Recall….  Indoor Navigation System GPS unable to reach indoors Wi-Fi is a good alternative  GIS Database AutoCad file manipulation Wi-Fi fingerprint map creation  Location Analysis Deterministic approach for rough position Probabilistic approach for clarity Le Dortz, et al.

Progress Since Last Presentation  Completed the Signal Surveying software.  WiFi only

Progress Cont.  Completed the location algorithm in java and currently integrating it into the mapping application.  AR toolkit is used to render virtual reality with the live camera feed.

Progress Cont.  Implemented Google Maps in the Android Device.  Overlaid rough Vari Floor Plans in Google Maps.

Selected a Data Structure  Selection of sparse matrix data structure. Drastically cuts data base size Reduces search time  Completed porting Algorithm from Matlab to Java

Performing Statistical Tests  A 2 nd order trend surface “best-fit polynomial” added to data.  The highest signal intensities are near the router.

Finger Print  Information retained from a Wi-Fi scan.  Does not need to connect to any AP’s

Final Steps  Georeference and ArcGIS conversion of floor plans. We need to do this for the lassonde lecture hall A.  Adaptation of KML mapping data with location service. ArcGIS Floor Plans

 Selection of data structure? - Real Time Computations - Pre Sorting Data?  Weights of data? - Should weights degrade with lower decibel signals ? - Reliability and accuracy of different data sets ? Data structure
