\subsection{Tactile Renderings for Modifying Object Properties}
\label{tactile_rendering}
Le rendu tactile des propriétés haptiques consiste à modéliser et reproduire des sensations cutanées virtuelles comparables à celles perçues lors de l'interaction avec des objets réels.
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}.
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_ar}.
En particulier, nous nous intéressons aux actuateurs portables stimulant les méchano-récepteurs de la peau (voir \secref{haptic_sense}) et n'empêchant pas de toucher et interagir avec l'environnement réel et aux rendus de propriétés haptiques d'objets virtuels ou augmentés.
\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.
We are interested in direct touch augmentations with wearable haptic devices (see \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 (see \secref{haptic_sense}), thus excluding temperature perception, as they are the most common existing haptic interfaces.
In the context of integrating \WHs with \AR to create a \vh-\AE (see \chapref{introduction}), the definition of \textcite{pacchierotti2017wearable} can be extended to an additional criterion: The wearable haptic interface should not impair the interaction with the \RE, \ie the user should be able to touch and manipulate objects in the real world while wearing the haptic device.
