| Research Abstract |
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.
