Information Clients

  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.
