legibility
<JohnRochford> Wayne admits to not being cool.

<AWK> I sent a note to Jon A about the session
Legibility and Readability
<JohnRochford> Wayne: Asked Gordon about about legibility levels.
[ Shawn put in a late comment this morning: "Keeping in mind the audience
and purpose of the document, I think we want to keep it a jargon-less as
possible. Maybe we don't even try to define terms -- we just explain the
concepts?"]
<JohnRochford> Wayne: Proposed 3 levels to Gordon, which he liked.
<JohnRochford> Wayne: font size, line spacing, etc., Gordon includes in
legibility
"things that are legible that you really can't read"
<JohnRochford> Wayne: There are things that are legible that people can't
read.
<JohnRochford> Wayne: Acuity limit = legible font that can be read
<JohnRochford> Wayne: Critical Print Size is second level, and is dependent
upon context, such as font and font size
<allanj> acuity limit = from eye exam under best conditions, limit of
persons acuity
<JohnRochford> Wayne: These levels exist for everybody
"see and recognize letters but functinoally not read too well"
<allanj> update paragraph in Requirements document:
http://w3c.github.io/low-vision-a11y-tf/requirements.html#functional-vision
<JohnRochford> Shawn: we should define terms "legibility" and "readability"
in doc:
http://w3c.github.io/low-vision-a11y-tf/requirements.html#functional-vision
current draft paragraph: [Editors' Note: The Task Force plans to change the
content of this paragraph.] Tasks may also impact a person’s functional
vision. For example, a person may be able to distinguish letters at a given
point size on a vision test where they are reading only one letter at a
time, but they cannot actually read blocks of text at that same point size.
This is the difference
between legibility and readability. Legibility is related to perceiving
text by distinguishing letters. Readability is related to reading and
comprehending textual information. Thus text could be somewhat legible to a
person, yet not functionally readable—with effort that user could
distinguish one letter from another, but could not effectively read
sentences.

<JohnRochford> Shawn: User need that started the conversation was the state
of a button
<JohnRochford> Is luminosity a sufficient affordance - does it fall under
"do not use color alone"?
<allanj>
http://w3c.github.io/low-vision-a11y-tf/requirements.html#not-relying-on-color
<JohnRochford> That was from Shawn
<JohnRochford> Shawn: Add an example of color indicating a state
proposal: add as an example under 3.1.3 Not Relying on Color "User Need -
Color: Color is not the only visual means of conveying information,
indicating an action, prompting a response, or distinguishing a visual
element."
<JohnRochford> Wayne: Yes, contrast is a function of color, but in common
usage, people don't think of contrast as being a color issue
<allanj> original 3.1.3 text: User Need - Color: Color is not the only
visual means of conveying information, indicating an action, prompting a
response, or distinguishing a visual element.
<JohnRochford> Shawn: Let's put the example in place and see if it works.
<JohnRochford> Wayne: Agrees
<scribe> *ACTION:* Shawn write out example for 3.1.3 that covers contrast
issue [recorded in http://www.w3.org/2016/03/16-lvtf-minutes.html#action03]
<trackbot> Created ACTION-42 - Write out example for 3.1.3 that covers
contrast issue [on Shawn Henry - due 2016-03-23].
review Sensory Characteristics
<allanj> close item 3
<JohnRochford> AWK: In communication with Jon A about this issue
Sensory Characteristics
https://www.w3.org/WAI/GL/low-vision-a11y-tf/wiki/LVTF_Open_Issues#Sensory_Characteristics
WCAG 1.3.3 Sensory Characteristics: Instructions provided for understanding
and operating content do not rely solely on sensory characteristics of
components such as shape, size, visual location, orientation..."
What are relevant issues particularly for low vision? Do we want to address
this with a user need? If so, ideas for wording?
<JohnRochford> Shawn: WCAG 1.3.3 jumped out at me
<JohnRochford> Shawn: Want to run it by people
<JohnRochford> Jim: Anybody object to closing this?
Information from Images - User Need? Information from Images - User need
<allanj> user need - low vision user need access to alt text at times
<JohnRochford> Wayne: This relates to issue of focus on screen-readers
<allanj> laura: users can perceive important information from images (alt
text, modifying image, etc.)
<JohnRochford> Laura: There are lot of low-vision people who don't (? -
Laura, please define)
<JohnRochford> Jim: What do we want to do: craft a user need?
<JohnRochford> Shawn: Are we going to say users can get the info from an
image?
<JohnRochford> Wayne: No, that's perceiving.
<JohnRochford> Laura: Agrees
<scribe> *ACTION:* Shawn draft images user need under 3.3 Perceiving for TF

<trackbot> Created ACTION-43 - Draft images user need under 3.3 perceiving

lvtf-ACTION-38: Review 3.1 contrast/color user needs
<allanj> close item 5
<JohnRochford> Wayne: Will carefully go through user needs next week
here are the user stories - use cases
https://www.w3.org/WAI/GL/low-vision-a11y-tf/wiki/User_stories_-_use_cases
there are are few open issues, which we have listed in
https://www.w3.org/WAI/GL/low-vision-a11y-tf/wiki/LVTF_Open_Issues
lvtf-Action-38 - contrast/color user needs
<JohnRochford> Wayne: Do we have any recommendations to WCAG for button
state issue?
<JohnRochford> Jeane: I think somebody from the group should comment on it.
<JohnRochford> AWK: I have been weighing in about this issue to the
conversation going on
<JohnRochford> AWK: Most of debate was about on-focus and on-hover
