Building a navigable fine texture design space
This addresses a need for user interface designers to construct and modify haptic textures more effectively, though it appears incremental in building upon existing friction modulation technology.
The paper tackled the problem of creating an intuitive and manageable design space for haptic textures on flat displays by exploring perceptually relevant features like frequency, amplitude, and irregularity, showing irregularity as a scalable and distinct feature through multidimensional scaling.
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 as a third building block of a texture pattern and show it to be a scalable feature distinct from the others using multidimensional scaling. Additionally, subjects' verbal descriptions of this 3-dimensional design space provide insight into their intuitive interpretation of the physical parameter changes.
