The bits of this space that one can ‘see’ are determined by one's knowledge of the user needs and one's own skills. Co-design is a way of exploring that space in a way that alleviates the myopia of one's own viewpoint and bias. As one traverses this space one traces a trajectory according to one’s skills and learning and according to the users’ expressed requirements and their learning.enThis is the author postprint version of a book chapter published by Wiley.
