 \paragraph{Other AR Displays}
 
 The visual hand renderings we evaluated were displayed on the Microsoft HoloLens~2, which is a common \OST-\AR headset.
+We purposely chose this type of display as it is with \OST-\AR that the lack of mutual occlusion between the hand and the \VO is the most challenging to solve \cite{macedo2023occlusion}.
+We thus hypothesized that a visual hand rendering would be more beneficial to users with this type of display.
+However, the user's visual perception and experience is very different with other types of displays, such as \VST-\AR, where the \RE view is seen through a screen (\secref[related_work]{ar_displays}).
+While the mutual occlusion problem and the hand tracking latency can be overcome with \VST-\AR, the visual hand rendering could still be beneficial to users as it provides depth cues and feedback on the hand tracking, and should be evaluated as such.
 
 \paragraph{More Ecological Conditions}
 
-We evaluated the effect of the visual hand rendering with two manipulation tasks involving to place a virtual cube into a target volume either by pushing it on a table or by grasping it.
-%While these tasks are fundamental and basics
-
-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.
-The two manipulation tasks were also limited to placing a virtual cube in predefined target volumes.
-Testing a wider range of virtual objects and more ecological tasks \eg stacking, assembly, will ensure a greater applicability of the results obtained in this work, as well as considering bimanual manipulation.
-Similarly, a broader experimental study might shed light on the role of gender and age, as our subject pool was not sufficiently diverse in this respect.
-However, we believe that the results presented here provide a rather interesting overview of the most promising approaches in \AR manipulation.
+We conducted the user study with two manipulation tasks that involved placing a virtual cube in a target volume, either by pushing it on a table or by grasping and lifting it.
+While these tasks are fundamental building blocks for more complex manipulation tasks \cite{laviolajr20173d}, such as stacking or assembly, more ecological uses should be considered.
+Similarly, a broader experimental study might shed light on the role of gender and age, as our subject pool was not sufficiently diverse in this regard.
+Finally, all visual hand renderings received low and high rank rates from different participants, suggesting that users should be able to choose and personalize some aspects of the visual hand rendering according to their preferences or needs, and this should be also be evaluated.
