These texture models were chosen as they are visuo-haptic representations of a wide range of real textures that are publicly available online.

Nine texture pairs were selected (see \figref{setup}, left) to cover various perceived roughness, from rough to smooth, as listed: Metal Mesh, Sandpaper~100, Brick~2, Cork, Sandpaper~320, Velcro Hooks, Plastic Mesh~1, Terra Cotta, Coffee Filter.

All these visual and haptic textures are isotropic: their rendering (appearance or roughness) is the same whatever the direction of the movement on the surface, \ie there are no local deformations (holes, bumps, or breaks).

When a haptic texture was touched, a \qty{48}{kHz} audio signal was generated using the corresponding HaTT haptic texture model and the measured tangential speed of the finger, using the rendering procedure described in Culbertson \etal~\cite{culbertson2014modeling}.
