XKin is an open source library that enables users to build hand gesture based applications employing Kinect sensor. Hand Gesture recognition comes in two ways: static hand pose (posture) and dynamic hand movement (gesture). For this purpose this package provides four libraries:

• libbody (body detection)

• libhand (hand detection and contour extraction)

• libposture (posture classification)

• libgesture (hand trajectory movement classification)

This package comes also with some useful tool for training and testing the models (posture and gesture).

This package provides also some demostration videos of two simple gesture applications that comes with XKin. One video shows a posture based application which is an implementation of the rock papper scissor game.

The other video illustrates a gesture based application. In this case is implemented a basic image gallery application, the interaction is done by using four gesture that enable the user to perform zoom (in/out) navigation (previous/next) operations.

In order to compile XKin you will need:

• cmake (>=2.6)

• libfreenect (https://github.com/OpenKinect/libfreenect)

• OpenCV (http://sourceforge.net/projects/opencvlibrary/files)

• fftw (http://www.fftw.org/download.html)

This procedure use ccmake, the console gui of cmake, to configure the project and generate unix makefiles for compilation:

• cd to the source folder

• mkdir a directory like build/ and cd to that

• type ccmake .. (sometimes configuration may fail if some library dependencies is installed in a non standard path, from the gui it’s possibile to specify manually libraries and include)

• type make (compile all the stuff)
