<Hardware configuration example of portable terminal device and signage device>
FIG. 2 is a diagram illustrating an example of a hardware configuration of the mobile terminal device 100 and the signage device 200. The portable terminal device 100 and the signage device 200 have the same hardware configuration.

  The mobile terminal device 100 includes a CPU 110, a first communication unit 120, a second communication unit 130, a storage 140, and a RAM (Random Access Memory) 150. Similarly, the signage device 200 includes a CPU 210, a first communication unit 220, a second communication unit 230, a storage 240, and a RAM 250. As described above, since the mobile terminal device 100 and the signage device 200 have the same hardware configuration, the following description is based on the hardware configuration of the mobile terminal device 100.

  The CPU 110 loads the program stored in the storage 140 into the RAM 150 and executes the loaded program. The CPU 110 implements the function of the control unit by executing the loaded control program 141.

The first communication unit 120 measures the distance from the signage device 200. For example, the first communication unit 120 calculates the distance from the signage device 200 from the power intensity of the radio wave received from the signage device 200. The first communication unit 120 performs wireless communication with the signage device 200. The first communication unit 120 is a communication device that supports short-range wireless communication that can perform communication at a distance of several meters to several hundred meters.

By setting the first distance in this way, the signage device 200 can be detected by the first communication unit even if the second communication unit cannot communicate. In addition, when the CPU 110 executes the control program 141 and detects a motion in response to the guidance, the CPU 110 turns on the power of the second communication unit so that the second communication unit can perform wireless communication.

  The RAM 150 is, for example, a main memory, and is an area for loading a program stored in the storage 140. The RAM 150 can also be used as an area for storing data by a program, for example.

<Processing flowchart>
FIG. 3 is a diagram illustrating an example of a processing flowchart of the wireless communication apparatus. That is, in the first embodiment, the flowchart shown in FIG. 3 is a flowchart of the mobile terminal device 100. The processing of the mobile terminal device 100 implements a control unit by the CPU 110 executing the control program 141, but the following description will be made assuming that the CPU 110 executes the processing.

  CPU110 monitors the distance with the signage apparatus 200 (P101). When the distance from the signage device 200 is not within the range of the first distance (No in P101), the CPU 110 detects that the distance from the signage device 200 is within the range of the first distance. Until then, monitoring of the distance to the signage device 200 is continued. For example, the distance from the signage device 200 is monitored by the first communication unit 120 receiving a packet transmitted from the signage device 200 and calculating the distance according to the received power of the received packet.

  When the CPU 110 detects that the distance between the first communication unit 120 and the signage device 200 is within the range of the first distance (Yes in P101), the CPU 110 communicates with the signage device 200 via the second communication unit 130. It induces to do (P102). The guidance performed by the CPU 110 enables the user of the mobile terminal device 100 to communicate with the signage device 200 via the second communication unit. The guidance performed by the CPU 110 is, for example, notifying the user of the mobile terminal device 100 of information such as the position of the signage device 200 and the antenna position of the second communication unit included in the signage device 200. For example, the position of the signage device 200 is information on longitude and latitude, and the information on the antenna position of the second communication unit included in the signage device 200 is information indicating where in the signage device 200 the antenna is located. For example, the CPU 110 outputs such information as audio or displays it as an image.

  Next, the CPU 110 monitors the movement in response to the guidance performed by the CPU 110 (P103). The movement in response to the guidance performed by the CPU 110 is, for example, that the mobile terminal device 100 is closer to the signage device 200 from the first distance, and the distance from the signage device 200 is within a distance shorter than the first distance. It is to become. The distance is shorter than the first distance, for example, the maximum distance at which the second communication unit can perform communication.

  If the CPU 110 does not detect a motion in response to the guidance performed by the CPU 110 (No in P103), the CPU 110 continues monitoring until it detects a motion in response to the guidance performed by the CPU 110. When the CPU 110 detects a motion in response to the guidance performed by the CPU 110 (Yes in P103), the CPU 110 turns on the power of the second communication unit and enters a state where communication can be performed via the second communication unit (P104).

