DISPLAY COLOR CODING AND THE LEGIBILITY OF OVER PRINTED SYMBOLOGY,
Abstract
Six experimental subjects viewed a series of dis plays of overprinted colored numbers and in each case counted the occurrences of a particular tar get digit, which varied from trial to trial. Five degrees of symbol overprinting were used, for displays representing each of the 15 possible pairings of five symbol colors. Counting time and errors were interpreted as inverse measures of symbol legibility. Legibility decreased regu larly as degree of symbol overprinting was in creased: compared with conditions of no over printing, trials with full symbol overlap re quired twice as much counting time and resulted in five times as many counting errors. Inciden tal differences in legibility were noted among the particular number symbols used. Thes differ ences were small in comparison to those attribut able to the different colors. This suggests that color is potentially more influential than shape in determining the legibility of overprinted sym bology. (Author)
