I am happy to congratulate Patricia Kluckner to her PhD defense last friday. She completed her PhD thesis at the ICT&S Center in Salzburg, which I co-supervised besides Prof. Manfred Tscheligi. The thesis is entiteled “Providing Empirical Evidence for Long-term Effects of Persuasive Technology. The Use Case of an Ambient Persuasive Display for Changing Energy Consumption Behavior”. If you are interested in her work she had a full paper (with best paper award!) about the long–term field trials at the Fourth International Joint Conference on Ambient Intelligence 2013.
