In shield construction, it is concerned that the shortage of skilled workers causes serious accident due to oversight of fluctuation and delay in taking action. Therefore, revealing the cognitive processes of experienced shield machine operators is important. In this report, a part of the cognitive processes was revealed by analyzing eye tracking data and control logs of shield machine. Two machine operators were conducted eye tracking test. There were differences in viewpoint between the two operators as a result of comparison of the gaze movements. From Eye tracking and data of control machine, we revealed time lags of recognizing fluctuation and clarified operator’s sequences of estimating manipulation. We will develop operating support system and foster advanced operator in the future.
