Description

  The present invention relates to an alignment assisting device and an alignment assisting method.

  In recent years, wireless traffic has increased rapidly due to the spread of smartphones and wireless LAN (Local Area Network), and high definition of images and moving images transmitted wirelessly, and the frequency band in the microwave band has become a problem. For this reason, there is a demand for further speeding up of the wireless communication system, and in order to meet the needs, the use of a millimeter wave band capable of ultra-high speed wireless transmission using abundant frequency bands is being studied. For example, in the 60 GHz band, a 9 GHz wide band can be used without a radio station license in Japan, and standardization of millimeter wave wireless standards such as IEEE802.11ad and WirelessHD (registered trademark) has been promoted. Frequency band.

  As a use case of a wireless communication system using the millimeter wave band, in-room communication with a communication distance of several meters, or non-contact communication (communication) between the information terminal (for example, kiosk terminal 500) shown in FIG. The distance of several centimeters) has been studied. In the former (in-room communication), applications such as in-house AV (Audio Visual) devices and PCs (Personal Computers) and peripheral devices are wirelessly connected, and high-definition video transmission and large-capacity file transmission are considered. . In the latter case (non-contact communication), the user holds a mobile terminal over a kiosk terminal installed in a public facility such as a street, a station, or an airport, or a store such as a convenience store, and large-capacity content such as electronic books, music, and movies. A service that downloads files instantly is being considered.

  As described above, the 60 GHz band can be used without a radio station license, but for that purpose, the transmission power needs to be 10 mW or less. In addition to this restriction, millimeter waves are characterized by a larger propagation loss than microwaves. Therefore, in general, high-gain directional antennas and beam forming technology are used to direct beams between transceivers for communication. Do. Millimeter-wave wireless standards such as IEEE802.11ad are mainly targeted for in-room communication. In this use case, the optimum beam direction differs depending on the positional relationship between the transmitter and the receiver, and therefore, a beamforming technique is adopted.

  According to Non-Patent Document 1, when beam forming is used, a training period is required for the transceivers to direct beams in the directions of each other before transmitting information data. However, since non-contact communication is a one-to-one communication between a kiosk terminal and a portable terminal, a communication speed of several Gbit / s is guaranteed, and large-capacity content can be downloaded instantaneously. If the transmission speed is thus improved and the content download time is shortened, the training period for beam forming becomes relatively long, which becomes a problem.

  Here, when considering the use form of non-contact communication, the positional relationship of the transceiver is limited to some extent when the user holds the portable terminal over an information terminal (for example, a kiosk terminal) to be communicated, so it is necessary to use beam forming. There is no. When a fixed beam directional antenna is used for transmission / reception, the above-described training period is not required, and more efficient content download is possible.

IEEE P802.11ad Draft Std, D2.0, “9.25 DBAND BEAMFORMING”, pp. 226-264, March 2011

  In contactless communication using a fixed beam directional antenna, when the user holds the portable terminal over the kiosk terminal, the antennas of the portable terminal and the kiosk terminal may be misaligned due to the following factors.

  For example, as illustrated in FIG. 4A, it is assumed that the portable terminal 100 is held over the touch unit 520 provided with the antenna 530 of the kiosk terminal 500. FIG. 4B is a diagram showing the back surface of the mobile terminal 100, and shows that the antenna 130 of the mobile terminal 100 is provided on the back surface side. At this time, a space between the touch unit 520 of the kiosk terminal 500 and the portable terminal 100 becomes a blind spot from the user, and the positions of the antenna 530 of the kiosk terminal 500 and the antenna 130 of the portable terminal 100 may not be visually confirmed. This can be dealt with by changing the viewpoint so that the user can see both antennas of the kiosk terminal 500 and the portable terminal 100. However, in consideration of user convenience, it is desirable that alignment can be performed more easily. .

  FIG. 5 shows an example in which a terminal installation guide 621 indicating the position when the mobile terminal 100 is installed is provided on the touch unit 620 of the kiosk terminal 600. In addition, FIG.5 (b) is the figure which expanded and showed the touch part 620 of the kiosk terminal 600 shown to Fig.5 (a). A method of preventing the position of the antenna 630 of the kiosk terminal 600 from shifting to the position of the antenna 130 of the portable terminal 100 by allowing the portable terminal 100 to be placed along the terminal installation guide 621 is also conceivable. . However, since the position of the antenna 130 on the back surface of the mobile terminal 100 varies depending on the model of the terminal, the position of the antenna between the kiosk terminal 500 and the mobile terminal 100 is shifted depending on the model.

