 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.}

+\add{In contrast, the detection rates for walking up or down are certainly better. 
+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.
+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. 
+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.}
