Add clarity or conformance level on accessibility A, AA, AAA for the for TV Apps

[Neha]

WCAG guidelines are clear for the website, and mobile apps. However, with the increase use of the OTT platform, the accessibility levels and guidelines are missing for TV apps. Eg:

1. Focused ring: what should be the color contrast for the TV apps for A, AA, AAA
2. Color contrast: for background color and text
3. Font-size: Minimum font-size
4. Navigation: How the navigation should be
5. Hints: How the hints should be, and position
6. Screenreaders: Usage of screenreaders

WCAG is technology-agnostic in its principles and criteria. Your points 1 and 2 are already covered with existing criteria. Points 3, 4, 5, 6 go outside of the scope of what WCAG in general mandates.

[GreggVan]

Correct. WCAG has always driven to be as agnostic as possible to the technologies used on the web.

However, this should not be confused with being technology-comprehensive.

What I mean by that is that:

• WCAG assumes things that are not always true when not talking about web content

• For example - it assumes there is a user agent.

  • so we eliminated 4.1.1 because we are assuming there is a browser that repairs all those things.
  • we assume there is always a keyboard or keyboard equivalent
  • we assume that there are AT that can be installed on the devices that house the browser (or that the user can choose a device that has the AT they need — and use that browser to access the content

• If you try to apply WCAG to non-web content and non-web software and mobile apps and to ICT in general

  • many of the provisions apply directly
    - others apply with simple words substitutions
    - still others apply awkwardly or do not quite work
  • but most importantly - there are all sorts of other things that WCAG does not even mention
    - all aspects of hardware
    - all aspects dealing with “closed functionality” products (hardware and software) that do not accept AT
    - how to provide access when there isn’t a browser or AT (users can choose which hardward to access the web mostly but cannot chose a different technology when they confront a kiosk or copy machine or thermostat or television or any other ICT.

WCAG2ICT is written specifically to raise these issues — but it only points them out and does not solve them or make WCAG comprehensive

So it is great for web content

it is (very) useful for non-web docs and software and mobile apps — but has to be adapted and does not cover all the areas / aspects.
