1. In a simulator, a visual system for generating a high-resolution visual image over a wide field of view comprising: image display means; computer image generator; means connected to said computer image generator for projecting a visual image of high resolution onto said image display means, the area of said high resolution image being sized to accommodate the foveal viewing area of an observer observing said image display means; means connected to said computer image generator for projecting a visual image of low resolution onto said image display means encompassing said high-resolution image and sized to accommodate the peripheral viewing area of said observer; means for merging said high resolution image and said low-resolution image to enhance the optical realism of the overall image, both foveal and peripheral views of the observer; means for continuously locating the observer's eye line-of-sight relative to a position on said image display means; and means for continuously positioning the high resolution image substantially at the observer's eye line-of-sight on said display means such that the high resolution image will be encompassed in the foveal viewing area of the observer regardless of where the observer is looking, the transition time of repositioning the high-resolution image from one point on said image display means to another point on the image display means being less than the saccadic suppression time of the observer.
