Dr. Gunho Sohn (Supervisor) Alec Mantha Maninder Gill Patrick Eagan Phillip Robbins CAMPNAV 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 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

APs 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 Data structure

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 ?

Acknowledgements We would like to thank our mentors, supervisors and stakeholders. We would like to thank the York University Planning Department for giving us the floor plans.

We would like to thank the Counselling & Disability Service for giving us a list of POIs.
