Designing and evaluating the mobile experience through iterative field studies

This experience report describes using iterative field studies to design and evaluate the mobile experience of soundtransit.org. One study aimed to evaluate the design of paper prototypes early in the design process and another study was conducted to test the implementation of an interactive prototype. In this report, we share our experience to provide readers with lessons that can be applied to conducting their own mobile field studies. Finally, we describe some of the broader impacts that have resulted from this work.
