  Each electrode P is connected to a transceiver 1 at the same location by a conductive wire, and each transceiver 1 is connected to the same server 2 via a local area network. The transceiver 1 is placed, for example, under the floor. For example, the server 2 is installed at a location away from each exhibit E.

  A plurality of terminals 3 are prepared in the art museum, and the terminals 3 are handed over to each user U visiting the art museum. The user U wears the terminal 3 and listens to the audio content reproduced by the terminal 3 through the headphones 4. It is like that.

  The transceiver 1 includes a memory 11 that stores an address indicating the transceiver 1, a control unit 12 that performs reading of the address and transmission control of such information, an oscillation circuit 13 that operates during information transmission, and transmitted information Is provided. The oscillation circuit 13 applies a voltage based on information to be transmitted to the electrode P. The detection circuit 14 detects information by the voltage applied to the electrode P. Hereinafter, an address indicating the transceiver 1 is simply referred to as an “address”.

  FIG. 3 is a configuration diagram of the server 2.

  The server 2 includes a content database 21 in which audio contents and the like about exhibits are stored, a terminal information database 22 in which information about each terminal 3 is stored, and a history database 23 in which history of content transmission is stored And a control unit 24 that reads and writes these databases and transmits and receives information. In the following description and drawings, the database is abbreviated as “DB”.

  The content DB 21 stores a content ID (such as GAE in the figure) indicating the content, version information (such as 1.0 in the figure), and “content information” including the content. Each piece of content information is associated with an address indicating the transceiver 1 where the content is to be reproduced. Each piece of content information is associated with attribute identification information indicating the attribute of the user U suitable for the content. However, the content information associated with the address indicating the transceiver 1 connected to the electrode P of the fence 100 is simply an “alarm instruction” indicating that an alarm should be issued. In the following description and drawings, the identification information is abbreviated as “ID”. For example, the attribute ID can distinguish between an adult and a child, and can distinguish between a user who can understand Japanese and a user who can understand only English. In addition, you may enable it to distinguish an age, an age group, etc.

  The terminal information DB 22 stores the content ID and version information of the content stored in the terminal 3 in association with the terminal ID that uniquely indicates each terminal 3.

  The terminal ID storage unit 312 stores the terminal ID of the terminal 3. The attribute ID storage unit 313 stores the attribute ID of the user U who uses the terminal 3.

(Content playback method according to this embodiment)
FIG. 5 is a sequence diagram of the content reproduction method according to the present embodiment.

  When the user U visits the museum, one of the prepared terminals 3 is selected at random, and an attribute ID indicating the attribute of the visited user U is written in the attribute ID storage unit 313 of the terminal 3 ( In step S <b> 1, the terminal 3 and the headphones 4 are delivered to the user U.

  The user U wears the headphones 4 and connects the cord to the terminal 3, and the terminal 3 is put in a pocket or the like.

  Each transceiver 1 always performs polling, that is, the control unit 12 oscillates the oscillation circuit 33 based on information indicating polling (referred to as polling information). As a result, a voltage having a waveform corresponding to the polling information is applied to the electrode P. Therefore, when the user U stands on the electrode P, the electrode P is capacitively coupled to the user U, and an electric field is generated between the user U and the ground. A part of the electric field passes through the electrode 34 of the terminal 3 so that a voltage having the same waveform is applied to the electrode 34. The detection circuit 35 of the terminal 3 reproduces the polling information based on the waveform of the voltage applied to the electrode 34 and gives it to the control unit 32. If it is known polling information, the control unit 32 transmits the terminal ID and the attribute ID to the transceiver 1 (step S11). Here, the control unit 32 of the terminal 3 reads the terminal ID from the terminal ID storage unit 312 and the attribute ID from the attribute ID storage unit 313, and oscillates the oscillation circuit 33 based on the terminal ID and the attribute ID. Thereby, a voltage having a waveform corresponding to the terminal ID and the attribute ID is applied to the electrode 34. The electrode 34 is capacitively coupled to the user U, such as in a pocket, and an electric field is generated between the user U and the ground. A part of the electric field passes through the electrode P, so that a voltage having the same waveform is applied to the electrode P. The detection circuit 14 of the transceiver 1 reproduces the terminal ID and the attribute ID based on the waveform of the voltage applied to the electrode P, and gives it to the control unit 12.

  The transceiver 1 transmits the transmitted terminal ID, attribute ID, and address to the server 2 (step S13). Here, the control unit 12 reads the address from the memory 11 and transmits it to the server 2 together with the terminal ID and the attribute ID given from the detection circuit 14.