  If the antennas are displaced from each other due to such factors, the communication quality may be deteriorated because communication cannot be performed with the beams of the antennas facing each other. For example, content may not be downloaded.

  The present invention has been made in view of such circumstances, and its purpose is to provide a user with an information terminal (for example, a kiosk terminal) to be communicated in non-contact communication using a fixed beam directional antenna.

The smaller the positional deviation between the antenna of the mobile terminal and the antenna of the information terminal detected from the image, the stronger the wind output from the blower or the higher the frequency of wind output. It is characterized by controlling to.

It is explanatory drawing which shows the positioning method of the antenna using the terminal installation guide.

  Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment>
FIG. 1 is a configuration diagram illustrating an example of a schematic configuration of a contactless communication system 1 according to the first embodiment of the present invention. The non-contact communication system 1 includes a mobile terminal 100 and a kiosk terminal 200 including the alignment assisting device 300 according to the present embodiment.

  The mobile terminal 100 includes an antenna 130, a transmission unit 150, a reception unit 160, and a switching unit 170. The antenna 130 is, for example, a fixed beam directional antenna for transmitting and receiving data to and from the kiosk terminal 200 by wireless communication using a millimeter wave band. In the example shown in this figure, the antenna 130 is provided so as to radiate radio waves from the back side of the mobile terminal 100. The transmission unit 150 supplies transmission data to the antenna 130, and the reception unit 160 receives reception data received by the antenna 130. The switching unit 170 switches between a state where the antenna 130 and the transmission unit 150 are connected and a state where the antenna 130 and the reception unit 160 are connected.

  For example, when the mobile terminal 100 receives data from the kiosk terminal 200, the mobile terminal 100 controls the switching unit 170 so that the antenna 130 and the receiving unit 160 are connected, and transmits data to the kiosk terminal 200. The switching unit 170 is controlled so that the antenna 130 and the transmission unit 150 are connected.

  The kiosk terminal 200 is an example of an information terminal installed in a street, a public facility, or a store. The kiosk terminal 200 transmits data to the mobile terminal 100 or performs mobile communication by performing contactless communication with the user's mobile terminal 100. Data is received from the terminal 100. For example, the user can hold the mobile terminal 100 over the kiosk terminal 200 and download or upload data by non-contact communication.

The kiosk terminal 200 illustrated in FIG. 1A includes a display 210, a touch unit 220, an antenna 230, a transmission unit 250, a reception unit 260, a switching unit 270, and an alignment assisting device 300. Yes.
The display 210 is a touch panel display that can be operated by a user touching the screen, for example, and displays content that can be used on the kiosk terminal 200. The touch unit 220 is provided with an antenna 230 for performing non-contact communication with the mobile terminal 100. That is, the touch part 220 is a position where the kiosk terminal 200 performs non-contact communication with the mobile terminal 100.

  The antenna 230 is, for example, a fixed beam directional antenna for transmitting and receiving data to and from the mobile terminal 100 by wireless communication using a millimeter wave band. The transmission unit 250 supplies transmission data to the antenna 230, and the reception unit 260 receives reception data received by the antenna 230. The switching unit 270 switches between a state where the antenna 230 and the transmission unit 250 are connected and a state where the antenna 230 and the reception unit 260 are connected.

  For example, when the kiosk terminal 200 receives data from the mobile terminal 100, the kiosk terminal 200 controls the switching unit 270 so that the antenna 230 and the receiving unit 260 are connected, and transmits data to the mobile terminal 100. The switching unit 270 is controlled so that the antenna 230 and the transmission unit 250 are connected.

  Specifically, for example, in the case of downloading from the kiosk terminal 200 to the portable terminal 100, the transmission unit 250 of the kiosk terminal 200 generates a transmission signal of a content data series by processing such as encoding and modulation, The generated transmission signal is output to the antenna 230 when the switching unit 270 is connected to the antenna 230 and the transmission unit 250. The antenna 230 wirelessly transmits the transmission signal output from the transmission unit 250 to the mobile terminal 100. In addition, the antenna 130 of the mobile terminal 100 receives a radio signal wirelessly transmitted from the antenna 230 of the kiosk terminal 200 in a state where the switching unit 170 is connected to the antenna 130 and the receiving unit 160, and Output. The receiving unit 160 performs processing such as demodulation and decoding on the signal received by the antenna 130 to restore the content data series.

The alignment assisting device 300 includes a blower 310, a storage unit 320, a camera 330, and a control unit 350.
The blower 310 has a function as a notification unit that notifies the degree of positional deviation between the antennas of the kiosk terminal 200 and the mobile terminal 100. For example, the blower 310 includes a blower port 315 and outputs (blows) wind from the blower port 315.

