ABSTRACT:
Disclosed is a computer audio interface having stereo and filtered sound effects to enable blind users to operate a graphical user interface. Stereo balance and incremental filtering are used along separate axes to guide a blind or visually impaired user within an area of a graphical user interface, particularly the client area of a window. As the pointer approaches the left boundary of the client area, the sounds representing the client area come more and more exclusively from the left audio channel. Likewise, when approaching the right boundary, the sound shifts to the right channel. Additionally, as the pointer is moved toward the top of the window client area, the pitch of the sound increases in stepwise fashion.
