通过三个实验研究了绝对高度的眼高（EH）标度。在实验1中，站着的观察者在沉浸式虚拟环境中观看立方体。观察者的投影中心分别位于实际EH和0.7倍实际EH处。观察者的大小判断显示EH操纵有效率为76.8%。在实验2中，坐着的观察者在交互式桌面显示器上观看相同的立方体；然而，EH对模拟EH操作没有影响。实验3测试了沉浸式环境中的站立观察者，视野缩小到与桌面相当。与实验1比较，EH的效果为77%。这些结果表明，当人们观看交互式桌面显示器时，通常不使用EH缩放，因为投影中心的高度不确定。然而，在沉浸式环境中，EH缩放会自发地被唤起。
Eye-height (EH) scaling of absolute height was investigated in three experiments. In Experiment 1, standing observers viewed cubes in an immersive virtual environment. Observers' center of projection was placed at actual EH and at 0.7 times actual EH. Observers' size judgments revealed that the EH manipulation was 76.8% effective. In Experiment 2, seated observers viewed the same cubes on an interactive desktop display; however, no effect of EH was found in response to the simulated EH manipulation. Experiment 3 tested standing observers in the immersive environment with the field of view reduced to match that of the desktop. Comparable to Experiment 1, the effect of EH was 77%. These results suggest that EH scaling is not generally used when people view an interactive desktop display because the altitude of the center of projection is indeterminate. EH scaling is spontaneously evoked, however, in immersive environments.
