VRScroll: A Shape-Changing Device for Precise Sketching in Virtual Reality
Studies have shown that a physical surface improves sketching performance in VR by allowing its users to feel the contact and rest their pens on it. However, using physical objects or devices may not be feasible for supporting the diverse shapes of virtual model surfaces.
We propose VRScroll, a shape-changing device that renders the shape of the interacting surface to allow users to precisely sketch on the physical surface with passive haptic feedback and constrained movement. Using seven individually-controlled angle-changing flaps, VRScroll can physically render the surface that simulates the surface of a virtual object. The flaps are covered with a bendable sheet, creating a continuous smooth surface for users to sketch on it using a pen.
Our sketching study showed that participants could trace simple shapes with a pen more precisely when VRScroll was used to provide the physical surface than without VRScroll. The free drawings created by participants using VRScroll were also found to be clearer to crowd evaluators.
