Features and a model for icon morphological transformation

The study proposes several criteria and a system model for morphological construction and transformation of icons. From this point of view, several important concepts, such as meta/actual-use of icons; icon homonyms/synonyms; local/global context; location sensitivity; icon orthogonality/consistency; degree of fusion and combination adequacy; or top-down/bottom-up transformation are discussed. Based on this discussion, a general framework of iconic systems is proposed. In this model, icons are system independent objects, and are morphologically (e.g., incorporation) transformed
