Abstract

We build on our prior work with computer-supported teams performing a complex decision-making task on maps, where the distinction between content and process common ground is proposed. In this paper we describe a distributed geo-collaboration software prototype. The system design rationale was gleaned from fieldwork, literature on team cognition, and an earlier lab study introducing a reference task with face-to-face teams. We report on a controlled experiment that evaluates this design rationale. Distinct sets of measures show that that the prototype supported both content and process common ground, offsetting the costs imposed by the distributed setting. We interpret the results in relation to prior work on common ground and draw implications for moving beyond current models of sharing and coordination.
