Florian Lettner attended the Doctoral School at the 2013 ACM International Joint Conference on Pervasive and Ubiquitous Computing (UbiComp 2013) from September 8-9 in Zurich, Switzerland. He presented his ongoing doctoral thesis with the working title “A Generic Concept for Task-driven Remote Usability Testing in Mobile Ecosystems”. The conference is a merger of the two most renown conferences in the field, Pervasive and UbiComp, and thus offers a single venue for the leading worldwide research in Pervasive and Ubiquitous computing.
