Explorability: inferences at the interface

摘要

The problem of determining the appropriate action in using a new interface, or a new feature of a familiar interface, can be characterized as a form of problem-solving. Using distributed cognition as leverage to approach this problem, explorability is proposed as a framework within which to examine the inferences required to map the desired goal onto an appropriate action. Explorability is supported by consistency. affordances, and culture, each a constraint limiting the space of possible inferences. The three components are described, and the interaction of these three concepts is examined both as a problem and an opportunity for interface designers. The explorability framework is examined as an analytical tool to make explanations and predictions for interface designs.