  In the first embodiment, when the distance from the opposing device is within the range of the first distance, the wireless communication device guides communication with the opposing device via the second communication unit. By detecting the opposite device at the first communication unit capable of communicating over a distance that is longer than the communicable distance of the second communication unit, the opposite device is quickly found before the second communication unit reaches a communicable distance. Can be induced. By guiding in this way, the user of the wireless communication device can know the position of the opposite device and the position of the antenna of the opposite device before the second communication unit can communicate. Since the proximity wireless communication corresponding to the second communication unit performs communication by bringing the antennas close to several centimeters, communication cannot be performed if the positions of the antennas are shifted by several centimeters or more. Therefore, by knowing the position of the antenna of the opposing device before trying to communicate via the second communication unit, the user of the wireless communication device deviates the position of the antennas by several centimeters or more. In this case, close proximity wireless communication can be performed by holding the wireless communication device over the opposite device.

  Even if the user of the wireless communication device is not aware of the existence of the opposite device, the user can know the existence of the opposite device before reaching the communicable distance of the second communication unit. Useful for

  Furthermore, in the first embodiment, the movement in response to the guidance is regarded as the intention of the user of the wireless communication device to communicate with the opposite device via the second communication unit. In this way, it is possible to determine whether or not the user of the wireless communication device intends to communicate with the opposite device via the second communication unit, and to control the power supply of the second communication unit. That is, the second communication unit of the wireless communication device is not turned on until the user's intention to communicate with the opposite device is confirmed, so that the user's wireless communication device that desires communication with the opposite device can be powered. In addition, power saving can be realized by reducing the time during which the second communication unit is turned on.

<Modification of the first embodiment>
In the modification, the mobile terminal device 100 corresponds to the opposite device, and the signage device 200 corresponds to the wireless communication device. In the modification, the signage device (wireless communication device) 200 detects that the distance from the mobile terminal device (opposite device) 100 has become the first distance. Hereinafter, the operation of the modification will be described using the flowchart of the wireless communication apparatus shown in FIG. 3, that is, the flowchart of the signage apparatus 200.

  When the signage device (wireless communication device) 200 detects that the distance from the mobile terminal device (opposite device) 100 is within the first distance range (Yes in P101), the second communication unit 230 is used. Then, the mobile terminal device (opposite device) 100 is guided to communicate (P102). Guidance in the modified example includes, for example, information such as the position of the signage device (wireless communication device) 200 and the antenna position of the second communication unit included in the signage device (wireless communication device) 200 as the mobile terminal device (opposite device) 100. To request to be displayed. That is, the guidance in the modified example informs the user of the mobile terminal device (opposite device) 100 of the position of the signage device (wireless communication device) 200 and the position of the antenna of the wireless signage device (wireless communication device) 200. That is.

  Next, when the signage device (wireless communication device) 200 detects a movement in response to the guidance, the second communication unit 230 is turned on. The movement in response to the guidance in the modified example is that the mobile terminal device (opposite device) 100 further approaches the signage device (wireless communication device) 200, and the distance from the mobile terminal device (opposite device) 100 is within the second distance range. To be inside.

  The modification differs from the first embodiment in the contents of guidance. In both cases, the guidance is directed to the user of the portable terminal device 100, but in the first embodiment, the guidance is directed to the user of the wireless communication device (the portable terminal device 100). This is guidance for the user of the opposing device (mobile terminal device 100). However, also in the modification, the first embodiment is different from the first embodiment in that the user of the mobile terminal device 100 is notified of information such as the position of the signage device 200 and the antenna position of the second communication unit included in the signage device 200. The same. Therefore, as in the first embodiment, the user of the mobile terminal device 100 performs close proximity wireless communication by holding the mobile terminal device 100 over the signage device 200 without shifting the position of the antennas by several centimeters or more. Can do. In addition, even if the user of the mobile terminal device 100 is unaware of the presence of the signage device 200 as in the first embodiment, the user knows the presence of the signage device 200 before reaching the range where close proximity wireless communication is possible. This is beneficial to the user of the mobile terminal device 100. Furthermore, since the processes other than the guidance are the same processes, power saving can be realized as in the first embodiment.

