INTERACT is among the world’s top conferences in Human-Computer Interaction. Starting with the first INTERACT conference in 1990, this conference series has been organised under the aegis of the Technical Committee 13 on Human-Computer Interaction of the UNESCO International Federation for Information Processing (IFIP). This committee aims at developing the science and technology of the interaction between humans and computing devices.
The 15th IFIP TC.13 International Conference on Human-Computer Interaction - INTERACT 2015 took place from 14 to 18 September 2015 in Bamberg, Germany. The theme of INTERACT 2015 was "Connection.Tradition.Innovation". This volume presents the Adjunct Proceedings - it contains the position papers for the students of the Doctoral Consortium as well as the position papers of the participants of the various workshops.
In order to adopt sustainable practices and strategies, organizations and individuals need to understand the environmental impact of their behavior and the knowledge about successful resource conservation strategies. Information Systems research and real-time feedback systems in particular can help to bridge this "environmental literacy gap”. In previous work, we presented an IS artifact that presents consumers with behavior-specific information on their energy and water consumption in real time. We found that this approach reduces energy and water consumption by 22%. In this work-inprogress paper, we address the open question of effect persistence in the long term. We analyze 17,612 data points collected in a 12-month field study from 50 households. First analyses indicate that the effect remains stable over time. In line with literature on “data push” systems, we argue that feedback systems should not require an additional step of user action to access the feedback which may be a barrier to longer effect persistence of information systems.
