Abstract
A study was undertaken to determine the effects of rate and direction of display movement upon the time to find alphabetical targets. Subjects searched for targets which always remained present in a display which moved but did not change. Display speeds somewhat faster than 8 degrees/sec angular velocity (2 in./sec viewed at 15 in.) were associated with decrements in performance. At higher rates of movement, search times for horizontally-moving displays were lower than those for vertically-moving displays. It is recommended that high-speed displays move horizontally when compatible with other system needs.Keywords