  In each of the following embodiments, the mobile terminal device 100 and the signage device 200 will be described. A device that detects that the distance is within the range corresponding to the first distance is a wireless communication device, and a device that performs wireless communication with the wireless communication device is a counter device. Depending on the embodiment, whether the mobile terminal device 100 or the signage device 200 corresponds to a wireless communication device or a counter device is different. Hereinafter, the correspondence relationship will be described for each embodiment. For example, the correspondence relationship may be described in parentheses, such as “mobile terminal device (wireless communication device) 100”.

[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, as in the modification of the first embodiment, the signage device 200 corresponds to a wireless communication device, and the mobile terminal device 100 corresponds to a counter device. The signage device 200 detects that the mobile terminal device 100 is nearby (distance X1), and guides the user of the mobile terminal device 100 to communicate with the signage device 200. The guidance performed by the signage device 200 is to display information on the signage device 200 and the antenna position of the signage device 200 on the display unit of the mobile terminal device 100.

  Hereinafter, the sequence of FIG. 6 will be described with reference to the flowchart of FIG. Note that the processing of the mobile terminal device 100 and the signage device 200 is realized by the CPU 110 or 210 executing the control program 141 or the control program 241, but the following description is based on the assumption that the CPU 110 or CPU 210 executes the processing. To do.

  The signage device 200 sets the mobile terminal device 100 to make a Bluetooth connection when the distance from the mobile terminal device 100 becomes X1 or less (P251). The Bluetooth communication unit 220 of the signage device 200 waits until it detects that the distance from the mobile terminal device 100 is within the range of X1 (S200).

  When the Bluetooth communication unit 220 of the signage device 200 detects that the distance from the mobile terminal device 100 is within the range of X1 (Yes in S200), the Bluetooth communication unit 220 establishes a Bluetooth connection with the mobile terminal device 100 (S201).

  The Bluetooth communication unit 220 of the signage device 200 notifies the CPU 210 that the distance from the mobile terminal device 100 is within the range of X1 (S202). Upon receiving the notification, the CPU 210 transmits an antenna position information display request to the mobile terminal device 100 via the Bluetooth communication unit 220 in order to request to display the antenna position information on the mobile terminal device 100 (S203, S204). ).

  On the other hand, when the Bluetooth connection is established (S201), the mobile terminal device 100 waits for an antenna position information display request from the signage device 200. And CPU110 of the portable terminal device 100 will transmit an antenna position information display request to the display part 160, if the antenna position information display request is received from the signage apparatus 200 via the Bluetooth communication part 120 (S206). ). Upon receiving the antenna position information display request, the display unit 160 of the mobile terminal device 100 displays the antenna position information (S206).

When the CPU 110 receives the notification, it transmits a close proximity wireless communication section power ON request to the close proximity wireless communication section 130 and turns on the close proximity wireless communication section 130 (S211).

  Similarly, when the Bluetooth communication unit 220 of the signage device 200 detects that the distance from the mobile terminal device 100 is within the range of X2 (Yes in S207), the CPU 210 causes the distance from the mobile terminal device 100 to be X2. The fact that it is within the range is notified (S208). When the CPU 210 receives the notification, the CPU 210 transmits a close proximity wireless communication unit power-on request to the close proximity wireless communication unit 230 and turns on the close proximity wireless communication unit 230 (S209).

  After that, when the distance between the mobile terminal device 100 and the signage device 200 is a distance at which communication is possible via the proximity wireless communication units 130 and 230, the proximity wireless communication units 130 and 230 are connected to each other for proximity wireless communication. Is established (S212). When the connection is established, content data is transmitted from the signage device 200 to the mobile terminal device 100 (S213).

