Reference numeral 101 denotes a terminal device having identification information, for example, a mobile terminal or an ID card. Reference numeral 102 denotes a content display control apparatus, which is, for example, a large television display. Reference numeral 103 denotes a content display unit. Reference numeral 104 denotes an identification information holding unit that holds identification information of the terminal device 101 (for example, an individual's name, membership number, and information that can specify a terminal). Reference numeral 105 denotes a communication unit inside the terminal apparatus 101 that performs communication between the terminal apparatus 101 and the content display control apparatus 102. Reference numeral 106 denotes a communication unit inside the content display control apparatus 102 that performs communication between the terminal apparatus 101 and the content display control apparatus 102. Reference numeral 107 denotes a selection detection unit that detects that content has been selected by the terminal device 101. An authentication unit 108 authenticates the selected content with the terminal device 101. Reference numeral 109 denotes a content display control unit that controls display of content. Reference numeral 110 denotes a holding unit that holds the content information of the content displayed on the display unit 103, the position information indicating the display position of the content, and the table shown in FIG. Reference numeral 111 denotes a determination unit that determines whether the displayed content has been changed.

  FIG. 6 shows a table held by the holding unit 110. The table includes, for each displayed content, a change flag indicating whether the display has been changed and identification information received from the terminal device that has changed the display. 6A is an example of a table in which the display is not changed for both contents A and B, and FIG. 6B is an example of a table in which the display of only content A is changed. Here, content A and content B are displayed on the display unit 103. The change flag is set to 1 when the display is changed, and is set to 0 when the display is not changed. The identification information is blank when the display is not changed, and the identification information of the changed terminal device is held when the display is changed.

  FIG. 2 is a flowchart of the content display control apparatus 102.

  In step S <b> 201, the selection detection unit 107 detects contact with content displayed on the display unit 103. When the terminal device 101 makes contact with the content displayed on the display unit 103, the selection detection unit 107 detects that there is a contact and the position of the contact. In the case of Yes in step S201, in step S202, the selection detection unit 107 specifies the selected content from the detected contact position and the position information held in the holding unit 110. The selection detection in step S201 and step S202 detects a contact and its position using a resistive touch panel.

  In step S203, the communication unit 106 requests identification information from the terminal device 101 that has detected contact in step S201. In step S <b> 204, the communication unit 106 receives identification information from the communication unit 105 of the terminal device 101, and the received identification information is input to the authentication unit 108. If the identification information cannot be received in step S204, the processing after step S205 is not performed. Means for performing communication in step S203 and step S204 include wireless communication of an IC card.

  In step S205, the determination unit 111 determines whether or not the content change flag specified in step S202 is 0 in the table held by the holding unit 110.

  When it is determined Yes in step S205, that is, when the content display is not changed, the display control unit 109 changes the content display in step S206. The changing method will be described later. In step S207, the holding unit 110 stores the identification information received in step S204 in the table to be held, and further sets the change flag to 1.

  When it is determined No in step S205, that is, when the display of content is changed, the authentication unit 108 authenticates the identification information in step S208. The authentication unit 108 determines whether the identification information associated with the content identified in step S202 in the table held in the holding unit 110 matches the identification information received in S204.

If it is determined Yes in step S208, the display control unit 109 returns to the original content (the content before being changed in step S206) based on the content information in the holding unit 110 and displays it in step S209. To do. In step S210, the holding unit 110 deletes the identification information associated with the content specified in step S202 from the held table, and further sets the change flag to 0.
Hereinafter, four methods for changing the display of content performed in step S206 will be described.

(1) Change method 1: Hide content In FIGS. 3A and 3B, the terminal device 101 comes into contact with the content 301 displayed on the display unit 103 of the content display control device 102 and the display is performed. It is a figure explaining the example in the case of changing. In FIG. 3A, the terminal device 101 contacts the displayed content 301, and thereafter, the content is hidden in FIG. 3B, and a dotted line indicating the position of the content is displayed. The dotted line is displayed so that the position where the non-displayed content is displayed can be specified. The dotted line, the solid line, or the four corners may be marked. In this process, in step S206, the display control unit 109 hides the content and displays the display position of the content based on the position information indicating the display position of the content in the holding unit 110.
FIGS. 3C and 3D are diagrams illustrating an example in which the terminal device 101 comes into contact with the non-displayed content 302 and the display is restored. FIG. 3C shows an example in which the terminal device 101 is in contact with an area where the content display position is displayed with a dotted line. Thereafter, in FIG. 3D, the original content is displayed. FIG. 3D shows a state after the processing corresponding to step S209 in FIG. 2 is performed.

(2) Change method 2: Change the viewing angle FIG. 4A shows the relationship between the person and the display from the front, and FIG. 4B shows the view from directly above. Here, it is assumed that the person A holds the changed terminal device. When the person A touches the content 402 on the table type display 401 with the terminal device, the viewing angle of the content is changed. At this time, the viewing angle is changed only in the direction of the person who contacts the terminal device 101, that is, in the direction in which the person A inside the 403 is present as shown in FIG. In this process, in step S206, the display control unit 109 controls the display angle from the content information stored in the holding unit 110 so that the content can be browsed only, and displays the content. As a result, as shown in FIG. 4C, when the person A brings the terminal device 101 into contact with the content 402, the content is visible to the person A even after the viewing angle is changed, but the person B views the content after the viewing angle is changed. Can no longer do.
Even when the person holding the changed terminal device moves, the display may be changed based on the movement. In that case, the relative positional relationship between the terminal device 101 and the selected content is detected using relative position detection means such as wireless communication, and the position of the person is periodically confirmed. FIG. 5 is an example when the person A moves. Assume that the person A moves as shown in FIG. 5A and the relative position between the person A and the content changes from 501 to 502. At this time, a change in the relative position is detected by wireless communication between the terminal device held by the person A and the display control unit 109, and the direction of the viewing angle is also changed by the same amount from 403 to 503. Then, as shown in FIG. 5B, the person A can browse the content in the same manner after moving, and the person B cannot be browsed.

(3) Change Method 3: Reduce Content When reducing the content, the display control unit 109 reduces the content from the content information stored in the holding unit 110 and displays the reduced content in step S206. FIG. 3E is a display example of reduced content.

(4) Change method 4: Set content resolution to low resolution When the content resolution is set to low resolution, the display control unit 109 sets the content resolution to low resolution from the content information stored in the holding unit 110 in step S206. And display low-resolution content. FIG. 3F is a display example of low-resolution content.
In the change methods 3 and 4, even a person who does not have a terminal device can see the content itself, but it is possible to make the content difficult to see by reducing or reducing the resolution. Therefore, it is desirable to set the reduction rate and the resolution level to levels that make it difficult to see the content.

  In the present embodiment, a change flag is held in the table, and it is determined by the change flag whether it has been changed. However, without holding the change flag in the table, step S205 may determine whether or not the change has been made based on whether or not the identification information is stored in the table. In that case, the size of the table to be held can be reduced. The table identification information is blank when the display has not been changed, but is not limited thereto, and a value of 0 may be entered.

  In the present embodiment, the content display control apparatus 102 includes the display unit 103, but the display unit 103 may be an external device.

  According to this embodiment, the display of the content displayed on the display unit can be changed by bringing a terminal device such as a portable terminal or an ID card close to a terminal device that can identify an individual and a terminal, and security can be given to the content at the same time. Further, the content is selected by contact with the terminal device, and the display of the content displayed on the display unit can be changed by an intuitive operation. Furthermore, since the change can only be canceled by the changed terminal device, a third party cannot release it without permission, and the security is also effective.
