Success Criteria

2.9.1 Adjustable Time Limits: The UA user interface does not include time limits or at least one of the following is true: (Level A)

  • Turn Off: Users are allowed to turn off the time limit before encountering it; or
  • Adjust: Users are 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: Users are warned before time expires and given at least 20 seconds to extend the time limit with a simple action (e.g. "press the space bar"), and users are 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 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.

    • The time limit is a required part of a real-time event and no alternative to the time limit is possible; or
