Relationships between Oculo-Motor Mesures as Task-evoked Mental Workloads During an Manipulation Task

摘要

The frequency of microsaccades is often used as a measurement of eye movement in order to estimate the level of a cognitive mental workload during an experimental task. When the experiment includes several levels of manipulation tasks, ocular information including microsaccades, saccades and pupil diameters can be measured and compared. The results show that the microsaccade rate reflects a participant’s subjective impressions. In addition to measurements of oculomotors, microsaccade rates also reflect the level of effort required by a mental workload, and the mutual relationships between these rates are analyzed using causal analysis.
