Abstract :
Mental workload (MWL) has been an important concept in Human Factors. In a human-machine system, MWL can explain operator errors at times. MWL is commonly measured by electrocardiography and electroencephalography, but during real-world tasks problems such as noise intrusion make it difficult to estimate mental workload using physical signals. Therefore, the aim of this study was to propose an evaluation index for MWL based on pursuit eye movement. It was examined for participants to follow two kinds of gaze points presented on a rear projector. As a result, it was shown that we experimentally confirmed the effectiveness of the proposed pursuit saccadic intrusions (PSIs) evaluation index, and suggested that it can be used to estimate MWL from pursuit eye movement.
