A mobile haptic interface (MHI), a force-feedback haptic interface with a mobile base, allows to render very large virtual objects in a safe and portable manner. In this paper, we present a novel MHI system, featured with: 1) extended horizontal workspace using a omni-directional mobile base, 2) extended vertical workspace using a linear lift, 3) high-accuracy estimation of the position of the haptic...
This article introduces a novel haptization method for rendering surface topography with varying stiffness via a force-feedback haptic interface. Previously, we showed that when surface topography with varying stiffness is rendered with the conventional penalty- based method, topography information perceived by the user can be distorted from its model. This phenomenon was explained by the theory of...
