The Graphical User Interface Crisis: Danger and Opportunity.
Boyd, Lawrence H.; And Others
This paper examines graphic computing environments, identifies potential problems in providing access to blind people, and describes programs and strategies being developed to provide this access. The paper begins with an explanation of how graphic user interfaces differ from character-based systems in their use of pixels, visual metaphors such as icons and windows, locational and contextual information, and mouse-controlled interaction and random access. The paper then analyzes how much of the benefits of the graphic user interface are shared by blind users. Three stages of access to the graphic user interface are described: (1) the customizing stage; (2) the ssingle-sensory mouseless strategy for providing access to standard text, icons and simple graphics, standard graphical structures, and navigation and control; (3) the multisensory approach with a resurrected mouse, designed to extend compatibility across applications and operating systems and extend access to complex graphics and other benefits. The paper concludes that, as problems are overcome, the resulting computer access systems will provide persons who are blind with new capabilities that were not possible with earlier character-based systems.
