Outline of Final Research Achievements |
The purpose of this research is to construct a Shitsukan quantification prototype system that estimates the visually perceived Shitsukan from an actual object with regard to perceptual gloss, transparency, and roughness. Both perceptual information processing analysis based on psychophysical evaluation using diffuse and directional illuminations and physical information analysis based on optical measurements were conducted on real objects with various materials, colors, and surface unevenness. The results showed that a model could be constructed to estimate the perceptual quantity of each Shitsukan from the physical features acquired by optical measurement. Specifically, for perceptual gloss, the results suggest the possibility of constructing a universal quantification system that is not limited to the materials that have been treated in existing research but can be applied to as many as 10 types of real materials, such as stone, leather, and resin.

Academic Significance and Societal Importance of the Research Achievements |
本研究により構築した質感定量化プロトタイプシステムは、心理物理評価に基づく知覚情報解析と物理情報解析の双方からのアプローチによって、人間がどのような物理情報を用いて質感を知覚しているのかという質感知覚メカニズムの解明へとつながる学術的意義がある。更に、複数の材質に適用可能な汎用的なシステムの構築は、様々な産業分野の共通指標として活用される可能性を有することから、社会的意義も併せ持つ。プロトタイプシステムを更に発展させて対象物体を拡張できれば、様々な質感を対象とした定量化システムは、求める質感からものづくりに挑む要素技術としての活用も見込まれる。
