ABSTRACT This paper introduces a model and related tool to evaluate GUI design interactively using Web. We propose a Web-based tool to evaluate GUI design for both designers and users. We have designed and pilot tested an interactive Web instrument to obtain users’ and designers’ opinions, suggestions, and reactions about GUI design both locally and distributively. We have implemented a questionnaire in a Web environment as a tool that can be administered and accessed distributively, anytime, anywhere, from a Web page. The tool has been applied to evaluate Web browsers and educational software. The scope and uses of this tool is discussed as well as further developments and applications. Finally, the incorporation of Java applets to this development in order to add more interaction to GUI evaluation is analyzed and discussed.
