The WCAG Explained

Summary:
WCAG 3.3.5, "Help," centers on providing users with necessary support while filling out forms or entering data. This guideline is particularly beneficial for users with cognitive disabilities, learning disabilities, or those unfamiliar with specific data requirements, ensuring they can complete tasks without unnecessary hurdles.

What:
This AAA-level criterion requires that context-sensitive help be available for users, especially for complex or crucial forms and data entry tasks.

Why:
Providing help and support tools can significantly ease the process of filling out forms or entering data, reducing the likelihood of errors and the frustration associated with complex or unfamiliar tasks.

Examples and Scenarios:

1. Complex Forms: Incorporating a 'Help' button with detailed instructions or FAQs for complicated forms like tax submissions.
2. Registration Processes: Offering live chat support or tooltip explanations for each field during account creation.
3. Financial Applications: Providing step-by-step guides or video tutorials for entering financial data.

How to Comply:

• Websites: Implement various forms of help, such as tooltips, instructional text, FAQs, or live support options, particularly for complex input areas.
• Mobile Apps: Offer in-app assistance, like question marks next to input fields that users can tap for more information.
• Software Applications: Integrate context-sensitive help features within the software's interface.

Exceptions:

• Basic or Common Tasks: For standard or straightforward forms where additional help may not be necessary.
• Self-Explanatory Interfaces: If the interface is designed to be intuitive and self-explanatory, extensive help features might be redundant.
