+
+Wearable haptic devices provide tactile sensations to the skin in a portable and unobtrusive way. %, to render haptic feedback of virtual objects.
+%
+Their use has been little explored in augmented reality (AR), where virtual content is integrated into real world perception.
+%
+%They have been used to render rich and various haptic feedback to virtual object in virtual reality (VR) or to augment the perception of a real object being touched.
+%
+In this thesis, we investigate the integration of wearable haptic devices with AR in the context of direct hand interaction with virtual and augmented objects.
+%
+We consider two axes of research: (I) providing plausible and coherent visuo-haptic texture augmentations, and (II) improving virtual object interaction with visuo-haptic augmentation of the hand.
+
+First, we study how visual rendering affects the perception of virtual vibrotactile textures that augment real surfaces directly touched by the finger.
+%
+To this end, we propose (1) a system for rendering visuo-haptic virtual texture augmentations using an AR headset and a wearable vibrotactile device. We then (2) evaluate how the roughness perception of virtual haptic textures differs in AR \vs virtual reality (VR) and when touched by a virtual hand \vs one's own hand. Finally, we (3) investigate the realism, plausibility and coherence of combining visual and haptic texture augmentations in AR.
+
+Secondly, we investigate how the visuo-haptic rendering of the hand improves its direct manipulation of virtual objects in AR in terms of performance and user experience.
+% address the challenge of manipulating virtual objects directly with the hand in AR, which is a key interaction but is still challenging due to visual and haptic limitations.
+%
+We first (1) explore the effect of six visual renderings of the hand that provide contact feedback with the virtual object.
+%
+We then (2) evaluate two vibrotactile contact techniques, provided at four different locations on the real hand, and compared to the two most representative visual hand renderings from the previous contribution.
