In haptically enabled virtual reality, most existing devices render kinesthetic feedback via one 3DoF single-contact-point, thus they cannot stimulate tactily teh fingertip skin. This lack of information prevents the perception of contact surface orientation in absence of vision and of free exploratory movements. In this work we experimentally investigate the rendering performance of a contact model which exploits anisotropic contact stiffness to convey such information.