  In the second embodiment, when the signage device (wireless communication device) 200 is within the range of X1 with the mobile terminal device (opposite device) 100, the antenna position information of the signage device 200 is transmitted to the mobile terminal device 100. Send and display. In this way, the user of the mobile terminal device 100 is guided to perform close proximity wireless communication with the signage device 200. The guided user of the mobile terminal device 100 can know the position of the antenna 231 included in the signage device 200 and can perform close proximity wireless communication smoothly. Further, even when the user of the mobile terminal device 100 is unaware of the presence of the signage device 200, it is possible to know the presence of the signage device 200 by this guidance, which is beneficial for the user of the mobile terminal device 100. It is.

  Further, by using the antenna position information as an image, the user of the mobile terminal device 100 has the antenna 231 installed in the signage device 200 as compared with the case where the antenna position is notified by voice, for example. There is an advantage that it becomes easy to understand.

  Furthermore, an image around the signage device 200 may be included in the antenna position information. An image around the signage device 200 is captured by the imaging unit 170 of the mobile terminal device 100. For example, when the antenna position information display request includes the position information of the signage device 200, the image capturing unit 170 determines the direction in which the signage device 200 is installed from the position information, and takes a photograph. Further, the CPU 110 combines the photographed image and the antenna position information image received from the signage device 200 and displays the combined image on the display unit 160 as one image. By doing in this way, the user of the portable terminal device 100 can be notified of the position of the signage device 200 itself more easily.

  FIG. 9 is a diagram illustrating an example of an image synthesized by the CPU 110. Similar to the example of the antenna position information shown in FIG. 8, the line indicated by F <b> 1 represents the shape of the signage device 200, and there is an antenna F <b> 2 indicated by diagonal lines below the display unit of the signage device 200. In FIG. 9, there is an image F <b> 3 around the signage device 200 indicated by a lattice pattern. Thus, for example, when the user of the mobile terminal device 100 searches for the signage device 200, the signage device 200 can be easily found by having an image around the signage device 200.

  Also in 2nd Embodiment, when the distance with the portable terminal device 100 becomes X1, the user of the portable terminal device 100 is induced | guided | derived by transmitting and displaying antenna position information. By detecting the movement in response to this guidance, that is, when the distance from the mobile terminal device 100 becomes closer, it is considered that the user of the mobile terminal device 100 intends to communicate with the signage device 200. . In this way, it is determined whether or not the user of the mobile terminal device 100 has an intention to communicate with the signage device 200, and when it is determined that there is an intention, the power of the close proximity wireless communication unit is controlled to be ON. That is, the user of the mobile terminal device 100 intends to communicate with the signage device 200 without turning on the power of the proximity wireless communication unit until the user's intention to communicate with the signage device is confirmed. Since the power can be turned on in the case of having power, power saving can be realized.

  Furthermore, as a wireless communication standard used by the close proximity wireless communication units 130 and 230, it is desirable to use Bluetooth Low Energy, which is a standard that realizes low power of Bluetooth. The signage device 200 measures the distance from the mobile terminal device 100 via the Bluetooth communication unit 220. At this time, the Bluetooth communication unit 220 continues to search for Bluetooth packets notified from the mobile terminal device 100, and calculates the distance based on the received power of the searched packets. Compared with normal Bluetooth, Bluetooth Low Energy can search for a Bluetooth packet notified from the mobile terminal device 100 with low power, and thus can realize further power saving.

  Further, when the signage device 200 receives the antenna position information acquisition request from the mobile terminal device 100, the signage device 200 authenticates the mobile terminal device 100 and transmits an antenna position information display request to the mobile terminal device 100 according to the authentication result. Good. The authentication is performed by, for example, registering the identifier of the mobile terminal device 100 in the signage device 200 in advance and comparing whether the identifier of the mobile terminal device 100 that transmitted the antenna position information acquisition request is registered. When the identifier of the mobile terminal device 100 is registered, an antenna position information display request is transmitted to the mobile terminal device 100. By doing so, it is possible to reduce the possibility of the portable terminal device 100 having low reliability accessing the signage device 200 without guiding the portable terminal device 100 having low reliability unregistered in the signage device 200. , Improve security.

