\section{Performance Overview} % all paths we evaluated \begin{figure} \input{gfx/paths} \caption{The four paths that were part of the evaluation. Starting positions are marked with black circles. For a better visualisation they were slightly shifted to avoid overlapping.} %\commentByFrank{font war korrekt, aber die groesse war zu gross im vgl. zu den anderen} \label{fig:paths} \end{figure} % To give a brief overview of the system's performance we look back at the evaluation provided in \cite{ebner-16}. Here, 4 distinct walks were conducted within the faculty building (cf. fig. \ref{fig:paths}). No smoothing was carried out. We used \SI{7500}{particles} as realisation and calculated the weighted arithmetic mean of the particles as state estimation. The ground truth was measured by recording a timestamp at marked spots on the walking route, similar as described in the competition guidelines. Starting uniformly distributed, the median error for all conducted walks are listed in table \ref{tbl:errNexus} for the Motorola Nexus 6 and the Samsung Galaxy S5. Additionally performing a smoothing step, would further improve the results and reduces temporal errors, as shown in \cite{fetzer-16}. % \begin{table}[h] \caption{Median error for all conducted walks without smoothing. } \label{tbl:errNexus} \centering \begin{tabular}{|l|c|c|c|c|} \hline \textbf{Device:} & Path1 & Path2 & Path3 & Path4 \\\hline Motorola Nexus 6 & \SI{2.62}{\meter} & \SI{2.14}{\meter} & \SI{2.46}{\meter} & \SI{2.75}{\meter} \\\hline Samsung Galaxy S5 & \SI{ 6.35}{\meter} & \SI{4.21}{\meter} & \SI{5.03}{\meter} & \SI{6.79}{\meter} \\\hline \end{tabular} \end{table}
