In this paper, we propose an interactive system for controlling the pressure while cutting paper with a knife. Our system supports skill improvement for novices by measuring and evaluating their cutting pressure in real time. In this study, we use a knife with a blade attached to a stylus with a pressure sensitive sensor, which can measure the pressure, coordinates, and cutting time. We compare the cutting pressure values of novices with those of artists and thereby observe the difference in their cutting skills. We have also developed a practice system that guides the novices on controlling the pressure by providing information on the cutting pressure values of experts. This system shows the difference in pressure between novices and experts using a synchronous display of color and sound. Using these functions, novices learn to adjust their cutting pressure according to that of experts. The purpose of this research is to improve the cutting skill of novices learning the art of paper-cutting. Instructors typically teach the novices how to control the cutting pressure during paper-cutting workshops, as novices tend to cut paper with an unstable and higher pressure than necessary. Determining the right cutting pressure is a critical skill in the art of paper-cutting, and we aim to improve the same with our system. We verify the effect of our system by practicing paper-cutting in various methods and comparing the cutting pressure values obtained. It is evident from the results that novices who practice with our system show progress on the average and variance of cutting pressures.
