

On the other hand, the control unit 18 for realizing the navigation function operates as follows. First, the database 19 stores road network information for navigation. The information for navigation stored in the database 19 may be all information about the whole country at the time of shipment, and map data etc. provided in the SD memory card 22 for each region. The user may prepare the SD memory card 22 in which necessary map data and the like are stored, and attach the SD memory card 22 to the SD memory card slot 21 for use. The map data and the like stored in the SD memory card 22 may be transferred to and stored in the database 19, or the control unit 18 may access the SD memory card 22 and read from there for use. good.

The control unit 18 has a function of reading road network information around the current position from the database 19 and displaying a map around the current position on the display unit 5. The control unit 18 can search for a route from one position to another position by using the road network information. Further, the database 19 stores a telephone number database in which a telephone number is associated and stored with location information and names of houses, companies, facilities, etc. of the telephone number, and an address and location information of the address are associated with each other. It has an address database. The database 19 also stores the position information of traffic monitoring points such as speed measuring devices together with their types.

Further, the control unit 18 has a function of performing processing of the general navigation device 1. That is, a map around the current position is displayed on the display unit 5 at any time, and a destination setting button is displayed. The control unit 18 performs the destination setting process when the touch panel 8 detects a touch at a position corresponding to the display position of the destination setting button. In the destination setting process, a destination setting menu is displayed on the display unit 5 to prompt the user to select a destination setting method. The destination setting menu has a telephone number search button and an address search button that prompt the user to select a destination setting method. When it is detected that the telephone number search button is touched, the telephone number input screen is displayed, and the positional information corresponding to the input telephone number is acquired from the database 19. When it is detected that the address search button is touched, an address selection input screen is displayed, and position information corresponding to the input address is acquired from the database 19. Then, the acquired position information is set as the position information of the destination, and the recommended route from the current position to the destination is obtained based on the road network information stored in the database 19. As a method of calculating this recommended route, a known method such as the Dijkstra method can be used.

Then, the control unit 18 displays the calculated recommended route together with the surrounding map. For example, as shown in FIG. 4, the route 53 from the current position 51 to the destination 52 is displayed as a recommended route in a predetermined color (for example, red). This is similar to a general navigation system. Then, in the present embodiment, the control unit 18 compares the position information on the route 53 with the position information of the target object such as the traffic monitoring point stored in the database 19 to determine the position of the traffic monitoring point or the like on the route 53. Display position. In addition, the provision of information for driving safely on the route 53 may be limited to traffic monitoring points among various targets stored in the database 19.

Thereby, for example, as shown in FIG. 4, a balloon is displayed from a position on the road, and the type of traffic monitoring point at that position stored in the database 19 is displayed in the balloon. For example, FIG. 4A is a display example of the warning point search screen, and shows an example in which the traffic monitoring points 55a to 55f are displayed. The traffic monitoring point 55a displays the letter "N" indicating the N system in a balloon. The traffic monitoring points 55b, 55c, 55e display the letters "LH" indicating the LH system in balloons. The traffic monitoring point 55d displays the characters "loop" indicating a loop coil in a balloon. The traffic monitoring point 55f displays the letter "H" indicating the H system in a balloon. In this way, when the touch panel 8 detects a touch on the balloon position in the simplified display state where characters are displayed in the balloon, the simplified display is switched to the detailed display as shown in FIG. 4B. The detailed display displays the warning screen shown in FIG. 3 in a balloon.

Further, as shown in FIG. 4A, a traffic monitoring point type designation unit 56 is displayed on the lower right side of the display unit 5. The traffic monitoring point type designation unit 56 is a part that displays a button listing the types of traffic monitoring points existing on the route 53. In the example of FIG. 4A, an “N” type button 57a indicating the N system of the traffic monitoring point 55a, an “LH” type button 57b indicating the LH system of the traffic monitoring points 55b, 55c, 55e, and a traffic A "loop" type button 57c indicating the loop coil of the monitoring point 55d and an "H" type button 57d indicating the H system of the traffic monitoring point 55f are displayed. When the control unit 18 detects the touch of the type button on the display unit 5 from the touch panel 8, the control unit 18 reversely displays the touched type button and displays the display mode of the traffic monitoring points corresponding to the touched type button. If the simple display is being performed, the display is switched to the detailed display, and if the detailed display is being performed, the display is switched to the simple display.

