Abstract
Although graphical interfaces have provided a host of advantages to the majority of computer users, they have created a significant barrier to blind computer users. To meet the needs of these users, a methodology for transforming graphical interfaces into nonvisual interfaces has been developed. In this design, the salient components of graphical interfaces are transformed into auditory interfaces. Based on a hierarchical model of the graphical interface, the auditory interface utilizes auditory icons to convey interface objects. Users navigate the interface by traversing its hierarchical structure. This design results in a usable interface that meets the needs of blind users and provides many of the benefits of graphical interfaces.
