It is a block diagram which shows the structure of another information acquisition system in one Embodiment. It is a side view which shows another electrode structure for the structure of the information acquisition system in one Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing the configuration of the information acquisition system in the present embodiment. The information acquisition system shown in the figure includes a user terminal 2 held by a user 1, a poster 3, a plurality of electrodes 41 and 42, a switch 5, a transceiver 6, and a host 7.

  The user terminal 2 has a human body communication function for transmitting and receiving signals using the user 1 as a communication path, and a display function for displaying the received detailed information.

  On the front of the poster 3, a plurality of simple information such as product names are presented. On the back side of the poster 3, a plurality of electrodes 41 and 42 are arranged in correspondence with simple information presented on the front surface of the poster 3.

  The switch 5 selects one of the electrodes 41 and 42 and connects it to the transceiver 6.

  The transmitter / receiver 6 transmits / receives data to / from the user terminal 2 via the electrodes 41 and 42 connected by the switch 5 and the user 1. When the user 1 approaches the electrodes 41 and 42, a communication path between the user terminal 2 and the transceiver 6 is established. The transmitter / receiver 6 identifies the electrodes 41 and 42 that the user 1 has approached, reads detailed information corresponding to the electrodes 41 and 42 from the host 7, and transmits the detailed information to the user terminal 2. The electrodes 41 and 42 are arranged corresponding to the information presented in the poster 3, and detailed information is stored in the host 7 corresponding to the electrodes 41 and 42. Thereby, the transmitter / receiver 6 can read out detailed information corresponding to the information presented on the poster 3 from the host 7 and transmit it.

  Next, the process in which the user terminal 2 receives detailed information will be described. FIG. 2 is a sequence diagram illustrating a flow of processing in which the user terminal 2 obtains detailed information when the user touches a poster.

  First, when the user 1 contacts the poster 3 on which the product or information for which detailed information is desired to be obtained is touched, the electrode 41 arranged in correspondence with the product or information described on the poster 3 and the user 1 come close to each other, and the user terminal 2 and the transceiver 6 are established. At this time, the switch 5 is assumed to connect the electrode 41 and the transceiver 6.

  The information acquisition request transmitted by the user terminal 2 is received by the transmitter / receiver 6 via the user 1, the electrode 41, and the switch 5, and reaches the host 7 via the transmitter / receiver 6 (step S201). When the transmitter / receiver 6 receives the information acquisition request, it acquires information for identifying the electrode 41 selected by the switch 5 at that time, and requests the host 7 for detailed information corresponding to the selected electrode 41.

  The host 7 that has received the information acquisition request transmits the requested detailed information to the transceiver 6 (step S202).

  The transceiver 6 that has received the detailed information from the host 7 transmits the divided data of the detailed information obtained by dividing the detailed information to the user terminal 2 through the electrode 41 and the user 1 (step S203). Of course, detailed information may be transmitted in a batch without being divided.

  The user terminal 2 that has received the divided data of the detailed information transmits an ACK indicating that the data has been received to the transceiver 6 (step S204).

  The transceiver 6 that has received the ACK transmits the divided data of the next detailed information to the user terminal 2 (Step S205), and the user terminal 2 that has received the divided data of the detailed information transmits the ACK to the transceiver 6 ( Step S206). Thus, the user terminal 2 and the transmitter / receiver 6 perform communication while confirming that the divided data has been received so that there is no data loss.

  The transmitter / receiver 6 that has finished sending all pieces of detailed information divided data transmits a completion notification to the host 7 (step S207) and waits for reception.

  When the user 1 touches the electrode 42, detailed information corresponding to the electrode 42 is sent from the host 7 to the transmitter / receiver 6 and reaches the user terminal 2 in the same manner as the above processing. When the switch 5 selects one of the plurality of electrodes 41 and 42 and connects it to the transceiver 6, the number of the transceivers 6 can be reduced. In the present embodiment, two examples of the electrodes 41 and 42 are shown. However, the present invention is not limited to this, and three or more electrodes may be arranged corresponding to the information presented on the poster 3. Of course, a plurality of posters may be arranged, and one electrode may be installed for each poster.

  FIG. 3 is a block diagram showing a configuration of another information acquisition system in the present embodiment. In the figure, only the electrodes 41 and 42, the switch 5 and the transceiver 6 are shown. The other configuration is the same as that shown in FIG. 1, and a description thereof will be omitted here.

  The switch 5 shown in FIG. 3 includes a switch 51 that selectively switches the connection between the transceiver 6 and the plurality of electrodes 41 and 42. The transceiver 6 includes a transceiver circuit 61 that performs communication and a selection circuit 62 that selects a connection destination of the switch 51 in a time division manner. The selection circuit 62 switches the switch 51 so that one of the electrodes 41 and 42 is connected to the transmission / reception circuit 61 at regular time intervals. Hereinafter, the flow of operation in which the transceiver 6 and the user terminal 2 communicate will be described.

