Interaction for the control and use of new media and technologies can take many forms. The familiar interaction with displays on which software applications are used is extended by control via speech, gestures and body movements. Under the semester topic „Rethink Interaction!“ it was found out which further interaction possibilities are designable and desirable. The results are very different projects to rethink interaction. For example, there is the casual interaction, which happens incidentally through the habitual use of an object, there is the participatory interaction, where something is created together, and the unconscious interaction, where the meaning of the interaction is only understood through the use. What they all have in common is a new understanding of materials: different materials are used to communicate, for example, through touch, stretching and pressure.
