Relief is often used to add patterns to product surfaces, but interaction techniques for modeling relief on the surface of virtual objects have not received due attention. We adopt the repoussé and chasing artwork techniques in an alternative interaction technique for modeling relief on virtual surfaces. To support the interaction technique, we develop a double-sided touchpad called Trampoline that can detect the position and force of a finger touch on both sides. In addition, it provides an elastic feedback to users as the surface consists of an elastic fabric. With this device and the interaction technique developed, we implement a relief application and present modeling results that demonstrate the efficacy of our system.
