Example of SkeletonTracking

gistfile1.cs

var st = new SkeletonTracking();

//If you want to know if a skeleton is currently being tracked by the Kinect
//SkeletonPresent produces a "True" value every time the Kinect changes from
//not tracking anyone and a "False" if there is no longer anyone to track
st.SkeletonPresent.Subscribe(
	p =>
	{
		if (p)
			Console.ForegroundColor = ConsoleColor.Green;
		else
			Console.ForegroundColor = ConsoleColor.Red;
	});

//If you want to track individual skeletons FreshSkeletons produces a
//value every time there is at least one new skeleton to track and each
//skeleton gets its own IObservable stream which will complete when that
//skeleton is no longer being tracked.
st.FreshSkeletons.Subscribe(
	skels =>
	{
		Console.WriteLine("{0} fresh skeletons produced", skels.Count());
		foreach (var skel in skels)
		{
			skel.Subscribe(
					s => Console.WriteLine("Skeleton with Id {0} produced a value.", s.TrackingID),
					() => Console.WriteLine("Skeleton is no longer being tracked.")
				);
		}
	});
