Doors of Perception is a design conference in Europe and India which brought together grassroots innovators to work with designers to imagine sustainable futures – and take practical steps to meet basic needs in new and sustainable ways. Its founder and first director is John Thackara. This hybrid community of practice was inspired by two related questions: "we know what new technology can do, but what is it for?" and, "how do we want to live?". The results are published on the Doors of Perception website, and discussed at the Doors of Perception conference. Numerous people and organizations contributed over the years to the conferences and its organisation. The first editions were supported by the Netherlands Design Institute and Mediametic and people such as Jules Marshall and Gert Staal. In the new millennium the Center for Knowledge Societies organized three of the later conferences in India.
