Before widely adopting in the real life, Emerging technologies and design concepts require appropriate user studies to explore demands from users. Smart cockpit is a typical fields driven by cutting-edge technologies, and vehicles are becoming more intelligent touchpoints empowered by V2X technologies. A repeated, correlative and continuous framework was employed for future-oriented user study such as smart cockpit’s connectivity capability in the context of V2X, by presenting the Participatory Design Fictions with Mixed Reality, which aims for stimulating imagination of the participants to gather their views and discussions about the future. Thematic analysis, discourse analysis and creative analysis were adopted to evaluate this framework and method. Results indicated that Participatory Design Fictions with Mixed Reality provided researchers with more in-depth insights about the preferable futures articulated by different groups when conducting future-oriented, demand mining-oriented user study as a effective tool and method.
