However, these studies were conducted in non-immersive setups, with a screen displaying the \VE view.
In fact, both hand feedback can provide sufficient sensory feedback for efficient direct hand manipulation of virtual objects in \AR, or conversely, they can be shown to be complementary.
In this chapter, we aim to investigate the role of \textbf{visuo-haptic feedback of the hand when manipulating virtual object} in immersive \OST-\AR using wearable vibrotactile haptics.
In this chapter, we investigate the role of \textbf{visuo-haptic feedback of the hand when manipulating virtual object} using an \OST-\AR headset and wearable vibrotactile haptics.
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}.
