% Even before manipulating a visual representation to induce a haptic sensation, shifts and latencies between user input and co-localised visuo-haptic feedback can be experienced differently in AR and VR, which we aim to investigate in this work.
%Imagine you're an archaeologist or in a museum, and you want to examine an ancient object.

\item A system for rendering virtual vibrotactile roughness textures in real time on a tangible surface touched directly with the finger, integrated with an immersive visual AR/VR headset to provide a coherent multimodal visuo-haptic augmentation of the real environment.
\item A psychophysical study with 20 participants to evaluate the perception of these virtual roughness textures in three visual rendering conditions: without visual augmentation, with a realistic virtual hand rendering in AR, and with the same virtual hand in VR.

%First, we present a system for rendering virtual vibrotactile textures in real time without constraints on hand movements and integrated with an immersive visual AR/VR headset to provide a coherent multimodal visuo-haptic augmentation of the real environment.
%
%An experimental setup is then presented to compare haptic roughness augmentation with an optical AR headset (Microsoft HoloLens~2) that can be transformed into a VR headset using a cardboard mask.
%
%We then conduct a psychophysical study with 20 participants, where various virtual haptic textures on a tangible surface directly touched with the finger are compared in a two-alternative forced choice (2AFC) task in three visual rendering conditions: (1) without visual augmentation, (2) with a realistic virtual hand rendering in AR, and (3) with the same virtual hand in VR.
