“…Workplace interaction is a phenomenon that has been a focal object of study within the areas of HCI (human-computer interaction) and CSCW (computer-supported cooperative work) for around 20 years now. During this time, the character of workplace interaction has been explored from a wide range of perspectives ranging from empirical studies of one-shot interaction (Aaronson & Carroll, 1987), serendipitous interaction (Landgren & Nuldén, 2007), casual interaction (Borning & Travers, 1991;Whittaker, Frohlich, & Daly-Jones, 1994;Whittaker, Swanson, Kucan, & Sidner, 1997), long-term social interaction (Whittaker, Jones, & Terveen, 2002), and spontaneous interaction (Lim, Zhang, Zhu, & Zheng, 2007), to studies of formal interaction (Oehlmann, Thoben, & Weber, 1997), planned interaction (Isaacs, Tang, & Morris, 1996), and structured interaction (Rogers, 1995). While this body of research has mainly focused upon the formal and informal aspects of workplace interaction, we have so far seen few studies with an explicit focus on how individuals active in these social work arrangements go about searching for each other to establish interaction, and how social factors govern this behavior.…”
