\section{Classification}
\subsection{Comparison of methods of recording}
The different methods of recording (EEG, EMG and Low frequencies) also differ in the results. An ANOVA gives a $p$-Value of $2.09\cdot 10^{-8}$ ($F=108.29$) for all classifications done on 4 different movements and rest.

\subsection{EMG}
In figure~\ref{fig:overviewEMG} the different settings for classification based on EMG-data are shown. Default has values as in \ref{mat:default}. The runs with pause leave out the data 1 second before the movement begins (cf. \ref{mat:pause}).

When calculating an ANOVA on the data with and without pause we get a $p$-Value of $3.9\cdot 10^{-9}$ ($F=41.68$).
\subsection{EEG}
In figure~\ref{fig:overviewEEG} the different settings for classification based on EEG-data are shown. Default has values as in \ref{mat:default}. The runs with pause leave out the data 1 second before the movement begins (cf. \ref{mat:pause}). Runs with offset have an offset of 1 or 2 (cf. \ref{mat:offset}).

\subsection{Low Frequencies}
In figure~\ref{fig:overviewLF} the different settings for classification based on LowFrequency(LF)-data are shown. Default has values as in \ref{mat:default}. The runs with pause leave out the data 1 second before the movement begins (cf. \ref{mat:pause}). Runs with offset have an offset of 1 or 2 (cf. \ref{mat:offset}).
