Tangible possibilities - envisioning interactions in public space

This article explores approaches to envisionment in the field of interaction design. Design fictions are introduced as a method to articulate future possibilities. Three case studies are described which explore interaction in public space. The fictions create imaginative projections with the intention of generating reaction and responses in the public that will lead to a greater understanding of the physical and conceptual design space. The first case study explored how citizens could anonymously comment on their relationship with a city. The second study encouraged participants to reflect on their habits and rituals and to view these through fresh eyes. The final case study sought to surprise and engage gallery visitors through an interactive piece that raised issues concerning the surreptitious capture of data. The paper concludes by reflecting on the utility of design fictions and the role they can play in concept envisionment.
