Checkpoint 1.19 - Java

At times applications may require input from a user. In the absence of user input, the application may submit a default value for processing. Where this is done using a time limit, some users may not be able to react quickly enough to enter their preferred data, with the possibility that the assistive technology is causing some time delay. To facilitate better use of this type of function, an application should be constructed so that a user can increase the time limits to enter information.

Requirement

The user is able to increase any time limits within the application.

Recommendation

The following points will contribute to making the application more accessible in terms of time limits:

• Users should be able to cause timed instructions to persist.
• Users should be notified when a time-out is going to occur and give them the option of requesting more time to respond.
• Important messages should not be displayed using time limits and should persist until the user closes the messages.

Checking Tool

Go to any sections of the application that require user response and delay the response to check for time-outs and their accessibility functionality. Check for any time-outs of informational messages to the user.
