The concept of inverse perlin noise for tactile rendering

This paper proposes the concept of inverse perlin noise which is a reverse process of perlin noise. The proposed method enables users to feel the haptic sensation when he/she rubs on the surface of an object. We extract individual random signals from a target object modeled by perlin noise and apply them to haptic actuators. In order to evaluate the proposed method, we compute errors between the original perlin noise and the reconstructed noise function obtained from the inverse perlin noise. Through the experiment, we verify that the proposed method has enough possibility to be applied in tactile rendering.
