Kinect for Windows: Find user height accurately

I have been a student at Athens University of Economics and Business, Department of Informatics, since September 2007.
 
I mainly develop and design .NET applications in C#, ASP.NET and Silverlight, but I have also worked on J2EE, LAMP and C++.
 
Currently, I am a member of Microsoft Student Partners team and I work as a freelancer for several employers including the Institute for the Management of Information Systems and Vodafone Corporation. As a Student Partner, I have made lots of speaking engagements considering Microsoft technologies (ASP.NET, Silverlight, Windows Phone etc) to undergraduate / postgraduate students and developers.
