Storybooks play a positive role in auxiliary interventions for children with autism spectrum disorder (ASD). However, each child has unique cognitive levels and interests, making it difficult for parents and special education teachers to find suitable books. Based on professional practice and academic validation, the product team of the Al tool for picture books for children with ASD, guided by autism intervention experts, fine-tuned and optimized the AI model. Using an agent architecture, the system automatically generates audiovisual storybooks from a brief synopsis, greatly simplifying the process for parents and educators.
