Many robotics applications involving contact with objects require the decomposition of an external force measured by a force sensor into its normal and shear components. In this paper, we present a general and effective contact force decomposition method based on the contact pressure distribution. The contact pressure distribution can be measured easily using recently developed flexible pressure sensor...
Haptic rendering of soft objects is an essential component for medical haptic applications. In this paper we follow a data-driven haptic rendering approach, which generates haptic feedback based on recorded signals for high fidelity rendering. This paper introduces a new data-driven haptic rendering framework that can especially generates a model and renders frictional sliding contact with a deformable...
This paper proposes a contact force decomposition method using tactile information for haptic augmented reality (AR). Haptic AR modulates real haptic interaction to desired interaction by adding virtual haptic feedback. For haptic AR rendering, the measurement of real haptic interaction including deformation and friction force is important for accurate rendering, but the current haptic AR algorithms...
Haptic augmented reality merges real and virtual feedback, allowing a user to touch the real environment augmented with virtual haptic stimuli. A key functionality of this technology is altering the haptic properties of real objects by means of virtual haptic feedback. Previously, we have developed a haptic augmentation system in which object stiffness was modulated. In this paper, we extend our framework...
