Abstract: In order to solve the interactive problem of children's electronic picture books and realize the design and production for children's reading, based on the dual coding theory, a picture book design method an IOS (Input Output System) platform technology is proposed, which introduces digital media, animation and a variety of production methods such as sound effects realizing a new type of electronic picture book with better interactivity. Through the mobile device based on the IOS system, the visual display and intelligent recommendation of children's picture book knowledge are realized. Through verification and analysis, the system solves the problem of lack of interactivity of children's electronic picture books, and improves the accuracy of intelligent recommendation of children's electronic picture books. It can be used as a reference for the design and development of children's picture books in the future.
