STUDIES OF DISPLAY SYMBOL LEGIBILITY. PART XIII. STUDIES OF THE LEGIBILITY OF ALPHANUMERIC SYMBOLS IN THE BUIC SYMBOL

Abstract

The legibility of alphanumerics for BUIC system displays was studied in three experiments. Four fonts, standard Leroy, Idealized Early BUIC, Idealized Late BUIC, and Stimulated Late BUIC, were tested in single-symbol, controlled exposure-time, recognition tests. The Early BUIC font was less legible than standard Leroy; but after some symbol changes were made, the new font (Idealized Late BUIC) was more legible than the earlier font. When the improved alphanumerics were simulated to appear as they do on the display console, they were less legible than the Idealized alphanumerics. Symbol changes are recommended, and BUIC operators are urged to exercise caution in reading the displays.
