Audio Description, A Visual Assistive Discourse
Individuals who are visually impaired and blind face challenges in accessing many types of texts including television, films, textbooks, software, and the Internet because of the rich visual nature of these media. In order to provide these individuals with access to this visual information, special assistive technology allows descriptive language to be inserted into the text to represent the visual content. This study investigates this descriptive language. A thesis written by Philip Piety, Georgetown University, in 2003.
