Timed Responses

Accessibility Standards Checklist

Requirement

Alert the user when a timed response is used and give sufficient time to indicate that more time is required.

Reason

Some users have difficulty reading or responding to information if it is displayed briefly or requires quick response time. Some Web pages are designed to time-out for security reasons. Some response delays may also be caused by the use of assistive technology used to read the page. The user should be notified that the process is about to time out and be given the opportunity to indicate if additional time is required.

Examples

Timed Response

If the time-out occurs on the server, the server should send a message to the user indicating the process will time out. Otherwise, use JavaScript to generate a pop-up or dialog to inform the user of the time-out and allow them to request additional time. The user needs to have control over the timing of content changes. The message would appear similar to that below:

The time allotted has elapsed. By clicking on the "I need more time " button below you will have 10 more minutes to complete the application.
