A series of experiments were made on human performance in controlling optical relative movement. The aim was to test the influence of different kinds of relative movement on visually controlled steering tasks. Within adjacent displays on a computer screen random dot patterns moved in a fixed direction at continually changing speeds (Exp. 1) or at constant speed and in continually changing directions (Exp. 2). The subject was required to compensate for the unpredictable modulations of the pattern movement by means of an isometric joystick. The task was to adjust relative movements involving pure translation, symmetric convergence, divergence, or shear. Analysis indicated that the task performance was not dependent on the special kind of relative movement. However, performance was significantly higher in tasks where directionally disturbed relative movement had to be controlled compared to those situations in which relative movement varied with respect to speed.
针对人类控制光学相对运动的表现进行了一系列实验。目的是测试不同类型的相对运动对视觉控制转向任务的影响。在计算机屏幕上相邻的显示器内，随机点图案以不断变化的速度沿固定方向移动（实验1），或以恒定速度并沿不断变化的方向移动（实验2）。受试者需要通过等距操纵杆来补偿图案运动不可预测的调制。任务是调整涉及纯平移、对称会聚、发散或剪切的相对运动。分析表明，任务表现并不取决于相对运动的特殊类型。然而，与相对运动速度变化的情况相比，在必须控制方向受干扰的相对运动的任务中，表现明显更高。
