How to handle left/right/up/down swipes for the Leap Motion controller

amd-config.js

require.config({
    paths: {
        leap : '//js.leapmotion.com/0.2.0/leap'
    },
    shim: {
        exports: 'Leap'
    }
});

define(['leap'], function(Leap) {
    Leap.loop();
});

swipes.js

Leap.loop({enableGestures: true}, function(frame)
{
    if (frame.gestures.length > 0) {
        var g = frame.gestures[0];
        if (g.type === 'swipe' && g.state === 'stop') {
            // Get the absolute movement along the x and y axis
            var xMov = Math.abs(g.direction[0]);
            var yMov = Math.abs(g.direction[1]);
            if (xMov > 0.3) {
                if (g.direction[0] < 0) {
                    onLeftSwipe();
                }
                else {
                    onRightSwipe();
                }
            }
            else if (yMov > 0.3) {
                if (g.direction[1] < 0) {
                    onDownSwipe();
                }
                else {
                    onUpSwipe();
                }
            }
        }
    }
}
