“…This dimension has, however, provided disappointing results within the normal ranges of vision and hearing. Several studies have reported that observers with the most acute vision or hearing do not necessarily make the best monitors (Tiffin and Rogers 1941, Baker 1960, Baker et al 1962, Nelson and Barany 1969, Megaw 1979. Paradoxically, sensory impairment has been found to be a beneficial factor in vigilance performance.…”

“…Research designed to relate static and dynamic acuity and to develop a OVA test for industry was completed by Nelson (1969). Verification of the theoretical relationship is dependent upon the assumption that out of focus blurring of a static image produces a stimulus identical to the effect of a rapidly moving image.…”

ariables~ffecting Dynamic Visual Acuity are lmportant ln the design of industrial inspection tas~s. T~e objective of the present study was to lnvestlgate the effects of target-background contrast, target size, and linear velocity upon OVA.Photographed block landolt rings were placed on white and grey backgrounds to produce ten uniformly graded contrast levels between target and background. These were then mounted on standard 35 mm.photographic slide frames (2 in. x 2 in.). Gaps ln the rings were oriented toward the corners of the frames.For a given viewing time, an increase in linear velocity resulted in a marked decrease in OVA abf l f ty . .Al so , for a.given linear velocity, an lncrease ln vlewlng tlme resulted in an increase in OVA ability. Contrast levels and display width also affected performance.
