This book represents the culmination of a fruitful and multi-faceted collaboration between our research teams in Brazil and France. Our journey began in 2019 at the ISPGR International Congress in Edinburgh, when Prof. José Barela and Dr. Cédrick Bonnet discussed shared scientific interests and immediately envisioned collaborative projects. Early interactions via video meetings allowed us to exchange ideas and to share co-developing projects. By 2021, our first joint publication had emerged, and by June 2022, we had co-authored four international articles. Recognizing our productive collaboration, the directors of international relations at University of Lille (ULille) and São Paulo State University (UNESP) invited us to propose a CAPES-COFECUB project for 2023–2026.

This initiative brought together additional colleagues: on the French side, Dr. Laurent Sparrow and Prof. Séverine Casalis from SCALab, and on the Brazilian side, Prof. Sérgio Rodrigues and Dr. Paula Polastri from LIVIA, along with Prof. Fabio Barbieri from MOVI-LAB. Our successful CAPES-COFECUB proposal, “Gaze Behavior and Postural Control in Visual Static and Dynamic Environments”, has supported researchers’ mobility, enabling multiple short-term and extended visits, fostering shared research projects, and stimulating cross-country collaboration. Furthermore, José and Cédrick received Franco-Brazilian chairs in 2023 and 2026, which further strengthened exchange in both sides. Over these years, our teams have produced eight international publications, two recently submitted manuscripts, thirty-seven oral presentations, nine conference posters, media appearances, and several public outreach chapters. This sustained and prolific collaboration laid the foundation for the present book.

The chapters of this book form a coherent exploration of visual perception, postural control, and cognitive function across diverse populations and experimental paradigms. Together, these chapters form a continuous narrative: from fundamental mechanisms of gaze and posture, through cognitive and learning processes, to applied and clinical contexts. The coherence of our work reflects the dynamic, productive, and interdisciplinary nature of our collaboration—a collaboration that has not only advanced scientific understanding but also fostered sustained connections between our research communities in Brazil and France.
