Samenvatting
12 of the most frequently confused alphanumeric symbols were selected from Leroy and L/M fonts and studied for their relative legibilities. Human subjects saw the symbols with 5 different brightness contrast rations, and errors were recorded. The L/M font gave significantly fewer errors at all contrast ratios. It was concluded that the L/M font will yield better legibility than the Leroy font and that a greater reduction in errors can be obtained by using the L/M font than by increasing the contrast of a display using Leroy symbols.
