Description

  The present invention relates to a content display device and the like.

  In recent years, devices that perform non-contact communication using a non-contact IC card such as NFC (Near Field Communication) are increasing. In order to perform such non-contact communication, not only a communication antenna but also a reader / writer device (hereinafter referred to as “RW device”) for acquiring radio waves from the other non-contact communication device and performing communication control is required. It becomes.

  Applications have been proposed in which data is transmitted and received between a content display terminal device and a user's information terminal device using these non-contact communication devices. For example, when an information terminal device touches an antenna installed beside an advertising display, the displayed advertisement is downloaded to the touched information terminal device (for example, Patent Document 1).

  On the other hand, the content display device has reached a large screen, and particularly in the case of a content display device for displaying an advertisement, a large screen display and a touch operation are possible to obtain feedback from the user. Some are.

  When these large-screen content display devices support non-contact communication, in many cases, an RW device is provided separately from the display device. However, in this case, it may be difficult for the user to know at what timing the touch should be performed, and there has been proposed an application in which non-contact communication is added to the display device as in the conventional example. In addition, as in the conventional example, a proposal has been made to provide a plurality of non-contact communication antennas on the display device in consideration of the enlargement of the screen of the display device.

Japanese Patent No. 3506939

  However, if a plurality of non-contact communication antennas and RW devices are provided on the content display device, the number of costs increases. In addition, it is necessary to secure a loading place for the RW device, which causes a problem in that it is a large constraint on the hardware design of the display device.

  Further, the power and communication control are complicated as many as provided. Usually, contactless communication is often required temporarily when acquiring data, and it is difficult to cost for temporary use.

  In addition, when viewed from the user, if a plurality of communication devices are merely arranged, it is not known which communication device should be touched, and the same operation is performed regardless of which communication device is touched. There was no point in changing the touch position.

  Conventionally, it is common to select content to be acquired in advance using a touch panel and then transfer content information to the information terminal device. For example, referring to FIG. 28, first, a required store is touched and selected from the floor map displayed on the display device (T1000).

  Next, the content (service) corresponding to the restaurant A that is touched is displayed on the screen. Among them, the user selects the necessary content (T1002). In order to transmit the selected content to the information terminal device, the user holds the information terminal device 1003 over the non-contact antenna (T1004).

  As a result, the desired content is transmitted to the information terminal device 3, but a plurality of operations are required, and it is not an intuitive operation, so it is not easy to use.

  In particular, in the case of a large-sized content display device installed in a shopping center or the like, users are used by a wide range of people such as children, adults, and elderly people. In such a case, it is not easy to use by requesting a plurality of operations.

  In particular, large-scale shopping centers in recent years have a large number of stores, and it is necessary to increase contents due to segmentation of user needs, and the tendency is remarkable.

  In order to solve the above-described problems, an object of the present invention is to use a plurality of non-contact communication antennas on a display device, and to perform intuitive operation by using content displayed by being assigned to the antennas. It is to provide a content display device or the like that can provide information related to the content to the user.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the present embodiment, as an example, the content display device according to the present invention will be described using an information display installed in, for example, a shopping mall as an example, but it is needless to say that the present invention can also be applied to other display devices.

[1. First Embodiment]
[1.1 Overall configuration]
First, the overall configuration of the first embodiment will be described with reference to FIG. FIG. 1 is a diagram showing a content display device 1. In the present embodiment, the apparatus is installed vertically (in a state where there are many vertical resolutions).

  Such a content display device 1 is installed to display various information in, for example, shopping malls, stations, event venues, and the like. For example, by displaying content received by communication, various information (contents) can be switched and displayed.

  Further, the information is devised so that the user can easily access it. For example, it is possible to display a two-dimensional code (QR code (registered trademark)) or to transmit content information by infrared rays.

  In the present embodiment, content information is transmitted to the user's information terminal device 3 using non-contact communication (NFC (Near Field Communication)), which is one of short-range wireless communications.

  When the user holds (touches) the information terminal device 3 over the content display device 1, communication is started by NFC. As a result, the designated content information is transferred to the information terminal device 3.

  Thus, in the present embodiment, a content transfer system including the content display device 1 and the information terminal device 3 will be described. A plurality of content display devices 1 / information terminal devices 3 may be provided. Further, another device as a content control device is connected to one or a plurality of content display devices 1, and the content control device may realize the following specific processing.

