Visual Perception in the Field-of-View of Partial Binocular Overlap Helmet-Mounted Displays

Abstract

Because of limitations in the size of the field-of-view (FOV) available in helmet-mounted displays (HMD) using the full overlap display mode, where the entire FOV is binocular, partial binocular overlaps displays, which can be convergent or divergent, have been proposed. One consequence of this is a perceptual effect known as luning, which is a subjective darkening in the monocular regions of the FOV, which can in some cases cause fragmentation of the FOV into three regions. A concern is, the possible effect on target identification in the monocular regions, particularly in areas affected by luning. We review data we have collected in our binocular vision lab on the effect of display mode one aspects of visual perception.
