Prototypes in the wild: Lessons from three ubicomp systems

Evaluations of three ubicomp systems at multiple design stages provide a better understanding of evolution process of the ubicomp evolution techniques. The degree to which a ubicomp application is pleasing and useful depends on the designer's ability to understand and meet user needs. It was determined that paper prototyping is useful for rapid iteration of graphic designs in lab settings and for getting early feedback on an application's situated use. The field-based interactive prototypes provide invaluable feedback on a system's use and co-evolution.
