In the present embodiment, as an example, the content providing system and the content display device according to the present invention will be described by taking an information display installed in a shopping mall or the like as an example, but of course, it can be applied to other display devices. Is.

[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 device is installed vertically (in a state where the resolution in the vertical direction is large).

Such a content display device 1 is installed for displaying various information in, for example, a shopping mall, a station, an event venue, or the like. For example, by displaying the content received by communication, various information (content) can be switched and displayed.

Furthermore, the information is devised so that it can be easily accessed by the user. For example, a device for displaying a QR code (registered trademark) or a device for transmitting content information by infrared rays can be considered.

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

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 transmitted to the information terminal device 3.

[1.2 Functional configuration]
Subsequently, the functional configuration of the content display device 1 in 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 communication unit 130, a display unit 140, a touch detection unit 150, and a storage unit 160. ing.

The control unit 110 is a functional unit for controlling the entire content display device 1. The control unit 110 realizes 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) or the like.

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 means 1220, an antenna control means 1230, and a non-contact communication means 1240.

Here, the non-contact antenna 1210 is composed of a plurality of antennas. For example, it has a first non-contact antenna 1210a, a second non-contact antenna 1210b, ..., An nth non-contact antenna 1210n.

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

The non-contact communication means 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 the non-contact antenna. Here, in the present embodiment, the non-contact antenna 1210 is sequentially switched at predetermined time (for example, 10 ms). The time for switching the non-contact antenna 1210 may be predetermined or may be switched depending on the setting. Further, it may be set to switch depending on the type of content and the time (for example, the interval may be lengthened immediately after the store opens or just before the store closes, or the interval may be shortened on holidays).

As an example of communication, a case where the NFC communication unit of the information terminal device 3 is detected by, for example, the second non-contact antenna 1210b will be described. In this case, the antenna switching means 1220 fixes the antenna used for the second non-contact antenna 1210b. Then, the non-contact communication means 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, 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 types of information. For example, it is composed of a liquid crystal display (LCD), an organic EL panel, and the like.

The touch detection unit 150 is a functional unit for detecting a user's touch operation. As the method for detecting the 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. Further, it is common that the display unit 140 and the touch detection unit 150 are integrally formed and used as a touch panel.

Here, the configuration of each device 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. As a result, the touch input from the user can be detected.

Further, the non-contact antenna 1210 is arranged on the touch detection unit 150. As a result, the content is displayed on the display unit 140, and when the user touches the information terminal device 3, communication using NFC becomes possible.

The same effect can be obtained by arranging the non-contact antenna 1210 between the display unit 140 and the touch detection unit 150. That is, the non-contact antenna 1210 is arranged on the same surface side as the display unit 140.

Further, a plurality of non-contact antennas 1210 are arranged on the display unit 140. As a result, 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 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

Further, the storage unit 160 stores the content data 162 and the antenna information 164.

The content data stores information about the content to be displayed on the display unit 140. For example, a still image to be displayed or a moving image is stored. Further, additional information corresponding to the content is stored.

Here, the additional information is information transmitted to the information terminal device 3 via the NFC communication unit 120. For example, it may be URL information indicating information related to the content, discount information, or information such as an image. The user can acquire additional information by touching the NFC communication unit 120 (nth non-contact antenna 1210n) of the content display device 1 with the information terminal device 3.

The antenna information 164 stores information about the non-contact antenna. For example, it stores where the non-contact antenna is located at the coordinates of the display screen displayed on the display unit 140. For example, FIG. 6 illustrates the relationship between the display coordinates and the coordinates where the non-contact antenna is located.

For example, in the (0,0)-(Xmax, Ymax) coordinate system, the non-contact antenna A1 is located at (Xa1, Ya1)-(Xa2, Ya2). For example, at this time, it is assumed that the content C1 is displayed in (X1, Y1)-(X2, Y2). In this case, it can be determined that the content C1 is displayed on the non-contact antenna A1. It can also be determined that it is the content C1 that is displayed correspondingly on the non-contact antenna A1. In this way, the correspondence between the non-contact antenna and the content is determined from the coordinates with the non-contact antenna and the coordinates on which the content is displayed.

[1.3 Processing flow]
Next, the flow of processing in the first embodiment will be described.

First, the main processing of the present embodiment will be described with reference to FIG. 7. First, the content having the additional information is displayed on the display unit 140 (step S102).

Here, the information terminal device 3 is detected by any of the non-contact antennas (step S104; Yes). At this time, the coordinates at which the content (content having additional information) is currently displayed are acquired (step S106).

The communication antenna is specified from the acquired coordinates (step S108). Specifically, the non-contact antenna included in the coordinates of the displayed content is read out from the antenna information 164 and specified as a communication antenna.

