Strategies for minimizing difficulties arising from timed responses and time limited actions.

• Allow users to proceed at their own pace.
• If product requires a quick response (a reaction time of < 5 seconds or the release of a key in < 2 seconds) allow the user to adjust the time interval or provide a non time dependent alternative.
• Ensure that time-outs are long enough to accommodate users who may need extra time.
• Set all time limitations to very high values.
• Warn the user when time is running out and allow them to secure extended time.
• Provide the ability to cancel an input, undo an operation or otherwise "back up."
