This study aims to systematically examine the mechanisms through which open-world game design elements influence users’ Health of Mind (HM) and their psychological recovery, thereby constructing a user-centered framework for mental health–promoting game design. In recent years, video games have evolved beyond entertainment to become multidimensional media combining emotional regulation, stress relief, self-expression, and social connection. Among these, open-world games—characterized by free exploration, immersive interaction, and systemic openness—are considered especially conducive to psychological healing and emotional restoration. Based on this context, the study analyzes the structural relationships between open-world game design elements and mental health experience to reveal their positive psychological effects and potential applications. Grounded in User-Centered Design (UCD) and Emotional Design theories, this study develops an integrated dual-layer research model encompassing both functional and psychological dimensions. The UCD dimension focuses on how design elements such as control, achievement, and liberation enhance users’ operational efficiency and self-efficacy, while the Emotional Design dimension examines how immersion, visual healing, and social expression influence users’ emotional regulation, sensory engagement, and social identity. Using this dual structure, the study establishes a multi-dimensional model of “game design elements → mental health experience.” Previous studies have shown that gaming can improve emotional regulation and reduce psychological fatigue (Reinecke, 2009; Seligman, 2011; Csikszentmihalyi, 2014), but most focused on general or single-sensory experiences. In contrast, this study empirically analyzes the complex interactional environment of open-world games and their integrated mental health experience design elements. A questionnaire survey was conducted with participants experienced in open-world games, comprising 36 items covering six dimensions of mental health experience and six corresponding design factors. Data were analyzed using SPSS through factor analysis, reliability testing, correlation analysis, and multiple regression analysis. Results show that self-directed structures and freedom of exploration significantly enhance users’ sense of liberation and control, reducing stress and improving emotional stability. Progressive reward systems and visual feedback strengthen achievement and self-efficacy, while visual elements such as color, lighting, and natural scenery promote healing effects. Social interaction and emotional sharing enhance belongingness and social support. Overall, open-world game design elements interact dynamically across cognitive, emotional, and social domains, forming a cyclical “liberation–control–achievement–immersion” structure that promotes psychological recovery and emotional regulation. This study empirically demonstrates the potential of open-world game design to enhance mental health experiences and proposes a user-centered, emotionally integrated framework for mental health–oriented interactive systems. The findings provide a theoretical and methodological foundation for future developments in digital healthcare, psychological recovery content, and metaverse-based interactive environments.
