We investigate in which forms field trials are a workable model as part of an exploratory design process for sporadic, mobile, non-work settings. A major concern of evaluating ubicomp systems is to study how practices and context of use emerge and develop over time when new technology is introduced. To introduce a sophisticated version of our own prototype in the course of an iterative design process, we conducted a public field trial of the system---a new platform for mobile democratic discussions in municipal planning---that we distributed via the Android Market. However, it turned out to be surprisingly difficult to evaluate our design in a setting that stretches over time, place, and without a preselected set of users. Analyzing our difficulties, we develop a general model for methods studying ubicomp systems. On the basis of this model, we characterize an openly interactive approach to field trials in order to look ahead rather than back.
