Buildings viewed through the window of another high building sometimes appear to shrink when we walk towards them. We refer to this phenomenon as the 'shrinking building illusion' and conducted a quantitative investigation to elucidate its underlying mechanisms. We created a virtual scenario to test the illusion using three-dimensional computer graphics. After viewing a movie in which the camera moves forward or backward in relation to the buildings, the participants adjusted the size of the test stimulus to the perceived size of the building in the movie. The results revealed that this illusion cannot be induced by two-dimensional factors alone, such as relative motion and size-contrast. Rather, the illusion appears to be strongly associated with self-motion.
当我们朝着透过另一座高楼窗户看到的建筑物走去时，它们有时看起来会缩小。我们将这种现象称为“建筑物缩小错觉”，并进行了定量研究以阐明其潜在机制。我们使用三维计算机图形创建了一个虚拟场景来测试这种错觉。在观看了一个相机相对于建筑物向前或向后移动的电影后，参与者将测试刺激的大小调整为电影中建筑物的感知大小。结果表明，这种错觉不能仅由二维因素诱发，例如相对运动和大小对比。相反，这种错觉似乎与自我运动密切相关。
