\subsectionstarbookmark{The Senses of Vision and Touch}

Touch is the only sense that allows not only to perceive the environment, but also to interact with it. Explain how both vision and touch are complementary and important for combined perception and interaction with the environment.

\subsectionstarbookmark{Wearable Haptics and the Augmentation of Touch}

Present what is wearable haptics, how they can be used to augment the sense of touch~\autocite{pacchierotti2017wearable}. Detail then how they have been used with virtual reality, but how little they have been used with augmented reality.

\subsectionstarbookmark{Augmented Reality is Mostly Visual}

Explain what is augmented reality, and why it is important to use wearable haptics with it.

\sectionstarbookmark{Augmenting the Sense Realities: Challenges of using Wearable Haptics in Augmented Reality}

Explain what are the challenges of using wearable haptics with augmented reality, and how this thesis addresses them.

\sectionstarbookmark{Thesis Objectives}

Objective of the thesis: To understand how visual and wearable vibrotactile haptic feedback compare or complement each other in user perception and experience of touch in augmented reality. Integrate visuo-haptic augmentations to improve the user perception and interaction with the augmented environment.

Two main axes of research: (I) augmenting the visuo-haptic texture perception of tangible surfaces, and (II) improving virtual object manipulation with visuo-haptic augmentations of the hand.

Touch allows to perceive the environment and interact with it, thus it motivates these two axes of research.

% it's a mix of augmented reality, virtual reality, vibrotactile feedback for visuo-tactile augmentation of the real world. Such multimodal rendering raise many questions on how to design, how renderings interact and complete each other, to give one perception
