A simpler alternative approach is to place a belt under the finger, and to actuate it over 2 \DoFs by two motors placed on top of the finger~\cite{minamizawa2007gravity}.
By turning in opposite directions, the motors shorten the belt and create a sensation of pressure.
Conversely, by turning simultaneously in the same direction, the belt pulls on the skin, creating a shearing sensation.
The simplicity of this approach allows the belt to be placed anywhere on the hand, leaving the fingertip free to interact with the \RE, \eg the hRing on the proximal phalanx in \figref{pezent2019tasbi}~\cite{pacchierotti2016hring} or Tasbi on the wrist in \figref{pezent2019tasbi}~\cite{pezent2019tasbi}.

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}.

\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.
