\section{Introduction}

For the master course Interactive Virtual Environments (2IV55), group 7 chose to create an experiment using the Nintendo Wii remote. This short proposal will give
an overview of the project and its organization.

% \subsection{Group members}

% Group 7 consists of four CSE students:

% \begin{itemize}
%   \item Dennis Peeten (0571361)
%   \item Maik Teurlings (0591600)
%   \item Oliver Schinagl (0580852)
%   \item Wilrik De Loose (0601583)
% \end{itemize}

\subsection{Problem}

The sense of depth when using an input device with 3D mouse functionality like the Wii remote, feels sometimes awkward and unnatural. To overcome this handicap,
group 7 defined an experiment. The results should give an insight in the usability of such an 3D input device.

\subsection{Approach}

The users participating in the experiment will do a number of simple tests. The goal is to put a set of 10 basic shapes as quickly as possible in the corresponding
holes. A Wii remote is used to locate a block above a hole and then put it into the box. \\

For this experiment, a second Wii remote is going to keep track of the user's eyes. This makes it possible to track the head movement and thus create the illusion
of a virtual 3D environment. \\

A number of factors will play a role in the experiment:

\begin{itemize}
  \item Head tracking (with/without)
  \item Stereo glasses red/blue (with/without)
  \item Depth of the field
  \item Shadow projection
\end{itemize}

\subsection{Evaluation}

Each user will do the test a number of times. Each test can vary in the given factors. When all of the data is gathered, one may be able to see a relation between
3D navigation with and without head tracking, stereo vision and with different application settings.
