在真实的世界中，人们在判断到环境中的位置的距离方面是相当准确的，至少对于位于地平面上的目标和大约20 m的距离。在视觉沉浸式环境中的距离判断要不那么准确。一些研究表明，在视觉沉浸式环境中，世界看起来比预期的要小得多。本研究调查是否压缩在表观距离是在以前的调查中使用的低质量的计算机图形的结果。视觉导向的三角形步行被用来评估距离判断在真实的世界和三个虚拟环境中的图形渲染质量不同。
In the real world, people are quite accurate in judging distances to locations in the environment, at least for targets resting on the ground plane and distances out to about 20 m. Distance judgments in visually immersive environments are much less accurate. Several studies have now shown that in visually immersive environments, the world appears significantly smaller than intended. This study investigates whether or not the compression in apparent distances is the result of the low-quality computer graphics utilized in previous investigations. Visually directed triangulated walking was used to assess distance judgments in the real world and in three virtual environments with graphical renderings of varying quality.
