+This chapter presents an overview of previous work on perception and interaction in the context of wearable haptics and augmented reality.
+%
+It first gives an overview of the sense of touch, and how wearable haptic devices and renderings have been used to provide haptic feedback to enhance the touch perception and interaction with virtual and augmented objects, with a focus on vibrotactile feedback and haptic textures.
+%
+Secondly, it introduces the principles and user perception of augmented reality, and describes the 3D interaction techniques used in \AR and \VR environments to interact with virtual and augmented objects, in particular using the visual rendering of the user's hand.
+%
+Finally, it presents how multimodal visual and haptic feedback have been combined to modify
