\section{Thesis outline}
|
||
|
|
|
||
|
|
First, in Chapter~\ref{sote}, we present a review of the state of the art on the fields that are interesting for us.
|
||
|
|
This chapter start by video streaming.
|
||
|
|
Then it reviews the different manner of performing 3D streaming.
|
||
|
|
The last section of this chapter focuses on 3D interaction.
|
||
|
|
|
||
|
|
Then, in Chapter~\ref{bi}, we analyse the impact of the UI on navigation and streaming in a 3D scene.
|
||
|
|
We first present a user study that we conducted on 50 people that shows that adding 3D objects behaving as navigation aid can have great impact on how easy it is for a user to perform tasks such as finding objects.
|
||
|
|
We then setup a basic 3D streaming system that allows us to replay the traces collected during the user study and simulate 3D streaming at the same time.
|
||
|
|
Finally, we analyse how the presence of navigation aid objects impacts the streaming, and we propose and evaluate a few techniques that rely on these objects and that can increase the quality of experience.
|
||
|
|
|
||
|
|
In Chapter~\ref{d3}, we develop the most important contribution of this thesis: DASH-3D.
|
||
|
|
DASH-3D is an adaptation of the DASH standard for video streaming.
|
||
|
|
We first describe how we adapt the concepts of DASH to 3D content.
|
||
|
|
We then present a client that can benefit for the DASH format.
|
||
|
|
We finally evaluate the different parameters of our client.
|
||
|
|
|
||
|
|
In Chapter~\ref{d3i}, we explain the whole implementation of DASH-3D.
|
||
|
|
Implementating DASH-3D required a lot of effort, and since both user studies and simulations are required, we describe the two clients we implemented: one client using web technologies to enable easy user studies and one client native that allows us to run efficient simulations and precisely compare the impact of the parameters of our system.
|
||
|
|
|
||
|
|
In Chapter~\ref{sb}, we integrate back the interaction ideas that we developed in Chapter~\ref{bi} into DASH-3D.
|
||
|
|
We first propose a new style of navigation aid, and we then explain how simply reusing the ideas from Chapter~\ref{bi} is not sufficient.
|
||
|
|
We then explain a more efficient way of applying those ideas.
|
||
|
|
Finally, we present a user study that provides us with traces on which we can perform simulations.
|
||
|
|
We evaluate the impact of our extension of DASH-3D on the quality of service and on the quality of experience.
