The NANO Supermarket is a travelling exhibition of speculative artefacts that theoretically use nanotechnology. The products are designed and presented to engage the public on the impact of nanotechnology on everyday life. This research draws on the various visual techniques and conceptual approaches used by speculative designers in relation to the science of nanotechnology in order to understand how the NANO Supermarket engaged a public audience. This thesis analyses approaches to the medium of speculative design as a process of engagement. From this analysis and theorisation of the practice, we situate the case study within the history of critical design.Show less
