In recent years,  Research and developmentin recent years  has made the inclusion involvement  of individuals with a physical or cognitive disability into the  society much easier, helping serving for  them in the realization to be aware  of their daily activities, thus increasing expanding  their autonomy and self-confidence \citet{domingo2012overview}. \cite{domingo2012overview}.  Human body part detection and tracking has a wide extensive  range of applications. In the past, camera-based Camera-based  motion capture systems system  that required cumbersome markers or suits were used. used in the past.  With this, multi-camera systems \citet{plagemann2010real} \cite{plagemann2010real}  or binocular cameras \citet{hrabar2009high} \cite{hrabar2009high}  can be used. As said in the previous articles, The the  Kinect device interprets the 3D information data  of the scene obtained gotten  through infrared structured light that is read by a standard CMOS sensor. It was designed outlined  to allow users to interact cooperate  with the gaming system without the need for a traditional classical  hand held controller. Instead, the sensor recognizes distinguishes  the user’s gestures. There are Two two  stages that  are included in the system as showed indicated  in Fig. 9: skeleton detection stage identification phase  and exercises monitoring stage. \citet{gonzalez2014kinect} stage \cite{gonzalez2014kinect}.
