Perceivable - Ensuring Information is Presentable

A11y.Cafe ~

Perceivable, focuses on ensuring that information and user interface components are presentable to users in ways they can understand by using sight, sound or other assitive technologies. This principle encompasses guidelines related to providing text alternatives for non-text content, ensuring sufficient color contrast, providing captions and alternatives for multimedia, and making content adaptable or available to assistive technologies.

Guidelines

  1. Text Alternatives: Provide text alternatives for any non-text content, such as images, icons, and multimedia, so that it can be changed into other forms that people need, such as large print, braille, speech, symbols, or simpler language.

  2. Time-based Media: Provide alternatives for time-based media, such as captions for audio and audio descriptions for video.

  3. Adaptable: Create content that can be presented in different ways without losing information or structure, so that it can be adapted to meet the needs of different users, including those with disabilities.

  4. Distinguishable: Make it easier for users to see and hear content, including separating foreground from background, ensuring sufficient color contrast, and providing alternatives for audio and visual information.
