Communication Accessibility
- Sign language
- Captions
AI-powered tools that help people learn, look up, and understand American Sign Language, and richer captions that convey emotion and non-speech information for d/Deaf and hard-of-hearing viewers.
Our lab studies and designs human–AI systems that make communication, information, and public services accessible.
Projects span sign language and captioning technologies, reading supports, accessible data visualizations, and civic AI chatbots. They center the experiences of people with disabilities and their communities.
