当人类观察者在世界中移动时，他们的眼睛会获得一系列不断变化的图像。来自该序列的信息足以确定3D场景的结构，直到由眼睛移动的距离确定的比例因子。有充分的证据表明，人类视觉系统在判断物体的大小、形状和距离时，会考虑观察者走过的距离和眼睛的分离。然而，使用沉浸式虚拟现实环境，我们创建了一个场景，提供了一致的信息规模从距离步行和双目视觉，但观察者未能注意到，当这个场景扩大或收缩。这一失败导致在判断物体大小时出现很大的错误。错误的模式不能解释假设一个视觉重建的场景与一个不正确的估计眼间距或步行距离。相反，它是一致的贝叶斯模型的线索整合，其中的运动和视差线索的功效是更大的在近观看距离。我们的研究结果意味着，观察者更愿意调整他们的估计眼间距或步行距离比接受场景的大小已经改变。
As a human observer moves through the world, their eyes acquire a changing sequence of images. The information from this sequence is sufficient to determine the structure of a 3-D scene, up to a scale factor determined by the distance that the eyes have moved. There is good evidence that the human visual system accounts for the distance the observer has walked and the separation of the eyes when judging the scale, shape and distance of objects. However, using an immersive virtual reality environment we created a scene that provided consistent information about scale from both distance walked and binocular vision and yet observers failed to notice when this scene expanded or contracted. This failure led to large errors in judging the size of objects. The pattern of errors cannot be explained by assuming a visual reconstruction of the scene with an incorrect estimate of interocular separation or distance walked. Instead, it is consistent with a Bayesian model of cue integration in which the efficacy of motion and disparity cues is greater at near viewing distances. Our results imply that observers are more willing to adjust their estimate of interocular separation or distance walked than to accept that the scene has changed in size.
