Title
NormalTouch and TextureTouch: High-fidelity 3D Haptic Shape Rendering on Handheld Virtual Reality Controllers.
Abstract
We present an investigation of mechanically-actuated hand-held controllers that render the shape of virtual objects through physical shape displacement, enabling users to feel 3D surfaces, textures, and forces that match the visual rendering. We demonstrate two such controllers, NormalTouch and TextureTouch, which are tracked in 3D and produce spatially-registered haptic feedback to a user's finger. NormalTouch haptically renders object surfaces and provides force feedback using a tiltable and extrudable platform. TextureTouch renders the shape of virtual objects including detailed surface structure through a 4×4 matrix of actuated pins. By moving our controllers around while keeping their finger on the actuated platform, users obtain the impression of a much larger 3D shape by cognitively integrating output sensations over time. Our evaluation compares the effectiveness of our controllers with the two de-facto standards in Virtual Reality controllers: device vibration and visual feedback only. We find that haptic feedback significantly increases the accuracy of VR interaction, most effectively by rendering high-fidelity shape output as in the case of our controllers.
