Kinect SDK 1.7 - How to control WPF elements Inside/outside the Kinect Region

I´m trying to work with Kinect SDK 1.7 in WPF and C#.

Is there any option how to control WPF elements - for example WPF button, WPF slider, etc. I cannot find how to do this. When I take a WPF button to Kinect region the KinectPointer doesn´t react with these controls. I thought that this pointer is something like mouse pointer.

Please can you help me, how to do that?

Thank you very much!

This link might help you to Kinectify your own controllers. The example is about a checkbox, but you can extend it to other controllers as well:

public class MyCheckBox : CheckBox
{
    private static readonly bool IsInDesignMode = DesignerProperties.GetIsInDesignMode(new DependencyObject());
    private HandPointer _capturedHandPointer;

    public MyCheckBox()
    {
        if (!IsInDesignMode)
        {
            Initialise();
        }
    }

    private void Initialise()
    {
        KinectRegion.AddHandPointerPressHandler(this, this.OnHandPointerPress);
        KinectRegion.AddHandPointerGotCaptureHandler(this, this.OnHandPointerCaptured);
        KinectRegion.AddHandPointerPressReleaseHandler(this, this.OnHandPointerPressRelease);
        KinectRegion.AddHandPointerLostCaptureHandler(this, this.OnHandPointerLostCapture);
        KinectRegion.AddHandPointerEnterHandler(this, this.OnHandPointerEnter);
        KinectRegion.AddHandPointerLeaveHandler(this, this.OnHandPointerLeave);
        KinectRegion.SetIsPressTarget(this, true);
    }
}

private void OnHandPointerLeave(object sender, HandPointerEventArgs e)
{
    if (!KinectRegion.GetIsPrimaryHandPointerOver(this))
    {
        VisualStateManager.GoToState(this, "Normal", true);
    }
}

private void OnHandPointerEnter(object sender, HandPointerEventArgs e)
{
    if (KinectRegion.GetIsPrimaryHandPointerOver(this))
    {
        VisualStateManager.GoToState(this, "MouseOver", true);
    }
}

private void OnHandPointerLostCapture(object sender, HandPointerEventArgs e)
{
    if (_capturedHandPointer == e.HandPointer)
    {
        _capturedHandPointer = null;
        IsPressed = false;
        e.Handled = true;
    }
}

private void OnHandPointerCaptured(object sender, HandPointerEventArgs e)
{
    if (_capturedHandPointer == null)
    {
        _capturedHandPointer = e.HandPointer;
        IsPressed = true;
        e.Handled = true;
    }
}

private void OnHandPointerPress(object sender, HandPointerEventArgs e)
{
    if (_capturedHandPointer == null && e.HandPointer.IsPrimaryUser && e.HandPointer.IsPrimaryHandOfUser)
    {
        e.HandPointer.Capture(this);
        e.Handled = true;
    }
}

private void OnHandPointerPressRelease(object sender, HandPointerEventArgs e)
{
    if (_capturedHandPointer == e.HandPointer)
    {
        if (e.HandPointer.GetIsOver(this))
        {
            OnClick();
            VisualStateManager.GoToState(this, "MouseOver", true);
        }
        else
        {
            VisualStateManager.GoToState(this, "Normal", true);
        }
        e.Handled = true;
    }
}

KinectPointer is quite different to a normal Mousepointer, it doesn't work with normal WPF Controls out of the box.

please have a look at the Events that are available at the kinect region:

http://msdn.microsoft.com/en-us/library/microsoft.kinect.toolkit.controls.kinectregion_events.aspx

If i'm remembering correctly, the sourcecode for the Kinect Interaction Tookit Controls is included in the SDK, have a look at KinectButtonBase.cs to see how you could develop Kinect-Controls.
