Consistent Identification
Summary:
WCAG 3.2.4, "Consistent Identification," is about making sure that elements with the same function are identified consistently across a website. This guideline is vital for users with cognitive disabilities or those who rely on familiar patterns for navigation and understanding.
What:
This criterion requires that components with similar functionality are labeled and presented consistently within a set of web pages. It aims to create a consistent and predictable environment by ensuring that similar tools and elements are easily recognizable.
Why:
Consistency in identifying similar elements helps users, especially those with cognitive challenges or visual impairments, to quickly understand and use the website. It reduces the learning curve and potential confusion, making navigation more intuitive.
Examples and Scenarios:
- Search Functions: The search tool is labeled and looks the same on all pages.
- Contact Information: 'Contact Us' links or buttons are consistently identified across the site.
- Social Media Icons: Social media icons are uniformly presented on different pages.
How to Comply:
- Websites: Use the same labels and visual design for elements that perform the same function across different web pages.
- Mobile Apps: Ensure that icons, buttons, and other interactive elements are consistently identified throughout the app.
- Software Applications: Apply a uniform design and identification for similar functional elements within the software interface.
Exceptions:
- Different Contexts: In some cases, the function of an element might change based on the context, requiring different identification.
- Aesthetic Design: Creative or aesthetic choices in design might lead to variations in the identification of similar elements, as long as the overall functionality is clear.
