Abstract

In this paper we investigate strategies to support knowledgesharing in distributed, synchronous collaboration. Our goalis to propose, justify, and assess a multiple view approachto support common ground in geo-collaboration within multi-roleteams. We argue that a collaborative workspace, which includesmultiple role-specific views coordinated with a team view, affords a clear separation between role-specific and shared data, enablesthe team to filter out role-specific details and share strategicknowledge, and allows serendipitous learning about knowledgeand expertise within the team. We discuss some key issuesthat need to be addressed when designing multiple views asa collaborative visualization. We illustrate the design featuresof a geo-collaborative prototype that address these issues in the context of two collaborative scenarios. We finally describe alaboratory method for investigating how multi-role teams establishcommon ground while the amount of prior shared knowledgeand the type of visualization are experimentally manipulated.
