Foreword 前言

• the requirements related to Real-Time Text (RTT) in clause 6.2 have been revised and extended; 
• $$$$quad\quad the WCAG 2.1 AAA Success Criteria that were previously in an Annex D are now included in clause 9.5; 
• a new Annex D, “Further resources for cognitive accessibility”, has been added; 
• a new Annex E “Guidance for users of the present document” has been added. 
• a new Annex F “change history” has been added. 

Modal verbs terminology 

Introduction 

• Clauses 0 to 3 include background information, the scope of the standard, and links to other standards, definitions and explanations of abbreviations. 
• $$$$quad\quad Clause 4 contains functional performance statements that explain the functionality that is needed to enable users with different abilities to locate, identify and operate functions in technology. The user needs underlying the functional performance statements are the basis for the requirements in subsequent clauses. 
• $$$$quad\quad Clauses 5 to 13 provide specific testable criteria for accessible ICT, related to technical requirements for different kinds of ICT, starting with generic requirements in clause 5. 
• $$$$quad\quad Clause 14 is about conformance. All clauses except those in clause 12, related to documentation and support services, are self-scoping. This means they are introduced with the phrase ‘Where ICT <pre-condition>’. Conformance is achieved when the pre-condition is true and the corresponding test (in Annex C) is passed. When the pre-condition is false the requirement is not applicable. 
• Annex A has two tables with requirements related to Directive 2016/2102 on the accessibility of the websites and mobile applications of public sector bodies [i.28]. The first table applies to web pages and documents and the second applies to mobile applications. The minimum requirements are collected from clauses 9,10 and 11 and some requirements from clauses 5, 6, 7 and 12 that are relevant to fulfill the Directive. 
• Annex B contains a table showing which of the requirements set out in clauses 5 to 13 related to different types of ICT support the user needs as expressed in the functional performance statements of clause 4. 
• Annex C is a normative annex that sets out the means necessary to determine conformance with the individual requirements. It does not provide a testing methodology. 
• Annex D points to additional resources related to improving accessibility for users with limited cognitive, language and learning abilities. 
• Annex E provides an overview and simple explanation of the structure of the present document, including an explanation of how it can be used. 
• Annex F provides a change history table.

11.2.2.1 Timing adjustable

• Turn off: The user is allowed to turn off the time limit before encountering it; or
• Adjust: The user is allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or
• Extend: The user is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (for example, “press the space bar”), and the user is allowed to extend the time limit at least ten times; or
• Real-time Exception: The time limit is a required part of a real-time event (for example, an auction), and no alternative to the time limit is possible; or
• Essential Exception: The time limit is essential and extending it would invalidate the activity; or
• 20 Hour Exception: The time limit is longer than 20 hours.

11.2.2.2 Pause, stop, hide

• Moving, blinking, scrolling: For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential; and
• Auto-updating: For any auto-updating information that (1) starts automatically and (2) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.
  NOTE 1: For requirements related to flickering or flashing content, refer to WCAG 2.1 Guideline 2.3.
  NOTE 2: This success criteria is applicable to all content in the software (whether or not there is an alternate accessible mode of operation of the software) since any part of a software that does not meet this success criterion can interfere with a user’s ability to use the whole software (including a user interface element that enables the user to activate the alternate accessible mode of operation).
  NOTE 3: Content that is updated periodically by software or that is streamed to the user agent is not required to preserve or present information that is generated or received between the initiation of the pause and resuming presentation, as this may not be technically possible, and in many situations could be misleading to do so.
  NOTE 4: An animation that occurs as part of a preload phase or similar situation can be considered essential if interaction cannot occur during that phase for all users and if not indicating progress could confuse users or cause them to think that content was frozen or broken.
  NOTE 5: This is to be applied to all content. Any content, whether informative or decorative, that is updated automatically, blinks, or moves may create an accessibility barrier.
