项目摘要

The purpose of this study is to clarify the influence of the dynamic factors on the recognition of object's hardness by human fingers. In this study, we carried out two kinds of experiment.In the experiment of "judgment of hardness", we examine the relationship between the rate of correct answer and contact force, when each sample A or B is pushed against the palmer right index finger by some conditions making combination of pushing speeds and depths alternately.In the experiment of "evaluation of hardness", we examined the relationship between the subjective evaluation of object's hardness and contact conditions (material of sample, diameter, pushing speed, and depth) of object and human finger.Results of these two experiments are as follows :1) When the material of sample becomes harder, the evaluation of object's hardness increases.2) When the diameter of sample becomes larger, the evaluation of object's hardness increases.3) When the depth of the depression becomes deep, both the rate of correct answer and the evaluation of hardness increase.4) When the pushing speed becomes faster, the rate of correct answer does not change, but the evaluation of hardness increases.From these results, we suggest that not only contact force but also contact conditions affect the recognition of object's hardness by human tactile sense.

本研究的目的是阐明动态因素对人类手指识别物体硬度的影响。在这项研究中，我们进行了两种实验。在“硬度判断”实验中，我们考察了当每个样品A或B被推到手掌右手食指上时，正确答案率与接触力之间的关系。在“硬度评价”实验中，我们考察了物体硬度的主观评价与接触条件（样品材质、直径、推送速度、深度）之间的关系。物体和人的手指。结果这两个实验的结果如下：1）当样品的材质变硬时，物体的硬度评价值增加。2）当样品的直径变大时，物体的硬度评价值增加。3）当凹陷的深度变深时，物体的硬度评价值增加。变深，正确答案率和硬度评价都增加。4）当推动速度变快时，正确答案率没有变化，但硬度评价增加。从这些结果来看，我们建议不仅接触力以及接触条件都会影响物体的识别通过人的触觉来判断硬度。
