A study is reported of the effect of dynamic occlusion that arises during locomotion over corrugated surfaces and its facilitating role on the control of locomotion, especially in cluttered environments. Surfaces varied in degree of corrugation and type of texture. Heading accuracy was assessed by having participants perform an active steering task. Results demonstrated the advantage of texture-mapped image surfaces over discrete element surfaces in the corrugated conditions. Observers appear to exploit accretion and deletion of optical texture at the occluding edge to extract and use information about heading direction for the control of movements in cluttered environments.
本文报道了一项关于在波纹表面上运动时产生的动态遮挡效应及其对运动控制的促进作用的研究，特别是在杂乱环境中的运动控制。表面的波纹程度和纹理类型各不相同。通过让参与者执行主动转向任务来评估航向准确性。结果表明，在有波纹的条件下，纹理映射图像表面比离散元素表面更具优势。观察者似乎利用遮挡边缘处光学纹理的增减来提取和使用有关航向方向的信息，以控制在杂乱环境中的运动。
