Point contact and relative motion of drawing can identify individual traits

The action of drawing is one way people have of creating representations of arts. Usual approaches to study drawing action in human machine interaction has mostly focused on obtaining images produced by machines or robots. In this study, the creation process is treated not as image processing of output work by using a high-fidelity photographic image but as a relative function of medium during creation process. During the creation process, drawing materials, paints, papers and canvas themselves play roles of resistance against agents´ intents and actions. To put it extremely, they seem like other agents with different intentions from those of the drawing agent. Based on this design concept, a `relatively-moving drawing robot´ was constructed and utilized to implement experiments on human perception. We will discuss the emergence mechanism of human subjectivity by using the robotic system, and the results showed that point contact and relative motion during drawing can identify individual traits.
