*** Second Call for Contributions *** 20th International Conference on Persuasive Technology (PERSUASIVE 2025) May 5-7, 2025, 5* St. Raphael Resort and Marina, Limassol, Cyprus https://2025.persuasivetech.org (*** Proceedings to be published by Springer in LNCS ***) In a world in which technology is increasingly present in people’s lives, and changing human behavior and attitudes is often the key to solving many societal and personal problems, studying how technology might be used to influence humans (in their behavior, attitudes and information processing), is paramount. Persuasive Technology is a vibrant interdisciplinary research field, focusing on the design, development and evaluation of interactive technologies aimed at influencing people’s attitudes and/or behaviors through persuasion, but not through coercion or deception. The research community aims at enriching people’s lives in various domains such as health and sustainability by supporting people in setting and achieving their own goals, thus helping them change their behavior. The 2025 conference will be hosted in Limassol, Cyprus at the 5* St. Raphael Resort and Marina. The previous successful conferences have been organized in Wollongong, Limassol, Eindhoven, Stanford, Oulu, Claremont, Copenhagen, Columbus, Linköping, Sydney, Padua, Chicago, Salzburg, Amsterdam, and Waterloo. The conference series seeks to bring together researchers and practitioners from industry and academia working with various topics of persuasive technology. We welcome the following categories of papers and extended abstracts: • Technical papers that introduce novel persuasive technology approaches and solutions alongside evidence of their potential. • Empirical studies which seek to provide evidence and explanation of methods, principles and theories in persuasive systems. • Conceptual-theoretical papers which primarily seek to contribute to the general understanding of the field’s core themes and specificities. • Other papers, e.g. literature reviews or experience reports. SCOPE The scope of the conference includes (but is not limited to) the following topics: • Persuasive systems’ design • Behavior change support systems • Interaction with persuasive systems, interfaces, visualization • Interactive agents in persuasive systems • (Generative) AI for persuasive technology • Tailored and personalized persuasion • Gamification for persuasion • Evaluation and validation of persuasive applications • Fitting methods for development, evaluation and implementation of persuasive systems • Optimizing engagement with persuasive systems • Software architectures and technical infrastructures for persuasive systems • Smart environments, e.g. IoT, and persuasion • Digital Marketing, eCommerce, eTourism and SMART ecosystems • Motivational, cognitive and perceptual factors in persuasive technology • Application domains for persuasive technologies such as safety, healthy living, sustainable behaviors, learning and training, marketing and commerce, work environments, organizations • Positive technology • Humanizing and/or dehumanizing effects of persuasive technology • Values and ethics in persuasive technology • Privacy, perceived security and trust in persuasive technology • Resilience and counter-persuasion • Detecting persuasive strategies in social media posts • Encouraging adherence to safety measures in pandemic situations Questions that we hope to be addressed include, but are not limited to: • How to recognize and demonstrate the real life effects of persuasive technology on people’s attitudes and behaviours? • How to conduct studies that not just show their effectiveness but are also able to explain in more detail why a design or intervention works? • How to design an evaluation study so that it yields insights that are applicable to other designs or interventions? • How theoretical insight can help improve application and/or intervention planning and design? • How can design and intervention studies improve theory? SUBMISSION TYPES Regular Papers This format is suitable for original research, which is completed work at the time of submission and, regardless of the length of the paper, is a self-sufficient scientific contribution. Papers can be full papers (12 pages, excluding references) or short papers (6 pages, excluding references) in Springer LNCS format, and describe work not presented, published or simultaneously submitted elsewhere. Accepted papers will be included in the Springer LNCS conference proceedings and be devoted a timeslot for oral presentation. Selected papers will be invited for submission to Behaviour & Information Technology journal (Taylor & Francis). Extended Abstracts We also welcome extended abstract submissions to showcase the results of already conducted studies where authors do not wish to publish them as regular papers in the conference proceedings but rather present them at the conference for discussions that can shape the final version (that may be submitted elsewhere later). The studies will be also be devoted a timeslot for oral presentation in a special session. Extended abstracts must not be more than 2 pages in CEUR format (including references). Accepted abstracts will be included in the adjunct conference proceedings (CEUR Workshop Proceedings, 1 column style, see here). Selected papers in this category, based on their quality, level of timeliness and relevance, and completion, will also be invited for submission to Behaviour & Information Technology journal. Poster Presentations This format is suitable for descriptions of smaller studies, project outlines, literature reviews or work-in-progress. Authors should submit a 2-page abstract in CEUR format (1 column style). Accepted posters will be included in the adjunct conference proceedings (CEUR Workshop Proceedings). Posters will be displayed and presented during a dedicated session of the conference. Demonstrations and Artefacts The Persuasive 2025 track on Demonstrations and Artefact is intended to foster discussion and exchange of ideas among researchers and practitioners from academia and industry by demonstrating or presenting hardware and software products or artefacts, including those in virtual settings (e.g., simulation systems, VR, and games), that range from early research prototypes to mature production-ready systems. The contribution should be the result of original, innovative work, including solving novel technical or research problems, and/or creating novel individual or industrial UI/UX. Accepted demonstrations or presentations shall be presented live during the conference. Doctoral Consortium Papers The Doctoral Consortium is a special session of the conference where PhD students can receive advice in a constructive atmosphere. Students present and discuss their research with other PhD students and a panel of established researchers in the area of persuasive technology. Students interested in participating in the Doctoral Consortium should submit a 4-page abstract in CEUR format (1 column style) describing their research question, its position with respect to the state of the art, their research plans and methodology, ideas, and results achieved so far. Accepted abstracts will be included in the adjunct conference proceedings (CEUR Workshop Proceedings) unless opted out by the student. Workshops and Tutorial Proposals Workshops are meant to gather a number of people to work interactively on an emerging topic and exchange ideas. Tutorials are intended to help people attending the conference organize a related scientific meeting on a specific topic or instruct on a specific practice. Approved workshops and tutorials will be announced on the conference website. Tutorials and workshops will take place during a half- or full-day session before the conference. If you want to organize a workshop, please submit a proposal as a maximum 4-page description in Springer LNCS format (https://www.springer.com/gp/computer-science/lncs/conference-proceedings- guidelines), including a description of the topic, motivation, organization (including the list of organizing members, how the organizers will form a program committee, duration of the workshop and mode of delivery: in-person/hybrid), expected outcome, and supporting materials (if applicable). Workshop and tutorial descriptions will be included in the adjunct conference proceedings (CEUR Workshop Proceedings) https://ceur-ws.org/HOWTOSUBMIT.html. Workshop organisers must commit to creating their Call for Papers and their website within one week of the notification. Please email your proposal by December 01, 2024, to the workshop chairs: Wenzhen Xu (wenzhen.xu@r.hit-u.ac.jp), Rhoda Abadia (Rhoda.Abadia@unisa.edu.au), and Kaoru Sumi (kaoru.sumi@acm.org). The organizing committee will review the proposals and communicate the results by December 15, 2024.
