The Evaluation of GUI Design using Questionnaire and Multivariate Testing

To design a graphical user interface (GUI) in a computer system, the UI designer should understand all components of system, procedures, and user’s experience. Therefore, the UI designer must transform the user’s requirements into system story, procedures, and functions which will be fitted to the user’s needs. A good GUI design must be easy to see by the user e.g., “left-to-right” and “top-to-bottom” directions and the omitted usage of scroll bar for exploring the hiding part of a GUI. There are many tools used to collect the feedback and evaluate the best GUI design such as the questionnaire, the interview, the A/B testing, and the multivariate testing. In this paper, we propose the user testing method for the designing of Thai traditional weaving dashboard originated by the Royal Thai Silk Conservation Village Project, the Office of Sericulture Conservation and Standard Conformity Assessment, the Queen Sirikit Department of Sericulture, Ministry of Agriculture and Cooperatives. There are 5 variables used for the design evaluation: utility, functionality, ease of use, consistency, and satisfaction. The experimental results yield 3.927, 3.890, 4.027, 3.981, and 3.945, respectively.
