Operable 2.2 – Enough time

Provide users enough time to read and use content.

2.2.1 Timing Adjustable A For each time limit that is set by the content, at least one of the following is true.

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.

2.2.2 Pause, Stop, Hide A For moving, blinking, scrolling, or auto-updating information, all of the following are true. 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.
