For the semiotically inclined, see Social Semiotics, from the Glossary of Multimodal Terms:
“In the context of multimodality, the implication is that all modes should be studied with a view to the underlying choices available to communicators, the meaning potentials of resources and the purposes for which they are chosen. From a social semiotic perspective, this includes study of how communicators create texts (including the role of technology) and how people interpret texts.”
