The Method of Graphic Abstraction in Visual Metaphor

Abstract

In the design fields, graphics are often a media of communication whose goal is to reach mutual understanding. The process of graphic abstraction is one of the most important methods in visual design. Designers often use it to enhance the recognition and impression of observers. This paper investigated abstraction methods through design software research and designer practice research. The result showed that the major tools used in designer practice research are paintbrushes (traditional hand-drawing medium) and software filters (computer media). Three abstraction methods were identified: a) shape simplification method, b) quantitative reduction and c) software-aided simplification. It was discovered that designers used the programs mainly for the simplification of overall image (plane) and comparatively little to simplify 'points' or 'lines.' In addition, the design software cannot fulfill designers' needs for visual abstraction. The finding of this study hopes to provide valuable references for user instructions, graphic design and computer-aided design applications.
