The gazing area and gazing target of an operator during spur road construction were analyzed using an eye camera. The gazing points were distributed toward the right side from the center of the visual field. Gaze constituted 32% of the observation time, and the remaining was saccades. This gaze occupation ratio was lower than that previously reported for driving cars and trains. In total, 67% of the gazing was distributed within the effective visual field. The targets that were the most gazed were bucket (and the periphery of bucket). The gazing frequency was 23.5% and the gazing time was 15.8%. However, these values were lower than those previously reported for excavation-turning-loading work on a flat plane using an excavator.
