The effects of physical image quality on reading and on perceived image quality
from CRT and hard copy were studied in this experiment. The results showed
that as the image quality of a display increased, indicated by an increase in the
value of the MTFA, the reading speed increased and subjective image quality
V; ratings increased. This change in reading speed and perceived image quality occurred in the hard copy as well as in the soft copy condition. Image quality,
therefore, is concluded to be the major determinant of subjects' performance
with respect to displayed information. This implies that if the image quality
the displayed text ls the same on the display techniques used, subjects will read
from CRT displays as fast as from hard copy displays.
