This display screen 151 includes an image of a character string “Please direct the laser emission light toward the device where the light is turned on and press the transmission button.” And an image of the transmission button 155. Then, the user holding the user terminal 200a presses the image of the transmission button 155 with the laser emission light (the emission port of the highly directional communication means) directed toward the device where the light is lit.

  In response to this pressing, the user terminal 200a transmits the same specific signal as the specific signal transmitted in S33 to the shared device 300a using the high directivity communication unit 170 (S37).

  After the light is turned on (S31), the shared device 300a receives the specific signal using the high directivity communication unit 270 (S39), and uses the short-range communication unit 260 to transmit the received specific signal to the user terminal 200a. (S41).

  The user terminal 200a determines whether or not the specific signal transmitted using the high directivity communication unit 270 is the same as the specific signal (reply signal) returned from the shared device 300a (S45). If the transmitted specific signal and the reply signal are the same, the shared device 300a to which the user having the user terminal 200a points the laser emission port is the shared device 300a to which the guidance server 100a transmits a Bluetooth passkey. It is authenticated.

  On the other hand, if the reply signal cannot be received, the shared device 300 to which the user having the user terminal 200a points the laser emission port is not the shared device 300a to which the guidance server 100a transmits the Bluetooth passkey. That is, the shared device 300a receives the light turn-on request (S29), and the shared device 300a turns on the light. For example, a third party device turns on the light at the same time.

  If the user points the laser emission port toward the third party device, the user terminal 200a cannot receive a reply signal using Bluetooth. As a result, the user terminal 200a repeats the determination until the specific signal and the reply signal are the same (No in S45). The user terminal 200a transmits the determination result as an authentication result to the guidance server 100a (S47).

  On the other hand, the shared device 300a compares the specific signal received by the high directivity communication unit 270 with the specific signal received by the NW communication unit 230 (S49). That is, the shared device 300a determines whether or not the specific signal received by the high directivity communication unit 270 is the same as the specific signal received by the NW communication unit 230 (S49). If they are not identical (not identical in S49), the shared device 300a repeats the comparison until it is determined to be identical. If the shared device 300a is the same (same in S49), the comparison result indicating that it is the same is transmitted as an authentication result to the guidance server 100a (S51). The guidance server 100a receives the authentication result from the user terminal 200a and the shared device 300a (S53).

(Second Embodiment)
In the guidance system 1 of the first embodiment, the user specifies the shared device 300a by turning on the light of the shared device 300a. However, the shared device 300 captures a surrounding image, and the user displays the user terminal 200. The shared device can be specified by analyzing the video displayed on the means.

(Description of configuration)
The configuration of the guidance system 1 is the same as that shown in FIGS. 1 and 2, the guidance server 100a is changed to the guidance server 100b, the user terminal 200a is changed to the user terminal 200b, and the shared device 300a is changed to the shared device 300b. In particular, the shared device 300b is added with a photographing unit 280, and the control unit 210 is added with a photographing control unit 218. The shared device 300b does not require the light emission means 250, and the control means 210 does not require the function of the light emission control means 217.

(Description of operation)
5A and 5B are flowcharts for explaining the operation of the guidance system according to the second embodiment of the present invention.
First, the user terminal 200b issues a guidance instruction to the guidance server 100b and transmits position information (S61). At this time, the user terminal 200b detects the current position using the position detection unit 140, and transmits position information (GPS data) to the guidance server 100b. The guidance server 100b issues a GPS data transmission instruction to the shared device 300b (S63). The shared device 300b detects the current position using the position detection unit 240 (S65).

  While the guidance server 100b mediates position information (S69), the shared device 300b transmits and receives position information (GPS data) (S67), and the user terminal 200b receives the position information (S71). That is, the shared device 300b transmits its own location information to the guidance server 100b and receives the location information of the user terminal 200a from the guidance server 100b. Further, the user terminal 200b receives the position information of the shared device 300b from the guidance server 100b. When receiving the location information of the shared device 300b, the user terminal 200b displays the location information of the shared device 300b on the display unit 150 (S73).

  The guidance server 100b transmits a Bluetooth passkey to both the user terminal 200b and the shared device 300b (S75). Then, the user terminal 200b and the shared device 300b receive the Bluetooth passkey (S77, S79). Here, the guidance server 100b may perform either position information mediation (S69) or Bluetooth passkey transmission (S75) first.

  When the position information of the shared device 300b is displayed on the display unit 150 (S73), the user approaches the displayed shared device 300b (S81). As the user terminal 200b and the shared device 300b approach each other, Bluetooth short-range communication is established (S83, S85).

  Next, when the Bluetooth short-range communication is established, the shared device 300b uses the photographing unit 280 (FIG. 1) and the photographing control unit 218 (FIG. 2) to photograph the entire circumference (S87). The captured video signal is transmitted to the user terminal 200b (S89).

  The user terminal 200b receives the video signal (S91) and displays the video on the display means 150 (FIG. 1) (S93). The user possessing the user terminal 200b analyzes the displayed video and specifies a shared device (S95). That is, the user identifies the shared device by comparing the visually observed scene with the displayed video.

  Next, in FIG. 5B, the user terminal 200b transmits a specific signal to the shared device 300b using the NW communication unit 130 (S97), and the shared device 300b receives the specific signal using the NW communication unit 230. (S101).

  Next, the user terminal 200b displays the display screen 152 (FIG. 6) on the display means 150 (FIG. 1). This display screen 152 includes an image of a character string “Please direct the laser emission light toward the device inferred from the video and press the transmission button.” And an image of the transmission button 155. Here, the laser emission light means the emission port of the highly directional communication means 170. Then, the user possessing the user terminal 200b presses the image of the transmission button 155 with the laser emission light directed toward the estimated device.

