Dr. Gunho Sohn (Supervisor) Alec Mantha Maninder Gill Patrick Eagan Phillip Robbins CAMPNAV Indoor Navigation at York. U
Why Indoor Navigation ? � Shortest paths � Track for path hazards � Evacuation routes � Information on building access (elevator stairs etc. ) � Finding rooms
Objective � Make buildings more accessible for disabled people. � Building tours � Emergency Fire routes
Stakeholders � Esri � Mircom � York. U (Counselling & Disability Service)
Technical Design � Android Application based � Required known location of Wi. Fi routers on campus � Fingerprint Mapping in order to determine locations � Accuracy of about (2 -3)m
Implementation � Fingerprint mapping � GIS database integration � Real time signal data collection � Querying database for fingerprint solution
Similar Companies � Point Inside (Shopping) � Meridian (Museums and Casinos) � Trapeze Networks (Wi. Fi router manufacteruer) � Ekahau (Security RFID tags and workflows) � WIFARER (SDK to create indoor navigation)
Similar Companies Cont. � T-PN (Uses IMU’s in conjunction with GPS) � Wifi. Slam (Apple just purchased for $20 M)
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)
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)
Patents cont. � Ultrasonic positioning system with high accuracy (Trilateration using sound) � WIFI based indoor positioning system (Trilateration)
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)