[1.2 Functional configuration]
Next, the functional configuration of the content display device 1 according to the present embodiment will be described with reference to FIG. As shown in FIG. 2, the content display device 1 includes a control unit 110, an NFC communication unit 120, an NW (Network) communication unit 130, a display unit 140, a touch detection unit 150, and a storage unit 160. Configured.

  The control unit 110 is a functional unit for controlling the entire content display device 1. The control unit 110 implements various functions by reading and executing various programs stored in the storage unit 160, and is configured by, for example, a CPU (Central Process Unit).

  The NFC communication unit 120 is a functional unit for performing non-contact communication. For example, communication is performed according to standards such as ISO / IEC 14443 and ISO / IEC 18092 (Felica (registered trademark)).

  Here, the NFC communication unit 120 will be described in detail with reference to FIG. The NFC communication unit 120 includes a non-contact antenna 1210, an antenna switching unit 1220, an antenna control unit 1230, and a non-contact communication unit 1240.

  Here, the non-contact antenna 1210 includes a plurality of antennas. For example, the first non-contact antenna 1210a, the second non-contact antenna 1210b,..., And the n-th non-contact antenna 1210n are provided.

  The plurality of non-contact antennas are connected to the antenna switching unit 1220. The antenna switching means 1220 switches available antennas. Further, this switching control is performed by the antenna control means 1230. In the present embodiment, since the NFC communication unit 120 is described as a module, the antenna control unit 1230 is provided, but the control unit 110 may perform this.

  The non-contact communication unit 1240 is a communication unit for the content display device 1 to perform non-contact communication (for example, NFC communication) with the information terminal device 3. Communication is performed with the NFC communication unit of the information terminal device 3 via a non-contact antenna. Here, in the present embodiment, the non-contact antenna 1210 is sequentially switched every predetermined time (for example, 10 ms). Note that the time for switching the non-contact antenna 1210 may be determined in advance or may be switched by setting. Moreover, it is good also as the setting (For example, a setting which lengthens an interval immediately after a store opening or just before a store closing, or shortens an interval on a holiday) according to the kind of content and time.

  As an example of communication, a case will be described in which the NFC communication unit 120 of the information terminal device 3 detects, for example, the second non-contact antenna 1210b. In this case, the antenna switching means 1220 fixes the antenna used for the second non-contact antenna 1210b. The non-contact communication unit 1240 communicates with the information terminal device 3 via the second non-contact antenna 1210b.

  The NW (Network) communication unit 130 is a functional unit for connecting to a network (for example, a wireless LAN, a 3G mobile communication network, or an LTE communication network) and communicating with other devices, servers, and the like. For example, the content is received via the NW communication unit 130.

  The display unit 140 is a display device for displaying various information. For example, it is configured by a liquid crystal display (LCD), an organic EL panel, or the like.

  The touch detection unit 150 is a functional unit for detecting a user's touch operation. As a method for detecting a touch, any method such as a resistive film method, an infrared method, an electromagnetic induction method, a capacitance method, or the like may be used. In general, the display unit 140 and the touch detection unit 150 are integrally formed and used as a touch panel.

  Here, the configuration of each apparatus will be described with reference to FIGS. 4 and 5. That is, the touch detection unit 150 is provided on the display panel of the display unit 140. Thereby, the touch input from the user can be detected.

  A non-contact antenna 1210 is disposed on the touch detection unit 150. As a result, the content is displayed on the display unit 140, and the user touches the information terminal device 3, thereby enabling communication using NFC.

  Note that the same effect can be obtained even if the non-contact antenna 1210 is arranged between the display unit 140 and the touch detection unit 150.

  As will be described later, a plurality of non-contact antennas 1210 are arranged on the display unit 140. Thereby, the non-contact antenna 1210 to be used is determined according to the content.

  The storage unit 160 is a functional unit that stores various programs and various data necessary for the operation of the content display device 1. The storage unit 160 includes, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The storage unit 160 stores content data 162, an antenna coordinate position table 164, and a transfer content information table 166. Here, an example of the content data 162 will be described with reference to FIG.

  As shown in FIG. 6, the content data 162 stores content information in a hierarchy of parent and child. For the parent content (for example, “A restaurant”), the content information of the child content (for example, child content A “reservation for store visit”, child content B “free drink ticket”, child content C “dessert free ticket”, child Content D “5% OFF coupon”) is stored.

