Re: Possible draft of 3.2.7

Hi Gregg,

The key thing we haven’t worked out is a common way of understanding what a ‘visible indicator’ is.

This doc includes a mix of the original examples and things I found from a search for interfaces using on-hover interactions:
https://docs.google.com/document/d/1Cn9SvuOiu_m-phcyK5IdtipNzyoM2pkcCHbnWfcqsNc/edit#

Put aside pass/fail, what would constitute a visible indicator in each case, and does it have one?

The only one that all 12 people who answered the survey<https://www.w3.org/2002/09/wbs/35422/wcag22-visible-controls/results#xq19> agreed was SquareSpace’s (old?) interface where it just looks like a rendered page, but hovering over things provides edit-controls.

Part of the problem is what people bring to it affects the results. For example, hovering over a video thumbnail is a very common way of providing controls on-hover. Is the video itself an indicator? Is that enough?

Is the context of a menu enough to signify drop-down options? What if some menu items have drop-downs and some don’t? Are we trying to require an icon (or equivalent) for every menu item which has drop-downs?

Is the context of a photo-editing interface context enough that you would assume there are on-hover interactions?

Without creating a catalogue of examples (which I don’t think would scale or internationalise), we don’t seem to be able to come to a reliable answer.

Subject: Possible draft of 3.2.7
This is a rough first draft of an alternative for Success Criterion 3.2.7

Please anyone send me comments on how to improve this — or problems I missed.

Thanks

Gregg



Success Criterion 3.2.7 Controls Visible as Controls (Level AA): When user interface components are invisible or not visually indicated as controls until hover or focus, provide a visible indicator that the components are available and are controls, except when:
•       The same functionality is available through a component on the same page, or on a different step in a multi-step process, without requiring pointer hover or keyboard focus to make it visible as a control;
•       The component provides keyboard-only functionality;
•       A mechanism is available to make the components persistently visible as a control;
•       A mechanism makes controls visible as controls whenever a pointer is moved within or over the page, page is clicked anywhere, or keyboard is used – and stays visible for at least 3 seconds after movement or keyboard operation stops
•       Hiding the visibility of the control as a control is essential to the purpose of the page.

Examples of problems that fail

•      Controls are hidden unless the person points directly to the control

•      Page where links are not visible until the person tabs to them

Examples that pass

•      Movie where all controls are hidden but show up as soon as mouse is moved, person touches the screen anywhere, or the keyboard is used.

•      Page where links are hidden but show up as soon as mouse or keyboard are used within or over the page.
