From Authoring Tool
Accessibility Guidelines 1.0 (2000-02-03) |
Glossary for this
source
Content is "equivalent" to other content
when both fulfill essentially the same function or purpose upon
presentation to the user. Equivalent alternatives play an important
role in accessible authoring practices since certain types of
content may not be accessible to all users (e.g., video, images,
audio, etc.). Authors are encouraged to provide text equivalents
for non-text content since text may be rendered as synthesized
speech for individuals who have visual or learning disabilities, as
braille for individuals who are blind, or as graphical text for
individuals who are deaf or do not have a disability. For more
information about equivalent alternatives, please refer to the Web
Content Accessibility Guidelines WCAG 1.0 [WCAG10].
