    KinectCAD

    KinectCAD

    Gesture based movement with CATIA

    This project provides a gesture based movement of part objects in the CAD-system CATIA. It is possible to rotate, move or zoom in or out. Further there is a rudimentary speech recognition to change the rotating axes or to do some other helpful things. KinectCAD has been written in Visual C# 2010. The package includes the source code and binaries files. To start KinectCAD it is necessary to have a correct installed Microsoft Kinect. Also it is helpful if there is an installed Kinect SDK V1. But you can also download the Runtime at: http://download.microsoft.com/download/E/E/2/EE2D29A1-2D5C-463C-B7F1-40E4170F5E2C/KinectRuntime-v1.0-Setup.exe Important! The program is still in development! In future there will be several updates. Until now there is a handbook and several other documents to understand KinectCAD which are not translated to english but in the near future I will translate them. http://www.youtube.com/watch?v=A3ZYCyCt75g If there are questions or problems mail me.
