Edwards, Alistair, Mynatt, Elizabeth D. and Thatcher, J. (1994): Interface Modeling Issues in Providing Access to GUIs for the Visually Impaired. In: First Annual ACM Conference on Assistive Technologies 1994. p. 157.

“Research in providing access to graphical interfaces for people who are blind has been ongoing for a number of years. After significant work, screen readers for three commercial graphical environments (Macintosh, Windows, OS/2) are now available, and steps to make X Windows accessible are underway. But many issues about how a blind person might want to interact with an accessible graphical interface are still unresolved. Are concepts such as drag and drop, iconified windows and direct manipulation appropriate for nonvisual interfaces? If so, how can they be effectively conveyed to people who have never experienced working with graphical interfaces? At the heart of the matter is the question: What is the model of the user interface that the screen reader is providing access to? Even the name "screen reader" implies a certain way of thinking about the graphical interface. A number of different approaches have been utilized in various commercial screen access systems and research prototypes. These systems have opened some doors for nonvisual interaction with a graphical interface, but other doors remain closed. In this session, we will not discuss underlying implementation strategies, although these are interesting in their own right. Rather, we will focus on the designer's conceptual model of the graphical interface, and how this model is conveyed to the (blind) user of the nonvisual interface.”
