Tracking individuals Big brother (but he is a nice guy): –Where am I? –Where is my meeting partner? –Where did I leave my keys ?- well, no problem...
Tracking groups –Which of the cantinas have people I prefer having lunch with gone to? –Are there any interesting people in the faculty room that I would like to talk to? –How long time have they been there?
Tracking behaviour patterns –Where do people gather? –Who stops and talk together spontaneously? –Are there any people most likely on their way to the bicycle basement? –When should the heat be turned on?
Tracking objects –Where is the nearest available video projector? –Where is the toilet room? –Where did I leave my mobile computer?
Tracking origins of data Where is the voice recording from yesterdays meeting located? Who should permit that I use the recording? Where do I find the video recording of last weeks lecture?
Tracking un-identified people Where are the located? How did they get in there? What rooms should be sealed to keep them away from any vulnerable inventory?
