Abstract
With the prosperous development of smartphone’s intelligent portable devices nowadays, there is also an increasing demand and growth of touch panel, which will bring a trend of extensive use of touch panel in the future. Therefore, by shortening the operational process to achieve better operation efficiency, this approach aims at creating a best of the key configuration. Besides providing the users with a convenient and comfortable operation environment, this approach will establish a systematic optimization configuration of interface for the future designers to use easily. This approach chooses intelligent portable devices’ audio-visual software human-machine interface as its research target. The questionnaires will be applied to obtain the user's mental models, from which the survey results and statistic can classify the general user’s habits and preferences. Furthermore, the key configuration can be set based on the questionnaire analysis, and the genetic algorithm can be executed to design an interface configuration which matches between the users’ mental models and the concept of software interface. Through the operation of genetic algorithms, this approach proposes an optimization configuration of audio-visual software human-machine interface. This design make it is easier to operate for the users with higher efficiency, and the same concept can also be applied to other related devices structurally operated by buttons, for which we expect a more humane and more efficient interface design to achieve a better operation effect in the future.
