Results showed that delocalized vibrotactile haptic hand rendering improved the perceived effectiveness, realism, and usefulness when it is provided close to the contact point.
%However, the farthest positioning on the contralateral hand gave the best performance even though it was disliked: the unfamiliarity of the positioning probably caused the participants to take more effort to consider the haptic stimuli and to focus more on the task.
The visual hand rendering was perceived less necessary than the vibrotactile haptic hand rendering, 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 very 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 rendering complements the haptic hand rendering very 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 \VO.