The car navigation device 1 of the present embodiment has a peripheral search function as a method of setting a destination (hereinafter, also including a waypoint). When this peripheral search function is selected and activated, the control unit 18 extracts a facility that matches the specified conditions and is close to the current position, and draws the extraction result on the display unit 5. Then, the user can designate any one of the candidates drawn on the display unit 5 as a destination (including a waypoint) by confirming the selected one.

That is, in order to realize such a function, the database 19 of the present embodiment stores the information about each facility in association with the position information and the information about the classification of the facility. The information on the classification of facilities is a plurality of types of items that are grouped by the names of genres that each facility matches.

In the present embodiment, when any of the items is designated, the control unit 18 extracts a facility that matches the designated item and is close to the current position, and uses the extraction result as a destination candidate. Drawing on the display unit 5. The user can designate as a destination by selecting any one of the candidates drawn on the display unit 5.

When any one of the items is selected, the control unit 18 accesses the database 19 and is a facility existing within a reference distance (for example, 10 km) around the current position, and matches the classification of the designated item. Extract what you want to do. Then, a predetermined number (for example, 10) of facilities from the closest one is drawn on the corresponding portion of the map drawn on the display unit 5 so as to overlap the icon (mark) indicating the facility. As the facility information stored in the database 19, each icon is registered in association with each facility, and at the time of drawing, the associated icon is read and drawn at a predetermined position on the display unit 5.

When the current position is present on the map drawn on the display unit 5, the own vehicle icon indicating the own vehicle is drawn so as to overlap the position corresponding to the current position. Furthermore, when drawing the icon of such a facility, numbers are added and displayed in order from the vehicle closest to the vehicle. The number will be updated as the vehicle moves.

Then, when the user selects a desired facility, the control unit 18 recognizing the desired facility obtains a recommended route having the facility as a destination, and draws the result on the map of the display unit 5.

Further, the control unit 18 has a function of performing route guidance to the set destination. That is, the control unit 18 draws map information representing roads and the like on the display unit 5 while sequentially detecting the vehicle position by GPS or autonomous navigation in accordance with the selection of guidance start by the user, and reaches the destination. Provides directions by using images and sounds.

To input instructions such as designation and selection by the user described above, a button on which a name of an item or a function is displayed on the display unit 5, a facility icon is touched, a remote control is selected, or a predetermined voice is input. This can be done when the control unit 18 detects it.

Hereinafter, a dialogue function with a character, which is a feature of this embodiment, will be described. This interactive function is a function realized by the control unit 18 executing a program. The interactive function, for example, activates the voice recognition according to the user's operation or input, and then performs the system original functions such as peripheral search, scale change, volume change, and brightness change according to the phrase input by the user. There is a function to demonstrate it.

The interactive function of the present embodiment further realizes a dialog with the user by outputting an access message from the system side regardless of the user's operation or input. This gives a surprise to the user and provides entertainment to the navigation device 1, which tends to be inorganic.

<<Interactive function example 1>>
FIG. 5 shows an example of the interactive function realized in this embodiment. The control unit 18 outputs the access message (step S02) and activates the voice recognition at the same time, regardless of the user's operation or input, with the trigger that the access message output condition is satisfied (step S01: Yes). S03). Only when the user's response to the access message is affirmative (step S04: Yes), the control unit 18 outputs the dialogue message and starts the dialogue with the user (step S05). The dialogue consists of outputting a dialogue message from the control unit 18 and a user's response to the dialogue message. The dialogue message has a plurality of patterns, and the dialogue may be terminated by one output and the user's response, or the dialogue message may be overlapped with the plurality of outputs and the user's response. When ending the dialogue, the control unit 18 outputs an end message (step S06) and ends the voice recognition (step S07).

If the user's response to the access message is negative in step S04 (step S04: No), the control unit 18 immediately outputs the end message (step S08) and ends the voice recognition (step S09). .. That is, the control unit 18 interacts with the user only when the user wants to interact with the system.

In step S04 and step S05, when there is no response from the user or when the response content cannot be recognized by voice, for example, a reminder message prompting the user to respond is output a predetermined number of times at predetermined intervals. It is good to set. If you receive a response to the reminder message, proceed to the next step. If the user does not respond to the reminder message within the predetermined time, it is preferable to output an end message and end the voice recognition.

