Abstract |
10 student subjects were tested to evaluate the readability of text as a function of 3 different line lengths, 2 different character densities and window heights of 1, 2, 3, 4 or 20 lines. Lines of full and two-thirds screen width were read 25% faster than lines of one-third screen width. Text of density 80 characters/line was read 30% faster than text in a format of 40 characters/line. Text in windows 4 lines high was read as efficiently as text in 20-line windows, and text in 1- or 2-line windows was read 9% more slowly than text in 20-line windows. Comprehension of the passages did not vary as a function of window size. Implications of the results for mixed text and graphics and for limited-capacity electronic displays are discussed. |
