Research on a Washout Algorithm for 2-DOF Motion Platforms

摘要

This paper proposes a new washout algorithm optimized from those designed for 6-DOF Stewart platforms using the Human Vestibular Based Strategy. Its actual effect, from the perspective of user experience, was verified via a within-subject design experiment using a 2-DOF platform with limited rotation angles. The result showed that compared with the common 2-DOF algorithms using the Linear Shrinkage Ratio Strategy, our algorithm provided users with better immersion, presence and overall satisfaction, though no significant difference was found regarding simulator sickness. This positive result demonstrated the potential of the algorithm proposed here and may help to enhance the user experience of various kinds of motion platforms.
