(p) When a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required.
Forced logouts are common for securing web applications. If there has been no activity (e.g. submitting information to the database) after a preset amount
of time, the application will terminate that session, requiring the user to log in again.
An application's maximum idle time is often determined by the owner's security policy, but certain types of users must be considered when determining an
idle time value:
þ÷Those who suffer with dyslexia may have to re-read certain passages.
þ÷Those with certain visual disabilities may need more time to view the page.
þ÷Those who require assistive technology might not be able to navigate or enter data fast enough.
þ÷Those with limited physical mobility might not be able to navigate or enter data fast enough.
Additionally, a page or application should alert the user when the session is about to time out, and allow them the opportunity to request additional time.
Timed tests are common for on-line certification programs.
The time limit for an on-line test is usually calculated by the test's author to coincide with the curriculum or with the intended difficulty level. However,
certain types of users must be considered when determining an idle time value:
þ÷Those who suffer with dyslexia may have to re-read certain passages.
þ÷Those with certain visual disabilities may need more time to view the page.
þ÷Those who require assistive technology might not be able to navigate or enter data fast enough.
þ÷Those with limited physical mobility might not be able to navigate or enter data fast enough.
The time remaining must be displayed somewhere within the user agent (e.g. a countdown clock can be displayed on a web browser). However, it is understood
that assistive technology will probably have difficulty identifying such a countdown clock.
