The application of interaction design in architectural children’s picture books has attracted much attention. It is a new direction to improve children’s immersive experience for building type recognition. Based on the characteristics and problems of architectural children’s picture books, this paper analyzes the application of extended reality, augmented reality, virtual reality, and interactive multimedia in architectural children’s picture books. It summarizes the interactive design strategies adapted to children’s reading, which not only reduces children’s ‘blind spots’ in the reading process but also provides a clear plan for creators to build a path between children’s cognition and picture book experience to achieve real immersive reading.
