How can I make Reveal.js work with a presenter remote?

What you want is that it would navigate to "next" instead of "right", which is the default binding for right arrow key. You can achieve this by overriding the default key bindings. There is some documentation here: https://github.com/hakimel/reveal.js/#keyboard-bindings

In your case you would like the right arrow key (keycode 39) to bind to "next" and probably also override left arrow key (keycode 37) to bind to "prev". Here is the sample code (add this to the Reveal.initialize configuration add the end of the file):

keyboard: {
    39: 'next',
    37: 'prev'
}

reveal.js has a built in remote! If you take a look at dependencies in the README, the very last item in Reveal.initialize is the option to activate a remote! It'll pop up a QR code that you can scan; the website it takes you to syncs with your presentation (over the internet, not local wifi/bluetooth) and allows you to control your presentation with your touchscreen device. There is even an app (for iOS) streamlined specifically for using the remote, I believe it's called RemotesLite.

When using the remote, a tap is equivalent to your spacebar, swipes left/right/up/down are left/right/up/down, and pinch in/out is overview mode activate/deactivate.

Hope this helps!

UPDATE 4/21/2014

It appears as if the most recent version of Reveal has built-in presenter remote support. Recently gave a presentation with a Targus presentation remote and it worked out of the box!
