For emerging group technologies that require evaluations on long-term use and social norms, assumptions, and implicit rules that develop around the technologies, standard usability testing may not be adequate. At the same time, field based research that allows for observing technology use over long-term is costly in terms of time. In this paper, we present a rapid method that we call progressive scenarios, which could help replicate the processes by which interpretations evolve over time in natural settings and how invisible assumptions and social norms dictate the technology use. Using a preliminary design concept of a publicly available ambient personal information and communication system, we demonstrate how the method helped to elicit design implications.
