[0005] [Patent Document 1] Japanese Patent Publication No. 2006-510004 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] This disclosure aims to provide vehicle users with appropriate information at an appropriate time. [Means for solving the problem]

[0007] The information processing device relating to the first aspect of this disclosure is: Obtaining the vehicle's current location, Calculate the current distance from the vehicle's current location to its destination, The audio output device outputs audio data generated using content information according to the current distance, A control unit configured to perform the following actions: The aforementioned content information is selected from among several candidate content information available on a website relating to an event held at the vehicle's destination, according to the current distance. [Effects of the Invention]

[0008] This disclosure will enable us to provide vehicle users with the right information at the right time. [Brief explanation of the drawing]

[0009] [Figure 1] Figure 1 shows a schematic diagram of the voice guidance system. [Figure 2] Figure 2 is a block diagram schematically showing an example of the functional configuration of an in-vehicle device. [Figure 3] Figure 3 shows an example of the table structure of keyword information held in a keyword information database. [Figure 4]Figure 4 is a flowchart of the generation process performed by the control unit of the in-vehicle device. [Figure 5] Figure 5 is a flowchart of the output processing performed by the control unit of the in-vehicle device. [Modes for carrying out the invention]

[0010] An event may be held at the vehicle's destination. In this scenario, it is assumed that the vehicle user receives voice guidance about the event at the destination while the vehicle is in motion. In this case, if the vehicle is far from the destination, the time it takes to reach the destination will be longer than if the vehicle is close. In other words, the time it takes to reach the destination will differ depending on the vehicle's location. Therefore, it is assumed that the information the vehicle user needs will differ depending on the vehicle's location.

[0011] The control unit of the information processing device according to this disclosure acquires the vehicle's current location. The control unit of the information processing device according to this disclosure calculates the current distance from the vehicle's current location to its destination. The control unit then outputs audio data generated using content information to an audio output device according to the current distance. Here, the content information is selected from several candidate content information available on a website related to an event held at the vehicle's destination, according to the current distance.

[0012] As explained above, the information processing device related to this disclosure outputs audio data corresponding to the current distance. This makes it possible to provide information that is assumed to be needed by the vehicle user according to the vehicle's location. As a result, it becomes possible to provide the vehicle user with the appropriate information at the appropriate time.

[0013] Hereinafter, specific embodiments of the present disclosure will be described based on the drawings. The hardware configurations, module configurations, functional configurations, etc. described in each embodiment are not intended to limit the technical scope of the disclosure only to them unless otherwise specified.

[0014] <Embodiment> (Overview of the System) The voice guidance system 1 in the present embodiment will be described based on FIG. 1. FIG. 1 is a diagram showing the schematic configuration of the voice guidance system 1. The voice guidance system 1 includes an in-vehicle device 100 and a web server 200. In the voice guidance system 1, the in-vehicle device 100 and the web server 200 are interconnected by a network N1. The network N1 may adopt, for example, a WAN (Wide Area Network), which is a global public communication network such as the Internet, or a telephone communication network such as a mobile phone.

[0015] (Web Server) The web server 200 is a server device that provides a website related to an event. The web server 200 provides the website by transmitting data for displaying the website related to the event via the network N1.

[0016] (In-Vehicle Device) The in-vehicle device 100 is a device mounted on the vehicle 10. The in-vehicle device 100 is a device that provides information to the user of the vehicle 10. The in-vehicle device 100 is, for example, a car navigation system mounted on the vehicle 10.

[0017] Here, an event may be held at the destination of the vehicle 10 (the destination of the user of the vehicle 10). At this time, while the vehicle 10 is traveling, the in-vehicle device 100 provides voice guidance to the user of the vehicle 10 about the event held at the destination. In this case, when the vehicle 10 is at a position far from the destination, the time required to reach the destination is longer than when the vehicle 10 is at a position close to the destination. That is, the time required to reach the destination varies depending on the position of the vehicle 10.

[0018] At this time, assume that information about the details of an event (hereinafter sometimes simply referred to as "event") held at the destination is provided as voice guidance when the vehicle is at a position far from the destination. Then, since the time required for the vehicle 10 to reach the destination is longer compared to when the vehicle 10 is at a position close to the destination, it is assumed that the user will forget the details of the event by the time the vehicle 10 reaches the destination.

