Analysis of Affective Evaluation for Material Perception of Resin Surfaces: Combined Effect of Tactile Sensation and Hue

Abstract

We previously performed affective evaluation experiments on tactile material perception of bead-coated resin surfaces with different surface textures generated by such various physical attributes as resin materials, bead diameters and bead densities. Our results clarified the affective relation between beads-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 affective evaluation of the effect of hues and to select the hue candidates. With 21 adjective pairs (ex. masculine-feminine and relaxed-anxious), and seven hues (ex. yellow-red and blue-purple), we clarified the combined effect of the tactile sensation and the hues on the affective evaluations using combinations of actual bead-coated resin and 3D models. Our analysis results suggest that hue, bead diameter, and gender are important for affective evaluation.