  In the server 2, the control unit 24 reads the content information associated with the address from the content DB 21, and determines whether this is an “alarm command” (step S21).

  When it determines with NO, the control part 24 determines whether content ID and version information in the read content information are matched with transmitted terminal ID in terminal information DB22 (step S23). ). When it is determined NO, the control unit 24 transmits the transmitted terminal ID and content information (content / content ID / version information) to the original transceiver 1 with the transmitted address as the destination, that is, the original transceiver 1 (step S1). S25).

  Further, the control unit 24 causes the history DB 23 to store history information indicating an event that the terminal ID and the content information are transmitted. Here, the control unit 24 causes the history DB 23 to store history information including the transmitted terminal ID, the content ID in the transmitted content information, the version information, and the time stamp. By storing the history information in this way, an event occurring in the server 2 can be known later.

  Moreover, the control part 24 updates terminal information DB22 (step S27). Here, if there is a content ID in the read content information in the terminal information DB 22, the control unit 24 deletes the content ID and version information from the terminal information DB 22. After that, or even if not deleted, the control unit 24 associates the content ID and the version information in the read content information with the transmitted terminal ID in the terminal information DB 22. That is, the control unit 24 updates the version information.

  On the other hand, the transceiver 1 transmits the transmitted terminal ID and content information to the terminal 3 corresponding to the terminal ID, that is, the original terminal 3 (step S29). The transmission method is the same as in the case of polling, and an electric field is used.

  The terminal 3 stores the transmitted content information in the content cache DB 311 and reproduces the content (step S31). Here, the control unit 32 determines whether or not the given terminal ID and the terminal ID stored in the terminal ID storage unit 312 are the same, and performs the following only when they are the same. That is, if there is a content ID in the given content information in the content cache DB 311, the control unit 32 deletes the content information including the content ID from the content cache DB 311. Then, the control unit 32 converts the content in the content information into an analog signal while storing the given content information in the content cache DB 311, and transmits the analog signal to the headphones 4 to reproduce the content.

  Thus, for example, when the user U is “adult and Japanese” and is in “a place of a certain famous painting (exhibit)”, the content corresponding to the attribute and the place, that is, the exhibit is displayed. The detailed Japanese audio content is reproduced, and the user U can enjoy the benefits. That is, the contents for each place and each user can be reproduced on the terminal 3 owned by the user.

  Further, since the terminal 3 determines the identity between the given terminal ID and the stored terminal ID, the reproduction of such content is performed by a plurality of users standing at the same place, that is, standing on the same electrode P. It can also be made possible by other terminals.

  When it is determined YES in step S23, the control unit 24 transmits the transmitted terminal ID, the content ID in the content information, and the reproduction command to the original transceiver 1 with the transmitted address as the destination ( Step S41).

  Further, the control unit 24 causes the history DB 23 to store history information indicating an event that the terminal ID, the content ID, and the reproduction command are transmitted. Here, the control unit 24 stores history information including the transmitted terminal ID, content ID, and time stamp in the history DB 23. By not including version information in the history information, it is possible to know later that a playback command has been transmitted.

  The transceiver 1 transmits the transmitted terminal ID, content ID, and playback command to the original terminal 3 corresponding to the terminal ID (step S43). The transmission method is the same as in the case of polling and the like, and an electric field is used.

  Similar to step S31, the terminal 3 performs the following only when the given terminal ID is the same as the stored terminal ID. That is, if a reproduction command is transmitted, the content in the content information including the transmitted content ID is read and reproduced (step S51). Here, the control unit 32 reads the content in the content information including the transmitted content ID from the content cache DB 311, converts the content into an analog signal, and transmits the analog signal to the headphones 4 to reproduce the content.

  In this way, not the content but the amount of information that is normally smaller than the amount of information transmitted is transmitted to the terminal 3, and the stored content is reproduced by the terminal 3 by the reproduction command, so that the communication band of the transceiver 1 can be saved. . As a result, it is possible to prevent the following inconveniences, that is, the lack of the communication band of the transceiver 1 and the interruption of the sound of the content or the inability to reproduce it.

  If it is determined YES in step S21, the control unit 24 transmits the transmitted terminal ID and alarm command to the original transceiver 1 with the transmitted address as the destination (step S61).