  When the user holds the portable terminal 100 over the touch unit 220 in order to perform non-contact communication with the kiosk terminal 200 (for example, to use for downloading content), the blower port 315 is connected from the touch unit 220 to the portable terminal 100. It is provided in the touch part 220 so that a wind is output toward the direction. Note that the air blowing port 315 may be disposed in the vicinity of the touch unit 220. That is, the blower 310 is provided corresponding to the position where the kiosk terminal 200 performs non-contact communication.

  The blower 310 outputs wind from the blower opening 315 or stops the wind output under the control of the control unit 350. Further, the blower 310 changes the strength of the wind output from the blower opening 315 under the control of the control unit 350.

  The storage unit 320 stores control information related to control performed in the alignment assisting device 300. For example, the storage unit 320 stores control information for controlling the wind output from the blower 310. This control information is, for example, control information indicating the strength of the wind output from the blower 310, which is controlled according to the displacement of the antenna positions of the mobile terminal 100 and the kiosk terminal 200.

  The camera 330 is an imaging device provided in the vicinity of the touch unit 220 and photographs the mobile terminal 100 held over the touch unit 220. For example, the camera 330 outputs an image obtained by photographing the back surface of the mobile terminal 100 held over the touch unit 220 to the alignment assisting device 300. The camera 330 may be provided in the touch unit 220.

The control unit 350 controls the wind output from the blower 310 based on the degree of positional deviation between the antenna 230 of the kiosk terminal 200 and the antenna 130 of the mobile terminal 100.
For example, the control unit 350 controls the blower 310 based on a received signal level (for example, received signal strength or received signal-to-noise ratio) by contactless communication performed between the kiosk terminal 200 and the kiosk terminal 200. Further, the control unit 350 may control the blower 310 based on the positional relationship between the antenna 130 of the mobile terminal 100 and the antenna 230 of the kiosk terminal 200 detected from an image captured by the camera 330.

  Hereinafter, an example in which the blower 310 is controlled based on a received signal level by non-contact communication and an example in which the blower 310 is controlled based on an image taken by the camera 330 will be described in detail.

(Example of controlling the blower 310 based on the received signal level)
First, the example which controls the air blower 310 based on the received signal level by non-contact communication is demonstrated. Here, the received signal level by contactless communication refers to, for example, the received signal strength or received signal-to-noise ratio by contactless communication.

  When the user holds the mobile terminal 100 over the touch unit 220 of the kiosk terminal 200, the kiosk terminal 200 transmits a radio signal to the mobile terminal 100 by non-contact communication. At this time, the kiosk terminal 200 is fed back from the portable terminal 100, RSSI (Received Signal Strength Indicator) indicating the received signal strength by non-contact communication, or SNR (Signal to Noise) indicating the received signal-to-noise ratio by non-contact communication. Based on the information of (power Ratio), the positioning of the antenna is assisted by controlling the blower 310.

  Specifically, the antenna 130 of the mobile terminal 100 receives a wireless signal by non-contact communication transmitted from the antenna 230 of the kiosk terminal 200 and outputs the wireless signal to the receiving unit 160. The receiving unit 160 measures RSSI or SNR from the radio signal received by the antenna 130. Note that only one of RSSI and SNR may be measured. The transmission unit 150 of the mobile terminal 100 feeds back a signal obtained by performing processing such as encoding and modulation on the measured RSSI or SNR information to the kiosk terminal 200 via the antenna 130.

  Here, the above-described feedback may be performed using contactless communication used for content download. In addition, a wireless WAN (Wide Area Network) function represented by LTE (Long Term Evolution) and a wireless MAN (Metropolitan Area. Network) function represented by WiMAX (registered trademark) separately provided in the kiosk terminal 200 and the mobile terminal 100 are provided. , Such as a microwave using a wireless communication function such as a wireless LAN (Local Area Network) function represented by Wi-Fi (registered trademark) and a wireless PAN (Personal Area Network) function represented by Bluetooth (registered trademark) It may be performed at a different frequency.

  For example, the antenna 230 of the kiosk terminal 200 receives a wireless signal including RSSI or SNR information fed back from the mobile terminal 100 by non-contact communication and outputs the wireless signal to the receiving unit 260. The receiving unit 260 performs processing such as demodulation and decoding on the radio signal received by the antenna 230, restores RSSI or SNR information, and outputs the information to the control unit 350.

