Due to the rapid population growth of older adults, independent living is becoming a dominant issue in our society. Most older adults are active and want to enjoy the latter stages of life as fully as possible. With the expansion of new technologies, the use of computers has become an important aspect of independent living; the ultimate goal to increase one's quality of life. Consequently, it is important to provide legible and stimulating visual displays on the computer screen for this older population. This study focused on typographic legibility factors while using a computer screen. Four different colored backgrounds (white, gray, yellow and cyan) and two different font sizes (12 pt and 14 pt) were tested by 64 people, 55 years of age and over. Subjects were randomly assigned to one of eight treatment groups. The dependent variables within the study were reading speed and comprehension. The independent variables were font size and colored background. The results indicated that there was no significant difference between 12 pt and 14 pt font sizes in reading speed and comprehension. However, there was a significant difference in background color in reading speed. The gray background was significantly less legible than the yellow background.
