This video information is available as a Text Transcript with Description of Visuals below.

What is “Notifications and Feedback”?

Users need to know what is going on, and get appropriate feedback during interaction. For example, users need confirmation messages when actions are completed, such as when forms are submitted. Also, error messages must provide clear directions rather than confuse users.

Who depends on this feature?

What are the additional benefits?

What needs to happen for this to work?

Use clear and simple language to make error messages more understandable. For example, describe how to fix an error. When forms are submitted, provide a confirmation message. When a change is made on the screen, such as new content added, alert users to the change.

Web Accessibility Perspectives: Notifications and Feedback Web Accessibility Perspectives:
Notifications and Feedback
All the right gears can be put in motion. The hands can be at the exact place they need to be. The hands on a cuckoo clock reach twelve...
But if you don't get the response that you're expecting, you'll end up wondering if there's some sort of problem.
... but the cuckoo bird does not pop out of its door to signal the time.
It's the same on the Web.
Without clear notifications and feedback, people are quickly disorientated and confused.
A man completes and submits a form on a website to get a rather blank screen with no confirmation of his submission. He looks confused.
Especially error messages which are often complex and confusing.
Another man receives a technical error message from a website registration form. It reads: "Error ead#234532 invalid data".
Yet making them understandable is usually quite simple.
The error message changes to say: "Invalid format, required format is 'day/month/year'.
Making websites and apps predictable and understandable makes them accessible for people with cognitive and learning disabilities...
A woman is trying to log into the Wi-Fi of a cafe and receives a cryptic error message.
... and more usable for everyone.
Other people at the cafe also seem to be having this problem. Especially people with lower computer skills.
The error message changes to something more understandable. The woman at the cafe looks relieved.
Web accessibility: Essential for some, useful for all. The cuckoo bird pops out of the clock.