In addition, the Bluetooth communication unit 120 communicates to the CPU 110 that it has detected that the distance from the signage device 200 is equal to or less than X1 (S252).

  When the CPU 110 receives a notification that the distance from the signage device 200 is less than or equal to X1, the CPU 110 transmits an antenna position information acquisition request to the signage device 200 via the Bluetooth communication unit 120 in order to acquire the antenna position information ( S253, S254).

  When receiving the antenna position information acquisition request via the Bluetooth communication unit 220 (S254, S255), the CPU 210 of the signage device 200 transmits the antenna position information to the mobile terminal device 100 via the Bluetooth communication unit 220 ( S203, S204).

  Hereinafter, the sequence of FIG. 13 will be described with reference to the flowchart of FIG. Note that the processing of the mobile terminal device 100 and the signage device 200 is realized by the CPU 110 or 210 executing the control program 141 or the control program 241, but the following description is based on the assumption that the CPU 110 or CPU 210 executes the processing. To do. Further, sequences other than the sequence surrounded by G2 shown in FIG. 13 are the same as the sequences shown in FIG. 6 of the second embodiment. Therefore, here, a sequence surrounded by G2 will be described.

    The signage device 200 sets the mobile terminal device 100 to make a Bluetooth connection when the distance from the mobile terminal device 100 becomes X1 or less (P351). The Bluetooth communication unit 220 of the signage device 200 waits to detect that the distance from the mobile terminal device 100 is within the range of X1 (S300).

  When the Bluetooth communication unit 220 of the signage device 200 detects that the distance from the mobile terminal device 100 is within the range of X1 (Yes in S300), the Bluetooth communication unit 220 establishes a Bluetooth connection with the mobile terminal device 100 (S301).

  The Bluetooth communication unit 220 of the signage device notifies the CPU 210 that the distance from the mobile terminal device 100 is within the range of X1 (S302). Upon receiving the notification, the CPU 210 requests that the antenna position information be displayed on the display unit 260 (S303), and the display unit 260 displays the antenna position information.

<Configuration example of portable terminal device>
FIG. 15 is a diagram illustrating an example of a hardware configuration of the mobile terminal device 100.

FIG. 16 is a diagram illustrating an example of a sequence from when the mobile terminal device 100 detects that the distance from the signage device 200 is within the range of X1 to when content is transmitted from the signage device 200 to the mobile terminal device 100. It is.

  FIG. 17 is a diagram illustrating an example of a flowchart of processing until the portable terminal device 100 and the signage device 200 turn on the power of the close proximity wireless communication units 130 and 230.

  Hereinafter, the sequence of FIG. 16 will be described with reference to the flowchart of FIG. Note that the processing of the mobile terminal device 100 and the signage device 200 is realized by the CPU 110 or 210 executing the control program 141 or the control program 241, but the following description is based on the assumption that the CPU 110 or CPU 210 executes the processing. To do. Also, sequences other than the sequence surrounded by G3 shown in FIG. 17 are the same as the sequences of the modified example of the second embodiment. Therefore, here, a sequence surrounded by G3 will be described.

  CPU110 of the portable terminal device 100 will turn ON the power supply of the acceleration measurement part 180, if an antenna position information display request (S206) is transmitted (S400). If the acceleration device is already on, S400 can be omitted.

  The acceleration measuring unit 180 detects an acceleration of Y1 meter per second or more (S401), and notifies the CPU 110 of the acceleration detection information (S402). The CPU 110 receives S402 and turns on the power of the close proximity wireless transfer unit 130 (S403). Y1 is, for example, a value of acceleration that occurs when the user of the mobile terminal device 100 moves the mobile terminal device 100 over the signage device 200 when performing close proximity wireless communication with the signage device 200.

