Off Survey

I have some edits that I consider important:
1) The writers of the functional limits sections should write the
abbreviated versions. It won't be hard to cut them down to 1 or 2
paragraphs.
2) We should note that the visual impairments we explore are the ones we
deem important to the web.
2. One category of visual impairment should Multi-Impairment.
Multi-impairments need more complex access than impairments occurring
singularly.
3. There are actually three levels of text recognition: visible: The
smallest line you can read on the eye chart. Legible: text that enable
reading streams of words as rapidly as possible and with minimal error.
Readable: text that enables comprehension of large bodies of text,
including book length documents.

The distinction between visible and legible is significant and cannot be
lost. Text in the smallest line you can read in the eye chart is not
legible to you. You will read words slowly and make a lot of mistakes.
Visibility and legibility are matters of perception (P in WCAG 2). Items
1.3 and 1.4 assist legibility.

Readability is about "operating" bodies of text. You can skim text for the
gist. You can read carefully for the deep meaning. Even though reading is
passive it is still an operation. It is the point where multi-impairment
come into play. If we decide to optimize to the smallest legible font size,
we are forced to have a bright interface. This may not be conducive to the
long reading sessions necessary for comprehension of the assigned block of
text.
