The guidance data GB is distributed from the distribution device 10 to the terminal device 14 together with the guidance program, for example, and stored in the storage device 34.

  The sound collection device 42 is an acoustic device (microphone) that collects ambient sounds and generates an acoustic signal Y. Specifically, the sound collection device 42 generates an acoustic signal Y representing the sound emitted by the sound emission device 26 of the sound emission system 12 (that is, a mixed sound of the guidance voice V and the acoustic component of the identification information D). To do. The sound collection device 42 of the first embodiment is used for voice recording between the terminal devices 14 or voice recording at the time of moving image shooting, and for receiving the identification information D by acoustic communication. The A / D converter that converts the acoustic signal Y generated by the sound collection device 42 from analog to digital is not shown for convenience.

  The input device 44 is an input device operated by a user for various instructions to the terminal device 14. For example, a plurality of operators operated by the user or a touch panel that detects contact by the user is preferably used as the input device 44. The output device 46 outputs the related information R of the guidance voice V. The output device 46 according to the first embodiment includes a display device 462 (for example, a liquid crystal display panel) that displays a character string represented by the related information R, and a sound emitting device 464 (for example, a speaker or an earphone) that emits the sound represented by the related information R. ).

  As illustrated in FIG. 1, the control device 32 executes the guidance program stored in the storage device 34, so that a plurality of functions (information extraction units 52, An information selection unit 54, an output control unit 56, and a related information acquisition unit 58) are realized. A configuration in which each function of the control device 32 is distributed to a plurality of devices, or a configuration in which a dedicated electronic circuit realizes a part of the function of the control device 32 may be employed.

  The information extraction unit 52 extracts the identification information D from the acoustic signal Y generated by the sound collection device 42. Specifically, the information extraction unit 52 selects an acoustic component in a frequency band including the identification information D from the acoustic signal Y using, for example, a band-pass filter, and performs demodulation processing corresponding to the modulation processing of the identification information D on the acoustic component. , The identification information D is extracted. As described above, the identification information D of the guidance voice V emitted from the sound emission device 26 is extracted by the information extraction unit 52.

  The information selection unit 54 selects related information R corresponding to the identification information D extracted by the information extraction unit 52 and the language L (hereinafter referred to as “designated language”) L designated by the terminal device 14 from the storage device 34. Specifically, the information selection unit 54 selects the related information R corresponding to the specified language L among the plurality of related information R stored for each language for the identification information D extracted by the information extraction unit 52. For example, in the example of FIG. 1, when the information extraction unit 52 extracts the identification information D2 and the designated language L is “English”, the information selection unit 54 displays the related information R indicating “Thank you.” In English. select. The information selecting unit 54 can specify the designated language L in any way, but the information selecting unit 54 can identify the designated language L by referring to the language setting of the OS (Operating System) of the terminal device 14, for example. It is also possible for the information selection unit 54 to acquire the designated language L that is arbitrarily designated by the user of the terminal device 14 by operating the input device 44.

  The output control unit 56 causes the output device 46 to output the related information R selected by the information selection unit 54. Specifically, the output control unit 56 causes the display device 462 to display a character string represented by the related information R selected by the information selection unit 54, and causes the sound emitting device 464 to emit the sound represented by the related information R. As understood from the above description, for each sound emission of the guidance voice V by the sound emission system 12, a character string expressing the utterance content of the guidance voice V in the designated language L is displayed on the display device 462 and designated. The sound that pronounces the character string of the language L is output from the sound emitting device 464.

  By the way, the guidance voice V that can be emitted by the sound emission system 12 can be added at any time. Specifically, an acoustic signal containing an acoustic component of a new guidance voice (hereinafter referred to as “new voice”) V whose utterance content is different from the existing guidance voice V and an acoustic component of identification information D of the new voice V X is stored in the storage device 34 of the sound emission system 12. When the new voice V is added, a plurality of related information R expressing the new voice V in different languages is added to the guide data GA of the distribution apparatus 10.

  At the stage where the new voice V is added, the new voice V emitted from the sound emission system 12 is picked up by the sound pickup device 42 of the terminal device 14 and the information extraction unit 52 extracts the identification information D. A situation may occur in which the related information R corresponding to the voice V is not stored in the storage device 34 of the terminal device 14. When the related information R corresponding to the identification information D extracted by the information extraction unit 52 is not stored in the storage device 34, the related information acquisition unit 58 of FIG. 1 expresses the utterance content of the new voice V in different languages. The plurality of related information R obtained from the distribution device 10 is stored in the storage device 34.

