Abstract

We studied the process of sharing and managing knowledge (common ground process) in three-member teams performing emergency management planning tasks on shared maps. We built a reference task and a role-based multi-view prototype for studying this process. In this paper we empirically test the claim that common ground increases through joint experience on a task over time. We model the common ground process using a realistic task, a controlled setting, and multiple measures. We present findings from the analysis of questionnaires, communication transcripts, videos, and artifacts.
