This paper proposes a method of selecting design strategies for user interfaces for various controllers based on an analytic hierarchy process. The goal of this model is to modify the graphical user interface of a remote controller to one that is the most suitable for each user. This paper proposes a new model with six evaluation criteria -Physiological, Knowledge, Psychology, Complicated System, Complicated Peripherals, and Habit. As alternatives, we decided our design strategy for the user interface -Vision assistance, Cognition assistance, Operation assistance, Memorizing. This proposed method was realized and evaluated by incorporating a processor assumed to be for AV remote controller use as practical applications. This paper verifies its effectiveness. Keywords -Analytic hierarchy process; design strategy; optimized user interfaceI.

In this paper, we propose a new model for the design method of graphical user interfaces for audio visual remote controllers based on analytic hierarchy processes. The goal of this model is to reduce human error in order to modify the graphical user interface of a wireless remote controller to obtain the most suitable interface for every user. The proposed method is evaluated by a prototype assuming a real-time OS on an embedded microprocessor. Furthermore, we confirmed this proposal as effective.
