半透明半明确协作框架下远程指针协同感知研究

远程指针协同感知是CSCW系统的关键技术之一，首先提出了半透明半明确协作框架下指针共享原理，包括鼠标移动消息事件的截取和鼠标消息事件和执行模式，然后提出了指针一致性维护和指针映射方法，给出了指针映射前、后处理算法和基本映射思路，最后研究了动态指针与语义重载的实现框架，构造了动态指针的模拟资源，设计了远程指针的感知域和重载语义，原型系统的实践表明这些技术方法是正确可行的，有利于增强协作者的群体意识，促进协同工作的进行。

TELEPOINTERS AND COOPERATIVE AWARENESS IN SEMI-TRANSPARENCY AND SEMI-AWARENESS CSCW SYSTEMS

Telepointer is one of the key issues in cooperative awareness. Conventional methods do not work in semi-transparency and semi-awareness CSCW systems. Firstly, a novel method of sharing telepointers is explored in semi-transparency and semi-awareness collaboration systems. Local interception and remote execution models of mouse events are described. Secondly, consistency maintenance of teleprinters for customary and tailored Windows interfaces are presented. The maintenance is based on telepointers mapping. Basic preprocess and postprocess algorithms of mapping ideas are provided. Finally, a framework of dynamic telepointers and semantics overloading is outlined. Two kinds of animating widgets for dynamic telepointers are constructed. Awareness fields and overloaded semantics of dynamic telepointers are designed. The proposed approaches have been implemented and tested in a prototypical CSCW toolkit, CoCADToolAgent, which is more flexible and of better collaboration performance than application sharing toolkit, such as Microsoft NetMeeting.
