How do I know where I am? Location Dependent service(s) • Outdoors: GPS or from the network operators knowledge [resolution: 100m to sub-centimeter] • Indoor: IR and RF beacons, triangulation, knowing what you can see or hear What can I do with this knowledge? KTH students built a JAVA Applet which gets data from GPS unit and dynamically displays a list of the information available - as a function of where you are: ♦ if near bus, subway, train stop - you get transit information - potentially with real-time schedule - since the system knows current location of vehicles ♦ list of restaurants, shops, etc. where you are and in the direction you are headed ◆ the scope is based on your velocity vector - so if you move quickly it reduces detail, but increases the scope ♦ map information with updated position How do I know who I’m with or what I’m near? • Olivetti, Xerox, and MIT - using IR emitters as “ID” tags ♦ Olivetti put them on people, equipment, … ♦ Xerox put them on electronic notepads, rooms, … ♦ MIT Media Lab is putting them on people + lots of inanimate objects (clock, fish tank, …) Maguire Location Dependent service(s) 13: 67 of 91 maguire@kth.se 2010.03.21 Internetworking/Internetteknik
