Geszten, Dalma2017-08-082017-08-082017Nowadays most people work in teams and team members usually work together using collaborative technology, which creates a special problem when evaluating usability. I argue that the existing methods: group usability testing method (Chen et al., 2013), collaboration usability analysis method (Pinelle et al., 2003) and team usability testing method (Hackman & Biers, 1992) do not cover all aspects of team usability. The main contribution of my work is examining people who work together as a team, on the same task, with the same collaborative tool, using separate computers. I analyze problems that arise using communication analysis, behavior analysis (on-screen behavior), and post-experiment interviews. In my doctoral research I propose and test a new team usability testing method which helps to explore team level usability problems and translate these findings to improve user experience of collaborative tools.enText/Conference Paper10.18420/ecscw2017_dc32510-2591
