• Put an End to Boring Presentations with Reveal.js

Getting Started

1. Download and install the package in the presentation project: npm i -S reveal-leap-motion
2. Add the plugin to the dependencies in the presentation, as below:

Reveal.initialize({
    // ...
    dependencies: [
        // ...
        { src: 'node_modules/reveal-leap-motion/reveal-leap-motion.min.js', async: true }
    ]
});

Config Options

You can edit the following options:

Example configuration:

Reveal.initialize({
  //...
  "reveal-leap-motion": {
    naturalSwipe: false,     // Invert swipe gestures
    pointerColor: '#d80000', // Red pointer
    pointerOpacity: 0.5,     // Set pointer opacity to 0.5
  },
});

Supported Gestures

Index Finger Only

When a single index finger is extended, a circular pointer will appear on screen, which tracks the finger. Moving closer to the device expands the pointer.

Multiple Fingers with One Hand

Navigate through the slides by swiping up, down, left, or right. See the config options to invert movements.

Two Hands

Swiping upwards with two hands will toggle the overview mode. A second swipe will exit the overview.
