   \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.
