Haptic Revolver: Touch, Shear, Texture, and Shape Rendering on a Reconfigurable Virtual Reality Controller


論文アブストラクト:We present Haptic Revolver, a handheld virtual reality controller that renders fingertip haptics when interacting with virtual surfaces. Haptic Revolver's core haptic element is an actuated wheel that raises and lowers underneath the finger to render contact with a virtual surface. As the user's finger moves along the surface of an object, the controller spins the wheel to render shear forces and motion under the fingertip. The wheel is interchangeable and can contain physical textures, shapes, edges, or active elements to provide different sensations to the user. Because the controller is spatially tracked, these physical features can be spatially registered with the geometry of the virtual environment and rendered on-demand. We evaluated Haptic Revolver in two studies to understand how wheel speed and direction impact perceived realism. We also report qualitative feedback from users who explored three application scenarios with our controller.


VR空間内で指先が仮想物体に触れると,デバイスの先端についた交換可能なホイールが,左右に回転して各仮想物体に適した触覚提示を行うコントローラを開発した. ユーザ評価から,振動による触覚提示よりも現実感があることを確認した.
