Understanding how users recognize an icon is as complex as understanding visual perception itself. Because the cognitive factors that affect the evaluation of icons have not been properly analyzed, the comprehension of pictorial symbols is typically ill-defined. The fuzzy approach seems to be a better way to provide a possible solution to this methodological problem. To remedy the disadvantage of the conventional approach, and to use the full potential of the computer as an aid to icon design, the purpose of this study is to propose a fuzzy graphic rating as a technique for evaluating the icon design. Although a fuzzy rating can be conducted using a pencil and paper technique, analysis is a difficult part through obtaining the rating in a pencil and paper method. In addition, iconic interface design is a highly graphic-oriented, so the graphic is playing an important role in design process. Therefore, based on the CAD technology and the fuzzy graphic rating as an approach to iconic interface design, this paper is intended to propose a more systematic treatment of iconic interface design than has hitherto been made. In this paper, a FUZWD (FUZzy Reasoning in Icon Design) system was implemented to provide designers with the predictive information using the fuzzy reasoning approach.
