아이덴티티 디자인에 있어 ＂비언어적 문자＂ 속성에 관한 연구

The 21st century modern society has a tendency that functional designs along with needs for cultural experiences are increasing. This trend can be shown in the field of graphic design, and be explained by the phenomenon that graphics seeking visual fun have increased. "The pleasure of discovery" on ambiguous aspects of the graphic designs with visual fun stimulates human's play instinct. This can be described by the case that verbal logos make meanings of obscure non-verbal symbols clear. In the field of Identity design, these kinds of expressions with non-verbal letters are interesting from a aspect that they provide public with not only the pleasure of discovery but also public fun. These non-verbal expressions have the composite characters of phonetic symbols and pictograph. In this point, non-verbal expressions are similar to hieroglyph. Roland Barthes' language's "function of fixation" appeared in semiology can explain that non-verbal expressions make their meanings clear with verbal logos' assistance in delivering messages which should be obscure due to the composite characters of phonetic symbols and pictograph. Defining the aspects of Identity design's expressions with non-verbal letters' characters based on these theoretical backgrounds with hieroglyph, phonetic symbols, pictograph and semiology, we will figure out many expressional characters of non-verbal letters and their practical usages.
