# accessibilityBrailleMapRenderRegion

A region of the UI that the system converts into a braille map and displays on the braille display.

## Declaration

```swift
optional var accessibilityBrailleMapRenderRegion: CGRect { get set }
```

## Discussion

Discussion When the accessibility element that implements this property has focus, the system uses this value to update the braille display automatically. Set this value to specify a region of the accessibility element — relative to its bounds — to display on the braille display. VoiceOver snapshots the region of the accessibility element that you specify, converts the data to a braille map, and renders the braille map to the braille display.
