The use of graphical media in synchronous communication has received relatively little attention. This paper reports the results of an experimental study of graphical communication that systematically compares interaction in a task-oriented dialogue with and without a shared virtual whiteboard. Observations of the interaction show that a wide variety of communicative functions can potentially be served by graphical interaction. Analyses of both overall performance and communicative process demonstrate that graphical communication can provide a clear transactional advantage in communication. The results also show that participants develop their use of graphics, producing progressively more abstract graphical representations as their experience increases.
