Abstract
Although each retinal image is two-dimensional, binocular geometry requires complete representations of field of view to be three-dimensional: the set of visual directions from which light can impinge on either retina can be fully represented in no less than three dimensions. An easily interpretable means of representing environmental space as viewed by a human operator would have wide application in many areas of human factors engineering. This paper discusses a method for delineating and testing hypotheses about the relationship between the retinal images and the three-dimensional visual space they serve, under the conditions of (a) changing eye position, (b) occlusion by structures that are part of or are mounted on the observer such as the bony facial structures, spectacles or headgear, (c) occlusion by environmental objects, (d) defects of the visual field such as the normal blind spot, areas of temporarily reduced visibility due to local adaptation and photopigment bleaching effects, and (c) variables that alter the focus of environmental imagery on the retinas.
