The rapid convergence of AI and digital media technologies is blurring the boundaries between the virtual and the real, giving rise to new forms of cultural existence. Among them, virtual idols—digital personae that combine human-like emotional expressions with algorithm-based technologies—create emotional bonds and immersive experiences with users through visual media and interactive platforms. This phenomenon represents not merely technological advancement but also a socio-cultural shift that reflects changes in emotional exchange, self-identification, and cultural consumption patterns in the digital generation. In recent years, the virtual idol industry has expanded into entertainment, gaming, advertising, and brand collaborations, evolving into a comprehensive content ecosystem. However, despite this industrial growth, academic research has yet to sufficiently address how users’ psychological factors and value perceptions influence behavioral decision-making. Existing studies have tended to focus on surface-level factors such as fandom formation or technological implementation, with limited integrated analysis of users’ cognitive responses, value evaluation processes, and the internal mechanisms that lead to emotional immersion and continuous behavior. To bridge this gap, the present study identifies users’ cognitive characteristics of virtual idol engagement as a core concept and examines how four factors—sensory stimuli, character attractiveness, content quality, and brand collaboration—affect users’ perceived values (emotional, social, and functional value). In addition, the study empirically verifies whether these perceived values play a mediating role in the formation of users’ behavioral intentions. Employing a quantitative research design, a structured survey was conducted with individuals who had prior experience engaging with virtual idols. A total of 819 valid responses were collected, and correlation analysis, reliability and validity testing, multiple regression analysis, and Sobel mediation testing were performed based on data measured using a five-point Likert scale. The analysis revealed that the four cognitive characteristics significantly and positively influenced all three dimensions of perceived value, which in turn exerted significant positive effects on behavioral intention. Notably, emotional value demonstrated the strongest impact on behavioral intention, indicating that emotional value serves as a key driving force behind users’ engagement with virtual idols. Furthermore, cognitive characteristics were found to indirectly enhance users’ sustained interest, voluntary participation, purchase intentions, and recommendation intentions through the mediating role of perceived value. Theoretically, this study overcomes the limitations of prior research that examined technological or emotional factors in isolation and systematically clarifies the multi-layered pathway linking cognitive characteristics, perceived value, and behavioral intention. By presenting an integrated process through which sensory stimuli, character appeal, content quality, and brand collaboration transform into behavioral responses via emotional experience, social interaction, and functional benefits, the study offers a more comprehensive and sophisticated explanatory framework for virtual idol user behavior. From a practical perspective, the findings provide strategic implications for virtual idol operations. In terms of cognitive characteristics, operators should enhance visual symbolism and voice recognition to improve users’ sensory identification, and strengthen emotional immersion and identity projection through stable character personalities and coherent narratives. Maintaining high content quality and continuous updates can stabilize user expectations, while culturally aligned brand collaborations can reinforce overall evaluation and trust. In terms of perceived value, operators should enhance emotional value through character storytelling and deep interactions, strengthen social value through community structures, fan co-creation, and participatory brand collaborations, and improve functional value by increasing content utility and platform stability. The interaction of these pathways effectively fosters long-term engagement, immersion, and behavioral intention, contributing not only to the commercial value of virtual idols but also to the sustainable development of the virtual idol ecosystem. Overall, this study empirically reveals how users’ cognitive characteristics and perceived values shape long-term engagement and immersion in virtual idol interactions, providing a theoretical and practical foundation for digital content experience design and user-centered operational strategies. Beyond commercial efficiency, the findings offer strategic insights into strengthening emotional and social connections between humans and virtual entities and fostering a sustainable digital ecosystem.
