Method for transmitting user operation case

Abstract

The present invention discloses a method used for transmitting user operation events. A system for realizing the method comprises at least two terminal facilities and a middle server, wherein the terminal facilities are separately connected with a middle server network; each terminal is composed of a user interface module, a collection upgrade processing module, a logic conversion module, a buffer module and a sending and receiving module which are connected in sequence. The present invention has the advantages that a layered software architecture improves extensibility of the system, and modifies just a certain layer of the system and has less influence on the other layers; a data presentation module based on overall situation identification avoids the naming conflict; a transferring strategy based on a mixed mode lowers the server loading and reduces the network conflict; a receiving and sending device based on a multi-threading concurrence mechanism improves processing and transferring performance of whiteboard events; a concentrated control method solves concurrence control problems and can effectively ensure the timeliness and the consistency of the data, thereby improving the working efficiency. The method used for transmitting user operation events provided by the present invention can be widely applied in various CSCW systems and has high utility value.

Description

technical field [0001] The invention relates to the field of communication and computer network, in particular to a method for transmitting user operation events. Background technique [0002] With the rapid development of computer science and technology, especially communication technology and computer network technology, a new research field - Computer Supported Cooperative Work (CSCW) has emerged. The shared electronic whiteboard is a typical CSCW application. By using hardware I / O devices such as mouse, keyboard, stylus, and touch screen, each collaborative user can draw graphics, type text, annotate, cut, and copy pictures on the electronic whiteboard, and simultaneously display them on the whiteboard interface of other users. In order to achieve the purpose of resource sharing and real-time communication. How to effectively capture, organize and package electronic whiteboard events is an important factor to promote people's work interaction and collaboration. [000...

AI Technical Summary

Problems solved by technology

The disadvantage of this transmission method is: when multiple users operate the electronic whiteboard in cooperation, other terminals can only see the operation results of the operation terminal after the operation terminal completes a complete operation entity, and they cannot understand the actual operation process of the operation terminal

This cannot meet the requirements of the whiteboard system to ensure the real-time and consistency of data, let alone improve the work efficiency of each end user
