@El Pibe: While it technically wouldn't be through your Kinect, you can use Text-To-Speech (TTS) to have a computerized-style voice talk back to you. The TTS engine is built into Microsoft.Speech APIs

Paul — Tue, 26 Jul 2011 16:32:04 GMT

What's the trick to getting:
1) The player index to activate and
2) The joints to establish tracking?

I have to gesticulate wildly to accomplish either of these, and it doesn't happen reliably. Somehow, it doesn't seem deterministic.

Awesome Dan,

Thank you for the samples and I have been able to create an application using this and control through hand gestures :). Works great and everyone liked it.

Now cant wait for the release version of the SDK. Sure you guys must have lots of advancements.

I failed to find more information on TransformSmoothParameters and ScaleTo on how to control the distance from the sensor and still be able to render a standard size skeleton everytime.

Appreciate if you can share something on this.

Hi, I have a problem, I try running this code sample using c # and KinectForWindowsSDKQuickstarts I have the following error:

WAS NullReferenceException unhandled by user code.

In the line:

SetEllipsePosition (headEllipse, skeleton.Joints [JointID.Head]);

I have no problem with the other examples just this.

thanks for your help

Re: Skeletal Tracking Fundamentals (Beta 2 SDK)

Firdosh Tangri — Fri, 19 Aug 2011 22:58:49 GMT

@Omar - Thats because when you start the app none of the Skeletons are being tracked so the skeleton variable is null. This should fix it

//set position
if (skeleton != null)
{
SetEllipsePosition(headEllipse, skeleton.Joints[JointID.Head]);
SetEllipsePosition(leftEllipse, skeleton.Joints[JointID.HandLeft]);
SetEllipsePosition(rightEllipse, skeleton.Joints[JointID.HandRight]);
}

Cheers,
Firdosh

Thanks, these tutorials are great.

How would I go about changing the color of an ellipse with hand movement? Here's what I have so far:

private void SetEllipseProperties(FrameworkElement ellipse, Joint joint)
        {
            var scaledJoint = joint.ScaleTo(640, 480, .5f, .5f);

            // change position
            Canvas.SetLeft(ellipse, scaledJoint.Position.X);
            Canvas.SetTop(ellipse, scaledJoint.Position.Y);
           
            //change color
            ellipse.Fill = someColorFunction(scaledJoint.Position.Y);
            
        }

but it doesn't like ellipse.Fill. It tells me "System.Windows.FrameworkElement' does not contain a definition for 'Fill' and no extension method 'Fill' accepting a first argument of type 'System.Windows.FrameworkElement' could be found (are you missing a using directive or an assembly reference?)", yet here, myEllipse.Fill is directly changed.

I'm very new at this -- any help is appreciated!

Got everything working. I'm still learning C#, but I did figure out how to add different joints, change the ellipses to rectangles and change colors, etc.
Now on to bigger and better things. I'd like to add a button to the window and the right hand ellipse hovers over it, that would then activate the click event (like it does on the XBox).
I'll be working on that, but right now, I have no idea how to do it, but any suggestions would be appreciated!!

For everybody having issues with the ScaledTo function, it's included in the "Coding4Fun Kinect Toolkit" located here: http://c4fkinect.codeplex.com/

The actual code is this:
public static Joint ScaleTo(this Joint joint, int width, int height, float skeletonMaxX, float skeletonMaxY)
{
Vector pos = new Vector()
{
X = Scale(width, skeletonMaxX, joint.Position.X),
Y = Scale(height, skeletonMaxY, -joint.Position.Y),
Z = joint.Position.Z,
W = joint.Position.W
};

Joint j = new Joint()
{
ID = joint.ID,
TrackingState = joint.TrackingState,
Position = pos
};

return j;
}

public static Joint ScaleTo(this Joint joint, int width, int height)
{
return ScaleTo(joint, width, height, 1.0f, 1.0f);
}

private static float Scale(int maxPixel, float maxSkeleton, float position)
{
float value = ((((maxPixel / maxSkeleton) / 2) * position) + (maxPixel/2));
if(value > maxPixel)
return maxPixel;
if(value < 0)
return 0;
return value;
}

Hope the formatting turns out OK.
