提出了一种新的触觉评价方法。虽然触觉是最终用户评价产品的重要信息，但尚未定量表征。为了实现触觉的定量表征，本文开发了一种基于人体触觉感知机制的触觉评价系统。在该系统中，将被评估的物体固定在以恒定速度旋转的样品台上，并以恒定的法向力将压电元件放置在与物体表面接触的位置。然后利用压电元件测量实验过程中的振动信息。将振动信息与触觉感受器的特性进行比较，可以估计我们在主动触摸物体时所获得的信息。将感官评价结果与估计信息进行比较，定义了目标物体的柔软度、粗糙度和偏好度三个触觉评价指标。(C) 2013 Elsevier By。版权所有。
This paper presents a novel tactile evaluation method. Although tactile sense is important information for end users to evaluate products, it has not been characterized quantitatively. In order to achieve quantitative characterization of tactile sense, this paper develops a novel tactile evaluation system based on human tactile perception mechanism. In the system, an object, which will be evaluated, is fixed on a sample table rotated with constant speed, and a piezoelectric element is placed in contact with the object surface with constant normal force. Then the piezoelectric element measures the vibration information during experiment. Comparing the vibration information with tactile receptors properties, we could estimate information we are getting during actively touching the object. Comparing the sensory evaluation results with the estimated information, the paper defines three tactile evaluation indexes relating to softness, roughness and preference of the target object.
