1. Indoor Navigation at YorkU Dr. Gunho Sohn (Supervisor) Alec Mantha Maninder Gill Patrick Eagan Phillip Robbins

2. Why Indoor Navigation ?  Shortest paths  Track for path hazards  Evacuation routes  Information on building access (elevator stairs etc.)  Finding rooms

3. Objective  Make buildings more accessible for disabled people.  Building tours  Emergency Fire routes

4. Stakeholders  Esri  Mircom  YorkU (Counselling & Disability Service)

5. Technical Design  Android Application based  Required known location of WiFi routers on campus  Fingerprint Mapping in order to determine locations  Accuracy of about (2-3)m

6. Implementation  Fingerprint mapping  GIS database integration  Real time signal data collection  Querying database for fingerprint solution

7. Similar Companies  Point Inside (Shopping)  Meridian (Museums and Casinos)  Trapeze Networks (WiFi router manufacteruer)  Ekahau (Security RFID tags and workflows)  WIFARER (SDK to create indoor navigation)

8. Similar Companies Cont.  T-PN (Uses IMU’s in conjunction with GPS)  WifiSlam (Apple just purchased for $20M)

9. Patents  Indoor navigation using stored geographical bearing information (giving a geographic bearing between finger print points)  User generated pedestrian and indoor shortcut routes for navigation systems (taking pictures of shortcuts)

10. Patents cont.  Squaring loss inhibition for low signal levels in positioning systems (Signal Attenuation)  Indoor localization using commercial frequency-modulated signals. (Sending a signal over wifi for Trilateration)

11. Patents cont.  Ultrasonic positioning system with high accuracy (Trilateration using sound)  WIFI based indoor positioning system (Trilateration)

12. Patents cont.  Ranging and distance based wi-fi spectrum selection (Trilateration using transmitted signal time of flight)  Method and device for fingerprinting of network devices (Identifying routers off of mac adress)

13. Engineering Courses  Math 2565 (Stats)  Eng 3300 (GIS)  Eng 3150 (Photogrammetry)  Eng 3120 & 3130 (Least Squares)  Eng 4110 (GPS)
