Improve User Experience by Adjusting Draft Design through Retouching System for Paper-cutting Production

This study proposed a system for quantifying artistic production difficulty and adjusting difficulty via retouching, with an aim to improve production. A paper-cutting artwork was created controlling a knife to cut the designed paper. Paper-cutting draft designs have two parts: a white and black areas for cutting-out and painting, respectively. The difficulty level of the picture was measured based on the thickness of the cutting borderlines. Thus, in this study, a retouching system that reduces the difficulty of draft design by adjusting the line thickness was developed. Further, the effects of this system on a novice production was experimentally investigated. Consequently, the system was confirmed to improve accuracy and psychological state (flow state) via retouching the draft design.
