define vicusal indicators

    Jim: Lots of hours spent discussing the word "essential".
    ... Alistar says defining "visual indicators" is a good start.

    <Glenda> This is the note defining visual identifier - Examples
    of essential visual identifiers of user interface components
    may include (a border, edge, or icon), current value (such as
    non-text visual indication of aria-valuenow on a slider) and
    current state (such as selection indicator, focus indicator) or
    other essential visual indication (which do not rely on color
    alone).

    <Glenda> essential non-text visual identifiers of user
    interface components

    Glenda: If the non-text visual identifier is removed, nobody
    would know what the component is.

    <alastairc> Perhaps start with: Visual identifiers of user
    interface components are indicators that it is interactive,
    examples include...

    <Glenda> just drop the word “essential” becuase to be a visual
    identifier…is saying it is essential.

    <Glenda> non-text visual identifiers of user interface
    components

    Alastair: A user interface component could have a border around
    a pen symbol, for example.

    to indicate it's a button

    Glenda: contrast is in the complete control of the
    visual-identifier creator

    <Allanj_> Drop in a link please

    Alistair: Icons do not have to be interactive.

    <alastairc> My latest understanding doc can be previewed here:
    [14]https://alastairc.ac/tmp/graphics-contrast.html

      [14] https://alastairc.ac/tmp/graphics-contrast.html

    <alastairc> I've got some graphics in that version.

    Jim: Do we have to lay out such as on hover rather than just
    have a border?

    Glenda: Yes, it's not just a border.

    <laura> All Understanding docs linked from: Accepted WCAG 2.1
    SC: [15]https://www.w3.org/WAI/GL/wiki/Accepted_WCAG_2.1_SC

      [15] https://www.w3.org/WAI/GL/wiki/Accepted_WCAG_2.1_SC

    <alastairc> suggest adding a background? or is that what
    creates the edge?

    Glenda: Examples of visual indicators include a border, and an
    edge, and current state, such as a selection or a focus
    indicator.

    Alistair and Glenda: A background indicates an edge.

    Glenda: When we say "the edge", I think we should explain it in
    the understanding doc.
    ... By default, the natives are controlled by HTML, CSS, and
    the browser.
    ... Is the term "visual identifiers" strong enough?

    Alistair: Do we worry about an image with strong attributes on
    only one side?

    attributes, such as contrast

    Glenda: We handled that with a 3-pixel border on the bottom.

    <laura>
    [16]http://www.glendathegood.com/a11y/lvtf/textinputborder.html

      [16] http://www.glendathegood.com/a11y/lvtf/textinputborder.html

    <Allanj> If i create a custom radio buttio

    Glenda: I will add an example of good contrast only on one
    side, and poor contrast on the other 3 sides.

    Laura: What if the thick border was on the top?

    Glenda: Developers can do that, and it would technically pass,
    but it would have to go through usability with all humans .
    ... The SC does not require that the visual affordance exists.

      [17] http://www.glendathegood.com/a11y/lvtf/submitbuttonborder.html

    <Allanj> if i create a custom radio button... it is two
    graphics ckecked and unchecked... falls to alastair. The
    indicator that it has focus and was changed is glenda?

    Alistair: The contrast of the graphics would fall to me, yes.

    Glenda: Should we separate graphics that are image files from
    those created by HTML and CSS?

    Alistair: It's the concept, not the technology, which is good.

    <alastairc> [18]https://github.com/w3c/wcag21/issues/181

1.4.12 'essential' and exceptions

    <shawn> AlastairC will reply that these are addressed in the
    Understanding Doc

1.4.12 Push for 3:1 graphics contrast
[19]https://github.com/w3c/wcag21/issues/251

      [19] https://github.com/w3c/wcag21/issues/251

    <Allanj> We need to present the expert statements again from
    emails.

    Alistairc: Jared Smith says the research is old about the
    displays that we use.

    Alaistairc: Perhaps we put them in a Wiki?

    Alaistair: I think the graphics and explanations in the
    understanding will "go a long way".

    <Allanj> Will put on wiki . From gordon legge and agustus at
    smith kettlewell

    I apologize, Alastairc, for my misspellings of your name.
