Nokia Mobile Data Challenge 2012: your friends determine where you are going

Nokia Research Center Lausanne collected data from smartphones of almost 200 participants over 1+ year and released it for the research community. One striking result is that your friends info is remarkably accurate in determining where you will be in 24 hours.

Nokia Research Center Lausanne and its academic Swiss partners have recently completed a Data Collection Campaign in the Lake Geneva region. Data from smartphones of almost 200 participants was collected in the course of 1+ year.

Nokia Mobile Data Challenge visualization The Mobile Data Challenge (MDC) releases the Lausanne data for the research community. The challenge provides you an opportunity to analyze a comprehensive and relatively unexplored data set including rich social and geographic information. Selected entries will be invited to participate in a workshop organized in conjunction with the Pervasive 2012 conference

Here is the page for Mobile Data Challenge 2012 Workshop (18 - 19.6.2012) which published many interesting papers based on the MDC data.

Technology review story A Phone that Knows Where You're Going describes an algorithm that is accurate within 20 meters when it predicted where any given person would be 24 hours later by using the person's friends locations. 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.
