Situational Web

  1. 1. 1 Situational Web UK Museums on the Web 2009 Web connectivity and location based services Paul Golding Copyright Paul Golding, 2009 Saturday, 5 December 2009
  2. 2. 2 Cells have IDs = location You’re in cell 111, 113, 115 Can be aggregated 115 Might be free! 111 x,y, radius, 112 113 postcode, landmarks.... 114 Web App API Location Location Cellular networks inherently Gateway enabled track location using cell ID app Cell IDs are broadcast = public can access them Copyright Paul Golding, 2008 Saturday, 5 December 2009
  3. 3. 3 Location inaccuracies “Nearest” according to network Where’s nearest? Must also have good self-location UI Actual nearest E-OTD TDOA AOA Extent of problem related to cell size, location technology and geo-coding/application intelligence Copyright Paul Golding, 2008 Saturday, 5 December 2009
  4. 4. Network location works well in urban areas 4 UK Networks: Dense urban: 300m Semi-urban: 600m - 1200m Rural: 1km - 10km Copyright Paul Golding, 2008 Saturday, 5 December 2009
  5. 5. Devices and device apps 5 iPhone 3G: GPS, Cell, WiFi Google Maps: GPS, Cell Smartphone/GPS penetration: est. 80% 2015 Loki: WiFi, Cell (Skyhook Wireless Inc.) Copyright Paul Golding, 2008 Saturday, 5 December 2009
  6. 6. 6 Location programming interfaces Network API Report (GPS) Application Request (MSISDN) Model HTTP Request (Cell, MSISDN) View API Location Managers: Controller Yahoo Fire Eagle, Google Latitude App Server Location e.g. Location API Framework HTML5 WiFi Cell GPS GIS Geo-coded (e.g. Google Maps) Content Copyright Paul Golding, 2008 Saturday, 5 December 2009
  7. 7. 7 Trigger-based Location Location events are asynchronous (i.e. to user query) Polling - including AJAX - inefficient (battery life) Network based triggering, but still needs location (e.g. GPS x,y) Various architectural possibilities, but not supported on UK networks Copyright Paul Golding, 2008 Saturday, 5 December 2009
  8. 8. 8 Proximity Services Short-range sensor-based services: Possibilities for use indoors: RFID and various contactless systems (e.g. NFC, Tikitag) Barcode scanners (Ecrio MoBeam) QR-codes (photo scanning) Bluetooth/WiFi/Zig-Bee (e.g. Ekahau) Visual recognition (augmented reality) Copyright Paul Golding, 2008 Saturday, 5 December 2009
