In the recent years, research and development in technology has helped involve many individuals with physical or cognitive disability to fit in the society much easier, making them more aware of their daily activities, and thus expanding their autonomy and self-confidence \cite{domingo2012overview}. It has been said again and again that human body part detection and tracking has an extensive range of applications. Camera-based motion capture system that require cumbersome markers or suits were used in the past. Nowadays, multi-camera systems \cite{plagemann2010real} or binocular cameras \cite{hrabar2009high} are being used specifically for motion capture technology since they provide a more robust representation of 3d data. As said in the previous articles, the Kinect device interprets the 3D data of the scene gotten through infrared structured light that is read by a standard CMOS sensor. It was outlined to allow users to cooperate with the gaming system without the need for a classical hand held controller. Instead, the sensor distinguishes the user’s gestures. According to \citet{gonzalez2014kinect},, \citet{Gonz_lez_Ortega_2014},,  there are two stages that are included in the motion capturing technology of Kinect (See Figure 8).
