Abstract
We describe experiments that compared the perceived relative roughness of textured virtual walls synthesized with an accurately controlled haptic interface. Texture was modeled as a spatially modulated sinusoidal friction grating. The results indicate that both the modulation depth of the grating (A), and the coefficient of friction (μ) are strongly associated with the perceived roughness when increasing either A or μ. Changing the spatial period of the grating (l), however, did not yield consistent relative roughness judgement results, indicating that there is a weaker association.