  In response to this pressing, the user terminal 200b transmits the same specific signal as the specific signal transmitted in S33 to the shared device 300b using the high directivity communication unit 170 (S99).

  The shared device 300b receives the specific signal using the high directivity communication unit 270 (S103) after shooting the video (S87), and transmits the received specific signal to the user terminal using the short-range communication unit 260. Reply to 200b (S105).

  The user terminal 200b determines whether or not the specific signal transmitted using the high directivity communication unit 270 is the same as the specific signal (return signal) returned from the shared device 300b (S109). If the transmitted specific signal and the reply signal are the same, the device to which the user having the user terminal 200b points the laser emission port is the shared device 300b to which the guidance server 100b transmits the Bluetooth passkey. Authenticated.

  On the other hand, if the reply signal cannot be received, the device to which the user having the user terminal 200b points the laser emission port is not the shared device 300b to which the guidance server 100b transmits the Bluetooth passkey. If the user points the laser emission port toward the other device, the user terminal 200b cannot receive a reply signal using Bluetooth. As a result, the user terminal 200b repeats the determination until the specific signal and the reply signal are the same (No in S109). The user terminal 200b transmits the determination result as an authentication result to the guidance server 100b (S111).

  On the other hand, the shared device 300b compares the specific signal received by the high directivity communication unit 270 with the specific signal received by the NW communication unit 230 (S113). That is, the shared device 300b determines whether or not the specific signal received by the high directivity communication unit 270 is the same as the specific signal received by the NW communication unit 230 (S113). If they are not identical (not identical in S113), the shared device 300b repeats the comparison until it is determined to be identical. If the shared device 300b is the same (same in S113), the comparison result indicating that it is the same is transmitted as an authentication result to the guidance server 100b (S115). The guidance server 100b receives the authentication result from the user terminal 200b and the shared device 300b (S117).

(Comparative example)
The guidance system 1 according to the first embodiment uses the highly directional communication means 170 and 270 to transmit a specific signal to the shared device whose light is turned on. Hereinafter, a comparative example compared with the guidance system 1 will be described with reference to FIGS.

FIG. 7 is a conceptual diagram of a guidance system that is a comparative example of the present embodiment.
The guidance system 1c includes a guidance server 100c, a user terminal 200c, and a shared device 300c, and the user terminal 200c and the shared device 300c are communicably connected to the guidance server 100c via the NW. Further, the user terminal 200c and the shared device 300c can perform near field communication by Bluetooth. The guidance server 100c has a function of notifying each other of positional information and identification information of the user terminal 200c and the shared device 300c via the NW, and notifying a short-range communication pass key. The shared device 300c has a function of turning on a light.

  That is, the guidance system 1c is different from the guidance system 1a of the first embodiment in that it does not have a function of highly directional communication.

  When the user having the user terminal 200c approaches the shared device 300c, the short-range communication by Bluetooth is established. The shared device 300c turns on the light by establishing the short-range communication. The user identifies the shared device 300c by viewing the lighting of the light.

FIG. 8 is an explanatory diagram for explaining the problem of the guidance system which is a comparative example of the present invention.
In the guidance system 1c illustrated in FIG. 8, an unauthorized device 301 exists in addition to the user terminal 200c and the shared device 300c. The unauthorized device 301 is arranged in the vicinity of the shared device 300c. For example, the unauthorized device 301 detects that the shared device 300c is turned on, and the light is turned on simultaneously with the detection. In FIG. 8, the guidance server 100c that performs NW communication between the user terminal 200c and the shared device 300c is omitted.

  The unauthorized device 301 turns on the light when the light of the shared device 300c is turned on. For this reason, there is a problem that the user who owns the user terminal 200c misidentifies that the unauthorized device 301 is a device guided by the guidance server 100c and uses the unauthorized device 301.

  On the other hand, in the guidance system 1a of the present embodiment, the user terminal 200a transmits a specific signal to the shared device 300a using the high directivity communication unit 170 (FIG. 1), and the short-range communication unit 160 by Bluetooth is used. It is configured to check (authenticate) whether or not a specific signal has been returned. For this reason, even if the user who owns the user terminal 200a does not return a specific signal even if the laser emission port is pointed at the unauthorized device 301, the laser is always applied to the shared device 300c whose light is turned on. The launch port will be turned.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications such as the following are possible.
(1) In the guidance system 1b according to the second embodiment, the image capturing unit 280 (FIG. 1) of the shared device 300b captures a surrounding image using the communication establishment (S85) of the short-range communication unit 160 as a trigger (FIG. 1). 5A S87). When the photographing unit 280 always captures a surrounding image and recognizes a person (not necessarily a user), the shared device 300b may transmit a video signal to the user terminal 200b.

  In this case, when the user who owns the user terminal 200b recognizes that the user has approached the shared device 300b, he / she confirms the video displayed on the display unit 150 (FIG. 1). In the case of this modification, the shared device 300b may transmit to the user terminal 200b without using the short-range communication means 160 and 260 or via a network. This is because the highly directional communication means 170 and 280 for transmitting the specific signal must be in a short distance.

(2) In the guidance system 1b of the second embodiment, the user (human) analyzes the video captured by the imaging unit 280 (FIG. 1), and specifies the shared device 300. In the user terminal 200b, the control unit 110 (FIG. 1) may specify the shared device 300 by comparing the video captured by its own camera with the video of the video signal received from the shared device 300.
