Abstract

In recent years, e-book terminals are spreading rapidly. In the current aging society, there is an increasing need for elderly people to use information devices such as e-book. The readability of characters on e-book displays is important especially for elderly people. Few studies have measured subjectively the visibility of characters on e-book displays. In this study we examined the relationship between the readability of characters on e-book terminals compared with the characters printed on paper. The readability of characters on the displays of e-books deteriorates remarkably as the characters become smaller, especially when the user is an elderly person. Thus, makers of mobile text characters should consider aging so that e-book terminals are readable to all age groups.
