*SECOND CALL FOR PAPERS: 14th International Workshop on Behavior Change Support Systems – BCSS 2026* Hakodate, Japan https://bcssworkshop.wordpress.com/ The 14th Int’l Workshop on Behavior Change Support Systems – BCSS 2026 – will be held in conjunction with the 21st International Conference on Persuasive Technology in Hakodate, Japan. *Important dates* Submission deadline: January 15, 2026 Notification to authors: February 5, 2026 Final version deadline: February 20, 2026 Event: March 10, 2026 *Description of the event* The Behavior Change Support Systems workshop, BCSS, organized in conference style, builds around the concept of information systems specifically designed to help and support attitude or behavior change in individuals or groups. Information technology has the capacity to enable smart, virtual persuasive environments that provide multimodal cues and psycho-physiological feedback for an individual’s change by strengthening emotional, social, and physical presence. Numerous technologies and applications have been developed over the past decades, showing promising results in motivating and supporting people in domains such as health and wellbeing. As a research field, persuasive technology continues to be a crucial link between different sciences, necessitating a comprehensive understanding of systems supporting behavior change and an interdisciplinary approach to their design, implementation, and evaluation. However, the full potential of these technologies shaping behaviors and tracking the progress and outcomes of interventions have not been used to their full potential. This workshop series seeks to shed new light on the various processes of behavior change support systems. Yet, although human-computer interaction is social in nature and people may even see software applications as social actors, it is still surprisingly unclear how these interactions end-up shaping our attitudes and behaviors. Additionally, the pitfalls and potential drawbacks are not yet fully understood. As people interact with these technologies, they, at the same time, keep modifying their environment as well as adjust their goals during use time. This seems to indicate that digital persuasion is not a one-time, isolated event but rather an ongoing, dynamic process. Since its inauguration, the BCSS workshop has emphasized the highly interdisciplinary approach required for developing and implementing such systems. The workshop provides a scholarly forum connecting researchers, practitioners and experts from various scientific disciplines such as information systems science, human-computer interaction, industrial design, and psychology, and application domains such as information security, sustainability, and medicine. This year’s event especially seeks, but is not limited to, submissions that discuss innovative approaches and cutting-edge technologies such as artificial intelligence (AI) and metaverse in the design, development and implementation of BCSS. The ultimate goal is to create efficient and flexible BCSSs that promote long-term positive user experience. *Paper submission* Scientific papers in two categories are sought for (the submission can be either in CEUR or Springer LNCS format): · Full papers (max 16 pages) · Short papers (5-9 pages) All the papers will be reviewed by at least two reviewers. Accepted papers will be published via *CEUR Workshop Proceedings*. Authors presenting and publishing an accepted paper in the proceedings are expected to register and participate in the Persuasive Technology conference. *Additional information* For more information about the workshop and the conference, please visit the links: - BCSS workshop web site: https://bcssworkshop.wordpress.com/ - Persuasive Technology conference web site: https://2026.persuasivetech.org/ For any questions regarding the event, please contact the Organizing Chair: Sharon.Nabwire@oulu.fi *Conference Committees* *General and Program Chair* Oinas-Kukkonen Harri, University of Oulu, Finland *Organizing Chair* Nabwire Sharon, University of Oulu, Finland *Program Committee* Agyei Eunice, UK Centre for Ecology and Hydrology, United Kingdom Arakawa Yutaka, Kyushu University, Japan Armayones Ruiz Manuel, Universitat Obertade Catalunya, Spain Brinkman Willem-Paul, Delft University of Technology, Netherlands Burri Gram-Hansen Sandra, Aalborg University, Denmark Condori Fernandez Nelly, Universidad Santiago de Compostela, Spain Ekpezu Akon, University of Oulu, Finland Fraser Kieran, PayPal, Ireland Guadagno Rosanna, University of Oulu, Finland Haque Sanaul, LUT University, Finland Iyengar Sriram, University of Arizona, United States Langrial Sitwat, National University of Sciences and Technology, Pakistan Oyibo Kiemute, York University, Canada Ren Xipei, University of Macau, China Sharma Nikita, University of Twente, Netherlands Sittig Scott, University of Louisiana, United States Vlahu-Georgievska Elena, University of Wollongong, Australia Yetim Fahri, FOM University of Applied Sciences, Germany
