In this study, we aim to reproduce the friction sensation felt when tracing an object with a fingertip by modeling the skin vibrations that occur when touching the object. We focus on stick-slip vibration as the target of the vibration to be modeled. In order to model the stick-slip vibration according to the normal force and velocity of the fingertip, we constructed a device to simultaneously measure the skin vibration, normal force and tangential force, and conducted measurement experiments. From the measured vibration waveforms, we extracted the feature values that characterize the vibration and analyzed the relationship between the normal force and the tracing speed. A model of the maximum amplitude of the vibration was constructed from the obtained results. The model of the maximum amplitude was found to be highly accurate under several conditions.
