Affective evaluation for material perception of bead-coated resin surfaces using visual and tactile sensations: Preparation of adjective pairs to clarify the color effect

Kansei/affective values are attracting attention as a new evaluation axis of commercial value. We performed affective evaluation experiments on the tactile material perception of bead-coated resin surfaces and found that physical attributes change affective evaluations. Then, we planned to perform new affective evaluation experiment by adding hues, one of the three elements of color, as an important attribute of surfaces as the next step of our research. For the experiment, we performed two preliminary experiments: the experiment to select appropriate adjective pairs, and the experiment to select the hue candidates. This report describes the first preliminary experiment. We performed an experiment to reduce the number of adjective pairs for affective evaluations. The experimental results were analyzed by correlation analysis and hierarchical clustering analyses. From the results of those analyses, we selected 21 adjective pairs.
