Friction modulation technology enables the creation of textural effects on flat haptic displays. However, an intuitive and manageably small design space for construction of such haptic textures remains an unfulfilled goal for user interface designers. In this paper, we explore perceptually relevant features of fine texture for use in texture construction and modification. Beginning with simple sinusoidal patterns of friction force that vary in frequency and amplitude, we define irregularity, essentially a variable amount of introduced noise, as a third building block of a texture pattern. We demonstrate using multidimensional scaling that all three parameters are scalable features perceptually distinct from each other. Additionally, participants' verbal descriptions of this 3-dimensional design space provide insight into their intuitive interpretation of the physical parameter changes.
摩擦调制技术能够在平面触觉显示器上创建纹理效果。然而，为构建此类触觉纹理而设计一个直观且易于管理的小设计空间，对于用户界面设计师来说仍是一个未实现的目标。在本文中，我们探索了用于纹理构建和修改的精细纹理的感知相关特征。从摩擦力随频率和幅度变化的简单正弦模式开始，我们将不规则性（本质上是引入的可变噪声量）定义为纹理模式的第三个构建要素。我们使用多维缩放证明，所有这三个参数都是在感知上彼此不同的可扩展特征。此外，参与者对这个三维设计空间的口头描述提供了他们对物理参数变化的直观解释的见解。