  Moreover, the control part 24 memorize | stores the log | history information which shows the event that terminal ID and the warning command were transmitted in log | history DB23. Here, the control unit 24 stores history information including the transmitted terminal ID and a time stamp in the history DB 23. By not including the content ID and version information in the history information, it is possible to know later that an alarm command has been transmitted, that is, that the user U has touched the fence 100. Moreover, the time when the user U touched the fence 100 can be known later by the time stamp. Further, if the terminal ID and the name of the user U are recorded in correspondence at the entrance, the name of the user U who touched the fence 100 can be known later.

  The transceiver 1 transmits the transmitted terminal ID and warning command to the original terminal 3 corresponding to the terminal ID (step S63). The transmission method is the same as in the case of polling and the like, and an electric field is used.

  Similar to step S31 and the like, the control unit 32 performs the following only when the given terminal ID is the same as the stored terminal ID. That is, if an alarm command is transmitted, for example, a beep sound is reproduced (step S71). Here, the control unit 32 generates an analog signal of a beep sound and transmits it to the headphones 4 to reproduce the beep sound.

  Thus, by reproducing the beep sound, it is possible to prevent damage to important exhibits.

  The control unit 32 preferably gives priority to reproduction of a beep sound over reproduction of content. For example, when an alarm command is transmitted during reading and reproduction of content, the control unit 32 stops reproduction and reproduces a beep sound. In addition, an alarm command can be transmitted even during content transmission by time division. When the alarm command is transmitted while content is being received and reproduced, the control unit 32 stops reproduction and reproduces a beep sound. In place of the beep sound, a verbal warning sound may be reproduced.

  As described above, according to the present embodiment, the oscillation circuit of the terminal worn by the user who visited the transceiver place applies a voltage having a waveform corresponding to the terminal ID and the attribute ID to the terminal electrode. When a voltage based on the terminal ID and the user's attribute ID is applied to the terminal electrode and an electric field is generated between the user and the ground, the transceiver detection circuit is capacitively coupled to the electrode at the same location. Therefore, the terminal ID and the attribute ID are detected based on the voltage of the electrode at the same place through which a part of the electric field passes, and the transceiver control unit sends the terminal ID, the attribute ID, and the address of the transceiver to the server. The server control unit reads out the content information associated with the address and attribute ID from the content database, and in the terminal information database, stores the content information in the content information. It is determined whether or not the content ID is associated with the terminal ID. If it is determined that the content ID is not associated with the content ID, the terminal ID and the content information are transmitted with the address as the destination. Is transmitted to the terminal ID, the content ID in the content information and the playback command are transmitted with the address as the destination, and the transceiver oscillation circuit is transmitted. A voltage based on what is transmitted by the transceiver is applied to the electrode at the same location, resulting in an electric field between the user and the ground. When the user is capacitively coupled to the electrode of the terminal, the transmitted voltage is detected by the voltage of the electrode through which part of the electric field passes, and the terminal is controlled However, when the terminal ID and the content information are detected by the detection circuit and the terminal ID is stored in the terminal ID storage unit, the content information is stored in the content cache database and the content in the content information is reproduced. When the terminal ID, the content ID, and the playback command are detected by the detection circuit and the terminal ID is stored in the terminal ID storage unit, the content in the content information including the content ID is read from the content cache database and played back By doing so, content for each location and for each user can be played back on the terminal of the user, and it can be played on the terminals of a plurality of users in the same location, and the communication bandwidth of the transceiver provided in each location can be saved. .

  Further, the control unit of the server reads the content information associated with the address and the attribute ID from the content database, and the content ID and the version information in the content information are associated with the terminal ID in the terminal information database. If it is determined that the terminal ID and the content information are not associated with each other, the terminal ID and the content information are transmitted with the address as the destination, and the content ID and the version information are associated with the terminal ID in the terminal information database. If it is determined that the content is associated, the content managed by the version information can be reproduced on the terminal of the user by transmitting the terminal ID, the content ID in the content information, and the reproduction command as the address. And even if it ’s multiple users ’devices in the same place, An ability moreover can save communication band transceiver provided in each location.

  The server also includes a history database that stores history information including a terminal ID, a content ID, and a time stamp transmitted to the transceiver, and the control unit of the server includes the terminal ID, the content ID, and the time stamp transmitted to the transceiver. By storing the history information in the history database, such an event can be known later.

  Further, the content database includes an alarm command that is content information associated with the same address, and when the control unit of the server reads the alarm command, the terminal ID and the alarm command are transmitted with the address as the destination, When the terminal ID and the alarm command are detected and the terminal ID is stored in the terminal ID storage unit, the terminal control unit operates to give an alarm to the user of the terminal, for example, It is possible to prevent damage to the exhibits.
