Update from people working on functional user needs updates

Charles: I have 2 items

<CharlesHall> https://www.w3.org/TR/WCAG21/#audio-only-and-video-only-prerecorded

CH: 1.2.8 and 1.2.9
... I took the benefits from the Understanding doc
... I rephrased them using our language
... I then created a combined statement

<CharlesHall> Usage without the ability to listen due to: any human factor (like ear pain); or any technical factor (like poor signal); or contextual factor (due to quiet environment)

Janina: I wonder about quiet environment. You can put on headphones

Jeanne: Headphones aren't always an option. / For example, some people with tinnitus should not wear headphones.

<CharlesHall> https://www.w3.org/TR/WCAG21/#sensory-characteristics

<CharlesHall> Usage with limited color perception due to: human factors (like age); technical factors (like display quality); or contextual factors (like bright ambient light)

Jeanne: Is this really about functional needs rather than disability first needs? We decided about a year ago that we would do functional needs, knowing htat it is a controversial topic that may need to be revisited. '

Janina: not at this time

Charles: There are people that have trouble distinguidshing between colors but don't fall in the category of color deficiency.

jeanne: I would like to add the example of a disability here.

Charles: THere are studies of people over 65 who have trouble distinguishing gray colors or pastel colors, but have no trouble distinguishing the colors
... they may need to have a contrast range that is different than people with color deficiency.

Bruce: I think the way we are approaching it with WCAG 2 covers the examples given.

<bruce_bailey> yes, Andrew Sommers

Janina: Is there a measure that would help us?

Jeanne: Andy has said that there are technological improvements. He is working with Chuck and Cybele on Color Contrast. They said that they have a breakthrough that is exciting, but they aren't ready to report to the group on it.

Charles: It is called simultaneous contrast. It can be addressed in the Methods.

Bruce: That sounds good to me. It's a mechanic, that would be addressed in. I am more concerned about people who have too much color.

Janina: That is something we need to address to CSS. We need to get CSS onboard. We need better technological solutions.

<bruce_bailey> simultaneous contrast

Charles: The proximity of colors can be perceived differently, even if the contrast is the same

<bruce_bailey> charles gave example of buttons side-by-side impacting legibility

<Jan> I can scribe, Jeanne

<bruce_bailey> Example: a yellow text on red button next to a yellow button with red text -- both would be less legible

<Jan> Jeanne: We need more volunteers to work on functional needs

SC 1.2.2 Captions (Prerecorded), SC 1.2.4 Captions (Live), SC 1.2.6 Sign Language (Prerecorded)

User need(s) for captions (prerecorded and captions live)

scribe: Users cannot hear all or part of the audio component of movies and multimedia and need captions to fully understand the content.
... Users who need multisensory input need captions paired with audio to understand content.
... Users with situational, environmental barriers cannot hear all or part of the audio components in media and need captions to fully understand the content.
... Users learning a second language may use captions to support language acquisition.

User need(s) for sign language (prerecorded)

scribe: Users whose first language is sign language and cannot hear all or part of the audio component of movies and multimedia need sign language to fully understand the content.
... Users whose first language is sign language may have difficulty with the rate of captions and the structure of written language and need sign language to fully understand the content.

Jan: I'm not sure if we phrased it correctly.

Charles: I would suggest that "need captions" would be the Method, or solution

Jan: Different levels of hearing loss may have environmental problems related to their hearing loss. What may be audible in one environment may not be audible in another
... if you think of it as "a language" rather than a foreign language
... SHould I cross out the examples that are more Methods?

Charles: What I did was cross them out in the User Need section and move them into the Methods section of the Outline.
... It's relative -- if it is important to capture them for understanding, you should use them.

Jan: Right now it doesn't capture the user need of people with disabilities. People always assume we are talking about a sports bar.
... People with autism have difficulty processing environmental noise. I don't know if we need to state that.

Jeanne: I think you should include it. WHen people look at this work it will be helpful to have a more detailed breakdown of cognitive needs. Traditionally in standards work, we have had a detailed breakdown of sensory disability needs, but have kept congitive disability needs as one category, without a breakdown. The more we can breakdown cognitive needs and address them individually in

the functional needs, the better our work will be (in my opinion).

<janina> +1 to better specificity

Janina: I think "fully understand" would be very difficult to achieve -- particularly with artistic movies
... I think "effectively understand" would be an improvement and more achievable.
... Things are effective to a certain degree. They also require a certain amount of skill and that is not easy to achieve.
... people who learned sign language first may find captions very difficult to achieve
... deafness is socially isolating. That's a difference between sensory disabilities -- blind is not socially isolating.

<CharlesHall> sorry. I can’t commit to draft any more presently. busy ahead of TPAC.

<CharlesHall> i have to drop off the call now.

<johnkirkwood> have a good one!

Jeanne: Please volunteer for writing a functional need. It saves a lot of time when the hard work is done outside the meeting.

s/that would be addressed in. I am/that would be addressed in Methods. I am
