Visual Evaluation Factors of Interior Material Textures and Physical Properties Related to Those Factors

Abstract

In this study, a sensory evaluation experiment of automotive interior material textures was conducted, and factor analysis and multiple regression analysis were performed to elucidate the visual evaluation factors. As a result, 7 evaluation factors were extracted. In those evaluations, "authentic", "deep", and "unique" are three effective main factors affecting on the overall evaluations of “high-grade” and “preferable”. Furthermore, highlights and shades of brightness and so on were extracted as candidates of physical properties affecting “deep” as the main factors.
