Humans can learn to overcome the 150 msec delay of the eye movement system and track predictable targets with no latency. The mean squared error between the target and eye position was used as a measure of the goodness of tracking. For typical subjects, this error decreased from 0.5 deg2 to 0.1 deg2 after 100-200 sec of viewing the target. Professional athletes had much smaller mean squared errors at the beginning of the learning period.
人类可以学会克服眼动系统150毫秒的延迟，并毫无延迟地跟踪可预测目标。目标与眼睛位置之间的均方误差被用作跟踪质量的一种度量。对于典型的受试者，在观察目标100 - 200秒后，这种误差从0.5度²降至0.1度²。职业运动员在学习期开始时的均方误差要小得多。
