This paper reports on the evaluation of a digitallyaugmented exhibition on the history of modern media. We discuss visitors’ interaction with installations and corresponding interaction design issues, drawing on results from analysis of logfiles, interviews, and observation in the museum. We see this as an exploration into interaction design of interactive installations for public settings, using the evaluation as a case study on what makes an installation engaging and how it can provide an engaging experience for groups.