  FIG. 2 is a flowchart of an operation (hereinafter referred to as “guidance processing”) executed by the control device 32 of the terminal device 14 according to the guidance program. For example, the guidance process of FIG. 2 is started in response to an instruction from the user to the input device 44. When the user of the terminal device 14 moves within a range where the guidance voice V emitted from the sound emission device 26 of the sound emission system 12 reaches, the information extraction unit 52 uses the acoustic signal Y generated by the sound collection device 42. The identification information D of the guidance voice V is extracted (SA1).

  The information selection unit 54 determines whether or not the related information R corresponding to the identification information D extracted by the information extraction unit 52 is stored in the storage device 34 (SA2). Specifically, the information selection unit 54 determines the presence or absence of the related information R according to whether or not the identification information D extracted by the information extraction unit 52 is stored in the storage device 34. When the related information R corresponding to the identification information D is not stored in the storage device 34 (when the new voice V is added afterwards), the related information acquisition unit 58 expresses the new voice V in different languages. A plurality of related information R is acquired from the distribution device 10 and stored in the storage device 34 (SA3). Specifically, the related information acquisition unit 58 transmits a request for the related information R from the communication device 36 to the distribution device 10, and transmits a plurality of related information R distributed from the distribution device 10 in response to the request to the communication device 36. Get from. For example, the related information R corresponding to the difference between the guidance data GB of the terminal device 14 and the guidance data GA of the distribution device 10 can be distributed from the distribution device 10 to the terminal device 14. Through the above processing, the guide data GB stored in the storage device 34 of the terminal device 14 is updated to the same content as the guide data GA stored in the distribution device 10. On the other hand, when the related information R corresponding to the identification information D is stored in the storage device 34 (SA2: YES), the request (SA3) for the related information R to the distribution device 10 is not executed.

  When the above processing is executed, the information selection unit 54 selects the related information R corresponding to the identification information D extracted by the information extraction unit 52 and the designated language L of the terminal device 14 from the storage device 34 (SA4). The output control unit 56 causes the output device 46 to output the related information R selected by the information selection unit 54 (SA5). That is, in parallel with or following the sound emission of the guidance voice V by the sound emission device 26 of the sound emission system 12, the display of the character string expressing the utterance content of the guidance voice V in the designated language L and the character string are pronounced. Sound is emitted.

  For example, in a transportation facility such as a train or a bus, guidance voices that guide the user about information related to getting on and off or changing trains are reproduced as needed. If information such as translations of the pronunciation content of the guidance voice can be provided to the user along with the sound of the guidance voice, for example, a foreign user who has difficulty understanding the language of the guidance voice can understand the contents of the guidance voice. Convenient. In the first embodiment, the identification information D of the guidance voice V is extracted from the acoustic signal Y representing the sound emitted by the sound emitting device 26 that emits the guidance voice V, and the identification information D and the terminal device 14 are designated. The related information R corresponding to the language L is selected from the storage device 34 and then output from the output device 46. Therefore, it is possible to provide the related information R related to the guidance voice V in the language of the user of the terminal device 14 (designated language L).

  By the way, as a configuration for providing the user with the related information R corresponding to the identification information D of the guidance voice V and the specified language L of the terminal device 14, for example, each time the identification information D is extracted by the information extraction unit 52 A configuration in which the related information R corresponding to the information D and the specified language L is requested from the terminal device 14 to the distribution device 10 and the related information R is acquired (hereinafter referred to as “proportional”) is also assumed. In contrast, the guide data GB is not stored in the storage device 34.

  In contrast, each time the identification information D is extracted, the terminal device 14 needs to communicate with the distribution device 10 via the communication network 200. For example, since the terminal device 14 is located outside the range of the wireless communication service, the distribution device In a situation where communication with the terminal device 10 is impossible, there is a problem that the related information R corresponding to the guidance voice V cannot be provided to the user of the terminal device 14. In addition, for example, a foreign traveler may not be able to use the distribution of the related information R via the communication network 200 because the foreign traveler has not signed a use contract with the communication carrier in the visiting country. In contrast to the comparative example illustrated above, in the first embodiment, a plurality of related information R corresponding to different languages is stored in the storage device 34 of the terminal device 14 for each identification information D of the guidance voice V, The related information R corresponding to the identification information D extracted by the information extraction unit 52 and the specified language L of the terminal device 14 is selected from the storage device 34. Therefore, even when the terminal device 14 cannot communicate (for example, when it is located outside the service area of the wireless communication service), there is an advantage that related information R corresponding to the guidance voice V can be provided to the user.