  One or more pieces of content information of the child content are stored for the parent content. Further, although schematically shown in FIG. 6, each piece of content information stores content information associated with an appropriate service.

  For example, in the case of a service such as store reservation or reserved seat ticket purchase, a URL necessary for accessing the WEB site is included, or a signal for starting an application providing the service is included. good.

  In the settlement of electronic money, for example, electronic money stored in Felica (registered trademark) may be settled by cooperating with an electronic money application or the like. For coupons and the like, text information that functions as a coupon, for example, a service represented by ToruCa (registered trademark) may be used.

  Furthermore, the content information of the child content may include, for example, information such as a displayed figure, characters, and icons.

  The antenna coordinate position table 164 is a table that manages the antenna and the coordinates in the display unit 140 in association with each other. An example of the antenna coordinate position table 164 is shown in FIG. The antenna number is stored in association with the coordinates on the display unit 140.

  Here, as shown in FIG. 8, the coordinates store each antenna (1210a, 1210b, 1210c, 1210d, 1210e, 1210f) and the coordinates at which the antenna can be detected.

  The transfer content information table 166 is a table that stores each non-contact antenna and the corresponding content in association with each other. As shown in FIG. 9, the antenna number and the current content information are stored in association with each other.

  When the content information is “OFF”, the corresponding non-contact antenna is not used. In other words, the antenna switching unit 1220 performs the detection process while switching the non-contact antenna other than the content information “OFF”.

  Here, since it is only necessary to know the content information transferred to the information terminal device 3, the content information may be directly stored in the transfer content information table 166 or may be stored relatively. In the case of direct storage, the content information stored in the content data 162 is stored in the transfer content information table 166.

  When transferring (transmitting) content information to the information terminal device 3, the content information stored in the transfer content information table 166 is used.

  On the other hand, the relative position may be stored in the state shown in FIG. For example, when the information terminal device 3 is held over the antenna 4, the content information of “child content B” is transmitted according to FIG. 9. Therefore, referring to the content data 162 in FIG. 6, information on the child content B (for example, “free drink ticket”) in the current parent content (for example, “A restaurant”) is read and transmitted to the information terminal device 3.

[1.3 Process flow]
Next, the process flow in the first embodiment will be described. In the present embodiment, the main process is executed, and the NFC interrupt process of FIG. 11 is executed in a state where the information terminal device having the NFC function can communicate with the non-contact antenna, and the NFC detection process of FIG. Is executed.

[1.3.1 Main processing]
Next, the main processing of this embodiment will be described with reference to FIG. The main process of FIG. 10 is a process executed mainly in the present embodiment, and is a process executed when the information terminal device 3 or the like is not held over, for example.

  First, the parent content is displayed (step S102). Here, the parent content may be a WEB page or a document file. Further, it may be a media file such as an image file or a moving image file, or may be a text file.

  At this time, if a touch is detected from the user (step S104; Yes), the touched coordinates are detected. Then, the coordinate position is detected from the currently detected coordinates (step S106), and the selected parent content is identified (step S108).

  Subsequently, based on the selected parent content, child content information that is content information related to the child content is acquired (step S110). Based on the acquired child content information, the display of the child content and the transferred content information are updated (step S112).

  Specifically, a character, a figure, or the like indicating child content information is displayed at a position corresponding to the non-contact antenna. In addition, the transfer content information table 166 is updated. Here, specific content information may be stored in the transfer content information table 166, or the content information may be read with reference to the content data 162.

  Further, as described above, when content information is acquired at a relative position, it is natural that the transfer content information table 166 need not be updated. In this case, when transferring the content to the information terminal device 3, a plurality of tables are referred to.

[1.3.2 NFC interrupt processing]
Next, the NFC interrupt process will be described with reference to FIG. In the NFC interruption process, when the information terminal device 3 is held over, that is, when NFC communication is detected (step S122; Yes), the NFC detection process is executed (step S124). This process is a process that is always activated, and is executed when NFC communication is detected.

[1.3.3 NFC detection processing]
Next, the NFC detection process will be described with reference to FIG. First, the antenna number on which NFC communication has been performed is detected (step S152). Then, the content information corresponding to the detected antenna number (in this case, child content information) is acquired (step S154).

  Here, when content information exists (step S156; Yes), the acquired content information is transmitted to the information terminal device (step S158).

