Peripheral Contrast Thresholds for Moving Images

Perceptual enhancement for image motion in the visual periphery was evaluated by threshold measurements with a moving-bar stimulus. Lowered peripheral thresholds were found for both forward and backward image movement with no significant elevation of the contrast threshold for an image in motion out to 55° eccentricity from the fovea. Either real or phi-phenomenon movement is recommended for the display of emergency or mission-critical signals.
