Network 1,000 new DTU students are being invited to take part in an experiment that uses smartphones for real-time mapping of social networks.

Facebook has generated extensive new knowledge about how and why friendships arise. But people also meet face-to-face, talk on the phone, send text messages and communicate on- and offline in many other ways. But what does a social network look in real time? Using smartphones, a team of researchers from DTU and University of Copenhagen are exploring this very question.

The experiment began in 2012 when 200 students from four DTU study programmes were given smartphones to map their movements, phone calls, text messages, Facebook updates, etc. The information is then gathered and stored in a database.

Together with a group of researchers from University of Copenhagen, the study will now be expanded to include a further 1,000 students who will be recruited from among new DTU students starting in autumn 2013.
As part of the experiment, the participants will receive a smartphone which they can keep as long as they are part of the study. Privacy is an important element and all personal information is therefore kept anonymous. On a ‘data dashboard,’ participants can see all the information gathered about them.

Heading the study is Associate Professor Sune Lehman from DTU Compute—which in 2011 received a DKK 7m grant from the Villum Foundation towards the study whose official title is ‘Ultra-detailed Complex Networks’.
