Method and system for enabling visually impaired computer users to graphically select displayed objects
First Claim
1. A method in a data processing system for enabling a visually impaired user to distinctly visualize individual displayed objects within multiple classes of objects displayed within a graphical user interface environment, said data processing system having a display pointing device associated with a moveable cursor element, a user input device, and an audio output device, said method comprising the steps of:
- associating an audio signal having at least two audible characteristics with each object within a class of objects displayed within said graphical user interface environment, wherein a first of said at least two audible characteristics is common among all objects within a class of objects and unique among all of said multiple classes of objects within said graphical user interface environment, and a second of said at least two audible characteristics is unique among all objects within a class of objects; and
generating a composite audible signal which includes elements of each audio signal associated with each of said objects displayed within said graphical user interface environment, wherein a user may determine how many classes of objects are displayed, and how many objects are displayed within each of said multiple classes of objects within said graphical user interface environment.

Abstract
A method and system for enabling a visually impaired computer user to distinctly visualize individual objects classified among multiple classes of objects within a graphical user interface environment. Within the graphical user interface environment, graphical user interface objects are classified among multiple classes of objects. An audio signal, having at least two audible characteristics, is associated with each object within a class of objects. The first audible characteristic is common among all objects within a class of objects and unique among all objects in other classes of objects. The second audible characteristic is unique among all objects within a class of objects. Thereafter, a composite audible signal is generated for each displayed object which includes audio signals which each include these two audible characteristics. By listening to the first audible characteristic, which is associated with all objects within a particular class, a visually impaired user may be able to determine how many classes of objects are displayed, and distinguish those classes of objects from one another. By listening to the second audible characteristic, which is unique among all audible characteristics associated with objects in the same class, a visually impaired user may be able to determine how many objects are displayed within a particular class, and distinguish those objects from one another. By enabling a visually impaired user to distinguish classes of objects, and the distinguish objects in a particular class, such a user may perform computer operations and utilize a graphical user interface more efficiently.
