Building a navigable fine texture design space
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
