\section{Conclusions}

In this section we'll give our conclusions of the project, although
we weren't enable to let persons experiment with our application, we
can drawn some conclusions of the project.

\subsection{Head Tracking}
With the OpenGL library is't not difficult to make a good perspective
world. It can be done by mainly one function. The difficulty for the
head tracking was to cooperate good with the Nintendo Wii controller
and his sensor bar, which is being discussed in the problem section.
A disadvantage of using Wii controller is, the small angle of the
camera. To have a good moving space in which the camera can track the
dots, you must be on a long distance of the camera, and so the
screen. And for that you must have a big screen to have a nice view.
If you are to close to the camera, you easily move out of the range
and your head cannot be tracked anymore.

\subsection{Stereo Vision}
