The transition from Industry 4.0 to Industry 5.0 emphasizes a paradigm shift from automation-centric production toward a more human-centered industrial ecosystem. Within this context, Human-Robot Collaboration (HRC) has emerged as a key enabler, allowing operators and collaborative robots (cobots) to share tasks in a safe, flexible, and productive manner. However, assembly operations often remain cognitively demanding, error-prone, and monotonous for human workers, which can negatively affect both efficiency and well-being. Gamification which by definition is the application of game design principles in non-game contexts has recently attracted attention as a promising strategy to enhance user engagement, motivation, and overall work experience.
