Using mobile media, museums may transcend institutional settings to highlight the significance and meanings of cultural heritage: framing art and design in the urban sphere, shedding light on nature in the wild, or bringing historic sites to life. The possibilities are manifold, but not straightforward, as augmenting the everyday without the help of a museum context can be tricky, and may upset traditional understandings of the curatorial. This is, however, not simply a problem in need of a solution but also a challenge that may inspire constructive reflection and innovation in the museum community. The PhD research project “Mobile Mediation of Fashion by Museums” explores how aesthetic and ethnographic design methods can be used to develop mobile experiences and articulate museological matters of concern. Building on user perspectives, expressed in response to cultural probes, the project has generated a design game to support projection and discussion of possible concept scenarios and their implications. The game format was used in a series of workshops with Designmuseum Danmark, to ideate and consider new ways to appreciate Copenhagen fashion culture via mobile media. This paper describes the project’s problem field, research methodology and process, in order to suggest how this approach could be used by museums confronting similar challenges.
