Influence of Vertical Length of Characters on Readability in Mobile Phones

摘要

The visibility of Japanese characters on the liquid crystal displays in mobile phones was studied by measurements of reading time and visual distance, and subjective evaluations. Graphic text was used to prepare various samples with various character heights of 1, 1.25, 1.5, 1.75, 2 and 2.25 times greater than the width of the characters. The vertical length of the characters had a significant effect on the parameters of reading speed and subjective evaluation of legibility. Characters with a height of between 1.5 and 2 times greater than the width showed the highest visibility in this experiment.
