The haptic textures used were captures and models of the vibrations of a hand-held probe sliding over real surfaces.
We generated the vibrotactile textures only from the finger speed \cite{culbertson2015should}, but the perceived roughness of real textures also depends on other factors, such as the contact force, the angle, the posture or the surface of the contact \cite{schafer2017transfer}, but their respective importance in the perception is not yet fully understood \cite{richardson2022learning}.
It would be interesting to determine the importance of these factors on the perceived realism of virtual vibrotactile textures.
The virtual texture models should also be adaptable to individual sensitivities \cite{malvezzi2021design,young2020compensating}.
We also rendered haptic textures captured from a hand-held probe to be touched with the bare finger, but finger based captures of real textures should be considered as well \cite{balasubramanian2024sens3}.
Finally, the virtual texture models should also be adaptable to individual sensitivities \cite{malvezzi2021design,young2020compensating}.

Some users found the vibration rendering to be too strong, suggesting that adapting and personalizing the haptic feedback to one's preference is to investigate \cite{malvezzi2021design, umair2021exploring}.

In addition, although it was perceived as more effective and realistic when provided close to the point of contact, other positionings, such as the wrist, may be preferred and still be sufficient for a given task.
The interactions in our user study were also restricted to the thumb and index fingertips, with the haptic feedback provided only for these contact points, as these are the most commonly used parts of the hand for manipulation tasks.
It remains to be explored how to support rendering for different and larger areas of the hand, and how to position a delocalized rendering for points other than the fingertips could be challenging.
