The Presentation of Different Visual Information to Each Eye
Abstract
When completely independent images are presented to each eye, fusion normally cannot occur. Instead, either an involuntary alternation occurs between the two images (binocular rivalry) or one of the images is 'suppressed,' and visual performance is degraded. If the images are only partially independent (see-through display), the observer can control this alternation and presumably reduce degradation. During the development of one version of the Honeywell Helmet Mounted. Sight and Display (HMS/D) system, it was suggested that presenting a gun-sight reticle one eye and target imagery to the other eye either sequentially, or with an inter-ocular delay interval (IOD), might minimize binocular rivalry. It was hypothesized that if binocular rivalry did exist, and if it occurred even when only temporal summation linked the images to the two eyes, visual performance would be best when display imagery was presented to only one eye, and worst when presented to both simultaneously. Further, performance would fall off in a regular fashion between these two extremes as the IOD was decrease. Statistical analysis of the data failed to confirm these hypotheses, and it was concluded that the influence of binocular rivalry on target recognition tasks was negligible with a see-through display.
