Effectiveness of visual communication can best be achieved if the observer be-comes totally involved in the displayed image through a feeling of "being there". This sensation of virtual existence or enhanced reality is activated by the capability of a precise pixel expression and a large visual field display. However, these two requirements are contradictory because view angle per pixel deteriorates as the size of the visual field increases. To solve this problem, a new large visual field display system, based on the fact that human vision is most acute over a narrow area centered on the point viewed, is proposed and its construction is shown. The system consists of a large visual field image and viewed region image. With an eye movement tracking instrument, the gazing point within the large visual field image is measured. And, a viewed region image from an area in the vicinity of the gazing point is optically superimposed on a large visual field image. Next, subjective experiments concerning the limitation of spatial frequency in the peripheral vision region are performed. The result shows the effectiveness of the proposed system.
