Abstract: 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.