  In the first embodiment, the related information acquisition unit 58 acquires the related information R that is not stored in the storage device 34 from the distribution device 10 and stores it in the storage device 34. Therefore, there is an advantage that the related information R added afterwards to the guidance data GA of the distribution device 10 can be provided to the user of the terminal device 14. In the first embodiment, in particular, when the related information R corresponding to the identification information D extracted by the information extraction unit 52 is not stored in the storage device 34 (SA2: NO), the related information acquisition unit 58 receives from the distribution device 10. Related information R is acquired. Therefore, for example, there is an advantage that the number of communication between the terminal device 14 and the distribution device 10 can be reduced as compared with a configuration in which the terminal device 14 requests the distribution device 10 for the related information R every predetermined time.

<Second Embodiment>
A second embodiment of the present invention will be described below. In the following exemplary embodiments, elements having the same functions or functions as those of the first embodiment will be referred to with the same reference numerals used in the description of the first embodiment, and detailed descriptions thereof will be omitted as appropriate.

  FIG. 3 is a configuration diagram of the guidance system 100 according to the second embodiment. Similar to the first embodiment, the distribution apparatus 10 of the second embodiment stores guide data GA including a plurality of related information R expressed in different languages for each identification information D of the guide voice V. As described above, the storage device 34 of the terminal device 14 in the first embodiment stores the guide data GB having the same contents as the guide data GA stored in the distribution device 10.

  On the other hand, the storage device 34 of the terminal device 14 in the second embodiment guides some related information R corresponding to the specified language L specified by the terminal device 14 among the guide data GA stored in the distribution device 10. Store as GB. That is, a plurality of related information R corresponding to different identification information D for the specified language L is distributed from the distribution device 10 to the terminal device 14 and then stored in the storage device 34. For example, when the designated language L is “English”, as illustrated in FIG. 3, a plurality of English related information R corresponding to different identification information D (D1, D2,...) Is stored as guide data GB in the storage device 34. Is remembered. A plurality of related information R (guidance data GB) corresponding to the designated language L is distributed from the distribution device 10 to the terminal device 14 together with, for example, the guidance program and stored in the storage device 34.

  As described above, since a plurality of related information R corresponding to the specified language L is stored in the storage device 34, the information selection unit 54 of the second embodiment corresponds to the identification information D extracted by the information extraction unit 52. The related information R to be selected is selected from the guide data GB in the storage device 34. The configuration in which the information extraction unit 52 extracts the identification information D from the acoustic signal Y or the configuration in which the output control unit 56 outputs the related information R selected by the information selection unit 54 to the output device 46 is the same as in the first embodiment. It is.

  FIG. 4 is a flowchart of guidance processing executed by the control device 32 of the terminal device 14 according to the second embodiment using a guidance program. For example, the guidance process of FIG. 4 is started in response to an instruction from the user to the input device 44. When the user of the terminal device 14 moves within the range where the guidance voice V emitted from the sound emission device 26 reaches, the information extraction unit 52 generates the sound generated by the sound collection device 42 as in the first embodiment. The identification information D of the guidance voice V is extracted from the signal Y (SB1).

  The information selection unit 54 determines whether or not the related information R corresponding to the identification information D extracted by the information extraction unit 52 is stored in the storage device 34 (SB2). When the related information R corresponding to the identification information D is not stored in the storage device 34 (SB2: NO), the related information acquisition unit 58 sends the related information R of the designated language L corresponding to the new voice V from the distribution device 10. It is acquired and stored in the storage device 34 (SB3). Specifically, the related information acquisition unit 58 transmits a request for the related information R including the notification of the specified language L from the communication device 36 to the distribution device 10, and distributes the specified language L from the distribution device 10 in response to the request. The plurality of related information R obtained is acquired from the communication device 36. For example, related information R corresponding to a difference between a set of a plurality of related information R corresponding to the specified language L in the guide data GA and the guide data GB of the terminal device 14 may be distributed from the distribution device 10 to the terminal device 14. Is possible. On the other hand, when the related information R corresponding to the identification information D is stored in the storage device 34 (SB2: YES), the request (SB3) for the related information R to the distribution device 10 is not executed.

