用于测量眼球运动的设备通常必须针对个体受试者进行校准。一些测量眼睛位置的方法是非常非线性的，需要系统的输出被线性化。我们描述了一种方法的行为校准和线性化，利用跟踪运动目标。该方法的关键方面是使用水平移动目标的跟踪来校准垂直眼睛位置，反之亦然。这种方法对于猫来说特别方便，因为猫对偏心固定目标的固定通常是不可靠的。它允许人们获得准确的校准，而不必判断跟踪扫视是否可靠地击中目标。
Equipment used to measure eye movements must generally be calibrated to the individual subject. Some methods of measuring eye position are quite non-linear, requiring that the system's output be linearized. We describe an approach of behavioral calibration and linearization that utilizes tracking of moving targets. The key aspect of this approach is to use tracking of horizontally moving targets to calibrate vertical eye position and vice versa. This method is especially convenient for use with cats, whose fixation of eccentric stationary targets is often unreliable. It allows one to obtain an accurate calibration without having to judge whether or not tracking saccades reliably hit the target.
