Interactions between visual system of space and vergence system

本研究的目的是从理论和实验上阐明空间视觉系统与运动系统，特别是聚散度系统之间的关系。本研究有两个目的：（1）阐明处理物体相对距离、绝对距离和大小的视觉系统与聚散度系统之间的关系;（2）在第一个目的的基础上，从理论上阐明视觉系统的“功能原理”。从1998年到2000年进行的几个实验表明：（a）视觉系统在双眼视轴平行之外的发散状态下校准感知深度、感知大小和感知距离;（B）视觉系统使用绝对距离信息校准由双眼视网膜视差、视差梯度和运动视差获得的相对深度;因此，双眼立体视觉和单眼立体视觉中的感知深度随着感知自我中心距离的增加而增加。我们将此函数命名为深度缩放原理。我们提出的第二个原则是“双眼视觉感受原则”，它指出视觉系统在任何情况下都会整合来自双眼的视觉输入，以产生单一的视觉感受。

The aim of this study was to clarify theoretically and experimentally the relationships between visual system of space and motor system, specifically the vergence system. There were two sub-purpose : (1) to clarify the relationships between the visual system to process relative distance, absolute distance, and size of objects and the vergence system, and (2) based on the results of the first purpose, to clarify theoretically "functional principles" of the visual system. The several experiments conducted from 1998 to 2000 indicated that : (a) the visual system calibrates perceived depth, perceived size, and perceived distance in divergence states beyond parallelism of visual axes of both eyes, (b) the visual system calibrates relative depth obtained from binocular retinal disparity, disparity gradient, and motion parallax, using absolute distance information ; consequently, the perceived depth in binocular stereopsis and monocular stereopsis increases as the perceived egocentric distance increases. We named this function the principle of depth scaling. The second principle we made is "cyclopean percept principle", which states that the visual system integrates visual inputs from both eyes to make single percept in any situations viewed binocularly.
