New in iOS 8: Greyscale Mode

iOS 8 includes a new greyscale mode that could benefit people with visual impairments. The new mode is included in addition to inverse color which was previously available. The new option will reduce the bright colors and possibly reduce glare to make the screen easier to see. Greyscale and inverse color can be enabled simultaneously for further visual changes. Even for people without visual impairments greyscale maybe made the screen slightly easier to view outdoors.

To enable greyscale navigate to Settings > General > Accessibility > Greyscale. Please note that the above screenshot is an altered colored screenshot.

New in iOS 8: Built-in Braille Keyboard for Six-Dot Input

iOS 8 includes enhancements to VoiceOver, the built-in gesture based screen reader for people with visual impairments. One of the improvements is a new built-in Braille Keyboard for Six-Dot input. The new feature is similar to the BrailleTouch app released a few years ago with one major difference; the built-in option can be used to enter text into any app directly. The option can be enabled in the VoiceOver rotor. The Braille keyboard will offer VoiceOver users who are familiar with Braille an alternative, and possibly much faster text entry method. iOS 8 will also offers third-party keyboards such as Fleksy which could also offer significantly faster text input for VoiceOver users.

Once you turn the Braille keyboard on six positions will appear on screen representing the six Braille dots. When the device is held with the screen perpendicular to the floor it automatically enters screen away mode. When using this mode the user faces the screen away allowing three fingers from each hand to contact the screen. As the user begins to type the six virtual dots automatically reposition themselves to compensate for changes in your grip. The dots can also be recalibrated by holding down the three right hand fingers and then the three left hand fingers immediately after. This positions the dots directly under your fingers.

When the device is set on the table or another flat surface the Braille keyboard enters tabletop mode. This mode would seem to be ideal for an iPad can can also be used on smaller devices. It does take some care to ensure that the keyboard does not switch between tabletop and screen away mode accidentally. In both modes typing did seem difficult on the small screen, but some practice seemed to improve typing speed. This new option allows typing with contracted or uncontracted Braille. When typing a swipe right adds a space and a swipe left deletes the last character typed. This new method of typing is very sensitive a will likely require practice before mastering. If you use this feature frequently, it maybe helpful to purchase a case that boarders the screen to avoid trying to type on the bezel.

To enable the Braille keyboard go to Settings > General > Accessibility > VoiceOver > Rotor > Braille Screen Input. Then, when VoiceOver is enabled, rotate the rotor until Braille screen input is selected. It exciting to see all the new third-party keyboard options for iOS 8, but for VoiceOver users, Apple's own Braille keyboard maybe the most exciting of all.

New in iOS 8: Start Text-To-Speech Easily with Speak Screen

iOS 8 includes some new accessibility features and many improvements to existing features. One of the new features is called Speak Screen which allows users to quickly have text on the screen spoken aloud using text-to-speech. Speak Screen is included in addition to Speak Selection which allows users to highlight text and press speak to have content read aloud.

Unlike Speak Selection, which requires text to be highlighted first, before reading the text aloud,  Speak Screen does not require users to highlight the text they wish to have spoken. Especially for longer articles or emails, this highlighting process could be time consuming and frustrating.

Speak Screen solves the problem by speaking all text on the screen with a simple two-finger swipe down from the top of the screen. After swiping down with two fingers, text starts to be read aloud with text-to-speech, and the Speak Screen menu appears on top of your current app. This menu allows you to stop and start speech, adjust the text-to-speech speaking rate, and navigate through the text being spoken.  Instead of having to re-highlight text if you want to hear a paragraph again, Speak Screen offers simple navigation buttons. The menu can also be hidden to allow full view of the screen and accessed again through a small floating button. Just like Speak Selection, Speak Screen has the option to highlight text as it is spoken, making it easier for sighted readers to follow the text as it is being spoken.

Just like all of the accessibility features in iOS 8, Speak Screen can use the Alex text-to-speech voice which many users prefer. While Alex is a very high quality text-to-speech voice beware, it takes up almost one gigabyte of storage. Speak Screen can also be activated through Siri by saying "speak the screen." To enable Speak Screen on a device with iOS 8 go to Settings > General > Accessibility > Speech and then toggle on Speak Screen. Speak Screen is only available for devices running iOS 8 or higher.

New in iOS 8: Vastly Improved Zoom

In previous versions of iOS, zoom was only  a simple full screen magnification. With iOS 8, Apple has vastly improved zoom with partial screen window zoom, filters, and smarter magnification options. Zoom is a vital feature for people with low vision and its new features in iOS 8 makes it even more useful.

One of the most noticeable enhancements is the ability to magnify certain areas of the screen while leaving the rest of the screen unmagnified. As opposed to full screen zoom, the zoom lens allows for more easy navigation while still allowing certain important areas to be magnified. Users can change the size of the magnified area and pan around the screen in order to magnify different areas. An option is available to add a zoom control to the screen which acts like a virtual joystick for controlling which areas of the screen are magnified.Within the magnified area, users can apply filters to make viewing easier.  The filters available are inverse colors, greyscale, low light, and greyscale inverse.

As pictured above, iOS 8 allows users to choose not to magnify the keyboard. This can make typing on software keyboards much easier while still allowing the text being entered to be enlarged. When the keyboard is magnified some keys are cut off requiring panning to type, iOS 8 eliminates this problem. Zoom also includes the ability to follow the VoiceOver cursor focus. Meaning when the VoiceOver cursor is focused on an app or button, that app or button will be enlarged in the zoom window.

These new zoom options are just one of many exciting accessibility enhancements included in iOS 8. The improved zoom will benefit many users with visual impairments and is a huge improvement over zoom in iOS 7. To enable zoom go to Settings > General > Accessibility > Zoom.

What a Larger Screen iPhone Means for Accessibility

The general consensus is that Apple will introduce new iPhones with larger screens in a few days. With many people with disabilities using Apple's flagship device for their accessibility needs a change can have a large impact on users. From a software prospective iOS 8 will offer many accessibility improvements, but hardware is also an important aspect of accessibility. The larger screen will certainly benefit some users with special needs, but may also cause problems for others.

Users with low vision may benefit the most from the larger viewing area. On current iPhones, with large text enabled, only a small amount of text is able to fit on screen. A larger screen will allow more text to fit on screen requiring less scrolling for users who prefer or require large text. The large screen will also give VoiceOver users more space to use three or four finger gestures.

On the other hand a larger screen iPhone may pose a challenge. Users with physical challenges may have a difficult time reaching all the controls. Also users who prefer using their phone in one hand and users who can only use one hand to operate their phone may find it difficult access all areas of the screen. It is possible that Apple will come up with a software solution to these possible challenges, making one handed use a breeze. 

When Apple introduced the iPhone 5 it claimed that the larger screen was a perfect size for one handed, use so it will be interesting to see how the next iPhone is marketed.

People who use Apple devices as assistive devices should be excited about the company's upcoming announcement. Regardless of any hardware changes Apple's iOS 8 includes unmatched accessibility features for people with a variety of needs. The potentially larger screen size will likely benefit most users. The benefits and trade-offs of larger screen phones has been explored with Android phones for years, and hopefully Apple has been able to iron out any lasting challenges. Aside from the form factor, Apple may introduce new software or hardware features that impact people with disabilities at their event. Stay tuned for information about how Apple's announcements impact accessibility.
