Abstract

A terminal to be remote controlled via a communication network is provided with a communication controller 26A for receiving a remote operation message from a control terminal, a remote operation basic controller 20A for delivering remote operation input data extracted from the received message to an operating system, and an operation recording and playing controller 25A for recording and playing the remote operation input data and specific terminal operation data as remote operation history data.

Claims

1. A terminal for a computer network, comprising:

means for receiving a remote operation message from a distant terminal through a communication network;

means for entering remote operation input information extracted from the received remote operation message into an operating system; and

history recording means for recording the remote operation input information and transition of display on a terminal display screen in response to the remote operation input information as remote control history data.

6. A terminal for a computer network according to claim 1 , wherein the history recording means includes means for automatically starts remote operation history recording when it is judged that remote operation input information from the distant terminal or a terminal operation in response to the remote operation input information satisfies a predetermined start condition.

9. A terminal for a computer network according to claim 1, wherein the history recording means includes means for automatically stops remote operation history recording when it is judged that remote operation input information from the distant terminal or a terminal operation in response to the remote operation input information satisfies a predetermined stop condition.

12. A terminal for a computer network according to claim 1, wherein remote operation history recording is stopped after a lapse of a predetermined time period from the start of remote operation history recording.

2. A terminal for a computer network, comprising:

communication control means for receiving remote operation input information from a distant terminal through a communication network;

remote operation basic control means for entering the received remote operation input information into an operating system; and

history recording means for creating a remote control history file according to the remote operation input information and information supplied from the operating system to an application program and a display controller.

4. A terminal for a computer network according to claim 2, wherein said remote operation basic control means generates a message for reflecting the change in a terminal screen in response to the remote operation input information to said distant terminal, and sends the generated message to the network via said communication control means.

7. A terminal for a computer network according to claim 2, wherein the history recording means includes means for automatically starts remote operation history recording when it is judged that remote operation input information from the distant terminal or a terminal operation in response to the remote operation input information satisfies a predetermined start condition.

10. A terminal for a computer network according to claim 2, wherein the history recording means includes means for automatically stops remote operation history recording when it is judged that remote operation input information from the distant terminal or a terminal operation in response to the remote operation input information satisfies a predetermined stop condition.

3. A terminal for a computer network, comprising:

communication control means for receiving a remote operation message from a distant terminal through a communication network;

remote operation basic control means for entering remote operation input information extracted from the received remote operation message into an operating system;

hooking means for capturing information supplied from the operating system to an application program and a display controller; and

history recording means for creating event data according to the remote operation input information and the information captured by the hooking means and for recording the created event data in a remote control history file.

5. A terminal for a computer network according to claim 3, wherein said remote operation basic control means generates a message for reflecting the change in a terminal screen in response to the remote operation input information to said distant terminal, and sends the generated message to the network via said communication control means.

8. A terminal for a computer network according to claim 3, wherein the history recording means includes means for automatically starts remote operation history recording when it is judged that remote operation input information from the distant terminal or a terminal operation in response to the remote operation input information satisfies a predetermined start condition.

11. A terminal for a computer network according to claim 3, wherein the history recording means includes means for automatically stops remote operation history recording when it is judged that remote operation input information from the distant terminal or a terminal operation in response to the remote operation input information satisfies a predetermined stop condition.

14. A remote operation history recording method according to claim 13, wherein the remote controlled terminal judges whether or not the remote operation input information extracted from the remote operation message received from the control terminal or a program operation executed in response to the remote operation input information satisfies a predetermined start condition, and if the predetermined start condition is satisfied, remote operation history recording is started at the remote controlled terminal to store event information based on the remote operation input information and event information indicating the results of execution of the program operation.

13. A remote operation history recording method for use in a computer network system in which one of a plurality of terminals is used as a control terminal for conducting remote operation of another terminal to be a remote controlled terminal, the method comprising the steps of:

sending a remote operation message from said control terminal to said remote controlled terminal;

extracting remote operation input information from the remote operation message received by the remote controlled terminal, and executing a program operation at the remote controlled terminal according to the extracted remote operation input information;

storing, as operation history data, event information generated at the remote controlled terminal according to the remote operation input information;

sending a message indicating the results of execution of the program operation from the remote controlled terminal to the control terminal; and

storing, as operation history data, event information indicating the results of the program operation at the remote controlled terminal.
