As industrial designer I am bound to needs and wishes of society and the consumer. Artists have for more far more freedom in their choices and designs, because they don’t have to think about these consumers. That also allows them to have more freedom in interaction. An artist doesn’t need to make an object or product with interaction that is intuitive or easy for the user.
I am especially interested in the way artists use estrangement or defamiliarization in interaction and art. Familiar objects which have a surprising unfamiliar interaction, such as Scaredchair, have always inspired me. Feeling unfamiliar with a familiar object creates a surprise effect. It allows fun and playfulness. Artists also use this the other way around: unfamiliar objects with a familiar interaction, like the wooden mirror. Unfamiliar objects combined with an unfamiliar interaction are less interesting to me.

Why is this so? How can I use this defamiliarization in my product designs? When I use unfamiliar interaction in my designs, would they then automatically lose their functionality? When does art become familiar?
