Two Cases for Traces

In this paper we activate theoretical principles for HCI and CSCW in analysis design of collaborative technologies. We critically evaluate about how technologies mediate activities through two empirical cases regarding smart speakers writing, respectively. Common to them is that both common objects mediating artifacts are set a mixed virtual physical setting. Principles from activity theory examined, specifically with focus on people use as mediators collaborate joint activity. As part questioning the cases, also position affordances relation principles. engage by using analytically constructively. Our targets traces possible construct has potential constructively aid collaboration across cases. explore what seems be lack support, particular framing, past activities, connected objects, other users, etc. With an initial hypothesis could mechanism would support these kinds better future redesign, out further their possibilities, they conceptually grounded supported. present oriented questions help researchers designers identify instances collaboration.
