\subsection{Modifying Perceived Haptic Roughness and Hardness}
\label{tactile_rendering}
Tactile rendering of haptic properties consists in modelling and reproducing virtual tactile sensations comparable to those perceived when interacting with real objects.
By adding such tactile rendering as feedback to the touch actions of the hand on a real object~\cite{bhatia2024augmenting}, both the real and virtual haptic sensations are integrated into a single property perception~\cite{ernst2004merging}.
Tactile rendering of haptic properties consists in modelling and reproducing virtual tactile sensations comparable to those perceived when interacting with real objects~\cite{klatzky2013haptic}.
By adding such tactile rendering as feedback to the touch actions of the hand on a real object~\cite{bhatia2024augmenting}, both the real and virtual haptic sensations are integrated into a single property perception, as presented in \secref{sensations_perception}.
Therefore, the visual rendering of a touched object can also greatly influence the perception of its haptic properties, \eg by modifying its visual texture in \AR or \VR, as discussed in the \secref{visuo_haptic}.
\textcite{bhatia2024augmenting} categorize the tactile augmentations of real objects into three types: direct touch, touch-through, and tool mediated.
In direct touch, the haptic device does not cover the interior of the hand to not impair the user to interact with the \RE.
Also called direct feel-through~\cite{jeon2015haptic}, in \emph{direct touch}, the haptic device does not cover the interior of the hand to not impair the user to interact with the \RE.
In touch-through and tool-mediated, or \emph{indirect feel-through}, the haptic device is interposed between the hand and the \RE or worn on the hand, respectively.
We are interested in direct touch augmentations with wearable haptic devices (\secref{wearable_haptic_devices}), as their integration with \AR is particularly promising for direct hand interaction with visuo-haptic augmentations.
We also focus tactile augmentations stimulating the mechanoreceptors of the skin (\secref{haptic_sense}), thus excluding temperature perception, as they are the most common existing haptic interfaces.
