They want to tell us: Attention-aware Design and Evaluation of Ambient Displays for Learning

This paper explores the interaction between users and ambient displays and the evaluation thereof in a learning context. A formative design study examined the user attention towards ambient displays as well as the influence of different display designs. Experimental prototypes were varied on two design dimensions, namely representational fidelity and notification level, and deployed on a university campus. For the evaluation a combined approach using quantitative attention data as well as qualitative assessment methods was used. The results show a high degree of user interest in the displays over time, but do not provide clear evidence that the design of the displays influences the user attention. Nevertheless, the combination of quantitative and qualitative measurement does provide a more holistic view on user attention. The gathered insights can inform future designs and developments of ambient displays also beyond the learning context.
