Navigator is always obtaining various ship borne as well as environmental data through his five senses. Visual data are among others said to be most effective, numerous and highly utilized ones. It is however authors' acknowledgement that the importance of a role of the visual information in the navigator's decision making process have not yet really recognized and consequently not analyzed fully. And moreover when it comes to how, from what and for what a captain acquires his visual data, research has hardly been done about it. The authors began with the research on the fundamental functions of the eye before concentrating their efforts onto the main issues mentioned above. The experiments were done on the eye movements in fixation process with the eye movement measuring device. Followings are some of our findings: 1. Fixation process was revealed to be highly coordinated movement by both eyes.2. Transient patterns of the eye movements towards the final fixation were observed, in which some takes 10 seconds and another reaches in less than 100 msec. 3. It is also revealed that the fixation is an ever moving process : Authors newly defined Threshold of binocular fixation which was less than 2 degrees this time. 4. Fixation process is seen to vary each time depending mainly on individuals and is found never the same and seems hardly possible to be treated as a simple model as of now. 5. Measurement device is hard to adjust and requires a lot of experiences before having good and reasonable results. And research has to be furthered systematically.
