Tactile displays based on friction modulation offer wide-bandwidth forces rendered directly on the fingertip. However, due to a number of touch conditions (e.g., normal force, skin hydration) that result in variations in the friction force and the strength of modulation effect, the precision of the force rendering remains limited. In this paper we demonstrate a closed-loop electroadhesion method for precise playback of friction force profiles on a human finger and we apply this method to the tactile rendering of several textiles encountered in everyday life.
基于摩擦调制的触觉显示器可在指尖直接呈现宽带力。然而，由于多种触摸条件（如法向力、皮肤湿度）会导致摩擦力和调制效果强度发生变化，力呈现的精度仍然有限。在本文中，我们展示了一种用于在人手指上精确回放摩擦力分布的闭环电粘附方法，并将此方法应用于日常生活中几种纺织品的触觉呈现。