[0019] On the other hand, assume that information about the outline of the event is provided as voice guidance when the vehicle 10 is at a position far from the destination, and more detailed information about the event is provided as voice guidance as the vehicle 10 gets closer to the destination. Then, as the vehicle 10 approaches the destination, more detailed information about the event is provided, so the user of the vehicle 10 can enhance the sense of expectation for the event. Therefore, the in-vehicle device 100 provides voice guidance about the information on the outline of the event and the information on the details of the event according to the distance from the current position of the vehicle 10 to the destination.

[0020] Here, information about the event outline refers to, for example, information about the event's schedule. The event schedule includes, for example, information about the event's location (destination) or the event's start time. Information about the event details is more detailed than the information about the event outline. Information about the event details includes, for example, the latest information, the event's performers, or the performers' performance times. Information about the event details may also include information about companies exhibiting at the event or information about the event's sponsors. Details on how the in-vehicle device 100 provides voice guidance for the event outline and event details will be described later.

[0021] The in-vehicle device 100 is comprised of a computer having a processor 110, a main memory unit 120, an auxiliary memory unit 130, a communication interface (communication I / F) 140, and a speaker 150. The processor 110 is, for example, a CPU (Central Processing Unit) or a DSP (Digital Signal Processor). The main memory unit 120 is, for example, RAM (Random Access Memory). The auxiliary memory unit 130 is, for example, ROM (Read Only Memory). Alternatively, the auxiliary memory unit 130 may be, for example, an HDD (Hard Disk Drive), or a disk recording medium such as a CD-ROM, DVD disc, or Blu-ray disc. The auxiliary memory unit 130 may also be removable media (portable storage medium). Here, examples of removable media include, for example, a USB memory stick or an SD card. The communication I / F 140 is, for example, a LAN (Local Area Network) interface board or a wireless communication circuit for wireless communication. Speaker 150 is a speaker for outputting sound inside the vehicle 10.

[0022] In the in-vehicle device 100, the auxiliary storage unit 130 stores the operating system (OS), various programs, and various information tables. Furthermore, in the in-vehicle device 100, the processor 110 loads the programs stored in the auxiliary storage unit 130 into the main memory unit 120 and executes them, thereby realizing various functions as described later. However, some or all of the functions of the in-vehicle device 100 may be realized by hardware circuits such as ASICs or FPGAs. Note that the in-vehicle device 100 does not necessarily have to be realized by a single physical configuration, but may be composed of multiple computers cooperating with each other. Similarly, the web server 200 is also configured to include a computer, in the same way as the in-vehicle device 100.

[0023] (Functional Configuration) Next, the functional configuration of the in-vehicle device 100 that constitutes the voice guidance system 1 will be explained based on Figures 2 and 3. Figure 2 is a block diagram that schematically shows an example of the functional configuration of the in-vehicle device 100. The in-vehicle device 100 consists of a control unit 101, a communication unit 102, a position acquisition unit 103, an input / output unit 104, a voice output unit 105, and a keyword information database 106 (keyword information DB 106).

[0024] The control unit 101 has the function of performing calculation processing for controlling the in-vehicle device 100. The control unit 101 can be implemented by the processor 110 in the in-vehicle device 100. The communication unit 102 has the function of connecting the in-vehicle device 100 to the network N1. The communication unit 102 can be implemented by the communication interface 140 in the in-vehicle device 100.

[0025] The position acquisition unit 103 has the function of acquiring the current position of the vehicle 10 (onboard device 100). The position acquisition unit 103 can be implemented by an interface for acquiring the current position of the vehicle 10 from a GPS sensor in the vehicle 10. Alternatively, the position acquisition unit 103 may be implemented by a GPS sensor built into the onboard device 100. The control unit 101 acquires the current position of the vehicle 10 in real time via the position acquisition unit 103. This enables the control unit 101 to accurately determine the current position of the vehicle 10.

[0026] The input / output unit 104 has the function of allowing the user of the vehicle 10 to input various information into the in-vehicle device 100. The input / output unit 104 also has the function of displaying various information to the user of the vehicle 10. The input / output unit 104 can be implemented by a touch panel display in the in-vehicle device 100.

[0027] The control unit 101 obtains the destination of the vehicle 10 via the input / output unit 104. The control unit 101 accesses a website related to an event held at the vehicle 10's destination by accessing the web server 200 via the communication unit 102. At this time, the control unit 101 may access the web server 200 by searching for an event held at the destination.

