Algorithm Uses Your and Friends Locations to Predict Your Future Location (within 20 meters!)

Researchers in the U.K. have come up with an algorithm that follows your own mobility patterns and adjusts for anomalies by factoring in the patterns of people in your social group (defined as people who are mutual contacts on each other's smartphones).

The method is remarkably accurate. In a study on 200 people willing to be tracked, the system was, on average, less than 20 meters off when it predicted where any given person would be 24 hours later. The average error was 1,000 meters when the same system tried to predict a person's direction using only that person's past movements and not also those of his friends, says Mirco Musolesi, a computer scientist at the University of Birmingham who led the study. 

The study for a Nokia funded competition, the Mobile Data Challenge, finally gets to the idea that people have regular orbits and regular social connections. While the study was small and involved participants described as "fairly predicatable" over a limited geographic area, I suspect there's something to this. The team won 3000 euros for its efforts.
