	This project can interact with the particle system by acquiring the skeleton of the moving visitors through the tracking system. We use the particle system to express it with large or small group of ants, at the same time, acquire the six key points of the skeleton in the tracking system, head, left hand, right hand, left foot, right foot, Spine1, and connect these six with lines, making it appear as a basic human skeleton shape.

	Our interactive particle system project is based on the motion tracking system to obtain the data of skeleton movements of the visitors to manipulate the effects of the particle system (including Head, LeftHand, RightHand，LeftFoot, RightFoot, Spine1), in order to achieve this goal, we are starting decoding our programming part step by step: First of all, we know that the data of the above parts of the skeleton obtained from the motion tracking system is just one point. The two parts of the hands constitute two vectors, then the head data is used as the connection point of the hands. if we want to realize the effect of repelling away between particles and connected vector, We must keep the distance between each particle in the particle system to the two vectors bigger than a certain value, maybe the radius of the ellipse(point). Therefore, we decompose the two vectors into points separated by a certain distance and decode this into the distance from particles to these points which cannot smaller than a specific value.
