How to track two skeletons with kinect??

Question

I'm doing a project (game pong) to college. I can recognize one skeleton and make gestures to control one painel. I searched and I tried to recognize two skeletons to control the another painel, but I can't do it.

 This is what I have so far:

private void SensorSkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e)
        {
            Skeleton[] skeletons = new Skeleton[0];

            using (SkeletonFrame skeletonFrame = e.OpenSkeletonFrame())
            {
                if (skeletonFrame != null)
                {
                    skeletons = new Skeleton[skeletonFrame.SkeletonArrayLength];
                    skeletonFrame.CopySkeletonDataTo(skeletons);
                }
                if (skeletons.Length != 0)
                {
                    foreach (Skeleton skel in skeletons)
                    {
                        if (skel.TrackingState == SkeletonTrackingState.Tracked)
                        {
                            this.tracked(skel);
                        }
                    }
                }
            }
        }

        public void tracked(Skeleton skeleton)
        {
            Joint jHandRight = skeleton.Joints[JointType.HandRight];
            Joint jHipCenter = skeleton.Joints[JointType.HipCenter];
            if ((jHipCenter.Position.Z - jHandRight.Position.Z) > 0.2)
            {
                //Consider hand raised in front of them
                //System.Diagnostics.Debug.WriteLine("Hand: Raised");
                //MessageBox.Show("POR FAVORRRRRRRR");
                //movement[0] = false;
                movement[0] = true;
                movement[1] = false;
            }
            else
            {
                //Hand is lowered by the users side
                //System.Diagnostics.Debug.WriteLine("Hand: Lowered");
                //MessageBox.Show("A SERRRRIIIIIOOOOOOOOOOOOOO");
                //movement[1] = false;
                movement[1] = true;
                movement[0] = false;
            }
        }

Anyone could help me, please.

There is a logic problem in your code

foreach (Skeleton skel in skeletons)
{
  if (skel.TrackingState == SkeletonTrackingState.Tracked)
  {
    this.tracked(skel);
  }
}

You must define a way to distinguish one skeleton to another and do a specific action for each.

For example, you can use the global skeleton position to define which panel has to be control by the skeleton.

foreach (Skeleton skel in skeletons)
{
  if (skel.TrackingState == SkeletonTrackingState.Tracked)
  {
    if (skel.Position.X < 0) // user on the left side
      this.controlLeftPanel(skel);
    else // user on the right side
      this.controlRightPanel(skel);
  }
}
