Introduction • Indoor Localization System is needed – Poximity based advertisement – User behavior analysis • Challenge: deployment cost – Fingerprints map – Hardware • Solution: Helvar BLE devices 3
System design New BLE signal strength readings: [BLE MAC 1, signal 1; Distance calculation User position estimation BLE MAC 2, signal 2; …] BLE 3(x 3, y 3) BLE 1(x 1, y 1) 4 BLE 2(x 2, y 2)
UI design • Using simple non-sophisticated controls • Modern Android elements design • Focus on functionality 5
UI design Bluetooth dialog Main screen 6 Coordinates dialog box
UI design • Map as canvas • Simple representation of objects on the map: – Luminair (blue) – Phone location (red) • Updated whenever new data is pushed 7
Challenges • Reliable measurements • Extensive testing • Formula design 8
Practices • Meeting • Sharing information • Communication • Tracking the project status 9
