本研究提出一种虚拟实境的触感显示器，以呈现衣服细微的触感。该设备使用柔软的高分子凝胶致动器开发，可以表达衣服的触感的微妙差异，特别是粗糙的材料，如毛巾和牛仔布。考虑到视觉在多通道感知中的优势，提出了一种融合视觉信息的虚拟触感显示器，更好地表达了织物的真实的触感。为了定量评估视觉信息添加到触觉的影响，使用形容词对量表进行因子分析。对真实的材料的因子分析表明，粗糙度因子与视觉感受高度相关，而柔软度因子与图像信息相对独立。同样的分析应用于人工触觉，显示出更复杂的结果。结果表明，只有当视觉信息能很好地表达材料的特性时，视觉才能帮助触觉的识别，但当视觉信息不合适时，视觉也会误导触觉感知。通过应用与人工触觉不同的错误视觉信息，评价视觉信息的优越性。
This study presents a tactile feel display of virtual reality for subtle fine touch of clothes. The device developed using soft high polymer gel actuators could express subtle differences of touch of clothes, especially rough materials such as a towel and denim. Considering the superiority of vision in the multimodal sensational perception, a virtual tactile feel display integrated with visual information which express more real touch of cloth was proposed. In order to evaluate the influence of visual information adding to the tactile feel quantitatively, a factor analysis was performed using adjective pair scales. Factor analysis applied to the real materials showed that the roughness factor is highly correlated with the visual sensation although the softness factor is relatively independent from image information. The same analysis applied to the artificial tactile feel showed more complex results. It was confirmed that vision could help the recognition of tactile feel only when the characteristics of the material was expressed well by visual information although could also mislead tactile perception when visual information was not appropriate. The superiority of visual information was also evaluated by applying wrong visual information different from the artificial tactile feels.
