A Close Look at Citizen Science Through the HCI Lens: A Systematic Literature Review.

In this paper, we present a systematic literature review of Citizen Science (CS) research projects with a focus on Human-Computer Interaction (HCI) and on the modalities in which CS is employed in this field. The query was conducted in March 2022 and provided us with 929 items, of which 646 were research articles. Through the usage of the PRISMA flow diagram, we included 27 papers in our survey. We aim to depict the state of the art regarding CS projects that are directly supported and explicitly defined by the HCI community. We compared the studies on variables like the field of interest and the impact area. We present the mutual interests of CS and HCI, the tools, and the methods that are employed to address these projects. Eventually, we conclude by pointing out some reflections on the value that can sprout from properly employed CS in HCI research.
