Abstract

Resolution thresholds for Landolt C’s and for vernier targets remain the same whether the target is stationary or moving with horizontal or vertical velocities of up to 2.5°/s for foveal presentations lasting 0.1 and 0.2 s. Oblique target motions are tolerated only up to 1°/s. Because visual pursuit is ruled out by randomization of direction of motion and by the short exposure, it is concluded that a stationary retinal image is not a prerequisite for good acuity.
