Micro-graphics. Icons in visual communication: Between symbolic value and interaction design

Abstract

This paper critically analyses the field of visual artefacts composed of icons, defined as small synthetic graphic symbols that identify actions and functionalities, and allow people to interact with the digital and non-digital devices they use in the scope of their everyday activities. Starting from semantic and semiological considerations, the aspects of codification, interpretation and interaction that involve these systems of signs are addressed, from conception to use. Finally, a paradigmatic case study within icon design is outlined, namely Susan Kare and her decades of experience. Icons – micro-graphics that mediate the interaction between humanity and the surrounding world at every level – inform, orient and communicate, influencing our perception of reality in a decisive way, configured as elementary units of visual language.
