Problemas y preguntas sobre accesibilidad web

En Accessibility Testing Newsletter de la University of Michigan he encontrado varios problemas y preguntas sobre accesibilidad web muy interesantes. Por ejemplo:

Web Content Accessibility Guideline (WCAG) Success Criteria 2.2.2 states 'For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential...' This criteria is tremendously helpful to assistive technology users, as well as to individuals with attention deficit disorder (ADD).

The news carousels now included on many sites are a type of 'moving, blinking, or scrolling information.' For example, here's a carousel from the U-M home page...

This carousel has the following features:

The picture only changes when the user selects a different picture.
All pictures can be selected using keyboard commands.
If the user navigates among the pictures using keyboard commands, the navigation follows a logical left-to-right order.
All pictures have descriptive text that can be read by screen readers.
Does this carousel meet WCAG Success Criteria 2.2.2?

WCAG Guideline 1.4.1. states that information conveyed via color needs to have at least one redundant visual means of conveying the information. This redundant strategy can be text, shape, or any other indicator that does not rely on color.

Planview has the following on its Authorized Work: Project View page:

Is the Planview use of colored circles compliant with Guideline 1.4.1? If not, what could be done to bring it into compliance?
