This study aims to explore the influence of different light color temperatures and lighting illuminances on two kinds of crafts regarding touch motivation, preference, and product evaluation. A total of 40 subjects are recruited in this study. The independent variables include lighting color temperature (3500 K, 4500 K, and 5500 K) and illuminance (500 lx, 1000 lx, 1500 lx, and 2000 lx), and three different kinds of dependent variables are measured, including motivation to touch, preference, and 10 product evaluation questions, where each is ranked on a five point scale. The experimental results show that a pottery teapot is suitable for 3500 K at 1000 lx and a silver teapot is suitable for 4500 K at 1500 lx, while a color temperature of 5500 K or illuminance of 500 lx produces the lowest touch motivation and preference. The results of multiple regression analysis show that, if the lighting illuminance can improve viewers' preference for the sample or show good touch on the surface, then their touch motivation will be stronger. The findings of this study can provide insight into the motivation of touch, and further provide some guidelines and recommendations regarding display lighting, in order to increase the competitive advantages of works.

这项研究旨在探讨不同色温和照明照度对两种工艺在触摸动机，偏好和产品评估方面的影响。这项研究共招募了40名受试者。自变量包括照明色温（3500 K，4500 K和5500 K）和照度（500 lx，1000 lx，1500 lx和2000 lx），并测量了三种不同的因变量，包括触摸动机，偏好和10个产品评估问题，每个问题以5分制进行评分。实验结果表明，陶瓷茶壶适合于1000 lx的3500 K，而银色茶壶适合于1500 lx的4500 K，而色温为5500 K或照度为500 lx的触摸动机和偏好最低。多元回归分析的结果表明，如果照明照度可以提高观看者对样品的偏爱或在表面上显示出良好的触摸效果，那么他们的触摸动机就会更强。这项研究的发现可以深入了解触摸的动机，并进一步提供一些有关展示照明的准则和建议，以增加作品的竞争优势。
