<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.

<scribe> ACTION: Shawn and Wayne add to https://www.w3.org/WAI/GL/low-vision-a11y-tf/wiki/References#Functional_Vision legibility references [recorded in http://www.w3.org/2016/03/16-lvtf-minutes.html#action01]

<trackbot> Created ACTION-40 - And wayne add to https://www.w3.org/wai/gl/low-vision-a11y-tf/wiki/references#functional_vision legibility references [on Shawn Henry - due 2016-03-23].

<JohnRochford> Wayne: As experts on how to make things work on the web, we have the right to use operationalized terms

<JohnRochford> Wayne: as well as defining success criteria

<JohnRochford> Shawn, am I confusing Wayne with Jim?

<JohnRochford> I apologize

last comment: https://lists.w3.org/Archives/Public/public-low-vision-a11y-tf/2016Mar/0052.html

<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 discussion [recorded in http://www.w3.org/2016/03/16-lvtf-minutes.html#action04]

<trackbot> Created ACTION-43 - Draft images user need under 3.3 perceiving for tf discussion [on Shawn Henry - due 2016-03-23].

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

<allanj> scribe: jimA
