In this one-day learning workshop, we explore how embodied speculation in participatory design and innovation can help stakeholders imagine, critically reflect and engage in dialogue about the social opportunities and ethical implications of emerging technologies. The workshop starts with a round table discussion about relevant criteria when conducting embodied speculations. We then engage in embodied speculation ourselves, focusing on identifying the social opportunities and ethical implications of Quantified Self technologies for the year 2026. We end the workshop by reflecting on our experiences with these embodied speculations to foster knowledge exchange and learning. We reach out to participants with different professional backgrounds in the fields of design and innovation that would like to learn about embodied speculative techniques and who would like to explore the research opportunities this opens up.
