Feedback about Errors is not timely

Short Description

A user is not immediately made aware of an error

Long Description

  • Frequently, alerts about errors, particularly when completing forms, will be made visible to sighted users at the moment the error is made.
  • It is important to know about the error at the time when it is made, because it is easier to find the problem and fix it when a user is at the related form field.
  • When an alert appears in a part of the screen that is distant from the error, a screen magnifier user might not be able to see it, because they can only focus on a limited part of the screen at a time.
  • It is important to make the screen reader software aware of an alert so it will read it out loud to the user.
