Framework Introduction System design UI design Challenges Practices Live demo

Introduction Indoor Localization System is needed Poximity based advertisement User behavior analysis Challenge: deployment cost Fingerprints map Hardware Solution: Helvar BLE devices

System design BLE3(x3, y3) BLE2(x2, y2) BLE1(x1, y1) New BLE signal strength readings: [BLE MAC 1, signal1; BLE MAC 2, signal 2; …] Distance calculation User position estimation System design BLE2(x2, y2) BLE1(x1, y1) BLE3(x3, y3)

UI design Using simple non-sophisticated controls Modern Android elements design Focus on functionality

UI design Bluetooth dialog Main screen 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

Challenges Reliable measurements Extensive testing Formula design

Practices Meeting Sharing information Communication Tracking the project status
