An Application of the Semantic Differential to Icon Design

Previous studies have indicated that the semantic differential was effective in evaluating comprehension of icons. However, the capability of semantic differential ratings depends on whether the underlying rating factors have been chosen properly. It is necessary to find out what cognitive factors affect the evaluation of an icon. Then, these factors can be used as the basis for semantic differential ratings on the proposed icons during the design stage. Most of the studies are focused on the evaluation after the design is completed. Very few have ever mentioned the approaches of icon evaluation at the design stage to ensure the design quality. Therefore, the purpose of this study is intended to derive and validate the cognitive factors that affect icon designs, and to provide designers with a tool having predictive information for evaluating and modifying the proposed icons at an early design stage.
