 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 realization and calculated the weighted arithmetic mean of the particles as state estimation. 
+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}.
