title: Detecting swipe gesture direction with Leap Motion
body: <p>I'm trying to simply get the direction of a swipe gesture with the Leap Motion using the javascript API.  My code is:</p>
  
  <pre><code>$(document).ready(function() {
      controller = new Leap.Controller("ws://localhost:6437/");
      listener = new Leap.Listener();
  
      listener.onFrame = function(controller) {
          var frame = controller.frame();
          var hands = frame.hands();
          var pointables = frame.pointables();
  
          var gestures = frame.gestures();
  
          $("#rotationAxis").text(pointables.length);
          $("#gestureDetected").text(gestures[0]);
      }
  
      controller.addListener(listener);
      controller.enableGesture("swipe", true);
      listener.onConnect = function(controller) {
          // calibrate = new Leap.Calibrate(controller);
          // calibrate.onComplete = function(screen){
          // }
      }
  });
  </code></pre>
  
  <p>I can get the current gesture from the array, but cannot get the type or direction.  Any ideas?</p>
  
  <p>Thanks.</p>
