looking ahead – field trials in iterative and exploratory design of ubicomp systems
DESCRIPTION
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.TRANSCRIPT

MOTIVATION
› A major concern is to study how use practices and context of use emerge and develop over time when we introduce new technology.
Problem: › A mismatch between how field trials are understood and practiced, and
the very nature of ubicomp systems. › Use situations that are not well understood and in the making. › Field trials are frequently conducted in a ‘design then study’ mentality.
Thinking of field trials as a part of an iterative design process in order to look ahead rather than back.

OUR APPROACH: OPENLY INTERACTIVE
› We attract, rather than recruit, actual future users to an open system.
› We interact with (some of) them directly.
› We take their experiences of using the system as a springboard for in-depth explorations of their perspectives and insights about › the concrete system, › the broader concept, › and potentials and tensions for future approaches in general.

LOOKING AHEAD
› Studies based on trials that ‘leave use alone’ will always look back.
› We need ways of working with fully functional prototypes to look ahead towards use practices that are still in the making.
› Thinking of field trials as a part of an iterative design process in order to look ahead rather than back.