  The control unit 350 controls the strength of the wind output from the air outlet 315 of the blower 310 based on the RSSI or SNR information output from the reception unit 260, so that the kiosk terminal 200 and the mobile terminal 100 performed by the user are controlled. Assist with the alignment of each other's antennas. Specifically, the control unit 350 increases the strength of the wind output from the air outlet 315 of the blower 310 as the RSSI or SNR increases. On the other hand, the control unit 350 decreases the strength of the wind output from the air outlet 315 of the blower 310 as the RSSI or SNR is smaller. Note that the control unit 350 may perform control so that wind is not output from the air outlet 315 when the SNR is smaller than the required SNR value for communication without error.

  In this way, the control unit 350 increases the strength of the wind that is output as the RSSI or SNR fed back from the mobile terminal 100 increases, so that the user is stronger based on the wind strength received by the mobile terminal 100. The position where the portable terminal 100 is held can be moved to a position where the wind can be received. Here, the smaller the positional deviation between the antennas, the better the communication quality because the antenna 130 and the antenna 230 can communicate with each other with the beams facing each other. That is, RSSI and SNR increase. As a result, communication using a modulation scheme with higher transmission efficiency such as 16QAM (Quadrature Amplitude Modulation) or 64QAM becomes possible.

  The RSSI or SNR information fed back from the mobile terminal 100 has been described as an example of the received signal strength or the received signal-to-noise ratio by non-contact communication, but is not limited thereto. For example, the received signal strength or the received signal-to-noise ratio by contactless communication may be RSSI or SNR information measured from the radio signal received by the kiosk terminal 200 through the antenna 230. Further, the information is not limited to RSSI or SNR information but may be other information as long as the information corresponds to the received signal strength or the received signal-to-noise ratio by non-contact communication.

(Example of controlling the blower 310 based on an image taken by the camera 330)
Next, an example in which the blower 310 is controlled based on the positional relationship between the antenna 130 of the mobile terminal 100 and the antenna 230 of the kiosk terminal 200 detected from an image taken by the camera 330 will be described.

  The camera 330 captures the mobile terminal 100 held over the touch unit 220 of the kiosk terminal 200 and outputs the captured image to the control unit 350. Here, when the user holds the portable terminal 100 over the touch unit 220, the back surface of the portable terminal 100 is photographed by the camera 330 because the radiation direction of the radio wave from the antenna 130 faces the touch unit 220. Among the housings where the back surface of the mobile terminal 100 is covered, a member for transmitting millimeter-wave radio waves (where the antenna 130 is provided) A member having a high transmittance) is used (hereinafter, this position is referred to as a “window”).

  The control unit 350 detects the position of the above-described window portion in the image area of the image from the image captured by the camera 330. Here, the positional relationship between the image area photographed by the camera 330 and the position of the antenna 230 provided in the touch unit 220 of the kiosk terminal 200 can be uniquely determined because each position is fixed. Therefore, the control unit 350 can detect the positional relationship between the antenna 130 of the mobile terminal 100 and the antenna 230 of the kiosk terminal 200 detected from the image captured by the camera 330.

  Then, the control unit 350 determines the wind output from the air outlet 315 of the blower 310 based on the positional relationship between the antenna 130 of the mobile terminal 100 and the antenna 230 of the kiosk terminal 200 detected from the image taken by the camera 330. By controlling the strength, the positioning of the antennas of the kiosk terminal 200 and the portable terminal 100 is assisted. Specifically, the control unit 350 detects the positional relationship between the antenna 130 and the antenna 230 from the image output from the camera 330, and the wind output from the air outlet 315 of the blower 310 is smaller as the positional deviation between the antennas is smaller. Increase the strength of. On the other hand, the control unit 350 weakens the strength of the wind output from the blower opening 315 of the blower 310 as the position shift between the antennas increases.

  As described above, the control unit 350 increases the strength of the wind that is output as the positional deviation between the antennas is smaller. Therefore, the user receives the wind more strongly based on the strength of the wind received by the mobile terminal 100. The position where the portable terminal 100 is held can be moved to a position where the mobile terminal 100 can be held. Here, the smaller the positional deviation between the antennas, the better the communication quality because the antenna 130 and the antenna 230 can communicate with each other with the beams facing each other. That is, RSSI and SNR increase. As a result, communication using a modulation scheme with higher transmission efficiency such as 16QAM or 64QAM becomes possible.

