Question

I need to make a cursor in Kinect, but I don’t know where to start. I need to make it using WPF and C#. Cursor should be in shape of hand and when I hover over element the “loading” circle should appear, and when it “loads” it should fire click event on hovered element.
I’m sure that your’re all familiar with this.

It would be of great help if someone could write me some directions oh how to accomplish this.

Here is a code snippet that might help you:

using Microsoft.Research.Kinect.Nui;

Runtime nui = Runtime.Kinects[0];
nui.Initialize(RuntimeOptions.UseSkeletalTracking);
nui.SkeletonFrameReady += new EventHandler<SkeletonFrameReadyEventArgs>(nui_SkeletonFrameReady);

void nui_SkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e)
{
    SkeletonFrame sf = e.SkeletonFrame;
    SkeletonData d = (from s in sf.Skeletons
                      where s.TrackingState == SkeletonTrackingState.Tracked
                      select s).FirstOrDefault();

     if (d != null)
     {
          SetHandPosition(imageCursor, d.Joints[JointID.HandLeft]);
     }
}

void SetHandPosition(FrameworkElement e, Joint joint)
{
    Joint scaledJoint = Coding4Fun.Kinect.Wpf.SkeletalExtensions.ScaleTo(joint, 600, 400, 0.75f, 0.75f);

    Canvas.SetLeft(e, scaledJoint.Position.X);
    Canvas.SetTop(e, scaledJoint.Position.Y);
} 

If you want your cursor to be different hovering on an element then just go to the elements properties and set a cursor for that element. In Visual Studio you can choose a cursor in the elements properties.

To make a click on a hover over an element you have to implement the MouseEnter event

private void button1_MouseEnter(object sender, MouseEventArgs e)
{
....        
}

Here are some infos about it:
