opposed to the relative velocity between the contacting points on both surfaces.<br />

In order to extend the use of the present contact model for simulation of grasping with<br />

the whole hand, experimental data relating force with displacement and force with<br />

contact area for different points of the palmar aspect of the hand would be necessary.<br />

Future work is being addressed to obtain this data. Another question of interest to be<br />

studied is the effect of the object curvature in the value of the optimized parameters of<br />

the model. The adjusted soft contact model will be included in the future in a<br />

biomechanical model of the hand previously developed in our group [15] and tested in<br />

different simple grasping scenarios to evaluate its suitability to evaluate human grasp<br />

performance.<br />
