What is Universal Access / Cross Disability Rendering?
This implies choosing a rendering method that best suits client user and respects
- Any hardware constraints -- network bandwidth or screen resolution or client performance
- Any sensory or physical limitations of user
e.g. Visually impaired would prefer audio rich rendering
e.g. Muscularly limited users would need appropriate interfaces
New Cascading Style Sheets can express this but need intelligent renderer to make correct decision and allow user to adjust choices
Further one needs decision at the stage of XML input and not after it has already been rendered into HTML
- HTML expresses “meaning of document” by positioning and other means which are in general impossible to recognize and render in a cross disability fashion
Assume goal is equal and high quality rendering -- do not downgrade material to support cross disability rendering
