Supporting multiple conference spaces in Group Teleworking System

The paper describes the user interface design of the Group Teleworking System (GTWS), which is designed to support multiple conference spaces. GTWS is developed as a real time collaboration system, often called a desktop conference system. Combining virtual meeting room representation and conference switching mechanism, GTWS provide an environment in which users can, through their own workstations, participate in more than one conference at the same time. GTWS is a prototype system including multipoint audio video unit with CODEC facility in it. Some of the experimental results observed in use in our laboratory and public exhibitions are also presented.
