************************************************ CALL FOR CONTRIBUTIONS Workshop on “From Data to Transformative Change: Designing Interactive Systems for Citizen Science Empowerment”, organized at ACM SIGCHI Designing Interactive Systems Conference (DIS) 2025, to be held in Funchal, Madeira (Portugal), on July 05, 2025. Website: https://sites.google.com/view/cs-dis-25/home Contact: catia.prandi(a)unibo.it ************************************************ ***Scope*** Citizen Science (CS) is a research approach in which scientists and everyday people collaborate to address a research problem. Advancements in digital technologies have significantly expanded the reach of CS by enabling large-scale data collection and collaboration. In addition to its scientific benefits, CS enhances participants' science literacy, fosters public engagement, and promotes collaborative problem-solving. Despite this being true, we believe that the true potential of CS has not yet been fully explored as a collaborative practice for transformative change. With this in mind, we planned a one-day workshop as a forum for critical discussions and reflections on the role of HCI researchers, designers, and practitioners in designing CS-empowered interactive systems for increasing awareness about social good and societal issues and promoting concrete actions and behavioural change, from data to sustainable futures. ***Submissions*** Participants interested in joining the workshop can submit either a late-breaking work abstract/short paper (2 to 4 pages, plus references, using the ACM single-column template) or a motivation statement (1–2 pages, including references, using the ACM single-column template). The paper should include the authors' names. To submit your contribution, simply send an email to: catia.prandi(a)unibo.it, with the Subject: “CS DIS workshop submission" by June 10 (AoE). You will receive an answer by June 16. ***Workshop format*** A one-day workshop where participants will have the possibility to reflect on and discuss the main open challenges still affecting the design of CS-empowered interactive systems, and to prototype, exploiting data physicalization and co-design, solutions that focus on a specific real-world challenge as presented by experts of the Madeira Island that offers a unique ecosystem to spark reflections on the interplay between sustainability, technology and CS. As for the main conference, the workshop will take place as a full in-person event. ***Important dates*** Contributions submission deadline: June 10, 2025 Notification of acceptance: June 16, 2025 Workshop (at DIS 2025): July 05, 2025 ***Organizers*** Catia Prandi (University of Bologna, Italy) Christothea Herodotou (Open University, UK) Mara Dionisio (University of Madeira, Portugal) Neal Reeves (King's College London, UK) Lizette Reitsma (Malmo University, Sweden) Simone Mora (MIT, USA) ***Venue*** The workshop will be in conjunction with the ACM SIGCHI Designing Interactive Systems Conference (DIS) 2025 to be held in Funchal, Madeira (Portugal) from July 05 to July 09, 2025. _________________________________________ Catia Prandi, PhD.
