In this approach, the feedback of the prototype is presented to a gamer - expert in Kinect games, that will assess if the prototype has given a correct feedback or not regarding the gestures. Every correct gesture that the prototype identifies is a point "Check". Otherwise, a point "Cross" is given. After collecting the points, the formula used to compute for the accuracy rate is computed as follows:    \begin{equation*}{{ ACC }_{ prototype }\quad =\quad \frac { Ch }{ N Total  } \times \quad 100}\end{equation*}
