\section{Augmented Reality} \label{augmented_reality} % Intro with Sutherland % A few examples of usages now \subsection{Principles, Capabilities and Limitations} \label{ar_intro} Based on the interaction loop presented in \figref[introduction]{interaction-loop}, we briefly detail the fundamental main components that compose any AR application: tracking, rendering and display. \subsection{What is Augmented Reality?} % Definition of \cite{azuma1997survey} % Recall Milgram and differences with VR \subsection{How does AR work?} % How it works briefly \subsubsection{Calibrating \& Tracking} % \cite{marchand2016pose} \subsubsection{Modeling \& Rendering} \subsubsection{Display} % Bimber and types of AR % State of current HMD \subsection{How Virtual is Perceived in AR} \label{ar_perception} \subsection{Interacting with Virtual and Augmented Content} \label{ar_interaction} \subsubsection{Virtual Hand Rendering in AR} \label{ar_interaction_hands} \subsection{Conclusion} \label{ar_conclusion}
