Bezerianos, Anastasia and McEwan, Gregor (2008): Presence disparity in mixed presence collaboration. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3285-3290. Available online

“We present the design of an experiment investigating presence disparity in mixed presence collaboration using digital tabletops. In an attempt to verify previous work and relate their results, we examined different presence representations of remote collaborators: audio, video, telepointers and video arms. Our early results show some interesting trends that we are currently investigating in more detail through further analysis of our data.”

Romero, Natalia, McEwan, Gregor and Greenberg, Saul (2007): A field study of community bar: (mis)-matches between theory and practice. In: GROUP07: International Conference on Supporting Group Work 2007. pp. 89-98. Available online

“Community Bar (CB) is groupware supporting informal awareness and casual interaction. CB's design was derived from three sources: prior empirical research findings concerning informal awareness and casual interaction, a comprehensive sociological theory called the Locales Framework, and the Focus/Nimbus model of awareness. We conducted a field study of a group's on-going CB use. We use its results to reflect upon the matches and mis-matches that occurred between the theoretical and actual usage behaviors anticipated by our design principles vs. those observed in our deployment. As a critique, this reflection is an important iterative step in recognizing flaws not just as usability problems, but as an incorrect translation of theory into design that can be re-analyzed from a theoretical perspective.”

“Mixed presence collaboration combines distributed and collocated collaboration -- there are multiple distributed sites, each with a collocated group. While collocated collaboration and purely distributed collaboration are each the subject of rich bodies of research, the combination is less well explored. In this paper we present our initial concepts of awareness support in mixed presence collaboration. We present this as a first version model of awareness. The selected literature we have used to inform the model is drawn from collocated research and distributed research as well as the small body of work addressing mixed presence collaboration directly. In this paper we present a discussion of this relevant literature and use it to explain our model. We also offer a sample of applying the model through the use of a scenario.”

McEwan, Gregor and Greenberg, Saul (2005): Supporting social worlds with the community bar. In: GROUP05: International Conference on Supporting Group Work November 6-9, 2005, Sanibel Island, Florida, USA. pp. 21-30. Available online

“The Community Bar is groupware supporting informal awareness and casual interaction for small social worlds: a group of people with a common purpose. Its conceptual design is primarily based on a comprehensive sociological theory called the Locales Framework, with extra details supplied by the Focus/Nimbus model of awareness. Design nuances are strongly influenced by observations and feedback supplied by a community who had been using both the Community Bar and its Notification Collage predecessor for a total of five years. As a consequence, Community Bar\'s design supports how communities of ad-hoc and long-standing groups are built and sustained within multiple locales: places that offer a group the site and means for maintaining awareness of one another and for rapidly moving into interaction. This includes a person\'s lightweight management of his or her membership in multiple locales, as well as ones varying engagement with the people and artefacts within them.”
