婴儿眼动追踪因其相对于传统注视时间范式的假定精度和对发育过程产生新见解的潜力而变得越来越受欢迎。然而，有充分的理由怀疑流行的眼动跟踪系统的时间和空间分辨率并不完全准确，可能会损害婴儿眼动跟踪实验的任何数据。此外，婴儿眼动追踪的最佳实践，例如了解哪种软件工具可以增强实验的灵活性，仍有待确定。本研究旨在通过使用成人和婴儿的视觉潜伏期和空间准确性任务来评估Tobii T60XL眼动仪数据的时间和空间准确性。系统的延迟和漂移被发现在oculeclampus的响应时间，和系统的空间精度被观察到偏离有点超过制造商的估计，该系统的实验灵活性似乎取决于所选择的软件。
Infant eye tracking is becoming increasingly popular for its presumed precision relative to traditional looking time paradigms and potential to yield new insights into developmental processes. However, there is strong reason to suspect that the temporal and spatial resolution of popular eye tracking systems is not entirely accurate, potentially compromising any data from an infant eye tracking experiment. Moreover, best practices for infant eye tracking, such as knowing which software tool enhances experimental flexibility, remain to be determined. The present investigation was designed to evaluate the temporal and spatial accuracy of data from the Tobii T60XL eye tracker through the use of visual latency and spatial accuracy tasks involving adults and infants. Systematic delays and drifts were revealed in oculomotor response times, and the systems spatial accuracy was observed to deviate somewhat in excess of the manufacturers estimates; the experimental flexibility of the system appears dependent on the chosen software.
