Abstract
With the extensive application of human machine interaction, user-interface design is currently a significant issue in intelligent portable devices. This paper focuses on the user-interface design and proposes an efficient procedure for the key configuration in the user-interface of intelligent portable devices. In this paper, we assume a possible operational user-interface scenario and adopt revised genetic algorithms to generate an adequate key configuration and friendly user-interface in audio-visual software. The proposed methodology may accelerate the procedure of user-interface design, and easier to obtain user-interface patterns. The entire protocol has the potential to be applied to other related intelligent devices, and offer an alternative user-interface design in intelligent portable devices. © 2013 Springer-Verlag Berlin Heidelberg.
