The contents of the table may be updated when, for example, a device is added or deleted.

  As described above, in the device linkage system according to the first embodiment, the electronic tag reader is provided in the display device, and the electronic tag embedded in the device is read to determine whether the device can be linked. Therefore, the display device functions as an interface that combines input / output functions of a plurality of electronic devices, and can integrate and link input / outputs of various electronic devices.

  FIG. 7 is a configuration diagram of the display device and the device linkage system according to the second embodiment. A display device 10a illustrated in FIG. 7 is a portable device, and includes a display unit 11, a control unit 12a, a device information acquisition unit 13, a server communication unit 14, an icon storage unit 15, and a touch panel 16. In addition, the display device 10 a is connected to the digital camera 21, the television 22, the speaker 23, and the server 20. In the configuration shown in FIG. 7, the same components as those in FIG.

  The touch panel 16 is a panel provided to overlap the display unit 11 and is an input unit that detects contact with the panel. Information on the position of contact with the panel is input to the control unit 12a. The control unit 12a processes the input by associating the information on the position of contact with the panel with the display content of the display unit 11.

  For example, when an icon is being displayed at a position where contact is detected on the touch panel 16, the control unit 12a recognizes the detected contact as a selection operation for selecting the icon displayed at the corresponding position. When the contact position moves after the selection operation, the control unit 12a recognizes it as a movement operation for moving the display position of the selected icon.

  In addition, the control unit 12 a stores icon information in the icon storage unit 15 when the device information acquisition unit 13 acquires device information. The device ID, input port address, and output port address are stored in the icon storage unit 15 in association with icon information. The accumulated icons can be displayed on the display unit 11 regardless of the state of the corresponding device and the power on / off of the corresponding device.

  When a moving operation is performed on the displayed icon and another icon is displayed at the destination, the control unit 12a corresponds to the device corresponding to the icon that is the target of the moving operation and the destination icon. This is recognized as a linkage operation that instructs linkage with a device.

  When recognizing the linkage operation, the control unit 12a outputs device information to the server communication unit 14 to determine whether or not linkage is possible.

  FIG. 8 is an explanatory diagram of the internal configuration of the display device, the information device, and the server. The control unit 12a includes an icon control unit 12b and a tag analysis unit 12c therein.

  The control unit 52 is a control unit that controls the entire information device 50, and is connected to the server communication unit 55, the output unit 53, and the input unit 54. If the control unit 52 and the device information transmission unit 51 are connected, the control unit 52 can rewrite the device information. If rewriting of the device information by the control unit 52 is not necessary, the control unit 52 and the device information transmission unit 51 may not be connected.

  The server communication unit 55 communicates with the server 20 and receives information on the device to be linked. Therefore, the output unit 53 and the input unit 54 can be used for input / output of other linked information devices in addition to input / output to the information device 50.

  The server 20 includes a device information transmission unit 61, a control unit 62, a communication unit 63, a user data storage unit 64, and an input / output combination table 65 therein. The device information transmission unit 61 holds device information of the server 20. The device information held by the device information transmission unit 61 is read by the device information acquisition unit 13 when the display device 10 a approaches the server 20. When the server 20 and other devices are not linked, the device information transmission unit 61 need not be provided.

  The control unit 62 is a control unit that controls the entire server 20. The communication unit 63 communicates with the server communication unit 14 included in the display device 10a and the server communication unit 55 included in the information device 50. The input / output combination table 65 is a table that indicates combinations of input / output of devices, that is, whether or not devices can be linked. The user data storage unit 64 is a storage unit in which a user can store arbitrary information.

  FIG. 9 is a flowchart showing the processing operation of the device linkage system shown in FIG. When the display device 10a approaches another device, the device information acquisition unit 13 receives the device information (S201, Yes). When the device information acquisition unit 13 receives the device information, the control unit 12a displays an icon on the display unit 11 (S202).

  When the device information is not received (S201, No), or after displaying the icon (S202), the control unit 12a monitors the operation on the icon. If no operation on the icon is detected (S203, No), the process returns to step S201 again.

  When an operation on the icon is detected (S203, Yes), the control unit 12a controls the icon based on the detected operation (S204). As a result, if the controlled icon overlaps with another icon (S205, Yes), whether the server 20 can operate in cooperation with the two devices, that is, whether the two devices can operate in combination. Is determined (S206).

  If the two devices cannot be combined (S207, No), or if the icons do not overlap as a result of icon control, the control unit 12a returns to step S201. On the other hand, if the two devices can be combined (S207, Yes), the server 20 instructs each device about the link destination (S208). And the control part 12a changes the display of the display part 11 (S209), and complete | finishes a process.

