 %
 One hypothesis is that this dimension could be the perceived stiffness of the textures, with Metal Mesh and smooth textures appearing stiffer than the other textures, whose granularity could have been perceived as bumps on the surface that could deform under finger pressure.

 The \level{Mixed} rendering was always in between, with no significant difference from the other two.
 This suggests that touching a virtual vibrotactile texture on a tangible surface with a virtual hand in \VR is different from touching it with one's own hand: users were more cautious or less confident in their exploration in \VR.
 This does not seem to be due to the realism of the virtual hand or the environment, nor to the control of the virtual hand, all of which were rated high to very high by the participants (\secref{results_questions}) in both the \level{Mixed} and \level{Virtual} renderings.
-Very interestingly, the evaluation of the vibrotactile device and the textures was also the same between the visual rendering, with a very high sense of control, a good realism and a very low perceived latency of the textures (\secref{results_questions}).
+The evaluation of the vibrotactile device and the textures was also the same between the visual rendering, with a high sense of control, a good realism and a low perceived latency of the textures (\secref{results_questions}).
 Conversely, the perceived latency of the virtual hand (\response{Hand Latency} question) seemed to be related to the perceived roughness of the textures (with the \PSEs).
 The \level{Mixed} rendering had the lowest \PSE and highest perceived latency, the \level{Virtual} rendering had a higher \PSE and lower perceived latency, and the \level{Real} rendering had the highest \PSE and no virtual hand latency (as it was not displayed).
