触覚分布提示のための指変形シミュレーションにおける寸法個人差の影響

抄録

Human tactile perception is affected by individual differences in skin shape and material properties. In this study, we report the effects of individual differences in finger size on the strain energy density (SED) distribution in tactile receptors. We created seven finger models with varying widths and thicknesses using statistical data on Japanese finger dimensions. The deformation analysis of the fingers pressing against a rigid plate was conducted using finite element analysis software. The results show that, under the same displacement conditions, the SED distribution in the area between the epidermis and dermis tended to have a smaller maximum value with larger finger thickness. The width of the SED distribution tended to narrow with increasing thickness, and the length tended to lengthen with increasing contact force. However, further verification is needed because the effect of the shape of the finger pad is considered to be significant.
