\section{Project Objectives}\label{aim}
Recognising the benefits of a shared control approach in a BCI-controlled intelligent wheelchair, the aim of the project is to incorporate the same into the virtual reality EPW developed in the Neurophysiology Lab by previous work (Grychtol, 2010). The following have been identified as the main tasks of the project:
\begin{itemize}
\item Review of shared control approaches in the field of assistive robotic wheelchairs
\item Understanding the virtual simulator environment and control of the virtual EPW
\item Equipping the wheelchair with appropriate sensors in an optimal arrangement
\item Developing shared control algorithms for providing obstacle avoidance, collision avoidance and wall following assistance
\item Evaluating the shared control strategy using an appropriate assessment procedure
\end{itemize}