  Note that when the control unit 350 detects the positional relationship between the antenna 130 of the mobile terminal 100 and the antenna 230 of the kiosk terminal 200 based on the image captured by the camera 330, the image captured by the camera 330 as described above. You may use methods other than the method of detecting based on the position of the window part detected from. For example, the control unit 350 recognizes the model of the mobile terminal 100, and determines the positional relationship between the antenna 130 of the kiosk terminal 200 and the position of the antenna 130 with respect to the recognized external shape of the model and the image captured by the camera 330. It may be detected. In this case, for example, by storing in the storage unit 320 and referring to information associated with the model information of a plurality of terminals that can communicate with the kiosk terminal 200 and the position information of the antenna in each terminal, The control unit 350 may specify the position of the antenna 130 with respect to the recognized external shape of the model. In addition, as a method for the control unit 350 to recognize the model of the mobile terminal 100, model information of the mobile terminal 100 (the mobile terminal 100 held over the touch unit 220) captured by the camera 330 is used using a wireless communication function. It is good also as a method of acquiring and recognizing the model of the portable terminal 100 based on the acquired model information. Here, the wireless communication function includes, for example, a wireless WAN function typified by LTE, a wireless MAN function typified by WiMAX (registered trademark), a wireless LAN function typified by Wi-Fi (registered trademark), and Bluetooth (registered). Any of a wireless PAN function represented by a trademark) may be used. In addition, as a method for the control unit 350 to recognize the model of the mobile terminal 100, each template image of a plurality of terminals that can communicate with the kiosk terminal 200 is stored, and template matching is performed with an image captured by the camera 330. Alternatively, a method of recognizing the model of the mobile terminal 100 may be used.

(Processing for assisting antenna alignment)
Next, with reference to FIG. 2, the operation of the antenna positioning assist processing in this embodiment will be described. FIG. 2 is a flowchart illustrating an example of an antenna alignment assist process in the present embodiment.

  First, when the user holds the portable terminal 100 over the touch unit 220 of the kiosk terminal in order to start downloading content from the kiosk terminal 200, the kiosk terminal 200 transmits a radio signal to the portable terminal 100 (step S10). ).

  When the mobile terminal 100 receives the radio signal transmitted from the kiosk terminal 200, the mobile terminal 100 measures RSSI or SNR (step S20). Next, the portable terminal 100 feeds back RSSI or SNR information to the kiosk terminal 200 (step S30).

  The control unit 350 of the kiosk terminal 200 determines the RSSI or SNR information fed back from the mobile terminal 100 or the positional relationship between the antennas of the kiosk terminal 200 and the mobile terminal 100 detected from the image captured by the camera 330. The strength of the wind output from the air outlet 315 of the blower 310 is determined. And the control part 350 controls the air blower 310 so that a wind is output from the ventilation port 315 with the determined wind intensity. Thereby, the air blower 310 outputs a wind from the blower opening 315 with the wind intensity determined by the control unit 350 (step S40).

  Based on the strength of the wind received by the mobile terminal 100, the user moves the position where the mobile terminal 100 is held over to a position where the wind can be received more strongly (step S50).

  Thereby, the positioning of the antennas of the kiosk terminal 200 and the mobile terminal 100 is performed, and the communication quality of content download from the kiosk terminal 200 to the mobile terminal 100 by non-contact communication is improved.

  Note that in the above-described processing, the antenna 310 is controlled by controlling the blower 310 based on both the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication and the image photographed by the camera 330. The positioning of the antenna may be assisted, or the positioning of the antenna may be assisted by controlling the blower 310 based on only one of them. In addition, when controlling the blower 310 based on both the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication and the image taken by the camera 330, one of them depends on the condition. As compared with the case where the blower 310 is controlled based only on this, it is possible to detect the positional deviation between the antennas with higher accuracy and assist the antenna alignment more appropriately. For example, since the positional relationship between the antennas may not be strictly known only with an image taken by the camera 330, the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication and the camera 330 may be determined. Controlling the blower 310 based on both of the images taken by the above may help the antenna alignment more appropriately.

  In the above-described processing, only the case of downloading from the kiosk terminal 200 has been described. However, even in the case of uploading to the kiosk terminal, the same configuration can be used. For example, in the case of upload, there is no need to feed back RSSI or SNR from the mobile terminal 100 to the kiosk terminal 200, the kiosk terminal 200 measures the RSSI or SNR of the radio signal transmitted from the mobile terminal 100, and the control unit 350 Can be output.

