\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 its 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}

The applied red-blue stereo vision is one of the least realistic alternatives of stereo vision. Yet, it is the easiest to implement and still very effective. The created images provide the user the illusion of depth in a very usable way. The distance between objects can easily been seen from a still image. This is also a big disadvantage of head tracking; without moving, the image provides no additional "depth info".
