- Conference PaperThe Novelty Effect in Large Display Deployments – Experiences and Lessons-Learned for Evaluating Prototypes(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Exploratory Papers, 2018) Koch, Michael; von Luck, Kai; Schwarzer, Jan; Draheim, SusanneThis exploratory paper addresses the novelty effect in large display field deployments by combining findings from both the existing body of knowledge and our own research. We found that the novelty effect is prevalently present on two occasions: (a) immediately after a new system is deployed in a new environment, and (b) in reoccurring situations, when changes are made to an existing system. Both instances share similarities such as a system’s higher usage during a particular time frame. However, we also observed that their individual reasons to occur are multifaceted. The present work’s main contribution is twofold. Firstly, the paper outlines related literature regarding the novelty effect, particularly in CSCW and HCI. Secondly, the paper illustrates the effect’s complex nature and suggests explicit means that should be considered in related research endeavors.
- Conference PaperTowards Methodological Guidance for Longitudinal Ambient Display In Situ Research(Proceedings of 17th European Conference on Computer-Supported Cooperative Work, 2019) Schwarzer, Jan; von Luck, Kai; Draheim, Susanne; Koch, MichaelField deployment research represents a promising way for understanding how technology is utilised in the wild. It gained relevance in both HCI and CSCW, and allows, for instance, to investigate how technology is socially embedded in real world contexts. However, such enterprises are considered complex in nature due to continuously changing conditions such as practices surrounding technology. In situ research has yet to gain momentum, leaving researchers with little theoretical guidance. In response, the present paper proposes the application of classic grounded theory in longitudinal field deployment studies for ambient displays. We argue that the methodology is a valuable choice in cop- ing with the challenges surrounding in situ evaluations and simultaneously ensures methodological rigour. This paper contributes a practical systematisation of the methodology’s two core concepts, namely constant comparison and theoretical sampling. It sheds light on their exemplary application in investigating quantitative interaction data in the early stages of our ongoing research. With that, we hope to encourage future research and provide a first stepping stone towards developing methodological guidance for evaluations of ambient displays in the wild.