  As described above, according to the present embodiment, the child content as needed is displayed corresponding to the initial parent content. Then, the desired content information (child content information in the present embodiment) is transmitted to the information terminal device 3 simply by touching the display of the child content on the information terminal device 3.

  In this way, an intuitive operation of directly touching the displayed child content information with the information terminal device can be realized, and a user-friendly and highly convenient content display device is provided for many users. Is possible.

[1.4 Operation example]
An operation example of the present embodiment will be described with reference to the drawings. FIG. 13 is a diagram schematically showing a view in which the non-contact antenna 1210 is arranged on the display unit 140. For example, the first non-contact antenna 1210a as the antenna 1, the second non-contact antenna 1210b as the antenna 2, the third non-contact antenna 1210c as the antenna 3, the fourth non-contact antenna 1210d as the antenna 4, and the fifth non-contact antenna as the antenna 5. 1210e and the sixth non-contact antenna 1210f are arranged as the antenna 6.

  Then, the parent content is displayed in the area R102 of the display unit 140, and the child content is displayed in the NFC arrangement area R104. The child content is displayed superimposed on the NFC communication unit (antenna) corresponding to each content.

  For example, on the fifth non-contact antenna 1210e, a mark M102 that is a display indicating “dessert free ticket” is displayed. In this figure, the non-contact antenna 1210e is indicated by a dotted line for explanation, but in reality, the antenna is provided in a state that is difficult for the user to visually recognize.

  A mark M104 indicating a child content indicating “5% OFF coupon” is also displayed on the sixth non-contact antenna 1210f. The mark indicating the child content may be displayed superimposed on the antenna, or may be displayed in the antenna. That is, when the user holds the information terminal device 3, the guide display may be provided so as to come to a position where communication with the non-contact antenna is possible.

  In FIG. 13, when the information terminal device 3 is touched at the position of the fifth non-contact antenna 1210 e, the child content information of the dessert free ticket is transmitted to the information terminal device 3. In addition, nothing is executed even if the information terminal device 3 is touched at the position of the first non-contact antenna 1210a.

  FIG. 14 shows a state in which the parent content is switched. By switching the parent content, the display of the parent content is switched, and the display of the child content is also switched. For example, at this time, when the information terminal device 3 is touched at the position of the sixth non-contact antenna 1210f, the URL of the member registration WEB page is transmitted as the child content information. As a result, the user can easily perform member registration.

  As described above, according to the present embodiment, it is possible to realize the content display device 1 that can change the child content in accordance with the displayed parent content. The child content information is transmitted to the information terminal device 3 by holding (touching) the information terminal device 3 over the displayed child content.

  In addition, it is possible to change the number and position of antennas to be switched according to the currently selected content, and to perform a simple operation by showing the location of the antenna to be switched to the user. It can be so.

[2. Second Embodiment]
Next, the second embodiment will be described. In the present embodiment, the switching of the antenna of the content display device 1 is controlled. FIG. 15 is a process in which the NFC detection process of FIG. 12 in the first embodiment is replaced. Since other processes and functional configurations are the same as those in the first embodiment, description thereof is omitted.

  First, the antenna number on which NFC communication has been performed is detected (step S202). Subsequently, the content information of the detected antenna number is acquired (step S204). Here, if there is no content information for the antenna number (for example, “OFF”), no processing is performed (step S206; No).

  If content information is included, switching of antennas other than the detected antenna number is stopped (step S208). Specifically, the antenna switching unit 1220 connects the non-contact antenna having the currently detected antenna number to the non-contact communication unit 1240 according to the control command of the antenna control unit 1230. As a result, a plurality of pieces of child content information respectively assigned to a plurality of antennas can be prevented from being acquired simultaneously.

  Further, the display of other child contents is deleted (step S210). Thereby, the user can also visually recognize the child content currently acquired. Then, the related child content information is transmitted to the information terminal device 3 (step S212).

  An example of the operation is shown in FIG. FIG. 16 is a diagram illustrating a state in which the operation example of FIG. 13 is applied to the present embodiment. It is a figure of the state which became communicable by holding the information terminal device 3 over the 5th non-contact antenna 1210e. At this time, the child content “desert free ticket” is displayed as the mark M202.

  Compared to FIG. 13, FIG. 13 shows a display of child content on each non-contact antenna, whereas FIG. 16 shows a child content other than the non-contact antenna 1210e currently being communicated. Is no longer displayed.

