Unformatted text preview: Collaborating around large interactive displays: which way is best to meet? Yvonne Rogers and Siân Lindley Interact Lab, School of Cognitive and Computing Sciences, University of Sussex, Brighton, BN1 9QH, UK Abstract. Large interactive displays are increasingly being situated in a variety of work and public places. An assumed benefit is that the technology provides a large interactional space that makes it simpler to support collaborative work. A study was carried out investigating how the physical orientation of a shared display affects group collaboration. Stark differences were found between the way groups coordinate their work and collaborate when using an interactive table-based display versus a wall-based display. The physical affordances of the displays engender different social affordances: the table display encouraged group members to switch more roles, explore more ideas and follow more closely what each other was doing. In contrast, groups found it socially awkward to collaborate around the wall display. In a follow-up study, where both displays were made available, groups adopted a greater division of labour and more rigid roles, resulting in more efficient working but less equity of idea generation. We discuss why this is so in terms of the interactional resources that come into play, and suggest that the threshold for what is considered acceptable social behaviour depends on the physical arrangement of technology. Introduction Recently, there has been a growing interest in situating large interactive displays in a variety of work and public places to facilitate collaboration. Motivations include instilling a sense of community (Churchill et al, 2002), providing enhanced up-to date information about a work practice (Greenberg and Rounding, 2001) and initiating informal communication among strangers (Rogers and Brignull 2002; McCarthy, 2002). Many kinds of displays are now available that can be used to view and/or interact with information, including front and back projected wall displays, large flat PC-based screens, plasma displays, Mimio and SmartBoards. A key issue is how to design the displays so that they invite interaction (Agamanolis, 2002) and collaboration (Russell and Gossweiler, 2001). An assumed benefit of situating large displays in these kinds of social settings is that they provide a large interactional space, that should make it simpler to support collaborative work (Russell, 2002) that is more fluent (Johnason et al, 2002). Compared with a co-located group trying to work around a single user PC, large displays lend themselves to being interacted with more directly by multiple users; who can point to and touch information being displayed, while simultaneously viewing the interactions and having a shared point of reference. The physical affordances are quite different, resulting in the setting up of different social affordances . By this, we mean how certain social behaviours are encouraged and seen as acceptable by way of the physical properties of the interactional space (cf.seen as acceptable by way of the physical properties of the interactional space (cf....
