Your phone knows where you'll be tomorrow  AUG 20 2012

A team of researchers in the UK have developed a method of predicting where people will be in 24 hours using tracking data from mobile phones.

Studies have shown that most people follow fairly consistent patterns over time, but traditional prediction algorithms have no way of accounting for breaks in the routine.

The researchers solved that problem by combining tracking data from individual participants' phones with tracking data from their friends -- i.e., other people in their mobile phonebooks. By looking at how an individual's movements correlate with those of people they know, the team's algorithm is able to guess when she might be headed, say, downtown for a show on a Sunday afternoon rather than staying uptown for lunch as usual.
