Abstract
Measuring the shear deformation of finger pads during the tracing movement is important for analysis of tactile sensations and development of tactile texture displays. We have been developing a new method to estimate the finger pad's deformation based on the deformation propagated to the radial side of finger tip. In this study, in order to validate the method, we compared the accelerations of finger pad estimated based on the deformation of radial side and those by the shear forces applied to the finger pad while exploring a few types of materials. A mean error between the accelerations estimated by the two methods was merely 2.9 × 10^<-3> m/s^2.
