The computation of skin forces and deformations for\ tactilerendering\ requires an accurate model of the extremely\ nonlinear\ behavior of the skin. In this work, we investigate the\ characterization\ of\ fingermechanics\ with the goal of designing accurate\ nonlinear\ models for\ tactilerendering. First, we describe a measurement setup that enables the acquisition of contact force and contact area in the context of controlled\ finger\ indentation experiments. Second, we describe an optimization procedure that estimates the parameters of strain-limiting deformation models that match best the acquired data. We show that the acquisition setup allows the measurement of force and area information with high repeatability, and the estimation method reaches\ nonlinear\ models that match the measured data with high accuracy.
