Rendering a stiff virtual surface using a force-feedback haptic interface has been one of the most classic and important research issues in haptics. In this paper, we present an initial study for a novel haptic rendering technique, named stiffness shifting, which greatly increases the perceived hardness of a virtual surface. The key idea of stiffness shifting is to use a stiffness profile that includes an instantaneous increment shortly after a contact. The algorithm is very simple, and can be easily integrated into existing haptic rendering algorithms for 3D objects. Furthermore, the perceptual performance of the algorithm is impressive; a virtual wall rendered using stiffness shifting is perceived as hard as one rendered using the common linear spring model with 2.5 times higher stiffness. This result demonstrates a great potential of stiffness shifting to be a general means for improving the perceptual quality of haptic rendering.
