Impact of practice effect on each difficulty of cutting skill

Abstract

In this paper, we aim to measure the cutting skill for creative paper cutting and increase practice effect. The practice effect changes according to the difficulty level of the cutting pattern and the skill level of the user. The cutting pattern of the picture consists of a straight line and a curved line, and we generalized the index of difficulty (ID) based on Steering law. One of cutting skills that shows the difference between novices and experts is time to cut. Besides, we developed a system consisting of a drawing display and a stylus with a knife to measured the cutting movement times (MT). The system measures MT according to the ID of the cutting pattern. We confirmed skill improvements by measuring changes in MT with various patterns. Additionally, we measured the reduction rate of MT to investigate the effectiveness of practice with various IDs. As a result, we confirmed the difference in practice efficacy according to each IDs.
