Abstract
This paper studies on operability evaluation for steering mechanism of pleasure boats. Although some evaluation methods has been already proposed by our group and can show the evaluation results on the effectivity and efficiency for a simulation task, it is hard to say that those methods give the intuitive understanding for the evaluation results. And the questionnaire results to investigate the subject satisfaction are not quantitatively included in the final operability evaluation. Therefore, this paper proposes an operability evaluation method to lead the total evaluation result, which is easy to understand intuitively. Also, the total evaluation result of the proposed evaluation method includes the user satisfaction quantitatively.
