From Abstraction to Realization: Canonical Abstract Prototypes for User Interface Design REVISED

Canonical abstract prototypes are an innovative means for specifying and exploring visual and interaction design ideas. Intermediate between abstract task models and realistic or representational prototypes, canonical abstract prototypes provide designers with a standardized vocabulary for expre ssing visual and interaction designs independent of details of appearance and behavior. This common abstract design vocabulary facilitates comparison of designs as well as recognition and description of common design patterns. This paper introduces the basic concepts of abstract prototypes and covers recent refinements in the modeling notation and the set of canonical abstract components.
