Abstract

We investigated the effect on synchronous communication of adding a Shared Workspace to audio, for three tasks possessing key representative features of workplace activity. We examined the content and effectiveness of remote audio communication between pairs of participants, who worked with and without the addition of the Workspace. For an undemanding task requiring the joint production of brief textual summaries, we found no benefits associated with adding the Workspace. For a more demanding text editing task, the Workspace initially hampered performance but, with task practice, participants performed more efficiently than with audio alone. When the task was graphical design, the Workspace was associated with greater communication efficiency and also changed the nature of communication. The Workspace permits the straightforward expression of spatial relations and locations, gesturing, and the monitoring and coordination of activity by direct visual inspection. The results suggest that, for demanding text-based tasks, or for complex graphical tasks, there are overall benefits in adding a visual channel in the form of a Workspace. These benefits occur despite the costs involved in attempting to coordinate activity with this unfamiliar form of communication. Our findings provide evidence for early claims about putative Workspace benefits. We also interpret these results in the context of a theory of mediated communication.
