Research on indoor multi-degree-of-freedom ski training system

In this paper, a multi-freedom ski training system is introduced for indoor alpine skiing training and entertainment. The translation platform and the six-degree-of-freedom platform are adopted in the system to realize a wide range of slalom training and terrain simulation. Combining the washout algorithm with the virtual scene and terrain information in Unity3D, the system provides users with the real physical and visual experience of alpine skiing. In the design of washout algorithm, sparrow search algorithm (SSA) is used to optimize the parameters of washout filter, which can achieve a less sensation error and a higher efficiency of the workspace usage. Simulation and experimental results show that our system can give users a real alpine skiing experience, and facilitate the users to ski training and experience the terrain of the ski trail.
