Re: Examples of when people need text alternatives for images

  Hello Shawn,
Your proposal seems good to me.
As far as the second bullet is concerned, what about also talking about 
users who are deaf blind (they are mentionned in Understanding WCAG 2.0 
and often forgotten elsewhere),b ut they can only rely on braille 
display (no access to synthetic speech).
This second bullet could be:
- Users who are blind and deaf blind use a dynamic braille display to 
get information from the web page.
In the next bullet, I wonder if users with cognitive disabilities only 
use screen readers? I think there are possibilities to have software 
reading text that is selected with the mouse or copied and pasted in the 
clipboard.
So I suggest for this bullet:
- Users who have a cognitive impairment that makes it difficult
or impossible to read, and have text  read by speech synthesis when they 
select it with the mouse or copy it to the clipboard.
Best
Sylvie
