Blending Methods: Developing Participatory Design Sessions for Autistic Children.

Over the past two years, we have engaged autistic children in a participatory design (PD) process to create their own, individual smart object. In this paper, we reflect on our methodological choices and how these came about. Describing the design process with one of our participants as a case, we show how we developed participatory activities by combining, blending, re-interpreting and adapting techniques and tools from a pool of methods on the basis of the characteristics of the child, our own skills as designers and the history and context of our collaboration. Reflecting on this practice retrospectively, we seek to make two contributions: firstly, we distill a repertoire of methodological building blocks which draw on our experience of co-designing with autistic children. Secondly, we present a visual tool that captures the process by which we combined, blended and interpreted these building blocks into coherent design activities with a view to provide systematic guidance for future work. While the work presented here is set within the context of designing with autistic children, we argue that the underlying approach can be applicable and useful in a wider co-design context.
