Previously, eye positions were characterized by the direction of sight, which has two degrees of freedom for conjugate movements and three degrees of freedom for vergent movements. Several groups have recently presented reliable data and unconventional models on binocular coordination, where all three degrees of freedom for one or both eyes have been taken into account. The results illustrate Bernstein's principle that in order to simplify control, the brain establishes unique relations between the target and motor space, in which non-Euclidean geometry of rotations is observed.
以前，眼睛位置是通过视线方向来表征的，对于共轭运动有两个自由度，对于辐辏运动有三个自由度。最近有几个研究小组给出了关于双眼协调的可靠数据和非常规模型，其中考虑了一只或两只眼睛的所有三个自由度。结果说明了伯恩斯坦原理，即大脑为了简化控制，会在目标和运动空间之间建立独特的关系，其中观察到旋转的非欧几里得几何。
