This is a tremendously important paper for insight into how computer scientists are trying to model and sense human concepts of place... In some ways, its a computerization of Kevin Lynch's mental mapping methods from the 50s and 60s (e.g. "Good City Form")

Location-enhanced mobile devices are becoming common, but applications built for these devices find themselves suffering a mis- match between the latitude and longitude that location sensors provide and the colloquial place label that applications need. Conveying my loca- tion to my spouse, for example as (48.13641N, 11.57471E), is less infor- mative than saying ³at home.² We introduce an algorithm called Beacon- Print that uses WiFi and GSM radio fingerprints collected by someone¹s personal mobile device to automatically learn the places they go and then detect when they return to those places. BeaconPrint does not au- tomatically assign names or semantics to places. Rather, it provides the technological foundation to support this task. We compare BeaconPrint to three existing algorithms using month-long trace logs from each of three people. Algorithmic results are supplemented with a survey study about the places people go. BeaconPrint is over 90% accurate in learning and recognizing places. Additionally, it improves accuracy in recogniz- ing places visited infrequently or for short durationsa category where previous approaches have fared poorly. BeaconPrint demonstrates 63% accuracy for places someone returns to only once or visits for less than 10 minutes, increasing to 80% accuracy for places visited twice. --- You are currently subscribed to telecom-cities as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED] Manage your mail settings at http://forums.nyu.edu/cgi-bin/nyu.pl?enter=telecom-cities RSS feed of list traffic: http://www.mail-archive.com/telecom-cities@forums.nyu.edu/maillist.xml