[0028] The control unit 101 searches for predetermined keywords on a website related to the event. Here, the predetermined keywords are associated with the distance from the vehicle 10 to the destination. Information indicating the predetermined keywords is pre-stored as keyword information in the keyword information DB 106.

[0029] The keyword information DB106 has the function of storing keyword information. The keyword information DB106 contains information about predetermined keywords corresponding to the distance from the vehicle 10 to the destination. The keyword information DB106 can be implemented by the auxiliary storage unit 130 in the in-vehicle device 100. Figure 3 is a diagram showing an example of the table configuration of keyword information stored in the keyword information DB106. As shown in Figure 3, the keyword information is based on the distance field It includes a keyword field and a priority field.

[0030] The distance field stores information indicating the distance to the destination. The distance field may store multiple distance values. The keyword field stores information indicating keywords (predetermined keywords) corresponding to the distances stored in the distance field. The keyword field may store multiple keywords corresponding to the distances indicated in the corresponding distance field. The priority field stores the priority for the corresponding keyword field.

[0031] The control unit 101 retrieves a predetermined keyword from the keyword information stored in the keyword information DB 106 and searches for the predetermined keyword on the event-related website. At this time, the control unit 101 searches for the predetermined keyword in order of priority until the predetermined keyword is detected as a search result on the event-related website. Then, the control unit 101 selects (extracts) the information (content information) associated with the predetermined keyword. At this time, the control unit 101 searches for the predetermined keyword according to each distance and extracts content information according to each distance. In this case, if the predetermined keyword is not detected as a search result, the extraction of content information at the corresponding distance may be omitted.

[0032] Specifically, the control unit 101 searches the source code of the website obtained from the web server 200 for linked pages tagged with predetermined keywords. Then, the control unit 101 selects the information contained in the linked pages tagged with the predetermined keywords and obtains it as content information.

[0033] In this embodiment, the control unit 101 searches for keywords corresponding to the first distance and keywords corresponding to the second distance, and extracts content information corresponding to the first distance and content information corresponding to the second distance. Here, the second distance is shorter than the first distance. Therefore, in order to extract content information corresponding to the first distance, the control unit 101 searches for link pages that contain keywords about the outline of the event. In this case, the predetermined keywords are, for example, "event overview". The control unit 101 also searches for link pages that contain keywords about the details of the event in order to extract content information corresponding to the second distance. In this case, the predetermined keywords are, for example, "latest information". In this way, the control unit 101 selects content information from among multiple candidates of content information present on the website according to the current distance.

[0034] The control unit 101 generates first audio data from the extracted first content information. The control unit 101 also generates second audio data from the extracted second content information. Specifically, the control unit 101 generates audio data for reading aloud the text contained in the content information (first content information and second content information).

[0035] In this case, there may be content information whose information volume exceeds a threshold. The information volume of content information exceeds the threshold when, for example, the amount of text contained in the content information is greater than or equal to the threshold. In this case, if audio data is output from content information whose information volume exceeds the threshold, the audio guidance will become long due to the large amount of information. This may cause confusion for the user of vehicle 10 who receives the long audio guidance. Also, the long audio guidance may diminish the user's interest in the audio guidance. Therefore, if the information volume of the content information exceeds the threshold, the control unit 101 performs a summarization process on the content information and generates audio data. Here, the control unit 101 performs the content information summarization process using, for example, a summarization AI.

[0036] The audio output unit 105 has the function of outputting various sounds to the user of the vehicle 10. The audio output unit 105 can be realized by the speaker 150 in the in-vehicle device 100. The control unit 101 causes the generated audio data to be output to the audio output unit 105. Specifically, the control unit 101 converts the audio data into an audio output signal and outputs it to the audio output unit 105. This enables voice guidance within the vehicle 10.

[0037] Here, the control unit 101 outputs audio data at a predetermined timing. The control unit 101 outputs the first audio data at a predetermined timing when the current distance of the vehicle 10 and the distance to the destination (current distance) are less than the first distance, the current distance exceeds the second distance, and predetermined conditions are met. In other words, the control unit 101 permits the output of the first audio data when the current distance is less than the first distance and exceeds the second distance and predetermined conditions are met. Here, the control unit 101 may also permit the output of the first audio data when the current distance is less than or equal to the first distance and exceeds the second distance and predetermined conditions are met.

