In this talk, we will explore the field of Design Fiction as a powerful tool for designing futures. By combining the creativity of design with the narrative of science fiction, Design Fiction allows us to imagine and explore possible, desirable and sometimes uncertain futures. We will dive into how this methodology not only anticipates future technologies and trends, but also raises critical questions about the ethical, social and cultural implications of these innovations. Through practical examples and case studies, we will see how Design Fiction has been used in various sectors, from technology and architecture to politics and health, to create provocative and thoughtful visions of the future. The talk will also offer a step-by-step guide on how to implement Design Fiction in your own projects, including techniques for generating ideas, building narratives, and visualizing future concepts. Additionally, we will discuss how this approach can foster interdisciplinary collaboration and open innovation.
