Suitable graphical user interface selection based on human errors using analytic hierarchy process

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 the human error in order to modify the graphical user interface of a wireless remote controller to obtain the most suitable interface for every user. This paper proposes a new model with the seven evaluation criteria; inherent ability, lack of skill, lack of knowledge, slip, lapse, mistake and violation. As alternatives, we decided on four design strategies for the user interface; vision assistance, cognition assistance, operation assistance, and memorizing. The proposed method is evaluated by a prototype assuming a real-time OS on an embedded microprocessor. Furthermore, we confirmed this proposal as effective.
