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.
In our system, we registered the \RE and the \VE using fiducial markers and a webcam external to the \AR headset.
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 HoloLens~2 were not able to track hands wearing a vibrotactile voice-coil device.
A more robust hand pose estimation system would support wearing haptic devices on the hand as well as holding real objects.

Haptic feedback should be provided close to the point of contact of the hand with the virtual, to enhance the realism of texture augmentation (\chapref{vhar_textures}) and to render contact with virtual objects (\chapref{visuo_haptic_hand}), \eg rendering fingertip contact with a haptic ring worn on the middle or proximal phalanx.
However, the task at hand, the user's sensitivity and preferences, the limitations of the tracking system, or the ergonomics of the haptic device may require the use of other form factors and positions, such as the wrist or arm.
Similarly, collaborative and transitional experiences between \AR and \VR are becoming more common, and would involve different setups and modalities \cite{roo2017onea}.
Novel \AR/\VR displays are already capable of transitioning from augmented to virtual environments \cite{feld2024simple}, and haptic feedback should also adapt to these transitions (\chapref{xr_perception}).
Novel \AR/\VR displays are already capable of transitioning from \AE to \VE \cite{feld2024simple}, and haptic feedback should also adapt to these transitions (\chapref{xr_perception}).
Therefore, a visuo-haptic augmented reality system should be able to adapt to any \AR/\VR display, any wearable haptic device worn anywhere on the body, and support personalization of haptic feedback.
In other words, the visuo-haptic rendering system should be designed to be responsive to the context of use.
