Abstract:

Little has been written or done to advance the cause of web users with cognitive disabilities -- users who may actually require the use of graphics in order to make sense of a web site. For purposes of this document, we will use the term "Limited Textual Comprehension" to refer to anyone, disabled or not, who is unable to understand a web page -- and thus cannot access the information contained within in it -- due to the textual content of the page.