  FIG. 10 is an explanatory diagram when the television 22 and the speaker 23 are linked. As illustrated in FIG. 10A, the icon 42 corresponding to the television 22 and the icon 43 corresponding to the speaker 23 are already displayed on the display device 10a. In this state, when the icon 43 is moved and overlapped with the icon 42, device information of the television 22 and the speaker 23 is sent to the server 20, as shown in FIG.

  As illustrated in FIG. 10C, the server 20 instructs the television 22 to use the speaker 23 as an output device, and instructs the speaker 23 to receive an input from the television 22. For this instruction, the output port address of the television 22 and the input port address of the speaker 23 are used. As a result, the television 22 uses the speaker 23 as an output device and outputs sound.

  In the case of ending the linkage of devices, the linkage end operation can be performed by separating the icons corresponding to the linked devices by performing an icon movement operation or the like.

  Further, as disclosed in FIG. 10-4, the corresponding device can be operated by performing an input on an individual icon. For example, when contact with the icon 43 is detected, the control unit 12 a displays an operation menu of a speaker that is a device corresponding to the icon 43. The operation menu of the speaker 23 includes volume and balance operations. When an operation input is performed according to the operation menu, the control unit 12a transmits the operation content to the server 20. The server 20 reflects the operation input performed on the display device 10a on the speaker 23 by transferring the received operation content to the speaker 23 which is a corresponding device.

  FIG. 11 is an explanatory diagram of the association between the mobile phone and the keyboard. When the mobile phone 24, the digital camera 21, and the keyboard 25 are placed on the display device 10a as shown in FIG. 11-1, the icon 44 of the mobile phone 24, the icon 41 of the digital camera 21, and the keyboard as shown in FIG. 25 icons 25 are displayed.

  The icon information is stored in the icon storage unit 15, and as shown in FIG. 11C, the icons 44, 41, and 45 continue to be displayed even after the mobile phone 24, the digital camera 21, and the keyboard 25 are removed.

  11-4, when the movement operation with respect to the icon 45 is received and the icon 45 overlaps the icon 44 as illustrated in FIG. 11-5, the control unit 12a displays the keyboard 45 and the icon corresponding to the icon 45. It is recognized as a linked finger operation of the mobile phone corresponding to No.44.

  The control unit 12a that has recognized the linkage operation notifies the server 20 that the linkage operation has been accepted by blinking the icon 44 as shown in FIG. 11-5, and the mobile phone 44 and the keyboard as shown in FIG. 11-6. 45 information is transmitted. If the linkage is possible, the control unit 12a notifies that the linkage has been performed, for example, by displaying a line connecting the icon 44 and the icon 45.

  When the keyboard 25 is input after establishing the linkage, the keyboard 25 sends the input content to the mobile phone 24 via the server 20. Therefore, the keyboard 25 can be used as an input device for the mobile phone 24.

  FIG. 12 is an explanatory diagram of the linkage between the display device and the digital camera. When the digital camera 21 is placed on the display device 10a as shown in FIG. 12-1, the icon 41 of the digital camera 21 is displayed on the display device 10a as shown in FIG. 12-2.

  The icon information is stored in the icon storage unit 15 and, as shown in FIG. 12-3, the display of the icon 41 continues even after the digital camera 21 is removed. When detecting the selection operation on the icon 41, the control unit 12a displays a list of devices that can output data of the digital camera 21 corresponding to the icon 41. In the example shown in FIG. 12-4, the digital camera 21 itself, the electronic paper showing the display unit 11 of the display device 10a, and the screen of the server 20 are presented as output destinations. Also, the example shown in FIG. 12-4 is a state in which electronic paper is selected from the presented output destinations.

  Upon receiving the selection of the output destination, the control unit 12a displays a menu for selecting where to save the stored data, as shown in FIG. 12-5. The example of FIG. 12-5 is data stored in the main body of the digital camera 21 and data held by the server 20, and data associated with the digital camera 21 is presented as candidates, and the data in the main body of the digital camera 21. Is selected.

  The display device 10a notifies the server 20 that the data in the main body of the digital camera 21 has been selected, and the server 20 acquires data from the digital camera 21 as shown in FIG. 12-6. Thereafter, as illustrated in FIG. 12-7, the server 20 transmits the data acquired from the digital camera 21 to the display device 10a. The display device 10a displays data F1 and F2 received from the server 20 on the display unit 11 as illustrated in FIG.

  In this way, the display device 10a functions as an interface for linkage of various devices, and the display device 10a itself can be linked with other devices. Further, the server 20 can link with other devices in addition to determining whether or not to link, controlling the link destination, and relaying the link.

  As described above, the device linkage system according to the second embodiment stores the acquired device information and controls the linkage based on the operation on the display device. Therefore, once the device information has been stored, it can be controlled without bringing the display device closer to the device.

  In addition, even for devices that are not turned on or that are out of communication range, prepare the connection by specifying the connection between devices by a virtual link operation on the display device.
