To achieve a level of ‘Extreme’ Citizen Science, a narrow disciplinary knowledge is not enough. Therefore, an interdisciplinary research group has been created that is capable of engaging communities, that can overcome the technical and human-technology interaction challenges, understand the issues in the science of Citizen Science, and has the ability to deliver practical solutions. We are drawing on the knowledge of geographers, computer scientists, human-computer interaction experts, designers, electronic engineers, ecologists and other fields. We aim to change the current state of the art by focusing on participatory sensing, monitoring and modelling activities, where decision on what is measured and the analysis are carried out at the community level, and lead to decisions and actions at that level. We will develop the underlying technologies to enable lay users to understand and manage their environment using established scientific methods and models…more.
