PEAT User Interface & Accessibility 5

Question 1

Which ARIA attribute is used to indicate that a disclosure button controls an expandable section?

Accepted Answer

aria-expanded

Answer

aria-expanded communicates to assistive technologies whether the controlled content is currently expanded (true) or collapsed (false).

Question 2

A PDF generated from a PEAT-assessed tool has untagged content. What is the primary accessibility issue?

Accepted Answer

Screen readers cannot determine reading order or semantics of the content

Answer

PDF tags define the document's semantic structure and reading order, which screen readers require to present content meaningfully.

Question 3

What distinguishes 'accessible' from 'usable' in the context of UI design?

Accepted Answer

Accessibility ensures people with disabilities can use a product; usability measures overall ease of use for all users

Answer

Accessibility specifically addresses barriers for users with disabilities, while usability evaluates the overall efficiency and satisfaction of the interface for all users.

Question 4

Which WCAG Success Criterion requires that error messages identify the specific field in error and describe the issue?

Accepted Answer

SC 3.3.1 Error Identification

Answer

SC 3.3.1 requires that input errors be identified in text, describing the item in error and the nature of the error to the user.

Question 5

What is the purpose of providing captions for prerecorded video content under WCAG?

Accepted Answer

To make spoken audio and significant sounds available to users who are deaf or hard of hearing

Answer

Captions (SC 1.2.2) present synchronized text of spoken dialogue and important sounds so deaf and hard-of-hearing users can access the audio content.
