\item The nine visuo-haptic textures used in the user study, selected from the HaTT database \cite{culbertson2014one}.
The texture names were never shown, so as to prevent the use of the user's visual or haptic memory of the textures.
The texture names were never shown, to prevent the use of the user's visual or haptic memory of the textures.
\item Experimental setup.
Participant sat in front of the tangible surfaces, which were augmented with visual textures displayed by the HoloLens~2 \AR headset and haptic roughness textures rendered by the vibrotactile haptic device placed on the middle index phalanx.
A webcam above the surfaces tracked the finger movements.

Participants were instructed to look closely at the details of the visual textures and explore the haptic textures with a constant pressure and various speeds to find the haptic texture that best matched the visual texture, \ie choose the surface with the most coherent visual-haptic texture pair.

The texture names were never given or shown to prevent the use of visual or haptic memory of the textures, nor a definition of what roughness is was given, so as to let participants complete the task as naturally as possible, similarly to Bergmann Tiest \etal \cite{bergmanntiest2007haptic}.

Then, participants performed the \emph{ranking task}, employing the same setup as the matching task and the same 9 textures.
