SensibleDTU Publications

From September 2013 to February 2016 my group – in collaboration with a consortium of researchers from university of copenhagen – ran a large experiment called SensibleDTU based on data collection using smartphones.

Using the smartphone sensors, we collected networks of who met in physical space (via Bluetooth, GPS, WiFi), who called each other on the phone or sent text messages, who were friends on Facebook and how they interacted on that platform. We also collected data on how people move around in space (via GPS), and asked a large number of questions on demographics as well.

This page provides an over view of publications from this study (or at least the ones I’m involved in). Below, I have grouped them thematically and ordered them in reverse chronological order within each theme (this page was updated November 2016).

Overview

The main reference for the study describes the dataset, our motivations, and also talks a bit about user privacy. (This is the one to cite if you want to refer to the study in general.)
