Performs processing to dynamically generate and display content such as inset.

  Next, the operated device 40 issues a remote operation command wait request to the Web server 20 (step S72). Thereby, the Web server 20 stores a pair of the user ID of the connection information of the operated person and the thread ID for identifying the thread being executed corresponding to the operated person in the thread list 213 (step S92). The thread is temporarily stopped (step S93).

  Next, the controller device 30 reads a zoom-in operation instruction and a photo area instruction script from the Web server 20 as content information 220 for remote operation (step S82). Next, the controller device 30 encodes a zoom-in operation instruction and a remote operation command indicating an instruction of a photograph area to be zoomed up (step S83), and issues the encoded remote operation command to the Web server 20 (step S84). .

  When receiving the remote operation command from the operation device 30, the Web server 20 stores data necessary for executing the remote operation command in the data area 212 (step S95). Here, the data includes, for example, the URL of the Web server 20 that stores a zoom-up display page or the like.

  Further, the Web server 20 acquires a thread ID from the thread list 213 based on the user ID of the operated person included in the remote operation command (Step S96), and resumes the thread corresponding to the acquired thread ID (Step S97). ). Next, the Web server 20 reads data from the data area 212 (step S98), and transmits a remote operation command indicating a zoom-up operation instruction and a photo area instruction to be zoomed-up to the operated apparatus 40 (step S99).

  When receiving the remote operation command from the Web server 20, the operated device 40 decodes the remote operation command (step S74). Thereby, a remote operation command indicating a zoom-in operation instruction and an instruction of a photo area to be zoomed in is executed. In this case, the operating content control apparatus 410 dynamically generates content such as reading a zoom-up operation script and a zoom-up display page as content information 220 from the Web server 20 and zooming up the photo area of the Web browser 300. Process to display.

(10) Effects of this embodiment In the remote operation system according to this embodiment, each operation device 30 of the operator registered in the user management information of the operated person acquires the connection information of the operated person. The remote operation command for the operated device 40 can be issued to the Web server 20 based on the connection information. Further, when the operated device 40 issues a remote operation command wait request to the Web server 20, the remote operation command received from the operating device 30 by the Web server 20 can be transmitted to the operated device 40. As a result, the browser 400 of the operated device 40 can be remotely operated by the browser 300 of the operating device 30.

  In this case, the operated device 40 can be remotely operated from the operating device 30 with a simple operation of issuing a remote operation command wait request to the Web server 20. Therefore, it is not necessary to perform a complicated operation of the operated person.

  In addition, since the operation device 30 can remotely operate the operated device 40 by issuing a remote operation command to the Web server 20, it is not necessary to perform a special setting for exceeding the firewall of the operated device 40. .

  Furthermore, since the connection information of the operated device 40 is transmitted to the operating device 30 registered in the user management information of each operated device 40, the operated device 40 is operated by the operating device 30 of the operator who is not desired by the operated user. Remote operation is prevented.

  Further, when the Web server 20 receives a remote operation command wait request from any of the operated devices 40, the thread corresponding to the operated device 40 is temporarily stopped, and the Web server 20 receives the request from any of the operating devices 30. When a remote operation command for the operation device 40 is received, the thread corresponding to the operated device 40 is resumed.

  Thereby, the operated device 40 can issue a remote operation command wait request to the Web server 20 at an arbitrary timing, and the operating device 30 can issue a remote operation command to the Web server 20 at an arbitrary timing. Therefore, remote operation of the operated device 40 by the operating device 30 can be executed at a timing desired by both the operated device 40 and the operating device 30.

  Further, since each operation device 30 can issue a remote operation command to the Web server 20 using the content information read from the Web server 20, the burden on each operation device 30 is reduced. In addition, each operated device 40 can execute a remote operation command using the content information read from the Web server 20, thereby reducing the burden on each operated device 40. Furthermore, since the operation device 30 and the operated device 40 can share the content information stored in the Web server 20, the efficiency of the entire remote operation system is improved.

  Each operation device 30 can execute the script group read from the Web server 20 in the browser 300 and display the HTML group read from the Web server 20 on the browser 300. Each operated device 40 can execute the script group read from the Web server 20 in the browser 400 and display the HTML group read from the Web server 20 on the browser 400. Thereby, the display of the browser 400 of the operated device 40 can be easily remotely operated from the browser 300 of the operating device 30.

  Further, since the Web server 20 is used, no special program is required for the operation device 30 and the operated device 40. Therefore, the entire remote operation system can be configured at low cost.

  Further, since asynchronous communication is used for communication between the operation device 30 and the operated device 40, even when the operated device 40 is in a state of waiting for a remote operation command, the operated device can be operated by the user as needed. Can be operated.
