Presentation Transcript

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

  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 macadress)

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

  14. THE END
