 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.
+The texture rankings did indeed show that participants perceived the roughness of haptic textures to be very similar.
+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.
 
-This paves the way for new \AR applications capable of augmenting a \RE with virtual visuo-haptic textures, such as visuo-haptic painting in artistic or object design context, or viewing and touching virtual objects in a museum or a showroom.
+This paves the way for new \AR applications capable of augmenting a real environment with virtual visuo-haptic textures, such as visuo-haptic painting in artistic or object design context, or viewing and touching virtual objects in a museum or a showroom.
 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.
-In the next part, we improve the direct manipulation with the hand of virtual object with wearable visuo-haptic interaction feedback.

 We then evaluated the perceived roughness augmentation in these three visual conditions with a psychophysical user study involving 20 participants and extensive questionnaires.
 
 Our results showed that the visual virtuality of the hand (real or virtual) and the environment (\AR or \VR) had a significant effect on the perception of haptic textures and the exploration behaviour of the participants.
-The textures were on average perceived as \enquote{rougher} and with a higher sensitivity when touched with the real hand alone than with a virtual hand either in \AR, with \VR in between.
+The textures were on average perceived as \enquote{rougher} when touched with the real hand alone than with a virtual hand either in \AR, with \VR in between.
+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.

 In the next chapter we present a second user study where we investigate the perception of simultaneous and co-localised visual and haptic texture augmentation.
 We will use the same system presented in \chapref{vhar_system} and a visual rendering condition similar to the \level{Real} condition of this study, in \AR without the virtual hand overlay.