  When the above processing is executed, the information selection unit 54 selects related information R corresponding to the identification information D extracted by the information extraction unit 52 from the storage device 34 (SB4). The output control unit 56 causes the output device 46 to output the related information R selected by the information selection unit 54 (SB5). Accordingly, in the same manner as in the first embodiment, a character string expressing the utterance content of the guidance voice V in the designated language L in parallel with or following the emission of the guidance voice V by the sound emission device 26 of the sound emission system 12. The display and the sound emission of the sound that pronounces the character string are executed.

  In the second embodiment, the same effect as in the first embodiment is realized. In the second embodiment, a plurality of related information R corresponding to the designated language L of the terminal device 14 is stored in the storage device 34 of the terminal device 14 (the related information R of languages other than the specified language L is stored in the storage device 34). Therefore, the storage capacity required for the storage device 34 is reduced compared to the first embodiment in which all the related information R in which the combination of the identification information D and the language is different is stored in the storage device 34. There is an advantage. On the other hand, according to the first embodiment in which a plurality of related information R corresponding to different languages is stored in the storage device 34, the related information R corresponding to a plurality of types of designated languages L is compared with the second embodiment. Can be provided to the user of the terminal device 14.

<Modification>
Each aspect illustrated above can be variously modified. Specific modifications are exemplified below. Two or more modes arbitrarily selected from the following examples can be appropriately combined within a range that does not contradict each other.

(1) In each of the above-described embodiments, the related information is triggered by the determination (SA2: NO, SB2: NO) that the related information R corresponding to the identification information D extracted by the information extraction unit 52 is not stored in the storage device 34. Although the acquisition unit 58 acquires the related information R from the distribution device 10, the trigger for the related information acquisition unit 58 to acquire the related information R from the distribution device 10 (that is, the trigger for updating the guidance data GB) is not limited to the above examples. . For example, each time the guidance program is activated, the related information acquisition unit 58 inquires of the distribution device 10 about whether or not the related information R is added (whether or not the guide data GA is updated). The acquisition unit 58 can also acquire the related information R from the distribution device 10. You may request | require the relevant information R from the terminal device 14 to the delivery apparatus 10 for every predetermined time during execution of a guidance program. That is, the related information acquisition unit 58 acquires the related information R from the distribution device 10 at every predetermined time during the execution of the guidance program.

  In addition, the related information acquisition unit 58 may acquire the related information R corresponding to the new voice V from the distribution device 10 when the terminal device 14 has transitioned from a state where it cannot communicate with the distribution device 10 to a state where communication is possible. Is possible. For example, when the terminal device 14 moves from the outside of the wireless communication service range to a communicable state, the related information acquisition unit 58 inquires of the distribution device 10 whether or not the related information R is added, When the information R is added, the related information R is acquired from the distribution device 10. As illustrated above, according to the configuration in which the related information acquisition unit 58 acquires the related information R from the distribution device 10 when the terminal device 14 has transitioned to a state in which the terminal device 14 can communicate with the distribution device 10, for example, the terminal device There is an advantage that the processing load of the terminal device 14 can be reduced as compared with the configuration in which the acquisition of the related information R is tried every predetermined time regardless of whether communication between the communication device 14 and the distribution device 10 is possible.

(2) In each of the above-described embodiments, the configuration in which the plurality of related information R is provided to the terminal device 14 together with the guidance program is exemplified. However, the timing for initially obtaining the guidance data GB stored in the storage device 34 is arbitrary. It is. For example, at the first activation of the guidance program, the related information acquisition unit 58 can acquire a plurality of related information R from the distribution device 10 and store it as the guide data GB in the storage device 34. Further, when the terminal device 14 first transitions to a communicable state after starting the guidance program, the related information acquisition unit 58 acquires a plurality of related information R from the distribution device 10 and stores the guidance data in the storage device 34. It is also possible to store as GB.

(3) In each of the above-described embodiments, the related information acquisition unit 58 acquires the related information R from the distribution device 10 when the related information R corresponding to the identification information D is not stored in the storage device 34 (SA2: NO). However, when it is determined that the related information R is not stored in the storage device 34, there is a possibility that the terminal device 14 cannot communicate with the distribution device 10. When the related information R is not stored in the storage device 34 and the terminal device 14 cannot communicate, the output of the related information R by the output device 46 is omitted. Assuming the above situation, a configuration in which history information indicating that the related information R corresponding to the identification information D extracted by the information extraction unit 52 could not be output is stored in the storage device 34 is also suitable. Then, at the stage where the terminal device 14 transitions to a communicable state, the related information acquisition unit 58 acquires the related information R corresponding to the identification information D indicated by the history information from the distribution device 10 and the output control unit 56 outputs it. The apparatus 46 is made to output.

