LEGIBILITY OF CHARACTERS ON MOBILE PHONE DISPLAYS

摘要

Mobile phones are very popular around the world today, and the use of text email with short message service (SMS) is spreading. In this study we evaluated the legibility of characters on the liquid crystal displays of mobile phones. The subjects were 75 persons aged from 19 to 80 years (42.5 ± 18.2 years). When characters are small, younger people assure readability by shortening the viewing distance. Conversely, elderly people find it far more difficult to see and read small characters.
