2A1-A11 TAKO-Pen : Pen-Type Pseudo-Haptic Interface Using Suction Pressure on the Skin Second Report : Deformation Analysis of Finger-pad in Holding a Pen Applied with External Force(Tactile and Force Sensing (1))

Abstract

We have developed the TAKO-Pen, a pen-type pseudo-haptic interface using suction pressure stimulation on the skin. This paper presents a follow up report to support the results obtained in an earlier study. In this paper, we obtain an analysis on the finger pad deformation using the finite element method. The analysis was based on the grasping condition of the finger on the pen at which external force is applied. This analysis is important for developing the guidelines for controlling pressure distribution on the skin. We found that strain energy density appears to conform to the responses we had obtained in the psychophysical experiment.
