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.
