Abstract-In three experiments, viscosity perception of liquids using the sense of touch was studied. The first two were discrimination experiments in which Weber fractions were determined for a number of viscosities spanning the range of what is encountered in daily life, and for two ways of perceiving viscosity (stirring with a spatula or with the index finger). For high viscosities, Weber fractions were around 0.3, whereas they increased for lower viscosities. For low viscosities, discrimination performance was much worse with the finger than with the spatula. In the third experiment, subjects matched liquids perceived with these two methods, which resulted in biases of around 80 %. Control experiments and force measurements were performed to find an explanation for these results. It was concluded that the relationship between perceived and physical viscosity is steeper for stirring liquids with a spatula than stirring with the finger.

“…Moving a tool through regolith, in contrast to fluid, not only deforms, but also compacts the regolith, changing its material properties. Recent work shows that even when rendering only characteristic properties such as viscosity [4], or inertia [5], [6], users can perceive media to be convincingly fluid. This begs the question: could a simplified model suffice for regolith interaction?…”

Driven by the need for physically accurate and haptically convincing models of lunar and planetary regolith for model-mediated teleoperation in space, we present an approach to modelling regolith in an efficient yet realistic way. Model parameters are derived from physical characteristics of the regolith, to render regoliths with different density profiles, cohesion, internal friction and in different gravitational fields.Users could distinguish between changes in parametersspecifically friction and gravity field-and also gave qualitative feedback relevant to modelling regolith. We discuss the challenges in haptically rendering soils and the next steps.
