(center) The haptic wheels are interchangeable and can be customized to render arbitrary textures, shapes, or interactive elements. (right) Wheel features are spatially registered with the virtual environment, so the user can reach out and feel virtual surfaces.<\/p><\/div>\n<p>We present Haptic Revolver, also known as the Haptic Wheel, a handheld virtual reality controller that renders fingertip haptics when interacting with\u00a0virtual surfaces. Haptic Revolver\u2019s core haptic element is an actuated wheel that raises and lowers underneath the finger to render contact with a virtual surface. As the user\u2019s 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.<\/p>\n\t<iframe\n\t\tsrc=\"https:\/\/www.youtube.com\/embed\/5sRKh3rPzyA?rel=0\"\n\t\twidth=\"560\"\n\t\theight=\"315\"\n\t\taria-label=\"\"\n\t\tallowfullscreen=\"true\">\n\t<\/iframe>\n\t\n","protected":false},"excerpt":{"rendered":"<p>We present Haptic Revolver, also known as the Haptic Wheel, a handheld virtual reality controller that renders fingertip haptics when interacting with\u00a0virtual surfaces.
