We designed and implemented a system for rendering virtual haptic grating textures on a real tangible surface touched directly with the fingertip, using a wearable vibrotactile voice-coil device mounted on the middle phalanx of the finger. %, and allowing free explorative movements of the hand on the surface.
%
This tactile feedback was integrated with an immersive visual virtual environment, using an OST-AR headset, to provide users with a coherent multimodal visuo-haptic augmentation of the real environment, that can be switched between an AR and a VR view.

We investigated then with a psychophysical user study the effect of visual rendering of the hand and its environment on the roughness perception of the designed tactile texture augmentations: without visual augmentation (\level{Real} rendering), in AR with a realistic virtual hand superimposed on the real hand (\level{Mixed} rendering), and in VR with the same virtual hand as an avatar (\level{Virtual} rendering).

%Only the amplitude $A$ varied between the reference and comparison textures to create the different levels of roughness.
