The textures were perceived as \textbf{rougher when touched with the real hand alone compared to a virtual hand} in either \AR or \VR, possibly due to the \textbf{perceived latency} between finger movements and different visual, haptic, and proprioceptive feedbacks.
In \chapref{vhar_textures}, we investigated the perception of co-localized visual and wearable haptic texture augmentations on tangible surfaces.
We transposed the \textbf{data-driven visuo-haptic textures} from the \HaTT database to the system presented in \chapref{vhar_system} and conducted a user study with 20 participants to rate the coherence, realism, and perceived roughness of nine visuo-haptic texture pairs.
We transposed the \textbf{data-driven visuo-haptic textures} from the \HaTT database to the system presented in \chapref{vhar_system} and conducted a user study with 20 participants to rate the coherence, realism, and perceived roughness of the combination of nine visuo-haptic texture pairs.
Participants integrated roughness sensations from both visual and haptic modalities well, with \textbf{haptics predominating the perception}, and consistently identified and matched \textbf{clusters of visual and haptic textures with similar perceived roughness}.
\noindentskip In \partref{manipulation} we focused on improving the manipulation of \VOs directly with the hand in immersive \OST-\AR.
