Results of the Simulation of a Qualitative Information Display

Abstract

Check-reading tasks were simulated to determine the effects of several task- and worker-related factors on human performance. The purpose of this study was to investigate the influence of: operator sex, exposure time, pointer position, percentage of deviant dials, and background color on the accuracy of check-reading dials. Twenty-eight males and 22 females performed the simulated tasks. No difference was found between the 9 o'clock and the 12 o'clock positions. For shorter exposure times (0.25 and 0.50 s), dials with white background were found superior. However, with 0.75 s exposure time the black dial background was found superior. Even though males did better than females overall, there were no differences between the sexes when exposure time was increased to 0.75 s. Performance was found to be independent of the percentage of deviant dials between 1% and 3%.