In order to realize the above interactive function, the database 19 corresponds to an access message output condition (hereinafter, also simply referred to as “output condition”), an access message, a recognition word for recognizing a response by the user's voice, and a recognition word. It stores data such as dialogue messages, end messages, and reminder messages. In addition, data necessary for realizing the system functions are stored as appropriate. The control unit 18 refers to the database 19 and executes steps S01 to S09 described above.

≪Access message output condition≫
The access message output condition may be set, for example, when the travel distance, travel time, and travel area of the vehicle equipped with the navigation device 1 satisfy predetermined conditions. For example, the control unit 18 may acquire information from the odometer of the vehicle and output an access message every 100 km of travel distance or every 3 hours of travel time. Further, for example, it is preferable to detect the position of the vehicle by GPS installed in the vehicle and output an access message when the prefecture moves from one prefecture to an adjacent prefecture. The access message output condition may be, for example, the number of times the system installed in the navigation device 1 is activated or the number of times the voice recognition function is used. For example, the access message may be output when the system is first activated, when the number of activations reaches 30, or when the voice recognition function is used 100 times.

However, even when the access message output condition is satisfied, it may not be desirable to output the access message depending on the state of the vehicle or the navigation device 1. It is advisable to save the state in which it is not desirable to output the access message in the database 19 as a suppression condition. Even if the access message output condition is satisfied, the control unit 18 may delay the output of the access message until the suppression condition is not satisfied, when these suppression conditions are satisfied.

The suppression conditions are, for example, that the acceleration detected from the OBD is a predetermined value or more, that route guidance is being performed, that voice recognition is being performed, that other voice is being generated, that it is not in character display mode, 100 km/h or more. It is good to say that you are running in.

≪Access message≫
The access message may be, for example, a message requesting a response from the user. The access message may be output, for example, as a utterance of the character. Further, it is preferable that the subsequent messages are also output as the utterance of the character. This allows the user to easily interact with the character by using the electronic device that is the system. The character of this embodiment is set as, for example, a girl named "Ray". Various functions such as the above peripheral search can also be performed by dialogue with the character. The database 19 stores "Letan" as a recognition word as a character name.

When the message is made as a character's utterance, the database 19 stores voice data and image (including still image and moving image) data of the character. The control unit 18 can display a still image and a moving image of the character on the display unit 5 based on the image data. It should be noted that the control unit 18 realizes, for some response phrases, a situation in which the character is speaking by a lip link that moves the mouth or body of the character displayed on the display unit 5 so as to match the output response phrase. Can make you feel.

Further, as the voice and image of the character stored in the database 19, a plurality of modes (modes) are set for the same person. For example, the database 19 is a single person named “Ray” but is divided into three modes of “standard ray”, “ray after transformation”, and “chibi ray”, and stores each response phrase and image data. doing. "Standard Ray" is the basic mode of the character. "Ray after transformation" is a mode in which clothes and hairstyle are changed from "standard ray". "Chibi Rei" is a childish mode in which you change your head and body. The control unit 18 outputs the voice and the image of the character according to the selection of any mode by the user.

The access message may be, for example, a message requesting permission to start a dialogue such as "Are you sure you want to speak now?" "Are you talking now?". Besides, for example, "Hello, now do I talk?" May include the words as a greeting, such as. In addition, it is preferable to include a nickname created according to the user's name input in advance, for example, "Yu-kun, can I talk now?" The user's name may be input, for example, from various system setting screens. For example, different access messages may be prepared for each output condition. The control unit 18 may output the access message by voice, for example, via the speaker 20 of the navigation device 1. In addition, for example, it may be displayed on the display unit 5 of the navigation device 1 by characters or image information.

≪Dialogue message≫
The dialogue message may include, for example, information sufficient for the user to feel that the communication is established. The dialogue message may be output as, for example, a character's statement. The information included in the dialogue message is not limited to a particular one, but may be a plurality of phrases such as a question, a thank-you note, or an exclamation point. The plurality of phrases may include at least one question, for example, and may prompt the user to give either a positive or negative response. The phrase combined with the question may be, for example, a word of emotional expression or a thank-you note that represents the character of the character, or a word that gives a human touch apart from the original function of the system. The plurality of phrases may be output as the character's statement. For example, the following statement may be output.
・Example of dialogue message "Well, thank you for buying my Navi this time. Do you like it? I'm a little worried."
"I was a little free. I sometimes talk to you like this.

