The answer is always the same, it depends. The answer is always the same, it depends.
As for this museum scenario, the results for detecting the standing activity are not satisfying and a more advanced approach should be considered.} As for this museum scenario, the results for detecting the standing activity are not satisfying and a more advanced approach should be considered.}
\add{In contrast, the detection rates for walking up or down are certainly better.
\add{The detection rates of up and down sind nicht ganz so schlecht, as the main reason ... With only a single exception in walk 3 (cf. chapter \ref{sec:exp:loc}), the approach makes it possible to direct particles smoothly over stairs.
all these changes could be detect with} Due to the lag, however, there is a noticeable delay of the estimation when entering the staircase.
During this short period of time, the particles gather in front of the staircase, as they only receive a corresponding weighting when the activity changes.
In buildings with many successive stairs, this could lead to further problems, as it affects the PDR-based movement of the particles.
Finally, it is not possible to derive the smartphone or the user from the recognition rates, which recommends a general use of the approach. Nevertheless, in a scenario such as the present, the absolute positioning of Wi-Fi should compensate for this.
As a final notice on this approch, it is not possible to derive the smartphone or the user from the detection rates, which recommends a general use of the approach.}
%das brauchen wir glaub nimmer. das oben ist schon nicht verkehrt.
%\add{The main reason to utilize such a method was to detect floor changes.
%Regardless of the detection rate above, the method is able to detect all floor changes of the conducted walks.