(4) In the above-described embodiment, the configuration in which the acoustic signal X containing the guidance voice V is stored in advance in the storage device 24 of the sound emission system 12 is exemplified. However, the acoustic signal X is generated every time the guidance voice V is pronounced by the guide. Can also be generated sequentially. For example, the storage device 24 (or other recording medium) of the sound emission system 12 is different for each of a plurality of utterance contents scheduled to be pronounced as the guidance voice V (hereinafter referred to as “assumed guidance phrases”). Identification information D is stored. The distribution apparatus 10 stores related information R in different languages for the assumed guidance phrase of each guidance voice V. On the other hand, the guider pronounces any of a plurality of assumed guide phrases as the guide voice V. The control device 22 (or another device capable of performing voice recognition) performs voice recognition on the guidance voice V pronounced by the guide, and identifies identification information D of an assumed guidance phrase that matches or resembles the character string of the recognition result. To do. The sound emitting device 26 emits a mixed sound of the acoustic component of the identification information D specified by the control device 32 and the acoustic component of the guidance voice V. According to the above configuration, the related information R corresponding to the guidance voice V can be output at the terminal device 14 in parallel with or following the pronunciation of the guidance voice V by the guide, as in the above-described embodiments. Is possible.

(5) In each of the above-described embodiments, any one of the plurality of related information R expressed in different languages is output from the terminal device 14. However, even if the related information R of the guidance voice V is output from the terminal device 14, a disabled person such as a visually impaired person or a hearing impaired person may not be able to perceive the related information R. Considering the above circumstances, it is assumed that a configuration in which a plurality of related information R corresponding to the guidance voice V is selectively output is used for guiding various persons with disabilities.

  For example, a plurality of pieces of related information R corresponding to the type of obstacle such as visual impairment or hearing impairment are stored in the storage device 34 of the terminal device 14 for each piece of identification information D of the guidance voice V. GA). The related information R for each type of disability is created in a format that can be perceived by the user with the disability. For example, the related information R related to the visually impaired is expressed by a sound that can be perceived by a visually impaired person, and the related information R related to the hearing impaired is expressed by an image or a character string that can be perceived by the visually impaired person.

  The user of the terminal device 14 can specify the type of his / her disability by appropriately operating the input device 44. The information selection unit 54 is related information corresponding to the user's type of disability from a plurality of related information corresponding to the identification information D extracted by the information extracting unit 52 (a plurality of related information R corresponding to different types of disability). Select R. The output control unit 56 causes the output device 46 to output the related information R selected by the information selection unit 54. For example, if the user of the terminal device 14 is a visually impaired person, the related information R is emitted as sound from the sound emitting device 464, and if the user of the terminal device 14 is a hearing impaired person, the related information R is an image. Alternatively, it is displayed on the display device 462 as a character string. According to the above configuration, there is an advantage that the related information R related to the guidance voice V can be output by a method that can be perceived by a user with a disability.

  Other operations such as updating the guidance data GB are the same as those in the above-described embodiments. In the configuration for guiding the disabled person, the terminal device 14 transmits an information request specifying the identification information D extracted by the information extracting unit 52 and the type of obstacle of the user of the terminal device 14 to the distribution device 10, and the identification is performed. It is also possible to select the related information R corresponding to the information D and the type of disability from the guidance data GA and distribute it from the distribution device 10 to the terminal device 14. As understood from the above description, the related information R includes information expressed in the same language as the guidance voice V in addition to information expressed in a language different from the guidance voice V.

  The terminal device 14 according to the modification described above includes a storage device 34 that stores a plurality of related information R corresponding to different obstacles for each identification information D, and an information extraction unit that extracts the identification information D of the guidance voice V 52 and an information selection unit 54 that selects, from the storage device 34, related information R corresponding to the obstacle of the user of the terminal device 14 among the plurality of related information R corresponding to the identification information D extracted by the information extraction unit 52. And an output control unit 56 that causes the output device 46 to output the related information R selected by the information selection unit 54.

