The occlusion rendering had too much tracking latency to be effective.
This is consistent with similar manipulation studies in \VR and in \VST-\AR setups.
\comans{SJ}{According to the results, occlusion is the most natural (in terms of realism) but least efficient for manipulation. In some cases, natural visualization is necessary. It would be beneficial to discuss these cases to help guide AR interaction designers in choosing the most appropriate visualization methods.}{TODO}
This study suggests that a \ThreeD visual hand augmentation is important in \AR when interacting with a virtual hand technique, particularly when it involves precise finger movements in relation to virtual content, \eg \ThreeD windows, buttons and sliders, or more complex tasks, such as stacking or assembly.

A minimal but detailed rendering of the virtual hand that does not hide the real hand, such as the skeleton rendering we evaluated, seems to be the best compromise between the richness and effectiveness of the feedback.
%Still, users should be able to choose and adapt the visual hand augmentation to their preferences and needs.

In addition to visual augmentation of the hand, direct manipulation of virtual objects with the hand can also benefit from wearable haptic feedback.
In the next chapter, we explore two wearable vibrotactile contact feedback devices in a user study, located at four positionings on the hand so as to not cover the fingertips.