When the interactive message is output multiple times, the output message may be different depending on the response content of the user, as shown in the following example.
・Dialogue example 1
First dialogue message: "Thank you for buying my Navi this time. I hope you like it? I'm a little worried."
User Response: "I like it"
Next dialogue message: "I'm happy! Can I talk to you again?"
・Dialogue example 2
First dialogue message: "Thank you for buying my Navi this time. I hope you like it? I'm a little worried."
User Response: "I don't like"
Next dialogue message: "Oh, sorry. But can I talk to you again?"

The control unit 18 may output the dialogue message as voice, for example, via the speaker 20 of the navigation device 1. In addition, for example, it may be displayed on the display unit 5 of the navigation device 1 by characters or image information.

≪Voice recognition≫
When the voice recognition is started, the control unit 18 displays on the display unit 5 of the navigation device 1 a mark indicating that the character is about to listen to the user's voice on a display means that should be displayed by characters or image information. Should be displayed.

When the voice recognition is started, for example, a mark indicating that the character is about to hear the user's voice may be displayed on the display unit 5 of the navigation device 1. As such a mark, for example, an image in which the character wears a headset, an image in which the character makes a gesture to listen, or the like may be displayed.

<<recognition word>>
The recognition word is, for example, a word or phrase assumed as the content of a user's response to an access message or an interactive message described later. The recognition words may be classified into a group of “positive” words and a group of “negative” words, for example. The control unit 18 determines whether the response content of the voice-recognized user is a positive one or a negative one of the stored recognition words to determine whether to start a dialogue, or Determines the content of the dialogue message of. The positive word for the access message may be, for example, “yes”, “yes”, “ok”, or “good”. As a negative word, for example, "No", "No", "No", "Noisy", "No" is good. The control unit 18 performs voice recognition on the response content of the user, determines whether the word is “positive” or “negative”, and performs the next process. If the stored word does not correspond to the word, a word or phrase that prompts the user to re-input, such as "I'll say it again?"

Furthermore, it is preferable to store the words and phrases expected as the contents of the user's response to the dialogue message in the storage means in advance. For example, the words may be stored so as to be classified as either “positive” or “negative”. Since there are a plurality of types of information output by the system in the "dialogue", it is better to store more words and phrases in the "dialogue" stage than in the access message output stage. The dialog message to be output next may be selected depending on whether the user's response is positive or negative.

As a positive phrase, for example, “yes”, “yes”, “ok”, “is good”, “is like”, “is like”, “is like”, “knows”, and “is understood”. Negative phrases include, for example, "No", "No", "No", "Noisy", "No", "No", "No", "No", "No", "No", "No" Is good. However, the words "Yes" and "No" may be affirmative or negative depending on the content of the question. For example, it is affirmative to answer "No" to the question "I sometimes talk to you like this, but are you sorry?" Therefore, the recognition word and the classification are stored in association with the question included in each dialogue message, and control is branched based on the stored classification to either a positive process or a negative process. Good to do.

≪End message≫
The end message is a message that is output at the timing of ending the output of the interactive message and canceling the voice recognition. The end message may be, for example, to inform the user that the dialogue with the character is finished. For example, a combination of words of thanks and ending greetings may be output as the character's statement. The end message may also include a reaction to the user's response in the immediately previous dialogue.
-Example 1 of end message
Dialogue message: "Thank you for buying my Navi this time. Do you like it? I'm a little worried."
User Response: "I like it"
End message: "Thank you. I'm glad. Please use it from now on. Next time again."
-Example 2 of end message
Dialogue message: "Thank you for buying my Navi this time. Do you like it? I'm a little worried."
User Response: "I don't like it"
Closing message: "Shock. Please use it from now on. Next time again."
-Exit message example 3
Dialogue message: “I was a little free. I sometimes talk to you like this.
User Response: "No"
End message "Really? I'll chat again."

