Improving the tactile aesthetics of products that can be described as touch intensive is an increasing priority within many sectors, including the furniture industry. Understanding which physical characteristics contribute to the haptic experience of a surface, and how, is therefore highly topical. It has earlier been shown that both friction and topography affect tactile perception. Thus, two series of stimuli have been produced using standard coating techniques, with systematic variation in (physical) friction and roughness properties. This was achieved through appropriate selection of matting agents and resins. The stimuli sets were then evaluated perceptually to determine the extent to which discrimination between pairs of surfaces followed the systematic materials variation. In addition to investigating the role of the physical properties in discrimination of the surfaces, their influence on perceived pleasantness and naturalness was also studied. The results indicate that changes in tactile perception can be understood in terms of friction and roughness, and that varying the matting agents (topography) and resins (material properties) in the coatings provide the controlling factors for furniture applications. Perceived pleasantness is associated with low friction and smoother topography, whilst perceived naturalness is found to be described by an interaction between tactile friction and the average maximum peak height of the surface features.

处境艰难还是艰难？通过摩擦和地形设计影响木器涂层的触觉感知
在包括家具行业在内的许多行业中，改善可被描述为触摸密集型产品的触觉美感是一个日益重要的优先事项。因此，了解哪些物理特性有助于表面的触觉体验，以及如何产生，是非常热门的话题。早先已经表明，摩擦和地形都会影响触觉。因此，已经使用标准涂层技术产生了两个系列的刺激，在（物理）摩擦和粗糙度特性方面具有系统性变化。This was achieved through appropriate selection of matting agents and resins. 然后在感知上评估刺激集以确定表面对之间的区分程度跟随系统材料变化的程度。除了调查物理特性在表面辨别中的作用外，还研究了它们对感知愉悦度和自然度的影响。结果表明，触觉感知的变化可以通过摩擦和粗糙度来理解，并且涂层中消光剂（形貌）和树脂（材料特性）的变化为家具应用提供了控制因素。感知的愉悦与低摩擦和更平滑的地形有关，而感知的自然性被发现是通过触觉摩擦和表面特征的平均最大峰值高度之间的相互作用来描述的。结果表明，触觉感知的变化可以通过摩擦和粗糙度来理解，并且涂层中消光剂（形貌）和树脂（材料特性）的变化为家具应用提供了控制因素。感知的愉悦与低摩擦和更平滑的地形有关，而感知的自然性被发现是通过触觉摩擦和表面特征的平均最大峰值高度之间的相互作用来描述的。结果表明，触觉感知的变化可以通过摩擦和粗糙度来理解，并且涂层中消光剂（形貌）和树脂（材料特性）的变化为家具应用提供了控制因素。感知的愉悦与低摩擦和更平滑的地形有关，而感知的自然性被发现是通过触觉摩擦和表面特征的平均最大峰值高度之间的相互作用来描述的。
