Role-Based Chatting

Role-based collaboration (RBC) is proposed to support improved human collaboration through more usable human-computer interfaces. To satisfy the objectives of RBC, new practical tools are required. Role-based chatting is a typical instance of role-based collaboration. To design a role-based chatting tool involves almost all the fundamental problems of RBC. This paper presents the design problems of role-based collaboration including model, engine and interface design, illustrates the scenario of role-based chatting, and describes the implementation of a role-based chatting tool including its architecture and components. The design of the chatting tool reflects all the principles outlined by role-based collaboration. This tool shows that role-based collaboration is practical and feasible. It also shows the possibility of building more complex role-based systems.
