“The Throne is Mine” is an innovative augmented reality (AR) card game designed for children aged 4–12, that explores the educational experience of hybrid physical-digital card play. By integrating 3d character models with traditional card gameplay, we examined how AR technology can enhance children’s memory retention and decision-making ability while maintaining the existent benefits of conventional tabletop games. Our implementation used Unity 3d and Vuforia for robust image recognition, focusing on creating age-appropriate UI based on Piaget’s cognitive development framework. Preliminary testing with children revealed promising engagement levels, with most of the children responding more positively to this mixed format, showing increased excitement during AR-triggered animations compared to non-AR cards. Key challenges included improving gesture controls for younger users and ensuring consistent AR tracking across varying lighting conditions. This work contributes to the growing conversation around AR’s educational applications by demonstrating how thoughtful integration of digital elements can enhance, rather than replace, physical play experiences. We identify specific design considerations for child-focused AR applications that prioritize both engagement and educational outcomes.
