# VoiceOver
VoiceOver is an Accessibility feature available on Apple platforms. It provides
an interface between your app and your blind or low-vision users. In short, it's
a screen reader.
## Overview
[Activating VoiceOver](#Activate-VoiceOver) fundamentally changes the touch
interface of an iOS device, so when you activate it, you need to know these
basic commands to navigate:
- VoiceOver focuses an item on the screen and speaks it to the user.
- To navigate between items, you can either flick left/right to go to the
previous/next item, or you can drag your finger around the screen.
- Double tapping anywhere on the screen activates the item (no need to double
tap exactly on the item on the screen).
- Items have a label (describing the item) and can have among others:
- traits (describing the item: a header, a button, selection state, etc.);
- a hint (describing how to interact with the item).
The following video is a great summary. The content is succinct, high quality
and up-to-date, even though the video quality is low and the demo is on an
iPhone 3GS.

## Activate VoiceOver
Go to `Settings > General > Accessibility > VoiceOver` and toggle the top
switch.
Alternatively, if you are activating/deactivating VoiceOver often, I'd advise
to set it as the Accessibility Shortcut. When enabled, a triple tap on the Home
button will toggle VoiceOver ON and OFF from anywhere.
```
Settings > General > Accessibility > Accessibility Shortcut
```
