         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.

         The visual texture overlays are statically displayed on the surfaces, allowing the user to move around to view them from different angles. %
         The haptic roughness texture is generated based on HaTT data-driven texture models and finger speed, and it is rendered on the middle index phalanx as it slides on the considered surface.%
