\paragraph{Fully Integrated Tracking.}
In our system, we registered the real and virtual environments (\secref[related_work]{ar_definition}) using fiducial markers and a webcam external to the \AR headset.
This only allowed us to track the index finger and the surface to be augmented with the haptic texture, but the tracking was reliable and accurate enough for our needs.
This only allowed us to estimate poses of the index finger and the surface to be augmented with the haptic texture, but it was reliable and accurate enough for our needs.
In fact, preliminary tests we conducted showed that the built-in tracking capabilities of the Microsoft HoloLens~2 were not able to track hands wearing a vibrotactile voice-coil device.
A more robust hand tracking system would support wearing haptic devices on the hand as well as holding real objects.
A more robust hand pose estimation system would support wearing haptic devices on the hand as well as holding real objects.
A complementary solution would be to embed tracking sensors in the wearable haptic devices, such as an inertial measurement unit (IMU) or cameras \cite{preechayasomboon2021haplets}.
Prediction of hand movements should also be considered \cite{klein2020predicting,gamage2021predictable}.
This would allow a complete portable and wearable visuo-haptic system to be used in practical applications.

We purposely chose this type of display because in \OST-\AR the lack of mutual occlusion between the hand and the virtual object is the most challenging to solve \cite{macedo2023occlusion}.
We therefore hypothesized that a visual hand augmentation would be more beneficial to users with this type of display.
However, the user's visual perception and experience are different with other types of displays, such as \VST-\AR, where the \RE view is seen through cameras and screens (\secref[related_work]{ar_displays}).
While the mutual occlusion problem and the hand tracking latency could be overcome with \VST-\AR, the visual hand augmentation could still be beneficial to users as it provides depth cues and feedback on the hand tracking, and should be evaluated as such.
