In this chapter, we designed and implemented a system for rendering virtual visuo-haptic textures that augment a real surface.
Directly touched with the fingertip, the perceived roughness of the surface can be increased using a wearable vibrotactile voice-coil device mounted on the middle phalanx of the finger.
We adapted the 1D sinusoidal grating rendering method, common in the literature but not yet integrated in a direct touch context, for use with vision-based tracking of the finger and paired it with an immersive \AR headset.

Our wearable visuo-haptic augmentation system enable any real surface to be augmented with a minimal setup.
It also allows a free exploration of the textures, as if they were real (\secref[related_work]{ar_presence}), by letting the user view them from different poses and touch them with the bare finger without constraints on hand movements.
