In order to display the multi-media information in our factory and office, it is necessary to make clear how an eye sees the scene. In this paper, we propose the method using the queue theory to make clear how to stay an visual point in some area. The visual field is divided into square mesh (2°×2°), and the traffic intensity is calculated in each mesh. And 19 works which have from 2°×2° to 45°×60° visual field are evaluated by the proposed method. It is shown that the visual point mainly moves in 5% area of visual field, and 80% of visual points stay in 2% area of that. As the gazing region becomes small, the traffic intensity becomes high. And the Visual point visits same area repeatedly. The traffic intensity becomes too high in monitor work (0.23-0.30), and decreases gradually in the order of assemble work (0.18), VDT work (0.05-0.17), And it becomes extremly low in walking (0.05 to 0.08).
