Affective evaluation for material perception of bead-coated resin surfaces using visual and tactile sensations under virtual and real environments

Affective values continue to attract attention as a new evaluation axis of commercial value. Our research emphasizes the affective value of contents based on the physical attributes of containers/packages. We previously performed affective evaluation experiments on the tactile material perception of bead-coated resin surfaces with different surface textures generated by such physical attributes as resin materials, bead diameters, and bead densities. Our results clarified the affective relationship between bead-coated resin surfaces and related adjectives. In our new affective evaluation experiment, we added hues, which is one of the three elements of color, and performed two preliminary experiments to select appropriate adjective pairs for the affective evaluation of the effect of hues and to select hue candidates. With 21 adjective pairs and seven hues, we experimentally clarified the combined effect of tactile sensations and hues on affective evaluations using combinations of actual bead-coated resin and 3D models with both male and female participants in their 20's or 40's/50's. Our analysis results suggest that hue and bead diameter have stronger effects than gender and age-generation, suggesting that the influences of physical attributes are stronger than customer gender and age, which is useful from the viewpoint of container/package manufacturing and can be applied to web services with visual and tactile information.
