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) and the mobile terminal 100 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. 5A, 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. 5B 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. 6 shows an example in which a terminal installation guide 621 indicating a position when the mobile terminal 100 is installed is provided on the touch unit 620 of the kiosk terminal 600. In addition, FIG.6 (b) is the figure which expanded and showed the touch part 620 of the kiosk terminal 600 shown to Fig.6 (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.

<First Embodiment>
FIG. 1 is a configuration diagram illustrating an example of a schematic configuration of a kiosk terminal 200 including the alignment assisting device 300 according to the first embodiment of the present invention.
Although not shown in FIG. 1, it is assumed that a terminal that performs non-contact communication with the kiosk terminal 200 is the same as the portable terminal 100 shown in FIG. The mobile terminal 100 is, for example, a smartphone, and includes an antenna 130 that is a fixed beam directional antenna for transmitting and receiving data to and from the kiosk terminal 200.

  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. In the following, antenna positioning assistance processing in the case of downloading from the kiosk terminal 200 will be described. However, even in the case of uploading to the kiosk terminal 200, between the kiosk terminal 200 and the mobile terminal 100 by non-contact communication It can be applied by switching data transmission and reception.

A kiosk terminal 200 illustrated in FIG. 1A includes a display 210, a touch unit 220, an antenna 230, a display unit 240, a transmission unit 250, a reception unit 260, a switching unit 270, and an alignment assisting device 300. And.
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, and the generated transmission The 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.

  The display unit 240 is provided on the surface of the touch unit 220 on which the user holds the portable terminal 100 when performing non-contact communication. That is, the display unit 240 is provided at a position corresponding to the position where the non-contact communication with the mobile terminal 100 is performed in the kiosk terminal 200. The display unit 240 displays an image under the control of the alignment assisting device 300. FIG. 1B is a diagram illustrating a display surface of the display unit 240 provided in the touch unit 220. For example, the display unit 240 displays an image of the portable terminal 100 (an image indicated by reference numeral 410) under the control of the alignment assisting device 300.

For example, the recognition unit 310 recognizes the model of the mobile terminal 100 using the following recognition method or the like.

  For example, when the user approaches the kiosk terminal 200, a wireless WAN (Wide Area Network) function represented by LTE (Long Term Evolution), a wireless MAN (Metropolitan Area. Network) function represented by WiMAX (registered trademark), Wi -Perform non-contact communication using wireless communication functions such as a wireless LAN (Local Area Network) function represented by Fi (registered trademark) and a wireless PAN (Personal Area Network) function represented by Bluetooth (registered trademark). Before, the model information of the portable terminal 100 is transmitted to the kiosk terminal 200. Thereby, the recognition unit 310 of the kiosk terminal 200 acquires the model information transmitted from the mobile terminal 100 and recognizes the model of the mobile terminal 100 based on the acquired model information.

  It should be noted that the camera 310 (not shown) provided in the kiosk terminal 200 is used to photograph the mobile terminal 100 held by the user with respect to the touch unit 220 of the kiosk terminal 200, and based on the photographed image, the recognition unit 310 You may recognize the model of the portable terminal 100. FIG. For example, the alignment assisting apparatus 300 manages matching data in which model information of a plurality of terminals that can communicate with the kiosk terminal 200 and template images of each model are associated with each other. Template matching between each template image and an image obtained by photographing the mobile terminal 100 may be performed to recognize the model of the mobile terminal 100.

  For example, the recognition unit 310 may display a list of models of a plurality of terminals that can communicate with the kiosk terminal 200 on the display 210 so that the user can select and input the model of the mobile terminal 100. . Then, the recognition unit 310 may specify the model selected by the user from the model list as the model of the mobile terminal 100. In this case, the recognizing unit 310 displays the model candidates of the portable terminal 100 recognized based on the image photographed by the camera (not shown) of the kiosk terminal 200 on the display 210 as the above-described model list. The user may be able to select and input. Instead of displaying the model list on the display 210, the model list may be displayed on the display unit of the mobile terminal 100 by transmitting the model list to the mobile terminal 100. Then, the user may be able to select and input from the model list displayed on the mobile terminal 100. In this case, information indicating the model selected by the user may be transmitted from the mobile terminal 100 to the kiosk terminal 200, and the recognition unit 310 may specify the model selected by the user as the model of the mobile terminal 100.

  Thus, the recognition unit 310 can recognize the model of the mobile terminal 100 using the above-described recognition method or the like. Then, the recognition unit 310 recognizes the model of the mobile terminal 100 and then outputs the recognized model information to the extraction unit 330.

