Along with
the adoption of accessible information encodings at the server
end, there is a corresponding need to develop accessible
information clients. Currently, there is no real effort in this
direction; visually impaired users typically make do by getting
a screen-access program to speak what is displayed by a
visually oriented client. Though this approach works for simple
documents containing minimal visual layout, the approach breaks
down when dealing with more complex documents,
e.g.,tax forms, technical material and other sources
of highly structured information.
The above breakdown occurs because all of the structural
information is displayed by a visually oriented client by using
visual layout cues which are lost when the display is directly
spoken by a speech synthesizer or enlarged using a larger font.
