Public displays for monitoring and improving community wellbeing

In this position paper, we propose a public display app that runs on a University's public display network, for gathering information on student wellbeing, as derived from measuring in-situ heart rate levels. Using a fun on-screen interface, passers-by are invited to measure and anonymously report their stress level. The stress level is measured in-situ through camera-based heart rate estimation and answering a set of self-reporting questions. We foresee the benefits of such a public display app to go beyond personal well-being and extend into community awareness, e.g., by documenting high-stress times such as exam periods. The position paper motivates our work, describes our approach, and outlines research questions and challenges in this domain.