Is managing. For example, information of the terminal structure DB 321 is stored in the storage unit 320.

  When acquiring the model information of the mobile terminal 100 output from the recognition unit 310, the extraction unit 330 extracts the position information of the antenna of the mobile terminal 100 registered in the terminal structure DB 321 based on the acquired model information. Here, as shown in FIG. 2A, the position information of the antenna 130 of the portable terminal 100 is, for example, from one end of the back surface of the portable terminal 100 (the left end in this figure, the end indicated by the symbol L1) to the portable terminal. 100 means the distance W to the center of the antenna 130 and the distance T from the one end of the back surface of the portable terminal (the upper end in FIG. 1 to the end indicated by the symbol L2) to the center of the antenna 130. Further, the extraction unit 330 outputs the model information of the mobile terminal 100 (model information recognized by the recognition unit 310) and the extracted position information to the display control unit 340.

  Here, the back surface of the mobile terminal 100 is a surface opposite to a surface on which information is displayed or operated (hereinafter referred to as “front surface”) when the user uses the mobile terminal 100. The beam from the antenna 130 is emitted through the back side.

  When the display control unit 340 acquires the model information and the position information output from the extraction unit 330, the display control unit 340 displays an image of the surface of the mobile terminal 100 (reference code) indicated by the acquired model information based on the acquired model information and position information. 410) is displayed on the display unit 240 provided in the touch unit 220 of the kiosk terminal 200. At this time, as shown in FIG. 2B, the display control unit 340 displays the image of the surface of the mobile terminal 100 (the image indicated by reference numeral 410), the position of the antenna 130 of the mobile terminal 100 on the image, and the kiosk. The position of the antenna 230 of the terminal 200 is displayed on the display unit 240 so as to coincide with the display surface of the display unit 240 in the vertical direction. Specifically, the display control unit 340 is located at the position indicated by the reference symbol L1 of the mobile terminal 100 on the image at a position W in the right direction from the center of the antenna 230 of the kiosk terminal 200, and The image of the surface of the mobile terminal 100 is displayed so that the end portion indicated by the symbol L2 of the mobile terminal 100 on the image is positioned at a distance T from the center upward.

  Note that the image of the surface of the mobile terminal 100 that the display control unit 340 displays on the display unit 240 is stored in the storage unit 320. For example, the image of the surface of the mobile terminal 100 is stored in the terminal structure DB 321 in association with the model information.

  As described above, the alignment assisting device 300 causes the display unit 240 to display an image of the mobile terminal 100 such that the position of the antenna 230 of the kiosk terminal 200 and the position of the antenna 130 of the mobile terminal 100 match each other. It is possible to notify the user of the position where the portable terminal 100 is held over so that the positional deviation of the antenna becomes small. Therefore, the user can easily adjust the position of the antenna 130 of the mobile terminal 100 to the position of the antenna 230 of the kiosk terminal 200 simply by holding the mobile terminal 100 so as to overlap the image of the mobile terminal 100 displayed on the display unit 240. be able to.

  Projection unit 350 is not limited to a laser projector using a laser, and may be, for example, a projector that projects an image displayed on a display, a slide projector that projects a slide, or an overhead projector.

  Moreover, the projection part 350 should just project the information based on the shape of the portable terminal 100, and is not restricted to projecting the shape of the portable terminal 100. FIG. For example, as information based on the shape of the mobile terminal 100, a part of the shape (for example, only information indicating the positions of the four corners of the mobile terminal 100) may be projected, or an image of the surface of the mobile terminal 100 is projected. May be.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and includes a design and the like within a scope not departing from the gist of the present invention. For example, the configurations described in the first embodiment and the second embodiment described above can be arbitrarily combined.

  In the above embodiment, the example in which the terminal structure DB 321 is stored in the storage unit 320 of the kiosk terminal 200 (200a) has been described. However, the terminal structure DB 321 may be provided in a server device different from the kiosk terminal 200 (200a). For example, the extraction unit 330 and the display control unit 340 communicate with the terminal structure DB 321 provided in a server device different from the kiosk terminal 200 (200a) via the communication network, thereby registering information registered in the terminal structure DB 321. May be used.

  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.

  Note that the recognition unit 310, the extraction unit 330, or the display control unit 340 in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. You may implement | achieve using programmable logic devices, such as FPGA (Field Programmable Gate Array).
