PRINCIPLE 1: PERCEIVABLE Flashcards
Information and user interface components must be presentable to users in ways they can perceive.
GUIDELINE 1.1
TEXT ALTERNATIVES
Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language.
SUCCESS CRITERION 1.1.1
NON-TEXT CONTENT (A)
All non-text content that is presented to the user has a text alternative that serves the equivalent purpose.
GUIDELINE 1.2
TIME-BASED MEDIA
Provide alternatives for time-based media
GUIDELINE 1.3
ADAPTABLE
Create content that can be presented in different ways (for example simpler layout) without losing information or structure.
SUCCESS CRITERION 1.3.1
INFO AND RELATIONSHIPS (A)
Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text.
SUCCESS CRITERION 1.3.2
MEANINGFUL SEQUENCE (A) When the sequence in which content is presented affects its meaning, a correct reading sequence can be programmatically determined.
SUCCESS CRITERION 1.3.3
SENSORY CHARACTERISTICS (A) Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, color, size, visual location, orientation, or sound.
SUCCESS CRITERION 1.3.4
ORIENTATION (AA)
Content does not restrict its view and operation to a single display orientation, such as portrait or landscape, unless a specific display orientation is essential.
SUCCESS CRITERION 1.3.5
IDENTIFY INPUT PURPOSE (AA)
The purpose of each input field collecting information about the user can be programmatically determined when:
- The input field serves a purpose identified in the Input Purposes for User Interface Components section; and
- The content is implemented using technologies with support for identifying the expected meaning for form input data.
