This book provides a comprehensive overview of the latest research and innovations in the fields of Ambient Intelligence and Ubiquitous Computing. The contributions reflect cutting-edge advances across a wide range of domains, including Ambient, Active, and Assisted Living (A3L) for health and wellbeing; the Internet of Everything (IoE) and sensor ecosystems; and Artificial Intelligence for Ambient Intelligence (AI²). In addition, two special sessions enrich the compilation: Games and Wellness, which highlights the role of affective and serious games in mental and physical health, and Sustainable and Secure Future IoT/IIoT Networks, focusing on challenges in scalability, energy efficiency, privacy, and post-quantum security. Serving as a valuable resource for scholars, professionals, and graduate students, this book fosters cross-disciplinary collaboration and provides a roadmap for future exploration. It not only captures the state of the art but also sets the stage for sustainable, ethical, and human-centered innovations that will shape the future of a smart and interconnected world.
