Motivation Indoor Navigation System Campus Touring Evacuation Routes GPS unable to reach indoors Wi-Fi is a good alternative Campus Touring Evacuation Routes

Background Wi-Fi signal strength 𝐿 𝑝 =10 log⁡( 𝑃 1𝑚𝑊 ) Measured from multiple access points 𝐿 𝑝 =10 log⁡( 𝑃 1𝑚𝑊 )

Methodology GIS Database Location Analysis AutoCad file manipulation Wi-Fi fingerprint map creation Location Analysis Deterministic approach for rough position Probabilistic approach for clarity Le Dortz, et al.

Methodology Android Application Point to point direction Alternate route sourcing Map display Scalable Map Meridian App

Progress Map Information Obtained Application AutoCad Files Wi-Fi access point location Application Mobile language chosen Basic structure of application developed

Discussion from last Presentation Fingerprint? Unique signal strength from multiple AP for each position in Vari Hall Create map of signals Compare user signal to map of signals Chan et al.

Discussion for this week Grid Density? How close is too close? King et al.

Conclusion Steps Completed: We now have the floor plans as well as the list of routers in Vari Hall We have a list of the POI’s Next Steps: We need to create a WiFi logging application We need to start coding

Time Management Coding Survey Software WiFi Survey Data Processing GIS Mapping Coding App Final Presentation/ Report 3 weeks 4 weeks 2 weeks 6 weeks

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.
