- AI Content Describer(also: NVDA AI Content Describer)
- AI Content Describer is an add-on for the NVDA screen reader that uses multimodal AI models to generate descriptions of on-screen visual content — images, controls, icons, charts, and arbitrary screen regions — on demand. It gives NVDA users a JAWS-Picture-Smart-equivalent…
- AI for Accessibility(also: AI4A, Artificial Intelligence for Accessibility)
- An umbrella framing used by technology companies and researchers for applications of artificial intelligence — including computer vision, natural language processing, speech recognition, and generative models — intended to benefit disabled users. Common examples include…
- AI-Generated Content(also: AIGC)
- An umbrella term for text, images, audio, video, and other media produced by generative AI systems — especially large language models and diffusion-based text-to-image or text-to-video models — in response to user prompts. AIGC is widely used in creative tooling (backdrop…
- Access-Stabilising Support
- A design framing, introduced by Bhuiyan et al. (2026), that positions AI in Deaf education not as an autonomous translator or replacement instructor but as a mediated tool whose role is to preserve visual access, reinforce teacher-validated signs, and sustain comprehension…

- Anthropomorphism(also: Humanization, Anthropomorphization)
- The attribution of human characteristics, emotions, intentions, or behaviors to non-human entities such as technology, animals, or objects. In assistive technology and conversational AI design, anthropomorphism raises important questions about how human-like an interface should…
- Assistive AI(also: AI for Accessibility, Accessible AI, Accessibility AI)
- Artificial intelligence systems designed specifically to support disabled people in performing tasks, accessing information, or navigating their environments. Examples include object recognition tools for blind users, automatic captioning for deaf users, and predictive text for…
- Assistive Drone(also: Assistive UAV, Assistive Quadcopter)
- A small unmanned aerial vehicle configured to assist a person with a disability — most often a blind or low-vision user — with tasks such as locating objects, navigating unfamiliar environments, scanning distant signage, and previewing walking-path conditions. Compared to…
