Eliciting requirements from citizens

[Context and motivation] The elicitation of requirements is an essential step for requirements engineers to build products and services that fit the needs of users and customers. In environments with connected systems, such as cyber-physical systems or digital ecosystems, several different stakeholders exist that have diverse requirements. One such environment is the smart city district that is the focus of our research project "EnStadt:Pfaff". [Question/problem] One main question in such a context is how to elicit citizens' requirements and needs and how to motivate them to participate in creating digital services and apps that support their lives. [Principal ideas/results] Traditional requirements engineering and elicitation activities (such as workshops) are also relevant in such contexts, but we are also looking for new formats that may-be are more suitable for citizen crowds. We assume that we can learn from other disciplines about their methods and ways, e.g. to motivate citizens. [Contribution] We identified four disciplines and present their benefits for requirements engineering from our perspective. Our goal is to foster further discussions when presenting the corresponding poster.
