In design activity that requires sensibility (e.g. costume design), stakeholders have images of the product and refine them incommunication. In this paper, the image is called “Mental image”. While the design process, it is important for stakeholders
to share their mental images smoothly. However, mental images are complicated arrangement of vague sensibility
information so it causes difficulty of communication among stakeholders. The aim of this study is to build a support systemfor communication of mental images. This paper discusses a mental image model, which is basis of the system, through an
ontological engineering approach.
