观察者如何感知旋转过程中的自我运动路径？先前的研究表明，在高旋转速率（2-5度/秒）下，有关眼球运动的视网膜外信息是必要的，但这些实验使用稀疏随机点显示。与密集的纹理映射的显示器，我们发现的路径可以被认为是从视网膜流单独在高模拟旋转率，如果（a）密集的运动视差和（B）至少有一个参考对象是可用的。我们建议，视觉系统从一阶运动视差场确定瞬时航向，并通过随时间更新航向来恢复场景中的参考物体的自运动路径。(C)2000爱思唯尔科技有限公司版权所有。
How do observers perceive the path of self-motion during rotation? Previous research suggests that extra-retinal information about eye movements is necessary at high rotation rates (2-5 degrees /s), but those experiments used sparse random-dot displays. With dense texture-mapped displays, we find the path can be perceived from retinal flow alone at high simulated rotation rates if (a) dense motion parallax and (b) at least one reference object are available. We propose that the visual system determines instantaneous heading from the first-order motion parallax field, and recovers the path of self-motion by updating heading over time with respect to reference objects in the scene.
