Theory-based design for easily learned interfaces

摘要: Many important computer applications require that users be able to use them effectively with little or no formal training. Current examples include bank teller machines and airport information kiosks. Today successful systems of this kind can only developed by iteration using costly empirical testing. This article aims provide a theoretical foundation for the design such systems, model learning exploration called CE+. The theory incorporates assumptions from (a) GOMS cognitive complexity (CCT) on representation procedural knowledge as productions, (b) EXPL examples, (c) research problem-solving processes simple puzzlelike problems. Design guidelines learned exploration, "design guessing," are derived theory. These principles compared those Norman (1988).
