We investigated how visual noise in the initial estimate of target location affects precision for rapid pointing. Visual localization thresholds (an error measure) rise systematically with eccentricity, doubling at eccentricities of a degree or less. Previous work, which we confirmed, has shown that the precision of pointing, measured by the standard deviation, to a single isolated target is relatively constant over small lateral extents near the midline, and that pointing error is… CONTINUE READING
