KinesTouch: 3D Force-Feedback Rendering for Tactile Surfaces
2018
In this paper, we introduce the KinesTouch, a novel approach for tactile screen enhancement providing four types of haptic feedback with a single force-feedback device: compliance, friction, fine roughness, and shape. We present the design and implementation of a corresponding set of haptic effects as well as a proof-of-concept setup. Regarding friction in particular, we propose a novel effect based on large lateral motion that increases or diminishes the sliding velocity between the finger and the screen. A user study was conducted on this effect to confirm its ability to produce distinct sliding sensations. Visual cues were confirmed to influence sliding judgments, but further studies would help clarifying the role of tactile cues. Finally, we showcase several use cases illustrating the possibilities offered by the KinesTouch to enhance 2D and 3D interactions on tactile screens in various contexts.
