This study proposes an immersive storytelling reading platform integrating Generative AI and interactive Augmented Reality (AR) to enhance children’s reading engagement. The platform combines style-transfer-based object detection, LangChain-driven real-time story generation, and Unity-based AR interactions, offering a multi-sensory reading experience via hand tracking and dynamic text. Experiments showed a 21.6% improvement in object detection accuracy, and EEG results revealed increased theta/beta power and suppressed alpha power when using the proposed platform, indicating enhanced attention. These findings highlight the educational potential of interactive reading environments for the digital-native generation.