Subsequently, the specified communication antenna (non-contact antenna) is enabled (step S110), and when NFC communication is detected, NFC communication processing is executed (step S112; Yes → step S114). That is, by executing NFC communication, additional information of the displayed content is transmitted to the information terminal device 3.

[1.4 Example]
Examples of this embodiment will be described with reference to the drawings. FIG. 8 is a diagram schematically showing a diagram in which the non-contact antenna 1210 is arranged on the display unit 140. For example, the first non-contact antenna 1210a is arranged as the non-contact antenna A1.

Further, the content C100 is displayed on the display screen W100 of FIG. The content C100 is displayed on the non-contact antenna A7. Therefore, of the plurality of non-contact antennas, only the non-contact antenna A7 is “ON” (specified as a communication antenna). That is, it is not necessary to turn on all the non-contact antennas, and even if the information terminal device 3 touches a touch other than the non-contact antenna A7, nothing is executed.

As described above, according to the present embodiment, it is possible to realize the content display device 1 capable of changing the touch position according to the position of the displayed content.

According to the present embodiment, by selecting an effective non-contact antenna from a plurality of non-contact antennas, only one non-contact communication unit can perform non-contact communication. As a result, for example, as an example of the non-contact communication unit, the number of IC card transmitters / receivers mounted can be reduced, and the effect of cost reduction can be expected.

In addition, it is possible to change the number and position of the antennas to be switched according to the currently selected content, and the position of the currently selectable non-contact antenna is displayed to the user by displaying the content. It will be. Therefore, the user should be able to perform natural operations.

[2. Second Embodiment]
Next, the second embodiment will be described. The second embodiment is an embodiment for explaining the relationship between the content and the non-contact antenna.

That is, in the first embodiment, the non-contact antenna at the position included in the displayed content is described as effective, but for example, when the non-contact antenna is not completely included, the non-contact antenna is in contact with the display area of the content. In this embodiment, the closest non-contact antenna or the non-contact antenna having the largest superimposed area is specified as a communication antenna.

FIG. 9 is an embodiment in which the content C200 is displayed on the display screen W200 in the present embodiment. In this case, there is no non-contact antenna completely included in the display area of the content C200.

Therefore, the non-contact antenna A7, which is a non-contact antenna in contact with the content or a non-contact antenna having the most overlapping regions, is specified as a communication antenna for communication (step S108 in FIG. 7).

As described above, according to the present embodiment, even if the content does not completely include the non-contact antenna, the non-contact antenna in the vicinity of the content can be specified and used as a communication antenna.

Such an embodiment is particularly effective when the content C200 is arbitrarily moved by the user and is displaced from the position where the non-contact antenna is arranged.

[3. Third Embodiment]
Next, the third embodiment will be described. The third embodiment is an embodiment selected according to a predetermined rule when there are a plurality of identifiable non-contact antennas.

For example, when there are a plurality of non-contact antennas in the vicinity of the displayed content, the non-contact antenna on the right side of the displayed content is selected.

FIG. 10 is an embodiment in which the content C300 is displayed on the display screen W300 in the present embodiment. In this case, there are a plurality of non-contact antennas, but in the present embodiment, the non-contact antenna A9 located on the right side is specified and used as a communication antenna.

In this way, when the content is displayed, the non-contact antenna in a predetermined direction may be selected and used. This is because, for example, when the identification display C310 called "touch" is displayed as shown in FIG. 10, the user tends to touch the right side. Therefore, it is effective to preferentially select the non-contact antenna on the right side.

[4. Fourth Embodiment]
Next, the fourth embodiment will be described. The fourth embodiment is an embodiment in which identification display based on additional information is performed on the content (content identification information is displayed).

The flow of processing in this embodiment is shown in FIG. The processing flow of FIG. 11 replaces the processing flow of FIG. 7 described in the first embodiment, and the same processing is designated by the same reference numerals and the description thereof will be omitted.

That is, in FIG. 11, after displaying the content (step S102), identification display based on additional information is performed on the content display (step S202). For example, the user can recognize that additional information of the URL is transmitted, coupon information is transmitted, and image / music data is transmitted by the identification display.

[5. Fifth Embodiment]
Next, the fifth embodiment will be described. The fifth embodiment is an embodiment in which a communication antenna (non-contact antenna) is identified and displayed (communication antenna identification information is displayed) in order to guide the user where to touch.

The flow of processing in this embodiment is shown in FIG. The processing flow of FIG. 12 replaces the processing flow of FIG. 7 described in the first embodiment, and the same processing is designated by the same reference numerals and the description thereof will be omitted.

That is, after the communication antenna is enabled (step S110), the communication antenna is identified and displayed (step S302). This makes it clear where the user should touch.

