Presentation Transcript

  1. Dr. GunhoSohn (Supervisor) Alec Mantha Maninder Gill Patrick Eagan Phillip Robbins Campnav

  2. 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.

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

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

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

  6. 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

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

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

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

  10. 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 ?

  11. 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 POI’s.
