Recall…. Indoor Navigation System
GPS unable to reach indoorsWi-Fi is a good alternative
GIS DatabaseAutoCad file manipulationWi-Fi fingerprint map creation
Location AnalysisDeterministic approach for rough positionProbabilistic 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 sizeReduces 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 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
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.
