\section{Vibrotactile Renderings of the Hand-Object Contacts}
\label{vibration}
The vibrotactile hand rendering provided information about the contacts between the \VO and the thumb and index fingers of the user, as they are the two fingers most used for grasping (\secref[related_work]{grasp_types}).
The vibrotactile hand rendering provided information about the contacts between the virtual object and the thumb and index fingers of the user, as they are the two fingers most used for grasping (\secref[related_work]{grasp_types}).
We evaluated both the delocalized positioning and the contact vibration technique of the vibrotactile hand rendering.
\subsection{Vibrotactile Positionings}
\label{positioning}
We considered five different positionings for providing the vibrotactile rendering as feedback of the contacts between the virtual hand and the \VOs, as shown in \figref{method/locations}.

They are representative of the most common locations used by wearable haptic devices in \AR to place their end-effector, as found in the literature (\secref[related_work]{vhar_haptics}), as well as other positionings that have been employed for manipulation tasks.
For each positioning, we used two vibrating actuators, for the thumb and index finger, respectively.

\section{User Study}
\label{method}
This user study aims to evaluate whether a visuo-haptic rendering of the hand affects the user performance and experience of manipulation of \VOs with bare hands in \OST-\AR.
This user study aims to evaluate whether a visuo-haptic rendering of the hand affects the user performance and experience of manipulation of virtual objects with bare hands in \OST-\AR.
The chosen visuo-haptic hand renderings are the combination of the two most representative visual hand renderings established in the \chapref{visual_hand}, \ie \level{Skeleton} and \level{No Hand}, described in \secref[visual_hand]{hands}, with the two contact vibration techniques provided at the four delocalized positions on the hand described in \secref{vibration}.
