Most design methods used within interaction design originate from other disciplines. As a result, there are few methods which can focus on designing or redesigning interaction in itself. In this paper we present a structured ideation method called Skewing, which is based on changing already identified, interaction-related properties of an artifact. Hereby, designers can generate interesting re-designs whose interaction design differs from the original product. Moreover, the structured approach in Skewing helps in finding the unusual design solutions in the outer rims of the design space. Lastly, Skewing can also be used as a means to teach the materiality of interaction.