The end message is also output when the user's response to the access message is negative (step S04: No) and the dialogue is not started. The end message in this case may include a notification that the dialogue with the user is not started. The end message may also include contents indicating an apology for disturbing the user and a disappointment for rejecting the conversation by the user.
・Example 1
Access message: "Um, can I speak now?"
User Response: "No"
Closing message: "I'm sorry. Then, next time again."
・Example 2
Access message: "Are you sure you want to talk now?"
User: "Noisy"
End message: "Uu ww, see you next time"

The control unit 18 may output the end message by voice, for example, via the speaker 20 of the navigation device 1. In addition, for example, it may be displayed on the display unit 5 of the navigation device 1 by characters or image information.

≪Reminder message≫
The reminder message is a reminder message that prompts the user for a response. When the user does not respond to the access message and the dialogue message, or when the response contents cannot be recognized by voice, the control unit 18 issues a reminder message at predetermined intervals such as every 30 seconds, for example, three times. It is preferable to output the predetermined number of times. The prompt message prompting the user to respond may be, for example, "Hey, say something" or "I'm sad if you don't say something" when there is no response. If the voice cannot be recognized, for example, "I don't know what I said. I'll say it again." When the user does not respond to the reminder message within the predetermined time, the end message may be, for example, "see you next time".

<<Interactive function example 2>>
FIG. 6 shows another example of the interactive function realized in this embodiment. In another example, the control unit 18 triggers the event triggered by the interaction with the user. Steps S11 to S15 are the same as steps S01 to S05 in FIG. The control unit 18 outputs a dialogue message, and after the dialogue of the control unit 18 having the dialogue with the user, outputs the inquiry for permission to start the event (step S16). When the user's response to the question asking for permission to start the event is affirmative (step S17: Yes), the control unit 18 outputs an end message (step S18) and ends the voice recognition (step S18). After step S19), the event is started (step S20).

When the user's response to the inquiry for permission to start the event is negative (step S17: No), the control unit 18 outputs an end message (step S21) and ends the voice recognition. (Step S22), however, the event is not started thereafter, and the process ends.

≪Event≫
The event may be new information, character information, or a combination of these information. For example, it may be image information in which the character wears a new costume. Further, for example, it may be moving image information in which the character sings a song or dances. It is preferable to store a plurality of such event image, moving image, and audio data in the database 19. The control unit 18 may display the image or moving image of the event stored in the database 19 on the display unit 5 and output it from the speaker 20.

The event may be determined, for example, according to the access message output condition that triggers the start of the dialogue. For example, when the mileage reaches 100 km, the character is wearing new clothes, and when the mileage reaches 200 km, the character sings or dances. It would be nice if the event became more gorgeous.

For example, the control unit 18 may determine the predetermined event to be started according to the combination of the information output to the user, which is the content of the dialogue, and the user's response to the information. For example, the interactive message may be output multiple times, and the event to be output may be changed depending on the combination of whether the user's response to each interactive message is positive or negative. For example, in the case of the following dialogue example 1, the event may be an image of a character wearing a new costume and dancing. Also, for example, in the case of the following dialogue example 2, the event may be an image of a character who has a new costume but has a somewhat disappointing expression. Further, for example, in the case of the following dialogue example 3, it is preferable that the costume is a conventional one and the image is a character having a depressed expression.
・Dialogue example 1
First dialogue message: "Thank you for buying my Navi this time. I hope you like it? I'm a little worried."
User Response: "I like it"
Next dialogue message: "I'm happy! Can I talk to you again?"
User Response: "OK"
・Dialogue example 2
First dialogue message: "Thank you for buying my Navi this time. I hope you like it? I'm a little worried."
User Response: "I don't like"
Next dialogue message: "Oh, sorry. But can I talk to you again?"
User Response: "OK"
・Dialogue example 3
First dialogue message: "Thank you for buying my Navi this time. I hope you like it? I'm a little worried."
User Response: "I don't like"
Next dialogue message: "Oh, sorry. But can I talk to you again?"
User Response: "No"

Further, the event may be changed in accordance with a time condition such as a season or an annual event or a condition of a place such as a traveling area of the vehicle. For example, if the season is spring, an image of a character standing under a cherry tree may be used. Also, for example, if Valentine's Day is near, it may be an image in which the character has chocolate. In addition, for example, if you are traveling in Yokohama, it is good to use an image of a character with the cityscape of the Minato Mirai district as the background.

