Retouching System to Ease Difficulty of Craft Design for Paper-Cutting

We present our system for quantifying artistic production difficulty and adjusting retouching difficulty to improve production. A paper-cutting artwork is created by controlling a knife and cutting designed paper. Paper-cutting craft designs have two parts: a white area for cutting out and a black area for painting. We have measured the difficulty of the picture based on the thickness of the cutting borderlines. In this paper, we have developed the retouching system that eases the difficulty of craft design by adjusting the line thickness. We have experimented with the effect of this system on the novice's production. As a result, we found that the system improved the accuracy and psychological state (flow state) by retouching craft design.
