Advancements in mixed-reality (MR) systems have concentrated on the technology required for implementation, providing proof-of-concepts by means of technology-tailored usage scenarios. These systems have been tested mainly on well-contained tasks and applications specifically developed for these platforms. The potential impact of such techniques on actual work practices hence remains largely unexplored. We plan to investigate this practical relevance in more detail for industrial designers. Specific activities have been identified during a full ethnographic study conducted by means of Cultural Probes and Workshops with representative participants. For one such activity, creating mood boards, a new MR interaction concept will be designed and evaluated. We will continue to use participatory design techniques to involve industrial designers at different stages of the design cycle.
