1. Alex. Apple is bringing Alex, its natural-sounding voice on the Mac, to iOS. Alex will work with all of iOS’s spoken audio technologies (Siri excepted), including VoiceOver, Speak Selection, and another new Accessibility feature to iOS 8, Speak Screen (see below). In essence, Alex is a replacement for the robotic-sounding voice that controls VoiceOver, et al, in iOS today.
2. Speak Screen. With Speak Screen, a simple gesture will prompt the aforementioned Alex to read anything on screen, including queries asked of Siri. This feature will be a godsend to visually impaired users who may have issues reading what is on their iPhone and/or iPad. It should be noted that Speak Screen is fundamentally different from Speak Selection, which only reads aloud selected text. By contrast, Speak Screen will read aloud everything on the screen — text, button labels, etc.
3. Zoom. Apple has made some welcome tweaks to its Zoom functionality in iOS 8. The hallmark feature is users now have the ability to specify which part of the screen is zoomed in, as well as adjust the level of the zoom. In particular, it’s now possible to have the virtual keyboard on screen at normal size underneath a zoomed-in window. What this does is makes it easy to both type and see what you’re typing without having to battle the entirety of the user interface being zoomed in.
4. Grayscale. iOS in and of itself doesn’t have “themes” like so many third-party apps support — and even like OS X Yosemite’s new “dark mode”. iOS does, however, support a pseudo-theme by way of Invert Colors (white-on-black). In iOS 8, Apple is adding a second pseudo-theme to the system with Grayscale. With this option turned on, the entirety of iOS’s UI is turned, as the name would imply, gray. The addition of a Grayscale is notable because it gives those users who have issues with colorized display — or who simply view darker displays better — another way to alter the contrast of their device(s).
5. Guided Access. The big addition to Guided Access is that Apple is leveraging its own new-to-iOS-8 Touch ID developer API to enable users to be able to exit Guided Access using their scanned fingerprint. This is a noteworthy feature because it effectively guarantees that students (or test-takers or museum visitors) can’t leave Guided Access to access the Home screen or other parts of iOS.
As well, Apple has added a time limit feature to Guided Access, thereby allowing teachers, parents, and the like to specify the length of time Guided Access is to be used. Especially in special education classrooms, features such as Touch ID to exit and the timer can be extremely powerful in ensuring an uninterrupted learning experience, keeping students on task yet still set the expectation that a transition (i.e., “You can play games now”, for instance) will take place in X minutes. In terms of behavior modification, Guided Access’s new features are potentially game-changing, indispensable tools for educators.
6. Enhanced Braille Keyboard. iOS 8 adds support for 6-dot Braille input system-wide. This feature involves a dedicated Braille keyboard that will translate 6-dot chords into text.
7. “Made for iPhone” Hearing Aids. Apple in iOS 8 has improved its Made for iPhone Hearing Aids software so that now users who use hearing aids and have multiple devices now can easily switch between them. Moreover, if a hearing aid is paired with more than one device, users will now be able to pick which device they’d like to use.
8. Third Party Keyboard API. This topic (as well as QuickType) is worthy of its own standalone article, but the accessibility ramifications of iOS 8’s third party keyboard API are potentially huge for those with special needs.
