To summarize, when employing a visual hand rendering overlaying the real hand, participants were more performant and confident in manipulating virtual objects with bare hands in AR.

These results contrast with similar manipulation studies, but in non-immersive, on-screen AR, where the presence of a visual hand rendering was found by participants to improve the usability of the interaction, but not their performance~\cite{blaga2017usability,maisto2017evaluation,meli2018combining}.

This result is in line with the results of virtual object manipulation in VR of \textcite{prachyabrued2014visual}, who found that the most effective visual hand rendering was a double representation of both the real tracked hand and a visual hand physically constrained by the virtual environment.

This type of Skeleton rendering was also the one that provided the best sense of agency (control) in VR~\cite{argelaguet2016role, schwind2018touch}.

These results have of course some limitations as they only address limited types of manipulation tasks and visual hand characteristics, evaluated in a specific OST-AR setup.
