This course will cover the all of the iOS accessibility features up to iOS 6 for both the iPhone and iPad. The course with go in depth into 3 key accessibility features; VoiceOver, AssistiveTouch and GuidedAccess
Vision features: The first dilemma that you have to overcome when it comes to the iPad is, the iPad has a few buttons on the outside, but generally speaking, the primary interface is a large 10-inch touchscreen. If you are completely blind or partially blind, a touchscreen may or may not be an adequate interface for you.
VoiceOver is technology that is actually used on the desktop as well, and it’s been brought over to the iPad. The first problem that has to be conquered is that the iPad doesn’t have a cursor, so the iPad doesn’t know where you are onscreen.
VoiceOver: You can think of VoiceOver as a voice narration for where you are onscreen. It’s voice navigation when it comes to the home screen. It can also be an aid to information. For example, when you have email and you’re reading email, it can also read the email back to you.
It’s an audio cursor, and it’s constantly giving you feedback. These are called screen readers, and the way that generally screen readers work is they start in the upper left-hand corner, and they go to the lower right- hand corner. If you’re on, for example, the home screen, and you’ve got two dozen items on it, then navigating from the upper left hand corner to the right hand corner is not a problem. You tap anywhere onscreen, and it moves the cursor from one item to the next.
The dilemma exists when you are on a webpage, and now a webpage, when you think about letters or words or hyperlinks or paragraphs, there may be literally thousands of items on a page. And so starting in the upper left hand corner and going letter by letter all the way down to the lower right hand corner of a screen becomes very tedious and not very productive for the user.
There’s a key concept here, and that is the concept of the rotor. Let me step back, and let me define the rotor first. Then I’m going to tell you the context of this.
The rotor allows you to change the settings of VoiceOver what it navigates from. For example, Setting One could be letter by letter. Setting Two could be word by word. Setting Three could be sentence by sentence. Setting Four could be link by link.
As you change, and the way the rotor works is you twist your hand or you use two fingers, and you rotate two fingers, and that then changes the setting. Let’s say you’re in a webpage, and you are starting in the upper left hand corner and you’re going letter by letter, and that’s just too tedious.
You use the rotor to then change word by word or sentence by sentence or paragraph by paragraph or link by link. Now, you can go navigate down to where you want, and find the information that you want. Then you can change the rotor back to word by word, and it can read you back the content that you want. The rotor allows you to change the VoiceOver settings.
There’s a couple key concepts about the rotor. First one is the rotor allows you to change the VoiceOver settings without having to go back into the settings program and change it. The second thing that VoiceOver in general does, in combination with the rotor, is on a per program basis you can decide what e