The character displayed on the display unit 5 at the event may have a size that hinders the function of the system, for example. Usually, the character is often displayed so as not to disturb the menu screen or the map information displayed on the display unit 5 according to the function of the system. On the other hand, in the event, the menu screen displayed on the display unit 5 may be displayed in a size large enough to cover the menu screen.

The event for which the start is decided may be, for example, so that the event can be reviewed later when desired by the user. For example, an event log function may be provided, and the control unit 18 may record the event whose start has been decided in the event log. The user can review the desired event by accessing the event log.

≪Inquiry for permission to start the event≫
The question asking for permission to start the event is, for example, if the event is a video of a character, whether or not to permit the user to display the video, "There is a special dance, can I show it now?" It is good to ask that question. It may take some time to display all the videos. By starting the event only when the user makes a reply desired to be displayed, the system can be made convenient for the user.

≪End message≫
Similar to the interactive function example 1, the control unit 18 may output the end message at the timing of canceling the voice recognition. In the interactive function example 2, since the message is output after the inquiry for permission to start the event, the content of the end message may be changed depending on whether the user's response to the inquiry is positive or negative. If the user's response is positive, the end message may include an announcement of the start of the event. If the user's response is negative, the event start condition may be included in the end message. The event start condition may be, for example, a condition that allows the user to start the event when it is convenient, and may be access to an event log in which the event for which the start is determined is recorded. An example of the end message is shown below.
-Example when user response is positive:
Asking for permission: "I have a special dance, can I show it now?"
User Response: "OK"
End message: "Thank you. I'm glad. See you!"
• Example when the user response is negative:
Asking for permission: "I have a special dance, can I show it now?"
・Negative response from the user: "No. I'm driving now."
・End message "Okay. I will keep the image in the event log, so please access it at any time. See you later."

[effect]
The above-described present embodiment has the following effects.
(A) When the access message output condition is satisfied, the control unit 18 of the navigation device 1 outputs an access message to the user and starts voice recognition. The navigation device 1 normally operates by a user's button operation or voice input, but even if there is no user's operation or input, the device can output a message for accessing the user to give a surprise to the user. it can. As a result, it is possible to provide added value that attracts the user, in addition to the convenience. In particular, in the navigation device 1 that performs animation display and voice output of a character in functions such as route guidance, making the user feel a surprise makes the character more human, and the navigation device is aimed at the character. It is possible to arouse the purchase will of the user who uses 1.

The access message output condition may be, for example, the travel distance or travel time of the vehicle in which the navigation device 1 is mounted. For example, by outputting an access message every 100 km of travel distance or every 3 hours of travel time, it is possible to give a stimulus to a drive that tends to be monotonous. The access message output condition may be, for example, the traveling area of the vehicle in which the navigation device 1 is mounted. For example, it is good to detect the position of the vehicle by GPS installed in the vehicle and output an access message when the vehicle moves from one prefecture to an adjacent prefecture. By making the contents of the access message a dialect or tourist information specific to the prefecture, the user can obtain useful information, and can give a stimulus to a drive that tends to be monotonous. The access message output condition may be, for example, the number of times the navigation device 1 is activated or the number of times the voice recognition function is used. For example, when the system is activated 30 times or when the voice recognition function is used 100 times, an access message is output to motivate the user to use the system or voice recognition. ..

The “access message to the user” may be, for example, a message requesting a response from the user. The access message may be output, for example, as a utterance of the character. For example, in the case where an access message triggers a dialog with the user, the access message may be a message requesting permission to start the dialog, such as “Ah, can I talk now?”. Besides, for example, "Hello, now do I talk?" May include the words as a greeting, such as. In addition, it is preferable to include a nickname created according to the user's name input in advance, for example, "Yu-kun, can I talk now?" The access message may be output as voice, for example, through the speaker 20 of the navigation device 1, or may be displayed on the display unit 5 of the navigation device 1 as characters or image information.

(B) When the content of the user's response to the access message is affirmative, the control unit 18 starts a dialogue with the user by voice recognition of a dialogue message that is a predetermined information output and the user's response to the dialogue message. good.

By accessing the user from the navigation device 1 side and further interacting with the user, it is possible to make the device, which tends to feel inorganic, to have a human touch, and further increase the added value of the navigation device 1. In addition, by starting a dialogue with the user in response to the content of the response to the access message from the user, while giving a surprise to the user, the subsequent scenarios can proceed in consideration of the user's convenience. It is possible to prevent the user from feeling annoying.

