\section{Introduction}
\label{intro}
Touching, grasping and manipulating \VOs are fundamental interactions in \AR (\secref[related_work]{ve_tasks}) and essential for many of its applications (\secref[related_work]{ar_applications}).
The most common current \AR systems, in the form of portable and immersive \OST-\AR headsets \cite{hertel2021taxonomy}, allow real-time hand tracking and direct interaction with \VOs with bare hands (\secref[related_work]{real_virtual_gap}).
Manipulation of \VOs is achieved using a virtual hand interaction technique that represents the user's hand in the \VE and simulates interaction with \VOs (\secref[related_work]{ar_virtual_hands}).
However, direct hand manipulation is still challenging due to the intangibility of the \VE, the lack of mutual occlusion between the hand and the \VO in \OST-\AR (\secref[related_work]{ar_displays}), and the inherent delays between the user's hand and the result of the interaction simulation (\secref[related_work]{ar_virtual_hands}).
