There is an increasing need to automate handwork by highly-skilled workers in industry. However, human’s motion contains time and spatial perturbations, and it makes the automation difficult. In author’s previous study⁽¹⁹⁾, the handwork was precisely expressed in dynamical system, and a mathematical model was established to analyze the time and spatial perturbation of an individual. In this report, the mathematical method is expanded by Lattice theory to deal with interpersonal spatial perturbation between individuals. The mathematical model is then applied to brush stroke motions of Japanese calligraphy to verify its effectiveness. As a result, a methodology is established to quantitatively evaluate proficiency levels of highly-skilled handwork based on intrapersonal and interpersonal spatial perturbation, and to provide guidelines for workers learning the handwork.