By starting the dialog only when the user gives a positive response, it is possible to prevent the scenario from progressing and causing the user to feel annoyed. When using a character, the user can be made to feel the modesty of the character.

The “dialogue with the user” is, for example, voice recognition of the user's response to the dialogue message output by the system, and further output of a dialogue message according to the content of the response. For example, the navigation device 1 may output a dialogue message sufficient for the user to feel that the communication is established. The dialogue message may be output as, for example, a character's statement.

The dialogue message constituting the dialogue may be composed of a plurality of phrases such as a question, a thank-you note, and an exclamation point. The plurality of phrases may include, for example, at least one question, and may prompt the user to give either a positive or negative response. What is combined with the question may be, for example, a word of emotion expression or a thank-you note that represents the character of the character, and may be a word unrelated to the original function of the system. The plurality of phrases may be output as the character's statement. For example, the following statement may be output.
・"Ah~, thank you for buying my Navi this time. I wonder if you like it?
・"I was a little free. I sometimes talk to you like this.
・“Thank you for using it a lot. I want to give a thank you song as a gift.

In the database 19 of the navigation device 1, for example, words or phrases assumed as the content of the user's response may be stored in advance. Words may be classified as either "positive" or "negative", for example. As a positive word, for example, “yes”, “yes”, “ok”, “good”. As a negative word, for example, "No", "No", "No", "Noisy", "No". If it does not correspond to the stored phrase, it is good to treat it as unrecognizable.

Furthermore, it is preferable to store the word/phrase assumed as the response content of the user in the “dialogue” in the storage means in advance. Words may be classified as either "positive" or "negative", for example. Since there are a plurality of types of information output by the system in the "dialogue", it is better to store more words and phrases in the "dialogue" stage than in the access message output stage.

As a positive phrase, for example, “yes”, “yes”, “ok”, “is good”, “is like”, “is like”, “is like”, “knows”, and “is understood”. Negative phrases include, for example, "No", "No", "No", "Noisy", "No", "No", "No", "No", "No", "No", "No" Is good.

The navigation device 1 may select the dialog message to be output next, depending on whether the user's response to the dialog message is “positive” or “negative”.

If the user does not respond to the access message, or if the response contents cannot be recognized by voice, for example, a reminder message prompting the user to respond may be output a predetermined number of times at predetermined intervals. The prompt message prompting the user to respond may be, for example, "Hey, say something" or "I'm sad if you don't say something" when there is no response. If the voice cannot be recognized, for example, "I don't know what I said. I'll say it again." If the user does not respond to the reminder message within the predetermined time, for example, a termination message such as "see you next time" may be output to cancel the voice recognition.

(C) When the user's response to the access message is negative, the control unit 18 may output an end message including a notification that the dialogue with the user is not started, and end the voice recognition.

By not starting the dialogue when the user's response is negative, it is possible to prevent the scenario from progressing and causing the user to feel annoyed. When using a character, the user can be made to feel the modesty of the character. For example, if the user outputs a negative response "No, can I speak now?" as an access message and the user makes a negative response "No", then "I'm sorry. See you next time" It is good to output a statement.

(D) The control unit 18 may output an end message in the dialog with the user and start the event after ending the dialog with the user.

An event is started after the end of the interaction with the user, that is, the interaction with the user triggers the start of the event, for example, to motivate the user to engage in the interaction and increase his attachment to the navigation device 1. it can.

The end of the dialogue with the user may be, for example, the end of the output of the dialogue message and the cancellation of the voice recognition. The end message, which is the notification of the end of the dialogue, may inform the user that the dialogue with the character is finished, for example. For example, a combination of words of thanks and ending greetings may be output as the character's statement. For example, the following statement may be output.
・"Thank you. I'm glad. Please use it from now on. Next time again"
・"Really?I'll talk again."

The event may be, for example, new information, character information, or a combination of these information. For example, it may be image information in which the character wears a new costume. Further, for example, it may be moving image information in which the character sings a song or dances. A plurality of events may be stored in the database 19 of the navigation device 1. For the event, the event to be started may be determined according to the combination of the information output to the user and the response of the user to the information. Alternatively, the event to be started may be determined according to the time condition such as the season or the annual event and the condition of the place such as the traveling area of the vehicle.

