A Study on Font Shapes for 4K LCDs Suitable for Diagonal Display

Abstract

　There are various ways to view digital signage, and the design of digital signage for various views is desirable to make the signage more appealing. In this study, we find out the characteristics of the font which is easy to read when viewed from an angle through preliminary experiments and main experiments. In this paper, we describe the results up to the preliminary experiments. In the preexperiments and the preliminary experiments, we examined whether the visibility of a font varies depending on the angle of gaze and the type of character. Regarding the angle of gaze, changes in the horizontal viewing angle affect visibility, but changes in the vertical viewing angle do not affect visibility. The visibility of hiragana, katakana, and kanji characters differ in visibility. Some characters are difficult to read in hiragana and katakana even if they are the same type. Hiragana and katakana are difficult to read even for the same character type.
