## Leap Motion
The Leap Motion plugin lets you utilize your [Leap Motion](https://www.leapmotion.com/) device to control basic navigation of your presentation. The gestures currently supported are:
##### 1 hand + 1 finger
* Pointer — Point to anything on screen. Move your finger past the device to expand the pointer.
##### 1 hand + 2 or more fingers
* Left
* Right
* Up
* down
Navigate through your slides. See config options to invert movements.
##### 2 hands
* Up
Toggle the overview mode. Do it a second time to exit the overview.
#### Config Options
You can edit the following options:
* naturalSwipe: Defaults to true. Swipe as though you were touching a touch screen. Set to false to invert.
* pointerSize: Defaults to 15. The minimum height and width of the pointer.
* pointerColor: Defaults to #00aaff. The color of the pointer.
* pointerOpacity: Defaults to 0.75. The opacity of the pointer.
* gestureDelay: Defaults to 500. How long to delay between gestures in milliseconds.
Example configuration:
```js
Reveal.initialize({
// other options
leap: {
naturalSwipe : false, // Invert swipe gestures
pointerOpacity : 0.5, // Set pointer opacity to 0.5
pointerColor : '#d80000' // Red pointer
}
// Optional libraries used to extend on reveal.js
{ src: 'plugin/leap/leap.js', async: true }
```
## Installation
The **basic setup** is for authoring presentations only. The **full setup** gives you access to all reveal.js features as well as the development tasks needed to make changes to the source.
