The CV4A11y Workshop focuses on how new advances in vision foundation models and generative AI can help improve accessibility for people with disabilities. These technologies have great potential, but there are still important challenges, such as bias, limited data, lack of explainability, and real-world deployment issues. This workshop brings together experts in computer vision, AI, human-computer interaction, and accessibility to share new ideas, discuss open problems, and explore future directions. Our goal is to support the development of AI-powered tools that are more inclusive, useful, and effective in improving daily life for individuals with disabilities.
