The tactile sensation is the important factor to judge the hand of textiles. Human can perceive various characteristics of the cloth by a variety of palpate finger motion. However, the finger motion is not clarified yet. If we can know the finger motion, we obtain a high evaluation ability of the hand of cloth. In order to develop the evaluation system for tactile sensation, we should find out the characteristic of finger motion in the perception process of human's hand evaluation. We will be able to get a fundamental data for the evaluation system of the hand. The purpose of our study is to obtain some fundamental data to make the evaluation system to understand the finger motion in the evaluation process of the hand. By pinching the textiles with the thumb and forefinger, and moving the fingers, we evaluate the hand such as softness, smoothness, and so on. We made the glove type system with pressure and acceleration sensors to measure the finger motion. We investigated to understand the characteristics of finger motion in the evaluation of the hand of cloth using the glove type system with pressure sensor. When human evaluate the hand of cloth, they have a special finger motion according to the purpose of evaluation such as resilience, roughness, flexibility and softness. The purpose of this study is to find a special finger motion to satisfy high evaluation ability by comparing the high-level subjects' finger motion and the low-level subjects' motion. We obtained the data such as the applied force measured by the sensor, and analyzed the differences in the finger motion according to the purpose of evaluation and according to the ability of discrimination. As the result, we were able to identify the finger motion between each purpose of evaluation, and conclude that the finger motion varied according to the ability of discrimination. We also conclude that subjects had the characteristic of finger motion when they better understand the purpose of evaluation.
