정전기 마찰 진동으로 렌더링한 질감의 인지 공간

MasterIn this thesis, we obtained a perceptual space of regular tessellation textures rendered by electrovibration as the first step research for applying electrovibration to in-vehicle touch pads. We suggested design parameters for generating regular tessellations and generated 32 textures. We measured the dissimilarity between the textures and applied 3D nonmetric classical multidimensional scaling to the dissimilarity scores and investigated the characteristics of the space by adjective rating. The major factors that increased the perceptual distance were the maximum frictional force $f$ and the thickness of edges $e$ of the tessellation. Rough-Smooth pair was highly correlated to the perceptual space. The perceptual space could help haptic designers to understand the relationship of the electrovibration-rendered regular tessellation textures and the perceptual distances between the textures
