First, a specific set of correct hand gestures are were  specified by the researchers before-hand. These hand gestures are were  used to be able to correctly define the only hand gestures to be recognized by the system. In the gesture recognition, the gestures are were  classified into their corresponding gestures for comparison. The use of collision detection algorithm to enhance the gesture recognition capability of our motion tracking system is was  applied only in the actual processing module. Both with and without collision detection for gesture recognition produces a data model, wherein a correct gesture is was  known as a hit, otherwise, miss, that is was  used as basis for comparison in the system’s overall accuracy and performance.\\ The mention aforementioned  collision detection algorithm worked was applied using the approach of \citet{cohen1995collide}'s  in two level phases their study. Figure \textbf{blank} shows the collision detection module.
