In Chapter~\ref{bi}, we described how it is possible to modify a user interface to ease user navigation in a 3D scene, and how the system can benefit from it.
In Chapter~\ref{d3}, we presented a streaming system that takes neither the interface nor the user interaction into account.
In Section~\ref{sb:bookmarks}, we describe how we embed the bookmarks into our DASH framework, and how we precompute data in order to improve the user quality of experience.
In Section~\ref{sb:evaluation}, we describe the user study we conducted, the data we collected and we analyse the results.
