Researchers of the CoHERE project created an immersive experience for heritage experts from European museums, to tackle a difficult scenario that might exist in our future. Using speculative design and design fiction methods, they imagined a future where museums can no longer keep their full collections and must delete 20% every year. To determine what to delete and how this challenge would affect the visitors’ museum experience of the future, on the day of the workshop, the participating experts together formed the Deletion Bureau… A very interesting workshop model!
