Haptic rendering based on finite element simulation of vibration

Humans can discriminate materials by tapping objects such as metal and wood. When an object is tapped, some natural vibrations occur accordingly to the structure and the physical properties of the object. Humans perceive the natural vibrations through their tactile receptors and then discriminate between materials. In this study, we propose a haptic vibration rendering method based on a finite element vibration simulation. This method allows to display haptic material feelings using 3D models with different shapes and structures.
