Abstract: The purpose of mobile Internet information accessibility (MIIA) was to ensure that mobile application content was equally accessible, convenient, and barrier-free for all users, including those with visual impairments.  We systematically review the latest research progress in the field of mobile Internet information accessibility, focusing on the analysis and summary of research achievements in  semantic representation and understanding of mobile GUI, accessibility detection and layout repair. The analysis shows that from traditional heuristic rule methods to deep learning-driven automated tools, related technologies have gradually improved detection accuracy and adaptability, while also revealing challenges in addressing complex dynamic interactions and diverse user needs. We have provided an outlook on  future research directions.  MIIA technologies have significantly improved  the digital experience for visually impaired users, but they still need continuous innovation and optimization  to achieve a truly inclusive digital society.
