“I’ve been involved in developing what I would say is the craft of interaction design. A craft is a way of working that you develop entirely through experience without thinking about rationalizing it or systematizing it. And I believe that craft is essential to interaction design, and always will be. But I also believe that there could be ways of thinking about interaction design, ways of generalizing principles from experience and existing knowledge, just as in the twenties general principles about composition and graphic design were developed at the Bauhaus, or a new grammar of film was invented by Eisenstein and written about by Arnheim. These ways of thinking about practice make a platform in which people coming after us can build without them needing to invent everything from the start.” (Gillian Crampton-Smith 2007)
