The three visual rendering conditions and the experimental procedure of the two-alternative forced choice (2AFC) psychophysical study.
%
During a trial, two tactile textures were rendered on the augmented area of the paper sheet (black rectangle) for 3\,s each, one after the other, then the participant chose which one was the roughest.
%
The visual rendering stayed the same during the trial.
%
(\level{Real}) The real environment and real hand view without any visual augmentation.
%
(\level{Mixed}) The real environment and hand view with the virtual hand.
%
(\level{Virtual}) Virtual environment with the virtual hand.

%The pictures are captured directly from the Microsoft HoloLens 2 headset.

Our visuo-haptic rendering system, described in \secref{method}, allows free exploration of virtual vibrotactile textures on tangible surfaces directly touched with the bare finger to simulate roughness augmentation, while the visual rendering of the hand and environment can be controlled to be in AR or VR.
