On the Foundations of Interaction Design Aesthetics: Revisiting the Notions of Form and Expression
Lars Hallnäs


Form and expression are basic notions in design aesthetics and design aesthetics education. This is something firmly rooted in architecture, product design, industrial design, fashion design and so forth, but how should we understand these notions in interaction design?