  As described above, the alignment assisting device 300 according to the present embodiment assists in the alignment of the antennas in the contactless communication between the kiosk terminal 200 (information terminal) and the mobile terminal 100. For example, the alignment assisting device 300 includes a notification unit that notifies the degree of positional deviation between the antennas of the kiosk terminal 200 and the mobile terminal 100, and a control unit 350. The control unit 350 receives the antenna 130 of the mobile terminal 100 detected from the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication or an image taken by the camera 330 included in the kiosk terminal 200. And the notification unit is controlled based on the positional relationship between the antenna 230 and the antenna 230 of the kiosk terminal 200.

  For example, the said notification part is the air blower 310 provided corresponding to the position where non-contact communication of the kiosk terminal 200 (information terminal) is performed. Then, the control unit 350 receives the received signal strength or received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication or the mobile terminal 100 detected from the image taken by the camera 330 included in the kiosk terminal 200. Based on the positional relationship between the antenna 130 and the antenna 230 of the kiosk terminal 200, the strength of the wind output from the blower 310 is controlled.

  As described above, the alignment assisting device 300 according to the present embodiment changes the strength of the wind output from the blower 310 according to the positional deviation of the antennas of the kiosk terminal 200 and the portable terminal 100, thereby It is possible to notify the user of the position where the portable terminal 100 is held so that the positional deviation of the mobile terminal 100 is reduced. Therefore, according to the present embodiment, in non-contact communication using a fixed beam directional antenna, when the user holds the portable terminal 100 over an information terminal (for example, the kiosk terminal 200) as a communication target, the mutual communication can be easily performed. Antenna positioning can be performed.

Therefore, the user can move the position where the portable terminal 100 is held to a position where the positional deviation between the antennas is reduced based on the strength of the wind received by the portable terminal 100.
In addition, since the radio waves are not visible, the user cannot normally know how fast communication is possible or how fast the transmission speed is. On the other hand, according to the present embodiment, the degree of positional deviation between the antennas (that is, communication quality and transmission speed) can be associated with the strength of the wind, so that the user grasps the communication status sensuously. It becomes possible to do.

  For example, the control unit 350 increases the received signal intensity or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication, or the mobile unit detected from the image captured by the camera 330 included in the kiosk terminal 200. Control is performed so that the strength of the wind output from the blower 310 increases as the positional deviation between the antenna 130 of the terminal 100 and the antenna 230 of the kiosk terminal 200 decreases. Thereby, the user can reduce the positional deviation between the antennas only by holding the portable terminal 100 over a position where the wind can be received more strongly. Therefore, according to the present embodiment, it is possible for a visually impaired person to perform antenna alignment.

  Note that the control unit 350 may control the air volume instead of the wind intensity output from the blower 310.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. Since the configuration of the contactless communication system 1 of the present embodiment is the same as that of the first embodiment, a characteristic process in the present embodiment will be described.

  The alignment assisting apparatus 300 according to the first embodiment described above is based on the magnitude of the RSSI or SNR, or the strength of the wind output from the blower 310 based on the positional relationship between the antennas detected from the image captured by the camera 330. By controlling the length (or the air volume), the user can grasp the communication status sensuously. On the other hand, in the alignment assisting apparatus 300 according to the present embodiment, wind is output from the blower 310 based on the magnitude of RSSI or SNR or the positional relationship between the antennas detected from the image captured by the camera 330. By controlling the frequency of transmission, it is possible for the user to grasp the communication status sensuously.

  A method for controlling the output frequency of wind will be described below. For example, the control unit 350 controls the blower 310 so as to repeat a short time wind output such as 0.1 second or 0.2 second at a predetermined time interval. At this time, the control unit 350 controls the wind to be output at shorter time intervals as the RSSI and SNR are larger, thereby increasing the wind output frequency. On the other hand, the control unit 350 controls the wind to be output at longer time intervals as the RSSI and SNR are smaller, thereby reducing the wind output frequency. In addition, the control unit 350 detects the positional relationship between the antenna 130 and the antenna 230 from the image captured by the camera 330, and controls so that the wind is output at a shorter time interval as the positional deviation between the antennas is smaller. Increase the wind output frequency. On the other hand, the control unit 350 performs control so that the wind is output at a longer time interval as the positional deviation between the antennas increases, thereby reducing the wind output frequency. The control unit 350 may perform control so that wind is not output from the air outlet 315 when the SNR is smaller than the required SNR value for communication without error.

  As described above, the alignment assisting device 300 in the present embodiment, like the first embodiment, notifies the degree of positional deviation between the antennas of the kiosk terminal 200 and the mobile terminal 100, and And a control unit 350.

