2. 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.

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

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.
Manninder

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

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

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

ArcGIS Floor Plans

12. 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 ?
