Nowadays, intelligent systems continue to spread through human spaces, either digital, physical, and social. As a result, the nature of human-machine interactions has evolved from isolated transactions to a rich, dynamic, and adaptive coexistence. This new paradigm of interaction demands more than just being user-friendly or efficient; it requires trust, transparency, empathy, and ethical alignment. Machines are more than tools; they are partners, assistants, and, sometimes, autonomous decision-makers, integrated into both critical and everyday environments.
