• x - the variable stores x-coordinate of gesture beginning;
• y - the variable stores y-coordinate of gesture beginning;
  

var button; 
IR.AddListener(IR.EVENT_START, 0, function()
// Event is activated at the application launch
{
    // Create a button for switching pages
    var button = IR.CreateItem(IR.ITEM_BUTTON, "text", 10, 10);
    button.Text = "";
     
    // Activating gestures
    IR.AddRecognizer(IR.GESTURE_SWIPE_LEFT);  // Activate gesture SWIPE_LEFT
    IR.AddRecognizer(IR.GESTURE_SWIPE_RIGHT); // Activate gesture SWIPE_RIGHT
    IR.AddRecognizer(IR.GESTURE_SWIPE_UP);    // Activate gesture SWIPE_UP
    IR.AddRecognizer(IR.GESTURE_SWIPE_DOWN);  // Activate gesture SWIPE_DOWN

    // Connect Listener, send the current page and the function with parameters.    IR.AddListener(IR.EVENT_GESTURE_BEGIN, IR.CurrentPage, function(gesture, x, y)
    {
        
        // Choice structure
        switch(gesture)
        {
        case IR.GESTURE_SWIPE_LEFT: 
            button.Text = "Left";   // If you begin a gesture SWIPE_LEFT you see the sign "Left"           
           break;
        case IR.GESTURE_SWIPE_RIGHT:
            button.Text = "Right";  // If you begin a gesture SWIPE_RIGHT you see the sign "Right"
            break;
        case IR.GESTURE_SWIPE_UP:
            button.Text = "Up";     // If you begin a gesture SWIPE_UP you see the sign "Up"
            break;
        case IR.GESTURE_SWIPE_DOWN:
            button.Text = "Down";   // If you begin a gesture SWIPE_DOWN you see the sign "Down"