(E) In the dialog with the user, the control unit 18 outputs a question asking for permission to start an event, outputs an end message when the user's response to the inquiry is affirmative, and starts the event after the dialogue ends. Good to do.

For example, if the predetermined event is a moving image of a character, it may take time to display all the moving images. Therefore, before the moving image is displayed, the user is asked whether or not the moving image can be displayed, and the response the user wants to display. By starting the event only when the navigation device is operated, the navigation device 1 can be made convenient for the user. For example, a question asking for permission to start an event and a user's positive response to the question may be as follows.
・Inquiry information asking for permission to start a predetermined event: "There is a special dance, can I show it now?"
・User's positive response: “Yes”, “Yes”, “Okay”, “Good”, “Thank you”

(F) In the dialogue with the user, the control unit 18 outputs a question asking for permission to start an event, and when the user's response to the question is negative, notifies the dialogue end and the predetermined event start condition. It is recommended to output the end message including the message and end the dialogue.

For example, if the event is a moving image of a character, it may take time to display all the moving images. Therefore, before the moving image is displayed, the user is asked whether or not the moving image can be displayed, and the response that the user does not want to display is displayed. In this case, instead of displaying the moving image, by notifying the display condition of the moving image, the user can watch the moving image at any time, and the system is convenient for the user. For example, the inquiry for permission to start the event, the user's negative response to the inquiry, the end message, and the event start condition may be as follows.
・Question for permission to start the event: "I have a special dance, can I show it now?"
・Negative response from the user: "No. I'm driving now."
・End message: "Okay. I will keep the image in the event log, so please access it at any time. See you later."

(G) When the event starts, the control unit 18 may display the character on the display unit 5 in a size that hinders the function of the system. For example, when displaying the image information of a character, the event ignores the original functions such as radar detector and car navigation, and displays a character with the momentum to hijack the screen, which can give a big surprise to the user. it can. Displaying with a size that hinders the function of the system may be displayed, for example, so as to cover the image already displayed on the display unit 5.

(H) The control unit 18 preferably causes the display unit 5 to display a mark indicating that the character is about to listen to the voice of the user when the voice recognition is started.

When voice recognition is started, for example, an image in which the character wears a headset or an image in which the character makes a gesture to listen to may be displayed on the display unit 5 of the navigation device 1. The user can have an impression that the character is listening to his/her voice, and can easily become familiar with the character. Further, it is easy to visually confirm that the voice recognition function is operating, which is highly convenient.

(I) When the access message output condition is satisfied, the control unit 18 may delay the output of the access message until the control condition is not satisfied when the predetermined suppression condition is satisfied.

If the user is in a situation that should be prioritized over the dialogue, for example, even if the predetermined mileage is exceeded, for example, if the acceleration condition detected from OBD is high, access message until the acceleration condition becomes low. By delaying the output of, the safety is high without impeding the ability to concentrate on driving.

The suppression conditions are, for example, that route guidance, which is the original function of the system installed in the navigation device 1, is being performed, that voice recognition is being performed, that an alarm voice is being generated, that other voice is being generated, and the character is It is preferable that the display mode is not set, the vehicle is traveling at 100 km/h or more, and so on.

[Other Embodiments]
The present invention is not limited to the above embodiment, and the following aspects can be configured.

In the above embodiment, an example in which a navigation device is used as an electronic device that constitutes the system has been described, but the present invention is not limited to this. For example, it may be a vehicle-mounted electronic device such as a radar detector or a drive recorder that has a target object notification function independent of the navigation device. Further, for example, by installing a dedicated application in a mobile terminal device such as a smartphone or a tablet, it is possible to implement the functions described in the above embodiments.

The system includes an electronic device and a server, the electronic device has a wireless communication function such as a mobile phone network such as 4G, LTE, or the Internet such as a wireless LAN. The server is connected to the Internet, and the server accesses the electronic device. It is preferable to transmit the message output instruction and output the access message based on the output instruction. For example, the server transmits the access message including the content information of the access message to the electronic device in the output instruction, and the electronic device outputs the access message in S12 when the output instruction is received in S11 of FIG. It is good to do. In particular, the server receives information from another server or another electronic device, and when the information matches a predetermined output condition for each access message, includes information on the content of the access message that matches the output condition. The output instruction may be transmitted to the electronic device.