  Here, the said notification part is the air blower 310 provided corresponding to the position where non-contact communication of the kiosk terminal 200 (information terminal) is performed. Then, the control unit 350 receives the received signal strength or received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication or the mobile terminal 100 detected from the image taken by the camera 330 included in the kiosk terminal 200. Based on the positional relationship between the antenna 130 and the antenna 230 of the kiosk terminal 200, the frequency at which wind is output from the blower 310 is controlled.

  As described above, the alignment assisting apparatus 300 according to the present embodiment changes the frequency of outputting the wind from the blower 310 according to the positional deviation of the antennas of the kiosk terminal 200 and the mobile terminal 100, thereby The user can be notified of the position where the portable terminal 100 is held over so that the positional deviation is reduced. Therefore, according to the present embodiment, in non-contact communication using a fixed beam directional antenna, when the user holds the portable terminal 100 over an information terminal (for example, the kiosk terminal 200) as a communication target, the mutual communication can be easily performed. Antenna positioning can be performed.

Therefore, the user can move the position where the portable terminal 100 is held to a position where the positional deviation between the antennas is reduced based on the frequency of wind received by the portable terminal 100.
In addition, since the radio waves are not visible, the user cannot normally know how fast communication is possible or how fast the transmission speed is. On the other hand, according to the present embodiment, the degree of misalignment (that is, communication quality and transmission speed) and the frequency of wind output can be associated with each other, so that the user can grasp the communication status intuitively. It becomes possible to do.

  For example, the antenna 130 of the mobile terminal 100 detected from the image captured by the camera 330 included in the kiosk terminal 200 as the received signal strength or received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication increases. As the positional deviation from the antenna 230 of the kiosk terminal 200 is smaller, the frequency of outputting wind from the blower 310 is controlled to be higher. As a result, the user can reduce the positional deviation between the antennas only by holding the portable terminal 100 over a position where the wind can be received more frequently.

<Third Embodiment>
Next, a third embodiment of the present invention will be described.
FIG. 3 is a configuration diagram illustrating an example of a schematic configuration of the contactless communication system 1a according to the present embodiment. The non-contact communication system 1a includes a mobile terminal 100 and a kiosk terminal 200a including the alignment assisting device 300a in the present embodiment. In FIG. 3, parts corresponding to those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

  The alignment assisting device 300 in the first embodiment and the second embodiment described above is based on the magnitude of RSSI or SNR, or the positional relationship between the antennas detected from images captured by the camera 330. By controlling the strength and output frequency of wind output from the user, the user can grasp the communication status sensuously. On the other hand, in the alignment assisting apparatus 300a in the present embodiment, the display 210 of the kiosk terminal 200a is based on the magnitude of RSSI or SNR or the positional relationship between the antennas detected from the image captured by the camera 330. In addition, by displaying a moving image representing the degree of positional deviation between the antennas (that is, communication quality and transmission speed), the user can easily grasp the communication status. Moreover, in the alignment assistance apparatus 300a in this embodiment, the user can easily grasp the communication status by displaying the direction in which the mobile terminal 100 should move in order to perform alignment. .

The alignment assisting device 300a in the present embodiment includes a storage unit 320, a camera 330, and a control unit 350a.
Based on the RSSI or SNR information output from the receiving unit 260 or the image output from the camera 330, the control unit 350a determines the degree of positional deviation between the antennas on the display 210 of the kiosk terminal 200a (ie, communication quality). By controlling the display of the moving image representing the transmission speed, the antenna positioning performed by the user is assisted.

  For example, the control unit 350a displays on the display 210 as the RSSI or SNR increases, or as the positional deviation detected from the positional relationship between the antenna 130 and the antenna 230 detected from the image captured by the camera 330 decreases. Control the video to play smoothly (smoothly).

  Specifically, the control unit 350a displays a moving image on the display 210, and the position detected from the positional relationship between the antenna 130 and the antenna 230 detected from the image photographed by the camera 330 as the RSSI or SNR increases. The smaller the deviation is, the faster the reproduction speed of the moving image displayed on the display 210 is. On the other hand, the controller 350a displays a moving image to be displayed on the display 210 as the RSSI or SNR is smaller or as the positional deviation detected from the positional relationship between the antenna 130 and the antenna 230 detected from the image taken by the camera 330 is larger. Slow down the playback speed.

  In addition, the control unit 350 may further display information indicating the direction in which the positional deviation is reduced on the display 210. The information indicating the direction in this case may be, for example, an arrow indicating the direction, a marker indicating the direction, or any display information.

  In addition, the function and operation | movement of the other structure (the memory | storage part 320, the camera 330) of the alignment assistance apparatus 300a are the same as that of 1st Embodiment.

