In the talk we will first describe a large-scale deployment-based research study that logged detailed application usage information from over 4,100 users of Android-powered mobile devices. Our contextual findings include those related to time of day and location. For instance, we show that news applications are most popular in the morning and games are at night, but communication applications dominate through most of the day. Based on these findings we will present some hypotheses, that could lead to novel mobile applications and future mobile devices. We conclude with an outlook on early prototypes of future mobile devices that could adapt their shape according to the applications they are running.


Johannes Schöning Johannes Schöning is a professor of computer science with a focus on HCI at Hasselt University, working within the Expertise centre for Digital Media (EDM) – the ICT research Institute of Hasselt University. In addition, he is a visiting lecturer at UCL London within the Intel Collaborative Research Institute for Sustainable Cities. Previously, Johannes worked in industry and at the Innovative Retail Laboratory of the German Research Centre for Artificial Intelligence (DFKI) in Saarbrücken. During his time at DFKI, he received a PhD in Computer Science at Saarland University (2010) and a Master in Geoinformatics at the University of Münster at the Institute for Geoinformatics (2007). His research interests are new methods and novel mobile interfaces to navigate through spatial information. In general, he develops, designs and tests user interfaces that help people to solve daily tasks more enjoyable and/ or effectively. This includes the development of mobile augmented reality applications, interactive surfaces and tabletops and other “post desktop” interfaces. His research and work was awarded with several prices and awards, such as the ACM Eugene Lawler Award or the Vodafone Research Award for his PhD. He is listed in the "Innovators under 35" of the German Technology Review in 2013. In addition, Johannes serve as a junior fellow of “Gesellschaft für Informatik”.