  In the fourth embodiment, a certain acceleration is applied to the mobile terminal device 100 in response to the guidance. When a certain acceleration is applied to the mobile terminal device 100, it is considered that the user of the mobile terminal device 100 moves the mobile terminal device 100 over the signage device 200. That is, the movement of holding the mobile terminal device 100 over the signage device 200 means that the user of the mobile terminal device 100 is willing to communicate with the signage device 200. In the fourth embodiment, the proximity wireless communication unit 130 is turned on when the user's intention is detected, and the same effect as in the second embodiment can be obtained.

  Moreover, the portable terminal device 100 may have an angle measurement part. The angle measurement unit measures the inclination of the mobile terminal device 100 with respect to the ground. The angle measuring unit is, for example, a gyro sensor. When the angle measuring unit measures that the inclination of the portable terminal device 100 is within a certain angle range, the portable terminal device 100 turns on the proximity wireless communication unit 130. The certain angle is a range of angles centered on the antenna installation angle of the signage device 200. For example, when the antenna of the signage device 200 is installed perpendicular to the ground, that is, 90 degrees from the ground, the certain angle is in the range of 80 degrees to 100 degrees, with an allowable range of 10 degrees before and after 90 degrees. It becomes.

  Thus, when the inclination of the mobile terminal device 100 falls within a certain angle range, the user of the mobile terminal device 100 tries to match the inclination of the mobile terminal device 100 with the angle of the antenna of the signage device 200. It can be assumed that the movement responds to the guidance.

  Note that the mobile terminal device 100 may include an angle measurement unit instead of the acceleration measurement unit 180, or may include both the angle measurement unit and the acceleration measurement unit 180. When both the angle measuring unit and the acceleration measuring unit 180 are provided, the movement in response to the guidance is both that the mobile terminal device is subjected to a certain acceleration and the inclination of the portable terminal device is within a certain angle range. Will be detected.

The configuration of the signage device 200 is the same as the configuration of the signage device shown in FIG. 5 in the second embodiment.

<Processing flowchart>
FIG. 20 is a diagram illustrating an example of a sequence from when the mobile terminal device 100 detects that the distance from the signage device 200 is within the range of X1 to when content is transmitted from the signage device 200 to the mobile terminal device 100. It is.

  FIG. 21 is a diagram illustrating an example of a flowchart of processing until the mobile terminal device 100 and the signage device 200 turn on the proximity wireless communication units 130 and 230.

  Hereinafter, the sequence of FIG. 20 will be described with reference to the flowchart of FIG. Note that the processing of the mobile terminal device 100, the signage device 200, and the data server 300 implements a control unit by the CPUs 110, 210, and 310 executing the control program, but thereafter the CPUs 110, 210, and 310 perform the processing. Will be described. Further, sequences other than the sequence surrounded by G4 shown in FIG. 20 are the same as the sequences of the modified example of the second embodiment. Therefore, the sequence surrounded by G4 will be described here.

  When notified from the Bluetooth communication unit 120 that the distance from the signage device 200 is within the range of X1 (S252), the CPU 110 of the mobile terminal device 100 transmits an antenna position information acquisition request to the data server 300. (S500, S501). The antenna position information acquisition request includes an identifier that uniquely indicates the signage device 200. The identifier is, for example, a UUID (Universally Unique Identifier).

  The CPU 310 of the data server 300 receives the antenna position information acquisition request via the network communication unit 390 (S501, S502).

The CPU 310 transmits the antenna position information to the mobile terminal device 100 via the network communication unit 390 (S503, S504).

  When receiving the antenna position information via the network communication unit 190 (S504, S505), the CPU 110 of the mobile terminal device 100 transmits an antenna position information display request to the display unit 160 to display the antenna position information (S506). ).
