VRScroll: A Shape-Changing Device for Precise Sketching in Virtual Reality

Studies have shown that incorporating physical surfaces in VR can improve sketching performance by allowing users to feel the contact and rest their pens on it. However, using physical objects or devices to reproduce the diverse shapes of virtual model surfaces can be challenging. We propose VRScroll, a shape-changing device that physically renders the shape of a virtual surface for users to sketch on it using a pen. By providing users with passive haptic feedback and constrained movement, VRScroll has the potential to facilitate precise sketching on virtual surfaces.
