视觉粗糙度能增强静电布料触觉摩擦感
Pinching Visuo-haptic Display: Investigating Cross-Modal Effects of Visual Textures on Electrostatic Cloth Tactile Sensations
- 结合视觉纹理与静电触觉反馈，模拟虚拟织物抓捏
- 相同电刺激下，视觉越粗糙感知摩擦力越大
- 适合虚拟现实材质交互与多模态界面设计
本文研究视觉纹理呈现如何影响与静电布料显示屏交互时的触觉感知。我们提出一种多模态系统，让用户在抓捏和摩擦虚拟织物时，通过静电驱动感受真实的摩擦力。用户实验表明，在相同电刺激条件下，视觉上更粗糙的纹理会显著增强触觉摩擦力的感知。该结果深化了对多模态纹理感知的理解，为虚拟材料界面中的触觉反馈设计提供了重要指导。
原文摘要 · Abstract (English)
This paper investigates how visual texture presentation influences tactile perception when interacting with electrostatic cloth displays. We propose a visuo-haptic system that allows users to pinch and rub virtual fabrics while feeling realistic frictional sensations modulated by electrostatic actuation. Through a user study, we examined the cross-modal effects between visual roughness and perceived tactile friction. The results demonstrate that visually rough textures amplify the perceived frictional force, even under identical electrostatic stimuli. These findings contribute to the understanding of multimodal texture perception and provide design insights for haptic feedback in virtual material interfaces.
