Time limits

  • Websites

Overview

Some people require more time than others to complete a task. For example, it generally takes people with physical disabilities or vision impairments more time to complete a web form than people with fast typing skills and perfect vision. Given this diversity among people, it’s difficult to predict how much time to allow for a given task. However, if security concerns or other factors require a time limit to be enforced, it’s important to be sure users are warned in advance before the time limit expires and offered an opportunity to extend their time.
