The visual hand augmentation was perceived less necessary than the vibrotactile haptic feedback, but still provided a useful feedback on the hand tracking.
This study provide evidence that moving away the feedback from the inside of the hand is a simple but promising approach for wearable haptics in \AR.

If integration with the hand tracking system allows it, and if the task requires it, a haptic ring worn on the middle or proximal phalanx seems preferable.
However, a wrist-mounted haptic device will be able to provide richer feedback by embedding more diverse haptic actuators with larger bandwidths and maximum amplitudes, while being less obtrusive than a ring.
Finally, we think that the visual hand augmentation complements the haptic contact rendering well by providing continuous feedback on the hand tracking, and that it can be disabled during the grasping phase to avoid redundancy with the haptic feedback of the contact with the virtual object.
It can provide more realistic and appreciated feedback, being closer to the point of contact.
However, a calibration step seems important to adapt to the individual preferences and sensitivities of the user.
Yet, a wrist-mounted haptic device will be able to provide richer feedback by embedding more diverse haptic actuators with larger bandwidths and maximum amplitudes, while being less obtrusive than a ring.
It could thus provide more complex feedback of the contacts with the virtual objects.
