Robotic touch surface: 3D haptic rendering of virtual geometry on touch surface

Abstract

In this demonstration, we propose a robotic haptic surface display that physically imitates the orientation of virtual 3D geometry at the point of touch. The proposed system mechanically aligns its display surface with virtual 3D geometry. This allows users to obtain tactual information where contact takes place. The proposed haptic rendering scheme is built on the basic consideration that relative tactual experiences play a significant role in haptic object perception.
