UI Accessibility Plugin  Version 1.0.0
Make your UI accessible for visually impaired users
Navigation on the Play Grid

How It Works

This page explains to seeing developers how blind users can navigate your app and your menus in accessibility mode.
The navigation was modeled as closely to the accessibility functions on iOS (VoiceOver) and Android (TalkBack) as possible.

In addition to the navigation input listed on this page the plugin handles Magic Gestures for action such as Back and Pause.

Explore By Touch

Users can simply swipe over the screen and the accessibility manager will read out what UI element is under the finger. Explore By Touch is a fast way of finding buttons if the user already has a rough idea where they are located. Don't be tricked into thinking that visually impaired gamers don't remember where buttons are located.

Explore By Touch is meant for iOS and Android and is disabled on Window by default.
You can enable it manually (for testing or if you want to go crazy) in the Accessibility Manager settings.

Swipes

Swiping left and right will jump from one UI element to the next. On Windows, the up and down arrow keys are mapped to this feature (and these keys are customizable). Swiping up and down will jump to the next UI group, if there are any (= group of UI elements, see Plugin Basics).

Containers can also opt to use 3D grid navigation instead. This is useful for grid based puzzle games (for example Match 3 games). See the HowTo section for more info.

Cyclic Menus

By default, all screens are treated as non-cyclic menus, meaning, when the bottom of the screen is reached, swiping again will not change the focus and a notification sound will play, indicating that the end of the screen was reached. This can be changed in the Settings using the "Cyclic Menus" check box. If this is turned on, then swiping right at the bottom of the screen will jump back up to the first element.
Do not turn this on without reason. The default is off, because this is how VoiceOver handles the screen borders, and the feedback from blind beta testers has been that this is the preferred way of handling it, too.

Read From Top

Swiping down from the top of the screen with two fingers will trigger Read From Top. This makes the accessibility manager read out all accessible UI elements on the screen in sequential order. It is very useful to get an overview over the screen, and to make sure no buttons etc are missed.

Read From Top is available on iOS and Android only.

Buttons and Toggles

Buttons and Toggles are activated with a double tap, after they have been selected. A single tap on a button, toggle or any other UI element will only select it (via Explore By Touch, but not trigger it. On Windows, the Enter will activate the element. This key is customizable.

Sliders

After a slider is selected, users can double tap it to change the value (Enter on Windows). Swiping up and down will change the value up or down (you can adjust by how much). On Windows you can use the up and down arrow keys to change the value. Double tapping (or Enter) again will end the interaction and let the user continue navigating as usual.

Scroll Lists

Scroll lists and scroll views can be navigated using regular left and right swipes (Up and Down Arrow Keys on Windows).
The plugin will traverse all elements inside the scroll view as normal, and automatically move the viewport so that the current element is visible.
This works for two dimensional scroll views as well. Take a look at the Navigation Example scene to see this in action with a 2D scrollable map.

Selection Frame

A high contrast black frame (you can change the color) will be laid around the currently selected UI element.
This helps user that are not completely blind determine what is currently selected, and it tremendously helps developers see what's going on.
This is based on a similar feature from the screen readers on iOS and Android.
