Current practice in automation includes a trend whereby control systems in industrial plants are increasingly being distributed, especially in process plants where geographically distributed processes require controllers to be placed close to the process being controlled. At the same time, however, it is also becoming increasingly evident that the use of DCCS (Distributed Computer Control Schemes) techniques alone will not be as effective as the technology could be. This is largely due to the lack of emphasis on the human role during the design of DCCS, and the consequent lack of appropriate support for operators. The design of operator support systems calls for the use of the techniques to facilitate both human-computer interaction (HCI) and human-human (HHI) interaction. The reason is that operators in process plants work in teams or groups: operators must not only work closely together (with common data and applications), but must also be able to see other team members' decisions and actions, as reflected in changes to shared data. In such situations, a concentration on HCI design is not enough; HHI must be considered so as to increase the effectiveness of cooperative work. This has led to the emergence of a special class of systems - computer-supported cooperative work (CSCW) - which support groups working together on a common application, in a way that makes any one user's action visible to all the others. Multimedia technology can improve the efficiency and effectiveness of such CSCW systems if it is used appropriately. To design such a CSCW system, a key is the development of an appropriate architecture upon which to base the system. In this thesis, a distributed whiteboard architecture, a network of sharable common workspace (whiteboard), is suggested.