(6) The type of the related information R output from the output device 46 of the terminal device 14 can be made different depending on whether communication by the terminal device 14 is possible. For example, the storage device 34 of the terminal device 14 stores related information R such as text data with a small data amount, while the distribution device 10 stores related information R such as a still image or a moving image with a large data amount. Is done. In a state in which the terminal device 14 cannot communicate, the information selection unit 54 selects related information R (data amount: small) corresponding to the identification information D and the specified language L from the storage device 34, while the terminal device 14 is in the communication network. In a state in which communication with the distribution apparatus 10 is possible via 200, the related information acquisition unit 58 acquires related information R (data amount: large) corresponding to the identification information D and the specified language L from the distribution apparatus 10. That is, the related information R stored in the storage device 34 of the terminal device 14 and the related information R stored in the distribution device 10 are selectively output from the output device 46. Specifically, in a state in which the terminal device 14 cannot communicate, related information R such as text data with a small data amount is output from the output device 46, and in a state in which the terminal device 14 is communicable, Related information R such as a moving image is output from the output device 46.

(7) In each of the above-described embodiments, the related information R corresponding to the difference between the guide data GB stored in the storage device 34 of the terminal device 14 and the guide data GA stored in the distribution device 10 is transmitted from the distribution device 10 to the terminal device 14. Delivered. However, the range of the related information R acquired by the related information acquisition unit 58 of the terminal device 14 from the distribution device 10 is not limited to the above examples. For example, when the guide data GB stored in the storage device 34 of the terminal device 14 is different from the guide data GA of the distribution device 10, the related information acquisition unit 58 acquires all of the guide data GA from the distribution device 10 and stores it. It is also possible to store (for example, overwrite) in the device 34. The case where the guide data GA is different from the guide data GB is, for example, a case where the update of the guide data GA is not yet reflected in the guide data GB. Further, the related information acquisition unit 58 acquires a portion (a set of a plurality of related information R expressed in the specified language L) corresponding to the specified language L of the terminal device 14 in the guidance data GA from the distribution device 10 and stores it therein. It is also possible to store it in 34 (for example, overwrite).

(8) A configuration in which a specific portion of the guidance data GA is selectively distributed from the distribution device 10 to the terminal device 14 is also suitable. Specifically, as illustrated below, the related information acquisition unit 58 acquires a portion (a set of a plurality of related information R) according to the position of the terminal device 14 in the guidance data GA from the distribution device 10. Is possible.

  For example, guide data GA including a plurality of pieces of related information R corresponding to different positions for each identification information D is stored in the distribution device 10. The related information acquisition unit 58 transmits an information request including position information indicating the position of the terminal device 14 from the communication device 36 to the distribution device 10. The position information is generated using a known positioning technique such as GPS (Global Positioning System). The distribution device 10 extracts a plurality of pieces of related information corresponding to the position information included in the information request from the terminal device 14 from the guidance data GA and distributes it to the requesting terminal device 14. The related information acquisition unit 58 stores a plurality of related information R received by the communication device 36 from the distribution device 10 in the storage device 34.

  In addition, the related information acquisition unit 58 can acquire a portion (a set of a plurality of related information R) corresponding to the current time in the guidance data GA from the distribution device 10. For example, guide data GA including a plurality of pieces of related information R corresponding to different time zones for each identification information D is stored in the distribution device 10. In response to the information request from the terminal device 14, the distribution device 10 extracts a plurality of related information corresponding to the time zone including the current time from the guidance data GA and distributes it to the requesting terminal device 14. The related information acquisition unit 58 stores a plurality of related information R received by the communication device 36 from the distribution device 10 in the storage device 34.

(9) In each of the above embodiments, the identification information D is transmitted to the terminal device 14 by acoustic communication using sound as a transmission medium. However, the communication method for transmitting the identification information D to the terminal device 14 is not limited to acoustic communication. . For example, it is also possible to transmit the identification information D to the terminal device 14 by wireless communication using radio waves or electromagnetic waves such as infrared rays in parallel with or following the sound emission of the guidance voice V by the sound emission system 12. As understood from the above examples, short-range wireless communication without the communication network 200 is suitable for transmission of the identification information D, and acoustic communication using sound as a transmission medium or wireless communication using electromagnetic waves as a transmission medium is preferable. It is an illustration of near field communication. However, the transmission method of the identification information D is not limited to short-range wireless communication. For example, it is also possible to transmit the identification information D (that is, push distribution) via the communication network 200 to the terminal device 14 registered in advance as the information providing destination.
