The Relationship between Psychological Workload and Oculomotor Indices under Visual Search Task Execution

Tomomi Okano, Minoru Nakayama

Abstract

In this paper, we have focused especially on microsaccade and pupil diameter to extract relationships with psychological workload. We measured how these oculomotor feature values changes to 10 subjects when executing visual search tasks containing psychological workload. To evaluate the amount of psychological workload, we used a systematic evaluation index, NASA-TLX and analyzed by combining pupil movements with answer rate and difficulty of both tasks. As a result, we have discovered that by the difference of psychological workload and 2 experimental conditions, microsaccade frequency and task performance changes.
