The Research & Design Of The Cooperative Tools System

Along with global competition becoming acute and the computer network developing dramatically, Computer Supported Cooperative Work has been put importance on, because it can satisfy the individuation and diversification of customers' demands and the rapid changes on the market, by means of realizing quickly assembling and exploiting of geographically distributed design resource and shaping a team-based collaborative design mode inside and between the enterprises base on the networkMuch research work have been done on CSCW since it was put forward in 1980' s, some research results have been taken into use in some fields. But, as a necessary department of CSCW, cooperative tools have not absorbed enough attention. Cooperative tools system can supply a cooperative environment, in which cooperating participants can discuss with each other real-timely or unreal-timely by means of text, graph, video, voice, via computer network.The background of this thesis is a project of CSCW system for a design institute. The thesis focuses on two aspects: How to realize the reformation on technology, how to take full advantage of the new technology to adapt to developing requirements; How to make balance between generality and particularity, how to conclude an informational simulation of the real cooperative authoring task, and how to pay enough attention to the psychology of all the cooperating participants.Firstly, this thesis analyzes the cooperative tools' main function which CSCW system needs, based on the research for the CSCW system and requirement of the task, and then puts forward a mode of cooperative tools. In the model, B/S is the main body, C/S is the assistant. With this understanding, the thesis confirms the main frame of cooperative tools. Secondly, it introduces the key technologies, establishes configuration of B/S, and designs the video colloquy' s module for which COM and NetMeeting COM API are used. A prototype is implemented on the base of these researches. At last, the system is tested and some conclusions and...