[0038] Furthermore, the control unit 101 outputs the second voice data at a predetermined timing when the current position of the vehicle 10 and the distance to the destination (current distance) are less than the second distance and predetermined conditions are met. In other words, the control unit 101 permits the output of the second voice data when the current distance is less than the second distance and predetermined conditions are met. Here, the control unit 101 may also permit the output of the second voice data when the current distance is less than or equal to the second distance and predetermined conditions are met.

[0039] The predetermined condition is that no point is included within a predetermined range from the vehicle 10's current position where voice guidance (route guidance) regarding the route to the destination is to be provided. In this case, the predetermined range is the range up to a predetermined distance before the point where route guidance is to be provided. The control unit 101 refers to information indicating the vehicle 10's planned route and the timing of route guidance, and determines whether or not a point is included within a predetermined range from the vehicle 10's current position where voice guidance (route guidance) regarding the route to the destination is to be provided. This makes it possible to suppress the output of the first voice data or the second voice data at a time when route guidance is needed.

[0040] Furthermore, the predetermined range may be a predetermined distance beyond the point where route guidance is provided. This prevents the output of the first or second voice data immediately after route guidance is provided. This prevents the output of the first or second voice data while the user of vehicle 10 is concentrating on driving in order to follow the route guidance.

[0041] Furthermore, the predetermined condition may be that a curved road is not included within a predetermined range from the current position of the vehicle 10. This prevents the output of the first or second audio data at a time when the user of the vehicle 10 is concentrating on driving. In this case, the predetermined range is the range up to a predetermined distance before the start of the curved road. This prevents the output of the first or second audio data at a time when the user of the vehicle 10 is concentrating on driving in order to navigate the curve. Alternatively, the predetermined range may be the range up to a predetermined distance beyond the end of the curved road. This allows the output of the first or second audio data at a time when the user of the vehicle 10 has finished driving on the curved road and is driving on a straight road, thus easing their tension.

[0042] (Generation process) In the voice guidance system 1, the generation process performed by the control unit 101 in the in-vehicle device 100 will be explained with reference to Figure 4. Figure 4 is a flowchart of the generation process performed by the control unit 101. The generation process involves generating voice data (first tone) according to the current distance. This is a process for generating voice data or second voice data.

[0043] In the generation process, first, in S101, content information (first content information or second content information) corresponding to the current distance is obtained (selected) from the website. Next, in S102, it is determined whether the amount of information in the content information exceeds a threshold. If the determination in S102 is positive, summarization processing is performed on the content information in S103. Then, in S104, audio data (first audio data or second audio data) is generated using the content information that has undergone summarization processing. Finally, the generation process is completed.

[0044] Furthermore, if a negative result is obtained in S102, the amount of information is deemed suitable, so the summarization process is omitted, and the process in S104 is executed. Then, the generation process is terminated.

[0045] In this embodiment, in the process of S102, an affirmative judgment is made if the amount of information exceeds the threshold. Also, in the process of S102, a negative judgment is made if the amount of information is less than the threshold. In this case, the amount of information may be equal to the threshold. In this case, either an affirmative or negative judgment may be made.

[0046] (Output processing) Next, the output processing performed by the control unit 101 in the in-vehicle device 100 in the voice guidance system 1 will be explained with reference to Figure 5. Figure 5 is a flowchart of the output processing performed by the control unit 101. The output processing is the process of outputting the first voice data and the second voice data to the voice output unit 105. The output processing starts when the user enters a destination into the input / output unit 104.

[0047] In the output processing, first, in S201, the acquisition of the vehicle 10's current position begins. This allows for real-time acquisition of the vehicle 10's position. Next, in S202, the current distance is calculated. This allows for real-time acquisition of the current distance.

[0048] Next, in S203, it is determined whether the current distance is less than the first distance. If the determination in S203 is negative, it is not time to provide voice guidance to the user of vehicle 10 according to the first voice data, so the process in S203 is executed again. In other words, the process in S203 is executed repeatedly until the current distance is less than the first distance.

[0049] If a positive determination is made in S203, the current distance is less than the first distance. Also, at this time, since vehicle 10 is traveling toward the destination, the current distance exceeds the second distance. Therefore, in S204, the process of generating the first voice data is executed. Next, in S205, it is determined whether or not predetermined conditions are met. If a negative determination is made in S205, the predetermined conditions are not met, so the process in S205 is executed again. In other words, the process in S205 is executed repeatedly until the predetermined conditions are met. If a positive determination is made in S205, the current distance is less than the first distance and exceeds the second distance, and the predetermined conditions are met. In other words, if a positive determination is made in S205, it is a suitable timing to provide voice guidance according to the first voice data. Therefore, in S206, the output of the first voice data is performed via the voice output unit 105.

