Humans are extraordinarily skilled in the tactile evaluation of, and differentiation between, surfaces. The chemical and mechanical properties of these surfaces are translated into tactile signals during haptic exploration by mechanoreceptors in our skin, which are specialized to respond to different types of temporal and mechanical stimulation. Describing the effects of measurable physical characteristics on the human response to tactile exploration of surfaces is of great interest to manufacturers of household materials so that the haptic experience can be considered during design, product development and quality control. In this study, methods from psychophysics and materials science are combined to advance current understanding of which physical properties affect tactile perception of a range of furniture surfaces, i.e., foils and coatings, thus creating a tactile map of the furniture product landscape. Participants' responses in a similarity scaling task were analyzed using INDSCAL from which three haptic dimensions were identified. Results show that specific roughness parameters, tactile friction and vibrational information, as characterized by a stylus profilometer, a Forceboard, and a biomimetic synthetic finger, are important for tactile differentiation and preferences of these surface treatments. The obtained dimensions are described as distinct combinations of the surface properties characterized, rather than as 'roughness' or 'friction' independently. Preferences by touch were related to the roughness, friction and thermal properties of the surfaces. The results both complement and advance current understanding of how roughness and friction relate to tactile perception of surfaces.

最后一点：摩擦和粗糙度在表面涂层的触觉感知中的作用。

人类在表面的触觉评估和区分方面非常熟练。这些表面的化学和机械特性在我们的皮肤中由机械感受器进行触觉探索时转换为触觉信号，这些感受器专门用于响应不同类型的时间和机械刺激。家用材料制造商对描述可测量的物理特性对人类对表面触觉探索的反应的影响非常感兴趣，因此可以在设计，产品开发和质量控制过程中考虑触觉体验。在这项研究中，结合了心理物理学和材料科学的方法，以加深当前对哪些物理特性会影响一系列家具表面（如箔和涂层）的触觉感知的理解。从而创建家具产品景观的触觉图。使用INDSCAL分析参与者在相似度缩放任务中的响应，从中识别出三个触觉维度。结果表明，以触笔轮廓仪，Forceboard和仿生合成手指为特征的特定粗糙度参数，触觉摩擦和振动信息对于触觉区分和这些表面处理的偏好至关重要。所获得的尺寸被描述为表征的表面性能的不同组合，而不是独立地称为“粗糙度”或“摩擦”。触摸的偏好与表面的粗糙度，摩擦和热性能有关。