For example, on the display screen W500 of FIG. 13, the content C500 is displayed at the position of the non-contact antenna A7. Here, the identification display R500 is performed at a communicable position so that the user can visually recognize the non-contact antenna A7. The user can acquire additional information by touching the position of the identification display R500.

In addition, like the content C510, "touch!" May be clearly displayed. As a result, the user can visually recognize the position to be touched more clearly. The content C510 may be displayed at the position of the non-contact antenna. As a result, the user only has to touch the display "touch!", And the user can perform an intuitive operation.

Here, the identification display may be different depending on the type of additional information. For example, as additional information, the identification display may be displayed in a red frame in the case of an image, and the identification display may be displayed in a blue frame in the case of a WEB page (URL).

[6. 6th Embodiment]
Next, the sixth embodiment will be described. A sixth embodiment is an embodiment in which the touch panel function is turned off (that is, the operation by the touch panel is invalidated) when non-contact communication is performed.

The flow of processing in this embodiment is shown in FIG. The processing flow of FIG. 14 replaces the processing flow of FIG. 7 described in the first embodiment, and the same processing is designated by the same reference numerals and the description thereof will be omitted.

That is, after the communication antenna is enabled (step S110), the touch panel is disabled (step S402).

Here, if NFC communication is detected, NFC communication processing is executed (step S112; Yes → step S114), and the touch panel is enabled after the NFC communication is completed (step S406).

On the other hand, even if the touch panel is disabled, if the NFC communication is not started until a predetermined time elapses, the touch panel is enabled again (step S112; No → step S404; Yes → step S406).

As described above, according to the present embodiment, the touch panel becomes invalid when the non-contact communication (NFC communication) is started. Therefore, there is no malfunction due to finger touch detection when performing non-contact communication.

In step S402, the range for disabling the touch panel may be limited to the vicinity of the communication antenna. That is, although the touch panel as a whole can be operated, it is possible to prevent a malfunction due to finger touch detection during non-contact communication.

[7. Seventh Embodiment]
Next, the seventh embodiment will be described. The seventh embodiment is an embodiment when a plurality of non-contact antennas are used.

For example, FIG. 15 is a diagram showing an example of the display screen W700. The content C700 is displayed on the display screen W700, and the content C700 is displayed so as to overlap the non-contact antenna A7 and the non-contact antenna A10.

In this case, the non-contact antenna is switched and operated by the control of the antenna control means 1230. That is, the non-contact antenna A7 and the non-contact antenna A10 can communicate with each other at predetermined time intervals.

Here, when the information terminal device 3 is detected, the non-contact antenna detected by the antenna control means 1230 is identified as a communication antenna and activated. That is, as a user, additional information can be acquired by either the non-contact antenna A7 or the non-contact antenna A10.

[8. 8th Embodiment]
Next, the eighth embodiment will be described. The eighth embodiment is an embodiment in which the content is displayed at a position where the non-contact antenna is located.

For example, when displaying the content, the content display process of FIG. 16 is executed. First, the display position of the content is determined (step S502). Here, it is determined whether or not the non-contact antenna is included in the displayed content (step S504).

When the non-contact antenna is not included in the displayed content, the display position of the content is adjusted to the position where the non-contact antenna is included (step S504; Yes → step S506).

According to the present embodiment, when the content is displayed, if the position of the non-contact antenna is deviated, the display position of the content can be adjusted. As a result, for example, even if the content display device 1 has different antenna arrangements, it is possible to appropriately display the content.

It is also possible to automatically move the content when the user moves the content. For example, FIG. 17A is a diagram showing an example of a display screen W800 on which the content C800 is displayed.

The content C800 is content arranged by the user. In this case, the content C800 is displayed at a position deviated from the position of the non-contact antenna A7. Therefore, the content C800 is automatically moved in the direction S1.

Then, as shown in FIG. 17B, the content C800 is automatically displayed at the position of the non-contact antenna A7. At this time, the content may be moved from the position where the content is displayed so as to include the nearest antenna, or may be moved to a position where the content does not overlap with other content.

[9. 9th Embodiment]
Next, the ninth embodiment will be described. The ninth embodiment is an embodiment in which the relationship between the position of the non-contact antenna and the type / content of the additional information is managed in advance, and the content is displayed according to the type / content of the additional information.

For example, it is assumed that the non-contact antenna 10 is managed in association with "coupon information" and the non-contact antenna 12 is associated with "WEB site". In this case, the position of the displayed content is also determined according to the additional information of the displayed content.

Further, when the content type is "children's content", it is assigned to the antenna arranged in the lower row, and in the case of "adult content", it is assigned to the antenna arranged in the middle row.

In this case, it is possible to automatically determine at which position the content is displayed according to the content of the content.
