VISIBILITY OF GRAPHICAL CHARACTER E-MAIL IN MULTIPLE LANGUAGES ON MOBILE PHONES

Abstract

Although multilingual information is required by many foreigners in Japan, ordinary mobile phone (MP) models in this country do not support multilingual characters such as Korean or Chinese. Graphical e-mail systems in MPs for sending digital photographs are also useful in sending character mail with unsupported fonts. This paper presents research on the visibility of Korean, Chinese, and Japanese graphical characters on the liquid crystal displays (LCDs) in MPs, by measuring the variables of reading time and visual distance. The dependent relationship between size and visibility of the characters as well as the importance of the quality of the LCD are described. Visibility is also affected by the age of the people using MPs.
