总结在本文中，我们提出了一个交互式系统，控制压力，而用刀切纸。目的是提高初学剪纸艺术的新手的剪纸技巧。我们的系统通过实时测量和评估切割压力来支持新手的技能提高。在这项研究中，我们使用一个刀片连接到一个压力传感器，它可以测量压力，坐标和切割时间的笔刀。我们已经开发了一个类似的支持系统，使用手写笔和平板设备。该系统允许用户通过跟踪体验专家的压力。剪纸是用刀剪纸而成的。本文中的实践系统提供了一个更类似于剪纸生产的环境中的实践。在第一个实验中，我们通过比较新手和专家之间的切割压力来观察切割能力的差异。结果，我们证实，新手剪纸的压力比专家高。我们开发了一个练习系统，通过提供专家的切割压力值信息来指导新手控制压力。该系统使用颜色和声音的同步显示来显示新手和专家之间的压力差异。使用这些功能，新手可以学习根据专家的经验调整切割压力。确定正确的切割压力是剪纸艺术中的一项关键技能，我们的目标是通过我们的系统来改善这一点。在第二个实验中，我们在刀装置上测试了练习系统的效果。我们比较了使用和不使用我们的系统时切割压力的变化、车间中使用的练习方法以及先前开发的基于触针的支持系统。因此，我们确认，与其他练习方法相比，使用刀具装置练习对新手控制切割压力的技能有更好的效果。
SUMMARY In this paper, we propose an interactive system for con- trolling the pressure while cutting paper with a knife. The purpose is to improve the cutting skill of novices learning the art of paper-cutting. Our sys- tem 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 sensor, which can measure the pressure, coordinates, and cutting time. We have developed a similar support system using a stylus and a tablet device. This system allows the user to experience the pressure of experts through tracing. Paper-cutting is created by cutting paper with a knife. The practice system in this paper provides practice in an environment more akin to the production of paper cutting. In the first experiment, we observed di ff erences in cutting ability by comparing cutting pressures between novices and experts. As a result, we confirmed that novices cut paper at a higher pressure than experts. We 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 di ff erence 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. 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. In the second experiment, we tested the e ff ect of the practice system on the knife device. We compared the changes in cutting pressure with and without our system, the practice methods used in the workshop, and the previously developed stylus-based support system. As a result, we confirmed that practicing with the knife device had a better e ff ect on the novice’s skill in controlling cutting pressure than other practice methods.
