Abstract

<p>Operators who engaged in vessel traffic services provide a variety of information to vessels in order to enhance the safety and efficiency of marine traffic. In this study, fixation time of the operator’s eye were analyzed using two eye tracking devices to investigate the real work of VTS operators, who are usually two-person teams at Shimizu Port Radio. The results of analysis with equipment and materials as area of interest in the operation room showed a tendency for the division of work to be determined by the arrangement of equipment. It was confirmed that the time spent looking at the display showing various relevant information of VTS was about half of the time spend on the job, compared with maritime observation and document reading. Also, the operators simultaneously preparing documentation while were communicating via VHF, suggesting that workspace was an important aspect. From the viewpoint of improving the operator's work environment, we also consider importance to design the monitor and equipment layout.</p>
