In order to simulate the angular velocity, acceleration and other kinematic parameters during the training timely for the ski athletes, we design a three-dimensional motion simulation system based on the gesture information acquisition system, which can help team coach to analyze the action and guide the team members training with the given purpose.Since it is difficult to get the accurate position parameter of the ski athlete, we integrate the ski field and physical information.The gesture information acquisition system can gain the parameter information of three-dimensional acceleration and angular velocity, which are recorded by the sensor.In this paper, we construct a three dimensional motion simulation system to achieve the parameters of velocity, angular acceleration and angle at any time.The three-dimensional motion simulation system for freestyle skiing aerials is constructed in the OpenGL environment, and can observe the effects of posture demonstration from different views.Simulation results show that this system can record the movement information accurately and help athlete obtaining the training targets.