  As described above, the alignment assisting device 300a in the present embodiment includes the notification unit that notifies the degree of positional deviation between the antennas of the kiosk terminal 200a (information terminal) and the mobile terminal 100, the control unit 350, However, the notification unit is a display 210 (display unit) of the kiosk terminal 200a, which is different from the alignment assisting apparatus 300 in the first embodiment and the second embodiment. The control unit 350 receives the antenna 130 of the mobile terminal 100 detected from the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication or the image taken by the camera 330 included in the kiosk terminal 200a. And the moving image displayed on the display 210 are controlled based on the positional relationship between the antenna 230 of the kiosk terminal 200a. For example, the control unit 350 controls the moving image playback speed.

  As described above, the alignment assisting device 300a according to the present embodiment controls the moving image displayed on the display 210 (for example, controls the reproduction speed) according to the positional deviation between the antennas of the kiosk terminal 200a and the portable terminal 100. Accordingly, it is possible to notify the user of the position where the portable terminal 100 is held over so that the positional deviation between the antennas is reduced. Therefore, according to the present embodiment, in non-contact communication using a fixed beam directional antenna, when the user holds the mobile terminal 100 over an information terminal (for example, the kiosk terminal 200a) to be communicated, Antenna positioning can be performed.

Therefore, the user can move the position where the portable terminal 100 is held to a position where the positional deviation between the antennas is reduced based on the playback speed of the moving image displayed on the kiosk terminal 200a. .
In addition, since the radio waves are not visible, the user cannot normally know how fast communication is possible or how fast the transmission speed is. On the other hand, according to the present embodiment, the degree of positional deviation between the antennas (that is, communication quality and transmission speed) can be associated with the playback speed of the moving image, so that the user can sensibly communicate the communication status. It becomes possible to grasp. That is, according to the present embodiment, the user can easily grasp the communication status by displaying the moving image representing the degree of positional deviation between the antennas (that is, communication quality and transmission speed) on the display 210. It becomes.

  For example, the controller 350 detects the kiosk terminal 200a detected by using the camera 330 included in the kiosk terminal 200a as the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication increases. Control is performed such that the smaller the positional deviation between the antenna 230 and the antenna 130 of the portable terminal 100 is, the faster the reproduction speed of the moving image displayed on the display 210 is. Thereby, the user can reduce the positional deviation between the antennas only by holding the portable terminal 100 over a position where the moving image reproduction speed becomes faster.

  Note that the controller 350a may change the number of playback frames (number of frames), the bit rate, etc. per short time instead of the playback speed. For example, as the RSSI or SNR is larger or the positional deviation detected from the positional relationship between the antenna 130 and the antenna 230 detected from the image taken by the camera 330 is smaller, the control unit 350a displays the moving image to be displayed on the display 210. The number of playback frames (number of frames) per short time may be increased, or the bit rate may be increased. On the other hand, the controller 350a displays a moving image to be displayed on the display 210 as the RSSI or SNR is smaller or as the positional deviation detected from the positional relationship between the antenna 130 and the antenna 230 detected from the image taken by the camera 330 is larger. The number of playback frames (number of frames) per short time may be reduced, or the bit rate may be lowered.

For example, the alignment assisting device 300 (300a) controls the notification unit (for example, the blower 310 or the display 210) based only on the received signal strength or the received signal-to-noise ratio (for example, RSSI or SNR) by non-contact communication. In such a case, an image obtained by photographing the mobile terminal 100 held over the touch unit 220 is unnecessary, and the camera 330 may not be provided.

  Moreover, in the said embodiment, although the memory | storage part 320 was provided in the kiosk terminal 200 (200a), the server apparatus different from the kiosk terminal 200 (200a) may be provided. For example, the control unit 350 refers to the information stored in the storage unit 320 by communicating with the storage unit 320 provided in the server device different from the kiosk terminal 200 (200a) via the communication network. Good.

  Moreover, although kiosk terminal 200 (200a) was demonstrated as an example as an information terminal which performs communication by non-contact communication, it is not restricted to kiosk terminal 200 (200a). For example, the information terminal that performs communication by non-contact communication may be a terminal other than the kiosk terminal 200 (200a), or may be a reader / writer having a function of reading or writing information of the mobile terminal 100. . On the other hand, although the smart phone was demonstrated as an example as the portable terminal 100 which performs communication by non-contact communication, it is not restricted to a smart phone. For example, the mobile terminal 100 may be a mobile phone, a tablet computer, a mobile game machine, a non-contact IC card, or the like.
