Assessment and Development of Oculomotor Flying Skills by the Application of the Channel Theory of Vision.
Abstract
Pilot's landing and formation flight performance on the ASPT simulator correlated with visual sensitivity to an expanding flow pattern and with depth tracking test errors. Aircraft flying grades correlated with flow pattern test results. As stimuli for motion in depth, either texture changes alone or changes in object size alone are effective, but the presence of static texture dramatically reduces the effectiveness of changes in object size. In contrast, to the traditional emphasis on static picture quality in visual simulation, this finding emphasizes the importance of dynamic parameters in simulation fidelity. In terms of monocular two-dimension simulation of motion in depth, our findings suggest that in many conditions the presence of texture reduces stimulus effectiveness, and at best the presence of texture adds little to the effectiveness of an untectured stimulus. Subjects cannot accurately locate the center of expansion of an expanding flow pattern in the presence of translational motion of the retinal image when there is no accompanying geometrical distortion. However, subjects are very sensitive to geometrical distortions of the retinal image, and can accurately judge the location of teh maximum rate of object magnification even in the presence of translational motion.
