当使用眼动技术研究信息负荷时，有趣的变量是注视的持续时间和扫视和眨眼的次数。这些可以通过眼电图和角膜反射技术来测量。为了确保两种方法在研究中具有相同的信息源，同时使用设备。源是由固定的目标形成的。受试者的头部保持自由，模拟现场条件。研究结果表明，两种方法都可以准确地确定眨眼的次数。角膜反射技术未发现微扫视，但更容易发现扫视。
When the informatory workload is studied using eye-movement technique, the interesting variables are duration of fixations and the number of saccades and blinks. These can be measured by electro-oculography and corneal reflection techniques. To ensure that both methods had the same information source in the study, the equipment was used simultaneously. The source was formed by fixed targets. The subject's head was left free, simulating field conditions. The results of the study indicate that the number of blinks could be determined exactly by either method. With corneal reflection techniques, microsaccades were not found, but saccades were found more easily.
