PROPOSAL OF USER INTERFACE DESIGN BASED ON MENTAL MODEL AND PROCEDURE OF HUMAN DESIGN TECHNOLOGY

Introduction: There is no the well-established methodology based on mental models. The systematized methodology of the user interface design based on the mental model is needed. Objective: In this paper, the logical methodology of the user interface design based on the mental model was systematized and proposed. In addition, we designed an operation screen of a car navigation system using the proposal methodology by way of example. Methods: The proposal methodology was utilized a procedure of Human Design Technology (HDT). HDT is the logical and systematized methodology of a product development. In this proposal methodology, the methods that the authors had proposed regarding mental models before now were used each of the steps of HDT in the screen design process. Results & Discussion: We designed a car navigation system using the proposal methodology. We believe that the proposal methodology is useful in the design of operation screens.
