Designers of computer interfaces deal with invisible and nonexistent. Everything what we see or hear while communicating with digital devices has no original shape or size or behavior. These are designers who are giving forms to the matters and explain it to the users… by using metaphors or idioms. It started with a desktop (metaphor) and a double click (idiom) four decades ago, and never stopped. Whatever environment or medium one is choosing a way to build an interface – by analogy to the physical world, or by an invention that has no connection to the users previous experience. This semester students took a linguistic approach to design, connecting idiomatic expressions with design of their own apps.
