For our prototype we have developed an add-in for MS Powerpoint which will be the interface for the user.
As previously mentioned we have decided to use Java. It turns out that in order to use the SDK for the Kinect which requires C#/C++ we have to use the a plug-in (Jnect). It creates a interoperability between the MS SDK and Java.
So far our problems is to connect our interface to the Java code. It seems that MS Powerpoint only supports C#/C++ for add-ins. We are currently considering to rewrite our code in C# because of their similar nature.
For those who missed our presentation last week you can find it here.
