 In a user study, 20 participants rated the coherence, realism and perceived roughness of the combination of nine representative visuo-haptic texture pairs.
 
 The results showed that participants consistently identified and matched clusters of visual and haptic textures with similar perceived roughness.
-The texture rankings did indeed show that participants perceived the roughness of haptic textures to be very similar, but less so for visual textures, and the haptic roughness perception predominated the final roughness perception ranking of the original visuo-haptic pairs.

+Conversely, there was less consensus on the perceived roughness of visual textures.
+Regarding the final roughness perception ranking of the original visuo-haptic pairs, the haptic roughness sensation dominated the perception.
 This suggests that \AR visual textures that augments real surfaces can be enhanced with a set of data-driven vibrotactile haptic textures in a coherent and realistic manner.

 The latter is illustrated in \figref{experiment/use_case}, where a user applies different visuo-haptic textures to a wall, in an interior design scenario, to compare them visually and by touch.
 
 We instinctively perceive the properties of everyday objects by touching and exploring them, but we essentially interact with them by grasping in order to manipulate them.
 In this first part, we focused on the perception of wearable and immersive virtual textures that augment real surfaces when touched with the fingertip.

 We then evaluated the perceived roughness augmentation in these three visual conditions with a psychophysical user study involving 20 participants and extensive questionnaires.

+Similarly, the sensitivity to differences in roughness was better with the real hand, less good with \AR, and in between with \VR.
 Exploration behaviour was also slower in \VR than with real hand alone, although subjective evaluation of the texture was not affected.
 We hypothesised that this difference in perception was due to the \emph{perceived latency} between the finger movements and the different visual, haptic and proprioceptive feedbacks, which were the same in all visual renderings, but were more noticeable in \AR and \VR than without visual augmentation.

+Providing haptic feedback during free-hand manipulation in \AR is not a trivial issue, as wearing haptic devices on the hand might affect the tracking capabilities of the system \cite{pacchierotti2016hring}.
 Moreover, it is important to leave the user capable of interacting with both virtual and real objects, avoiding the use of haptic interfaces that cover the fingertips or palm.
 For this reason, it is often considered beneficial to move the point of application of the haptic feedback elsewhere on the hand (\secref[related_work]{vhar_haptics}).
 However, the impact of the positioning of the haptic feedback on the hand during direct hand manipulation in \AR has not been systematically studied.
 
 Conjointly, a few studies have explored and compared the effects of visual and haptic feedback in tasks involving the manipulation of virtual objects with the hand.
 \textcite{sarac2022perceived} and \textcite{palmer2022haptic} studied the effects of providing haptic feedback about contacts at the fingertips using haptic devices worn at the wrist, testing different mappings.
-Their results proved that moving the haptic feedback away from the point(s) of contact is possible and effective, and that its impact is more significant when the visual feedback is limited.
+Their results proved that moving the haptic feedback away from the point(s) of contact is possible and effective, and that its impact is more significant in the absence of the visual feedback of the virtual hand.
 A final question is whether one or the other of these (haptic or visual) hand feedback should be preferred \cite{maisto2017evaluation,meli2018combining}, or whether a combined visuo-haptic feedback is beneficial for users.
 However, these studies were conducted in non-immersive setups, with a screen displaying the \VE view.
 In fact, both hand feedback can provide sufficient sensory feedback for efficient direct hand manipulation of virtual objects in \AR, or conversely, they can be shown to be complementary.

 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.