  FIG. 4 is a sequence diagram showing a flow of processing in which the user terminal 2 acquires detailed information in the information acquisition system shown in FIG.

  As shown in FIG. 4, the selection circuit 62 controls the switch 51 to switch the connection between the electrodes 41 and 42 at regular time intervals. When the user 1 holding the user terminal 2 is not in contact with the electrodes 41 and 42, the information acquisition request does not reach the transceiver 6.

  If the user 1 contacts the electrode 42 when the electrode 42 is selected, a communication path via the user 1 and the electrode 42 is established between the user terminal 2 and the transceiver 6. As a result, the information acquisition request transmitted by the user terminal 2 is received by the transceiver 6 via the user 1, the electrode 42, and the switch 5, and reaches the host 7 via the transceiver 6 (step S401). At this time, the transmitter / receiver 6 requests the host 7 for detailed information corresponding to the electrode 42 selected by the selection circuit 62. When communication is established, the selection circuit 62 extends the selection period until communication is completed.

  The host 7 that has received the information acquisition request transmits the requested detailed information to the transceiver 6 (step S402).

  The transceiver 6 that has received the detailed information from the host 7 transmits the divided data of the detailed information obtained by dividing the detailed information to the user terminal 2 through the electrode 42 and the user 1 (step S403).

  The user terminal 2 that has received the divided data of the detailed information transmits an ACK indicating that the data has been received to the transceiver 6 (step S404).

  The transceiver 6 that has received the ACK transmits the divided data of the next detailed information to the user terminal 2 (step S405), and the user terminal 2 that has received the divided data of the detailed information transmits the ACK to the transceiver 6 ( Step S406).

  The transmitter / receiver 6 that has sent all the pieces of detailed information divided data transmits a completion notification to the host 7 (step S407), enters a reception standby state, and the selection circuit 62 switches the connection to another electrode 41.

  As described above, the selection circuit 62 controls the switch 51 to switch the electrodes 41 and 42 connected to the transmission / reception circuit 61 at regular time intervals, thereby reducing the number of the transceivers 6.

  FIG. 5 is a block diagram showing a configuration of still another information acquisition system in the present embodiment. In the figure, only the electrodes 41 and 42, the switch 5 and the transceiver 6 are shown. The other configuration is the same as that shown in FIG. 1, and a description thereof will be omitted here.

  The switch 5 shown in FIG. 5 includes a level detection circuit 52 that is connected to the plurality of electrodes 41 and 42 and acquires the reception signal level of each of the electrodes 41 and 42. When the level detection circuit 52 detects a received signal level equal to or higher than a predetermined threshold value from one of the electrodes 41 and 42, the electrode 41 and 42 and the transceiver 6 are connected to form a communication path.

  For example, when the user 1 holding the user terminal 2 contacts the electrode 41, the level detection circuit 52 detects a received signal level equal to or higher than a predetermined threshold value from the electrode 41, so that the switch 5 includes the electrode 41 and the transceiver 6. And the reception signal received by the electrode 41 is transmitted to the transceiver 6. Note that the electrodes 41 and 42 having the maximum received signal level may be connected.

  FIG. 6 is a side view showing another electrode configuration of the information acquisition system in the present embodiment. In the electrode configuration shown in the figure, since the posters 31 and 32 are arranged on both surfaces of the electrodes 41 and 42, respectively, it can be configured thinly, and it can cope with contact from either surface, so that it is like a hanging advertisement in a car. Replacement with conventional posters is possible.

  Therefore, according to the present embodiment, electrodes 41 and 42 for human body communication using the human body as a communication path are arranged on the back surface of the poster 3 and the like, and the transmitter / receiver 6 transmits detailed information by human body communication. Since the user 1 holding the user terminal 2 having the human body communication function can obtain the detailed information only by touching the poster 3, the troublesome input such as URL input and barcode recognition is eliminated. Further, by arranging the electrodes 41 and 42 in correspondence with the concise information presented on the front of the poster 3, the user 1 can select the information desired for more detailed information. , It is not unilateral information distribution. Furthermore, by switching the connection between the plurality of electrodes 41 and 42 and the transmitter / receiver 6 by the switch 5, it becomes possible to reduce the number of the transmitter / receivers 6 and to reduce the installation cost.

  Compared to the case of using a large screen display, the installation area and thickness are small, and the installation cost is low.

  Detailed information reaches the user terminal 2 even with simple advertisements with handwriting and photos, and is effective for information that changes daily (departmental advertisement, lunch menu, news distribution, etc.).

  When the user terminal 2 transmits various information of the user 1 in addition to the information acquisition request, the user 1 can perform research, and the host 7 can also provide a more detailed service according to the user 1 needs. .
