Unformatted text preview: Territoriality in Collaborative Tabletop Workspaces Stacey D. Scott, M. Sheelagh T. Carpendale Department of Computer Science University of Calgary 2500 University Dr. NW Calgary, AB T2N 1N4, Canada {sdscott, sheelagh}@cpsc.ucalgary.ca Kori M. Inkpen Faculty of Computer Science Dalhousie University 6050 University Avenue Halifax, NS B3H 1W5, Canada inkpen@cs.dal.ca ABSTRACT Researchers seeking alternatives to traditional desktop computers have begun exploring the potential collaborative benefits of digital tabletop displays. However, there are still many open issues related to the design of collaborative tabletop interfaces, such as whether these systems should automatically orient workspace items or enforce ownership of workspace content. Understanding the natural interaction practices that people use during tabletop collaboration with traditional media (e.g., pen and paper) can help to address these issues. Interfaces that are modeled on these practices will have the additional advantage of supporting the interaction skills people have developed over years of collaborating at traditional tables. To gain a deeper understanding of these interaction practices we conducted two observational studies of traditional tabletop collaboration in both casual and formal settings. Our results reveal that collaborators use three types of tabletop territories to help coordinate their interactions within the shared tabletop workspace: personal , group , and storage territories. Findings from a spatial analysis of collaborators tabletop interactions reveal important properties of these tabletop territories. In order to provide a comprehensive picture of the role of tabletop territoriality in collaboration, we conclude with a synthesis of our findings and previous research findings and with several relevant design implications.

INTRODUCTION Traditional tabletop workspaces have long been considered ideal collaboration environments for small groups. Consequently, many distributed CSCW researchers have relied on them to inform the design of collaborative virtual workspaces (e.g., [3, 20]). Tabletop workspaces can provide a high degree of workspace awareness, through peripheral awareness of others and their actions in the workspace [20]. Furthermore, the ability to orient items in various ways on a table helps mediate group interactions by enabling collaborators to define distinct regions in the tabletop workspace [7, 20]....
