What’s a Display screen Reader?
You might have heard the time period “display reader” as you may have been shifting across the net. You would possibly even be utilizing a display reader at this second to run guide accessibility assessments on the experiences you’re constructing. A display reader is a kind of AT or assistive expertise.
A display reader converts digital textual content into synthesized speech or Braille output, generally seen with a Braille reader.
On this instance, I can be utilizing Mac VO. Mac VO (VoiceOver) is built-in to all Mac units; iOS, iPadOS, and macOS programs. Relying on the kind of gadget you’re operating macOS on, opening VO might differ. The Macbook Professional that’s operating VO I’m scripting this on doesn’t have the contact bar, so I can be utilizing the shortcut keys in keeping with the {hardware}.
Spinning Up VO on macOS
In case you are utilizing an up to date Macbook Professional, the keyboard in your machine will look one thing just like the picture under.
You’ll begin by holding down the cmd key after which urgent the Contact ID 3 times shortly.
In case you are on a MBP (MacBook Professional) with a TouchBar, you’ll use the shortcut cmd+fn+f5 to activate VO. In case you are utilizing a standard keyboard along with your desktop or laptop computer, the keys must be the identical or you’ll have to toggle VO on within the Accessibility settings.. As soon as VO is turned on, you can be greeted with this dialog together with a vocalized introduction to VO.
If you happen to click on the “Use VoiceOver” button you’re properly in your approach to utilizing VO to check your web sites and apps. One factor to remember is that VO is optimized to be used with Safari. That being stated, be certain if you find yourself operating your display reader check that Safari is the browser you’re utilizing. That goes for the iPhone and iPad as properly.
There are two major methods you should utilize VO from the beginning. The way in which I personally use it’s by navigating to a web site and utilizing a mixture of the tab, management, possibility, shift and arrow keys, I can navigate by way of the expertise effectively with these keys alone.
One other frequent approach to navigate the expertise is by utilizing the VoiceOver Rotor. The Rotor is a characteristic designed to navigate on to the place you wish to be within the expertise. Through the use of the Rotor, you eradicate having to traverse by way of the entire web site, consider it as a “Select Your Personal Journey”.
Modifier Keys
Modifier keys are the way in which you utilize the totally different options in VO. The default modifier key or VO is management + possibility however you’ll be able to change it to caps lock or select each choices to make use of interchangeably.
Utilizing the Rotor
With a view to use the Rotor it’s a must to use a mixture of your modifier key(s) and the letter “U”. For me, my modifier secret’s caps lock. I press caps lock + U and the Rotor spins up for me. As soon as the Rotor comes up I can navigate to any a part of the expertise that I need utilizing the left and proper arrows.
Navigating By Heading Degree
One other neat approach to navigate the expertise is by heading degree. If you happen to use the mix of your modifier keys + cmd + H you’ll be able to traverse the doc construction based mostly on heading ranges. You can even transfer again up the doc by urgent shift within the sequence like so, modifier keys + shift + cmd + H.

These will prohibit the shape from being submitted. The aria-required attribute explicitly tells the assistive tech that the sphere is required.