  Thereby, the user does not select other child contents. Further, even if trying to communicate with another non-contact antenna, the antenna selected by the antenna switching means is only the fifth non-contact antenna 1210e, and therefore cannot communicate with another antenna.

[3. Third Embodiment]
Next, a third embodiment will be described. In the second embodiment, unselected child contents are hidden, but this embodiment is grayed out. FIG. 17 is a process in which the NFC detection process of FIG. 12 in the first embodiment is replaced. Since other processes and functional configurations are the same as those in the first embodiment, the description thereof is omitted.

  First, the antenna number on which NFC communication has been performed is detected (step S302). Subsequently, the content information of the detected antenna number is acquired (step S304). If there is no content information for the antenna number (for example, “OFF”), no processing is performed (step S306; No).

  If content information is included, switching of antennas other than the detected antenna number is stopped (step S308). Specifically, the antenna switching unit 1220 connects the non-contact antenna having the currently detected antenna number to the non-contact communication unit 1240 according to the control command of the antenna control unit 1230. As a result, a plurality of pieces of child content information respectively assigned to a plurality of antennas can be prevented from being acquired simultaneously.

  Further, the display is switched to a display incapable of acquiring other child content information (step S310). Thereby, the user can also visually recognize the content currently acquired. As the display indicating that acquisition is impossible, it is possible to gray out a mark indicating another content, change the color, or blink the mark.

  Conversely, special display such as changing the display color of the currently selected content, blinking display, changing brightness, etc. indicates that other content cannot be acquired relatively. Also good.

  Then, the child content information related to the selected child content is transmitted to the information terminal device 3 (step S312).

  An example of the operation is shown in FIG. FIG. 18 is a diagram showing a state in which the operation examples of FIGS. 13 and 16 are applied to this embodiment. It is a figure of the state which became communicable by holding the information terminal device 3 over the 5th non-contact antenna 1210e. At this time, the child content “desert free ticket” is displayed as the mark M302.

  Compared with FIG. 16, in FIG. 16, compared to the display of the child content other than the currently contacted fifth non-contact antenna 1210 e, the content other than the selected child content is not displayed in this embodiment. Is grayed out.

  Thereby, the user does not select other child contents. Further, even if trying to communicate with another non-contact antenna, the antenna selected by the antenna switching means is only the fifth non-contact antenna 1210e, and therefore cannot communicate with another antenna.

  Moreover, since it is not completely non-displayed, it can be considered when the user selects another child content again. For example, it is possible to consider a case where a free dessert ticket is acquired but a drink free ticket is selected again.

  In addition, when there are a plurality of users such as friends and family, when one person has acquired child content information, it is possible to consider the content that another user will select next.

[4. Fourth Embodiment]
Next, a fourth embodiment will be described. In the fourth embodiment, an embodiment in which contents are used hierarchically will be described.

  FIG. 19 is a diagram showing an example of the content data 162 in the present embodiment. In the present embodiment, grandchild content are included hierarchically. For example, as child content corresponding to the parent content “floor guide MAP”, there is information on each shop (for example, “site URL”). As another example, there are “A restaurant”, “B clothing store”, “C music store”, and “D coffee shop” as child content corresponding to the parent content “shop list”.

  Then, grandchild content (for example, “menu list”) is stored in correspondence with the child content “A restaurant” which is information of each shop serving as child content.

  FIG. 20 is a diagram showing an example of the transfer content information table 166 in the present embodiment. In this embodiment, it is described that the child content is displayed (assigned) at the position of the antenna “5” and the “grandchild” content is displayed at the position of the antenna “6”.

  FIG. 21 shows the main processing in this embodiment. The main process of FIG. 21 is a diagram replacing the main process of FIG. 10 in the first embodiment. Since other functional configurations and processes are the same as those in the first embodiment, description thereof will be omitted.

  Referring to FIG. 21, first, as shown in FIG. 19, a plurality of parent content candidates such as “floor guide MAP”, “shop list”, and “hotel” are displayed. When one parent content is selected by the user from the displayed parent content (step S402), the parent content is displayed, and child content information is acquired and the child content is displayed (step S404).

  In the child content display, for example, the child content corresponding to the parent content that does not have the grandchild content is determined to be the content to be transferred, and is updated as the transferred content.

