Apple's voice activated features have received some new features as part of iOS 8. Siri is a virtual voice activated personal assistant that can answer your questions, call your friends, check the weather, and much more.  Now it can  be activated hands free by saying, "Hey, Siri." Previously, users would have to press and hold the home button to activate Siri.

The new feature will allow people with physical disabilities to easily activate Siri. The hands-free activation feature does have one major caveat: the device must be plugged in and charging. Users who need or want to access this feature on- the- go can purchase a battery case to utilize this feature. It is possible that future iOS devices will not require a power source to use the "Hey, Siri" feature.

In addition, when dictating a question to Siri or dictating text into an app the recognized words appear almost instantly after being spoken. To use dictation bring up the keyboard and then press the microphone icon next to the space key. With words appearing as you speak it is easier to identify mistakes which makes the dictation process faster. Dictation can be a useful feature for people who struggle with spelling and people who have difficulty using a keyboard. These features are available for devices running iOS 8.

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.

Guided Access is one of the many iOS features being enhanced in iOS 8. Guided Access is used to keep a someone on a single app using  a password. For example, if you want your child to read a book and not watch a video you can lock them into the reading app, eliminating the ability to navigate to other apps. With Guided Access enabled, a child or student will need a passcode in order to enter another app. To learn more about Guided Access click here.

One of the enhancement allows users to end a Guided Access session with their finger print using Touch ID. Similar to how third-party developers can implement Touch ID authentication, Guided Access will also take advantage of finger print reading technology. Instead of entering a passcode, users with a Touch ID enabled device will be able to end the session simply by placing their finger on the Touch ID sensor. This feature will simplify the processes of ending Guided Access and potentially eliminate the frustration resulting in forgotten passcodes.

The other enhancement allows students and parents to set a time limit. After the time expires the app will not respond until the correct passcode or finger print is entered. Periodically a small message appears showing how much time is remaining. This feature could be perfect for test taking by ensuring students stop answering questions after the allotted time expires, or for setting a time limit for playing games- when the time limit is reached, the app will not respond.

To enable Guided Access navigate to Settings > General > Accessibility > Guided Access.

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.

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.

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.