[0050] Next, in S207, it is determined whether the current distance is less than the second distance. If the determination in S207 is negative, it is not time to provide voice guidance to the user of vehicle 10 according to the second voice data, so the process in S204 is executed again. In other words, the process in S207 is executed repeatedly until the current distance is within the second distance.

[0051] If a positive result is obtained in S207, the process for generating the second voice data is executed in S208. Next, in S209, it is determined whether or not predetermined conditions are met. If a negative result is obtained in S209, the predetermined conditions are not met, and the process in S209 is executed again. In other words, the process in S209 is executed repeatedly until the predetermined conditions are met. If a positive result is obtained in S209, the current distance is less than the second distance, and the predetermined conditions are met. In other words, if a positive result is obtained in S209, it is a suitable time to provide voice guidance according to the second voice data. Therefore, in S210, the output of the second voice data is performed via the voice output unit 105. Then, the output process is terminated.

[0052] As explained above, the voice guidance system 1 outputs first and second voice data according to the current distance. This makes it possible to provide information that is assumed to be needed by the user of vehicle 10 according to the vehicle's location. As a result, it becomes possible to provide the user of vehicle 10 with appropriate information at an appropriate time.

[0053] (Variation 1) In this embodiment, the in-vehicle device 100 outputs two types of audio data: first audio data and second audio data. However, the in-vehicle device 100 may output two or more types of audio data. In this case, the in-vehicle device 100 acquires three or more pieces of content information according to keywords predetermined according to distance and generates audio data. At this time, the keywords are set so that the content information becomes more detailed about the event as the distance to the destination approaches. As a result, the vehicle 10 can provide more detailed audio guidance about the event as it approaches its destination. Even in this way, it is possible to provide the user of the vehicle 10 with appropriate information at an appropriate time.

[0054] (Modification 2) The in-vehicle device 100 may obtain content information from a website that corresponds to a predetermined area along the planned route of the vehicle 10. In this case, the in-vehicle device 100 determines whether or not the vehicle 10 is within the predetermined area. If the vehicle 10 is within the predetermined area, the in-vehicle device 100 may output audio data generated from the corresponding content information for the predetermined area.

[0055] Here, the content information corresponding to the designated area is an area that includes locations related to the event in addition to the destination. As a result, when vehicle 10 is within the designated area, corresponding audio data is output, allowing the user of vehicle 10 to receive audio guidance corresponding to locations related to the event. The content information corresponding to the designated area is, for example, information about the factory of a sponsor company of the event. In this case, the designated area is the area that includes the factory of a sponsor company of the event. Even in this way, it is possible to provide the user of vehicle 10 with appropriate information at an appropriate time.

[0056] (Variation 3) In this embodiment, the generation process for the first audio data is performed when the current distance falls below the first distance. Also in this embodiment, the generation process for the second audio data is performed when the current distance falls below the second distance. However, the generation processes for the first and second audio data do not necessarily have to be performed at these timings. The generation processes for the first and second audio data may be performed, for example, when the destination of the vehicle 10 is input to the in-vehicle device 100. Even in this case, the user of the vehicle 10 can still be informed. This makes it possible to provide the right information at the right time.

[0057] <Other Embodiments> The embodiments described above are merely examples, and this disclosure may be modified as appropriate without departing from its essence. Furthermore, the processes and means described in this disclosure may be freely combined and implemented as long as no technical inconsistencies arise.

[0058] Furthermore, a process described as being performed by a single device may be divided and executed by multiple devices. Conversely, a process described as being performed by different devices may be executed by a single device. In a computer system, the hardware configuration (server configuration) by which each function is implemented can be flexibly changed.

[0059] The present disclosure can also be realized by supplying a computer program implementing the functions described in the embodiments above to a computer, and having one or more processors in the computer read and execute the program. Such a computer program may be provided to the computer by a non-temporary computer-readable storage medium that can be connected to the computer's system bus, or it may be provided to the computer via a network. The non-temporary computer-readable storage medium includes any type of disk, such as magnetic disks (floppy disks or hard disk drives (HDDs), etc.), optical disks (CD-ROMs, DVDs, or Blu-ray discs, etc.), read-only memory (ROM), random access memory (RAM), EPROM, EEPROM, magnetic cards, flash memory, or optical cards, and any other type of medium suitable for storing electronic instructions.
