Visual motion perception plays a fundamental role in vehicle control. Recent studies have shown that the pattern of optical flow resulting from the observer's self-motion through a stable environment is used by the observer to accurately control his or her movements. However, little is known about the perception of another vehicle during self-motion--for instance, when a car driver approaches an intersection with traffic. In a series of experiments using visual simulations of car driving, we show that observers are able to detect the presence of a moving object during self-motion. However, the perception of the other car's trajectory appears to be strongly dependent on environmental factors, such as the presence of a road sign near the intersection or the shape of the road. These results suggest that local and global visual factors determine the perception of a car's trajectory during self-motion.
视觉运动感知在车辆控制中起着至关重要的作用。最近的研究表明，观察者在稳定环境中自我运动所产生的光流模式被观察者用来精确控制其动作。然而，对于自我运动过程中对另一辆车的感知却知之甚少——例如，当汽车驾驶员接近有交通的十字路口时。在一系列使用汽车驾驶视觉模拟的实验中，我们表明观察者能够在自我运动过程中检测到移动物体的存在。然而，对另一辆车轨迹的感知似乎强烈依赖于环境因素，比如十字路口附近的路标存在与否或道路的形状。这些结果表明，局部和全局视觉因素决定了自我运动过程中对汽车轨迹的感知。
