We propose a two-finger grasping virtual environment that generates realistic vibrations and frictions when the virtual fingers make contact with and slide over virtual objects. By incorporating a precise friction model into the haptic rendering, we reproduced stick-slip vibration more realistically than conventional methods. We will demonstrate how users can experience the grasping operation of virtual objects using the proposed and conventional methods. We use a 6-DOF SPIDAR with a force sensor attached to its rigid gripper as a haptic interface.
