Recall…. Indoor Navigation System GIS Database Location Analysis 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 Patrick

Progress Cont. Completed the Algorithm in Matlab, nearly done integrating it into the mapping application. Currently looking into the Augmented Reality toolkit for Android. Manninder

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 Nearly completed porting Algorithm from Matlab to Java

Manninder

Performing Statistical Tests A 2nd 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 Alec

Future Steps Georeference and ArcGIS conversion of floor plans. Adaptation of KML mapping data with location service. Integration in android app. Alec ArcGIS Floor Plans

Discussion for this week 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 ? Phillip
