Shadow Mask Display Visibility: Human Thresholds for Perception of Misconvergence Effects *

Abstract

A psychophysical study was conducted to identify the acceptable limits of misregistration of the color vector beams in a “delta gun” shadow mask display. The criteria for acceptability were the perceptual responses of sixteen male pilots who viewed the display and adjusted the beam convergence to achieve various visual effects. Results are discussed in terms of display image perception and engineering design standards.
