The system is able to handle problems like sample impoverishment and multimodal densities, occurring through the use of a particle filtering scheme. -The main advantage of our approach is its suitability for practical use. +\add{Based on the good results in this challenging scenario, we believe that our solution can be adapted to many other public buildings and environments, resulting in a very generally usable solution for self-localization of pedestrians using smartphones. +Previous versions of the system have already proven themselves in other, more modern buildings, which supports this claim to general use.} + +%novel stuff +\add{Thanks to the novel contributions presented, we have been able to further increase the robustness and accuracy of the system. +To a large extent, this was achieved by using the navigation mesh. +It allows to map continuous movements and enables to reduce the map sizes to only a few megabytes for a complete building. +The problem of sample impoverishment can be addressed easily by incorporating the here presented method onto the state transition of the particle filter. +In combination with the threshold-based activity recognition, both methods further enhance the robustness.} +Given the improvements above and those achieved in previous works, the main advantage of our approach is its suitability for practical use. Compared to other state-of-the-art solutions, the setup time is only a few hours and does not require any expert knowledge or hardware. +\add{The system should require as little manual effort as possible. +This is mainly achieved by the optimization scheme, providing all necessary parameters for the Wi-Fi model.} The localization runs solely an a commercial smartphone, thus no connection to a server or the Wi-Fi infrastructure is required. -By using navigation meshes we are able to reduce the map sizes to only a few megabytes for a complete building. + Nevertheless, there is still room for further improvements and future work. Through the change from a graph to a mesh, we lost the ability to easily find the shortest path for navigation purposes as described in \cite{Ebner-16}. diff --git a/tex_review/chapters/experiments.tex b/tex_review/chapters/experiments.tex index b496adb..c19b9d4 100644 --- a/tex_review/chapters/experiments.tex +++ b/tex_review/chapters/experiments.tex @@ -478,8 +478,4 @@ It does not provide a smooth estimated path, since it depends more on an accurat At the end, in the here shown examples we only searched for a global maxima, even though the KDE approach opens a wide range of other possibilities for finding a best estimate. \add{A detailed examination of the runtime performance of the used estimation methods in comparison to the state-of-the-art can be found in \cite{Bullmann-18}.} -\commentByToni{Diskussion, wie die Contributions uns jetzt geholfen haben.
