Bas Kerkhoven talks about Indoor positioning at Schiphol

Transcript

2. Indoor positioning My journey with indoor positioning Bas Kerkhoven
3. Schiphol Indoor Way Finding • Up to date map • User’s location • Routing • Search facilities
5. How did we achieve this? • Map solution connected to GIS (geographic information system) • Routing network • Search GIS
6. Indoor positioning challenges • Lot’s of concrete/metal • No/bad GPS • Solution that is cross platform
7. Positioning solutions Magnetic fields And a lot more
8. Common factors • Fingerprint the location • Third party SDK • System restrictions • Combined with phone sensors
9. What we couldn’t use: Magnetic fields • It’s always there • Can be tracked with phone sensors • Not usable for us
10. So which one did we use?
11. First solution • Started with 
 • Infrastructure already installed
 • Almost everyone has WiFi on
12. WiFi • Triangulation • iOS restrictions, system information • No signal strength
 
 Benefit:
 Almost everyone has
 their WiFi on
13. WiFi cons • Load distributors
 • Lack of signal strength
 • Have to be connected to SSID
14. What was next? • Next is: 
 • 2000 beacons installed across Schiphol
 • Multiple weeks of fingerprinting and testing
15. Bluetooth • Triangulation • System gives more information
 Disadvantage:
 A lot of people have
 their Bluetooth off
16. Bluetooth pros • Accuracy +/- 5 meters
 • Reusability for vendors/airlines
17. Bluetooth cons • Location snapped on line
 • Battery drain
18. Live! • Working solution
 • Correct positioning • Routing along location
19. But there is more! • Apple announced indoor positioning
 WWDC 2014 - Session 708 - iOS
20. What does Apple need? • Blueprints OR • GIS
 (geographic information system)
21. Fingerprinting • Surveyors send to location • Blueprint/GIS used to determine location • Physically walking around Survey App
22. What does Apple record? • Captures all RF-signals (mostly WiFi) • No bluetooth • Sensors of the phone • No system restrictions
23. Evaluation • Asses the fingerprint • Redo areas where needed • Distribute data
24. How do we retrieve the location?
25. Build into CoreLocation • No special API’s • No extra SDK • No authentication required
26. So it’s live for everyone?
27. How do I get the location?
28. Determine it’s an indoor location
29. Difference indoor/outdoor • CLFloor != nil -> Indoor location • Best possible location fix
30. Pros • Automatically gives best location • Low battery consumption • Smooth updates
31. Cons • Only iOS • Exclusive to large veneus (for now) • Apple has to provide fingerprinting
32. This was my journey :)
