SubRosa: Supporting a proper learning atmosphere through subtle cues with immediate feedback

Paper in proceeding, 2014

SubRosa is a persuasive ambient display system designed to reduce sound levels in areas used for quiet study. We have constructed a high-fidelity prototype that visualises ambient noise levels, in this case as a rotting tomato. SubRosa is different from similar systems in that it uses immediate feedback and targets a dynamic user group with a high member turnover. An experience study we conducted in two different locations showed positive influence on ambient noise conditions. Based on the study results, we discuss insights into the design of persuasive ambient displays, the effectiveness of our approach, and types of ambient feedback that could be used in similar systems. By comparing the experience study results, we show how immediate feedback for ambient displays is suitable for environments with dynamic user groups. © 2014 Springer International Publishing.
