However, these studies were conducted in non-immersive setups, with a screen displaying the \VE view.
In fact, both hand renderings can provide sufficient sensory feedback for efficient direct hand manipulation of \VOs in \AR, or conversely, they can be shown to be complementary.
In this chapter, we aim to investigate the role of \textbf{visuo-haptic rendering of the hand manipulation} with \VOs in immersive \OST-\AR using wearable vibrotactile haptics.
We selected \textbf{four different delocalized positionings} that have been previously proposed in the literature for direct hand interaction in \AR using wearable haptic devices (\secref[related_work]{vhar_haptics}): on the nails, the proximal phalanges, the wrist, and the nails of the opposite hand.

We selected \textbf{four different delocalized positionings on the hand} that have been previously proposed in the literature for direct hand interaction in \AR using wearable haptic devices (\secref[related_work]{vhar_haptics}): on the nails, the proximal phalanges, the wrist, and the nails of the opposite hand.
We focused on vibrotactile feedback, as it is used in most of the wearable haptic devices and has the lowest encumbrance.
In a \textbf{user study}, using the \OST-\AR headset Microsoft HoloLens~2 and two \ERM vibrotactile motors, we evaluated the effect of the four positionings with \textbf{two contact vibration techniques} on the user performance and experience with the same two manipulation tasks as in \chapref{visual_hand}.
We additionally compared these vibrotactile renderings with the \textbf{skeleton-like visual hand rendering} established in the \chapref{visual_hand} as a complementary visuo-haptic feedback of the hand interaction with the \VOs.

\section{Conclusion}
\label{conclusion}
In this chapter, we investigated the visuo-haptic rendering as feedback of the hand manipulation with \VOs in immersive \OST-\AR using wearable vibrotactile haptic.
In this chapter, we investigated the visuo-haptic rendering as feedback of the direct hand manipulation with \VOs in immersive \OST-\AR using wearable vibrotactile haptic.
To do so, we provided vibrotactile feedback of the fingertip contacts with \VOs during direct hand manipulation by moving away the haptic actuator that do not cover the inside of the hand: on the nails, the proximal phalanges, the wrist, and the nails of the opposite hand.
%We selected these four different delocalized positions on the hand from the literature for direct hand interaction in \AR using wearable haptic devices.
In a user study, we compared sixteen visuo-haptic renderings of the hand as the combination of two vibrotactile contact techniques, provided at four different delocalized positions on the user's hand, and with the two most representative visual hand renderings established in the \chapref{visual_hand}, \ie the skeleton hand rendering and no hand rendering.
