Towards Human-Game Interaction (HGI)

As serious games, as well as entertainment games, evolve along a continuum ranging from analog to digital, including hybrid solutions, the design and role of game interfaces have become increasingly complex and central to the player experience. This position paper proposes a conceptual shift, considering the interface not merely as a structural or aesthetic layer, but as a key mediator between game mechanics and the mental and emotional models formed by players during the game. Building on insights from previous research on interfaces and on player experience, we introduce the Human-Game Interaction (HGI) framework as a lens to systematically analyze how interfaces shape the player’s experience both in serious games and in entertainment games. By referencing design heuristics, the tripartition of the mind, and Gestalt principles, we argue for a holistic understanding of the interface and we offer new perspectives for cross-disciplinary research and practical applications, particularly in the design of serious games where usability and meaningful engagement are essential.