  Subsequently, it is determined here whether or not the same parent content is selected again (step S406). Note that the content selection refers to detecting the touched position when, for example, the display screen is touched. Then, the content corresponding to the detected position is selected.

  In addition, since it suffices if the content is selected, for example, key input or voice input may be used. In addition, it may be recognized by a gesture, or may be detected and selected by a line-of-sight input or the like.

  Subsequently, when the same parent content is selected (step S406; Yes), the child content corresponding to the selected parent content is displayed (step S408). In the present embodiment, as an example, a list of selectable child contents is displayed based on the currently displayed parent contents.

  Subsequently, when one or a plurality of child contents are selected from the displayed child contents (step S410; Yes), the selected child contents are once displayed as selection candidates (step S412). Here, a plurality of child contents may be selected each time or may be selected collectively. Of course, it may be one.

  Then, when further selection is made from the displayed child contents of the selection candidates (step S414; Yes), the grandchild content corresponding to the child content is updated as the transfer content (step S416).

  In the present embodiment, the processing is described as sequential processing for convenience of description, but processing may be performed in parallel in the middle. For example, when another parent content is selected while the child content is displayed, the processing is executed again from step S404.

  Further, when the process returns in the middle, the child content selected as the selection candidate may be left as it is or may be cleared once. In the case as it is, it becomes possible to display a child content from a plurality of contents as a selection candidate. Also, once cleared, only the contents related to the currently displayed (selected) parent / child content are displayed, so that the display is intuitively easy for the user to understand.

  A specific operation will be described with reference to FIGS. FIG. 22 is a diagram showing a state in which the parent content is displayed in the region R402. In the area R404, different parent contents are displayed in a form different from that of the area R402, and “shop list”, “hotel”, and “museum” can be selected by touch.

  Furthermore, child content and grandchild content can be displayed at the non-contact antenna. In this figure, based on the parent content displayed in the region R402, one of the child contents is displayed as a mark M402 on the fifth non-contact antenna 1210e. That is, since the child content does not have grandchild content, it is displayed as it is (content is transferred).

  The sixth non-contact antenna 1210f is a place where grandchild content is scheduled to be displayed. Since no child content is currently selected, there is no corresponding grandchild content, and the mark M404 “Please select an image” is selected. Also, no marks are displayed for the first non-contact antenna 1210a, the second non-contact antenna 1210b, the third non-contact antenna 1210c, and the fourth non-contact antenna 1210d.

  In this state, by holding the information terminal device 3 over the fifth non-contact antenna 1210e, the NFC interruption process is executed, and the NFC detection process is continuously executed. Thereby, the content information of the child content is transferred to the information terminal device 3.

  Further, the content information is not transferred even if the information terminal device 3 is held over another non-contact antenna. In this case, for example, control may be performed so as not to switch to another non-contact antenna (an antenna on which no content is displayed) by an antenna control unit or an antenna switching unit.

  In FIG. 23, FIG. 23 shows a case where “shop list” which is the parent content is selected. In FIG. 23, an identification display of each shop is displayed in a region R410 as a child content corresponding to the shop list that is the parent content. For example, an icon L410 indicating A restaurant, L412 indicating B clothing store, L414 indicating C music store, and L416 indicating D coffee shop are displayed.

  Note that a stylized icon is used as the identification display, but it may be, for example, a character or a symbol, or a photograph.

  Here, when the D coffee shop is selected as a selection candidate, the icon of L416 is first dragged and dragged outside the region R410 to select L422 (FIG. 24). Subsequently, when selecting A restaurant, the icon of L410 is dragged and dragged outside the region R410 to be selected as a selection candidate (FIG. 25). In the case of this figure, L410 (L424) and L416 (L422) are selected as selection candidates.

  Here, there are two selection candidates. In this case, L422 is selected. For example, by selecting L422 as an example, a discount coupon image icon M406 is displayed as grandchild content corresponding to the child content “D coffee shop” in FIG. 19 (FIG. 26). Further, the non-contact antenna 1210f is also communicable.

  At this time, the grandchild content information is transferred by holding the information terminal device 3 over the sixth non-contact antenna 1210f (FIG. 27). Since the grandchild content is displayed on the display screen W410 of the information terminal device 3, it can be easily understood that the content has been transferred.

  The hierarchical contents are parent, child, and grandchild, but the hierarchy may be further increased. For example, the type of discount coupon may be displayed or the menu may be subdivided.
