Affective computing and human-centric modelling represent an exciting frontier in technology, bridging the gap between human emotions and digital interactions. This books contains contributions to this field of research by mostly focusing on emotional awareness and designing systems that genuinely prioritise user experiences, to create a future where technology enriches human existence, amplifying our emotional capacities rather than overshadowing them. As the field evolves, embracing ethical considerations and fostering collaborative innovation will be paramount in ensuring that technology remains a positive force in our lives.
