\subsubsection{Models}
In this user study, we display two successive 3D models to the users:
\textbf{A FIGURE WOULD BE NICE !!!}
\begin{itemize}
\item For the tutorial phase, we use a model derived from a video game, representing a small scene, in order to prevent users from getting lost in the scene.
\item For all the other parts of the experiment, we use a larger version of the Singaporean district 3D model, that include neighbouring districts such as Central Business District.
\end{itemize}

\subsubsection{Experiment}
The experiment is articulated into four phases: a tutorial, a comparison between interfaces with and without bookmarks, a comparison between two streaming policies, and a final navigation during which the user is looking for objects in the scene.

This may be due to the lower number of users clicking on bookmarks.
However, Figure~\ref{sb:psnr-third-experiment-after-click} is clear: the optimized policy performs way better after a click on a bookmark.
