ABSTRACT:
The method and system of the present invention may be utilized to enable a blind or visually impaired computer user to graphically select a displayed graphic element within a computer system display. A unique identifiable audible signal is associated with each displayed graphic element. A movable cursor element or pointer is displayed within the computer system display and a composite audible signal is periodically generated in response to the position of the movable cursor element. The composite audible signal preferably includes elements of each identifiable audible signal associated with each displayed graphic element within a predetermined radius of the location of the movable cursor element. In one embodiment of the present invention, each displayed graphic element comprises multiple picture elements and the composite audible signal includes elements of each identifiable audible signal associated with each displayed graphic element having picture elements within a rotatable sector of a circle having its origin at the movable cursor element and a radius equal to the predetermined radius.
